iPhone Battery mAh List – Check Capacity & Performance all Models

Despite having the most powerful iPhones in the market for over 3 months now, it is hard to say whether we’ve reached the level of peak smartphones yet or there’s still time for that tag to be presented to some iPhone model in the future. But it must be said that Apple made some remarkable changes to its flagship iPhone models and that the iPhone 14 Pro and iPhone 14 Pro Max gives users the ultimate battery experience.


This usually means that your iPhone will now last longer, charge faster, and drop battery slowly in comparison to its predecessors. If we’re talking in terms of iPhone battery mAh, then the iPhone 14 Pro 3200 mAh battery and the iPhone 14 Pro Max comes with a 4323 mAhbattery; which is awesome!
But the surprising bit comes with the iPhone 14 Plus, which starts at Rs. 89,900, and has a 4325 mAh battery; the biggest and best battery backup that we have seen in an iPhone so far barring the iPhone 13 Pro Max. Safe to say , Apple is fulfilling its promise of delivering reasonably priced iPhones with the best battery backup.


But that’s just the case of the latest generation of iPhones in the market. What’s the story as we go behind or go back to a few yesteryear models. Stay tuned as we provide you with the latest iPhone battery mAh list – all the top Apple iPhone battery mAh data that can help you decide what iPhone suits your needs the best if not for the latest iPhone 14 series.Key Takeaways – For Those Who Are In Awe With iPhones

With the above-mentioned list, you can deduce that the iPhone battery capabilities vary from model to model and year to year and there’s no clear indication from Apple suggesting that all their future iPhone models will boast a better battery life. This can be reflected by comparing the iPhone 7 battery mAh and the iPhone 8 battery mAh. Where the iPhone 7 was boasting 2220 mAh, the successor model didn’t exactly get a promotion in terms of battery.


Similarly, the iPhone XR was an upgrade for the iPhone X but in comparison, the iPhone XR battery mAh(2950 mAh) was reduced by a small margin in comparison to the iPhone X battery mAh (3000 mAh).
But if we see the iPhone 7 battery mAh (2220 mAh) in comparison to the iPhone 7 Plus battery mAh (2900 mAh) then one can deduce that the Plus and Pro models – because of the device’s size – can boast of a better and longer battery performance than the base iPhone models.


Then again, if we put to test two pro models (that are relatively new), the iPhone 11 Pro Max battery mAh (3969 mAh) easily puts to bed its competitor and successor in iPhone 12 Pro Max. The iPhone 12 Pro Max battery mAh (3687 mAh) finds no upgrade where other things do as we shift from iPhone 11 series to iPhone 12 series. In comparison, the iPhone 12 Mini battery mAh (2227 mAh) legitimises the problem of space and the lack of a large battery in the mini models.
Even though a lot of the previous-year Apple iPhone models are becoming obsolete and most will not have the power of 5G enabled, there are still some worthy devices out there if we’re talking plainly about their battery and camera performance.


These are some of the recommended iPhone models in terms of battery life:Of course the Apple iPhone 14 Pro Max, iPhone 14 Pro, and iPhone 14 Plus are the latest and the go-to options for people but if they’re thinking of shelling a few thousand bucks less, then the iPhone 13 Pro Max has the best battery life in comparison to all other iPhone models. It boasts a 4352 mAh battery, which is the best in the iPhones segment.
Apart from these, the following have a reasonable battery life in accordance with their current market price:


1. iPhone 6S Plus: even though a yesteryear iPhone, the 3500 mAh battery life was considering brilliant the phone was launched in 2015.
2. iPhone X: after a series of iPhones with an average battery life, iPhone X offered a 3000 mAh battery, which was quite a development.
3. iPhone 11 Pro & iPhone 11 Pro Max: the iPhone 11 series took a new turn for the improvement of the new-age iPhones as iPhone 11 Pro Max offered a staggering 3969 mAh battery, where the iPhone 11 Pro also came with an impressive 3048mAh battery.


 4. iPhone 12 Pro Max: as mentioned earlier, the Pro Max models are the biggest in terms of display and overall size and the iPhone 12 Pro Max battery mAh (3687 mAh) is still impressive and quite good for the device.
5. iPhone 13: despite being the base model, the iPhone 13 offers a 3227 mAh battery and that’s great considering the sleek and slim size of the iPhone 13.

These were some of the takeaways after comparing all the iPhone batterycapacities and their respective mAh or milliampere per hour of energy charge. You can make sure you revise this basic info before purchasing a new iPhone or going for a refurbished one.

What’s Draining My iPhone’s Battery? What Can I Do About It?

There may be times when you feel your iPhone’s battery life isn’t what it used to be, which really sucks.
There’s nothing more important in any chargeable device than its battery. The good news is that you might be able to do something about it. 
Sure, it’s possible that your battery’s a bit older and doesn’t hold as much charge as it used to. But if your iPhone is fairly new, there might be something else that’s draining your battery. 


Fortunately, you can see what’s actually draining your battery with your iPhone’s settings. Here’s all you need to know. 
How to See What’s Draining Your iPhone’s BatteryMost of the time, your iPhone won’t just lose battery life on its own. Usually, the reason behind it is an app or a game that’s been working non-stop—whether it’s because you’re using it or it’s working in the background. 
The good news is you can see which apps and games are consuming the most energy on your iPhone by following these steps: 

The green graph is for your battery level throughout the day.The blue graph is for the time your iPhone was active.You can see your report for the last 24 hours and the last ten days of activity and battery usage, which will give you more insight as to what’s been happening to your iPhone’s battery. 
If you scroll down, you’ll find the apps that have been draining your battery the most.If you tap on it, you’ll see your activity on each app. Meaning you’ll see how much time that app or game’s been open or was used.

This is the part that’ll let you know exactly what’s draining your battery. You can use this report to see if an app or game is too much for your iPhone’s battery to handle—which does happen—or if you’re using an app or game too much—which happens even more often. 
Understand Your Battery HealthThere’ll be times when your apps aren’t really consuming that much battery from your iPhone. If that’s the case, it’s possible that it’s your battery’s fault. 
You’ll need to understand if your battery’s still healthy or if it’s not working at the appropriate capacity anymore.

Here’s how:
Open the Settings app.Scroll down and tap on Battery.Select Battery Health.How to Access Battery Health iPhoneSergio Velasquez / iDrop NewsThis is where you’ll see how well your battery’s performing. And, unless you have a brand new iPhone, chances are its maximum capacity isn’t at 100% anymore. Don’t worry, that’s normal, and it’s just what happens to all rechargeable batteries over time, unfortunately.
Your iPhone’s battery goes by charge cycles, which happens every time you fully recharge your iPhone from 0% to 100% total in any variation of charge times.Your iPhone’s battery is designed to retain up to 80% of its original capacity after 500 complete charge cycles. But the more you charge it; the less capacity will have over time. If your iPhone has a maximum capacity of less than 60%, it’s normal if you feel like the battery’s draining too fast. 

What Can I Do to Help My Battery?

Other than quitting using so many apps and games or replacing your iPhone’s battery, there are a lot of ways to increase your battery life. So there are still ways to salvage your battery.
One of the most basic tips is to keep your iPhone updated. That way, your iPhone will perform better and consume less battery.


iPhone Battery Settings TipsSergio Velasquez / iDrop NewsYou can follow your iPhone’s battery tips, too. If you go into your battery settings, as we previously showed you, your iPhone might give you some tips on how to preserve battery life. Granted, they aren’t anything groundbreaking, but they’ ll still help you keep your battery from draining too fast.


You can also try reducing your background apps activity by going into Settings > General > Background App Refresh. You can disable apps so they won’t run in the background even when they aren’t open. 
Another quick solution is to disable Location Services. You can do this by going into Settings > Privacy > Location Services. Apps will use your location to give you a better experience, but that consumes more battery. You can disable Location Services altogether or choose which apps will have access to your location (recommended). 
If your battery problems come from your iPhone’s hardware, you’ll need to consider changing the battery. If your iPhone’s fairly new, Apple provides a one-year warranty that covers faulty batteries. If not, you can still talk to Apple Support, and they’ll change your battery for a charge. 


Last but not least, you can try resetting your iPhone. You do this by going to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings and following the instructions on your iPhone. Keep in mind, though; this will completely delete all content and settings your iPhone has so you can start from scratch. So it’d be better if you do this only after you backup your iPhone properly. 


If you manage to solve the problem, you should start taking better care of your iPhone’s battery. Even if we don’t see it, it’s one of the most important parts of our iPhones, so try to take care of it if you want your iPhone to last for years. Here’s how.

How to Turn Off Battery Health Management on Mac

A new Battery Health Management feature on Mac tries to extend the laptop’s battery life by not fully charging it. Thankfully, you can still control the charging cycles by turning the feature off.


macOS Catalina’s 10.15.5 update brought a new Battery Health Management feature, which is designed to extend the battery life of Apple’s MacBooks by changing how often the device gets fully charged. Want your MacBook to always be fully juiced? Here’s how to turn the feature off.

How Does Battery Health Management on Mac Work?

Battery Health Management on the Mac is similar to the Optimized Charging feature on iPhone and iPad, but it’s designed for a different use case. It only works on MacBooks that ship with USB-C Thunderbolt 3 ports (everything including the 2016 MacBook Pro, 2018 MacBook Air, and after).
You see, if you use your MacBook with a monitor, it probably stays plugged it most of the time (like mine does). This means that your MacBook is almost always fully charged.


RELATED:How IOS 13 Will Save Your IPhone’s Battery (By Not Fully Charging It)
This is great if you’re in the habit of heading out with your MacBook and charging it multiple times a day. But if your MacBook’s battery is always fully charged up, it’s actually degrading its battery life and battery health.
The way that the Battery Health Management feature takes care of it is by not always fully charging your MacBook. This way, it can reduce the number of full battery charge cycles and prolong your battery life.

Now, Apple says that it’s doing this smartly, by monitoring your MacBook’s usage and only stopping the MacBook from hitting 100 percent charge levels if it knows that the MacBook is going to be plugged in for a long time (based on your usage patterns).


But the feature isn’t foolproof, and it’s turned on by default if you buy a new MacBook or after you upgrade to macOS Catalina 10.15.5 (or later). What if you always want your MacBook to be charged up to 100 percent, so even if you want to head out, you know that your MacBook won’t run out halfway.
You can do this by disabling the Battery Health Management feature altogether.


How to Disable Battery Health Management on MacBattery Health Management is an Energy Saver feature. To disable it, click on the Apple icon in the top-left corner of the menu bar and then select the “System Preferences” option.
Click on System Preferences button from Apple menu in menu barHere, click on the “Energy Saver” button.


Click on the Energy Saver option from System PreferencesNow, click on the “Battery Health” button found in the bottom toolbar. Here, uncheck the Battery Health Management” option.


Click the Battery Health button and then uncheck the Battery Health Management optionFrom the confirmation box, select the “Turn Off” button to confirm.
Click the The Battery Health Management feature has been disabled on your Mac and it will now charge regularly.

How to care for your laptop’s battery and extend its life

Taking proper care of your laptop’s battery is important for ensuring your mobile machine can run as long as possible. Although battery technology has evolved in the background, outdating “best practices” from a few years ago, there are still a number of ways you can extend (or reduce) your laptop battery’s health. We’ve rounded up the top tips for how to care for your laptop’s battery, from how long you should leave it plugged in to how low you should let the battery drain.


Unlike many desktop computers, there isn’t a one-size-fits-all approach to laptops. Every machine is a little different, so finding out as much as you can about your laptop and its battery is important. Our tips apply to lithium -ion ​​batteries, which are, by far, the most widely used batteries in modern laptops.

All laptop batteries are built to handle a certain number of charge cycles, usually somewhere around 500 full cycles — and sometimes even more. Essentially, a charge cycle equals one full discharge down to 0% and then a recharge back up to 100%. A discharge down to 50% and then back to 100% would equal half a cycle. Over time, each charge cycle decreases a battery’s capacity from its design specifications, meaning that the fewer times you drain it, the longer the battery lasts — all other things being equal.


So, where do you start? You can begin by visiting the power settings corner of your laptop and learning how your battery works and what battery settings to enable. Also, pay attention to hibernation modes. Ideally, you want your laptop to enter into hibernation before the battery is totally drained — as well as during downtime when you won’t be using the laptop for a while.


To save even more power, take a tour of your apps and quit any that are running in the background and steadily eating into your battery life. On Windows 10, for example, we suggest you search for and enable the Battery Saver. This mode will automatically turn on when your laptop reaches around 20% battery life (more down below on why this is particularly important). This will automatically block background apps, keep your features like Calendar from syncing or pushing notifications, lower screen brightness, and various other changes that will conserve your battery so you can get to an outlet ASAP.


For MacBooks, look into enabling Power Nap so you can put your Mac to sleep without worrying about it skipping important tasks, allowing you to save automatic more battery life. Enabling graphics switching can also help Macs save energy by switching to a lower graphics mode when engaged in simple tasks (like text-based work where graphics aren’t as important).
There are plenty of manual changes you can make here, too.

You can safely shut down things like cloud storage and messaging applications that may be running in the background. You can also manually reduce the amount of power you’re using by shutting off Wi -Fi and Bluetooth when you’re not using them, turning off optional features such as keyboard backlighting, and generally reducing the number of components burning power. Both Microsoft and Apple have guides explaining the process further.


Keeping your battery in zonelaptop chargingFrameAngel/ShutterstockIn ancient, less enlightened times, there was a problem called “battery memory” that caused nickel-metal hydride (NiMH) batteries to “forget” their full charge capacity and start charging at lower and lower levels. This problem doesn’t exist any thanks longer to modern lithium-ion batteries, but it has led to a lot of poor advice and arguments about battery care based on outdated information. It’s time to clear the air.


Contrary to some recommendations, you don’t need to routinely discharge a lithium-ion battery completely and then recharge it to somehow reboot or calibrate it — this is a destructive practice that’s very hard on your battery. Whether or not it’s a smart idea to perform a complete discharge a couple of times a year remains an unanswered question. Generally, the consensus seems to be that letting your battery discharge (without bottoming it out — aim for around 20%) and then charging it when possible is the best practice.
Next, there was a time when users were advised to refrain from keeping their devices plugged in, based on the idea that letting a battery charge to 100% could wear the battery out more quickly. Today, however, modern devices are designed to stop charging at 100%, so keeping them plugged in doesn’t impact the battery’s lifespan, according to Battery University.


As with manybattery-related questions, the issue of keeping your laptop plugged in when it’s reached full capacity is hotly debated, so there’s nothing wrong with turning your machine off and unplugging it if you feel more comfortable doing that. But generally speaking, the best thing you can do for your lithium-ion battery is to avoid letting it discharge below 20%. Plug it in and charge it when you can, 
When a laptop battery gets too hot, the electrochemical reactions inside speed up — but that doesn’t mean that the battery grows more efficient. Instead, the battery is now producing lots of energy that it cannot use and cannot safely route to any hardware. This creates even more heat, compounding the problem. Not only can this eventually damage the inside of the battery permanently, but it also wears the battery out with a bunch of chemical reactions that aren’t necessary but burn through a battery’s lifespan anyway.


Today’s lithium-ion batteries are durable, but they can only take so much heat. For example, if you are charging your battery and it starts to get overly warm, perhaps because the CPU or graphics processor is working hard or the environment is overly hot , then shut the device down and pop the battery out if possible. Give it a break so that it can cool down, or you can move it to someplace with a lower temperature. Many modern laptops have sealed batteries, in which case shutting the machine down and letting it cool is highly recommended if maximizing the battery’s lifespan is your concern.
Likewise, keep the laptop off of your lap. If discomfort isn’t a good enough reason, with many machines, you’re also making the problem worse by blocking vents. You’ll want to make sure that both vents that pull in cool air and those that expel hot air are able to do their jobs.


Finally, and perhaps most importantly, you should avoid placing your laptop anywhere it might become hot. That includes your car on a hot summer day, beneath a window that gets direct sunlight, or near a space heater. Unusual conditions such as these can do a lot of damage to a battery in a short period of time, though you may not realize it immediately.


Cold temperatures usually aren’t a problem down to a certain point, and storing a battery in a cool place is recommended, but don’t leave your laptop in freezing temperatures. Too much cold can also kill the battery permanently or reduce its lifespan.

How to give your cell phone battery a boost

Cell phone battery power can be a precious commodity,especially during summer. Changing a few settings on your phone can be the difference between your battery lasting through the day or going dark.
Our cell phones are such a huge part of our lives that seeing 7% on the battery indicator can be as alarming as feeling ourselves about to pass out. But while we all know what to do to boost our own energy, it’s not always obvious how to keep our handheld devices fully (or partially) charged.
To that end, DealNews has gathered up the 10 best tips for squeezing extra life out of your phone’s battery.


Knowledge is power! Before you start tweaking things to extend your battery life, see where your power is going. This process varies a bit from phone to phone, but in general:
Android phones: Settings > BatteryiPhones: Settings > Battery > Battery UsageThis will give you an idea of ​​what your biggest drains are and let you effectively target your battery conservation efforts.


Reduce Screen BrightnessManually reducing your screen brightness is one of the most effective things you can do to improve battery life, though you’ll likely have to manually increase it again when you’re outdoors in order to read the screen. Some people have found they can nearly double their battery life by going from maximum to minimum brightness.


Get the Monitor Stories you care about delivered to your inbox.
Note that you must change this manually. You may be familiar with your phone’s “auto-brightness” feature and assume it’s already managing this for you, but that’s not the case. While this setting will change your brightness for you (and save battery when you’re in low-light situations), it’s still usually a battery drain.


Why? When auto-brightness is on, the phone is constantly checking its sensor data and doing calculations to determine the appropriate brightness, which often takes nearly as much energy as the feature is saving (or more!).
Turn Off Unused HardwareGPS is usually the largest and most noticeable battery drain, but Bluetooth, WiFi, and your mobile data antennae use power, too. While you may be loath to cut yourself off from the world, you probably aren’t using WiFi during your nature hike , and some people may rarely or never use Bluetooth. If power’s tight, cut down your data links to what you’re really using. It might not save a ton of energy, but every little bit helps.
Turn Off the Vibrate FeatureThe motor that makes your phone vibrate actually takes a fair amount of juice to power, and can drain your battery quickly. If you’re low on battery, make do with visual or audio alerts.

Limit Background Data UsageYou may be spending battery power running apps in the background. Some may be apps you downloaded and forgot about. Others may have been installed on your phone before you got it. Check what’s running on your phone right now and shut down (or uninstall) anything you don’t need all the time.


Android phones: Press the task-switching button to see what’s currently runningiPhones: Double-tap the home buttonTurn off NotificationsDo you really need to know instantaneously when someone has “liked” your Facebook status? OK, maybe you do. But if you can wait until you open the app to get updates, you’ll save a little juice. Many of your apps will fetch fresh data on their own without interaction from you. You may need to leave some of them running (like your email), but you may be able to do without others, like Instagram, Facebook, or Twitter.


Android phones: Settings > Apps. Then choose individual apps and uncheck “Show notifications”iPhones: Settings > General > Background App RefreshYou may find you can further preserve battery life through individual app settings. For example, you could reduce email sync frequency or disable auto-upload of photos.


Keep Your Apps UpdatedThis one’s simple enough: Make sure you’re running the most recent version of all your favorite apps. Developers often optimize old code to run more efficiently.


Enable “Power Saving Mode” (If You Have One)Not every phone has a power saving mode (iPhones running older operating systems don’t), but if yours does, it can be a quick way to dramatically decrease your drain in a pinch. Check your “Settings” menu to see if the option is listed.
Beat the HeatWhile it might not make a difference to an individual charge, heat can degrade battery performance over time. Try not to leave your phone lying in direct sunlight, and consider changing or removing your case if you frequently notice it running hot.

Don’t want to fiddle with all these settings? Pick up a portable charger and keep it topped off, so you always have an extra power source in a pinch. Many modern cell phones have between 2,500mAh and 3,000mAh batteries, and DealNews regularly lists battery backups even above that range for under $10.
If you’re willing to pay a bit more, you can easily find portable power banks that have 20,000mAh or more. That’s enough for a day’s use of even the most power-hogging applications, or more moderate use for extended periods — such as camping trips or power outages.

Explained: Why modern smartphones don’t have removable batteries and how does it affect consumers

Apple started the trend of offering non-removable batteries to phones with iPhones.Phone makers had no choice but to comply with the latest trends and make sacrifices as consumers wanted more sophisticated smartphones. It was normal for phones to have removable batteries up until early 2010 . Even laptop manufacturers gradually stopped making devices with removable batteries. Let us whether discuss removable batteries are good for consumers. Let’s start with the advantages of non-removable batteries that made them a necessity for modern smartphones.

Advantages of non-removable batteriesSafety of the batteries and consumersBatteries have a thin electrolyte that separates the cathode and anode electrodes which store the energy. The electrodes can generate a lot of heat by causing a short circuit if it comes into direct contact. Moreover, this can lead to more internal thermal reactions that could eventually lead the battery to explode or burst into flames. Battery technology has developed batteries a lot in the past years, yet they are inherently dangerous.

To prevent accidental damage removable batteries need a hard plastic case, especially when they are not connected to a phone. Plastic cases add to the weight and bulk of the smartphone. So, engineers thought of installing a permanent battery when consumers demanded slimmer, lighter designs They ensured that the smartphones should be able to protect the batteries as they are non-removable.Improvement in battery technology

Modern smartphones last longer on a single charge as they come with lithium-ion and lithium-polymer batteries. This development of battery material and capacity helps phones to last all day even after consumption of battery increases for better displays and more powerful chips.The increase in capacity also means that users don’t need to have a spare battery to swap out in the middle of the day. Moreover, there have been improvements made in charging speeds as most modern phones take less than an hour to get fully charged .Protection from wear and tear

Smartphones are getting more expensive every day as they are getting more sophisticated. So, consumers want these devices to last longer and have a lot of protection. Consumers want these devices to withstand regular wear and tear and protection against occasional spills and drops.So, smartphone makers have sealed the outer case to make their devices more durable. But, users lost access to replaceable batteries as they got sealed. Furthermore, it is tough to design a slim and light device with a removable outer case.

Providing tracking abilities to the devicePremium smartphones lure thieves as they are expensive and are easy to steal and resell. Not just the device, but users also lose some highly sensitive data including financial information. So, smartphone makers allow passive phone tracking even if the device is switched off. This feature allows users to track their devices which acts as a defense against smartphone thefts.

But, the tracking capability can be killed by removing the smartphone’s battery, which is its power source. It becomes impossible for thieves to remove the batteries without equipment and expertise if it is sealed inside your phone’s case. The non-removable battery helps you to track your phone if it is missing and even switched off.

Disadvantages of non-removable batteriesThe non-removable batteries come with a lot of advantages, yet users still lose out on some functions and features with them. Now let’s talk about some drawbacks of non-removable batteries.Swapping batteries vs Charging batteries

Charging outlets and power banks takes time to charge your devices, especially if they are older ones. You have to wait about 15 -30 minutes to get your phone fully charged, even if both your power bank and smartphone have the latest fast charging.
On the other hand, replacing an empty battery with a fully charged one will most likely take a minute. Moreover, slim spare batteries are way lighter than smaller mid-sized power banks. Power banks add more weight and use more space in your luggage.Possibility of batteries bloating up

Smartphone batteries can also bloat up and this problem still exists even after all the advancements in battery technology. In such cases, the battery’s safety is compromised and users have to replace it immediately.

Replacing the old bloated battery with a new one is an easier process for removable batteries. But, most modern users have to take their devices to an authorized service to replace it as they usually come with non-removable batteries. Whenever a non-removable battery bloats up, it forces the case to crack open and can damage your phone’s protection.

8 Essential Tips To Keep Your Phone’s Battery Healthy

That phone in your pocket is a modern miracle. Ditto the laptop on your desk, the tablet in your backpack, maybe even the watch on your wrist. And regardless of what each is capable of, they all have one cornerstone component to thank, one that you probably ought to know how to take care of: A battery.


The first step to knowing your device’s battery is to narrow down the kind. The first kind you might think of (and the kind you probably grew up with) are nickel-metal hydride, or NiMH batteries. These, generally, are the ones that look like a normal disposable batteries, except you can plug them into a wall charger for some extra juice whenever your TV remote dies.


The batteries in your modern-day gadgets—from iPhones to laptops to Bluetooth headphones to tablets—are a different beast entirely. These are lithium-ion (aka li-ion) batteries, and they have some pretty significant advantages over NiMH and other rechargeable batteries that came before. Lithium-ion batteries are also totally different from straight-uplithium batteries,which aren’t rechargeable.


That old saw about how you always need to charge your battery all the way up, and use it until it’s dead? Memory effect, as it’s called, affects NiMH batteries but it doesn’t apply to your phone. In fact, you’re phone’s battery hates when you do that. Similarly, lithium-ion batteries don’t need to be “calibrated” with a full charge and a full discharge when they’re new.
Li-ions can pack a lot of power into a small size, and they don’t lose too much of that energy to leakage when they’re not in use. It’s a combination of these factors that make them great for your portable gadgets.


How does a lithium-ion battery work?All batteries work by having two electrodes—an anode and a cathode—with a bunch of a material called electrolyte between. When you plug a battery into a completed circuit, a chemical reaction starts taking place at the anode and electrons start building up over there . Those electrons want to travel to the cathode, where it’s less crowded, but the electrolyte between these two parts keeps the electrons from taking the short way there. The only way through is the circuit that the battery is crammed into, and those electrons power your device in the process. Meanwhile, the positively charged lithium ions the electrons leave behind travel through the electrolyte to meet the electrons on the cathode side.


Once all the electrons have made the trip, your battery is dead. Except! If you’re using a rechargeable battery like a lithium-ion, you can reverse the process. If you dump energy into a circuit using a charger, you can force the reaction to go in the other direction and get that electron party at the anode all crowded again. Once your battery is recharged, it’ll mostly stay that way until there’s something for it to power again, though all batteries leak some charge over time .


What determines the capacity of the battery—how long it can power your stuff—is the number of lithium ions that can nestle themselves into the tiny, porous craters of the anode or the cathode. Over time, with repeated charge the anode and the cathode degrade, and can’t fit as many ions as they used to. As that happens, the battery stops holding a charge as well as it once did.
How does a lithium-ion battery recharge?

It’s easy to think of charging a battery as though you’re filling a tub with “power.” Just hook up the hose until it’s full! From the outside, that’s exactly how it works, but on the inside it’s a little more nuanced.


A lithium-ion battery typically charges in two stages. First comes the process called constant current charging. This is the part that really is pretty simple. The charger for your phone or tablet will apply a steady current of electricity to the battery to get all those electrons back to the anode. During this stage, the charger just decides how much power is coming out of the firehose and starts spraying. The higher that constant current, the faster the battery can charge. High-voltage quick chargers—like the ones that are starting to come with a lot of new phones—take advantage of this first stage to cram in the juice as quickly as possible (at the cost of a bit of extra stress on the battery).


When the battery is 70 percent recharged, the procedure changes and flips over to constant voltage charging. During this second stage, the charger makes sure that the voltage—that is, the difference in current between the battery and the charger—stays the same rather than keeping the current constant. Practically, this means that as the battery gets closer to full, the current the charger sends into it decreases. As the battery gets full, the rate at which it charges slows down. Once you reach 100 percent, the charge simply trickles in, just enough to account for the tiny, tiny bit of charge your battery loses naturally over time.


So what about over charging? al writer for iFixit, who explained why.
All modern Li-Ion rechargeable devices have some sort of power management IC, designed to prevent overcharging the battery. They’ll keep your phone battery topped off and ready to go throughout the night with a trickle charge at most.


No matter how many times you bring it back to life, your battery will die someday, or at least degrade into a shadow of its former self. That’s unavoidable. Most lithium-ion batteries have a rated lifetime of somewhere between 500 and 1,500 charge cycles .
One cycle is just one bout of discharging, but how much energy you discharge in one go—a measure referred to as depth of discharge (DoD)—matters bigtime. Lithium-ions really hate a deep depth of discharge. According to Battery University, a staggeringly exhaustive resource on the topic, a li-ion that goes through 100 percent DoD (the user runs it down all the way to zero before recharging) can degrade to 70 percent of its original capacity in 300-500 cycles. With a DoD of 25 percent, where the user plugs it in as soon as it gets to 75 percent remain, that same battery could be charged up to 2,500 times before it starts to seriously degrade.


What’s far more dangerous to a battery’s well-being is heat. Lithium-ion batteries despise heat. A li-ion battery that’s been exposed to temperatures of around 100 degrees Fahrenheit for a year will lose about 40 percent of its overall charge capacity. 75 degrees, it’ll lose only about 20 percent.
Something that’s not an issue is overcharging. Contrary to what you might think (or have been told), leaving your phone or laptop plugged in all the time is not bad for its battery. That’s because your gadgets, the batteries in them, and the chargers you attach them to are actually pretty smart about the way they do business.

Trickle charge—what your battery gets when it’s connected and full—is way less distress to the battery’s health than a larger discharge would be.

Simple Tips To Preserve iPhone 14 And iPhone 14 Pro Battery Health

Planning to keep your iPhone 14, iPhone 14 Plus, iPhone Pro, or Pro Max for a long time?Here are some tips to preserve battery health.
If you’re planning to keep your iPhone 14 or iPhone 14 Pro for a long period of time, you should preserve its battery health by following some basic tips

The internet is on fire right now with iPhone 15 related news. A lot of people are going to upgrade, while some may not later this year. If you are from the latter group and plan to keep your iPhone 14 or iPhone 14 Pro for an extended period of time, maybe two to three years, then I am going to share some tips on how to preserve battery health so that you get the most out of your phone’s battery while it’s in your ownership.

Use original or Apple certified accessories to charge up
This is the most obvious thing you should do while charging up your iPhone 14 or iPhone 14 Pro. Use the cable that came with your phone, or if you’re using a third-party one, make sure it’s MFi certified – just look for the ‘Made for iPhone’ badge, and you’re good to go.


Also, make sure that you’re either using a wall charger made by Apple or something that’s high quality, if going for a third-party one. A quick search on the internet will list down a number of chargers that are made with high- quality materials and circuitry. A bad charger is all you need to ruin your iPhone and its battery instantly. Just spend the extra money and get a charger that will last you an eternity. Great chargers are extremely hard to break down, and if they do , they will never ever damage the connected device.


Stop worrying about charge cyclesSmartphone batteries are usually good for up to 500 charge cycles before hitting the 80% health mark. But that charge cycle number is absolutely useless if your usage habits are terrible. I’ve seen MacBook Pro laptops with just 15 charge cycles at 90% battery health. How? Because they were left on charge and at 100% at all times.
On the other end of the spectrum, you may come across a device with more than 100 charge cycles with 100% battery health because they were used carefully. Now read further about how you too can be careful with your iPhone’s battery health.


Use a fast charger or a slow one, it’s up to youFast chargers won’t hurt your battery as long as the ambient temperature is low and the phone does not get too hot. If you constantly find yourself in a situation where your iPhone gets hot while charging, just use a slow charger that tops out at 12W. Anything that does not generate too much heat is good for battery health.
Use the 40-80 rule – but carefullyPeople swear by this rule, and I have tried it as well. Does it work? Only if you thoroughly respect how it works. If you don’t, you’ll end up losing battery health.

I’m not going to take a deep dive into how Lithium-ion batteries work because a lot of people have done it already. But I’m going to tell you that keeping your charge level extremely high or extremely low is going to take a toll on your battery health.

So, if you’re going to maintain a charge between the 40% and 80% mark, make sure you drain the battery all the way from 80 to 40 before charging up again to 80. Don’t hold the charge at 80%, and do not hold it at 40%, either.
If you’re doing what I wrote above, you’ll see how your battery health remains steady for a long time. Now the part that no one talks about when it comes to this rule – is awful battery life. While you’re busy maintaining battery life between 40% and 80%, there’s 40% of the total battery life you’re never ever going to use, which will give you the illusion of horrible battery life on your iPhone. That’s completely normal.


Making the battery drop to 20% or maybe even lower occasionally is not bad for the battery either. There are certain things that aren’t in our control – for example, you’re away from a power outlet or don’t have access to a power bank. In those cases, it’s fine to let the battery slide down a little until you can take things back into your own hands.


Use Optimized Battery ChargingWhile everyone out there will go deep into the science of how optimized charging works, but I’ll make things easier by telling you that your iPhone’s battery won’t charge beyond the 80% mark unless the battery cools down. Therefore make sure the feature is turned on.
You can do this by going to Settings > Battery > Battery Health & Charging and turning the Optimized Battery Charging option on.

Keeping the feature turned off means the iPhone will charge all the way to 100% without any sort of pauses in between. That’s simply not good for battery health at all.


Do not use your iPhone while charging (obviously)Anything that generates heat is going to hurt battery health. If you’re using your iPhone while charging, you’re generating excess heat that will not only affect battery performance, but battery health, too. When you put your iPhone on a charge, make sure your iPhone is never ever used during the charging cycle. Avoid using it completely if you can.


While charging, remove the case for better dissipation of heat. A chunky case might be great for protecting your phone, but it will generate a lot of heat, especially if you’re wirelessly charging.
Avoid wireless chargers in hot weatherSpeaking of wireless charging, if you can avoid it completely, that’s great. But, if you’re charging in a room that’s cool, especially air-conditioned, then it’s fine. Also, make sure that the iPhone’s case comes off while going ahead with wireless charging. While it’s a convenient feature, wireless chargers generate way too much heat compared to wired charging.

If possible, I will highly recommend using wired charging while on the go, especially during summer. Sure, slapping on that MagSafe Battery Pack will charge you up, but it comes at a cost which you will see expensive on the battery health report page, eventually.


Wait for your iPhone to cool down before using itIf you feel that your iPhone is too hot, quite literally, do not start using it immediately. This is extremely important when you take your iPhone off the charger or are planning to put it on charge. Let the iPhone sit around for a while so that it reaches normal temperature – should not feel hot to the touch – and then start using it or place it on charge.


ThoughiPhone batteries are made to resist high temperatures, that does not mean they will stay forever perfect in the battery health department. Extreme temperatures are your iPhone’s worst enemy.

How an iPhone battery works and how to manage battery health

Your iPhone uses a lithium-ion battery that degrades over time, but there is little reason to worry about battery health in a new device. Here’s what you need to know about your iPhone’s battery.

Batteries are not mysterious black boxes that power your iPhone, in fact, they are quite simple products compared to the advanced silicon they are powering. The physical nature of batteries mean that they will ultimately wear out and become less useful over time, but device owners don’t need to worry.


Understanding a little bit of the science behind batteries can go a long way in intelligently managing your device’s lifespan. Controversies surrounding iPhone relating to planned obsolescence and expected upgrade cycles can easily be dismissed as hyperbole with a little bit of knowledge.


Lithium-ion battery basicsA battery consists of an anode (+) and cathode (-) separated by a generally flammable electrolyte. When a device draws power from the battery, charged lithium ions move from the anode to the cathode through the electrolyte, releasing electrons.


These freed electrons power the device and return to the cathode, creating a complete electrical circuit. The opposite occurs when charging the device — electrons are passed into the anode and move to the cathode.


Without getting too technical, these two chemical reactions are imperfect and introduce heat loss and wear to the battery. The lithium material slowly depletes, oxidization reduces usable surface area, and filaThin phones mean smaller batteries, which become exhausted soonerThere is nothing a user can do to stop this process desolately. Take using fuel in a car, for example, it eventually runs out. However, exhausting a lithium battery takes a great deal of time and can be mitigated somewhat by user and software behaviors .


So, when a new iPhone has a 100% battery rating, it has all of the rated milliamp-hours of power available when fully charged. It also means the battery can provide enough power to the CPU at peak current draw without issue.
Apple says its batteries are designed to retain up to 80% of their original capacity at 500 complete charge cycles. A charge cycle is defined by a complete drain of the battery to zero, followed by a complete charge to 100%.


This expected battery life can vary from user to user. The average user is expected to keep their battery health north of 80% for the first two years with regular use. Hitting 80% within a year is cause for concern, and Apple will replace your battery for free with AppleCare or for a fee without.
Others who use their iPhone constantly and charge their device from near dead to 100% multiple times a day will see their battery degrade faster. Looking at your Screen Time will reveal if you’re unconsciously overusing your device — maybe it’s time to put down your iPhone if TikTok shows multiple hours of use in a short time.


Of course, iPhones are bought to be used. But, like anything, moderation is important, especially if you’re worried about something as physical as battery chemistry.
Ultimately, once the battery degrades below 80% of its original capacity, protections within the operating system will engage to ensure the device doesn’t shut down inadvertently.

This throttling can be avoided by having the battery replaced at an Authorized Apple Service Provider.
After the iPhone throttles the processor for the first time to prevent a shutdown, a new toggle will appear in battery settings. This gives users the ability to turn off the throttling feature and allows the processor to draw full current.
However, the device will shut off as soon as the current draw exceeds what the battery can provide. It is highly unadvisable to turn off the throttling feature and can lead to battery damage.


Degraded batteriesBefore iOS 10.2.1 in 2017, the iPhone didn’t do much to account for aging batteries in its software. However, a perfect storm of circumstances set Apple up for user complaints about inadvertent shutdowns in older devices.
Recent devices had more powerful processors, thinner designs, and brighter displays. These factors led to smaller batteries with lower capacities that died faster. A smaller battery also meant a lower peak voltage, which meant aging batteries would dip below peak rated voltages sooner.


Those factors were coupled with more people buying iPhones than ever, then keeping them for longer than expected, which led to more reports of batteries becoming exhausted. Note that the “Plus” models and iPads were not encountering shutdown issues thanks to their larger battery capacities .Lithium-ion can’t provide peak voltage at lower charges, which gets worse with ageIntermittent shutdowns were reported by owners of the iPhone 6, iPhone 6s, and iPhone SE. 

Users complained that the device would show battery levels of 30% or more  then suddenly shut off as if the battery died.
This occurred because these devices’ batteries had been exhausted to the point that they could no longer provide peak power during peak CPU draw. Since there were no other protections in place, the iPhone would sense the CPU power draw exceeding the available current and just shut down to protect the battery.


The iOS 10.2.1 and subsequent updates created safeguards that throttle the CPU based on the device’s remaining battery health. Fresh batteries above 80% health will never encounter this CPU throttling feature.Apple hadn’t considered its need until widespread reports of shutdowns began.
