Do cell phone batteries contain protection circuits?

I have dozens of old cell phone batteries that I would like to try to repurpose. I googled the answer but didn’t find anything consistent.
You can buy lithium polymer batteries for DIY purposes from places like SparkFun that come with a PCB protection circuit attached to the battery.

Do these types of cell phone batteries contain circuitry similar to the one on the green PCB, or is it the circuitry inside the phone?

If so, is the best way to just use a charge management IC like the MCP73831 for charging? If not, how can these cells be practically utilized? The Apple mobile phone battery also has three or four pins, two of which are obviously power + and -, and the other two are status indicators? What exactly are these other two pins used for? What is the best way to handle these batteries when using them in a hobbyist DIY environment?


EDIT Also, I only want to use the battery for low current purposes (a few hundred milliamps max) and most of them are from unused phones.
These batteries do have built-in protection, but not the kind you see on Sparkfun batteries. They have thermal protection required for battery charging and sometimes a low-battery cutoff to prevent over-discharging of the battery. However, there is no overcurrent protection , overvoltage protection, or protection against novice abuse…
You have two pins for + and – (simple) and a temperature pin to detect if the temperature rise is at normal levels. This ensures that the battery will not explode while charging. In practice, you read this as a variable resistor.

This feature isn’t used very often as they usually try to maximize battery capacity, especially with modern smartphones, but it’s not uncommon for older, not-so-smart flip phones like mine 🙂
Obviously, charging a lithium polymer battery is a risky thing to do without the correct settings. Disclaimer: I do not recommend charging your battery without an approved charger.


Having said that, one can charge it using any LiPo-compatible charger. Cell phone batteries usually only have one cell, so charging them is very easy. It should check the battery voltage and divide it by 3.5 to 4. This will indicate the number of cells connected in series. Then use an unbalanced charger to charge the battery to the appropriate level. If charging for the first time, assume you need to use a multimeter to check whether the battery is getting hot via a remote circuit., additionally one may want to do this outdoors where a fire or explosion in the battery won’t harm anyone around it.
Seriously, just throw them in the recycling bin at your nearest electronics store. It’s safer. You can buy LiPO cheaply for about $30 at some RC hobby stores like Hobby King or any store with an approved charger. It’s really not worth the risk of injury Also, if those batterieswere removed from the phone, they’d probably have reached the end of their actual useful life, so…

Complete the question about managing the IC: Basically, yes, you can use it. It looks like it can charge up to 500mA, which is typical for iPhone cell phone batteries. BUT…make sure your IC is configured to charge at the correct voltage level, this may end up being a trial and error process as not all cells are created at the exact same target voltage. If I were you, I would charge to one of the lower options first (4.35V or 4.4V max) and limit charging to 7.5%-10% for the first option.

If everything goes well and the battery isn’t overheating, you can try other settings. If it seems hot, return to a lower setting. I’ve seen a lithium polymer battery overcharged and while it didn’t explode, gas would form and the battery would expand slightly. If you notice the battery is swollen, disconnect the power source and discard the battery. If you’re very careful and know what you’re doing, it seems fine.


I would try to buy an unsold cell phone and wall power supply. It’s better to use your mobile phone as a charger. As a result, you eliminate any mechanical issues, contact is near perfect, and you’re certain you won’t burn fat. As a bonus, if the lipo is still charging, you get a pretty reasonable display. I’ve been using an old Nokia 3310 for two years now and I’m happy with this solution.And it is an excellent question – how to practically use them?


The first and simplest method is to make use of the separate battery charger that comes with the phone – these are very common in Korea, and from what I see, people use them more often than in other places – in other words, actually popping it out and flipping between a charged and uncharged battery.


(Cultural note: Korea has a long tradition of people opening and removing their smartphone battery during the day to swap in a new one, then charging the other. This is why Korean customers expect to get two batteries when they buy a phone, although this is decreasingly common with non-removable batteries in the newer phones. This tradition began in the time of the Chosun dynasty, more specifically, Sejong the Great. Many historians note that he may have had a Nokia 1011, but for understandable reasons, most Korean historians vehemently deny this.)

The great thing about these chargers is the quality circuity inside that can safely charge almost any three-pin 3.7 battery of any size. I say three pins, because these charger boards will not start until they detect the temperature pin connected.

This narrows them to use for cellphone batteries only, but if you have a drawer full of them, then this is a great device. For flexibility, soldering on three color-coded wires to the battery terminals of each battery, plus three to the cellphone charger makes it very easy to swap  iphone cell phone batteries in and out.

Signs That Your Phone’s Battery Needs to Be Replaced

Do you notice your phone running out of battery faster than usual? 

If you’re charging your phone numerous times per day it’s a clear indication that your battery has lost its efficiency and you need to find a battery replacement as soon as possible. 
It’s true that even if you put an effort to take care of your smartphone batteries, they all have a limited lifespan and will eventually lose their function to work properly. Because of daily usage and the use of lithium-ion, it only means that you will eventually need to have it replaced. 


But don’t fret because there are a lot of options to choose from for different phone brands. In this blog, we will show you what to look for and how to replace a new battery for your Apple model Cell Phone batteriesHow to Check Your Battery’s HealthThere are different ways to check your battery’s health for both Android and iOS users including the following: 
For Android
Enter *#*#4636#*#* into the phone app and press enter. This will bring up a “Testing” menu with a section for “Battery information” in it. Here you’ll be able to examine the state of the battery.

Go to “Settings” and open the “Battery” section. Inside, you’ll get an overview of the apps that are using your battery. You also have the option to tap “Battery Health” to know more about your battery’s capacity and if it needs to be repaired. 
You Need A Battery Replacement When:Battery is Overheating
Temperatures between 68-86 degrees Fahrenheit are suggested for smartphone batteries. It can operate outside of this range, but it will reduce the battery’s overall life and it is a sign that your battery will need a replacement soon.
The Battery Quickly Runs Out of Power


On a full charge, new iPhone smartphone batteries should last anywhere from five to eight hours on average. On the other hand, it may be on its last few cycles if it lasts only two to three hours after being fully charged. The same can be said for gadgets that suddenly declined by 10% or 20% the instant they’re disconnected.
The Phone Won’t Turn On
The smartphone’s inability to turn on is one of the most evident indications of a dead  battery . It’s time for a new battery if the current one isn’t enough to power the device. However, there are times that other parts of your phone such as your charger or screen may be the culprit. It’s best to bring your phone to the nearest service center for a check-up. 


Your smartphone’s battery health has most certainly degraded severely if it goes off at a rate of 30 percent or even 50 percent. A typical indicator is a boot loop. It’s mainly due to an aging lithium-ion battery if you have an older smartphone that restarts continuously after reaching a particular battery level.


Before You Replace the Battery, There Are a Few Things to ConsiderAlthough battery changes are extremely beneficial, they can also be time-consuming. For example, getting work done on your car. You may be able to do it yourself, but it’s probably easier to pay someone else to do it for you, and you should expect to be without your phone for a bit while the repair is being completed.


As long as the battery for your gadget is in stock, many places offer same-day repairs. That is, if you’re looking for a repair shop with a real location near you. If you live near any service center, you might be able to find what you’re looking for. However, you may have to send your phone in for a repair, which could leave you without it for days. 
ConclusionIf you’ve owned your phone for a few years and it’s starting to show signs of wear and tear, it’s probably time to change the battery.

Many carriers still offer upgrades or payment plans that renew every two years to tempt you into upgrading–but you can also check your iphone battery’s condition manually if you want to determine if you need an upgrade sooner rather than later.

Tips on Charging Your Phone to Maximize Battery Life and Lifespan

Everyone knows that cell phones have to be charged regularly in order to keep working,but did you know that the way you charge your phone has an impact on how long the battery lasts? It’s true. Simple things like over and under-charging can actually shorten the life of your apple cell phone battery . The good news is you can keep your battery going strong by following a few basic rules. Here are our top tips for charging your cell phone properly.

What is a Cell Phone Battery Charge Cycle?Most cell phones today run on lithium-ion batteries. 

Lithium-ion batteries work in charge cycles. You complete one full charge cycle when you’ve used (or discharged) an amount of power equal to 100% of your battery capacity. If you use 75% of your battery’s capacity on Monday, then recharge it fully overnight and use 25% of its battery capacity the next day, your total usage for the two days will add up to one full charge cycle.


The life cycle of your cell phone battery is also measured in charge cycles. A new lithium-ion battery will typically last between 300 and 500 charge cycles. This is where your charging habits come into play. Usually, a cell phone battery lasts between two and three years, although the frequency with which you charge it plays an important role in how quickly you burn through those cycles.


What is the Correct Way to Charge a Phone?

Follow these basic tips to make your charge cycles last longer and get the longest life possible from your battery.
1. Don’t Charge Your Cell Phone OvernightWhen you keep your phone plugged in overnight, you’re keeping it on the charger for much longer than is needed. If a battery becomes overcharged, it can become damaged. In order to prevent this, your cell phone will start to discharge the battery slightly. Then, after the charge drops too low again, it will begin to charge it back up again. This constant cycle of discharging and recharging causes your battery to burn through its total number of charge cycles much faster, shortening the battery’s overall life.


2. Don’t Charge Your Cell Phone to 100%While it sounds counter-intuitive, continuously charging your cell phone battery all the way to 100% is something you should avoid. A battery that contains a higher voltage is placed under more stress than one running at a mid-range capacity of 40% to 80% state of charge. This stress can degrade the battery by wearing down its internal chemistry. Ideally, you should only charge your cell phone to 100% if you intend to remove the phone from its charger and begin using it within a few hours.


3. Don’t Let Your Cell Phone Battery Drop Down to ZeroWhile overcharging is a problem, letting your cell phone battery run down all the way is also not good. Some people might tell you that your battery will lose part of its total capacity unless you run it down to zero. This is false. While it is true that nickel-cadmium batteries possess this “memory effect,” the lithium-ion batteries in your phone function quite differently. Discharging a lithium-ion battery completely can actually diminish its overall capacity, so it’s best to always keep it charged to 40 -80% of its total capacity.


4. Don’t Let Your Cell Phone Get Too HotAccording to the Apple website , cell phones and other devices are “designed to perform well in a wide range of ambient temperatures, with 62° to 75℉ (16° to 22°C) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 95℉ (35℃), which can permanently damage  Apple battery capacity.”


Exposing your cell phone to high heat on a regular basis can impair the battery’s ability to hold a charge. Remember how we mentioned that keeping your phone at 100% capacity puts it under increased stress?

Well, those stresses are magnified even further by extreme heat That’s why it’s important to avoid charging a cell phone in high temperatures. If you notice that your phone has gotten excessively hot, there are a number of steps you can take to cool off your phone.
How Can I Tell if My Phone Battery is Dying?On average, a cell phone battery should last between two and three years. After that, it will likely begin to have a negative impact on your cell phone’s performance. Here are a few common symptoms of a dying cell phone battery:
Needing to charge your phone multiple times in one dayThe phone won’t charge completelyPhone charge drops immediately after being removed from the chargerBattery drains too quicklyPhone randomly crashesYou notice a slower performance from your iPhone

Which iPhone Has the Best Battery Life?

In addition to several factors such as storage capacity, many buyers also consider battery life when purchasing a phone, and for good reason. Imagine you enjoy using your phone for hours only to find that it dies after a few hours of use. Having a phone with poor battery life can be frustrating, especially for iPhone users.


Apple has significantly changed the range’s features, including  Apple battery life. So if you’re wondering which iPhone has the best battery life for your next upgrade, you’ve come to the right place.
In this article, we’ll affect take a look at the iPhone models with the best battery life, as well as factors that battery life and tips closer for improving battery health.
10 iPhones with the Longest Battery LifeAs Apple releases new versions of its iPhone lineup, it significantly upgrades several features, including battery life. Measuring a phone’s battery life is difficult because there are many factors that affect a phone’s battery life. But it can still be judged by audio and video playback , standby time before charging, battery capacity, usage time and other indicators.


In this section, you’ll see a list detailing which iPhone has the longest battery life, more information about its battery capacity, and a brief description of its features.
First place: iPhone 14 Pro Max – 13 hours, 7 minutesiPhone 14 Pro Max battery lifeThe iPhone model with the longest battery life is the iPhone 14 Pro Max. Its battery lasts for 95 hours of audio playback, which means you can play music on your phone all day long. It can also play 29 hours of video and 25 hours of streaming, perfect for long movie nights.


The iPhone 14 Pro Max also features a 6.7-inch 120Hz display with an “always-on” option and a 48MP camera, perfect for taking photos and videos. It also has a new feature called Dynamic Island, which gives you a snapshot of your phone’s activity.
Second place: iPhone 13 Pro Max – 12 hours, 16 minutes Even before the 2022 iPhone 14 was released, many iOS users praised the iPhone 13 Pro Max for its large battery capacity that lasted for hours. The battery life of the iPhone 13 Pro Max is still comparable to newer models.
It can play videos for up to 28 hours, which is not much different from the iPhone 14 Pro Max. It also has a scratch-resistant, Super Retina display, which makes this model perfect for streaming and gaming.

Update to the latest software.
Be sure to install the latest iOS version for your iPhone when it is available for your device. If your phone has an iOS update available, plug it into the charger and use Wi-Fi or mobile data to update. Alternatively, you can plug your iPhone into your computer and update using iTunes.
Optimize your settings.
No matter how you use your device, two of the easiest ways to save battery life on your phone are to adjust the screen brightness and use Wi-Fi instead of mobile data, as it uses more battery than Wi-Fi. To adjust your phone’s screen brightness, dim the screen or enable auto-brightness.


Avoid extreme ambient temperatures.
Make sure to avoid exposing your iPhone to temperatures above 35° C (or 95° F), as storing the device in hot environments can permanently damage its battery and affect its ability to charge. Avoid charging your iPhone in hot places as this may further damage your device.

Remove some cases while charging.
Charging your device may generate excessive heat under certain circumstances. This heat can negatively affect yourApple Cell Phone battery capacity and shorten its life. To prevent this, remove your phone from its case before charging.
Enable low power mode.


Low Power Mode allows your phone to extend battery life when it drops to 20% or again to 10%. When enabled, this feature reduces brightness and disables background processes. It will turn off after the phone is charged. You can enable it through Settings > Battery or by turning it on when prompted.
View battery usage information.
Managing your iPhone’s battery life is easy because iOS gives you insights into which apps are draining the most power. To check your phone’s battery usage, open Settings > Battery. Once you enable this setting, you’ll see different information, such as when your phone was last charged and a graph showing battery level and activity over time.
Please keep it half-charged for long-term storage.
If you plan to store your device for an extended period of time, be sure to charge it to 50% first. Fully discharging your phone’s battery can cause it to fall into a deeply discharged state, meaning it can no longer be charged.What can quickly destroy the health of your iPhone battery?The main factors that can quickly damage the health of your iPhone battery are exposure to high temperatures, battery levels dropping to 0%, frequent overcharging, and battery age. However, it is difficultich means more stable photos. It is also available in various colors such as yellow, red, and purple.

How to see battery charge percent on your iPhone

To make room for the Face ID notch, Apple removed the old battery percentage number from the iPhone home screen . But there are still ways to get this useful information when you need it.


The battery icon in the upper right corner of your iPhone screen can be very useful in a pinch. For example, it will tell you whether your phone is fully charged, so you can rest assured. Or in a more common case, it will show you that the iphone battery is about to run out. It’s just that between those two extremes, it’s not that useful – it’s not nearly as helpful as a charge percentage number. 
Of course, you can’t tell from the icon whether the battery is dropping unusually quickly. Instead, it’s important to be able to see that you’ve improved from 100% to 95% the moment you walk out the door.


When we got the Face ID notch on the iPhone X, we lost   Apple battery percentage and all status icons were pushed to the left or right. You’ll notice that the iPad and iPad Pro retain the percentage numbers, but that’s because they don’t lose devices like the iPhone X, iPhone XR, iPhone XS, iPhone XS Max, iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max About half of the top area. Rumors suggest we’ll see a smaller notch in 2020’s “iPhone 12 ,” which could lead Apple to give us that percentage number again .

For now, though, it’s hard to argue that Apple was wrong to ditch that percentage given the smaller space available, since it does retain the battery icon, as well as Wi-Fi and cellular data. We won’t swap the last two, but it would be better to replace the battery icon with a percentage.
However, you can still find out the exact percentage of charges if needed. There are several ways to do this, and if none are more convenient than simply glancing at the top of your iPhone screen, then one of these methods will work for you.
Use control centerDepending on what you’re currently doing with your phone, in most cases the fastest way to check your battery level is through Control Center.
Battery charge percentage is always located in the upper right corner of Control Center
Swipe down from the top right corner to launch Control CenterRead the battery percentage in the upper right cornerThat’s it. No matter what app you are using, or even if you are not in the app, you can call up Control Center and read the percentage instantly.


Use notification centerSetup is required the first time you do this, but thereafter the battery level will be listed in your iPhone’s Notification Center. If you use this feature frequently, it might even be faster than going through Control Center.
Plus, it might also be more convenient, since the Notification Center version not only shows the battery level in your iPhone, but also lists your Apple Watch. It will also show your AirPods’ charge level if they’re connected and removed from the charging case or the lid of the charging case is open.
To set it up for the first time, do the following, starting on your iPhone’s first Home screen or Lock screen.


Swipe left to enter the notification centerScroll all the way down to the bottom and click “Edit”Scroll down to the “More widgets” sectionFind the battery and click the green plus sign next to itThis will move the battery to the top area, which is the list of widgets shown in Notification Center. This is also a list showing the order in which they appear. So if you want to see the battery level at the top, do that.
Click on the handle to the right of the battery (three horizontal bars)Drag up to rearrangerelease when it’s in placeFinally, click “Done” to finish editing the widget.

Now that you’re set up to use Notification Center to show all your battery percentages, feel free to do the following when you want to know exactly how much power you have left.
Swipe left from the lock screen or first home screenRead cost percentageSwipe right to close notification centerTell you with SiriYou can also ask Siri at any time.
There are different ways to say it, but “Hey, Siri, how much battery do I have left?” always works.
You can also ask Siri on your iPhone to tell you how much battery is left in your Apple Watch. However, you can’t ask Siri on the Watch to tell you how muchApple Cell Phone  replacement battery is left on your Apple Watch.
Quick view while chargingIf you have a Qi wireless charger nearby, place your iPhone on it. Your iPhone’s lock screen displays the current battery percentage.
If you just plug your iPhone into the charger, it will do the same thing, but in both cases it will only briefly display the percentage.
Your iPhone briefly displays battery percentage when you put it on charge (left) or take it off again (right)


If you don’t notice in time, though, you can remove your iPhone from the charger, which will briefly display the battery percentage again.
There is another wayFor absolute completeness, we also tell you that you can create your own shortcut to display The same goes for fee percentages.
This is a particularly simple shortcut to create and display the percentage as a regular notification. This can be convenient as the notification can remain on your screen until you choose to dismiss it.


Plus, you can do more with the content you find using shortcuts. By default, your iPhone prompts you to enter low-power mode when it reaches 20%, but maybe you know that won’t get you through the rest of your day. You can create a shortcut that, whenever you run it, checks the battery and gives you the same low-power mode if it’s below 50%. In this case, you must actively choose to perform certain actions in order to find out your battery percentage . This will never be as convenient as browsing, but it seems unlikely that Apple will bring back this option anytime soon.


However, there is one thing. When Apple does offer the option to display battery percentage, it’s easy to get anxious about it. You can keep picking up the phone to check the battery level, but of course, this action will cause the battery level to drop. So even though you can now use all these different methods to find out your Apple batterypercentage, maybe you should avoid doing it too often.

How to make your iPhone battery last longer

Every time a new iOS update is released, many users inevitably experience rapid depletion of battery life. The latest iOS 16 is not immune to this issue, which is largely due to background processes like syncing and indexing that are beyond user control. While some of the reasons for rapid battery life depletion can be found in various articles, the problem sometimes persists longer than expected.


In situations where extending battery life is crucial, such as when traveling, it’s important to know how to optimize your iPhone’s settings. MacRumors has some tips to help extend battery life in iOS 16 without disabling most of its major features. Remember, finding the right balance between turning certain features off and on is key to ensuring longer battery life.


Tips and Tricks to Extend apple smartphone battery Life1. Disabling keyboard tactile feedback can extend iPhone battery lifeTurning off the keyboard’s tactile feedback can save some battery life. Because it eliminates the need for your device to provide vibration or tactile feedback while typing
Apple’s recently released iOS 16 update has a new feature. This is tactile feedback when using the on-screen keyboard. However, this feature consumes a lot of battery power. Apple provided a support document indicating that keyboard touch may affect battery life. Note that this feature is not enabled by default. If you have it turned on and want to disable it, follow the steps below. First, open the Settings app on your device. Then, click on the Sound & Touch option. After that, click on Keyboard Feedback. Finally, you can disable the haptic feedback option to save Apple’s battery life.
2. Turn off live activity to give your iPhone battery life longerDisabling real-time activities, such as live wallpapers and other dynamic content, can reduce battery stress.
iOS 16 battery
Apple’s iOS 16.1 update introduces a new feature called Live Activities. The feature enables apps to receive continuous and updated notifications on iPhone 14 Pro’s Lock screen or dynamic island. However, you can disable this feature if you’re concerned about extending battery life.
To disable live activity, you need to follow a few simple steps. First, open the Settings app on your iPhone. Then, navigate to the Face ID & Passcode section and enter your passcode to unlock your device. Once you have done this, scroll down until you see the Live Activity option and toggle it off.


If you want to disable live activity for a specific app, you can do so by going to each app’s settings and turning off the feature individually. It’s worth noting that while live activity can be disabled, you can’t disable dynamic islands entirely. However, you can swipe left on any running animation to turn it off and further save battery life.
3. Delete lock screen widgetsRemoving widgets from the lock screen can help save battery life by reducing the number of processes running in the background.

Widgets are a useful feature on iOS devices that allow users to quickly access information and perform tasks without opening an app. These widgets can be added to the lock screen and home screen for easy access. However, it’s worth noting that widgets drain battery power. Especially if they are constantly updating in the background.
If you find yourself needing to save battery life, it might be a good idea to create a lock screen that doesn’t contain any widgets. This can be done easily on iOS 16, as the update now supports multiple lock screens that can be easily switched. This way, you can have a lock screen with widgets when you need them, and a more battery-efficient lock screen when you don’t.


Also note that widgets may appear on the home screen. This is a feature that existed before iOS 16. However, using widgets on the home screen can also drain your battery. Therefore, if you want to save battery life, we recommend not using widgets on your home screen.
4. Turning off “Always-On Display” can make your Cell Phone battery last longerWhile the always-on display feature is convenient, it also drains battery life. Turning it off helps save energy.

The iPhone 14 Pro and Pro Max have a new feature called Always On Display. This feature is designed to keep the screen on, even when the device is turned off. This means users can still see their wallpapers, widgets, and live activity on the lock screen without having to unlock the device.


5. Do not use ICLOUD to share photo librariesSharing your photo library using iCloud may cause your devices to constantly sync, causing your battery to drain quickly. If possible, avoid using this feature.

iCloud Shared Photo Library is a feature in iOS 16.1 that allows users to share photosir photo gallery for up to five other people. This means that all members of a shared library can upload, edit, and delete photos stored in the library. But it’s important to note that using this feature may cause other members’ photos to sync to your iPhone at inappropriate times, draining youriPhone’s battery life.

Apple Is Locking iPhone Batteries to Discourage Repair

By activating the hibernation software lock on the latest iPhones, Apple is effectively announcing a major new policy: Only Apple batteries can be installed in iPhones, and only they can.
If you replace the battery in a recent iPhone, a message will appear next to Battery Health in Settings > Battery indicating that the battery needs service. A “service” message usually indicates that the battery has degraded and needs to be replaced. However, when you put in a brand new battery, the message will still appear. The bigger problem: Our lab testing confirmed that even if you replace the original Apple battery, the phone will still display a “Service” message.


Update: Apple now pairs the screen with the iPhone logic board, too.
This is not a mistake; This is a feature Apple wants. Unless the Apple phone’s battery is verified by Apple Genius or an Apple Authorized Service Provider, the phone will never display its battery health and will always report vague, ominous issues.


Screenshot of the Service message in iPhone battery health settings.
We first saw this phenomenon in a video from The Art of Repair’s Justin, and we were able to replicate it on an iPhone XS running iOS 12 and iOS 13 beta. Replacing a new genuine Apple battery from another iPhone It said that currently this only affects iPhone XR, XS and XS Max.


In short, Apple locks the battery into the iPhone at the factory, so whenever you replace the battery yourself (even if you’re using an original Apple battery from another iPhone), it will still show you the “Service” message . The only way to fix this problem is to (you guessed it) pay Apple to replace your iPhone battery. Presumably their internal diagnostic software flips the magic bit that resets this “service” indicator. But Apple refuses to make the software available to anyone but themselves and Apple Authorized Service Providers.


Our friend Justin pointed out that the battery itself has a Texas Instruments microcontroller that provides information to the iPhone such as battery capacity, temperature, and the time it takes to fully discharge. Apple uses its own proprietary version, but nearly all smartphone batteries have some version of this chip. The chip used in the new iPhone’s battery contains an authentication feature that stores information about the battery’s pairing with the iPhone’s logic board. Simply put, if the battery does not have the unique authentication key that the iPhone’s logic board expects, you will receive a “Service” message.


Documentation for the TI microcontroller responsible for locking the iPhone battery.
This is a bad choice for usersJust because a silicon part has a certain function doesn’t mean Apple has to use it. For years, iPod audio chipsets included AM/FM functionality that Apple never used. This Service light is the equivalent of the Check Oil light, and only your Ford dealer can reset this light, even if you change the oil yourself.
Technically, it is possible to restore battery health functionality by removing the microcontroller chip from the original battery and carefully soldering it into the new battery you are replacing, but the process is not for the faint of heart, and it is Unreasonable request for any repair , let alone something as simple as replacing the battery.
Fortunately, your replacement battery will continue to work perfectly, and you’ll get all the benefits of a new battery – for example, we’ve confirmed that this won’t limit your iPhone’s performance on a healthy battery. But you won’t be able to easily see the health of your battery and know when it’s time to replace it.


Then again, this is a big problem for iPhone users, who may not be aware of this new, sneaky lock, which will undoubtedly cause confusion: they’ll replace their own batteries and notice the “Service” message, and then Starting to solve the problem is not there.
Apple is hiding your battery’s health dataTo make matters worse, starting with iOS 10, Apple has blocked third-party   Apple Cell Phone batteryhealth apps from accessing most of your battery’s details, including cycle count, which is key information that tells you whether your battery is on the verge of degradation. However, you can fix this problem by plugging your iPhone into your Mac and installing a Mac app like Coconut Battery. Even if your iPhone refuses to show this information in settings, it will display battery health statistics.
This is an ongoing trend and Apple is making repairs increasingly difficult. Back in 2016, they completely bricked previously repaired iPhones, showing an opaque “Error 53” if you replaced the Touch ID home button because they were paired to the motherboard. In fact, DIY replacement of the Home button will still cause the Touch ID function to failonality completely ceasing to exist. More recently, Apple started disabling TrueTone on replacement screens, even if you’re using a genuine Apple screen. Sound familiar?


An iPhone XS showing a “Service” message when another genuine Apple battery is swapped in.This pattern of behavior proves, once again, that Apple is out to stop all repairs performed by anyone except Apple themselves. The company claims that using third-party components can compromise the integrity of an iPhone’s functionality, but when genuine Apple parts have the same problem, then clearly it’s not really about third-party components at all: it’s about preventing you from having any autonomy with a device you supposedly own.


You bought it, you own it, you should be able to fix it. It’s that simple. Pairing batteries to iPhones is a gross overreach. It’s yet another instance of purchasing a product, and not being able to fully utilize it—like leasing a car, except you’re paying full price for it.Fortunately, this is where Right to Repair legislation can step in and save the day. It’s trivial for manufacturers to lock down parts and tie them together, making it easy for them to prevent anyone repairing a device other than themselves for the sake of profits. Let’s do something about it: call your representatives and go to their town halls—state legislators are in recess and visiting their districts. They would love to talk to you.


Update! Apple has issued a response to this, in a statement given to iMore:
“We take the safety of our customers very seriously and want to make sure any battery replacement is done properly. There are now over 1,800 Apple authorized service providers across the US, so our customers have even more convenient access to quality repairs. Last year, we introduced a new feature to notify customers if we were unable to verify that a new, genuine battery was installed by a certified technician following Apple repair processes. This information is there to help protect our customers from damaged, poor quality, or used batteries that can lead to safety or performance issues. This notification does not impact the customer’s ability to use the phone after an unauthorized repair.”


That last sentence has us a bit perplexed. We believe that the “ability to use the phone” involves being able to see the battery’s health information so that you’ll know when it’s time to replace the Apple phone battery again. It  ‘d   be like driving a car without an oil dipstick—how are you supposed to know if you need to add oil?

How to Get the Most Out of Your iPhone’s Battery

It’s no exaggeration to say that your entire life is essentially on your iPhone, whether you’re plotting routes to unfamiliar places or taking important calls. This means that when your battery dies, it can be very inconvenient or even catastrophic. Keeping your iPhone charged is an absolute must, so have you ever wondered how you can get more out of your iPhone battery? Read on to learn how your trusty handheld device can stay charged and ready.
How the iPhone battery works

Apple’s mobile batteries use high-density lithium-ion cells designed to store a lot of energy in a small space, resulting in an extremely thin battery that charges quickly and is great for maintaining its overall health. They also don’t receive a constant current throughout the charge; the first 80% charge fairly quickly and the last 20% much slower. This fast/slow system ensures you get power quickly when you need it, while avoiding short circuits in the battery and ultimately extending its long-term life.
In fact, the iPhone’s battery is much more powerful than you think.

It’s designed to retain 80% of its original capacity even after multiple charge cycles, allowing even devices that are years old to retain their charge, depending on how the battery is cared for Still, when your phone starts draining battery faster, you may find yourself sorely lacking that extra 20% capacity – for example, you’ll regret it if you’re in an unfamiliar city and find yourself unable to plot any routes. Use your dead phone a little


That said: There are a lot of misconceptions out there about how best to extend your iPhone’s battery life. We’ll go over some of them below, so you actually have a grasp on how to keep your devices powered and in top condition.
“The battery should be drained before charging.”While this may be sound advice for older devices and cameras, iPhones are unique in the way they calculate charge cycles. By tracking a full charge from 0% to 100% (rather than every time you plug it in), your iPhone can accurately assess the health of its lithium-ion battery. Charging your phone for a few minutes doesn’t count as a complete “cycle,” but fully discharging and charging does affect the overall  iPhone battery health measurement.


In other words, waiting until you plug your phone in when it’s close to 0% charge actually puts more stress on your battery life than charging it frequently.
3. “Don’t leave your phone plugged in when the battery is full.”Good news – you don’t need to worry about your battery wearing out from being plugged in all the time, especially since overnight charging is the best time to charge. iPhone’s power management technology is smart enough to stop the flow of electricity when your smart iPhone battery is full, so you can keep it charged all night long without worrying about shortening its lifespan.


2. “Disable Wi-Fi and Bluetooth, and close unused apps to extend battery life.”Not really: The technology behind wireless connections like Bluetooth and Wi-Fi has come a long way in the past few years, so they don’t require nearly the same energy as before. Therefore, disabling these settings will worsen your device experience without significantly extending battery life.


Additionally, closing an application does not necessarily reduce power consumption. iOS manages application processes very intelligently, and most applications immediately go to sleep when they are not in the foreground to consume minimal resources. Typically, apps consume the most power when they’re first opened, so forcing them to close and reopen will use more energy than simply leaving them alone.
Unfortunately, there are always some more battery-hungry apps for which this advice doesn’t apply. If you’re worried about battery life, it’s always a good idea to keep an eye on the worst offenders (more on managing energy usage in the next section).


1. “Only use an Apple-branded charger with your iPhone.”We could go on and on about the problems that can arise with inferior, unapproved chargers – using counterfeit electronics can cause the battery to lose capacity or even spontaneously ignite. But not all third-party devices risk damaging your device, and many offer great features at a lower price than Apple’s higher-end products. To make sure your new charger is safe, check the box to see if it’s MFi certified. All products that pass Apple’s critical quality control standards receive a seal of approval and are guaranteed to work flawlessly with your iPhone.


5 sure-fire ways to extend your iPhone’s battery life1. Turn down the brightness of your iPhone’s displaySince the process of lighting up the display uses more power than any app, adjusting your iPhone’s auto-brightness settings is a great way to reduce battery usage. Auto-brightness dims the screen based on the amount of ambient light
Your surroundings, but in full sunlight, the brightness is turned all the way up. To avoid unnecessary power consumption during the day, find some shade and lower the brightness slider in the Control Center menu.


2. Enable low-power mode in iOSLow Power Mode was added to iOS 9 to squeeze every last drop of power out of your iPhone by limiting power-hungry background processes. Normally, it’ll ask to activate when your battery drops below 20%, but you can always activate it manually if you’re having a long day. To toggle low-power mode, just go into Settings > Battery and flip the switch.


3. Update iOS to the latest versionKeeping iOS up to date is generally a sound approach, as each system update is bound to fix bugs and improve performance. When your phone runs efficiently, your battery has to do less work to keep everything running smoothly.
4. Avoid using iPhone in extreme temperaturesUsing your iPhone for extended periods of time in freezing weather or under strong direct sunlight will inevitably damage the   Apple Cell Phone battery. While it won’t damage your device, battery capacity will decrease with greater exposure to extreme heat and cold temperatures. Try to keep your phone as close to room temperature as possible optimal for battery life and performance.
5. Check your iPhone’s battery usage listNot all apps are created the same, and unfortunately, they don’t all share Apple’s philosophy on power consumption.

Sometimes, background app processes get out of hand with too many location checks or notifications about network connections. To see which apps are using the most power, check Settings > iPhone Battery. If you have an app that keeps showing up near the top, even if you don’t use it, your best option might be to limit some of its functionality… or even delete it if it’s not absolutely necessary of).
