The power of mobile devices could be doubled, but researchers are first focusing on improving larger smartphone batteries. How is it possible that a phone can do so many things—summon a car, order groceries, make video calls, count footsteps—and still drain its battery so quickly? The constant charging required seems outdated for such a smart device. Why hasn’t anyone made a better phone battery?

“To have a smartphone battery that lasts a week or more, you need to look for batteries with higher energy density – that’s the basic thing you’re looking for,” said Venkat Srini, a materials scientist in charge of energy storage and research Venkat Srinivasan said. Lawrence Berkeley National Laboratory’s Distributed Resources Division. Batteries are very complex objects, so it is difficult to achieve any kind of continuous improvement. “Energy density refers to the amount of energy stored within a smartphone battery. To extend the charging time of a phone or laptop battery to a week, researchers will need to double the battery’s energy density in the next few years. Recent improvements in phone batteries have allowed Energy density is increasing by about 5% to 6% per year, which means a smartphone or laptop can be used for several more hours.

Panic! Your phone is not charging, or it is much slower than normal. Try these 6 tips to get your battery working again.

Phone won’t charge: 6 solutionsIf your phone does not charge properly, this does not necessarily mean that your battery is defective or your charging cable needs to be replaced. The solution may be much simpler than you might think. Here’s what to do when your phone isn’t charging properly .

1.Restart your deviceIt’s better to be safe than sorry. It is not very likely, but your  phone battery may be faltering due to a software error.
To rule this out, it is wise to restart your phone and check whether it is now charging. Does this accomplish nothing? Then continue with the next step.
2. Clean contact pointsYour phone is a dust magnet. Especially when you constantly take your iPhone or Android in and out of your pocket or bag, the charging port is sensitive to dirt. The first solution is therefore to clean the entrance and remove any dust that may be present .Use a toothpick or small brush without hard ends. A phone’s charging port is extremely sensitive, so be careful. In any case, make sure that you do not touch the connection itself (recognizable by the pins), but only pick the dust from the entrance.

3. Cross test: use a different charger/and/or cableIs your charging port spotless again, but charging is still not possible? Then check whether the problem is with your adapter or cable. Even if the cord or charger looks fine on the outside, something may be broken on the inside.

Therefore, test whether your phone charges with a different cable or charging block. It is also wise to try out multiple sockets. If this does not produce results, it is time to connect your device to the computer or laptop.

4. Calibrate your batteryDoes your battery percentage suddenly jump from 50 percent to 42 percent and back to 45 percent? Then your battery may be charging, but you can’t see it because the battery is confused and showing incorrect values. In this case you need to calibrate the battery.

How to calibrate youriPhone  smartphone battery:
Connect your iPhone to the wall socket with the original Lightning cable;Then perform a hard reset. Do you have an iPhone 8 or newer model? Then follow these steps:Press and release the volume up button;

Then press and release the volume down button;Then press and hold the side button and only release it when the Apple logo appears.Do you have an iPhone 7 or older model? Then you perform a hard reset by pressing the on/off and home buttons simultaneously;Now charge the iPhone to 100 percent and leave the device on the charger for more than an hour to fully charge.Are you stuck? Then visit our sister site iPhoned for detailed instructions on resetting your iPhone .

How to calibrate battery for Android smartphones:
Completely drain the battery of your Huawei, Nokia, Samsung, Sony or other Android smartphone and wait until it turns off;Wait about three hours so that any residual current is out of the device;Charge your phone to 100 percent and give the device another hour and a half to fully charge. After this, your Android’s battery has been calibrated.5.Wireless charging

Your phone still not charging? Then check whether wireless charging works. This way you can be sure that the problem is with your smartphone and not with peripheral equipment. Of course, your phone must be able to charge wirelessly and you need a suitable charger.

Place the device on the charging surface and check whether the battery is fully charged. A disadvantage of wireless charging is that it takes longer, but it can save you significant repair costs. Don’t have a wireless charger at home? Then take your device to an electronics store and ask if you can use a demo model.

If you’re tired of your iPhone’s battery dying in a seemingly short amount of time,we have some tips to keep your iPhone running longer.
These tips also come directly from Apple, which means they’re specifically optimized for iPhone. We’ll even debunk some old myths (eg: Is it OK to make my   iPhone battery drain faster?).

Here’s how to make your iPhone last longer on a charge.
Update your iPhone recommends that your iPhone always have the latest software. While some of the company’s software releases do take a toll on battery life, Apple generally works hard to improve performance with each release.
dim screenYou don’t need to have the screen at full brightness. You can easily adjust it by opening Control Center (swipe down on iPhone X or swipe up on any other iPhone) and changing the brightness level. Apple also recommends using the auto-brightness feature, which dims the screen indoors and brightens it outdoors.
Use wireless networkUse Wi-Fi whenever possible
When your phone is connected to a cellular network, it is constantly trying to ping cell towers and using up as much power as possible to get a good data connection. If Wi-Fi is available, you’re better off using it since it doesn ‘t require your cell phone modem to work as hard.

Close background activityClose background applications
Background activities allow apps to extract data even when not in use. This doesn’t mean you need to close apps (Apple has debunked this theory ), but it does mean you can force your phone to stop pinging email servers. That’s it:
Go to settingsClick GeneralTap Background App Refresh and toggle it to off.Try low power modeUse low power mode

If you really want to get the most out of your battery, use Low Power Mode. Some people turn this feature on when their iPhone is dying of High quality Cell Phone battery but even turning it on to 100% can extend the life of your iPhone. “Low Power Mode reduces display brightness, optimizes device performance, and minimizes system animations,” Apple explains. That’s it:

Go to settingsClick on batterySwitch to low power modeYou’ll know it’s on when the battery icon turns yellow.Finally, don’t worry about your iPhone running out of batteryWhile there are rumors that letting a battery drain all the time can be a good or bad thing for your iPhone, these rumors are not true. Apple says it doesn’t matter when you charge your iPhone, whether you go to bed at night with 50 percent battery left or if there’s no charge left in the Apple Cell Phone battery

explains on its website that its lithium-ion batteries cycle whenever they are charged. “You have completed a charge cycle when you have used (discharged) 100% of the battery’s capacity, but not necessarily all from a single charge. For example, you might use 75% of the battery’s capacity in one day and then fully charge it overnight. If it is used 25% the next day, the total discharge is 100%, and the two days add up to one charging cycle.”

Apple also said its Apple batteries are designed to maintain “at least 80%” of their original charge capacity for what it calls “a large number of charge cycles.”

Avoid iPhone battery drain by stopping unnecessary background processes and disabling power-hungry features.The most common causes of battery drain are screen brightness and having location services enabled for too many apps.

Why is your iPhone battery draining so fast all of a sudden? 

If your iPhone loses battery faster than you’d like it to or faster than you think is normal, we can help. We’ll answer common iPhone battery drain questions, and walk you through some simple solutions to stop your iPhone battery from dying fast.

Why Is My iPhone Dying Fast after Updating? iOS 17 Battery DrainAre you wondering why your iPhone battery dies so fast? Is your iPhone losing charge after updating to iOS 17? You’re not alone. iOS update battery drain issues are extremely common and for good reason! A new iOS update drains battery because of the many big changes to your iPhone features that come with installing the most recent iOS software. The larger fall updates, like the iOS 17 update, often affect your iPhone battery more than the smaller updates we see throughout the year.
While some of this is unavoidable, there are certain things you can do to optimize your battery use and cut back on unnecessary iPhone battery drain. We’ll show you some iOS 17 battery-saving tips and offer guidance on how to preserve battery life on your iPhone.

Stop iPhone Battery from Draining Too Fast
You’ll want to start by checking your battery health in Settings. Odds are, your Apple Smartphone battery is fighting fit, but is being drained by unneeded processes running in the background. We’ll cover some easy solutions to prevent iOS battery drain on your iPhone. Also, if you enjoy learning about how to use your Apple devices, be sure to sign up for our free Tip of the Day. 
1. Check Your iPhone Battery Health SuggestionsThis is a good first step whether you’re worried that the iPhone update is draining the battery or not. Your iPhone will recommend specific changes in Settings to preserve iPhone battery life. To see why your iPhone battery is draining faster than it should be, use these steps to check Battery Health suggestions:

Open the Settings app, then scroll down and tap Battery.Tap Battery Health & Charging.
Check your iPhone battery health
On the next screen, your iPhone will suggest changes to settings that will improve battery life. You can tap on each suggestion to jump to the setting that needs changing. If you don’t want to make the change, at least you understand what’s contributing to your battery drain. 
Note: If you don’t see the Battery Life Suggestions section, your iPhone doesn’t currently see any ways to improve battery life via Settings.

However, we’ll have to disagree—there’s almost always a way to fix iPhone battery drain. Continue reading down the list to find more ways to help fix an iPhone battery dying faster than it should.
2. Dim Your iPhone Screen If Your iPhone Keeps Losing ChargeKeeping your iPhone’s screen at full brightness is a likely culprit when your iPhone battery drains fast, but it’s easily remedied. This is actually one of the main causes of battery drain and consumes more power than you might think! Here’s how to dim the screen brightness to save battery on your iPhone:

Open the Control Center by swiping down from the top-right corner of the screen. If your iPhone has a Home button, swipe up from the bottom of the screen instead.Tap and drag the Brightness slider toward the bottom, or as near to the bottom as you can go and still comfortably read your display.
reduce iphone screen brightness in control center
If you have your iPhone brightness set to a more reasonable level but your iPhone battery is draining quickly anyway, there are a lot more options for conserving battery on iPhone. Keep reading!

3. Turn on Auto-Brightness to Stop iPhone Battery Drain
Auto-Brightness settings adjust your screen lighting automatically based on ambient light levels. This keeps your iPhone from losing battery too quickly by wasting it on screen unnecessary brightness. To save battery on your iPhone by enabling Auto-Brightness:
Open the Settings app, then scroll down and tap Accessibility. Tap Display & Text Size.
Scroll to the bottom and toggle on Auto-Brightness.

Next, we’ll take a look at some lesser-known settings to help improve iPhone battery life.

4. Turn Off Raise to Wake to Save iPhone BatteryAll iPhone models have the Raise to Wake function enabled by default. This might be part of your problem, especially if you pick up your iPhone a lot or walk with it swinging in your hand. The iPhone screen constantly turning on will definitely drain your battery . To turn off Raise to Wake to save Apple mobile phone battery  life:
Open the Settings app, then scroll down and tap Display & Brightness.Scroll down to Raise to Wake and toggle it off. A gray toggle means Raise to Wake is disabled.

Once you’ve disabled this feature, you just have to tap your iPhone to wake it. Now that we’ve covered brightness settings that help prevent battery drain on iPhone, we can move on to things like apps that drain iPhone battery.

5. Turn Off the Always-On Display If you have an iPhone 14 or iPhone 15, your device has the Always-On Display that keeps your Lock Screen at a certain level of brightness, regardless of whether you’re currently looking at your iPhone. But does the Always-On Display feature drain your battery? Reducing screen brightness in any way will help to preserve your iPhone battery life, so if your iPhone battery is draining faster than you’d like, you should disable the Always-On Display: 

Open the Settings app, then scroll down and tap Display & Brightness. Tap Always-on Display.
Tap the Always-On Display toggle to turn it off (the toggle will be gray when disabled). 
Turn off the Always-On Display feature. 6. Update Apps to Keep Your iPhone Battery from Dying FastApps that need updates kill iPhone battery health. iOS update battery drain often has to do with apps. When new software is released, such as the iOS 17 update, developers have to play catch-up too. Apps that need updates may run inefficiently, or accidentally run operations in a way that’s counterproductive to the way it should be done on the most current iOS software. If you don’t automatically update apps on iPhone, taking the time to update all the available apps on your list could seriously help with iPhone battery drain! Here’s how to update apps to avoid battery drain on your iPhone:

Open the App Store and tap your account icon in the upper-right corner of the screen.Tap Update All, then tap Done in the upper-right corner.

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.

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.
We wrote an article on how to fix iPhone 14 Pro overheating issue.
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.

Surprisingly, other older models, such as the iPhone 11, have better battery life than the iPhone 12 Pro Max. We wrote an article on how to fix iPhone 14 Pro overheating issue.

Remove some cases during charging.
Charging your device inside some cases may generate excessive heat. This heat can negatively affect your iPhone’s battery capacity and shorten its life. To prevent this from happening, 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% and 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 consuming the most power. To check your phone’s battery usage, open Settings > iPhone Battery. Once you turn this setting on, you’ll see different information, such as when your phone was last charged

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.

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.

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?

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?
