Is it possible to change the battery on an iPhone? iPhone battery replacement prices

As for anyone mobile device, autonomy is very important for iPhone and iPad. Every year, user demands are growing, use cases are expanding, and battery capabilities are expanding mobile gadgets remain at the same level due to constantly decreasing thickness and weight.

Complaints about insufficient time battery life can be heard from many users, but how can you understand whether the battery of your device needs to be replaced or whether you are simply using it too actively? This will be discussed further.

Discharged or not

This will sound trivial, but first you need to understand whether the device itself is discharging or you are discharging it. To do this, simply refrain from active use for a while and monitor the charge level. It is best to fully charge the device and leave it overnight, after taking a screenshot of the charge level at current time. Don't forget to turn off notifications as well to eliminate the possibility of being drained by too many pushes.

Check the charge level in the morning. If it has not changed or dropped by a couple of percent, then everything is fine with the battery and the accelerated discharge is caused by active use. If the charge has dropped by more than 10%, something is still discharging it. In this case, move on to the next point.

Determining the cause of the discharge

We need to determine where the charge goes: is it being “eaten off” background processes and service or discharge is caused by a decrease in battery capacity due to wear. This is quite easy to do through the built-in battery usage statistics function. Starting with iOS 7.0, we have not only meager usage and expectation figures (although there are plenty of them), but even detailed statistics on applications.

The point is that in the mode iPhone waiting and the iPad should not be discharged, which means the waiting time from the statistics menu should be significantly longer than the time of use (even though the device is at rest).

If your waiting time is equal to or almost equal to the usage time, then there is background activity of applications or services, which is the cause of the discharge. It's worth checking out the apps on the list and their access to content updates, geolocation, and more. Here are some more useful tips for you.

If everything is in order, and the battery still lasts very little even with gentle use, move on to the next point.

Testing the battery

The problem is almost certainly battery wear, which is inevitable during long-term use. During the charging and discharging process, the battery capacity decreases. In the iPhone it drops to 80% after 500 recharge cycles, the iPad can withstand twice as much - 1000. Find out how much the maximum battery capacity on your device has decreased. If the drop is too large and the current battery life is not satisfactory, it’s time to change the battery.

If your device has been updated to iOS 11.3, then you can find out how much its battery capacity has decreased over the entire period of operation, without additional programs. To do this, open the “Settings” → “Battery” → “Battery Status” section. The device will show the current value of the maximum capacity as a percentage of the original.

If your device has more than old version iOS, you can check your battery status using free application Battery Life Doctor. Launch it and click Details next to Battery Raw Data - in the next menu you will see the Design Capacity option (initial maximum capacity). The current maximum battery capacity as a percentage of the original will be displayed next to it.

Another way to find out the battery status is in the iBackupbot program for macOS and Windows.

Download the program from the link, open it, connect the device to the computer and click More Information. We are interested in the DesignCapacity (initial maximum capacity) and FullChargeCapacity (current maximum capacity) indicators. All you have to do is calculate the difference yourself. If it is too large, consider replacing the battery.

What to do next

75–80% of the factory capacity is not yet fatal and you can easily live with this, but if such autonomy is not suitable for your use case, you will have to replace the battery.

It is better to do this in official or trustworthy services. If you decide to replace it yourself, then do not buy suspiciously cheap batteries and keep in mind that, unlike the iPhone 4/4s, in later devices (and all iPads) the replacement procedure involves complete disassembly devices, which requires appropriate skills.

And further. Before you go to service center, try calibrating the battery. It helps many, and trying is not torture.

The convenience and quality of an iPhone largely depends on its capacity. battery, its ability to hold a charge as much as possible. Every iPhone owner periodically wonders: when do you need to change the battery?? Along with this, the owner may encounter the problem of poor-quality charging, which raises another question - What to do if the iPhone does not charge well? These two issues are not always related to each other. Let's figure it out sequentially.

The answer to the first question is quite simple - you need to change the battery as its capacity decreases. After almost every iPhone charging and discharging cycle, the battery capacity gradually decreases. Statistics show average normal operation iPhone batteries– about 500 cycles. This is the indicator after which it is recommended to replace the battery, since the capacity reaches 80%. Naturally, each case is individual; theoretically, the battery can operate for more than 1000 cycles, or it can “run out” after 50 charges (for example, due to power surges or oxidation). Therefore, if your iPhone turns off at 20% charge or constantly heats up, you should pay attention to the battery. In any case, finding out the number of charging cycles completed and the battery capacity will help specialized programs or service center employees. They will also issue a verdict on the need to install a new battery.

If your iPhone is not charging well, you must first find the cause of the problem. The easiest way to do this is by service center professionals, because the further performance of the device depends on how accurately the problem is identified. But you can try to find and fix some defects yourself.

The main causes of rapid battery death

• Software problems. The controller responsible for the charging process is controlled software. If the software is frozen or does not work correctly, then when connected to the charger the controller does not receive the necessary command, and the iPhone won't charge. Exit - reboot the smartphone by simultaneously pressing two Power + Home buttons;
• The charging socket is dirty. A fair amount of debris regularly accumulates in the charger. Various particles of dust, lint, and wool contaminate the charging port, preventing the charger from functioning normally. You can try to clean out all the junk yourself with a toothpick. The main thing is not to aggravate the situation by damaging the connector;
• PC USB port malfunction – possible reason lack of charge. Try using others;
• Faulty charging cable. Try using a different cable, naturally the original one. The use of non-original cables can lead to a lot of problems;
• iPhone temperature. You've probably noticed more than once that iPhone turns off when cold outside or in the heat.

Simple malfunctions are over. Now comes the turn of more complex ones, which you are unlikely to be able to fix on your own.

• Failure of iPhone internal parts. Most likely either the battery or the charging controller has failed. If the battery does not charge at all, or loses its charge very quickly, gets very hot, or rejects the cable, most likely the problem is with a specific controller. Oxidation of the charging connector and other reasons are also possible. In any case, only a certified service specialist can finally figure out the problem and fix it.

Some useful tips to help extend the life of your iPhone battery

• Use only original chargers, only they can effectively protect against voltage surges;
• Do not increase the battery capacity of your iPhone, carrying out several complete charge-discharge cycles to zero, as was previously recommended. Battery modern iPhone does not need such training;
• Don't constantly charge your smartphone– Frequent charging harms the battery. Charge your iPhone as needed, trying to avoid extreme values;
• Don't be afraid to leave your phone on long-term charging(for example, all night)– when using a high-quality adapter, the power supply is stopped by a special controller after reaching the maximum charge;
• You should not actively use your iPhone in the cold, stressful situations do not contribute to the performance of the battery;
• Batteries increased capacity does not exist, they are all standard. So you shouldn’t trust those who try to convince you otherwise.

The best way to extend iPhone performance– compliance with all operating rules. In case of problems, please contact our service center specialists for

One of the inevitable features of modern technologies is the constant need for power supply from the network. Smartphones and tablets cling to sockets like vampire ghouls to the tender necks of young ladies. The battery of the iPhone or iPad was no exception, which, although they are somewhere close to the limit of technical perfection, when drained, they make the devices more like useless bars of metal and glass.

In this voluminous article, we will look at a lot of useful and simple tips on how to increase battery life on the small old iPhone 4, and on the small modern iPhone SE, and on the huge iPad Pro. The article is focused on iOS 10, but most of the tips are also relevant for iOS 7, iOS 8 and iOS 9.

So, let's move forward from system settings that require calibration, to third-party apps that help your iPhone or iPad battery last longer. There are 36 exciting and useful steps ahead.

If you are a happy owner of an iPhone 6, make sure that everything is in order with your battery, because back in November 2016 Apple of the Year announced free program replacement of batteries for iPhone 6. A sign of such a warranty case is an unexpected turning off iPhone 6. If it bothers you, feel free to contact customer service.

1. Don't bother shutting down apps

Let's start by debunking a common myth about saving iPhone or iPad battery. iOS users tend to terminate apps when exiting them, which seems like a logical way to save battery power. But, in fact, this is not such a good idea. As the folks at the Apple Store explain, when you close an app, it's removed from RAM, so the next time you open it, it's loaded there again. These upload/download manipulations cause more damage to the iPhone than if you simply left everything as is.

Apple itself, represented by Craig Federighi, confirmed that closing the application does not affect the battery in any way. At one time, Tim Cook was asked by email the question: “How often do you terminate your applications, to what extent is this necessary for battery life?” Federighi answered for him: “No and no.”

So our concerns about draining energy from the battery unused applications are groundless, because they are updated only in background, if set to Background Update. If Background Refresh is not enabled, programs will not be able to run in the background unless they are playing music, recording audio, using location services, or checking VoIP calls such as Skype.

1. Enable Low Power Mode

iOS 10 (and iOS 9) includes Low Power Mode, a power-saving mode that reduces overall power requirements and extends battery life. Apple claims this mode will give you three extra hours of iPhone battery life.

Power saving mode in iOS is not enabled by default. It is offered to you when the device's charge reaches 20% battery level. You turn it on and immediately the battery indicator turns orange from red or even turns green if there is enough energy. The mode automatically turns off when the battery charge reaches 80%.

But you don't have to wait until your iPhone battery reaches 20% charge. You need to turn on the power saving mode forcibly, for which you just need to select “Settings” - “Battery” and move the button there.

The tests carried out confirmed that Low Power Mode significantly saves battery. According to users, by midnight on normal mode The iPhone discharges up to 17%, and with energy saving the same figure is 49%. These savings come from stopping email, Siri, background app updates, automatic downloads, and some visual effects. Surprisingly, even with all these features disabled anyway, Low Power Mode still makes an impact.

This tip only works on iPhone, not iPad. The iPad does not have a low power mode.

1. Updating iOS

When problems start with your iPad or iPhone, including those related to battery life, one of the most useful and universal solutions is updating iOS. Apple uses its regular and free updates operating system to eliminate vulnerabilities, bugs and crashes, and it is possible that the problem you are experiencing can be fixed simple update. On the battery front, for example, iOS 10.2.1 solves the well-known battery charging bugs for the iPhone 6, iPhone 6 and Plus variants.

1. Or maybe the battery life has expired?

Unfortunately, iPhone batteries do not last forever. Sooner or later there comes a time when the device must be examined by a specialist in order to make a final verdict. Fortunately, iOS 10.2.1 introduces such useful system, as a warning about battery repair and replacement. The message reads: “Your battery needs service.” So, if you have updated, you can wait until you see this message.

1. Checking Battery Usage

Exists good way to make sure the iPhone or iPad battery is working properly, or the device itself is in good condition regarding power supply. This will require a small test.

You need to go to “Settings” - “General” - “Battery” to look at the battery load report. Here you can compare the energy consumption during use and in standby mode. Usage time is how long you have used the device since the last charge, standby time is the total time that has passed since the last charge. The usage should be much less than standby mode (unless you use your iPhone non-stop until you turn it off).

To test the battery, record the usage and standby time, and then put the device into sleep mode by pressing the on/off button at the top. After five minutes, look at the indicators again. If your device is working properly, your usage time should have increased by less than a minute, and your standby time should have increased by five minutes. If you see an increase in usage time of more than a minute, something is preventing the phone from sleeping and there is a battery drain problem. This check works well starting from iOS 9.

Most likely your iPhone battery is dying due to some application or settings. Email, and not damage to the device itself and the battery.

To stop unnecessary leaks, see following tips In this article.

1. What apps drain your battery?

In iOS 10, 9, and 8, you can see which apps are the biggest battery drainers. Go to “Settings” - “General” - “Battery” and then at the bottom there is a visual graph of which of your applications were the most power-hungry over the last 24 hours or 7 days. Facebook and VKontakte will most likely be at the top, then Safari. Obviously, these are frequently used applications. It is worth paying attention to any applications that drain the battery with background activities, which will be marked in the table. It is necessary to decide what kind of activity this is. Let's discuss this below.

1. Facebook

Facebook has been accused of draining batteries on iPhones and iPads in iOS 9 and even 10. Facebook itself admits that its iOS app uses a lot of resources in the background. Thus, in February of this year, The Guardian wrote that the removal Facebook apps can save up to 15% of iPhone operating time. At the same time, you should not give up Facebook itself, which can be quite conveniently used on the Facebook website via Safari.

Take a look at your battery usage log (Settings - Battery) and see how Facebook is eating up your battery. Its share in the discharge can be up to a quarter of the total volume! Facebook admitted its fault and then tried to fix it, but the battery drain problems persisted.

1. Turn down the brightness

The Retina display you most likely carry around on your favorite device contains huge quantity more pixels than iMac. Even the number of pixels on an iPhone screen can be compared to MacBook Air. It's no surprise that the screen has become one of the main sources of power consumption in your iOS device. Pixel lighting Retina display requires a lot of energy. Testing revealed that excessive screen brightness was the main cause of iPhone battery drain.

With the iPhone 5 screen at full brightness, the shock lasted 6 hours and 21 minutes while playing 720p video. If I turned down the screen brightness by half, the phone had been sitting for 9 hours and 48 minutes. The difference is huge.

So we save battery power by adjusting iPhone brightness. Fast access This setting is accessed via a slider in Control Center, which is accessed by scrolling up from the bottom of the screen. Drag the brightness slider to the left until the dimness begins to cause despondency and discomfort. You also need to open “Settings” - “Display and Brightness”, where you make sure that the “Auto-Brightness” function is disabled so that your phone does not turn up the brightness every time it wants. True, Apple assures that automatic brightness is precisely capable of saving battery life, therefore, if manual settings are still too dim for you in bright light, then you will probably have to leave everything as it is.

In iOS 7, you can find the adjustment in “Wallpaper and Brightness.”

1. Automatic blocking

While the screen is on, it consumes power relentlessly, so you need to make sure your iPhone or iPad doesn't wake up whenever it wants. When setting for maximum battery life, you must set the auto-lock to the shortest 30 seconds. This feature was added only in iOS 9, it is also available in iOS 10. Go to “Settings” - “General” - “Auto-Lock” for iOS 9. And “Settings” - “Display and Brightness” - “ Automatic blocking» to put the device to sleep after 30 seconds of inactivity in iOS 10. This will significantly extend battery life, but it can be annoying. In this case, if you are annoyed by being forced to fall asleep, you just have to shut it up for half a minute, you will have to get used to pressing the “Sleep/Wake” button at the top iPhone more often on one's own.

1. Airplane mode

The antenna is the biggest consumer of energy as it constantly checks for nearby Wi-Fi and cellular networks. Even if you're not doing anything, the phone is simply draining the battery in your pocket as it continuously monitors itself relative to base stations to switch. If you don't need to call, you don't wait for a call, don't use this moment Internet, no need for GPS for maps, you can put your phone in airplane mode and save a lot of energy for use iPhone antennas. Despite the abundance of “ifs,” such situations still occur quite often, and besides, savings for different types networks can be configured separately.

To activate "Airplane Mode", simply enter the control screen and tap the airplane icon on the left top corner. In addition, “Airplane mode” is enabled in the settings.

If you need to use Wi-Fi, even in airplane mode, you can turn it on separately, just click on wifi icon.

“Airplane Mode” especially helps in low coverage areas, since the iPhone maintains antenna power at maximum in such places. So, in the area with bad signal, in the basement, your iPhone will desperately try to boost the signal at the expense of the battery.

As Scott Lovelace told Apple Store Genius, your battery will drain quickly even with strong Wi-Fi because the phone still requires cellular service for calls and texts. Which, in principle, is a no brainer without such authorities. So don't be surprised if iPhone office sits down faster than, for example, at home, it’s not such hard work, it’s just a crappy connection.

1. Turn off Wi-Fi

If you need a full-fledged phone, but you can do without Wi-Fi, turn it off (Control Center and click the Wi-Fi icon). So the phone will stop searching available networks Wi-Fi and save battery

It should also be remembered that bad wifi will require more energy to transmit and receive data. But it's still better to use Wi-Fi, if possible, than 3G. This isn't about finances or security, it's about the fact that the iPhone consumes less power when accessing data over Wi-Fi than when performing the same task on 3G networks. Therefore, Apple gives different battery discharge times for 3G and Wi-Fi. And if the Internet use on the iPhone 6 Plus is the same for both options - up to 12 hours, then in the iPhone 6 these figures are different: 10 hours on 3G and up to 11 hours on Wi-Fi. iPhone 5s and iPhone 5c – 8 hours on 3G networks, up to 10 hours in LTE mode and 10 hours in Wi-Fi. IPhone 4s - 6 hours on 3G networks and 9 hours on Wi-Fi networks.

1. Turn off Bluetooth

Most likely, Bluetooth on your iPhone is not needed most of the time, so it is better to turn it off. Swipe across the screen and in the Control Center, tap on the icon that looks like a runic B. So, after iOS updates Bluetooth remains turned on, so you don't even have to know it's active. Bluetooth drains your battery noticeably, so if you're not using it to connect to speakers, headphones, or other accessories, feel free to turn it off.

1. Disable AirDrop

Starting with iOS 7, the AirDrop service is built into the iPhone, which requires Bluetooth turned on. This feature allows you to transfer photos and other files to nearby iPhones. Unfortunately, this service drains your battery because it searches for nearby smartphones. AirDrop is disabled in Control Center; enable this feature only when necessary.

1. Disable 3G and 4

If you can live without the Internet at the moment, but need to be connected, turn off 3G or 4G. Go to the “Settings” section - “ Cellular network” (or “Mobile Data”) and set the “Data” switch to the “Off” position. If your iPhone supports 4G, turn off this network, especially if you are not using it, which will also save battery.

Typically, the iPhone receives two signals at once: one for calls and SMS, and the other for data transmission, turn off unused channels.

It should be noted that, according to Scotty Loveless, the signal strength indicator on the iPhone only shows the signal strength for the connection, not for data. So, your iPhone may show 2-3 dots, but in fact have a lousy 3G connection, as a result of which the smartphone will go into enhanced search mode and drain the battery.

1. Turn down the volume

Surprisingly, even adjusting the volume affects battery life. If you are listening to music or other audio from your phone, turn down the level using the volume buttons. At the same time, you can save battery power by switching to headphones, which is more economical than using internal ones. iPhone speakers. And the best part: the music equalizer also wastes your battery!

1. Turn off vibration

Well, since we have dealt with the screen and sound so much, it remains to save on vibration. Turn it off, because a simple sound, without bouncing, will consume less energy from the battery.

1. Down with visuals

Starting with iOS 7, we are pleased with various volumetric effects, nice Parallax features, thanks to which icons and notifications float attractively on the wallpaper. Nice, but they use it all the time GPU iPhone, wasting precious energy. An extra half hour of using a smartphone is easily spent on these bells and whistles.

Switch to static rather than dynamic wallpapers that move when you tilt the phone. This will save a little battery. When setting new wallpapers, turn off perspective and zoom. You can do this in “Settings” - “General” - “Accessibility” and turn on “Reduce Motion” to turn off parallax effects.

1. Games and heavy applications

Obviously, your iPhone's battery drains faster the more apps it is loaded with. Some burn through the battery much faster than others, such as those that use the CPU and GPU intensively. So 3D games or GPS for maps use much more energy than reading a book.

If you play games with luxurious graphics and visual effects, your iPhone battery will drain before your eyes. So if you are away from charger and besides, you are waiting for an important call, it will not be the best to play such games best idea. In fact, even fairly simple games often use a fairly complex 3D engine, and so when the battery is in the redline, avoid them completely.

1. Camera

Probably everyone has experienced when the battery on your iPhone runs out just when you are taking a breathtaking night photo with friends? Therefore, if you are running low on battery, you need to minimize your use of the Camera app and even more so avoid flash.

1. Turn off Spotlight search

Just like on the Mac, iOS has Spotlight Search running constantly in the background, indexing your data so it's easy to find later. This is, of course, great, but when you have little energy, it is better to refrain from indexing. Go to “Settings” - “General” - “Spotlight Search” and turn off some or all Spotlight categories.

1. Notification Center

Unfortunately, notifications do not have a global switch and if you run out of power, you have to change notification settings for all applications. Every time a notification arrives, iPhone screen lights up and makes a sound, which inevitably consumes the battery. Each message wakes up your device for 5-10 seconds. It’s quite possible to live without notifications in non-critical applications, so go to “Settings” - “Notifications” and scroll down the page. Halfway down, in the INCLUDE section, there is a list of built-in iPhone applications and third-party applications installed on the phone. Click on each one that you are not interested in and select the “No” option to prevent banners and alerts from being sent. You can also uninstall apps directly from Action Center.

1. Stop email synchronization

You can configure your iPhone so that it will immediately download letters from the server and immediately notify its owner about this, so that he will not miss a single new email. But when your iPhone is away from a power outlet, you can save money on receiving emails by checking your email only when necessary.

The Push Notification service constantly polls the server, so when you receive a new email, your iPhone knows instantly. You can disable the service in “Settings” - “Mail, Contacts, Calendars” - “Get new data” - “Turn off”. Instead, you can choose to receive email at regular intervals. Using Push for electronic requires much more sharing data and battery consumption than selectively receiving mail. You can select "Every 15 minutes", "Every 30 minutes", "Hourly" or "Manual" to receive emails only when you request them.

1. Removing redundant email accounts

Multiple email accounts consume both your precious time and battery life. All yours Accounts can be redirected to one postal service, and then delete additional ones in “Settings” - “Mail, Contacts, Calendars”.

1. Disable iCloud

Likewise, if we want to squeeze out the next batch of battery juice for ourselves, turn off everything that doesn't really need to sync via iCloud. It uses connectivity and energy, so you can save battery power by turning off unused features. Go to “Settings” - “iCloud” and turn off everything you can and even a little bit of what you can’t.

1. Disable automatic time zone

The iPhone can automatically update its time based on where you are. Since the iPhone determines the exact time through location services, this uses some battery power. So, unless you're flying back and forth on hourly trains, go to Settings - General - Date & Time and set Automatic to Off.

1. Location services

Most often, it is not iOS itself that causes the iPhone or iPad battery to drain, but the applications that run on it. There are a number of apps that use location services on your iPhone that can play a role in draining your battery. It even makes you a little angry, especially when it’s unclear why the hell some of them need to know where you are now. To prevent apps from using location services, go to Settings - Privacy - Location Services and turn them off completely, or deselect any apps you don't need to access GPS.

1. Disable Hey Siri

Siri does reduce battery life a bit, but if it's a "Hey Siri" service it drains even faster and should be disabled if you want better battery life. Go to Settings - Siri and make sure "Hey Siri" is not turned on.

This feature, when activated, causes it to listen for the phrase “Hey Siri,” and when it hears it, Siri Assistant turns on and prepares to to the following teams. This sounds tempting, but constant readiness to hear the magic phrase takes a toll on your battery life. It is for this reason that previously “Hey Siri” only worked if the gadget was connected to a charger, but due to its popularity, Apple relaxed this condition when updating iOS.

1. Disable background content refresh

Before iOS 7, if you switched between apps by pressing the Home button twice, the old app would freeze and have limited access To system resources. With iOS 7 background applications You're allowed to update your data periodically, something iOS 8, iOS 9, and iOS 10 inherited. So when you open the app again, you'll immediately see the most recent results.

This can be useful in certain circumstances, but most of the time it wastes battery power at the expense of the apps you actually need. When extracting maximum energy from your battery, turn off background update content. Open “Settings” - “General” - “Content Update”. Here you can completely disable this service or reduce the list of applications active in it.

1. Disable app updates

Another feature added to iOS 7 was the ability to update apps without user interaction. The feature remains in iOS 10, 9 and 8. This feature allows apps to always be up to date, but can drain the iPhone's battery. In addition, some users prefer to update data on a case-by-case basis, because sometimes the developer completes his programs in such a way that it only gets worse. Fortunately, you can stop automatic update applications. It can be turned off in Settings - iTunes & App Store", scroll to " Automatic download" and disable "Updates".

1. Display battery charge as a percentage

It's a good habit to keep track of your battery level as a percentage rather than as a bar icon. You can switch in “Settings” - “Battery” - “Battery percentage”. Now you will have more detailed information about how much time your device has left to work. True, for reasons known only to Apple, iPod touch does not have such an opportunity.

1. Battery calibration

If, despite all the advice, your battery life is running out sooner than it should, for example your iPhone drains from 17% to 2% in a matter of minutes, the device may need to have its battery calibrated. Apple recommends periodically completely draining your iPhone or iPad's battery and then charging it completely, from 0 to 100 percent. This must be done at least once a month. The process is called calibration and helps the device more accurately estimate battery life. Battery calibration ensures that you know when to charge your battery. The procedure itself does not extend battery life.

1. How much time do you have left?

There is no simple answer to this question. iOS 8 introduced the ability to see which applications have become the biggest consumers of battery, plus we know the percentage of remaining battery charge and can estimate how long it will last. But there is no accuracy, which is due to the dependence of the battery charge on your unpredictable activity.

However, there are third party applications, which can give some more detailed information about how much operating time is left. One such app is BatteryDoctor (formerly BatterySaver) from KS Mobile. This tool offers a wide range of system settings, with an emphasis on saving battery power. The app's main screen shows an estimate of your remaining battery life based on what's happening in the background and your current system settings.

In principle, BatteryDoctor suggests doing the same thing as we discussed above, only it immediately displays the expected effect of the manipulation.

1. Should you leave your iPhone on charge all the time?

When you come to the office, put your iOS devices to charge so they are fully charged for the journey home? But could this practice of constantly charging your iPhone harm the battery? There are some discussions about this. In general, the iPhone stops charging the battery once the battery is fully charged, so the battery cannot be "overcharged" per se. However, from experience with laptops that remain plugged in all the time, their batteries lose their ability to maintain a charge. The only thing that can be definitely recommended here is to make sure that the battery is discharged to zero at least once a month.

1. Turn off your iPhone

The last resort that is guaranteed to save energy if you need your iPhone for an entire weekend or the power goes out is to turn off the device when not in use. First, it will discourage the temptation to play something to pass the time. And secondly, it guarantees that even background tasks will not waste power.

However, be aware that if there is only a few percent of battery left, your iPhone may not turn on again if you turn it off. In such circumstances, switch to airplane mode.

1. additional battery

If you need even more battery life after following the advice, you should consider an option with an external battery pack or a case with a built-in battery. There are many noteworthy devices on the market that will prolong iPhone work on significant lines.

Results

You should not mindlessly carry out all 36 listed points. It is enough that you have become acquainted with them and now understand the main principles of saving energy on your iPhone. Use this information in order to wisely save battery energy, subtly and optimally adjusting the device to your needs. Every time the battery treacherously runs low inopportune moment, you'll know roughly where you could have saved some energy, and the next time a depleted iPhone battery will be harder to catch you by surprise.

The battery on an iPhone may sooner or later become unusable for various reasons. Usually Apple company uses lithium batteries, which serve in accordance with their purpose for no more than two years. Of course, everything depends on the operating mode, storage and use conditions, and proper charging. If the battery is lying idle, that is, the iPhone is not actively used, and is not charged from time to time, then the battery may completely lose its usefulness in one year. When it's time to replace your iPhone's battery, be patient and take it to a certified service center.

If the battery on your iPhone has become unusable and you need to replace the iPhone battery, do not resort to random craftsmen or pseudo-workshops. You may find yourself in an unpleasant situation when they install a used battery device on your iPhone, and not a new one, and the battery model may not be original. It’s worse if they offer you to install a battery with a more powerful capacity, believe me, such innovation can ruin your device.

To change the battery device in an iPhone, you need to pay from 1,500 to 5,000 rubles, depending on the smartphone model. Therefore, you can save a lot of money by replacing the battery on your iPhone without resorting to service centers.
