Iphone is dead
In the modern world, no one can live without a mobile phone, but it is difficult to stay in touch when the battery of your favorite iPhone is low. It is worth understanding that the battery of a mobile phone is a fundamental criterion for this device, and its unexpected discharge will certainly lead to a lot of problems.
In order to avoid these troubles, you should check in advance the exact battery capacity of the corresponding iPhone model. As a rule, problems with a mobile phone battery begin no earlier than several years after the start of use.
With each new year, the capacity of the iPhone battery, expressed in mAh, grows, as well as other characteristics, but the number of working hours does not increase.
To start. How does the battery work in iPhone and MacBook?
Apple equipment is equipped with lithium-ion (smartphones and tablets) and lithium-polymer (laptops) batteries. Such batteries do not require special maintenance, have no memory effect, are always ready for use, have minimal self-discharge and quickly replenish their energy reserves.
However, these types of batteries have several significant disadvantages: poor resistance to full discharge and overcharging, loss of capacity over time and depending on the number of charge-discharge cycles.
One charge or discharge cycle is considered to be the replenishment or consumption of 100% of the battery capacity. One cycle can correspond to one battery charge from 0 to 100% or several recharges, which also add up to 100%.
The cycle consists of two phases: fast and compensatory. During the first phase, the battery is able to quickly replenish up to 80% charge. The second phase replenishes the remaining 20% of the charge, but is driven by a weak current to extend battery life.
In addition, developers from Cupertino are adding all sorts of software features to optimize the charge. So, in iOS 13, a special mode has been added in which the battery will be charged up to 80%, and the remaining 20% will be replenished closer to the time of the predicted disconnection from the power supply.
The feature is located along the path Settings -> Battery -> Battery status and starts working a few days after switching on, when the system notices the usual charging phases. This way, the algorithm will protect the iPhone battery, which is connected to the charger all night, from rapid wear.
A similar feature appeared in macOS Catalina 10.15.5.
Laptops with a Type-C port will learn to track their usual charge cycles and replenish the battery only at the end of this cycle, rather than keeping the battery at 100% charge all night. But that will come later. Now let's see what the batteries in Apple gadgets are designed for.
How to check battery wear on iPhone
Despite the power of Apple device batteries, they lose capacity over time. After 500 cycles of fully charging the iPhone, it decreases by 20%. Tracking battery wear is a feature available to all iOS smartphones.
It is difficult to determine the degree of wear by the number of remaining charge cycles. If the phone is not completely discharged (up to 20%), and it is charged to 60%, this will be considered a full cycle.
Important! If the device was purchased on the secondary market, assessing its performance will be problematic.
You can quickly check your battery status using the Battery Life app. It can give the smartphone several ratings - Perfect (excellent), Good (good), Bad (bad) and Very Bad (very bad). To find out the number of charging cycles remaining, you need to go to the application menu, select Raw Data and look at the Cycles line. The application is useful because it allows you to view the battery life history. “History” shows the dates of the last checks and their data.
Important! Indicators may not be accurate if the phone has recently been repaired.
You can also check battery wear using the following applications:
- Battery Pro (for iOS);
- coconut Battery (for macOS);
- iBackupBot (for Windows).
The system itself will send a notification about battery wear when the situation becomes critical: “The battery of your device needs servicing.”
You can check the battery not only through applications, but also through Mac. To do this, you need to connect your iPhone to your PC via a cable and launch the Console app. By clicking on “BatteryHealth”, you need to select your phone in the window that opens. Afterwards, you need to check what is next to the “BatteryHealth” parameter. Ideal if it shows “Good”.
If the programs show 800 or more cycles, this is a reason to think about changing the battery - after two years of service it will become unusable. Apple is trying to reduce the load on the battery, so it has introduced a feature to slow down the iPhone. It reduces the frequency of the process, increasing work autonomy.
Removing the battery
Another way to find out the battery wear is to disassemble the phone. After removing the front panel, you need to check whether the shell has any bumps, irregularities, or a white coating. If they are present, the battery should be changed.
Using these tips, you can easily improve battery performance and extend the life of your favorite gadget.
How to calibrate your iPhone battery
How to find out the battery capacity of an Android phone
Lithium polymer batteries found in Apple products need to be calibrated from time to time. The procedure is necessary to increase the battery capacity, correctly display the remaining energy and extend the operating time without charging. It is especially important for owners of devices with worn-out batteries.
Before calibrating your phone, you need to disable several functions:
- Geolocation. You need to go to “Settings”, then to “Privacy”, select “Location Services” and disable them.
- Content update. You can disable it by going to “Settings”, then to “General”. There you need to check the box next to “Content Update”.
- Automatic downloads. In “Settings” you need to select “iTunes and App Store” and deactivate all programs in the “Automatic downloads” list.
- Display brightness. In the “Control Center” section, you should reduce the screen brightness to minimum.
This will help reduce energy consumption. Afterwards you can begin calibration. The first step is to completely discharge your smartphone. To do this, you can turn on a long video on YouTube or play a game. When the iPhone turns off, you need to wait three hours. This will allow it to be completely discharged.
The next stage is full charging. It is better to use a network adapter rather than a USB port. When the energy is 100% replenished, the phone should be charged for another couple of hours.
Then you need to discharge the device again and wait a few hours after that. The last stage is to charge the iPhone to 100%. After this, the calibration will be completed - you can enable all deactivated applications and functions.
Note! As a result of calibration, the battery capacity will be significantly increased.
How to enable peak performance on iPhone
The Peak Performance feature on your iPhone will help you avoid slowing down your device. To find it, you need to go to “Settings”, select “Battery”, then “Battery Status”. Two items will appear - “Maximum . The first in a new smartphone is 100% and drops to 80% after 500 charging cycles.
As iPhone 7 battery capacity decreases, peak performance also decreases. In such cases, older models turn off spontaneously. This is due to the fact that during stressful moments the processor requires a lot of energy. Starting with iOS 11.3, battery capacity is designed to meet peak performance needs.
The “Peak Performance” item does not contain any indicators. The user is presented with a message indicating the performance level. In new iPhones it is always high. If the battery capacity is below 80%, the performance management function will be automatically launched. In a smartphone with a normal battery, you won’t be able to turn it on manually.
Checking the degree of wear
Find out the charging time of your battery
The most successful, according to user reviews, are the Iphone 5 mobile phones in various modifications. They are characterized by four-inch screens and good battery capacity.
Not long ago, Apple released another modification of the fifth generation iPhone SE, the battery capacity of which was 1642 mAh. At the same time, these mobile devices are most often used by conservatives, since those who have tried later models rarely return to four-inch options.
So, the battery capacity of the fifth generation models is (in mAh):
- 5 – 1440;
- iPhone 5S – 1560;
- iPhone 5 C – 1520;
- iPhone SE – 1642.
If we consider that the battery capacity of the fourth generation iPhone was no more than 1420 or 1430 mAh, then we can confidently say that this figure in fifth generation mobile phones has not increased too much. However, the owner of such a model feels protected throughout the whole day, since he may not have to think about where to recharge the device.
At the same time, the iPhone SE has slightly increased its battery capacity, but has not yet been able to catch up with the sixth generation model, although it is reliable, safe and stable for a beginner and budget user.
Why and why worn-out batteries “Slow down iPhones”
The tool appeared in iOS 10.2.1 for iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE, as well as in iOS 11.2 for iPhone 7 and iPhone 7 Plus (a significant part of devices)
Apple explained that this tool works taking into account the temperature of the device, charge, level of wear and internal resistance of the battery. Thus, your device will only slow down if the presented characteristics require it. If the condition of your battery has deteriorated, and the indicators described above have not been affected, then the device will not slow down.
You can check the condition of the battery using the following four methods, which we describe in detail below in the article. We advise you to think about protecting the display of your iPhone 6 Plus by choosing a protective glass that suits your requirements.

iPhone battery life
The average lifespan of a Li-Ion battery in a modern smartphone is about 2 years. If you use your iPhone intensively enough, a noticeable loss of capacity will occur within a year. It is estimated that after 500 full charges of the phone, the battery capacity decreases by 20-25% (it is understood that a full charge is when the device is completely discharged, after which it was charged to 100%). If we consider that we usually charge the phone once a day, it turns out that within a year and a half problems will begin due to the battery losing its former capacity.
How can this manifest itself? The iPhone's performance deteriorates at low temperatures - it may start to turn off even in slight frosts. If you see that the phone turns off when the battery is 15-25% charged, this is also evidence of a significant loss of original capacity.
It is believed that the maximum number of recharge cycles is around 1000, and this is approximately 2-3 years of smartphone operation. A loss of capacity of 50% becomes critical - the battery is barely enough for several hours of operation. It should be borne in mind that using an aged battery is unsafe, so you need to worry about taking adequate measures in advance.
