In iOS 11.3, it became possible to check the status of the battery and enable maximum performance with a worn battery. In this manual, we will talk about all the nuances of this function.
After upgrading your iPhone to iOS 11.3, the “Battery Status” item will appear in the battery settings. Apple warns that the battery is a consumable item, so you need to monitor its condition.
You can view the battery status on iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus. IPhone 8 and iPhone X have this section, but performance management works differently than previous generations of the iPhone.
To see the battery capacity you need to open "Settings" → "Battery" → "Battery Status". Indicator maximum capacity reflects the current state of the battery. On new smartphones, it should be 100%. A lower value means the phone will need to be charged more often.
The second section is called "Peak performance". To find out if this setting is activated and turn it off if necessary, you need to read the fine print.
Peak performance limiting is automatically enabled if the iPhone starts to restart unexpectedly. After enabling this function, a corresponding notification will appear on the lock screen.
If the battery is in good condition, it will be written in the settings that the iPhone supports peak performance. You cannot disable or enable it manually.
If the smartphone suddenly shuts down because it cannot support peak performance, it will turn it off. Peak performance regulation slows the processor to reduce maximum battery power requirements.
This setting can be turned off. To do this, click the blue “Disable” link. It is not possible to re-enable peak power limitation manually. The smartphone itself activates this function after the next unexpected restart.
You can disable peak performance limits even when the battery is in critical condition. In this case, the probability of an unexpected shutdown will increase sharply, and an additional item will appear in the settings that explains how to replace the battery.
Sometimes the system cannot determine the condition of the battery. In this case, the user will be prompted to replace the battery at one of Apple’s authorized service centers.
The “Battery Status” feature appeared after it became known that Apple automatically limits the performance of older iPhones in order to maintain autonomy. After that, the company had to make an official apology, and in response, dissatisfied users began to sue Apple en masse, demanding material compensation.
