IOS built-in application battery health
In iOS 1 1.3, users can manage it in the updated "Battery Health (Beta)". In addition, Apple also discloses the maximum capacity information of the battery, which can check the battery loss in real time. After updating to iOS 1 1.3 Beta2, the performance management function is initially disabled, but it will be enabled if the device is turned off unexpectedly later.
If the battery is in good condition, the system will prompt that the battery currently supports normal peak performance, otherwise don't worry. If the mobile phone triggers the peak, you can manually turn off the performance management (red circle), but the performance management function is disabled and cannot be manually enabled again. Only in the case of unexpected shutdown, this function will be automatically turned on again, and then the option to disable this function will be provided. This function only supports ordinary batteries supported by Apple.
In iOS 13. 1, the performance management function of iPhone XR, iPhone XS and iPhone XS Max can prevent devices from being shut down unexpectedly, and provide the option to disable this function in case of accidental shutdown.
When "Battery Health" cannot verify whether the batteries used by iPhone XR, iPhone XS, iPhone XS Max and newer models are brand-new Apple genuine batteries, the system will send a notice.
