Go to Setting>Battery>Battery Health (Beta), we can see the percent of the battery capacity. When the phone was first activated, the maximum capacity is 100%.
As we all know, with the time going, the lithium-ion battery will become less effective and the maximum capacity will reduce. In the normal conditions, a battery will retain up to 80% of its original capacity after 500 complete charge cycles.
If your phone battery capacity is between 80%-100%, the battery can support normal peak performance and the device works normally.
If your iPhone battery capacity is under 80%, you will get an information “Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity. More about service options…” In this case, you should replace a new battery for your device in the Apple Authorized Service Provider.
When you update the device system to iOS 11.3, the performance management is initially disabled. It will be re-enabled after the device experiencing an unexpected shutdown.
If you want to disable the performance management, tap the disable under the Peak Performance Capability.
