All rechargeable batteries are consumable components that become less effective as they chemically age. As lithium-ion batteries age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged. This can be referred to as the battery's maximum capacity — the measure of battery capacity relative to when it was new. In addition, a battery's ability to deliver maximum instantaneous performance, or “peak power,” may decrease, Apple informed.
Go to Settings > Battery, then tap Battery Health and charging. Following this process, your iPhone will display information about your battery’s capacity, peak performance, and whether your battery needs to be serviced.
Notably, on an iPhone, the Battery Health screen includes information on maximum battery capacity and peak performance capability. Depending upon the length of time between when the iPhone was made and when it is activated, your battery capacity may show as slightly less than 100
