Why is the battery capacity of Apple mobile phone getting faster and faster after 1999?

Hello, what you want to ask is why the battery capacity of Apple's mobile phone drops faster and faster after it drops to 99? There are several reasons why the battery capacity of Apple's mobile phone drops faster and faster after 99% reduction:

1. Loose battery connection and poor contact lead to battery capacity consumption. You can check whether the battery connection is loose.

2. The mobile phone battery has reached its service life, and the aging of the battery leads to a small amount of storage, and the battery capacity suddenly drops rapidly.

3. Too low or too high temperature will affect the battery. The lithium battery used in iPhone will be unstable in high and low temperature environment, so try to avoid using mobile phone in high and low temperature environment.
