Reasonable.

IPhone is designed to provide users with an easy-to-use experience. In order to realize this experience, we must combine advanced technology with complex engineering. One of the important technical fields is battery and performance. Battery is a complex technology, and battery performance and related iPhone performance will be affected by many variables.

All rechargeable batteries are consumables with limited life, which means that the capacity and performance of these batteries will eventually decline, so they need to be replaced. As the battery ages, the performance of the iPhone may also change.

Improve battery performance in an all-round way

"Battery life" refers to the time that a device can be used before it needs to be recharged. "Battery life" is the total use time of the battery before it needs to be replaced. One factor that affects battery life and battery life lies in various ways of using equipment. No matter how you use the equipment, there are always some ways to help you.
