Apple officially launched iOS 11.3 Developer beta 2 on February 7. After upgrading this version, iPhone 6, 6S, 7, SE and other mobile phones have added the "battery health" mode. Users who are worried that the old iPhone will reduce CPU frequency can consider upgrading.

After participating in the Developer beta program, users will receive the latest iOS 11.3 Developer beta 2. At this time, the battery health module will be added to the system settings, but this function is still in beta.

Click to enter this function, you can see the health condition of the battery. On the left is the condition of an iPhone 8 Plus. You can see that the maximum capacity reaches 99%, basically without damage. On the right is an iPhone 7 that has been used for nearly a year, with a maximum capacity of 96%. It has a certain loss, but it has not reached the level of limiting performance. If the user's mobile phone battery is excessively worn, we can also manually select whether to enable the "frequency reduction mode".
