In order to make iOS 9 more power-saving, Apple's battery management settings for iOS 9 have been separated from the "dosage" of iOS 8 and become a column of battery settings. At the same time, battery management has also added some brand-new functions, such as the power saving mode announced by Apple, which is the low power consumption mode. The official claims that the iPhone 6 battery can last at least 1 hour. In addition, through battery management, we can clearly see the power consumption of each App in the past 24 hours and 7 days.
In the open settings page, scroll down the screen, find the battery option, and open it directly.
At this time, enter the battery management settings page, and you can see the low battery mode at the top of the page, which is currently in a closed state.
After we turn on the switch on the right side of the low battery mode, the battery icon in the upper right corner of the mobile phone screen changes from black to yellow, and enters the power saving mode.
