Another trick to watch the test version of iOS 9.3 in the evening.

Night Shift is a new feature introduced by Apple in the first beta version of iOS 9.3, which can filter the blue light emitted by the display at night to prevent it from affecting the quality of sleep. In iOS 9.3 beta 5, Apple has modified this feature. When the device is in low battery mode, Night Shift will stop working.

In early beta versions, Night Shift only existed in the System Settings menu. However, with each release, it is constantly improving. The feature now has its own independent switch in the control center, giving users more control over how it works.

Not only can you control when Night Shift turns on and off, but you can also manually turn it on at any time you want. In beta 5, Night Shift is also turned off when the system enters low battery mode, which seems to be aimed at further saving battery life.

iOS 9.3 beta 5 was released to testers on Thursday.
