iOS 9.3 came bundled with a long list of improvements to the user experience, as well as a new major feature for the display, named Night Shift mode. This new feature lowers the amount of cold light on the screen while increasing the warm one, to ensure the eyes are well protected when using the phone in the dark. Unfortunately, Apple believes that Night Shift shouldn’t operate when the device is in Low Power mode. Fortunately, there is a way to activate both functions simultaneously.
When you start Low Power mode, Night Shift can no longer be activated from the quick actions menu, nor from the screen settings. Basically, it is switched off completely until the Low Power mode is deactivated. This decision is, at least strange as Night Shift mode is recommended for use indoors when the phone battery is usually running low. But Siri is the solution to this problem, the digital assistant having access to functions that normal users don’t.
All you have to do is to activate the Low Power Mode from the battery tab and initiate a conversation with Siri. The command to start the Night Shift mode is “turn on night shift” and the feature is immediately activated. There you go, you can now sit comfortably in you bed during the evenings without worrying about excessive battery consumption and a yellowish screen that doesn’t bother your eyes.
If you fail to follow these instructions, the video from above, made by 9to5Mac, demonstrates the whole process.
