The Apple company implemented the system Night Shift in iOS 9.3 to help iPhone, iPad and iPod Touch users to protect their eyes when using the terminals in rooms without light or with low light, this being one of the new important functions of the operating system.
Unfortunately, Apple also imposed a limitation for this system, so that if we have the Low Power Mode system active, we can no longer activate Night Shift, or at least we can't do it from the menu dedicated to it in the Settings application, Configurations, or through the existing toggle in the Control Center.
For this limitation there is also a method of circumvention, so that if you have Low Power Mode active, you will be able to activate Night Shift only using the Siri personal assistant, this being most likely a bug that Apple engineers did not solve before releasing iOS 9.3.
If Apple didn't want Night Shfit to work with Low Power Mode active, then it's clear that the functions are not 100% compatible, but if you don't care about the limitations imposed by Apple, then this trick can help you bypass them without even so much effort.
