Descriptions :Increase your device's battery life while idle by supporting Android's built+in Doze power+saving feature. It supports marshmallow, nougat, oreo and now pie. It offers more options for rooted devices, but it also works if you are not rooted. Doze is amazing, but it has its idiosyncrasies. The entrance can take at least 2 hours (if the device is stationary, does not charge etc.). If you move, even if the screen is off, you will not fall asleep, so many ways to conserve batteries will be lost.
