On Android devices, deep sleep is a power-saving state automatically enabled after a certain period of inactivity. Basically once you lock the device or turn off the screen, the device goes into sleep mode. After a certain duration, that turns into deep sleep, which results in termination of all the low priority tasks, background apps, and unwanted processes as well as radios. The main purpose of this state is to keep your device’s various resources from being needlessly consumed, thereby extending battery power. By default, the OS governs the default delay after which the deep sleep state is activated. However, there are certain tools out there that let you take control of this particular feature, but not many surpass Root Uninstaller’s Deep Sleep Battery Saver – an option-packed Android app featuring multiple profiles to control your device’s deep sleep duration, scheduling and behavior exactly as you wish.
