Is there a way to set the sleep mode timer depending on whether the tablet is being charged or not?
I normally have my Android tablet (Xoro Pad 9718, Android version 4.1.1) next to my computer on the desktop, and I like having some manual page or similar on the tablet while I'm working on the computer. In this case, the tablet is plugged into the charger, and I set the sleep mode to as long as possible, because it's just annoying if the screen turns black every few minutes. When the tablet is NOT plugged into the charger, I want a sleep mode timer of 30 seconds or one minute, to save battery life.
I'm open to a hidden setting somewhere as well as an app that detects when the charger is plugged/unplugged and changes the timer setting.
