I use it to play music while my child sleeps, the screen stays off when playing and runs off ac adapter (2.5mm/barrel type) what I'm wondering is if I can just turn off the music player and leave tablet on during the day, or is it better to turn it off and back on at night; I wonder if it's actually running much in sleep mode and if it would actually be easier on the system to stay on than to shut down and start back up every night? It has Lollipop version; here is link to it:
