Last week I was using my Note and the battery totally discharged. I plugged it in, let it charge overnight but the following day, I turned it on, started to play a game, 10 minutes later, I closed the game and noticed my battery had drained to about 65%. The battery depleted really quickly and when it got to 1%, it stayed on for ages and then finally died. I turned it back on again immediately and it showed it still had about 60% left. Again, it drained all the way to 0% so I turned it back on and it then showed 17%. I let deplete again and then the thing was properly dead. I charged it up and tried using a couple of battery calibration apps but it keeps happening. As an experiment, I left it playing a video from 100% and the thing died 2:38 hrs later. This isn't right. I've also had my micro sd card wipe and had issues with that since the drain.
Any similar experiences or possible fixes?
