I noticed, that my battery life is not so good lately. So I checked my battery stats and saw 20-30% usage from Media server. I did some research and based on some advices took out my sd card and it got better, but than it came back. This time I had to forbid some Samsung apps as push notifications etc. It was good for a while, but now it's here again and I really don't know what to do. Any advices? Stock Rom 4.3., Hard reset done, format SD done. Currently is SD out of the phone.
