Hi, my xperia L1 goes on charge every night when i go to bed, i wake up and at least half the time itll be under %50 saying not on charge. unplugging and plugging back in gets it charging again, but I don't have time to get a full charge in the morning. When I check battery stats, its gone steadilly up to like %80 at about 5AM and then plummeted to about %19 in 2 hours. where as on a full charge i normally get from about 9 AM to about 10 PM. It's a really strange problem and I have no idea where to start.
