I have had my iPad2 for 6 months now. I always charge it from a wall-socket. The last four times I have charged it, all of my music and podcasts have been erased. This morning I checked and with the battery at 98% I still had music and podcasts. About 15 minutes or so later, when I checked, the battery was at 100% but the music and podcasts were gone again. Am I doing something wrong? I haven't done anything different. This is getting annoying, because I don't have time in the morning to re-sync my ipad from my laptop. Any help is appreciated!
