my battery dies in the middle of the day. i play angry birds a lot. i keep the screen on a low level of brightness. i only get updates on gmail, yahoo mail, and facebook. i keep gps and bluetooth off. im always in a 4G area. and the battery still dies in the middle of the day. so, i tried to delete some programs i dont use. i noticed that "stocks" was running in the background, so i tried to delete it. it only let me stop the app; i couldnt delete it, or a few others, like blockbuster. what's the deal?? i also downloaded juice defender to try to save battery, but i noticed it said in the activity log "the device is not rooted" and "error - the app package miht be damaged. please uninstall juicedefender, reboot, then reinstall it" and, if someone can help me with this unanswered question, id really appreciate it: the problem with converting my VIDEO-TS dvd files to mp4 is that i cant put on the subtitles like i can with vlc media player on the pc... any alternative?
