When I first got my razr its battery usage was like 63% display 20% android OS. After I installed my stuff on it, it is now 75% android OS, 10% wifi, and 5% display. I assume that the display doesn't use any more/less battery life than it had, which means the 63% becoming 5% indicates battery use of other things rising proportionately. So it looks like my battery usage just increased several times. What happened with Android OS? I went to end most of the applications and it still doesn't change.
