I would get close to 40 hours of battery life with moderate use. I upgraded to ICS a month ago or so then did the factory reset, and this has been the amount of time I could get on a single charge. Then last week I noticed a dramatic decrease in battery life. Since then I have been able to get only about 6 hours if I just leave the phone in standby and hardly use it at all. I have not recently installed any apps, did a reset and closed all open apps. I have also been in a full coverage area. I have noticed that the up and down arrows next to "4G LTE remain lit. THe phone also gets hot to the touch just from it sitting on my desk. I believe that something is either running or syncing continuously and draining the battery. I brought the phone to the VZ store and they could not find the issue. They are overnighting me another Maxx, however I really do not want to go through the hassle of switching everything over. Any suggestions on what this could be or how to fix it? Thank you in advance!
