Ever since I updated to 4.0.4 my bionic dies ridiculously fast now. I have to charge it 1-2 times a day and make sure I turn it off at night or it will die (I've literally had it at 100% one night and forgot to and the next morning it was already down to 75%). In the past I restricted it to 3g to save battery and was able to last 2 days comfortably. However, even after attempting to use an app (LTE onoff) and forcing the phone to use 3g, it still dies in 8 hours of varied use. I checked my battery usage and 60% of it is the OS, which is kinda crazy when it's sitting there doing nothing. Is there any way I can go back to what I previously had OS wise? (Maybe a factory reset will do it? dunno because it was such a big update) I really don't feel like I gained anything in the update but instead lost most of my battery.. Thank you for your time, sorry if something like this was previously posted but I couldn't find anything via the search function.
