I have owned my Bionic for just over a year. Recently I upgraded to ICS and last Friday Nov. 9th our area went to 4G. My battery is dying quickly......Example...as of 10:03AM my phone has been on for 3 hours, the screen shows that it has been on for 31 minutes, and I am down to 70% battery after a full charge. I did do a factory reset yesterday due to issues with the Android OS using up over 40% of battery - now it is at 28%. I have turned down screen brightness, lengthened updates, I have wi-fi turned off as I do not use it, etc. I don't want to have to limit everything, or it really isn't worth having the phone.
Phone completely dies each night around 10 with light use.
Any ideas without considering a new phone?
