Hey guys. I recently got an atrix 4g. I was excited to hear it has a 1930 mah battery. However, im only getting 3-4 hours of web browsing out of it before it dies. Yes I have calibrated the battery. I did everything that all the guides said. I turned off data. Brightness on auto. No gps. I kill backgrounding apps every 15 minutes. I would love to underclock, but there is no such thing for a tegra 2 yet. I might just go back to my iphon e. Any suggestions anyone?
