I thought my battery was performing bad (battery lasts about six hours at normal use). So I returned it and got a new one. I then deleted all of my widgets that automatically update. So far the I have had the phone off the charger for 11 hours and I only have 30% left, with below normal use. I have used all of the apps to look at battery use and what has been draining it. My question is for Android Veterans...will the battery life get better with updates? Am I doing something wrong? Battery use is almost all android system. Any insight on this would be amazing.
