Got a 2nd Maxx because of a speaker problem with my 1st one. Battery life with the 2nd one is not a good as the 1st one was. I`ve been reading some of the posts regarding battery life and have tried some of the tricks like training the meter and doing a factory reset after the ICS update. I`ve had this 2nd phone for a couple months now and the poor battery performance was present before the ICS update. Saw a post about an app called "badass battery monitor that could tell you if an app was draining the battery. I guess the name has changed to GSam battery monitor and I downloaded it. According to it, my 2 biggest battery hogs are the screen and something called Kernel. What the heck is that and more importantly, can I do something to reduce its battery draw? Thanks!
