When I first got my Droid Maxx, the battery lasted almost 2 days. Of course, I used it more so the battery would run down quicker. It's now been a little more than two years with my beloved Droid Maxx. At the end of the day, I'm down to 25%. When I look at the apps that use battery power it all comes down to screen and Android system. Anything I should look for to extend the battery life, or must I accept the old age of my Droid Maxx?
