I got the Droid Maxx HD for its awesome battery life. And at first, it was terrific -- went two days or more between charges (I am a moderate user -- phone, mail, map, calendar, light banking, not much video or audio). A year later, it isn't so awesome. I was out today for 3-4 hours and it declined from 55% to about 15%. IOW, it now won't last out the day. I quit iPhone in part because of the crummy battery life, and now it is coming back on my Maxx HD a year after purchase. At this rate, it won't last another year until my next subsidized phone! I initially conditioned the battery as directed -- let it run down to zero 3-4 times -- correct? I haven't done that since -- do I need to? Any other care-and-feeding needed to keep battery life somewhere decent? I don't do any demanding apps to speak of, and now am in the habit of closing apps when not in use. but not much help. Thanks. --David.
