I have a Maxx that I purchased in June 2012. At first, the battery performance was outstanding. Now, as the phone gets older (or is it because I have more apps installed?), the battery performance is getting worse and worse. As of 6:00 a.m. today, it came off the charger and was at 100%. It is now 1:00 p.m. and the battery is at 71%. However, I've only checked emails a total of maybe 4-5 times - that's it - nothing else. No texts, no calls, no video, no games. Is that kind of battery drain normal? GSam Battery monitor says: Screen: 32.9% App usage: 55.4% Phone radio: 10.2% Those are the largest percentages. I don't have wifi turned on, ever. Anything I can do to restore the magnificent battery life of the early days with this phone?
