So this phone is maybe a month old now and I heard the low battery beep for the first time. Some of you may have seen my initial comments of this battery lasting DAYS w/o charging and going through some pretty heavy use. I thought I had just charged it, but plugged it in and fully charged before bed. I did the usual close aps and put it on airplane mode overnight and woke up to a battery at 51%! WTF? I charged it up and after 5 hours of light usage I was at 30%! I haven't downloaded any new aps, was at home with wifi on as usual as well. I checked aps, battery settings etc and nothing unusual running or drawing power and then removed/replaced the battery and rebooted. Looks like I'm still losing about 5% battery every 20 minutes when not being used. PLEASE HELP!
