My phone has been off the charger since 12/9 @ 10 a.m. as of 12/10 7:49 a.m. it is at 64%. It is 12/11 @5:33 a.m. and I had 13% left. For me the battery is fine for my usage. Phone calls, texts and emails along with an occasional download from the Play store and fiddling around with icons and various themes. Not too shabby.
