I have two XT1053s. One purchased in December 2013 and one purchased in October of 2014. Both were NIB. This last April the oldest one was starting to show battery loss in that it would only go for about 18 hours before needing a charge. As we were going on a three week vacation I copied the contents to the new one (gotta love Motorola Migrate) and swapped the SIM. Just for grins I factory reset on the older unit and then shut it off and put it in the drawer. After we got back I copied everything back to the older one and again used it as my daily carry. Much to my surprise I found that it would easily go 24 to 36 hours on a charge.<!> So- try a factory reset before giving up on it. You may be pleasantly surprised as I was.
