Maybe because I have a bit less screen time than some during the day but I have no complaints. Charged it initially and after 27 hours of standby and 3 hours 10 minutes of screen time I was at 29%. While the screen time is not remarkable I downloaded almost a gig of apps setting it up, sync's all my old emails and messages, etc and I have everything turned on. Took it off the charger last night and still had 49% almost 24 hours later. Charged it tonight and took it off the charger. 1 hour and 55 minutes off charger sitting idle other than periodic email checking and I am down to 97%. I can handle 1.5%/hr with wifi, bt data, etc all on. Plus - I haven't uninstalled or disabled ANYTHING. I have left it completely alone in that regard so far.
