Right, im getting awful battery life! lasting from 4-6 hours, with heavy/moderate/light usage, i've had my z10 about 7 days, always charge it from nearly flat to full, everythings always off and closed, screen brightness on minimum, on 2G/3G as can't get 4G, i have instagram and kik sideloaded too.
will it improve? because i'm failing to see 10+ hours of life like you guys are!
thanks!
