I am a poweruser on my S3. I am streaming music, reading forums, flashing roms, texting, and tweaking a ton (my display is on a lot). I have to charge after 8-10 hours. If I am otherwise engaged, I can easily be at 50% after 12-16 hours. But, if I am travelling and switching between 4g, 3g, and 1x (gag), I'm in trouble. Not bad for a 5" screen.

battery using for 3g data usage and gaming..

If I use my evo 3d stock normally it take from 100% to 0 in about 12 hours. I think it should last longer

Basically 10% per hour of usage. 3%/hr in standby.

Got this on my Rogers HTC One X. Got Auto brightness, and auto sync on. Running AOKP ICS.
