I have the stock battery personally. Just posted about this over in the battery forum but, im just over 70 hrs since unplugged with 30% battery left under light/moderate use compared to most here. 4-5 calls a day out and 4-5 in or so, 10-20+ txts and an hour so of my daughter surfing/streaming you tube, not rooted, manually using ATK, launcher pro and other lil stuff, nothing special! Except when I charge it, I pull it off when its green, use it for a minute, and plug it back in, usually charges another 5-10 min 2-3 times. Hope this helps!
