I dont know what the battery percentage is since i am on a 3G, but the 2% warning did come up already. And as most of us 3G users know, the 10% warning doesnt always come up. (well for me it doesnt). So it is possible that it is below 10% here. But my question is, is this good battery life. I think its safe to say that those 3 Hours and 47 min have been of strait safari use. So i dont really know if this is great or just average or just bad.
