This is my experience as well. I'm at 2 hours 0 minutes usage and 7 hours, 32 minutes stand by and i'm at 83%. I can go without charging for an entire day with moderate usage (5-6hours). Pretty impressive. Totally loving my iphone 5.

I was getting this with my previous phone using an extended battery. It was the HTC Rezound and that extended battery was huge. Made the phone heavy.

This replacement 5 has amazing battery life. I'm not sure it doesn't have a reactor inside:)
