Had my Razr since last Wednesday now and I must say I'm very impressed with the battery life. I had a DX and was always charging it and then had a GN for a week and that was just horrid .. This Razr is great. I used it all day with moderate use and want it to drop to 0% and charge it all night tonight and after all day it's at 40%. I've had the flashlight on for 30min now trying to kill battery and it's at 5% now.. When I look at the battery stats everything is right where it should be. The thing that really stands out to me is the OS system is 9% when I had GN it was like 30%. I hope this keeps up and I'll be a super happy camper !!
