i just recently purchased a motorola droid razr and while im loving it im dissapointed to see my battery life go straight to 50% within an hour of web browsing on 4g and dead in 2 and a half hours. Really dissapointed while i hear it can go as high as 10 hours with 4g off but why by a 4g phone to use only 3g anywho.Anyone else having a similar issue with the battery life?
