Initially was very happy with battery life as I was able to go a full work day without having to charge phone with moderate use. All of a sudden battery starting draining rapidly to the point that within 3-4 hours I was at 0. I hadn't done anything unusual with the phone with the phone. Only thing I did was add some music from computer. I read through GC tips for better use and I think I had most things in place. Only thing I hadn't done was restart phone. I did and it appears that it has taken care of some of the issues for me. I probably had something running in the background that I wasn't aware of. Simple and cheap solution that you should try if having issues.
