I updated my phone 2 days ago and like all the changes. Everything is good except my battery. Before the upgrade I was fine with my battery. Everything was good. Since I upgraded to 2.2 my battery has been horrible. Just horrible. I thought this was supposed to improve battery life. Is this just a glitch or something? Someone told me that some people were having problems and there should be a change within 3 or 4 days to fix the problem. Is this correct or is my phone the only one that got worse battery life since the upgrade?
