Since I warranty replaced my incredible my battery life has been much better. I noticed that the phone takes a lot longer to charge, but it seems to hold it's charge much longer- going 8-14 hours between charges with at least 2-3 hours of heavy use. I have not put the last software upgrade (the one with all the bloatware) on this phone, and quite frankly, I'm not sure I want to. I don't want or need any of the Verizon apps that it adds. Would it be detrimental to the phone to leave this update off?
