I did the OTA Froyo update last week. Ever since my battery life has been awful. The first day after the upgrade the phone barely went 6 hours before dying (used to go all day with about 30-40% left). My phone was only about 60% charged when I did the update, I read somewhere that that may be the problem. I have looked for other posts with the same issues and have come across 3 suggestions. 1. Run the battery down to empty and recharge fully a few times. 2. Root the phone and run a battery recalibration app. 3. Hard reset. I've run the battery all the way down and recharged 3 times now. It has gotten better, but it still is not close to the pre-Froyo performance. It will now make it a whole day, but only with very light usage. I am going to run the battery down once or twice more, but if that doesn't work I am going to try something else. So, what is the better way to go? Root and calibrate or hard reset? I have not had any other major problems with the upgrade (no camera issues, no SD card issue, 2 apps needed to be reinstalled, otherwise no issues), so I don't really want to do a hard reset unless that is the best option. If I need to do a hard reset is there anyway to backup the phone and the restore the data without losing all of the apps and data (in the apps)?
