This has probably been brought up a lot and beaten to death, but I felt compelled to make my own thread about this. I can't believe how much a factory reset helped me after installing Froyo. I finally got around to doing it this past weekend and one word....WOW! Not only did it fix a ton of little bugs that I noticed, but it literally doubled (or more) my battery life. I have the 2150 battery, but now I'm not sure I even need it anymore. I unplug my phone every morning during the week at about 8:00 am. After installing Froyo I was down in the 25-35% range by 3:00-4:00 pm every day. Causing me to recharge while I was at work just to make it through the night after work. Since I did the factory reset I have been getting stellar (by the Incredible's standards) battery life. Yesterday I went to bed at 11:30 pm and I still had about 50% battery life left. Granted I didn't do a ton of stuff on my phone yesterday, but I still used it moderately. As I'm typing this right now, it's almost 7:00 pm and I am at 51% battery life. But I did a lot more with my phone today. Anyhow, I think a factory reset should be mandatory on this phone after installing Froyo! If anyone is on the fence, I HIGHLY recommend spending the time and doing it. It's well, well worth it.
