I got the extended battery, but I wanted to do a drain on the battery to calibrate it and to that memory dohicky thingy. At about 1030 am I was at 67 percent (was using the extended battery previously) I was in wifi and in 4G and 3G areas all day. Just did normal things in and out the house. Moderate downloading of apps on and off wifi. Internet usage and MP3 downloads off wifi. Drove miles across the city and went from 4G to 3G areas. Watched youtube and break.com videos on and of the wifi and 4G. Texted and made a few phone calls outside of wifi. I did alot with the phone. My battery finally decided to totally die at around 830pm. So, I don't have a million widgets running. Weather updates only when I prompt it to. E-mail get checked every 15 minutes. With all that I believe I got a god deal of battery usage. And it took me a short time to charge it fully. I wasn't counting, but I believe it was close to about 1.5 hours of charging. With that said QUIT RUNNING A MILLION WIDGETS! While you phone is not being used, why do you need facebook widgets running. Press a button and update, same with weather. You only need to know it when you actually look at your phone. So press the button and update it. I only plan on using my extended battery on long road trips or when I know I'll be out for a looong time.
