I decided that I would let my battery run all the way down so I could get a full cycle after the update. I heard about the increased battery life, and so far I have witnessed it first hand. I know most people charge when its in the red, or they get the 20% warning or 10%, but I have just kept going. So far I am on 1 day and 7 hours without charging, or connecting to my computer. I have email check on every 15 minutes, and I have: listened to music, listen to music on pandora, surfed the internet, text messaged over 20 times, watch a full episode of the office, watch 4 podcasts (all over 10 minutes long), played cube runner, werdle, cro mag racing, and installed 10 different applications. Not to mention I have made over 8 calls... Still not dead, try it and see what happens, just let it die and don't give up even if it warns you.
