I am on my second full day, without a charge, since the reg edit! I still have 40% on the battery meter. I talked on the phone a total of 56 minutes (mostly in evdo but on the road in the country so it did switch a bit i am sure) and surfed the forum(s) at least 45 minutes on cell signal and read the news on On demand the 3 times I "sat down" this is over 2x normal battery life during my normal usage and I still have 40%!!!!!!! I cant believe how well this worked..... I just hope that no damage or life span shortness comes of it......
