I removed the People widget. From the main screen, scroll right. Hold down the People widget and remove it. I was getting 10 hours daily off a full charge. Today I got up to 14. Normally I lose 10% per hour. In the morning, I was losing 5%. I was hoping to double my 10 hours and get to 20 but I did make it to 14. I was also losing 15-20% in the first hour battery drain. After removing the people widget, I only lost 3%! Previously, I tried everything. Turned off GPS, formatted SD card, hard reset, changed from GSM to CDMA, charging while the phone was off/on repeatedly. I have hardware version 003.
