thats right i wanted to get behind what was draining my battery. i appplied all battery tweaks for the touch pro when i got the phone and made it better. i was off work today and decided to see how the battery last with the radio turned off(basically airplane mode)i used the phone to play games an mess with software on the phone that didnt require internet threwout the day. the battery on went down 1 bar in 12 hours vs battery usually gone in 7 hours of non use with 3 bars of service in my house. so the radio is the cause of rapid falling battery life. what would htc have to do to fix the radios?
