besides reading what others have said, my first hand expirience with NAVI+Pandora+E-mail checking, about 10 minutes of phone conversations and screen is VERY bright (sunny day). jumping from roaming/to sprint towers I was able to get ~3:30 before i got 15% warning ( running factory rom and no ATK).
in comparassing; THE SAME route with TP i wuld be using Google maps, playing MP3 i would get even less life and result- i'll be swapping spare batteries since TP would get too hot and would not charge....
EVO plugged and charged for the rest of my 6-hour trip...
heavy use i can see ~ 4 hours ( got 2 wall chargers and 2 spare batteries and car chargers)... just plug it in!
tp sucked when the signal is weak and 1x... drains a fresh battery in 3 hours just sitting on my desk, will see how evo does tomorrow
