HTC Touch Diamond (CDMA)
of course since i was like a caged animal the whole time it was charging as soon as i started playing with it... i went crazy...
downlading music, testing the tv, testing the gps, teeter is addictive as hell (but far too short)
and the battery died... i wasnt surprised ... i was really pushing the thing...
so i charge it overnight and head off to work the next day... i didnt have time to fiddle with the phone that much until about 3 that day and had been using my mogul for texts and calls... not being used at all from 8 till 3 it exhausted 75...
In the weather application, default setting is to download weather automatically. Unclick it so that it only connnects to data to download weather when you press the update button.
Change your email settings to send/receive after a longer period of time. Or just when you manually press the button. Because it will connect less to get your email, it should help a lot.
Lastly, default screen setting is set to brighten and dim per the light sensor. You can disable the light sensor and set the screen to the brightness you prefer.
Hope those helps.
Also, I know some people have been saying ...
