Bluetooth on all the time, about ~100-150 emails pushed from BES, web surfing about 20 pages or so, mucking around with settings/ringtones/etc, about 10 phone calls, one which was about 20 minutes and the rest were shorter, MSN messenger in the background, six RSS feeds checking every 30 minutes, Facebook on, blackberry messenger, weatherbug updating once every 30 minutes, ~5 meeting notifications with vibration + sound, hotmail pop email, another POP email box, screen backlit brightness at 100, 8am to 8pm and had about 30% left to go.
Not bad, I was used to charging my bold 9000 every night. I should probably turn the brightness down and reduce the delay from 30 to 20 seconds. But I need bluetooth. I'm happy with the battery so far.
