I'm happy to report that battery life is very good. I get 1-1/2 days of battery life with rigorous testing. This includes using GPS while driving. Playing music with stereo headsets. Phone calls w/speakerphone on. Web browsing with Opera. IM with Beejive. Taking pics and videos.
In comparison, I use to get 1 full day with the Curve 8320. And that was without GPS.
Handsdown, the Bold 9700 has the best battery life of any cell phone I ever used. Good job RIM!
