Streamed over 3G Data or over Wifi ?
3G While I drove from Cincinnati to Cedarville University.
I am at 9 hours from when I unplugged.
My battery is 13%.
9 hours of up time
8 hours 12 min of awake time.
I rode this battery as hard as I could. I turned off all power managing apps. I kept my entire PowerBar on the entire night (Brightness as full, Bluetooth on, Wifi on, 3G on, GPS on, Refresh on). I streamed Pandora via Bluetooth (Motorolla) over 3G for over 2 hours and 20 min (To and from Cedarville). I surfed the net and listened to Pandora for another 45 min while at Cedarville (still over 3G). I talked on the phone for about 20 min (several different calls) and sent/recieved 23 text messages. I actually downloaded and installed the multi-touch keyboard from another thread (it didn't work on my phone btw). I did all that I could to drain the battery as fast as I could. My facebook was set to update every hour, my Twitter was updating every 15 min. I manually refreshed my Gmail often.
All in all, for a first charge, not too bad. I'm sure that with minimal battery conservation and normal usage, I could have gotten more than 24 hours easily. I normally wouldn't leave GPS on all the time, nor would I have Facebook and Twitter updating that frequently. I'd also usually have Power Manager on as well. I'll update again after a few more charges.
One last thing. The pictures I've seen on here (of phones with the 2150) are ATROCIOUS. I almost refused my package this a.m. when FedEx brought it. Truly, it is not that bad. I can hardly tell a difference in my pocket. My wife has an Incredible as well, it was nice to hold hers in one hand and mine with the 2150 in the other. THERE IS A DIFFERENCE obviously, but not as much as you'd think. FWIW.
