I'LL BE UPDATING THIS AS DAYS GO BY--SUNDAY IS THE FIRST DAY

For this test turned off Wifi, GPS, and bluetooth, put the screen brightness to maybe 20%, and my gmail account is set to check for new mail every 5 minutes

Light email and txt messaging. Just watching The Wire: season 5 on my PC computer.

Watched a couple youtube videos with 7 volume bars
total time maybe (4:12 - 4:28pm) 16 minutes -- battery level at 73%

Attempting to transfer movie file via bluetooth to Pre-- total size 352 MB
Pre says it won't connect (My Treo 700wx connects easily to my Lenovo X61t notebook)
The phone displays a message says 'searching for audio devices -- no devices found.'
I also tried connecting from the X61t side, and it says
"The pairing attept resulted in an unknown error. The reported error code is 0x80070057
*Contact your device manufacturer..."

I graphed my battery life against hours of time used:


You can see that on day 1 the battery was losing 8.6 % per hour, but on day 3 the battery loss had improved to 3.5 % per hour. What did I change? Well I logged myself out of gchat, gps is off, and I changed gmail to push instead of check every 5 minutes.
