    I've gone from average 11 hours max. battery life to 32-35 hours with the following changes - each one contributing around a third of the increase:

    1. Switched off Global Roaming to just CDMA. Biggest change - almost doubled current bat. life.
    2. .90 release - added about 6 hours increase alone.
    3. Seido 1600 extended battery. This was the smallest but still added about 4-5 hours.

    Also, I'm down to about 1 crash every 3-4 days instead of more frequent. Did not do a clean wipe from .86 to .90 though I did for all previous upgrades. I have lots of apps like Weatherbug and launchers. Seeing average 38 MB memory.

    This is all based on moderate business use - 10 calls per day, push email, lots of web use on WSJ, NYT, etc. Almost no use of video/mp3, etc.

    The extended battery is not bigger than the standard battery, just lasts longer.

    The roaming changes cam be made under Options > Mobile network.

    Also if you are in the USA then you don't need to have the global roaming turned on unless you plan on traveling over seas most generally to europe and parts of asia.
