As most of you probably already know, despite having a 30% larger battery capacity, the Treo Pro only has a 10% better talk time than the 800w (though it does have a 25% better standby time).

In part this is due to GSM vs CDMA, hardware (333 mhz CPU VS 400 mhz CPU), screen brightness, and about a billion other factors. But a large part of this is due to the ROM.

I'm going through and diffing the Pro's ROM to the 800w's, and thought I'd share some of the tweaks that Palm has done to increase the 800w's battery life. This will probably be a fairly small list, but hopefully it'll make a difference.

I'm not specifically looking to increase the Pro's battery life, but if I stumble across something I'll share it. Hopefully other people can post their own tweaks to increase life.

Where numbers are included they are most likely in HEX. Where approprate I've included in the decimal number in parenthesis, so it looks something like:
"MinHeartbeat"=dword:00000HEX (DEC)

These changes assume you know how to tweak the registry and possibly other settings.

Increase ActiveSync Heartbeat Time:

Code:

[HKEY_CURRENT_USER\Software\Microsoft\ActiveSync]
"MinHeartbeat"=dword:00000384 (900)
"MaxHeartbeat"=dword:00001c20 (7200)

Default:
"MinHeartbeat"=dword:000001E0 (480)
"MaxHeartbeat"=dword:00000690 (1680)

(Hopefully) more to come......
