    I've been doing a little experiment. The background:

    - Butler running in background, nothing else. Phone service always on, BT always off, no data service at all in the first place. ROM is latest from AT&T (2.11, right?).

    - after charging all nite long, my 680 with the 1600 mA battery starts the morning at 95% charge (never understood that). After an hour of perhaps checking my calendar once and otherwise being inactive, the battery is down to the 80's%. I use the Palm for quick uses for but a few minutes at a time only a few times a day. By 5 or 6 pm, it's down in the 40's or 30% range, especially if I made a short phone call or two. If I work late into the night, it's in the 20% range by midnight. If I'm still working by midnight, it means I'm on labor and delivery waiting for a patient to deliver, so I won't be getting home to charge the battery for a while. At this point, I get nervous about it dying.

    - I had a vague impression that screen brightness had a big impact on the battery drain. I had this impression because before I go to bed, I turn the screen brightness way down. If I forget to brighten it back up first thing next morning, I have noticed the charge declines much more slowly during the day.

    - the interesting observation is that I use the Palm SOOOOOOO little (screen on literally probably 45 minutes or less per day total, 1-2 phone calls per day or less, BT never on), that screen brightness shouldn't be a big issue. AFter all, I should chew up battery power with a bright screen only if the screen is on a lot. But the screen isn't on at any brightness nearly all the time.

    So this has me wondering if the screen brightness setting, irrespective of actual PDA and screen use, has a lot to do with the fast battery drain issue.

    Anyone else notice this? Anyone else want to experiment with this aspect of the mystery battery drain?

    I think this is because the Treo stops charging once the 100% level is reached. It appears this charged "state" is reset by unplugging the charger and plugging it again.

    Heavy drain is discussed in several threads in these forums. Try a search for "The Glen Phenomeon" or the threads on PowerHero... you'll get a lot of information on from other users experiences and observations.

    Heavy battery drain is on my mind because of the rather heavy drain in my Centro... 50% in a few hours. There has to be something to spoil the party!!!

    Well on my stock battery I run 35% screen brightness (not a fan of bright screens on phones).

    Phone offcharge at 7am 99%, couple of alarms, 3 calls today around 35 mins in total, a BT hotsync, 13 SMS messages sent & several received. A bit of web surfing (like now) using a BT connection to laptop for about 20 mins.

    It's now 23.25 and battery just dipped to 70%. Loads of 3rd party stuff installed, you sure that battery working well?

    The stock battery that it shipped with does even worse than my 1600 mA battery!

    My phone without data connected and my wifes phone (never data connected) both would last 2-3 days without recharging with that sort of usage.

    What do you have installed? Maybe some program is misbehaving. BTW, my 680 is loaded with stuff and it'll last the same as my wifes who has only a couple of things loaded.

    Screen brightness has no effect on battery usage while turned off. Is it possible the Treo is on in your pocket a lot from keys getting hit or such?

    My Treo sits screenface-in snug and protected from inadvertent keystrokes by my Helix holster. The device is either in my hand being used a few minutes at a time a few times a day, or else it is in the holster. I am 100% sure it is not turning on in the holster. Sometimes when I'm home relaxing in the evening I take the Treo and holster off my hip and set it on a coffee table while I watch TV or work on the computer. I would notice it were being turned on by the holster or spontaneously.
