    batteries don't "charge all night" so it doesn't matter if you leave it plugged in. It reaches a pre-determied state of charge and stops so as to not over charge.

    I also keep it pluged in overnight, but, in addition, I've purchased a cradle and keep it plugged in at my desk. I find my IM program (Verichat), which is on all day, and my e-mail program (Snapper Mail) are quite power hungary. I've had no issues to speak of.

    Please note: My spelling sucks and I'm to lazy to check it.

At least, that's the way IBM describes it in their Thinkpad battery literature.
    It seems jetkins, thankfully, that you are correct. I found a similar explanation in Apples iPod literature
    http://www.apple.com.au/batteries/

    Which means that there is no advantage to be gained in letting it drain before recharging - it's not the number of times you charge it that matters, but the number of times its total capacity is used.
    However, dispite some who have urged me to RTFM The BatteryLink below *does* mention that NiMH batteries *do* have a memory effect (as jetkins eluded to..) and should receive a full discharge every 3 months . (or 30 discharge cycles as mentioned http://www.powerstream.com/BatteryFAQ.html#nmh)

    [Edit:] Was pointed out to me link above is for NiMH and Treo has LiON batteries. LiON, also, need discharge cycle every ~30 cycles for longest life.

    Since the Treo has a lithium ion battery, info for nickel metal hydride is not relevant.

    Exactly. Something he would have picked up if he had RTFM.

    sigh.. Sorry about the misdirection. And thanks to those who so helpfully reminded me of my error I did post a link for NiMH batteries. However, that does not change my point. The link posted earlier recommends similar treatment for full discharge every 30 cycles for Lithium Ion Batteries.

    The only reason to try to dischage a modern Li Ion battery is to (re)calibrate the battery guage. A full discharge only shortens the battery life, so do this once when the unit is new and maybe afterwards only if the guage is starting to read inaccurately (maybe once or twice a year at most in many cases).

    I tend to do the latter, but not recharge overnight, is this a bad thing? I rarely get to 100% charged, but never run out of juice.
