    I just got my Treo 650 from Sprint last night, and I'm loving it. A huge upgrade to my 270. Though I got some conflicting data. The guy at the Sprint store said to charge the battery back up, but when it reaches 100%, to unplug it from the charger. The handbook, however, said to charge it overnight.

    Who is right? Does anyone have any bad stories about battery life going to hell due to overnight charging?

    Thanks in advance.

    Exactly! I leave mine on the charger overnight every night.

    You should keep it plugged in AT ALL TIMES! I carry an APC 1000VA UPS with me so I can keep my Treo 650 charging all the time. I get GREAT battery life, but I'm teathered to a wall or a 50 LB battery

    And remember: With the Treo 650, even if you kill your battery, you can always get a new one!

    My 650 is plugged into my custom cradle whenever I'm in the car or at home. No problems so far and my battery is always topped off. Who needs a second battery?

    Thanks for everybody's input. It'll happily stay plugged in.

With the quote that battery has a charge life of 300-500 charge cycles, once a day may only be one year of use. Every other day would ?double that.... I does warn against full discharge but I am not sure 20-30% would be considered full discharge.. thoughts?

    RTFM!

    Charge it whenever you can. The less you let the battery drain, the longer it will last. And you won't risk running out of battery late on that 2nd day.

    One of us misunderstands the meaning of a "charge cycle". My understanding is that a charge cycle is when the sum of the discharges totals 100% of the battery capacity, ie 5 discharges to 80% = 4 discharges to 75% and = 2 discharges to 50% = 1 charge cycle. At least, that's the way IBM describes it in their Thinkpad battery literature.

    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.

    Check the P1 support site at this link

    Pick any of the topics under How Do I...

    A new window will open with the topic you picked...from within this window...look at the top drop down list. You will find

    "How do I maximize battery life" pick this and you will se that P1 recommends charging overnight every night and topping off whenever your charger is near.

    Hope this helps.

    So, if one were to leave the treo on charge (like in a cradle) while you're using it, the battery does not discharge and it's life is prolonged?

    I believe so, within reason. Again, IBM recommends letting it partially discharge once a month or so. (Though that may just be a ploy to make sure that everyone has to buy a new battery eventually!)

    Cool! That's why I never had battery problems with the 600. It's always plugged into my custom cradle whenever I'm in the car.
