    The lady at Rogers (major provider in Canada) said that you should charge you captivate while its off. These will help extend battery life. What do you guys do??

    I charge mine overnight (while still on).

    Not sure if charging while off would extend battery life...but it does charge the battery much much faster while the phone is off. Full charge in about 1.5 hrs from empty if phone is off.

    Since I use my phone as my alarm, I don't power off to charge at night. I just sometimes do it during the work day, to exercise/re-calibrate my phone's battery status apps...drain 100% and then fully charge 100%.

    This was my thought too...

    I'm not really worried about charging it in 1.5 hours at night most nights, as I just plug it in when I go to sleep, and when the Alarm goes off in the morning, it's fully charged.

    If I forget or need an emergency charge, I just swap out the battery with one of the e-bay spares I've got.

    I wonder what happens if you just keep switching in new, already-charged batteries each time your battery dies. That's what I've been doing, but not sure about what the effect is, at the same time.

    If you're turning it all the way off before pulling the battery, it shouldn't be any major issue.

    My battery life seems to be improving and I hardly ever turn it off...

    I charge my phone while it's on. I only turn it off to charge if I want it to charge more quickly.

    +1. Although I try to unplug it and turn it off if I should wake up and see the "full charged" message.

    The only thing I don't like (!) about charging at night is having what seems like a 100w bulb lighting up my room telling me my charge is complete.

    Easy fix...face phone down at night. I actually do that every time I put my phone down. I think it's a small but useful way to help protect the screen from freak accidents.

    I turn mine off at night, place it upside down, plug in the charger, and use my trusty old Nokia 6650 as an alarm clock.

    Oh snap! Didn't know that...I'll give it a try.

    I actually disagree that charing it while off will "help extend battery"

    The reason I disagree is that the charger provided with the phone will output a max current. If the phone is on, some of that current goes into power the phone, while the rest (minus some efficiency) goes into the batteries.

    So if the phone is on, the battery will charge slower (and this also makes sense)

    Now, most people know that charging a battery quickly is bad for the battery. If you charge a battery too fast, it can heat up past a safe point - which will doubtfully ruin the battery, but will surly decrease the batteries life-span (not charge, but overall 1-2 year lifespan)

    It makes more sense to charge the battery slowly, allowing the chemicals inside to react in a slow, stable way

    I turn my off and charge. 100% when I boot up. Leave it charging overnight while on and the phone cuts off from the wall charge when full and switches to battery. Want to start the day with a full charge.

    i noticed that this is sorta true.....when i charge it overnight while its off, it takes a bit longer for it to go from 100% to 99% once I unplug and use the phone. But once it does drop to 99%, the battery drain/battery life is back to normal. So I guess it does extend the life a bit but not a huge improvement.
