I just keep mine plugged in all the time (I have a stand for it at my desk). Is this bad? Been doing it for about a year.
 
That is a common misconception, the convention that you can overcharge a LithIon battery.

The iPad's power management will determine when the battery will be charged when it is plugged in. Once the battery is topped off, charging will stop and the iPad will switch from battery power to line power.

Unless you have a faulty iPad, you will never overcharge/kill the battery.


I'm glad that everyone else has great luck with that sort of thing. And I'm glad the facts don't back it up. But the only thing that matters to me is first hand experience. So I go with that.

Interesting, you must have first hand experience with NiCad and NiMH batteries.

This says it all in regards to LithIon batteries...

Basically the more deep cycles you go thru (draining all the way down then recharge to 100%), battery capacity goes down drastically as apposed to charging at 85%.

Nightly here. I use the thing non stop otherwise I might wait until it hits around 10-15.
 
I have had to charge it once since i got it. I plugged it in at 40% yesterday morning. Down to 65% now. Ill probably charge whenever it gets down to roughly 25-30%. Amazing how great this battery life actually is.
 
Depends on how it was used. Usually it takes a few days before needing to be plugged in.
