Actually consistently running down lithium-based batteries, such as in the iPad, will shorten their life, not lengthen.

It's best to top if off when possible. But it is also good to use it regularly too. So if you don't use your iPad on battery power too often it is recommended to go through at least one charge cycle per month. Note that charge cycle does not have to be done at one time: if you charge it when at 80% then doing that 5 times would count as only one charging cycle.

Finally, there is no such thing as overcharging these batteries. The charging system is very well matched to the battery and will not overcharge it. If it did we would have iPads burning up left and right as overcharging lion/lipo batteries can be risky and dangerous. It quick-charges to about 80% then trickle-charges to 100%.

That's not true anymore with today's Li-Ion batteries, there's no longer a memory effect.

I never turn mine off either, except on the few occasions when the battery just goes down to 1% and it powers down on me. I plug it in immediately when this happens and count every second until it comes back up again.

Me too!! We are very much alike, woman! Except mine powers off at 2%.

Yeah thats boring me why i have to pay a longer cable for the ipad? With the standard cable i have to leave the ipad. Now i bought a longer cable its not normal guys from apple do ita in the box when i buy the ipad.

rarely, only when i'm charging via usb. i feel this helps it charge quicker?

Is this a trick question? Of course I'll use it when its charging if I want or need to.~~

I didn't know you COULD turn it off while charging, because when mine's turned off and I plug it into the wall, it turns back on. But I turn my iPad off multiple times a day when I'm not using it to stretch my battery life to 3 or 4 days, so I just leave it on (but in airplane mode, because I assume it charges faster that way; my Android phone does) when I charge it.

No not really I use the phone or read on my nook yes I love to read on eink
