From what I remember, it seems that devices are usually 75% or so charged. But PLEASE PLEASE if you can, charge it fully before you use it. I have heard in the past that draining a battery that has never been charged before overcharging it for the first time lowers the max capacity for the product. Ex: If you do this your "max" charge may only be 85-90% of what the battery was originally capable of. I did this to my 5G iPod Video back in the day.
All in all if you can, overcharge it the first time before draining the battery.
Sounds like something that someone pulled out of his anus. Old Ni-Cad batteries had issues with charge memory. They would learn to hold only as much charge as the user requested of them. If you discharged them only by 10% capacity before a recharge, then they would learn to hold only 10% of their rated charge capacity. A deep discharge, however, would restore the battery's capacity. You avoid memory issues with Ni-Cads by avoiding a set pattern to their usage. Ni-Cads could also explode, but I digress.......

That's Ni-Cads. Apple does not use Ni-Cads. Its batteries have a recommended number of charge cycles. They are not adversely affected by patterned or shallow-discharge cycles. Modern batteries don't give a flip if you don't top-off their charges before first use.

well ni-cad is the the only batteries it applies to, nevertheless.
I guess the iPad will just go off when there's only a few percent left, just like with the iPhone.Actually Lithium batteries do have a form of "reverse memory" to NiCd's. It is best to keep Lithium as close to fully charged as possible because crystals grow in dead cells and permanently limit the amount of charge it will hold. This is unrelated to the device being new but you should always and often charge your device to maintain battery life with one exception. Because of their volatility Lithium's have complex monitoring systems to keep from over charging (unlike NiCd that fill up with energy and stop, Lithium's will charge until they have so much energy they can catch on fire or explode). About once ever 1 to 3 months you should fully discharge to help keep this in sync. other than that you should if at all possible never let your battery fully discharge.

Thanks for the heads up wasn't aware of that. Do you mean fully discharge as in that 5% that os x informs you say of the impending battery drain, or 0%?
I would say as much as possible. Like the poster said though, only once every couple of months is necessary.
No such thing as a silly question.
Hope this was helpful.![]()
Oh Jesus, don't say that.
Knowing the people in these forums.........
It works off the AC power. You can use it while it charges.![]()
The batteries in the iPad are not replaceable.hmmm.... i guess i'll just do whatever works.
(and save $99 for a battery replacement in a couple years!)
