Someone mentioned 4 to 5 hours for a full charge for the new IPad, correct ?

How long does the Ipad 2 takes ?

Presumably since the battery capacity of the iPad3 is 70% higher than the iPad2 the charge time is proportionally higher.

If they use the same charger , yes..and apparently they do.

Someone said it will be similar charge times they just added more cels that charge at the same time as the others?

It seemed to be going slower to me, but I'd be glad to find out I was just being paranoid.

it's easy to know as the ipad3 has 44whr battery, and the charger is 10w, so even if the charger is 100% perfect, it will take 4.4 hours to charge. same for ipad2 it will be 2.5 hours.

Having 1 cell at 10000 mah or 2 cells at 5000 mah is the same thing and will both take the same amount of time to charge. If you increase capacity and keep the charge rate the same (as is the case with the ipad "3" charge time will increase. It doesn't matter if you do it by using larger cells or more smaller cells.

Thanks, interesting.
What if the charger has the capacity and they charge in parallel?

It does not work that way. Chargers are not perfect, nothing is.
