i think it's more of a Power consumption > Charging speed issue.
we all now knows that the supplied charger charge like a slug...
and the flashy new hardware, gfx, 4g, and screen are eating up the power like mad.
some ppl have suggested to turn off 4g from settings and lower brightness to reduce power consumption...
and many ppl have also pointed out that a product should never be designed to LOSE power when being charged via a mains power charger!!!
i am not a eletronic genius, but i think apple has electronic design flaws at least on the charging part since some ppl have pointed out that the ipad3 actually drains quicker when being plugged into mains!! LOL which might have been due to ipad3 auto switch to turbo/bright/100% speed mode when being charged.
i have canceled my order for the new ipad3 which is due to arrive because i read the clauses, in the event that I opened the box, they will charge me 25% of the purchase price if I am not satisfied with the now known not so chargable IPAD3, OR they will charge me 13-15% (cant recall) as restocking COST if I didnt open the box at all after receiving the IPAD3. APPLE is DEVIL... this is so not right!!! why the heck would I want to risk buying a known defect IPAD3 while end up paying money for acting as a lab testing white rat...... this is totally insane... if the same thing happen to iPhone 5, APPLE will no longer dominate and will instead bankrupt.
