I have had my shiny new iPad plugged in overnight with it's included iPad charger (it was displaying some context for some of that).
I have just woken up and it's only at 39%!!!! Now I know that it's meant to take longer to charge but that is unbelievable!?
As I said I'm using the lead and charger it came with, the only exception is I'm also using a usb extension lead inbetween as the plug is quite far away. I used the same lead with my iPad 2 every night and it charged fine and fast.
It also kept displaying not charging when plugged into my PC (which is definitely high powered ports).
Should I be booking a genius bar appointment do you think!?
Mine does not take that long to charge! I would take it in. I use an extension cable as well, and still charges mine. You may want to try another extension cable... My iPad literally shuts off, while plugged in and charging. I can't believe I cannot use mine, even while plugged into its power adapter, even if I'm still using it around 1-2%...
Just curious, does yours die while plugged in, while using it?
Wondering if I need to take mine in ad well...
The new battery is rated at 42.5 Watt Hours. So if the runtime is 10 hours then this means the iPad consumes 4.25 watts. It would consume more if it's running processor-intensive apps. Presumably there is some inefficiency in the charging process. Even so, at least from a layperson's perspective, it seems a 10w charger should be sufficient, even if the iPad is in use while being charged.

This is a genuine issue and needs to be addressed.
Yesterday, launch day, I received a white AT&T 32GB 4G version, but I found the color distracting and AT&T lied to me and I got no signal at all where I live. I was actually able to take it to my local store midday and exchange it for a black Verizon model. The Verizon is screaming fast.
Anyway, they both have the same charging issues so this is a definite problem with all iPads, or the iPad chargers supplied. I believe Apple will have to send us all replacement chargers. While using my iPad, even plugged into the 10W charger and with the cellular data radio turned off, doing nothing more than typing on this very forum with all other apps closed, the battery drains at a rate of about 5% every half hour.... WITH THE CHARGER PLUGGED IN! The charger is active and the lightning bolt battery icon is up there. The iPad will only charge when the device is fully powered down. Even if it is in standby the unit will not charge when plugged in. This is either an OS bug that needs to be fixed or the charger supplied is not nearly adequate.
The iPad charger will charge my iPhone 4S rapidly, even when in use. It also charged my previous iPad 2 in a decent amount of time. But this 10W charger certainly does not charge the iPad while on, and the iPad certainly does not get 10 hours of use with or without the charger plugged in,
This is a serious issue and one that needs to be address promptly. Apple needs to send us all higher wattage chargers, issue an OS fix, or take care of whatever the problem is.
They also obviously didn't think the new iPad development through. The unit gets quite warm when in use and quite hot when the cellular is on. Also, the display does not get as bright as the iPhone 4S, and several people at the Apple Store agreed with me on all these issues.
Unless Apple wants to see a lot of returns and unhappy consumers, they need to fix this issue pronto. In the time it's taken me to type this post the power has gone down another 3%, with the charger plugged in and supposedly charging. Something is seriously wrong here.
There seem to be a couple of issues here.
1. Any long extensions to the charger will reduce the efficiency of charging. This is true for any IOS device I have ever had (lots of them)--so try to use the cord it came with. I am able to get reasonable charging with this and it will still charge, albeit slowly, if Im using the device. I am able to go,so far, from a 40% to full charge in 3.5 hours.
2. If charging, I would turn off all radios and sleep the ipad. So, if you leave your cell radio, wifi radio, and bluetooth radio on, you will not charge quickly. For the definitive charging test, power off your ipad and charge.
3. The battery does condition itself after a few cycles--and while this remark is OFT, I've noticed that since first use on friday ( I have the wi-fi only version), there is almost no heat now when Im using it. I just watched an hour of hbo-go, no heat at all, and a discharge of 9% for the hour, so the battery life mark if just about right. This was not the case on friday.
From watching the comments on this group for the last few days, it looks like people are all over the map with problems and issues--I would give the device a weeks use before coming to any hard conclusions.
Sorry, I forgot one thing- this is a reply to the orginator of this thread--there is no possible way ANY pc or mac based USB port, hi power or not, thats going to charge this thing at a reasonable rate. So, I would think that for all of us with the new ipad, we will be looking for the highest power third party charger that the ipad will tolerate without burning up the batt.
Mine is just very slow at charging I have been charging it since 17.00 and it's now only at 77% it appears to be slower than the iPad 2 was through a standard 5 watt USB cable at this rate it's probably gonna take 10 hours to charge!
I get that it should take longer to charge being a bigger battery but this is too long.
I don't let it get that far so I couldn't tell you. I never let my devices get lower than 20% and even then that's rare. When I'm home I almost always left my iPad 2 plugged in while using it and I plan on doing the same thing with the new iPad.
The extension cord makes no difference. I still have the same charging issues with or without the extension cord. I'm using a 10 ft. Amazon.com Basics USB cord for both my iPhone and iPad. I never had any problems with them in the past either.
Sometmes when the new iPad is in standby it will charge slowly but most of the times it won't, and it never charges while I'm using it. The power always drops. In fact, I think the power drops more when the charger is plugged in then when it isn't.
My new iPad 3 wasnt charging at all using the 10 watt charger. Not sure but it may have been due to not plugging into iPad all the way or not making a good connection. It had the lightning bolt indicating it was charging but after having it on the charger for several hours nothing. I then moved it to my USB via my MacBook Pro and it charged at what seemed to be a great rate.
