This is just not acceptable. I ran my New iPad (iPad 3) down to 10%. Then I turned it completely OFF (totally powered down) so there would be NO drain. I only turn it on for a few seconds every hour or so to see how it is doing. It is now 10 hours and it is only at 80%. That is 7% per hour. THIS IS NOT ACCEPTABLE. If Steve Jobs were alive he never would have released this product with the included charger. If your battery is 75% LARGER then you need a charger that has 75% more POWER! The iPad is MUCH more expensive than other tablets and we should expect MUCH better than this from Apple.
To all those telling us we should have expected it to take longer to charge I say nonsense. APPLE knew that the iPad 2 10w charger was not enough to charge a 75% larger battery on the iPad 3 as quickly as the battery on the iPad 2. DUH!!! Hello!!! Did Apple test? What happened to quality control? Some bean counter made a decision to save some money and we all suffer. Sorry, but I am ******! This greatly diminishes the usefulness of the iPad 3. The worse part is this is an EASY fix. All they needed to do is up the power on the charger? HELLO! (unless there is a desing flaw we don't know agout... the over heating issue?)
Apple needs to get new higher powered chargers out to all users ASAP. Having to take 12 to 14 hours DAILY to charge your device that only gets 6 to 8 hours of useable time is totally out of whack.
Apple are you listening?

Apple recommends to charge it overnight. That is what you get when we demand longer battery times and very thin devices. Face it, there is a minute difference in weight and size between the new iPad and the iPad 2, but an increase in battery size of 70%.
So yes, your new iPad will take between 10 and 12 hours to get a full charge. Don't like it, return it!
I do not know where you get 6 hours of up time. I am getting 9 1/2 to 10 hours. Now, I do not run everything at the same time, you know 4G, Wifi, bluetooth, etc.. No electronic device is meant to be run like that.

I have read everything. I don't understand why you would think I didn't. I'm just saying it shouldn't take 20+ minutes for the battery to charge up by 1% while in use. I could understand maybe if it only took about 10 minutes for the charge to go up, but 20+ minutes come on are you kidding me. Usually you shouldn't use your iPad while its charging, but even if it did charge at 1% every 10 minutes that's still slow.

Most people are seeing charge times of 5-6 hours when the unit is sleeping, not 10-12. A 10-12 hour recharge time indicates something is wrong. Might be the charger, might be the cable, might be the iPad. But, no, it's not normal.
As for the 6-hour run time, Displaymate measured run tims with the display set to various brightnesses-- at 1/2 brightness, they got a run time of over 11-1/2 hours. With the display set to maximum brightness, it dropped to under 6. Seeing as the display draws nearly 7 watts at max and the battery has a 43 W-hr capacity, that's not a surprise (although it is a bit of a shock).

You won't see a difference because your test is flawed. The iPad doesn't run any apps in the background. At all. An app can tell the OS to do a few distinct operations on its behalf after the app quits (like, playing audio, for example). But it's all managed by the OS. Having app icons in the app switching bar at the bottom (when double tapping home) doesn't mean they're running - think of it only as a recently used apps list only.

I wasn't performing any official tests, I'm just stating what actually happened with my iPad. Yes, I already knew that not all the apps are actually running in the background and that its more like switching to that app. However, I did have a couple of apps opened that was actually running in the background, for instance some utility apps and some games. I checked with my "System Status" app to see what processes were running. Regardless of whether or not my so called 'tests' was flawed I'm still getting 20+ minutes charge time for every 1% increase of battery life. That is simply unacceptle. I even tried no apps running with only the display on home screen without it sleeping/locked and my iPad plugged in with the OEM 10W charger/cable that it came with, still 20+ minutes per 1%. I will post a YouTube video of this and add a link to this forum tomorrow so that you can see what I'm talking about.

My iPad 3 takes a long time to charge as well...I'm thinking about taking it back to the Apple store to get my money back. My battery was 25% last night. I turned it off, put it on the charger and at 7am (7 hours later) it was only at 79%. That is ridiculous...considering this device cost over $500...
Steve Jobs would not be happy...

Up until a month ago I had the original iPad1. I used it a lot. I plugged it in at night and in bed used it until I fell asleep. In the morning it would be charged. I often left it plugged in while in the livingroom. I mainly used it on the battery when I was out of the house. Then my pad died and I ordered the New one. I got it on the 16th and I began to use it the same way. I discovered it heated up tremendously. It was way unconmfortable to touch. The charger also was very hot. So I would unplug it and take care.
Next I read on these blogs that the best this is to run the battery to 0 and recharge it. So I ran it down past 10% when I had to go out. I plugged it in thinking when I got back in 3 hours it would be pretty well charged. In 3 housrs it was 30%. It's now been 8 hours and it's about 80%. Ten percent an hour. I have to say, that while it wasn't plugged in and I used it it got barely warm. I use it at night. It will be hard to get the routine set to have it plugged in for 10 hours at a set up.
I love the thing. I don't want to take it back.

Try using the USB cable and charger that came with the new Ipad. I tried using some older cable with the new charger, and I only got 6-10% per hour. Using the correct equipment i get 15-18% per hour. Big difference.
Currently Being ModeratedMar 22, 2012 6:10 PM (in response to jimhanseng)
Try the correct equipment, it might help. I found that using the cable and charger that came with the new Ipad works.
Specific tests I've done:
old-USB cable + new 10W charger = 5-6% per hour = 100% in 16 hours
new-USB cable + new 10W charger = 14% per hour = 100% in 7 hours
old-USB cable + new 10W charger + Ipad off = 10% per hour
new-USB cable + new 10W charger + Ipad off = 18% per hour

I'm pretty sure i am using the charger and cable that came with it. i know that two years ago when i got my ipad1 that i didn't recgnize the difference between mi classic ipod and the ipad and charging with that was impossible... well, not really impossible. anyway I do know there's a difference between chargers. I am used to read that otherscharging times are better after they've run the battery down a couple of times. we'll see though.

To identify the iPad cable, it is a little thinner and has a longer rubber neck on both ends (about 1/4 inch long). There are a few posts already indicating the iPad cable and charger speeds up the charge time significantly.

Just to let you all know.
The new iPad has a retina display. The retina display was pretty much a dual layered screen, both with denser pixels, meaning that a massive battery upgrade had to exist to keep the ipad on the high end of long battery life devices.
Apple has used a 70% bigger battery which obviously means 70% more charging time for the new iPad.
If you use an iPad with 4G you'll recieve the same 10 hour battery life as the iPad 2 however what is positive to note is that the iPad 3 without 4G doesn't need the extra battery for wireless data but still uses the same battery as the 4G model providing you with a massive 13 hour battery charge.
Yes it takes longer to charge, but it makes sense. There's nothing wrong with the product. I charge mine when i sleep and use it for the whole day.
