When using the new iPad, just for casual browsing on wifi, it loses power even though it is plugged into the mains using the charger that came with it.

My iPad 2 didn't do this.

Has anyone else experienced this?

Then that wold indicate that the iPad 3 uses more power than the charger provides and you will need to turn off your device to charge it.

I have been using mine on and off all day and I am at 60% and very happy with the battery.
 
Yea I'm noticing similar behavior. I'm downloading GPS maps and leaving it plugged in but it's not quite up to keeping up the charge. That's the fault of the retina screen and extra cores.

Kinda of bad really, means that I actually have to go with periods of no use to recharge!!

I haven't had this problem with my iPad. Strange.

Sometimes when I'm using an in-car charger it may do that on my iPhone, (probably because the car can't provide the power or whatever)

Are you sure you're using the correct Wattage/plug? (I've sometimes charged my iPad with my iPhone plug every now and again)

But, if you're not.. See what others say. - Or go in to an Apple Store.

I'd wager that this is the issue as well. The iPhone can't always charge off USB current either. You need the 5W charger to get a guarantee that it will charge when using GPS. I could see the 3 draining on the 5W charger when under heavy load. I might just measure the power draw tonight.
 
I'm using the charger for it not just on USB. It's running rather warm too. Some chargers may be better than others...

In the original post I said it is the charger that comes with it. (10w iPad charger connected to mains with the genuine USB cable) not the iPhone charger.

It also seems to be getting quite hot just browsing this forum.
 
Mine was happily charging while I was browsing this site last night. I think something is wrong at your end.

I think you might be right... I left it to change over night last night and when I woke it was 100%... I have only been using the web today. All background tasks kill and just safari open. Brightness on 3/4. Wifi only. I used it down to 75% and then plugged the charger in and continued to use it. It has slowly gone down and down and now is on 64%. It also feels noticeably hotter than my iPad 2 did.
Im starting to think I have a problem?

Where is hotter? If it's in the bottom left could be the GPU/ CPU if it's anywhere else...the battery

I suspect all new iPads are like this, remember the battery is 70% bigger than the battery in the iPad 2. It seems like having it completely turned off while charging is the way to go.

Jason do you use it in your sleep?

Also what do you have the brightness set at?
 
Need a 20 watt charger or one of the dual port charges (both supplying 2.1 amps) that you can plug a 'Y' pigtail into. I have a couple of these cables that came with an external TV tuner and one from a USB external hard drive. Just need to find a dual port charger and an a USB-mini to USB adapter.
 
Were you restoring from iCloud in the background? Downloading files over wifi is fairly power intensive for the iPad.
 
I've got mine plugged in whilst browsing the MR forums. The charge indicator is still going up (now at 94%), though only wifi is on (BT and cellular are off).

Let us know if this set-up works for you..

I haven't had mine start to heat up except once when I was playing Infinity Blade. Usually if there is heat, there is a lot of power being consumed, which heats up the battery. It also explains why 10W isn't enough to charge it when this happens.

Might consider rebooting the iPad to see if you can get the heat to go away. It isn't normal when browsing. I've seen it happen before on iOS devices, and it usually goes away after a reboot.

Mine has gone up from 67 to 75% in the last 45 minutes of use. Screen at 3/4 bright. You have a defect and should just return it and get a good one.
 
I say it's due to badly optimized code.
When playing "Cut The Rope HD" he keeps charging - slowly but it's happening.
When playing "Tiny Wings" you start @ 100% charge and have it plugged into the power-outlet and he loses power - while getting hot due to charge and use.

I guess that apple needs to address this issue by some compiler-options that kill redundant GPU-cycles or something similar.
After all Tiny Wings is just an iPhone game and should require next to no 3D power at it's current state.

I started a similar thread to this this morning. I too kept my screen at 3/4 and noticed the drain. 3/4 was absolutley plenty on my iPad 2 so naturally I did the same with the iPad 3 but oh no, the retina is an absolute battery draining demon. I did a few more test and Im pretty sure my machine is actually Ok and not faulty. What you might have to do is get use to 50% brightness. It made a huge difference to me. The sweet spot seems to be:

iPad 2 3/4 brightness = ~10hrs
iPad 3 1/2 brightness = ~10hrs
 
Having the same problem except...

I'm having the same problem with my ipad 3 losing charge, and it doesn't not seem to matter which charger/plug I use. There are however 2 outlets in my apartment where this doesn't happen.

Any ideas about why this would happen?
