For those who experience New iPad heating issues (I hope this is useful to you, Steve jone, you may want to explain some of your usage trends like others did
Here are some tell-tale signs of defective units (heat related):
If your iPad loses charges too quickly and it's no where close to 8-10 hours of usage from full charge due to heat, you may have a problem.
The maximum heat threshold the iPad's battery pack is 35 celcius or 95 farenheits.
If the iPad itself is already producing more heat than what the device as a whole is able to withstand, it is a defect
I've personally made 2 exchanges, now on the 3rd iPad which I'm keeping. The first New iPad I had was a pre-order and I received it days after the debut. But I only got the satisfactory unit about 6 weeks after my first order....
Both unit 1 & 2 were having heat issues, especially while running Retina apps. The worst experience was running Infinity Blade 2 on the second unit, the amount of heat produced was an alarming temperature over 50-60 celcius.
Personal observations
Both units rejected by me were assembled in the Foxconn DL facility
I've also heard a number of reports on overheating, mainly iPads assembled in DL of which some people are claiming to have made several exchanges (talking about DL cases only, excluding DM etc..) and finally receiving a DY which was satisfactory. With just one DY received by these people, it ended the "musical chair game" immediately.
I'm one of them, the DY replacement unit met expectations. Heat itself was contained, it was operating near 35 celcius at most. Running high-end games like IB2, usual temps would be around 30 celcius. All in all, battery doesn't drain screen looks perfectly normal too.
So where was your iPad assembled? It seemed that there is a correlation between assembly plant and defect rates
Note: The first 2 letters of your iPad serial represent the Foxconn facility it was assembled at, if you're unwilling to follow the link to input your entire serial. Make your exchange ASAP if you're having a defective iPad.
Some others are saying heat issues may subside after running 2-3 charge cycles running the battery from 100%-0%. If problems persists, contact the retailer or Apple's toll free hotline.
