Consumer Reports – a popular product review and comparison site have also confirmed that according to their tests, the new iPad runs significantly hotter than iPad 2. In fact, their iPad 3 reached a temperature of 116 degrees Fahrenheit while playing Infinity Blade II, which is more than the operating temperature limit on the new iPad’s tech specs page.
Some users have been complaining on online forums that their new iPad feels a lot warmer than iPad 2 after extended usage. Apple had responded to the new iPad heating issues claiming that the new iPad runs well within its thermal specifications.
But Consumer Reports doesn’t agree with Apple, it Reports has provided the following details on their blog:
We ran our test while the new iPad was propped on the iPad Smart Cover, plugged in, and after it had run Infinity Blade II uninterrupted for about 45 minutes. The device’s 4G connection was not turned on, though its Wi-fi link was. The ambient room temperature was about 72 degrees. (Apple recommends not using the iPad in environments over 95 degrees.)
We also ran the test with the new iPad unplugged. Then we compared the temperature of the new iPad to that of the iPad 2 using the same tests.
When unplugged, the back of the new iPad reached temperatures as high as 113 degrees Fahrenheit. It was only when plugged in that it hit 116 degrees. The hottest areas weren’t evenly distributed throughout the iPad’s back, but were concentrated near one corner of the display as shown in the images taken from the rear of the device above.
Consumer Reports does note that even though the new iPad runs hotter than iPad 2, “when it was at its hottest, it felt very warm but not especially uncomfortable if held for a brief period.”
It remains to be seen if this issue will snowball into a controversy like the iPhone 4 antenna issue.
Consumer Reports also found that the iPad wasn’t charging while playing Infinity Blade II. A MacRumors forum member had observed a similar issue:
It will not charge under a heavy load.
The 10W charger is just not powerful enough. The Air uses a charger that is 4 times larger for a battery of near equal size.
Does your new iPad feel warmer than iPad 2? Have you noticed the charging issue under a heavy load?
