The new iPad runs hotter than the previous version, but it remains "comfortable" to hold in the hand, according to tests from a US consumer group.
Consumer Reports recorded top temperatures of 116 degrees Fahrenheit (47 degrees Celsius) while running a game - hotter than the iPad 2's top temperature by a few degrees.
"Using a thermal imaging camera, Consumer Reports engineers recorded temperatures as high as 116 degrees Fahrenheit on the front and rear of the new iPad while playing Infinity Blade II," reviewer Donna Tapellini wrote in a post on the Consumer Reports blog.
The temperature recorded by Consumer Focus is above Apple's recommended range of 35 degrees Celsius (95 degrees Fahrenheit) - but they're also well above temperatures recorded by other testers, including a Dutch website that said temperatures were hotter than the iPad 2 by five degrees Celsius and minor temperature differences recorded by CNet.
Our reviewer didn't find any overheating on the device, giving the new iPad a spot on our A List.
Indeed, Tapellini said the device didn't appear to be overheating. "During our tests, I held the new iPad in my hands," she said. "When it was at its hottest, it felt very warm but not especially uncomfortable if held for a brief period."
Testing
The temperature was taken on a single device after the game had been running for 45 minutes, with Wi-Fi left on but 4G turned off, and the Smart Cover on, Consumer Focus said.
When the new iPad was unplugged, it hit 113 degrees Fahrenheit (45 degrees Celsius), 12 degrees hotter than the iPad 2. While plugged in, it hit 116 farenheit (47 degrees Celsius), 13 degrees hotter than the iPad 2, the report said.
"The hottest areas weren't evenly distributed throughout the iPad's back, but were concentrated near one corner of the display," Tapellini added.
Apple's spokeswoman Trudy Miller previously told website The Loop: “The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus ten hours of battery life, all while operating well within our thermal specifications. If customers have any concerns they should contact AppleCare.”
