Do you find the new iPad uncomfortably warm during your long gaming sessions? It’s not your imagination. Consumer Report testers have found that the new iPad reaches about 116 degrees Fahrenheit (about 46 degrees Celsius) when running action games, most notably Infinity Blade II. The temperature reading was done using a thermal camera and was taken after 45 minutes of uninterrupted gaming with Infinity Blade II, while propped up on an iPad Smart cover. When compared to the iPad 2, the new iPad was hotter by about 13 degrees Fahrenheit (which is about 10.5 degrees Celsius). Consumer Report also noted that the 4G connection was not turned on during the temperature reading, which we gather would have added quite a bit more heat to the whole shebang.
