“Much has been written about the increase in heat emitted from the iPad 3 [sic] with some tests claiming that it runs as much as 10 degrees Fahrenheit hotter — while running GPU-intensive tasks — than the iPad 2,” Jason D. O’Grady reports for ZDNet. “One of the loudest complaints came from the venerable Consumer Reports which claimed that the iPad 3 hits 116 degrees while running games — again using thermal images to support its case.”
“Apple was quick to nip this one in the bud, with Apple PR’s Trudy Muller telling AllThingsD: ‘The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus 10 hours of battery life, all while operating well within our thermal specifications. If customers have any concerns they should contact AppleCare,'” O’Grady reports. “Ray Soneira, President of DisplayMate Technologies Corporation, thinks that the “overheating” claims are overblown and I agree.”
O’Grady reports, “I played games on my iPad 3 for about two hours straight last night while writing a review of five games that push the iPad 3’s Retina display to the limit — and my iPad never got too hot to touch. It was definitely warmer than my iPad 2, but not unusually hot, especially for how much I was pushing the quad-core GPU and the Retina display… According to Soniera, the iPad 3’s LCD panel has 72-82 LEDs, which is approximately twice the amount of LEDs as found in the iPad 2. The iPad 3’s LEDs give off 2.5 times as much heat as the iPad 2 as will the battery and power electronics. He goes on to say that when the iPad 3 display is set for maximum brightness the display consumes about 65% of the devices total power, which plays a major roll in its thermal budget.”
