The new iPad runs a little hotter than the previous generation, to the tune of 5 degrees Celcius or 10 degrees Fahrenheit, according to the site Tweakers.net. Using a thermal imaging camera the site has discovered that the case temperature of the third generation iPad tops out at around 33.6°C after five minutes of running benchmarking software, whereas the iPad 2 hit 28.3°C. Anecdotal reports from users are suggesting that the small increase in temperature is barely noticeable for most people and is generally much cooler than the heat output on the bottom of your average laptop.
Apple has issued a statement to the site The Loop which says “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.”
To put this in perspective, the new iPad will barely reach the skin temperature of a healthy person which obviously is nowhere near hot enough to cause an issue. However, given that Apple has produced a statement in response to this, they are obviously eager to ward off any unjustified criticism of their new product.
Generally, a new iPad that is slightly warmer than an iPad 2 is certainly not worth worrying about but, if you are concerned and any of your Apple devices get uncomfortably hot under heavy load, then contact Apple and get them looked at.
