New iPad runs 10 degrees hotter than iPad 2

Tests show a significant running temperature difference, probably owed to the bigger battery and faster processor and graphics chip.

The new iPad generates an extra 10 degrees when compared to the iPad 2, according to tests performed by Dutch site Tweakers. Put alongside an iPad 2 under an infrared camera, the tests show a significant running temperature difference between the new iPad and its predecessor, probably owed to a bigger battery and faster processor and graphics chip.

The tests were performed using GLBenchmark for five minutes, after which the hottest point for the new iPad and iPad 2 was measured with an infrared camera. The lower right corner of the new iPad seems to be the hottest point, with a temperature of 92.5 degrees. The same place on the iPad 2 was around 10 degrees cooler at 82.9 degrees.

Tablet showdown: new iPad ('iPad 3') vs. Transformer Prime

ASUS Eee Pad Transformer Prime review

Apple sold more than 3 million new iPads over the weekend, and some tablet users already noticed the increased running temperature. On Apple’s support forums, hundreds of users noted their new device is running hotter, particularly in the bottom area. So much so, that some users report “the heat is near unbearable at times and makes my hands sweaty while holding it.”

A teardown of the new iPad revealed that Apple increased the battery capacity by 70 percent, but the battery itself is also 70 percent larger. Apple used the same dual-core processor in the new iPad, but upgraded the graphics chip to quad-core. So according to the teardown, on the lower right corner (from the back) there is only the jumbo battery, and not any chips (they’re on the left, running top to bottom), indicating the 42.5-watt-hour battery itself runs hotter.

If this is not a manufacturing defect affecting only certain new iPads, it seems the high-resolution Retina display, which keeps the new iPad as the leading tablet, has taken an even bigger toll than previously thought.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
