The New iPad is Hot. Literally

It looks like Apple's new iPad runs a lot hotter than its predecessor, thanks to a beefier processor, bigger battery, LTE antenna, and other factors. Apple says the thermal specifications of the device are on target, however.

In the scope of things that could go wrong with a consumer electronics device, this is probably on the mild side. After all, Apple's iPhone 4 shipped with a list of hardware defects so long, just covering them all accurately was difficult. And don't get me started on the Xbox 360, which should win a Guinness record for "world's buggiest consumer electronics device, ever." The word endemic comes to mind.

But back to the new iPad. According to Tweakers.net, the new iPad runs about 10 degrees hotter than the iPad 2, about 92 degrees (F) vs. 82 degrees for the iPad 2. Consumer Reports, more famous for not recommending the iPhone 4 than for its decades of consumer advocacy, is reportedly investigating. We await their ruling from on high.

In the meantime, Apple says anything up to 95 degrees is fine, and if you read Laptop Magazine as I do, you know that 95 degrees is the limit for what's considered comfortable, heat-wise. So 92 degrees doesn't seem horrible to me. I'll need to test that though. 

So far, I've not noticed this issue personally. But I'm going to play a few HD movies today and see whether its noticeable; that's about the only "grueling" task I'll ever put the device through anyway. My guess is it won't even sweat.

Good thing you got that linkbait in before you find out it's a non-issue...

It definitely runs hotter than previous iPads. This is to be expected, a more powerful GPU, which is necessary for the screen upgrade, is going to generate more heat. This is true on other form factors as well - Apple actually lowered the clock speed on its second generation Macbook Air in order to run cooler, and the more recent models, with i5/i7 processors, run hotter than the Core 2 Duo models. The need for a much bigger battery in the new iPad shows how much more power is required. This is an issue that all tablet manufacturers are going to have to deal with, and the more complex the operating system used, the more of a problem it is going to be. I suspect that in most cases, the best compromise might be not to have such a high resolution screen.

I was at a Best Buy on Saturday. The Best Buy and the Verizon dealer I went to both had them in stock even at 6pm that night. The demo iPad 3 at Best Buy was noticeably hot in one area on the back. Maybe due to the demo program it was running? Dunno, but my iPad2 doesn't ever really get hot no matter what I do with it. The new screen is amazingly crisp, however I'm happy to wait for open-box returns and refurb'd units to show up at a discount before buying. Yes the top shelf iPad's do cost almost twice as much as the average PC laptop. Which is so hard to believe given the average $400 laptop's immaculate build quality and beautiful display.

I thought the whole reason for releasing new chips so far apart using smaller die manufacturing processes was to reduce energy consumption, i.e. reducing wasted energy, in the form of heat.... Are you saying that the manufacturing processes for Apple's iPad chips hasn't changed over the last 2 years? Also, I have to laugh at this: "Which is so hard to believe given the average $400 laptop's immaculate build quality and beautiful display." (obvious sarcasm is obvious) I'd rather be looking at my Lenovo system. It's actually $100 more (same price as an iPad but has 20x the storage), is more rugged than an iPad (it CAN survive a drop), doesn't cost me another $50-100 for a hardware keyboard, and does far more. Not only that, but it has an anti-glare screen, meaning I can read far easier on it than on an iPad. Oh, and screen isn't covered in smudge marks, and I can replace the battery whenever I want.

Question: they use the aluminum casing as part-heatsink right? Why don't they make the aluminum that is close to the processor thicker, and create a cavity in it so that the chip is totally encased in aluminum from the case, instead of just touching it with a heat spreader pad? Heat isn't going to spread perpendicular to the surface of the chip, so why not encapsulate the chip in part of the casing?

This be a linkbait piece Mr. Thurrott. Summary: 3rd party informs of heat change from iPad 2. Heat change is still within acceptable design range. Haven't bothered to test personally before writing. I agree with commenter "Andrew Schultz". A fan of your work - just had to agree with Andrew here.

You can be silly all you want about "linkbait." It's not that at all. The new iPad does run a lot hotter than its predecessor. It just does. Is it an issue? No it seems like a small thing compared to the iPhone 4 problems, but these things will show themselves over time, not immediately. Which I wrote. So grow up, people.
