New iPad Runs About 10 Degrees (F) Hotter than iPad 2 [Updated]

[gatortpk]

Cancelled my order in light of all this "yellow screen" and "runs hot" business. Just went through a mess of manufacturing defects with the Transformer Prime, not interested in going through this again. I'll wait for you early adopters to weed-out all the quirks first

Well that was a mistake, considering the screen temperature is accurate (it's not supposed to be blue) and the iPad doesn't run hot (mildly warm in the lower left corner, sure).

I agree, that was a mistake. The new iPad doesn't run hot, and the "yellow screen" is rare. The Transformer Prime defects were so bad that there is a Class Action Lawsuit. There is no way the new iPads will have any of those same defects that warranted a lawsuit, and I doubt that any future equally impressive hardware (if ever this year!) for Android software won't run warmer too.

If you're waiting for these "quirks" to be worked out, then you'll likely be waiting for a new model next year, and that model may also run "warmer" too. In other words, there is nothing wrong with the new iPads, (except for the rare "yellow" screen, in that case, you should easily be able to exchange the iPad for a new one on the spot)

Instead of likely getting a perfectly good iPad now, you'll be waiting another little while to get one when you realize your (Transformer Prime experience) fear was unwarranted.

I think this whole issue is a bunch of hot air.

Being a cautious consumer is a mistake? Today I learned...

There are over three-million new iPads already in consumer's hands; deciding to cancel one's order based on the observasions of a handful of technology hypochondriacs is being overly cautious. The warm corner found on the new iPad is not a manufacturing defect; it's just something iPad users will have to become accustomed to as the iPad as a product continues to gain higher-performance graphics and processors. And regarding variation in screen color temperatures, with different manufacturers in the mix you'll be just as likely to get a too yellow or too blue screen 8 months from now as you will today.

In light of all that, the fact that your product is under warranty and includes a 14-day no questions asked return policy means that should your iPad have arrived with a screen too yellow for your tastes or a corner too hot to your liking, you simply could have returned or exchanged it. But again, the chances of receiving an iPad that suffered any issues at all would have been very, very low.

I can't imagine not having my new iPad right now just because a couple people on the internet couldn't handle that the lower left corner was 10 degrees warmer than their previous iPad. Because again, it's still 100 degrees cooler than a MacBook Pro!

I was at the best buy store in Roseville Mi. and came up to the ipad 3 display picked it up and right away I noticed it was HOT! I said to the apple guy in the black apple shirt, "THIS THING IS HOT"! He said "It's probably the alarm wire on it"... I said, "no way man, it's the ipad'! I hope apple knows about this! Could spell out trouble here! Makes me wonder how they do there testing? I hate when I got my laptop on my legs and how I get very warm from it. Dislike.

An Apple Guy at Best Buy? That's cool, I haven't seen an Apple rep at my Best Buy.

But anyhow, I hope he didn't say anything like "it's probably the alarm wire", that's not smart or likely. I would hope that the display case where the iPad was sitting in is what's warm, causing the iPad to be even warmer. Still you have to admit, laptops get warmer, or even hot! If an iPad feels warm, then marvel at the huge battery providing all that energy to produce that warmth all day.

I went to the shop on Friday to buy New iPad. There were three New iPads and one iPad 2 on the display. When I took the New iPad I immediately noticed how uncomfortable "hot" it is. I asked the seller about this issue and he said it is because the new display, higher battery etc - anyway, reasons that most of you state here.

There is however something that is called user experience. And my first thoughts when the New iPad was in my hands were negative due to heat. Then I took the New iPad in one hand and iPad 2 in another (both from the bottom, laying flat on my hands). The weight difference is noticeably. The experience of feeling the new device is unfortunately much worse in hands than it would look like from the theoretical negligible difference.

I bought New iPad for a gift finally but not for myself as intended, as I was simply disappointed with the experience I got after having iPad 2, which is still a perfect device, except the screen resolution that stands out on New iPad.

Being Apple fan I must say that Apple has disappointed me on this one. But if you are in Alaska, you might really appreciate the extra heat produced by New iPad.

PS. I don't keep MBP in my hands for hours (who does?), so comparing it to iPad is not right. If I would like to keep MBP in my hands for reading books, I would not buy the iPad. If new hardware that is used is producing too much heat, Apple should either find a middle spot in implementing such hardware or find a way to decrease the heat to preserve user experience from older versions...

I totally agree! I just made a similar post about that ridiculous comparison to the defective Transformer Prime. I did mention being able to exchange it on the spot in the rare event of a "yellow screen", but I didn't even think of the 14-day no questions asked return policy. Even more reason why canceling an iPad order based on "Transformer Prime experience" fear is ridiculous!

Another thing I think people need to keep in mind is that if this added heat is attributed to the screen brightness, then in-store display models with the brightness set to max all day are going to feel considerably warmer than how it would feel in real world use. No one is going to have their screen brightness maxed out at home. This is very akin to how tv displays in stores have all of the brightness and contrast settings set to the max; you wouldn't pass on a television purchase just because the store model that's been running for 12 hours with the settings maxed out feels like an open oven when standing next to it.

I've been using my new iPad most of the day, and the lower left corner is nothing but slightly warm. Screen brightness is a very comfortable 50-60%. You know, like a normal person would use.

Different strokes for different folks, I say. Obviously, we spend our money in different ways. Personally I can't wrap my head around chastising a consumer for not spending their money, but if that's how you feel

If you scan the Internet forums before making an electronics purchase to look for possible issues, you will never buy another electronic device for the remainder of your life. There will always be defective units for any product, or over-paranoid people who think they have a defective unit, and those people all turn to online forums.

Three million new iPads have been sold. Of those, a couple people got a defective yellow screen, and after reading those reports a half-dozen others think they got a yellow screen because they don't know what a properly calibrated screen (which the new iPad has) is meant to look like (not blue).

Likewise, of the three million iPads sold a couple people might have gotten defective units that run too hot, and after reading those reports a half-dozen other people think their iPads run too hot simply because they're 10 degrees warmer than the previous model. And then another dozen people think the new iPad as a whole is defective because the store model they held whose brightness had been set to maximum all day while the battery was fed a never-ending charge felt downright warm compared to the iPad 2.

Just order your damn iPad. You'll love it, it won't have any issues, and if I'm wrong Apple will take it back no questions asked

The wife said it was also heavier than her iPad 2 and wanted to wait for the next iPad.

Nothing wrong with hot and heavy.

How that might apply to consumer electronics, well, that's something else.

On a much more serious note, I noticed in a few breakout videos and also this forum in threads like this one a minor concern about the slight yellow tinting of the display panel due to the curing of the digitizer adhesive. I wonder if this heat is playing a role in exacerbating that issue, or maybe even assisting in a faster cure, if possible with the slight increase in temperature?

Things I think about when I can't get to sleep. I know, it's pathetic.

 

[baryon]

Well, if you think about it, the iPad has the processing power of a normal computer 3-4 years ago. Back then, those computers came with a fan or two, while the iPad doesn't. I guess it's totally normal if it gets a bit hot, though 34ºC is hardly "hot". My MBP goes up to 70º and it's totally bearable. I prefer a fast machine than a cold one.

 

[Jessica Lares]

My old MBP used to get to 120 F... It has to do with how Steve Jobs didn't think his computers should have ventilation because of dust and other junk that could get in there. You'll find that the aluminum design will make it super cold once you turn it off for awhile though.

It'd be a bigger issue if it got hot when just surfing on Safari, going through pictures, and doing really simple stuff like iBooks. At the same time, it's probably more of a developer issue.

And now that I think about it... Maybe it's because people are multitasking too many things at the same time?

The accepted range of "normal" human body temperature is from 97F (36.1C) to 99F (37.2C)

Well considering you are a MacRumors "newbie" I am seriously considering the validity of your post many "newbies" such as you have posted anti apple.If you were a regular or member then I wouldn't think about it....

 

[axual]

This is because ...

This is because the new iPad is hotter than the old iPad. One would expect it be warmer.

Do I get a prize?

 

[ph00ny]

Higher spec device running warmer than previous in a similar packaging? You don't say :gasp:

I wouldn't worry about getting injured playing with the new ipad but i would worry about battery shelf life. Lithium Ion batteries do have some high range operating temp but prolonged exposure will definitely impact overall capacity in the long run

 

[Renzatic]

It's not the heat, people. It's the humidity.

 

[kimlo]

The ipad (3rd Gen) has a 42.5-watt-hour rechargeable lithium-polymer battery
the ipad 2 has a 25-watt-hour rechargeable lithium-polymer battery

Both the ipad 3rd Gen and ipad 2 last the same amount of time on a charge. the ipad 3 would HAVE to get hotter, because it's burning through power at a higher rate. It HAS to run hotter with the same heat dissipation mechanism. iPad 3rd gen uses 70% more power than the ipad 2.

Can I get an iPad 2 with a 42.5 watt-hour battery so I get 15 hours of use?

Well how much heat does an LED backlit display generate? I don't think screen brightness causes anything more than a negligible amount of heat over a given time. It is more likely that the control circuits responsible for dimming the LED lights would generate more heat than the LED lights themselves.

 

[WannaGoMac]

Holding it wrong yet again?

See you're just holding it wrong!

 

[Triple22]

Would be a good idea if they had some thermal cover against and inside the back of the ipad. thermal pad would take most of the heat and probs wouldn't make it feel as hot but maybe warm(ish)

 

[burne]

Internal temp. Not external....

A few places on my body measure at 97ºF, like my armpits and behind my earlobes.

And my iPhone 4S gets up to 104ºF while charging and gaming at the same time.

I've ordered a bunch of these, to plaster all electronics, armpits and ears:

Better safe than liable.

 

[burne]

Well how much heat does an LED backlit display generate?

Well.. A quick google says 2.7W for the iPad 2 and 7W for the new iPad. Assuming extremely efficient LED's (10% overall luminous efficacy) that would yield 6.3W of direct heat. Two thirds of the 0.7W of light is converted to heat by the polarisers in the screen, and the liquid crystal will probably half that luminous flux once again. Leaving you with 0.15W of photonic emissions, and 6.85W of heat. The backlight-dimmer doesn't even has a heatsink, since its losses are extremely small.

You'll probably have a 7W energy saver lightbulb somewhere. Switch it on, wait 45 minutes and feel how warm is it. Be careful, don't burn your hands. A new iPad is cooler because it has much more area to dissipate heat.

Well, I would never chastise a consumer on how they spend their money. Remember this person already spent their money on a 3rd Generation iPad. I feel that canceling the order because of a fear of "another Transformer Prime experience" is a bit extreme. (fear based on a rare "yellow" screen or even it being a little warm when maxing the power usage)
