Infrared test shows new iPad running 10 degrees hotter than iPad 2 - Page 2

Please don't embaress me, just kidding. The iPad does get very warm ok hot even after playing a game like Modern Combat 3 for more then 40 mins. I noticed this last Sunday but that was the only time. Everyday use not so much, I think just when your pushing it, then it gets a little uncomfortable.

I was playing around with a 4G LTE model at the local Apple Store and those iPads are turned on and plugged in and already running as hot as they can. I played one of those high resolution games and there was a section that ran hotter than the rest, but as i played the game, it didn't generate any amount of heat that I thought was unbearable at all. It was just a little warmer. Not a big deal.

I wonder if the so-called problem is worse on a 64 GB version due to the increased amount of memory. Other than that, i don't see any problem with these new systems.

I've noticed it runs hot in the lower left corner, especially when plugged in. I'm assuming Apple is 100% aware and signed-off as a trade-off to the beautiful screen. It is definitely a compromise. I've love the fact my iPad 2 runs so cool

The next rev should take care of the heat as they dramatically shrink the internal components (LTE chipset, A5X, core memory, RAM, efficiencies in the display). The internal efficiency gains should be dramatic

Now I understand better why Apple did not increase the CPU clock speed or go 4-core. They did everything possible to get the screen out the door

(Late edit...my rant isn't directed at the author of the previous post...I actually agree that Fahrenheit is quaint. But...)

You use Celsius? Let me worship you like the temperature-knowing god that you are. I've met many..."non-Americans" who inexplicably take pride in the fact that they use Celsius. I understand that the entire world using the metric system is ideal for education and science, but...

...please tell me...for those of us who are not scientists (you know, ninety-nine percent of the world), what does 0 tell you that 32 doesn't tell me? I've met Brits who quite literally look at their stupid smartphone to gauge temperature, and then suddenly wax intelligentsia about how superior Celsius is and how stupid Americans are for using Fahrenheit...as though using Celsius told them anything more than using Fahrenheit told me, and as though they had any choice in the matter what was taught to them when they grew up. Seriously, they look at their phones and feel smug about the fact that it says 25 instead of 77. ...No, you're right, this Obviously confers an enormous advantage and if I wasn't such a fat, stupid, lazy, litigious American, I'd have figured that out. If my phone had said 25 C, I'd have known to pick the white t-shirt and not the blue one.

Being pompous over something as ridiculous as a fixed scale is a sign of a lack of intelligence, not the opposite. When I begin my work as a climatologist or chemist I'll promptly convert to Celsius. Should take all of a few hours to adjust.

I don't think there's any doubt that this will become an issue. Some people are always looking for something to bitch about and will latch onto this. Just look at some of the snarky comments in this very thread. Soon we'll have the Apple discussion forums thread "views" counters proclaiming this a major issue. Then comes the "in depth" investigations by c|net for example, and of course the obligatory class action lawsuit filed by somebody claiming their iPad "burned" them.

So yes, "heat-gate" is coming and you can take that to the bank.

You are right, metric is better for science but imperial is better for everyday life. What you want out of your measurement system, is to help you grasp a quantity is without having to see it. Relating that quantity to solid objects like a certain number of feet or stones does the job better than relating it to imaginary things like meters.

10° is a big difference especially that it get so close to the upper limit of the parameter set by Apple. I fear playing graphics intensive games or even movie watching will cause the iPad to overheat and shut itself down.

Note how it was determined - they ran GL Benchmark - which puts the GPUs to the maximum test. They are stressing the heck out of all four GPUs, so the heat generation is undoubtedly greater than the normal user would see. If you are doing something that stresses the GPU (action games, perhaps), then you might see it getting warm.


Since LTE uses more energy than WiFi (as shown by shortened battery life), then using LTE would cause it to get warmer. However, the effect is probably considerably smaller than stressing the GPU cores.

This same issue was reported with the iPad 1. It was a non-issue.

Likely it depends on various factors, like what the iPad is doing at the time. This test may have been at "idle".

Body temperature is 37°C, so the iPad is cooler than you are.

It's the display's pixel/backlight driver circuitry making most of the heat. The circuitry is usually located at one edge of the panel that has the connectors, which in this case, the left side of the iPad.

Turn down the brightness setting (like under 70%) and there will be no heat.

So it runs hotter and is heavier.

How is this a step forward?

Water freezing is an easier concept for a Canadian to understand than boiling water is

I had no idea that the new A5X was so much better in GPU performance compared to the Tegra 3.

Thanks.

I wonder how it fares in pure number crunching, like for use in a gigantic spreadsheet?

You guys are talking nonsense. As a Brit, it's painfully (at times) obvious to me that we feel comfortable with whatever random units people are using when we grow up, it's not at all about what "feels right" or whatever, just learnt behaviour from your environment. Be glad you're not living in half-metric land. We Britons are truly fucked

For example, I:

Have no concept of what a "pound" is other than £, for body weight is in Stone. Scales are all in Stone, so I weigh, for example, 13 1/4 Stone. What this means in pounds/ounces/kg I seriously have no idea off the top of my head.
Measure all cooking in grams, no idea about ounces/pounds really except a pound is about half a kilo (eg. in beef) like a pint is half a litre (568ml is remembered due to beer). Though mainly use ml in cooking, want my pint of milk or beer.
Measure distance in meters, then miles \ - Know that a yard is 90cm roughly, never use it though and find it confusing that road signs tell me how many yards something will be in, just because we use miles & mph.
Know my height to be 5'11" (is that written right?) and 180cm, but generally measure stuff in cm, feet and meters. 4 inches of snow. 2 feet of water. 2cm bezel. 9mm thin.
Couldn't tell Fahrenheit 451 from, well, anything. Summer newspapers confuse.

It makes sense, it just doesn't make sense. Be glad you're all imperial. Or, frenchies, be glad for your metricyness. We'll be using the British Standard of grams, kilos, pounds, stone, meters, feet, miles, inches, centimetres, millimetres, yards, centigrade and Fahrenheit

Why not? All those people who get erections over the number of cores or how much memory their hardware has have to pay the price sometime, might as well blame Apple

I find it kind of offensive that the story is from Belgium, and yet every tech blog in the world is taking the time to translate the story into fahrenheit when in fact no one in the entire world even uses fahrenheit except the USA and celcius has been the standard for thirty to forty years.

Most people alive today have never used fahrenheit or even know how to convert to it.

It's 5.3 degrees warmer, not 10.

Edit: I didn't realise that people were already arguing about this.
Apologies for fanning the flames, but this article started it by reporting the whole thing in fahrenheit.

IMO this is the only sensible post on the whole thread and the only one worth reading (outside of the fascinating fahrenheit/celsius controversy.)

...please tell me...for those of us who are not scientists (you know, ninety-nine percent of the world), what does 0 tell you that 32 doesn't tell me?

It tells me that water become ice, while the 100 tells me that water become air, you know, that water is funny it also tell me that 1 cubic decimeter of water (10cm*10cm*10 cm) equal weight of 1 kg. Since we live on the planet 90% made of water this make sense to me.

Are these tech blogs based in the USA? ("every tech blog in the world")

No mystery at all. It is entirely correct for an "author" to use the local unit of measurement. AppleInsider = American website. Notice that there is no second level domain after appleinsider.com (e.g. appleinsider.com.au).

edit: Just for clarification: I truly believe the metric system is far more efficient, but confusing the reader (in this case many Americans) isn't.

He was being funny, nothing that required the above babble, that being said metric rules.

[QUOTE=dragan0405;2076854]
That is like asking what iOS will do that Android does not do.

IOW, it is beside the point. The point is NOT that one system packs extra information. The point is that one system makes more sense, all things considered.

1) That's not true. More then US use Fahrenheit's scale. Not many more, but not just the US.

2) Fahrenheit's measure was standard long before the metrification of Europe.

3) There are other measures, too. One of my favourites is Kelvin but it has no use in every day life because it doesn't make sense to refer to the average temperature swing as being from about 260° to 305°.


PS: On the other thread we're discussing measuring visual acuity with a 20/20 scale.

The Apple spec is for ambient operating temperature, and the temperature being reported in this article is the case surface temperature. Apples and Oranges. Keep the ambient below 35°C/95°F and you will be fine. I'm sure Apple generates their spec values based on use cases that include graphics intensive games.

There are more factors than ambient temp. If you use the iPad outside on a beautiful 83 degree day, it might well overheat in the sun, but not so fast in the shade.

Sure, though I'm guessing Apple considers this as a use case, as well. My point was that the temperature in the Apple spec is not the same as the temperature presented in the article, and the perceived lack of margin isn't as bad as it seems.

The iPad gave my friend 3rd degree burns on his fingers and the back of the iPad is hot enough to fry eggs....Mike Daisey giving you the total truth with a smidgen of hyperbole and bombast.

Excuse me- but Siri would beg to differ.

Not to mention the new iPad is so hot it's responsible for Jason Russel's "meltdown",caused him to strip naked and maturbate in public.

I guess Celsius 233 could have worked, too.

good grief most people barely notice that it's a bit heavier. I'd say the trade-off between the very slight increase in weight and the retina display is absolutely worth it.

I love how pondosinatra doesn't acknowledge any other change to the device or how the iPhone has also increased thickness and weight, and possibly heat output, despite getting further and further ahead in the smartphone market.

It's an imaginary scandal. Mine run cool all day.

I love how you think I somehow should feel compelled to do so...

"That new vehicle you sold me gives me 3rd degree burns"

"Yes, but it comes with XM Radio....."



In any event, I'll probably end up grabbing an iPad 2 for cheap.....

I had exactly the same experience when I sat down to read a magazine in Zinio on the new iPad. After a half-hour I noticed it was getting pretty warm on one half, so I rotated it around and held onto the other half after that. I checked later and the first half was still warmer, so it wasn't just my hand heating the case.

I imagine that depending on the situation, this could be cosy, unnoticed or annoying. In every situation where I've used the iPad since then, I haven't noticed it.

Let's examine the hyperbole.

What does it take to get a 3rd degree burn?

• 100° F — N/A
• 113° F — 5 hours
• 116.6° F — 5 minutes
• 118.4° F — 20 minutes
• 120° F — 10 minutes
• 124° F — 4.2 minutes
• 131° F — 30 seconds
• 140° F — 5 seconds

A colouring book runs cooler and is lighter than an iPad 2 so you are better off with that.

Well that's just silly. I can't accomplish your tagline of being able to play games while taking a dump with a colouring book...

Typical, again statement by people who have not clue what they are saying

Apples temp spec of 0 to 35C is the air ambient that the device is rate to operate normal in, in this case the ipad will operate in a 95F day if it is 100F out you better turn it offer. Also, there is another spec which is the surface temp can not be above 50C to the touch to avoid any sort of burning of the skin.

Yes, I was told that. What we Americans would think is funny though was that it was a barker at a carnival devoted to some guy who tried to kill the English government. That's not usually celebrated here.

...although, listening to many older (mature) people here, it might be celebrated if it happened here also! :o)

And they say it weird. I'm 8 Stone 2. They still put the Lbs. in at the end. I thought it was pretty cool though!

Sorry to hijack the thread. It's from yesterday, so I didn't think it would matter much...
