According to Apple, the iPads' battery temperature treshold is 32° to 95° F. That’s 0° to 35° C.

False.

That's the environmental temperature, not the the hardware temperature. I'm puzzled at how often this falsehood is repeated.

In the case of iDevices, environmental temperature=operating temperature because of a known fact that in Apple designs, they've stripped out the plastic made protective shield of the battery, thus decreasing the battery's heat resistance.

More speculative nonsense.

The integrated design does eliminate some internal battery packaging, but heat propgates to the battery in any design.

That's a stupid comment. Go look at IHS iSuppli teardowns. The battery itself is a rubbery lithium ion because the plastic shield is removed. The rubbery stuff is right undert the plastic section. If you'd know a thing at least. Integrated design is a pure speculation. You can never have such a slim device with the plastic shield. That's what's preventing other manufacturers from getting slimmer devices. By boldly cutting out that plastic, Apple achieves a slimmer design.

To add on, Li-ion batteries are already heat sensitive items. What kind of crap would turn a Li-ion more heat resistant?

Kim's right and you're wrong. It's as simple as that. There is nothing in his posts to suggest that he is working for a competitor. That's complete speculation on your part and your arguments to that effect don't make any sense. What is keeping this thread alive is misinformation, pure obstinency or just plain trolling.

Learn how the forum works and what member points mean. Members with points and longevity on the forum have credibility. You really don't have any credibility or appear to know what you are talking about. "Robot responses" and "call centers in India"? Yeah that makes a lot of sense. Just nonsense as is a lot of this thread.

I'd advise anyone who is having a real problem with their iPad to ignore this stupid thread. It's simply full of nonsense and misinformation. Posting here is a waste of time; you won't get any help here and Apple isn't monitoring these forums for bug reports. The forum is not a complaint department. There is a specfic channel to give feedback to Apple http://www.apple.com/feedback/ipad.html If you feel that you have a heat problem with your iPad you should contact Apple Support or visit an Apple for help and resolution.

Well I'm no fanboy but would like to share some thoughts.

1. Not everyone has the "hot" problem nor the "long charging" problem. We sat up last night watching Netflix for 20 minutes and the pad was cool to the touch. It recharged from 30% to 100% today in less than 4 hours.
2. Heat indicates something drawing power. Long charging could also indicate something drawing power.
3. If there happened to be an app or service that was tied up in knots it would a) cause the iPad to get hot and b) take longer to charge.
4. Something VERY similar happened with the iPhone 3GS with MS Exchange running on it. The suggestion at the time was to delete the MS Exchange email account and completely reset the phone, starting over (worked for me).
5. The new charger looks EXACTLY like the iPhone 3GS charger EXCEPT the new one is rated for 5.1V and 2.1 amps vs 5.0V and 1.0 amps for the old one. (Ahem...label and ONLY use the new charger lest you run the risk of overheating the old charger...fire hazard). Using an iPhone 3GS charger would ALSO take much longer.

So, I would suggest before running willie nillie to the local Genius for a replacement perhaps removing all apps and email accounts and completely resetting the iPad might solve both problems. Maybe...I have no proof...just a thought.

An informal summary of the potential issues we are seeing:

• Based on the reports of many people reporting no heating issues, it seems that there is a small subset of iPads that legitimately have real heating issues. These are the ones that get very hot, potentially with the warning cool-down screen. These are different from the general "my iPad is warm" complaints.
• The iPad 3 does run warmer than the previous iPad 2 - serveral sites have reported a difference of about 10 degrees F. This is what Apple talks about as "normal" and "within spec". The reason, from what I've read from you guys and elsewhere, is primarly the increased backlight power, then followed by the more powerful A5X chip. This is where decreasing the screen brightness helps reduce heat, and why warmth is felt in the lower left side of the iPad where the A5X chip is located. The iPad 3 is more powerful, so essentially you have to choose between a cooler operation or a more brightly lit screen. Apple won't be able to magically "fix" this problem, because it's not a problem, it's just a change from the previous model.
• iPad 3's seem to have day-zero issues that get better over time. The most obvious is if you restore from iCloud, which then taxes the iPad for a while as it re-downloads everything. That seems normal. Otherwise, people have reported success with letting the battery drain completely or disabling location services. It's possible that iOS 5.1 is too aggressive with location services, which could be tweaked with software updates. The other natural factor in play here, IMO, is that over time you get used to the increased warmth of the new iPad.
• For the charger getting hot - That is normal. Every Apple charger I've used gets very hot, but I've never had a real problem with that since you don't really need to touch the charger ever.
• People who claim that they experience no increased heat issues either A) Have not used the iPad 2 before or for a long time, and don't remember how it operated, B) Are more tolerant of and/or don't notice the measured increased warmth of the new iPad, C) Naturally run the iPad at a lower screen brightness, and/or D) Need to justify their expense by downplaying issues.

Therefore, here's what I'm thinking:

The new iPad will get hot during intensive tasks - this is just a tradeoff between a better display and better cooling. It's inside spec and it won't kill you, but it can be uncomfortable if you come from the more cooler-running iPad 2. The new iPad will get warm during simple tasks such as browsing if you want 100% brightness. A few iPads will be hot regardless - these should be returned as they're lemons.

deAn iPad runs an ARM Cortex which is not built to use a fan, it is an energy efficient and completely different architecture from what Intel manufactures. Currently on my 2nd new iPad after the first exchange, its still having the same issue, just as uncomfortably hot while on apps running Retina graphics, still the over 50 celcius issue. But of course, this reduces the usability of the iPad as it sweats your palms probably.

So comparing an iPad to a laptop wouldn't be a fair comparison as they're different beasts. Tablet to tablet, or iPad to iPad. It works as simple as this.. just like an Gala Apple vs. Fuji Apple rather than drawing a comparison out of a banana an and Apple. Doesn't make sense to me in the context of comparing iPads to other devices.

Heat is definitely an issue because what Apple always does in its design in iOS devices is removing the protective shield from its Li-ion batteries to save space and cut thickness of its devices and this causes lower heat resistance for its batteries. This in turn is a huge issue when heating comes into play. The main cap to the OTP right here on the iPad is the battery.

Environmental Requirements

• Operating temperature: 32° to 95° F (0° to 35° C)
• Nonoperating temperature: -4° to 113° F (-20° to 45° C)
• Relative humidity: 5% to 95% noncondensing
• Maximum operating altitude: 10,000 feet (3000 m)

Since the heat is definitely over what its weakest link, the battery succumbs to heat, battery will drain at a much faster rate as the iPad can easily exceed 35 celcius. I'm talking about 1/3 brightness here on Real Racing 2, that's how bad it is and its causing the supposedly strong battery to discharge quicker. This is going to create a lot of service calls even though some people do not care about this at the moment. The battery is sure to fail quicker in dismal operating temperatures...

That's what I'm experiencing also on my 2nd new iPad, it was barely 6 hours of battery life on a Wi-Fi iPad...

So to those who are saying its fine, you can take the heat - sure, your new iPad's battery probably will need a defibrillator on constantly on the first year. After the first year, the hospital (Applecare) is going to put your iPad to sleep because it wouldn't even last beyond the 2nd year probably.

ChangeWave: "Apple's new tablet scored even higher than the [iPad 2]. Heat-gate was a nonissue."

• 98% were either satisfied (16%) or very satisfied (89%) with [iPad 3]
• What they liked best "by a landslide" (75%) was the high-res display
• 89% said the much-publicized heat issue was either not a problem or
  something they had never experienced

"…No other tablet is getting stratospheric satisfaction ratings like this, not even the iPad 2. Only 74% of iPad 2 owners surveyed last year pronounced themselves "very satisfied."

"And based on a side-by-side comparison of "Heatgate" and "Antennagate," ChangeWave concluded that the operating temperature of the new iPad was a non-issue for most users: "Simply put, the heat issue does not appear to be a perceived problem for the overwhelming majority of new iPad owners."

What is the issue here? The unit gets warm when it runs hard and heavy for a while, so what? Touch the bottom of many laptops or desktops and they will get hot as well. Is this shocking?

The unit is pushing a massive amount of battery power to sustain the screen, that means the battery will get warm, just shocking... 😮

I'm going to reiterate on the 50 celcius point. I don't live in a climate country. Regular RTP is always above 20 celcius.

Interestingly, the "New" iPads produced in 16GB capacity after the New iPad announcements are using a second gen A5 processor, a migration from 45NM technology to Samsung's New 32NM HKMG.

Why does NM matter to consumers liek you and me? This technical improvement simply equates to the ability to put the same number of transistors in a smaller amount of space. This also means the design is more power efficient and space saving or even capable of achieving LOWER operating temperatures at the same time in simple words. To the contrary, New iPads' A5X is running on the 45NM technology which is less efficient.

After poking around, the comments that strikes me the most is that Apple is testing the water by first putting this on iPad 2s and Apple TVs with hope of bringing them to newer chips like the A5X or even A6 in the future for efficiency but then again they're not ready to make the change.

To me, this is an indication that Apple recognises the inefficiency of the A5X or current processors they hold but going on with the current A5X's current 45NM could also indicate:

1. Means of Apple attempting to manage expectations.
2. Doing this to the A5 is also a sound approach IMO because people and even they themselves know the device as a whole achieves a gold standard in terms of heat management which makes it even sounder for releasing this like in a "public beta" fashion
3. The spotlight is now shifted to the new mainstream device, the New iPad which makes the change of an innard of the iPad 2 less apparent.

Leaving it up to this point.

Wrong.

By Chinese standards, Foxconn workers are well paid — which is probably why people gather by the thousands to apply for Foxconn jobs.

Mike Daisey — is that you?

Haven't you read? It was reported on several reputable newswires like Bloomberg, Reuters etc. The Foxconn auditors have audited the firm. So, the auditors were wrong. Is that what you meant?

1. The workers are truly overworked.
2. They're asked to hire more if they wanted to keep production volumes.
3. Hiring more separate workers already equates to higher labour costs rather than using the same number of workers.

I responded to Bellatone's caps-lock bloviations. His "slave wages" claims are demonstrably false.

Also at work we have a few new iPads for app development and they work just the same...

You should stop throwing comments like this around. Read around the net, how many complaints, how many theories with correlating variables. Like someone said earlier on another thread, this isn't about picking on Apple, it isn't Obsessive Compulsive Disorder or anything like that.

Contract manufacturers train their workers through a tutorial-like session and there are possibilities of manufacturing instructions that are incorrect (i.e. application volume of compounds like thermal paste) etc and there's more than one facility out there in Foxconn and iPads are manually assembled to an extent.

Some iPads have hair/dirt IN their screens (pictures), some have cracks, some with a broken display, heat, poor internet connectivity of 4G iPads etc.. Not throwing in assumptions on number of cases, so please don't either. I suggest that you read around before throwing insensitive remarks.

The point about coming to these forums are that you seek help from Self-help Gurus in these forums. The general intent of visiting these forums are either that

• You have a problem, you need technical advice
• You've received help and now you're offering free advice
• Generally, people with working devices won't even bother visiting these forums, I hope that's clear to you.
• I suggest that before you say 'trolling', understand the demographics of these forums. They're also not as childlish as regular game forums.

There's also corrlelation between build quality & assembly plant used in case you don't know. I'm one who had 3 New iPads due to exchanges and not the only one with such a final conclusion.

I never said bank account # with pin. Never said "your" social security number. The serial is, and I stand by this, IS like a social security number for the iPad, NOT for the OWNER of the iPad. It's an identifier to the iPad as a social is an identifier for a person.

I know. I meant that too. It's an identifier for the device. So is there anything sensitive (like links to your social security no. etc) anyone can get out of a device if the serial number is found? This is what I meant on that point made.

By the way, even without the lookup, you can still tell which factory assembled your iPad.

The first 2 letters (Factory code) are concatenated with the other identities in the string of 12 characters.

Surely, you can count the number of Foxconn facilities with just a pair of hands, under 10 different character combinations for the first 2 char.. The first 2 letters are NOTHING but factory code.. if you're not going to tell anyone about that, which is usually either

• Factory: DM (China - Foxconn)
• Factory: DL (China - Foxconn)
• Factory: DN (China, Chengdu - Foxconn)
• Factory: DX China
• Factory: DQ China
• Factory: DY (China, Shenzhen - Foxconn)

there's nothing much people can help right in this forum.

Sorry, but Kim Hill1 is correct on all counts:

1. 95° is the maximum mbient temperature that the iPad is designed to operate in. It has nothing to do with the operating temperature of any iPad components.

2. Environmental (ambient) temperature has nothing to do with the operating temperature of the iPad.

3. 34.6° C is certainly well within the normal operating temperature of the iPad. Anyone who told you otherwise either didn't know what they were talking about or you misunderstood them.

1. You're saying you never got an iPad with heating issues.
2. You're trying to say you know when does the variable drain rate kick in. As compared to someone who held 3 New iPads and has the ability to tell when does that increased drain kick in.
3. You're the scenario as though everything in the iPad is living in exclusion from the battery and truncating the justification by omitting other posts containing relevant factors.

If you never seen when does the battery literally sweat, then you won't know the temperatures you should look out for.

Are you even helping out people in this thread? How many have you helped?

p.s. I won't even get personal with Kim who already has enough embarrasment in the low 60s pages.

You can help by telling people which factory was your iPad manufactured.

The string of concatenated 12 characters contains your iPad's factory code. From that, you'll be able to tell which factory assembled your iPad (with the factory code).

The portion you need would be the first 2 letters of your serial.

They usually include:

• DM
• DL
• DY
• etc..

With every posted reply you seem to reinforce what YOU stated..."we must be a large(millions strong) group of complacent idiots". I am not attacking Apple, yet you immediately defend Apple with lengthy propaganda posts, but I AM shining the light on those such as yourself that get overly defensive and take any criticism on Apple personally. You are the ones making Apple a cultish religion and are prepared to go to Holy War over any valid critique. All I was saying is that YOU are the problem and you're NOT helping Apple, even though you may think you are...you actually hurting them, like Tom Cruise hurts Scientology. Those who are IN the cult NEVER see it for what it is or see their behaviors or responses for what they are, you'd need to be able to let you fanaticism wane long enough to step out of the cult, get deprogrammed, and you might be able to see what I am talking about. Unfortunately, like Scientology victims, or Fundamentalist Religion/Cult members it is very difficult to get them to see the freedom that exists with choice and questioning authority (Apple in this case).

Prophloe, you yourself stated in a previous post that your own Son told you that the iPad 3 was too HOT for him to hold. You also tout him as an Apple Genius, yet suggest him a fool for thinking the new iPad is too hot, you're selling your own family short in defense of Apple (a classic cult member move, and also why Tom Cruise is getting a divorce right now). STOP THE INSANITY, your own Son wasn't using the iPad in the sun, or on a stove as you stated, yet he felt it was uncomfortably HOT. How could a child that young make that observation about it being too hot, well he was just being HONEST. He's not old enough to be brainwashed to the point that everything he says or thinks needs to be filtered through his Apple brain first. Given time I am sure you'll take care of that, but I hope he can become a free thinker instead.

My user name is tounge-in-cheek, I actually own a lot of Apple products and since I own them and live with them everyday I also live with their short-comings. I certainly won't ignore their short-comings or turn them around in a twisted mind and call the short-comings "features" as Apple does. My advice would be that the world is a much richer place if you just open your mind to possibilities. The possibility that one of Apple's factories in China is churning out some HOT iPads. The possibility that that no matter what the problem with it there won't ever be an official recall on a disposable device like an iPad, instead Applle just takes them all back as a returned iPads (THAT'S STILL A RECALL, just quiet and unofficial!!!!!). The possibility that you have and continue to go too far with your blind defense of Apple and that it is unhealthy. The possiblitiy that some of you are highly paranoid in assuming people have multiple aliases in a ploy to maliciously drive up the complaints about HOT iPads. The possibility that Apple isn't perfect or God-like. Again, I am NOT attacking Apple in my posts, neither is someone who posts here angry about a problem with an Apple product. I own many Apple products, I am happy they are succeeding as a company, but I do have a low tolerance for the lies and propaganda (Apple may call it marketing, it's magical) and the immediate wall of defense that goes up at the first critique of an Apple product. I can tell you didn't even read any of my posts clearly, unfiltered, or else you'd see that. Acknowledging your short-comings is healthy, it helps you to grow, you all need to see how this could benefit Apple and as an extension yourselves.

Spoken like a true cult member. "There's no blind cult or religious Apple fans in my family. We just like Apple because they've made many great products which we own and use daily for many years."...if this were true you wouldn't be getting personally offended by critical posts directed toward the iPad as a product...that's all it is, a product.

FYI, another typical cult move is to turn a criticism around on someone, I never said anything about there being a conspiracy, the Apple cult is right out there in the open. I dont believe in conspiracy theories, as i dont think our species is bright enough to be able to pull them off successfully. You, iKrupp, and Kim Hill to name a few are all stating that there must be a conspiracy on this thread to make the complaints seem higher in number than they are. Which says a lot about how desperate you guys/girls are, and for no good reason really since Apple is just another tech company...they don't need your desperate defense.

Or calling my post irrelevant when all you post is about how of course people will think their iPad runs hot if they use it on the beach, in the "blazing sun", over a stove??? ( a bit of insanity creeping out here), or near the mouth of an active volcano. How much more irrelevant can you get? Your comparison of the iPad to a boom box and beach chair were real zingers.

If you acknowledge that there are Apple Lemons, then WE ARE IN AGREEMENT and you can stop lambasting people who post here with a problem with iPad heat. You can't change their minds, like YOU say it is their opinion...so they have a right to it and they aren't wrong if the iPad is too HOT for them. You also have to realize that not everyone who notices the problem is going to post here, also if they are new to iPad they won't know older iPads run cooler, not to mention those who are willing to live with the problem because they are fans or because they just paid a premium price for this thing, and Apple is never going to publish the number of returns. So it is difficult to know how widespread the problem is. You can still say there is no problem, but that's what was said about the antenna on the iPhone4 (I own a 3GS still and am happy). I think it is up to the consumer to decide what right or wrong with a product, people have a right to their opinions in America.

p.s. I am happy for you that you didn't get a lemon, I enjoy my iPad2 for not running hot. So we can agree that no matter how much engineering goes into Apple products they are still made in China and there are quality control issues just like every other manufacturer, and it is OK no sense crying over it.

1. This is an 83-page thread — but you've achieved a one-day record for the longest, screedy rambling in the whole thing. And then you have the colossal nerve to flame others for "fanaticism."
2. The idea that you'd dismiss the obvious trolling and sock-puppetry is absurd.
3. I've also written Apple-critical posts & started Apple-critical threads. I suspect you haven't seen them, due to the extreme altitude of the high horse you've set yourself on.
4. You really have no sense of irony at all, do you?
