This is an update to my original post a week ago. I just returned my iPad3 to the local Apple Store, and purchased a used iPad2.
The iPad3 that I had was a 32gb wifi only (black). It was Fed-Ex'd as a pre-order and arrived on Mar-16.
Upon opening the box, I immediately plugged the iPad3 into my Macbook-Pro in order to sync with iTunes and restore from my iPad1's backup (which had been done that morning). Once the iPad3 was sync'd from the backup, I started configuring the "settings" app, mail app, calendar, contacts, etc. That's when I first noticed it was *very* warm. I figured it had to do with the charging so I left it to charge until it got to 100% (charge was initially 85% out of the box). About an hour later I unplugged it and left it to sit for a few hours while I tended to other work.
....Later that night I turned it on at 100% charge unplugged and cold, and brightness at 30%, and went into Safari to browse google-news and light static web pages; within 15 minutes I noticed the same heating problem, it was warm. Within 30 minutes it was *very* warm again. At that point I knew there was a problem since it was that warm and not even plugged in. Note, this is before I knew anyhing about the causes: bigger battery, larger processor, higher power consumption, etc. I couldn't believe the iPad was getting this hot, so I looked online and found other reports until finding this thread, which I've been following since last week.
I have tried all of the recommended troubleshoots here. Brightness at 100% definitely made the iPad hotter, pushing it out of the uncomfortably warm border and into the unacceptable *farily hot* category (for me). The one semi-solution that worked for me was to drain the iPad3 battery to 0%, and recharge it completely. I did this 3 TIMES, which literally took all day for each of the 3 sessions! (4 to 5 hours to power down with netflix - I played 1978 Superman1 over and over at 100% brightness, 5 hours to recharge). During each power-down session with netflix, I would feel the back of the iPad for warmth every 1 hour so. The first time it powered down it was HOT. The second time it was borderline hot, borderline very warm. The third time it was very warm. And that was the last recharge I gave it.
After that 3rd charge-down, the iPad was definitely not as hot as it had been. But running Safari, it was still very warm within 30 minutes. I may not have minded the heat so much personally, as I tended to only use my iPad1 for about 30 minutes at a time. But the fact that the heat is concentrated only in that left-corner, and it was giving me sweaty hands within 20 minutes of mild surfing in Safari, made me very uncomfortable with this purchase. I know a lot of people are defending the iPad3's heat-controversy making bloated statements such as:
--"If you want that much processing power and advanced graphics, of course it's going to cause that much heat".
--"The Macbook laptops get much hotter than the iPad3, you have nothing to complain about".
--"The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus 10 hours of battery life, all while operating well within our thermal specifications. If customers have any concerns they should contact AppleCare."
I contacted AppleCare 3 days ago, their response was..."duhhh...what heating issue?" My own take on these dismissals is this: the iPad is a hand-held device. Have you even used a mouse or keyboard that overheats? No, because people would balk at the idea and get one that doesn't overheat. You're not constantly touching the macbook with your hands, though it may fry your legs, you can always place something in between. But with the iPad3, if you place that over-heating sucker into a case, first you're trapping the heat inside the device, and who knows whether the engineers built the iPad3 to tolerate an environment where that-much-heat is not allowed to dissipate. And second, the case is eventually going to heat up to, and probably on that one lower-left side, which is annoying as heck. Who wants a mouse, keyboard, calculator, iPod, Gameboy, or any other hand-held electronic device that overheats in your hand after 15 mintes of light use? Apple has taken the PC approach of cramming in really revolutionary hi-tech into a form factor that is not ready for it. Only a PC-nut will geek out over the spec's and disqualify the usability (or heat output) of the device. That is not Apple's modus operandi, at least, it didn't seem to be when Jobs was running the place.
A couple other issues really pushed me over the edge in deciding to return it. FIRST was the statement of complete denial issued by Apple PR’s Trudy Muller in response to the verified reports of the iPad3's heat issue. SECOND was the long-long time it takes to charge the iPad3, 5 hours! (FYI - I was consistently getting 20% charge per hour). I was not at all expecting it to take almost all day to charge it. Sometimes when using my iPad1, I had needed to go somewhere with it when it was on a low charge. I could plug it and charge 20% within maybe 20 minutes, and that was fine. But with the iPad3, if I need a quick charge, I won't get it. THIRD was the slight increase in weight of the iPad3 and the fact that it doesn't fit iPad2 snap-cases. Again, here you see Apple compromising form/usability for function, ie, the engineers getting their way.
IMHO, the "new" iPad is really the "iPad3 Beta". As a long-time Apple-user, I have seen a consistent trend where the first generation of their products has been messy and had something screwed up about it. My first iMac had a faulty power supply. My first Macbook Air had a faulty display. My first Macbook had a faulty keyboard. I chuckle when I think of these issues. But in each one, Apple gingerly took care of the issue. I am confident that the REAL iPad3 next year will be A) more power efficient, thus requiring a smaller battery which means B) it will be smaller and lighter, maybe the same shape as the iPad2 and even lighter, and C) quicker to charge and D) much less hot to handle, maybe being as "normal" as the iPad2. I admit, I was so satisfied with the original iPad, and envious of the iPad2 owners, that I imagined to myself that Apple maybe had gotten over their first-edition jitters. Fortunately, the iPad2 is everything the iPad1 was but better and without any visible drawbacks. I ended up getting a used one this week and am quite happy using it for at least the next year while Apple works the bugs out of its iPad3. The iPad3 is Apple's flagship product, I'm very saddened to see the slippup in its usability.
iPad3 vs iPad2 - The iPad3 display, OMG truly, it makes every other screen look grainy and blurry by comparison. Unfortunately it was like opening Pandora's box, because my laptop display and external monitors now look blurry and old. Major sadness here. And the iPad2 display, I never saw a problem with it or the iPad1 display, but now they also look blurry and old, and I wonder to myself how I put up with such a blur for such a long time?? (Much like wondering how we put up with CRT Displays for so long before flat-panels and LED displays). Plus the iPad3 has voice dictation which worked really well for me. However, the iPad3 is NOT FASTER than the iPad2. In my side-by-side comparisons, they were the same speed for: App-Launching (Zite, Mail, Safari, etc), Safari Web Browsing, return-to-Home Screen, App-Switching-Swipe-Gestures, etc. EXACTLY the same speed. I understand that the iPad3 has 2x the memory as the iPad2, but I think that higher-memory only comes into use when you're playing the new hi-res action games like Real Racing 2. The iPad3 and the iPad2 last ABOUT the same time. Ie, they both drain the battery at 10% per hour on light web surfing at 30% brightness. Now here are the iPad 2's advantages: it's lighter in weight (I easily feel the difference and can appreciate anything that's lighter). iPad2 can charge it's battery in about 2 hours, compared to the 5 hours that the iPad3 took to charge. Used iPad2's are going for about half the price, so you save a couple hundred bucks which you can use to purchase the REAL iPad3 next year (I even got the year-old apple-smart-cover along with the used iPad2). And, I know this is petty but it's a real concern, the iPad2 doesn't make all your other computer displays look like crap. Heck, the iPad3 makes paper books look like crap. I just don't want to deal with that right now. iPhone hi-res I can appreciate because it's such a small screen, the hi-res is very useful. But I don't need hi-res on the iPad, or on my computer displays, and I don't appreciate that the iPad3 made everything else I own look so blurry. heh.
Just one final interesting note - when I returned my iPad3 to the Apple store I was met with disdain upon stating I had the return. I walked in, found one apple-guy, told him I had the iPad3 to return, and he told me he couldn't do returns, that I would have to find one of the sales people. I asked him how can I tell who is a sales-person, and he said I should just walk up to people and ask around. Really? Okay, so I did. It took 4 apple-guys, an apple-girl, and one more apple-guy before I found someone who would process the return. The guy literally openned the box, scanned it, and started walking away without saying more than "what's your email?" and "it should take 2 weeks to get the refund". I had to call out to him as he was walking away to ask him if I could get a receipt, you know, so that I don't let him walk away with $750 of equipment (iPad 32gb plus leather cover). He gave me this look and said it would be emailed, but I insisted on having a print-out, so he obliged without another word spoken. I only mention this last little bit in contrast to the excitement, cheers, and high-fives people get when they were buying the iPad3. Returns definitely show you the bi-polar side of Apple Customer service. I shudder to think the reaction if I had tried to exchange the unit after that 14-day-return-window had expired, I'm almost certain people are going to be told that their overheating iPad3's are "operating well within our thermal specifications".
As of now I'm ending my subscription to this thread. I hope NOT to you all in the forums next year when I get the iPad 4.
Goodluck All!
