Photo: iPad Temperature Warning Dialog

I actually wish my my thinkpad would display a dialog when it was overheating, instead of just completely shutting down randomly in the middle of my work. Come to think of that, my Dell did that too...

(and this is coming from someone who hates iPads)

Well, it's a tradeoff. As long as your ThinkPad has sensors (which it probably does) you could set it up to warn you at a certain temperature. The trade-off being that if it actually overheats you can get various random and undefined behavior from the hardware, so you have to set it somewhere below that threshold (which means finding that threshold and setting the warning level some distance from it).

My iPad has been running for the last 5 hours. Some videos for my boy, some khan academy for me, syncing books from amazon, loading PDFs for school, browsing the web. My battery is down to 68%. It was at 85% when I pulled it out of the box this morning. Mine is only barely warm to the touch on the back. I wonder what caused the heat warning, a defective unit or something else?

     loading PDFs for school

What app do you use? iBooks?

Personally I use Google Docs for PDF files.

I'm trying out iAnnotate right now. So far it has worked pretty well. I tried loading one into pages and it didn't recognize it. I'll see if iBooks can do it as well.

*edit: it doesn't look like you can load PDF files into iBooks

Thanks. I'm waiting for my 3G iPad and want to use it to annotate pdfs

>>>I wonder what caused the heat warning, a defective unit or something else?

He had it outside in the sun. Must have been some sunlight!

The same dialog is on the iPhone also.

EDIT: http://support.apple.com/kb/HT2101

This is what happens when I don't have an iPhone. I knew that moisture could be a problem. I'd never heard of heat before.

My iPhone has never flashed this message. I have never seen an iPhone or heard of an iPhone flashing this message. It exists in case an iPhone gets over heated, say if you were wandering around in the Mojave. The existence of the message is far preferable to the possibility of a melted iPad/iPhone if you took a field trip to a foundry.

I'd call Apple products "hot-house orchids" except that orchids like it hot and humid. I once had to return a Nano that had water damage-- except that I hadn't gotten it wet. The support bob on the phone said it could be water damaged by keeping it in a pocket while working out. Isn't that a common use case for an iPod Nano?

No, you're supposed to mount it to your arm so that everyone can see how awesome you are for owning an iPod. Apple doesn't get any free advertising when it's in your pocket!

Have you jogged with headphones on and the player in your pocket?

How much heat is it generating turning the entire LCD matrix on at once?

LCDs do not work that way http://www.youtube.com/watch?v=ZQg8JKo_3ZQ

It takes a tiny amount of power to run the switches in the LCD panel. Almost all the power is used by the backlight that illuminates the whole thing. The iPad uses an LED backlight that uses less power and is brighter / pleasanter than a traditional fluorescent backlight.

I wouldn't be surprised if it turned the brightness all the way down when showing this screen, but there isn't anything else it could do to save power on the display and still show something to the user.

The explanation on the Apple website for the iPhone(/touch) says that screen brightness might drop, signal might drop etc before it goes to this screen.

Apparently Apple thought well ahead that it might be best if their device regulates its temperature rather than overheat and shut off. I'm actually exceptionally surprised by this, kudos apple.

Anyone else feeling this the beginning for a wave of iPad complaints?

I don't see how it's a complaint. It's informative. Who expected that?

Oh, please.

From your submission history I see that you like Apple... but not seeing that this could be seen as a negative thing is a bit over the top, don't you think?

A iPad which is constantly too hot could be seen as a negative thing. The existence of temperature sensors inside the device and the existence of a warning dialog? Uhm, hardly, I guess?

I have seen this warning once in almost three years of iPhone use, after the phone had been in a hot car. I don't think we can assume that the iPad is faulty simply from the existence of this message.

Agreed, you don't post a screen like this unless you are pretty pissed off that your $500 new toy just stopped working for a while out of the blue. Strange how almost all negative iPad remarks are getting down voted.

Seems you're going strong, though! Hang in there! :)

Yes, I like Apple, but not without valid complaints (I've done posts blasting them for book banning and recently for ignoring book metadata). But I still don't see how this can be interpreted as a complaint.

Look, I really hate to go into some meta-crap here, but really, you are just looking silly now. You yourself even said in this very thread:

I knew that moisture could be a problem. I'd never heard of heat before.

I'm sure you'll now come up with some way of saying that a problem does not constitute a complaint, that moisture is a problem but heat isn't or that it's only a problem on the iPhone, not the iPad ...

I wasn't even saying that it was a problem in the first place, I was jumping at your comment that it could not possibly be seen as a negative thing.

Full disclosure: I have pre-ordered one (Europe).

The release date of anything always coincides with the beginning of the complaints.

We've been seeing complaints for quite a while now. Today is just the day that they start getting substance.

Probably just the usual stuff. I've been hammering mine all day and it's still cold to the touch.
