    Hi - got my new iPad on Friday, and it ran hot straight away. I've seen posts online that say that they run hot after a few hours, not straight away.


    Anyhow, I totally discharged the battery, recharged overnight, and then disabled iCloud on it - it seems to have made quite a difference. It's still al little hot, but nowhere near what it was like before.


    I think iCloud syncing may be the culprit! Disable it and see if it makes a difference.

    Mine gets pretty darn hot as well.

    I followed the advice of an earlier poster and cranked down the brightness of the screen.  I've had my iPad running for 3 hours this morning doing normal things and the heat level is much less than yesterday.  I set the brightness level down by about 15%.  I actually like the screen a bit dimmer . . . easier on the eyes.

    So it sounds like the quad-core graphics are getting too amazing.

    Mine gets burning hot without using 4G -

  • amytula Level 1 (0 points)

    Every one says turn down the brightness - its already abot 70 brightnes of the ipad 2 when both are turn to full brightness -

    Great idea - lets turn it right down so it runs cool and then use a flashlight to use it lol


    pretty un-impressed so far - stick with ipad 2 and mobile hotspot from t-mobile.

    People want faster graphics, more powerful processing, yet better battery life.


    That is technically possible, but something always has to give..... hotter chip temperatures.


    It's not likely to damage anything - as safeguards i.e. temperature sensors would reduce CPU/Graphics speed, if temperatures became too high.

    Something doesnt always have to give. Better technology leads to improvements without sacrificing any of that.


    Graphics performance between the iPad 1 and iPad 2 was a huge step but we didn't have any heat problems on the iPad 2 did we?

    Intel Pentium 3 throttle down temp  - temperature when chip auto throttles number of cycles to reduce heat, is 70 celsius.


    Intel i7 - throttle down temp 100 celsius.


    Operating temperatures of most chips have increased the more powerful they get. When used (especially hard), chips generate heat - where else could the heat come from, possibly the battery, but doubtful.


    If you do a search for ipad temperature warning - you'll see overheating problems were reported on earlier models.


    All Apples machines run 'hot'. It's impossible for me to keep my Macbook Pro on my lap and 'work it hard', without a cooling pad between my legs and the Macbook.

    You're comparing different things. These processors run on different dies and what iPads and iPhones are on are simply ARMs which essentially generate less heat too. In fact an iPad contains a low voltage version of the A5.

  • CliveS Level 1 (15 points)

    Of course they are different things.


    But the point I am trying to make... every new model iPad, Macbook, iMac has more powerful chips and history proves that the vast majority of 'newer', faster chips the operating temperature increases.


    In a PC or desktop application, this can be managed by larger heatsinks, biggers fans. Not so in iPads, Macbook Airs, etc.


    Why else would people complain of high temperatures every new model that comes out? Where else is the heat coming from?

    ya i have the 64 wifi and it doesn't get really hot, just warm

  • CliveS Level 1 (15 points)

    I found reducing the screen brightness also reduced overall temperature.


    I would have liked to see a 'resolution setting' for the new iPad. We are pushing the limits of what the naked eye can see. Do we need such resolutions for a 9.7" screen?

  • blitzteh Level 2 (175 points)

    like what some people are saying its due to the new 4G chip, the later generations were using technology not as complex as the current gen. It is true that great technology should go hand and hand with no sacrificing anything but that is a very dreamy perspective. Maybe in the future when we develop materials that cool off faster than what we are using now or use lesser energy. But today, that is just not realistic.

    Except it's occurring on wifi only models also (like mine)...
