    Actually, almost hot. Today I noticed that it was pretty warm. I use 3G all the time out in the field and never noticed this.

    I thought I read that the iPad works harder when using 3G?

    Or not...:eek:

    I'm a fairly heavy user Marie. Never noticed anything significant in terms of heat.

    Okay ~ me either until today ~ I was closing it up and noticed how warm it was.

    I clean it off and gave it a hug.:D

    All over, or was there a hot spot in particular?

    Come to think of it ~ it was only the left front that was warm. Funny you should ask that, Leigh. Why did you ask that? Trying to get inside that smart head of yours!

    You don't want to get in here, trust me! Are you sure it wasn't environmental being on the front? Sun shining on a spot through a window before you picked it up? The front should never get hot from internals!

    When heavy using, like Puffin browser or other heavy usage apps, mine will get very warm AFTER I finish using it. I just figured it's a heat dissipation thing. It does it at the top and bottom thirds of the entire back. It's only that way for a few minutes and will be slightly warm at most during use.

    I would not ever let my iPad in the sun! I remember though, Leigh, when I first joined this site ~someone told me that when 3G is activated it makes our iPads work harder...

    But that would be a hella lot of posts to go through to find that.:D


    Well this is good to know!

    I've not used 3G on my iPad yet but I would think since it uses more energy than wifi that if your signal was weak and the iPad tried to compensate, assuming it does that like a phone would, that the battery would work harder thus creating more heat.

    Interesting theory ~ I suspect it must be true as it happened to me.

    The power output of the 3G transmitter is quite low, although I've never seen the specs.

    I haven't used the iPad in this manner yet, but the iPhone gets almost too warm to hold comfortably when I run a GPS app and charge it at the same time (which is almost a necessity with the iPhone - the GPS seems to take a LOT more power than the 3G radio.) it seems to get to "full heat" in a half hour or so. I've had it set up that way for several hours at a time. It seems to get hottest on the upper back.

    Thinking about this last night you could be right about the 3G. As others have said, the iPhone does warm up particularly if I have been on a long call. Maybe if you were pushing hard for half an hour or so it was sufficient to generate some proper heat...
    Is it back to normal now Marie?

    Oh yes. It was back to normal before I slipped that puppy back into it's case, while still in my car.

    And you know ~ it might have happened before while accessing 3G, I just never touched the iPad directly, maybe. This time I just happened to.

    The iPad seems to be designed to dissipate heat quickly so I guess it would feel warmer since it's getting rid of the heat faster than say plastic.
    My Omnia phone( I still use it as a wifi PDA) CPU area gets warm enough to use as a hand warmer when I use it for any length of time, add in the battery heat and it's great on a cold morning if I forgot to bring gloves ;)
