    Charging Issue

    I have an iphone 4,4s an ipad 2 and now an ipad3. All but the ipad 3 make a vibration to let me know that the device is actively charging. Is there a setting for this on the ipad3 or have they done away with this? I am only charging the ipads directly from the wall outlet.

    That is strange

    I have the new iPad, iPad2, iPad, iPhone4 and iPhone 4s. None of them vibrate as you describe.

    My iPad 2 does this too, feels like a feint buzzing, almost like a mild electric shock......I remember a discussion about this some time ago, before I got my iPad 2 I think.

    Can't say I've noticed anything on either my iPhone4s or my iPad1 or new iPad 3

    I get this on both iPad 2 and 3, I'd describe it similarly as a mild electric shock buzzing....

    It is not a feature.

    Any vibration you are feeling while charging is a byproduct of the process. It can vary from nothing to noticeable depending on minor differences in the components and assembly of the device.

    If you pay attention you'll notice it in may electronics and electrical devices; especially power supplies. My iPad's power supply has a mild vibration. My iPad does not.

    I am surprised that it is happening in any iOS Device itself. I wonder what circuitry is causing it. The usual cause is the transformer that converts household AC to whatever else is needed, and that is external the iOS devices. Or is it possible that those who are feeling it are charging in a dock or some other method that could be physically transmitting the vibration to the device? Even having both in firm contact with an intermediate like a table might to it.

    My devices give off an audible tone to let you know they have started charging. There is no vibration, however.

    I don't use a dock and the charger is not on the table with my iPad, I also feel it to a lesser extent in my iPhone. It doesn't really bother me until my hair starts to stand on end!

    I suspect it might be an effect from the power supplied. 50 Hz may be more inclined to do this than 60 Hz, for example. The chargers are suppose to be universal, but there are small differences in the DC power provided.
