    If I use my ipad2 charger on my iphone4, will it screw up my battery? I have seen many posts about this but no one gives a definitive answer. I known the iPad charger is a 2.1 watt charger and will charge the battery much quicker, but will this ultimately damage my iPhone as it was made to charge over a 1 watt charger?

    Any help will be appreciated.

    ive been using my ipad/ipad2 charger on my iphone 4 since it has come out. I havent had any battery issues. I also asked a genius this same question when I while I was in the store last week, and he said it wouldn't do anything. Just do not use the iphone charger to charge the ipad

    exactly. Safe to use and no issues. The iPad charger actually charges the Iphone a bit faster than the stock charger.

    The ipad won't charge from an Iphone charger Not enough juice.

    You guys should really do some searching before you start posting. Or at least have some real world experience.

    The iPad will charge from a iPhone charger just at a slower rate. It's reverse for iPad charger to iPhone.

    You seem qualified to work at an Apple store. They usually have no idea what they're talking about. You'd fit in quite well.

    Nope, it just charges slowly. It says not charging when plugged into a computer with a USB port that doesn't provide enough power. Even then the iPad will charge very slowly when the screen is off. If you turn the screen on you will see not charging though, and the battery will go down.

    If you're using it, yeah. That charger can't give power to run it AND charge the battery.

    But if you put it to sleep then the iPad will (slowly) charge from the iPhone adapter.

    From my experience the iPhone charger does charge the device while it is being used. The icon at the top will indicate it is charging, but it will charge slow. As I mentioned above, if you have it plugged into an old computer it won't charge while it is being used and will indicate "not charging". In that case it will charge slowly if you put it to sleep.

    I use my iPad charger to charge up my iPhone occasionally. It'll charge quiet a bit faster but I've noticed that the battery seems to drain faster as well. Not sure why.

    Look here where it says "This accessory is compatible with the following:"

    The iPhone 4 is on that list.

    The smaller iPhone 4 charger DOES charge the iPad (I know this first hand) but it does indeed charge a lot slower than the 10W iPad charger.

    I had the same results when I charged my 3GS with the ipad charger. Battery went down real fast to a point where it just turned off. Not using it anymore on my phone. ;)
