    Ok, well I got an iPhone 4, and my little sister is using my old iPhone 3G as a iPod Touch. Well the iPhone 3G was dead and my sister went to go plug it into the charger. When I entered my room, I saw the iPhone pluged into the iPad 15 (?) watt charger.

    I took the charger cable out, and it was at 100%. It went from 0 - 100% in 45min.

    First question, is my battery screwed in anyway? Is it ok?

    Second question, I started to play with it a little bit and within 5 min of use, it dropped over 15% :eek:...I wasnt even playing a game or watching a video, it was just on the homescreen, full brightness.

    I watched it go down 1% every 10 seconds...

    I use my iPad charger for my iPhone sometimes. I also notice it drains quicker after using the iPad charger. It does charge it faster though.

    watts don't match. definitely not suggested to use it as it could easily damage your iphone or give false battery readings.

    You should be fine if it just was one time. Aren't the apple chargers smart chargers?

    Dockingbay94 is incorrect. All the units have smart chargers on board. They will use only the power they need to charge and no more.

    You can safely use your iPad charger to charge any iPhone. It is not recommended to use the iPhone Charger to charge the iPad unless you turn the iPad off first. I have done it and it works but it takes quite a bit longer.

    I have also charged my iPhone 4 from my iPad charger several times with absolutely no problem at all.
