    Or do they both give the same amount of charge that lasts the same time??? Just wondering this is my first iphone and thought maybe a charge through the mains would make it last longer?? Or am i wrong?

    Its the same.

    Any insight as to charging techniques to keep battery performance high? Do you charge it until 100% then unplug, charge it overnight?

    It is not the same (if that’s what he was asking). The wall gives you double the current of the USB.

    Edit: No need to unplug. Just charge it at the end of the day. Try not to ever let it die, until a month or so has gone by. The main thing is to keep the ions moving in the battery.

    thanks thats very helpful......i'll defo do that........

    to the rest of u......i didnt really care how long it takes to charge......not fussed if one charges quicker than the other......was more interested in whether charging through the mains was more efficient for the battery (to make it last longer) than the usb. I had an old phone that when charged through usb used to drain the battery VERY quickly compared to mains.....just wondered if this may have been the same?
