Itune had an update to the Iphone software which downloaded into my phone through my computer. the software was Iphone software.
I charged the phone using the USB on my computer - it is hooked up now to recharge.
I am sorry but i think you misunderstood my query. the Iphone is charging up OK. however it is not holding the charge. the battery is draining very quickly with no usage. it was charged up last night and needs recharging again this morning. I have heard that Apple have had problems with upgrade software that causes the battery to drain quickly.
my phone was fine until this latest software 'upgrade'.
