iphone 5 wont turn on, charge or connect to itunes
My daughters iphone 5 is about 18 months old, she's recently had problems with the battery draining from 100% - 0% in a matter of a couple of hours even when not in use. Last week the battery drained and wouldn't charge, i tried everything i could think of and some things i found on the net. Yesterday i took it to a repair shop and they tested the battery, the battery was dead and he couldn't get it to charge. I decided to buy a new battery and hoped this fixed the problem. The phone charged as normal and everything was fine but today the phone died in a few hours and now wont charge again.
I've tried holding the home and power buttons for different amounts of time.
I've toggled the volume buttons,
left on charge for over an hour in the wall
I've cleaned all the conections and found no dust or anything.
I just can't get it to do anything.
I've connected it to my laptop but i can't even get itunes to recognise the phone, it's now been conected for a couple of hours and nothing is happening.
I've tried different chargers but as the chargers work with my own phone it can't be a faulty cable.
Is therre anything else i can try?
iPhone 5, iOS 7.1.1
