My daughter has an iphone 6, which when charged only 'lives' for about an hour or so and dies. It's out of warranty and she's spoken to apple, done all the updates and all the carp they get you to do. Theyve tested it and said the problem is the phone and not the battery. They cant diagnose the fault and have offered her a new 6 for £300 or £120 for a trade in for a newer model. Anyone had similar and found a fix ?

........and before any Apple haters join the thread.........Yes I know !!
