iPhone 4 won't charge!
Hi, I've had my iPhone 4 for 1 year now, and until yesterday it was working perfectly. But yesterday I noticed that it hadn't charged overnight although I had plugged it in for charging. However, when I plugged it into my MacBook, I could still transfer data. But it was not charging. Instead of the charging (zig-zag line) icon on the battery symbol there was a plug icon on it, showing that it was completely charged. But still it was showing 20%. And now, this morning my iPhone is completely dead and will only switch on when I plug it into my wall charger. As soon as I disconnect it from the charger, it switches off and does not turn on anymore.
What do you think: will a battery change fix the problem? Thanks for your help!
