iPhone 5S doesn't charge (sometimes)

[MaxSmarties]

My wife's 5S (quite new, bought last september) in the last 2 months is having an issue. Not so often, just sometimes, but it just refuse to charge when connected to the charger. I tried several chargers (all Apple's original chargers) with no luck.
If I switch it off and reconnect it to the charger, it charges normally....

Any advices ?
It still is under AppleCare (2 years in Europe) so the idea is to have it checked by Apple.

My youngest son just went through this a few days ago with his iPhone 5S. He switched chargers after a couple of days and voila! It began charging normally. This is the only time it has happened, and hopefully, it'll never happen again. Why it happened in the first place, I do not know, unfortunately.

Have you tried to clean the charging port? It's a dust collector

It was my first guess... But it seems to be clean.

I don't know, I'm considering the opinion to fix an appointment at the Genius Bar

It happened twice at my wife in the last two months. And in her case, switching chargers didn't work (I have 4 chargers at home: two iPhones and two iPads).
Just rebooting the iPhone is the solution

An appointment to genius bar might be your best option if its still under AppleCare.

My friend thought his was clean too. Then apple tech pulled out enough to make a pillow. Now it works fine.

Yep. AppleCare is 2 years in Italy.

It wouldn't explain why it works after the reboot...
Next time it will happen, I'll fix an appointment at the Genius Bar.
