I leave my phone (turned off) charging all night and every time I turn it on the battery shows 88% (although led light is green). Then I leave it on, plugged in for 30 minutes, and battery level goes up to 100%. It always happens the same.

It seams impossible to fully charge the battery while phone is off. Is that normal?

Just give it a shot and repair your device, that will help narrowing down possible causes.

Can you try other chargers or USB cables and see if the same happens?

I could, but the very same cable and charger work fine to charge the battery to 100% when the phone is on. I don't think they are the problem. They are the charger and cable that came with the phone, by the way.

Thanks!

Yeah I agree, but it's a strange problem because logically phone will charge faster and more fully when switched off, so eliminating the possibility of a defected charger/cable will help troubleshooting. Other possibilities can be software and this may suggest that you try reinstalling your software and go through the process of backing up etc.
