wireless charging circuit faulty

I recently brought a qi charger base and receiver for my s3 and when it comes close to the base I get a message on the screen confirming wireless charging is taking place however it does not actually charge I have tried a few apps which show battery charger stats but each one shows different results. some saying charging some saying discharging .

I am thinking maybe there is a fuse somewhere on the motherboard for Qi charging and would appreciated if someone had a circuit diagram for this part of the phone
