It was fine this mmorning then went to plug it in and nothing happened
My Galaxy S4 mini did the same thing last night and today. I didn't drop or break the phone so I was puzzled why it suddenly stopped charging on any charger any cable. I applied the latest update I435VRUBOC1 and after updating and rebooting, it charges again. I suspect that the reboot fixed it more than the update. Maybe you can try pulling your battery and forcing a reboot????
