The noise has to be coming from the phone then... I contacted the manufacture but their response wasn't particularly helpful as their only suggestions were to power cycle the phone or do a factory restore and i've already done that. To be fair though I didn't tell them I had done that. Anyway...
General question for the experts... My mobile phone has a 3.7 V Lithium Ion battery, it has been in use for about two years now. I have a name-brand coil wireless charger for the device and have been using it for well over a year. Within the last few months, on rare occasion I will be charging...
