OK, so I’ve done a stupid thing.
I cleaned my iPhone with a damp cloth and stupidly plugged it in to charge overnight without waiting for it to fully dry out. I was awoken to a burning smell at 5am the following morning, the charger and ihone were red hot, when I disconnected the charger the contacts were glowing red and smoking. Surprisingly the iPhone still worked for the entire day, up until the battery died, now the screen is blank and the phone won’t charge up.
Any advice? Maybe the battery needs replacing? The fact it still worked gived me some optimism that the contents (photots, contacts, ect) can be saved. Thanks
