Whenever I charge my iPhone 12 Pro Max, it shows a thermometer symbol telling me the phone needs to cool down, and the phone gets very hot. This happens when the charging reaches around 50%. I’m using a 20W original Apple charger. When I switch to a different Android adapter and Apple cable, this problem doesn’t occur, but it takes a lot longer to charge. I bought my phone about seven months back . Any solutions ?
