That was an interesting article. I live in the Philippines. I have never had a cell phone overheat. If fact I've never heard of one overheating from anyone I know. Everyone in my family uses a cell phone, all Android and one iPhone, about a dozen in total.. The one recommendation that stood out to me was don't leave the phone in the car, a good one. With a few exceptions I don't see this ever happening. Everyone here has a cell phone, on their person, it would very unlikely be left in the car.
