Thank you. I had this experience with two separate 5watt Apple chargers. All this time thought it was just me.There is no reason to use the 5W brick these days....I tried one out on my 15PM for a bit and it yellowed and nearly melted from how scorching hot it got trying to charge the phone. Meanwhile the 20W does it without breaking a sweat and the phone barely gets any warmer than it would with the 5W. I carried on using the 20W for something like a year and a half on the original battery charging only via the 20W and my USB port in my truck, and the phone continued to have 100% battery capacity for something like 330 cycles. There is absolutely no evidence to support charging via 5W helps anything long term, and as such there really is no logical reason to limit yourself to 4-6 hour charge times with the tiny cube anymore, especially when doing so gets it as hot as it does.
Those things got BURNING hot - to the point where both yellowed visibly (wish I had taken pictures). I put one on a Kill-A-Watt and it outputs more than 5w - and I think that's where the problem lies.
Those with 5w adapters - after an hour - should test the heat output of those things - mine were BURNING hot. That's not efficient or sustainable long term.
