Yes my phone gets very warm, and doesn’t really charge, just barely maintains the level. My wife’s iPhone seems to work slightly better, but frustrating.
The location makes it easy to forget your phone there. I usually drop the lower screen down and forget about the phone only to realize it's about to melt when I do grab for it.
I can never find one that will work with my case and pop socket attached…not worth pulling the case off. I just plug it in. Not like I’m going anywhere while I’m driving…
