people who are nice which is a bunch will still put the phone in airplane mode therefore reducing charging rate/max charge level reducing the likelihood of thermal runaways.
I just checked with my newish Xiaomi 4X. I activated the airplane mode and by using the company charger it went to 97% and that because I unplugged it. And ISTR that using the airplane mode it charges in less time - not sure if the charging is faster or much less energy is used from the mobile. However the temperature of the mobile did remain on the cool side.
