There are interesting things in laptop and phone charging circuits over the past 5 years. It's nothing to do with cooling but rather charging circuits with direct hardware level access to allow specific iterations of under and over voltage.

Every single laptop and phone with USB-C power circuitry for power input and output has this design and its not a fucking coincidence. 

I'm sure the same people who made stuxnet also influenced every hardware ODM/OEM to adopt this strategy of being able to remotely turn your lithium battery powered device into an bomb just like the pagers.
