@[email protected] holy fuck it will, what a stupid os
@jleedev @phooky if it’s theoretically receiving power but still losing capacity, the system battery menu should change to say “not charging” instead. But it probably still merrily drains itself because the USB-PD spec doesn’t provide a spec-compliant mechanism to tell if you’re draining from yourself afaict.
@s0 @jleedev @phooky Even then, people can still (and did) build circles of devices where such data would be lost (A->B->C->A)

An easier metric might be "what is my net charge?" and to maybe ask the user if they want to stop the drain (they might have legitimate reasons, e.g. keeping a USB-C display powered for a short time, even if the power supply won't support it indefinitely)
