Not sure if it's on me, but on my Pixel 6 the function to limit charging to 80% doesn't seem to work anymore - if anyone with the current Alpha can check too?
It keeps charging past 80%.
I did let it charge until it hit 100%, unplugged it until it discharged below 79%.
After that I plug it in to charge, it charged past 80% (83) again.
Sorry if it's known already.
