Another Pixel 4A user here. Still haven't installed the marvelous update. But it'll be installed the next time I reboot. No way to stop it.
I have never had any battery issues. Now Google wants to effectively brick my beloved phone? And giving me $50 for the trouble. What. The. F. is going on.
I've requested the $50, shall be paid out within 18 days they say.
So sad. I really like (soon liked, probably) my 4a.
