thehellboy What raised my attention was:
apply the only change not related to the Pixel 6a battery workaround from the August 2025 Pixel kernel drivers obtained via GPL source request
But the "not" means that the battery changes were not shipped in this release.
Can you provide more details about the phenomena you have observed?
Have you tried multiple chargers? Multiple cables? What is the value of the setting for "USB-C port" in "Security & privacy", "Exploit protection"? If you power the device all the way off and plug it into a charger, what happens?
