Quantum Yes I've been on stock Android for a year, and I've been using GrapheneOS for more than a year for privacy/security reasons.
I'm very thankful to this team for their continues hard work.
I have friends who switched to Pixels because of me, one of them has a 6a as well running stock pixel OS and was affected by the battery program back in July when QPR1 was still beta and ended up switching to a pixel 8 pro.
I've charged mostly overnight and tried not to use the phone while charging during the day if needed, also I've tended to keep the battery between 30/40-90%.
Battery has been pretty amazing for its age and I've never had heating issue when charging.
