There is a hazard in using any battery.
I use a 6a, using it right now. I have no intentions of replacing it until it becomes EOL in 2027, just under two years away.
My device behaves impeccability, shows no signs of overheating etc. It amuses me that a Pixel range has a problem, just before a launch of a new model.
Oh there's an idea trade in my P6a for a P10... No f@#king way...
