In my pixel 5 for the past 2.5 years I charged using the "adaptive battery" slow charging function. (Which charges the phone in like 6 hours).
And during the day I charged up to 80% or 90% when my battery was going low for the rest of the day.
Also I was charging the phone every 2 or 3 nights because in the pandemic I was not using it a lot.
I think now the battery life is about the same. Maybe 5% worse than new. But it is also hard to test this because the os and the apps and the usage changed between day 1 and today.
An app called "Batt" reports 564 charging cycles though.
