After I updated my Pixel 6A, I noticed it comfortably lasts 1,5 - 2 days with light use (music streaming + Bluetooth, youtube, comic book reading, occasional maps navigation etc).
Before the update it lasted about 1-1,5 days with the same amount of use.
I don’t have any screenshots to verify this (from accubattery or sth similar), so take this as anecdotal.
