My experience has been the opposite. Battery life has improved for me. Overnight battery drain was the biggest stand out. And no, I do not have sleep standby optimisation on. I keep keep it off as my alarm didn’t sound of twice. And that was two instances too many. All I got was a “missed alarm” notification.
Usually using up 10% or less sitting idle overnight. And has been consistent after letting it do it’s own thing for a few days post update. I end the work day with a higher battery percentage daily.
