FP4 battery life got worse after Android 13 update

Dear all, The battery life of my FP4 got noticeably worse after the Android 13 update. I recently bought a new battery to get better battery life and it my battery was lasting around 1.5 days with normal usage. After the update to Android 13, I barely make it through the day. One theory I have is that the newly added animations when opening and closing apps are more expensive. But of course this cannot be the only reason. Has anyone experienced this? Is there a way to disable these animations…
