I end most days between 50 to 60 % level left on my A53. If yours is brand new it can take a few days to adapt to your usage. The first 4 to 5 days when I got mine, it wasn't great but soon got better.
It maybe worth doing a cache partition wipe or a factory reset now it is on Android 13 to see if that helps. You can also use the diagnostic test from the Samsung Members App to test the battery health.
