Same with my 13 pro max. It is said that after an update, your phone will be more sluggish due to the phone settling and processing everything and then it should improve after a couple days but it seems to me it’s the other way around. Right after the update things seem fine and most of my phone running smooth and normal. Only after its been a few weeks and beyond that it begins with these bugs, glitches and performance drops. The only way i usually see most if not all problems go away is doing a factory reset. But having to do that after every update is obviously not ideal. Literally all other methods that I try either work temporarily or don’t work at all.
