Iphone 12 pro ios 17.5 system data

hello friends, sorry for bothering, i have one question, after installing ios 17.5, in general, iPhone storage ios size is 11.28gb and system data i look at it all day and max size of system is 9 gb, usually 7.50gb🤦🏻‍♂️ before installing new ios, system data was max 5gb. So can you please give me advice, i cleared cashe and everything, lower system data size was 6.5 gb. I thought to erase iphone and restore, but first i’d get advice, is it problem, or do i have to pay no attention on it, because i am tired of checking it, or instead of this stop checking and keep playing and working on it. Thanks for attention and your time.
