IOS 14.5.1 Dramatically slowing down data & Wifi

I suppose my iPhone XS Max had just updated to the 14.5.1 but I hadn’t noticed. It had done it overnight from the 9th to the 10th since my phone connection was working perfectly fine on both Data and WiFi. The next day on the 10th, my connection was garbage. Wifi and data, my phone was connected but kept showing no internet connection. I tried to get on many different apps and they never loaded I though there was something really wrong with my phone. I went ahead and I upgraded to the 12Pro Max and I started setting it up. It downloaded 14.5.1 as I was setting it up, well guess what? Now my new phone is doing the exact same thing. Only it’s not so bad on this new one but still pretty bad. I go to the settings and it shows that I’m connected to the wifi but the bars don’t show on the top, it shows the data bars, AND also both are very slow. At least this phone kinda loads a little better. Anyone have the same experience!??
I have exactly the same issue with my XS Max. One day it went bad and later somehow repaired itself, a few days later it happened again and the internet is practically not working.
My iPhone Xs Max keep crashing on games and dramatically slowed down

I have the IPhone 12 and my software version is 14.6 and I think that my data are extra laggy than they must to be (I haven’t test it with WiFi because I am on vacations). I don’t know if the problem is the software or the phone but I believe that this isn’t Normal.
