Which iphone 12 pro do you have, I also have the 12 Pro and I'm ready to upgrade just based on the lack of storage and other oddities that I feel would be addressed by getting a faster phone.
WhatsApp can become unusably slow for minutes at a time, apps I just used will close due to limited RAM; mind you I don't have a single game on my phone, I have bank apps, store apps, and messaging apps mostly, along with various utilities apps, like PW manager, smart home stuff, and various productivity apps (MS, Google suites). Nothing feels like it should be this terrible, and yet somehow its become a little too slow and jittery.
