Apple

Hey! Galaxy Note 10+ owner here,and been really considering switching to apple and Iphone 15 pro. Two biggest reasons for my change would be 120 Hz screen and a smaller phone in general. So my question is,how is the "promotion" on Iphone 15 pro with the latest updates? I did some research and apparently not all apps run with 120hz and in general the refresh rate changes a lot to conserve battery. I would prefer my next phone to run at 120hz pretty much all the time. So any info would be apperciated. How is the refresh rate on social media,general scrolling,news reading,videos,gaming etc. Thanks in advance!
