Depends on the videoWow, the RAM management is quite bad on the iphone 11. I was secretly wishing for apple to include more RAM, but they stuck with 4GB RAM. Usually android phones require more RAM, but I feel that we are at a point where more RAM is needed on iphones as the optimisations on IOS is not enough. I feel that ever since IOS 11, more RAM is needed as my old iphone 7 started to run into RAM management issues since IOS 11, and iphone 8/8 plus/X at that time also had apps reloading a lot, and Iphone Xs never quite solved that issue even with 1 GB more RAM.
just seen a YouTube video where the Note 10 plus had more refreshes than the iPhone.
