I didn’t notice any battery life changes on/off but turning it off did appear to smooth out some animations when switching apps. However apps just get killed too often and have to completely restart so I turned RAM Plus back on but to the lower 2GB setting.

Main pro: more of your background apps stay open, so if you’re playing a game then switch apps a couple times, have lunch and come back to the game few hours later it resumes from where you left off instead of restarting the app

It’s not a world’s difference at all. But Android lets me play 2 audio streams from different apps at the same time and lets me install apks so that wins it for me.

It’s not a big deal. I have a mix of Apple and Samsung devices and it’s fine (iPad Pro, MBP, Galaxy S22, Galaxy Watch, Galaxy Buds). It’s actually nice to be able to experience both sides, more new things to try out and be excited about. Switch back to iPhone in a few years to see what’s new on that side.
