I have iPhone 6, and it's fine with iOS 12.5.4 released in June 2021. I'm thinking about upgrading, but the current situation is still fine. The phone still works very well, and I use it a lot. Safari, YouTube, Reddit, podcast apps, maps apps, notes, messaging apps, etc. still work about the same. Photos would have better quality on a newer phone, but overall not a big change for everyday use. These newer displays look nice though. I'll be forced to update when enough apps (not Apple, but third party) stop working because they no longer support iOS 12. Currently, there are only 7 apps out of over 200 that I have installed that don't support iOS 12. So I have to run an older version of these apps. Eventually there will be many. And the older versions of the apps will eventually stop working as well (if they connect to some web APIs that will be deprecated). This is what forced me to upgrade from iPhone 3GS to iPhone 6 last time.
