You mean you have an iPhone 6 and it's working fine on iOS 11 with a clean install?
That's a good news then, maybe I should reset everything and reinstall to see if that works.

Historically speaking, we would expect the 6 to be supported by iOS 12, possibly by iOS 13 and unlikely by iOS 14.
The current trend for current iOS devices is five generations of software support with the iPhone 4S, 5 and 5S all getting five years.[1] The only recent exceptions are non-flagship models that used "old" parts at the time of release (iPhone 5C and iPad mini 1) which only got four years.
