Is it possible to update my iPhone 6 to the latest iOS?

Won't happen: Unless your iPhone "specifically" is at Least 6s, 6sPlus, or

any version SE (1,2,3 gen), 7, 7Plus, 8, 8Plus, XR, XS, XSMax, all models

of 11, 12 and 13 series.

A recent update for iOS15.6 should still apply to these models. However

several older version iPhone would be dropped; as the transition to iOS

16.x leaves them to less features, and then, to historical past.

An iPhone 5s, 6, 6Plus can upgrade to their final iOS12.5.5 level only.

I have been trying to update my iPhone 6 for some time now but for some reason I’m realizing that no matter what I try or how I try my phone still refuses to install or update to a new iOS version, is there any one that can offer help with this matter, I would really appreciate it.

iPhone 6 cannot update past iOS 12.

That update is not supported, and is not possible.

The next version of iOS, iOS 16, is arriving later this year, and will minimally require an iPhone 8.

iPhone 6 cannot update past iOS 12; not supported, not possible.
