Before your iPhone may have its system updated, you need

know which update level -- yours may be able to go up to.

Given known hardware limits, wishful thinking cannot

extend the useful life of these products beyond reason.

Often your iPhone may require an Update by Wire. The USB

to Lightning cable, these phones have shipped with; also is

the charge cable. Each iOS instruction page shows blue links

this includes How to update by Computer; instead of WiFi.

to latest iOS 16. ~There are older phones, those cannot be

updated to later than those compatible to their hardware.
