What ends it first: typical hardware wear at this usage level. Security updates run to Sep 2030, so wear is the constraint, and wear is repairable.

Wear is what limits this one, so a battery or screen repair may be the cheaper move.

Battery health

This is the number that decides it. Everything below updates the moment you pick one.

iPhone: Settings › Battery › Battery Health & Charging. Pixel: Settings › Battery › Battery health. Samsung: the Samsung Members app › Diagnostics › Battery status.

A new battery restarts most of the wear clock. It does not move the security-update cutoff. Nothing does. Buying second-hand does not reset it either: a refurbished unit still has a battery of its original age unless it was actually replaced.
