What to look for in a phone if you keep them a long time
Should you buy at all?
If your current phone still gets security updates and the battery is healthy (or worth a cheap replacement), keep it — a battery swap is far cheaper than a new phone. Buy new when updates have ended, or the phone can no longer do what you need.
The spec that actually decides longevity
Cameras and chips barely limit how long a phone lasts. Software support does. A phone stops being safe to use for banking and email the day it stops getting security updates — so the update promise is the number to check first. The good news: it has improved dramatically.
- Google Pixel (8 and later) and Samsung Galaxy S24 and later promise 7 years of OS and security updates.
- Recent iPhones aren’t given a fixed number, but Apple typically supports them a long time (roughly 5–7 years in practice).
- Budget phones vary widely — some cheaper Android models offer only 2–3 years, which caps how long you can safely keep them.

The two-year rule
Don’t buy a phone with under two years of security support left. That rules out end-of-line budget models and older stock being cleared cheaply — the “deal” isn’t one if the phone loses updates next year.
What else helps a phone last
- A replaceable battery / affordable battery service. The battery is the first thing to wear out; easy replacement adds years.
- Enough storage (128 GB+). A phone that’s always full ages badly and can’t take updates.
- Solid build and water resistance — survives the drops and spills of a long life.
- Decent RAM (6–8 GB) so it stays smooth as apps get heavier over the years.
What matters less
The latest camera sensor, the fastest chip, and the highest refresh rate are nice but rarely why you’d replace a phone. Longevity comes from updates, battery and build — not the headline specs.
Refurbished is a strong option
A refurbished flagship from a couple of years ago, from a maker with a long update promise, can be excellent value and still have years of support left. Apply the two-year rule and our used-buying checklist.
Frequently asked questions
Do I need the newest model?
Rarely. Last year’s flagship with a long update promise often beats this year’s mid-ranger with a short one — and costs less.
iPhone or Android for keeping a long time?
Both are strong now. Pixel and Samsung’s 7-year promises are explicit; Apple’s long support is proven in practice. Pick the ecosystem you like, then check the update window.
Where do I check a phone’s update promise?
The manufacturer’s site states it, and our support tracker summarises end-of-update dates for popular phones with sources.
