Galaxy S24 vs Galaxy S23
An honest, side-by-side look at the Galaxy S24 vs Galaxy S23 decision — specs, camera, battery and refurbished price — so you can buy the right one with confidence.
Samsung's Galaxy S24 refined a already-excellent S23 rather than reinventing it. The headline additions are Galaxy AI, a brighter and slightly larger flat screen, a faster chip and an industry-leading seven years of software updates.
The Galaxy S23 keeps the same compact, one-hand-friendly footprint and the same core camera system, at a lower refurbished price.

The verdict
The Galaxy S24 is the better long-term buy thanks to its seven-year update promise, brighter screen and Galaxy AI tools like live translation and generative photo editing. It's the more future-proof compact Android flagship.
The S23 is the value option and still an excellent phone — the same 50MP camera and premium build — but its shorter update window and dimmer screen are why we lean toward the S24 for most buyers.

How long will the Galaxy S24 get updates?+
Samsung promises seven years of OS and security updates for the Galaxy S24 — one of the longest support windows in Android, and a key reason it ages better than the S23.
