Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
52% above the under-$300 median ($6.74/mo, dying phones excluded)
Our verdict
The big-screen S23 at ~$206 used buys a 4,700mAh battery, 45W charging and support to February 2028 — about $10 per month of safe use. Solid as a two-year bridge phone, wrong as a keeper.
Pros
- Big 4,700mAh battery and 45W charging — the practical upgrades over the base S23
- Still receiving monthly security patches as of mid-2026, with Android 17 to come
- 256GB base storage — no cramped entry config
- Snapdragon 8 Gen 2 remains quick and efficient in 2026
Cons
- ~20 months of security updates left — done in February 2028
- Buy-by date passed in February 2026; not a long-haul purchase
- Used S23+ stock is thinner than base S23 or Ultra, so condition varies widely

Frequently asked questions
Is the Galaxy S23+ still supported in 2026?
Yes. As of June 2026 the Galaxy S23+ is still on Samsung's monthly security update list, runs One UI 8.5, and will receive its final OS upgrade — Android 17 (One UI 9) — in late 2026. Security patches continue until around February 2028.
Should I buy a used Galaxy S23+ in 2026?
Only as a short-term phone. At about $206 used with roughly 20 months of support remaining, it costs around $10 per month of safe use — acceptable, and the 4,700mAh battery makes it the most livable used S23 variant. But anyone planning to keep a phone past early 2028 should buy something newer.
When does Galaxy S23+ support end?
Around February 17, 2028, five years after its February 2023 release. The S23 generation carries Samsung's 4 OS upgrades + 5 years of security updates promise; the 7-year window started a generation later with the S24.
Galaxy S23+ vs Galaxy S23 used — which is better value?
They share the same chipset, cameras and February 2028 support cutoff, so it comes down to ~$30: the S23+ adds a much bigger battery, 45W charging and 256GB base storage for around $206 vs $175. If the size suits you, the Plus is the better used buy.
