Samsung Galaxy S23: Compact, Powerful, and Still Worth It in 2026

If you want a compact, powerful phone without paying top-of-the-range prices, the Samsung Galaxy S23 is hard to beat in 2026. It runs the Snapdragon 8 Gen 2 for Galaxy, the same chip found in Samsung's premium 2023 lineup, inside a 6.1" body that fits comfortably in one hand.

In 2026, a refurbished Samsung Galaxy S23 starts from around €279 on refurbed. The S23 remains one of the most in-demand refurbished smartphones in Europe, with stock across platforms shifting quickly as interest stays high. Refurbished means the device has been professionally checked, cleaned, and reset by a verified seller. Every function tested, every worn component replaced where needed, before it reaches you.

The S23 also runs the full Samsung Galaxy AI suite, including Circle to Search, Object Eraser, and Live Translation. These are features most people associate with flagship phones costing €700 or more.

Whether you're upgrading from an older Android or looking for a smaller alternative to newer oversized flagships, the Samsung Galaxy S23 deserves a close look.

Every Samsung Galaxy S23 sold globally runs the Qualcomm SM8550-AC Snapdragon 8 Gen 2 for Galaxy. There is no Exynos variant for this model. That means consistent performance across all markets and all units. If you're buying refurbished, the chip you get is the chip Samsung intended.

The Snapdragon 8 Gen 2 for Galaxy pairs a 1×3.36GHz Kryo Prime core with 4×2.80GHz Kryo Gold and 3×2.00GHz Kryo Silver, backed by the Qualcomm Adreno 740 GPU.

In gaming, the S23 runs PUBG at 120fps with no overheating documented. Call of Duty Mobile and Fortnite run without frame drops. In 2026, this chip handles everything smoothly: multitasking, gaming, AI feature processing. It does not feel like a 2023 phone.

The 8GB RAM is sufficient for daily use. Heavy multitaskers who keep many demanding apps open simultaneously may occasionally feel limits, but for the vast majority of use cases, performance is not a concern.

The Samsung Galaxy S23 has a 3900 mAh battery. Through a standard day of social media, messaging, some streaming, and navigation, the S23 finishes the day with charge to spare. Lighter users can stretch to 1.5 days.

The honest limitation is charging speed. At 25W wired, the S23 is slower than competitors offering 65W or 100W in 2026. If you need a fast mid-day top-up, you will notice the difference. This is a known trade-off at this price point.

15W wireless charging is supported. For overnight charging, this works well and keeps the battery at 100% for the morning without the need for a cable by the bedside.

If you plug in overnight, the S23 starts every day fully charged. For most routines, the 25W limitation is a minor inconvenience rather than a dealbreaker.

The Samsung Galaxy S23, like some earlier Samsung OLED panels, can develop a vertical line on the display. It is typically green or pink and appears at the edge or through the middle of the screen. This is a documented failure mode on a subset of units.

The line does not damage the device or affect other functions, but it is visually noticeable and can be distracting.

When your unit arrives, inspect the display thoroughly under different brightness settings and backgrounds. Check for any faint vertical lines.

Buying from refurbed means your device has gone through quality checks before shipping. You also have a minimum 12-month warranty and a 30-day return window. If a display issue appears after delivery, you have a clear path to resolution.

Being an informed buyer is worth the two minutes. This section exists because transparency builds trust more than silence does.

Compact phone fans: the Samsung Galaxy S23 is one of the few phones in 2026 that combines Snapdragon 8 Gen 2 performance with a 6.1" form factor. If one-hand use matters to you, the options are limited at this performance level, and the S23 is the standout.

Casual to enthusiast photographers: the 50MP main sensor and 3× optical telephoto deliver strong results in good lighting. If most of your shots happen in daylight or well-lit conditions, you will be satisfied. Night photography is capable but not class-leading.

Galaxy AI curious: Circle to Search, Object Eraser, Live Translation, and Gemini are all active on the S23 from around €279. If you want to explore Samsung's AI ecosystem without the S25 price tag, the Samsung Galaxy S23 is the most affordable entry point.

All-day battery users: the 3900 mAh battery covers a full day reliably. If two-day endurance is important to your routine, scroll down to the S23 vs S23+ comparison below.

Both the Samsung Galaxy S23 and Samsung Galaxy S23+ run the same Snapdragon 8 Gen 2 chip and carry identical camera systems. The decision comes down to how you use your phone day to day.

For buyers shopping refurbished in 2026, three years into this phone's lifespan, there is a practical advantage to considering the S23+: at 80% battery health, which is typical for a three-year-old unit, the S23+'s larger 4700 mAh pack roughly matches a brand-new S23 in real-world runtime. The larger battery has been degrading from a higher ceiling.

Some S23+ users also report that battery life peaks after approximately two weeks of regular use as the system calibrates. Worth knowing before drawing conclusions from the first few days.

Is the Samsung Galaxy S23 still worth buying in 2026?

Yes. From around €279 refurbished, the Samsung Galaxy S23 delivers Snapdragon 8 Gen 2 performance, a capable 50MP camera system, Galaxy AI features, and a compact 6.1" build that holds up in 2026. One major software update remains, which is worth noting, but not a dealbreaker for most buyers.

What is the difference between the Samsung Galaxy S23 and S23 Plus?

Same chip, same cameras. The Samsung Galaxy S23 has a 6.1" screen, weighs 167g, and has a 3900 mAh battery with 25W wired charging. The Samsung Galaxy S23+ has a 6.6" screen, weighs 195g, and has a 4700 mAh battery with 45W wired charging. The S23+ also adds UWB connectivity. At around €279 versus €330 refurbished, the question is whether the larger battery, faster charging, and bigger screen are worth the difference for your use.

What is the OLED line defect on the Samsung Galaxy S23?
