About the Samsung Galaxy S23 Ultra
The Samsung Galaxy S23 Ultra was the most complete Android phone of 2023, and in 2026 it remains a remarkably capable flagship that still competes with current-generation devices. Its 6.8-inch Dynamic AMOLED 2X display delivers stunning visuals with 1,750 nits peak brightness and a silky 1-120Hz adaptive refresh rate. The Snapdragon 8 Gen 2 for Galaxy chip continues to deliver excellent performance and power efficiency, handling everything from multitasking to console-quality gaming without breaking a sweat. The camera system is genuinely class-leading: a 200MP main sensor produces extraordinary detail, the 12MP ultrawide captures expansive scenes, and the dual telephoto setup with both 3x and 10x optical zoom gives you reach that even the S24 Ultra cannot match, as Samsung swapped the 10x for a 5x lens in its successor. The built-in S Pen transforms the phone into a note-taking and creative tool, a feature now discontinued in the S25 Ultra. Samsung guarantees four OS updates and five years of security patches, with Android 17 arriving as the final major update and security patches extending through 2028. At current discounted prices, the Galaxy S23 Ultra offers a unique combination of the S Pen, 10x optical zoom, and flagship power that no current Samsung phone replicates.

Frequently asked questions
Is the Samsung Galaxy S23 Ultra still worth buying in 2026?
Absolutely. The Galaxy S23 Ultra remains one of the most capable Android phones available. The Snapdragon 8 Gen 2 still delivers flagship performance, the 200MP camera with 10x optical zoom outreaches even the newer S24 Ultra, and the built-in S Pen is a feature Samsung has since removed from the S25 Ultra. It will receive Android 17 and security patches through 2028, making it a phone you can confidently use for years to come at today's reduced prices.
How does the Samsung Galaxy S23 Ultra compare to the Galaxy S24 Ultra?
The S24 Ultra upgrades to the Snapdragon 8 Gen 3, a brighter 2,600-nit display, a titanium frame, and Galaxy AI features. However, it trades the S23 Ultra's 10x optical zoom for a 5x lens, which is a downgrade for telephoto photography. The S23 Ultra retains the S Pen and offers very similar core performance at a significantly lower price. For photography enthusiasts who value zoom range, the S23 Ultra is arguably the better choice.
Does the Samsung Galaxy S23 Ultra have an S Pen?
Yes, the Galaxy S23 Ultra includes a built-in S Pen stylus with Bluetooth connectivity, allowing you to take handwritten notes, sketch, annotate documents, and use air gestures to control the phone remotely. This is noteworthy because Samsung removed the S Pen from the Galaxy S25 Ultra, making the S23 Ultra and S24 Ultra the last flagship Samsung phones to include it.
How good is the Samsung Galaxy S23 Ultra camera?
The camera system is exceptional. The 200MP main sensor captures extraordinary detail, enabling massive crops without quality loss. The 10x optical zoom telephoto is outstanding for distant subjects and is a feature the newer S24 Ultra lacks. The 3x telephoto handles portrait-range shots, and the 12MP ultrawide covers landscapes. Night photography is excellent across all lenses, and 8K video recording is supported.
How long will the Samsung Galaxy S23 Ultra receive software updates?
Samsung has committed to four years of major Android OS updates and five years of security patches. The Galaxy S23 Ultra launched with Android 13 and has received Android 14, 15, and 16. Android 17, expected in late 2026 or early 2027, will be its final major update. Security patches will continue through early 2028, ensuring the phone stays protected for several more years.
Does the Samsung Galaxy S23 Ultra have good battery life?
Yes, the 5,000mAh battery combined with the efficient Snapdragon 8 Gen 2 chip delivers excellent battery life, typically lasting a full day of heavy use including camera work, gaming, and streaming. It supports 45W wired fast charging, 15W wireless charging, and 4.5W reverse wireless charging. A full wired charge takes just under an hour.
Should I get the Samsung Galaxy S23 Ultra or the Galaxy S23?
It depends on your priorities. The S23 Ultra offers a 200MP camera with 10x optical zoom, a 6.8-inch display, S Pen, and a 5,000mAh battery — ideal for photography and productivity. The S23+ sits between the two with a 6.6-inch display, 50MP main camera with 3x optical zoom, a 4,700mAh battery, and 45W fast charging at a lower price. If you don't need the zoom range or S Pen, the S23+ delivers a very similar flagship experience for less. Compare Samsung Galaxy S23+ deals.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
