The Samsung Galaxy S23 Ultra remains an unusually capable premium phone in 2026. Its Snapdragon 8 Gen 2 for Galaxy processor, built-in S Pen, long-range optical zoom, and bright 6.8-inch display still cover needs that many newer phones do not combine in one device. Age has also made it substantially more affordable, especially through refurbished and carefully inspected used listings. This review examines its specifications, realistic 2026 pricing, camera and battery experience, recurring feedback from reviewers and owners, software-support outlook, drawbacks, buying timing, and alternatives. The analysis is based on published specifications, long-term expert coverage, and recurring community reports rather than first-hand laboratory testing.
Quick answer: Yes, if you want excellent zoom, an integrated stylus, a premium display, and strong performance at a reduced price. No, if you need a compact phone, guaranteed support far beyond 2028, or consistently fast photography of moving subjects.
1.1 Core Specs
Samsung designed the S23 Ultra as an all-in-one flagship rather than a minimalist handset. The defining hardware includes two optical telephoto cameras, a high-resolution main sensor, integrated S Pen storage, and a large adaptive-refresh display. Storage configurations and available memory can vary by market.

2. Price & Value Analysis
2.1 Current Pricing
The S23 Ultra launched at $1,199.99 in the United States for the base configuration. In 2026, buyers should judge it as a discounted former flagship, not as a current full-price device. A sensible target is roughly $350-$500 for a reputable refurbished unit, with higher-capacity models and exceptional-condition examples sometimes costing more. Sealed old stock may approach $600-$750, but value becomes less persuasive at that level because newer phones offer longer remaining support.
| Condition | Suggested Range | Value | Check Before Buying |
|---|---|---|---|
| Used | $350-$450 | Best bargain Winner | Battery, screen, S Pen, cameras |
| Refurbished | $400-$550 | Strong with warranty | Return policy and grade |
| New old stock | $600-$750 | Only at a deep discount | Activation terms and warranty |
2.2 Is It Worth Buying?
At around $500 or less, the S23 Ultra is still a compelling value for buyers who will use its zoom cameras or S Pen. Performance remains fast enough for demanding apps, multitasking, video editing, and high-quality games. Its remaining weakness is longevity: security support is expected to extend into 2028, leaving less runway than newer Samsung flagships. Condition also matters more than raw price.

3. Real User Experience
3.1 Video Reviews Summary
Long-term video coverage provides a more useful perspective than launch-day excitement. Marques Brownlee highlighted the S23 Ultra's polished flagship experience, powerful cameras, strong battery endurance, and familiar design, while also noting that it was an iterative update rather than a radical redesign. Mrwhosetheboss emphasized the unusually flexible camera system and improved efficiency, but the phone's large dimensions and premium launch price remained meaningful compromises.
Later retrospective reviews generally reach a similar conclusion: the processor has aged well, the screen still looks excellent, and the 10x optical camera remains distinctive. However, newer models deliver longer support and additional software features. Some camera processing changes can also arrive through updates, so buyers should assess current sample images rather than assuming the launch appearance is unchanged.
3.2 What Reddit Users Are Saying
Recurring owner discussions tend to fall into three patterns. In long-term battery threads, many users report comfortable all-day use, while heavy gaming, navigation, weak cellular signal, and maximum brightness can shorten runtime substantially. Camera discussions praise distant subjects, travel flexibility, and daylight detail, but frequently mention shutter lag or motion blur when photographing children and pets indoors.
Upgrade threads often argue that the S23 Ultra remains fast enough to keep, especially for owners satisfied with its cameras and S Pen. Buying-advice threads are more cautious: owners commonly recommend checking for screen burn-in, frame damage, charging-port wear, lens problems, missing S Pens, and carrier locks. These are anecdotal patterns rather than controlled findings, but they identify sensible inspection priorities.
3.3 Key User Feedback Themes
3.4 Expert Opinion
The strongest reason to choose this phone in 2026 is not benchmark leadership; it is feature density at a reduced price. Few discounted phones combine a built-in stylus, desktop-style DeX support, QHD+ display, 10x optical camera, IP68 protection, and mature software. The purchase makes the most sense below $500 with a return window. Above roughly $650, a newer model with longer support is usually the safer long-term investment.
4. Performance & Everyday Use
The Snapdragon 8 Gen 2 for Galaxy remains responsive for ordinary use and demanding workloads. Apps open quickly, multitasking benefits from the large display, and the efficient processor avoids the severe heat and battery concerns associated with some earlier flagship generations. Sustained gaming can still warm the frame and reduce performance, but that behavior is normal for a thin, passively cooled phone.
The display is a daily highlight: text is sharp, outdoor visibility is strong, and adaptive refresh makes scrolling fluid. The curved edges are less severe than on older Ultra phones but can complicate screen-protector installation. Battery life should cover a normal day for many users, although a multi-year-old battery may perform very differently. The 45W charging ceiling is adequate rather than class-leading, and reaching it requires a compatible charger that is not included.

6. Best Time to Buy
6.1 Historical Price Trends
Older Galaxy Ultra phones usually lose value after each new Galaxy S generation, then settle into a slower decline. By 2026, condition, storage, color, warranty, and carrier status create more price variation than small seasonal changes. A clean refurbished unit with a meaningful warranty may be worth paying $40-$75 more for than an unknown marketplace device. Use the price history rather than treating a crossed-out list price as proof of a bargain.
6.2 Upcoming Sales Events
Prime Day-style promotions, Black Friday, Cyber Monday, year-end clearance, and new Galaxy launch periods are the most likely discount windows. Refurbishers may also run smaller promotions around back-to-school season. Because inventory is aging, waiting only makes sense if your preferred storage and condition remain widely available. Set a price alert with ShopFox and choose a target based on actual condition rather than headline discount percentage.
7. Top Alternatives
Three alternatives deserve consideration. The Galaxy S24 Ultra offers a flatter display, longer software support, and a newer processor, making it the logical upgrade when the price gap is modest. The Google Pixel 8 Pro prioritizes straightforward photography and Google's software experience, but it lacks an integrated stylus and true 10x optical camera. The iPhone 15 Pro Max is a strong option for buyers invested in Apple's ecosystem, although its interface, accessory compatibility, and camera approach differ significantly.
| Feature | Galaxy S23 Ultra | Galaxy S24 Ultra | Pixel 8 Pro |
|---|---|---|---|
| Best for | Discounted zoom and S Pen Winner | Long-term ownership | Point-and-shoot photos |
| Telephoto | 3x and 10x optical Winner | 3x and 5x optical | 5x optical |
| Stylus | Integrated S Pen | Integrated S Pen | None |
| Support outlook | Shortest remaining period | Longest Winner | Long-term support |

Frequently Asked Questions
Is the Samsung Galaxy S23 Ultra still worth buying in 2026?
Yes, provided the price and condition are right. It remains fast, has an excellent display, includes the S Pen, and offers unusually flexible telephoto cameras. A refurbished price near $400-$500 is attractive. The main concern is its shorter remaining support period compared with newer Galaxy phones. Buyers planning to keep a device for four or more additional years may receive better value from a newer model.
How long will the Galaxy S23 Ultra receive updates?
Samsung promised four generations of Android upgrades and five years of security updates for the S23 series. Because the phone launched in 2023 with Android 13, its final major operating-system generation should follow that four-upgrade commitment, while security coverage is expected into 2028. Exact rollout timing can vary by country, carrier, and device variant. This remaining window should be considered when comparing it with newer models offering longer policies.
How good is the Galaxy S23 Ultra battery life?
The 5,000mAh battery and efficient Snapdragon processor can provide a full day for many users, but workload and battery health matter. Gaming, navigation, mobile hotspot use, weak signal, high brightness, and extensive camera use reduce endurance. A used phone may have significantly less capacity than a new unit. Ask for battery information when available and buy from a seller with a practical return policy if endurance is important.
Is the 200MP camera actually useful?
The 200MP mode can preserve extra detail in bright conditions and provides cropping flexibility, but it is not the best default for every scene. Standard photo modes process files faster, consume less storage, and often handle challenging light more reliably. The broader advantage is the complete camera system: capable main and ultrawide cameras plus dedicated 3x and 10x lenses. Indoor moving subjects remain a potential weakness because motion blur can occur.
Does the Galaxy S23 Ultra support 45W charging?
Yes, it supports wired charging up to 45W with compatible equipment, as well as 15W wireless charging and reverse wireless charging. Samsung does not include a power adapter in the standard box, so buyers may need an appropriate USB-C charger and cable. Peak wattage is not maintained for the entire session, and temperature affects charging speed. Its charging system is adequate but slower than several competing Android flagships.
Is the Galaxy S23 Ultra too big for everyday use?
That depends on hand size and habits, but the 6.8-inch display, 234g weight, and angular corners make it noticeably large. It is excellent for reading, handwriting, split-screen work, maps, and video, yet one-handed use can be uncomfortable. A protective case adds further width and weight. Buyers moving from a compact phone should handle a similarly sized device before ordering rather than relying only on diagonal screen measurements.
What should I inspect when buying a used S23 Ultra?
Check the AMOLED panel for burn-in, dead pixels, scratches, and touch problems. Confirm that every rear camera focuses correctly, the S Pen is included and connects, the USB-C port works, speakers sound clear, and biometric unlocking functions. Verify storage capacity, carrier-unlocked status, device identifiers, and return terms. Ask whether the phone has been repaired, and remember that water resistance cannot be guaranteed after damage or unauthorized servicing.
Should I buy the S23 Ultra or pay more for the S24 Ultra?
Choose the S23 Ultra when savings are substantial and 10x optical zoom matters. Choose the S24 Ultra for its flatter display, newer processor, much longer support commitment, and stronger long-term resale outlook. A small price difference favors the S24 Ultra; a gap of several hundred dollars makes the S23 Ultra more appealing. Compare equivalent storage, condition, warranty, and carrier status rather than comparing a used S23 Ultra with a brand-new successor.
Conclusion
The Samsung Galaxy S23 Ultra remains one of the most complete former flagships available in 2026. Its bright display, responsive processor, integrated stylus, DeX support, and genuine 10x optical camera preserve advantages that many current midrange phones cannot match. Its size, motion-photo inconsistency, aging batteries, and finite update runway require a more careful purchase, however. Aim for a reputable refurbished example near $500 or less, verify condition and returns, and use ShopFox to compare like-for-like listings before committing.
The Verdict
Buy the Galaxy S23 Ultra if you want flagship performance, long-range zoom, and an integrated S Pen without paying current flagship prices. Skip it if compact size or maximum software longevity is your priority. The strongest value is a warrantied refurbished unit in excellent condition below roughly $500.
