Samsung Galaxy S26 Ultra Review Camera Battery AI Features and UK Price
Samsung Galaxy S26 Ultra review covering UK price, camera, battery, AI features, pros, cons and buying advice.
The Samsung Galaxy S26 Ultra is Samsung's premium flagship phone for users who want a powerful camera system, a large high-end display, Galaxy AI features, S Pen productivity, strong performance and long-term Android value. In this Samsung Galaxy S26 Ultra review, we look at its design, display, camera, battery life, performance, AI features, UK price, pros and cons, and whether it is worth buying over the Galaxy S25 Ultra, iPhone alternatives and other Android flagships.
For UK buyers, the S26 Ultra is not just another expensive smartphone. It is a serious upgrade option for business users, content creators, Samsung fans, mobile photographers and anyone who wants one of the most complete Android phones available. However, because the price is high, choosing the right storage size and buying option matters.
Samsung officially announced the Galaxy S26 series on 25 February 2026, with UK availability from 11 March 2026. Samsung's UK pages position the S26 Ultra as an AI-focused flagship with Galaxy AI, an advanced display, strong camera features and a refined premium design.
Quick Verdict: Is the Samsung Galaxy S26 Ultra Worth Buying?
Yes, the Samsung Galaxy S26 Ultra is worth buying if you want Samsung's best flagship experience, a premium camera system, Galaxy AI tools, S Pen support, a large display and strong long-term value. However, it is not the best choice for budget buyers, compact phone users or anyone who already owns a recent Ultra model and does not need the latest AI and camera improvements.
UK buyers who are already planning to upgrade can check the latest Samsung Galaxy S26 Ultra UK availability, storage options and deals on the Zextons Samsung product page.
The Samsung Galaxy S26 Ultra is one of the strongest Android flagship phones for UK buyers who want a premium camera phone, a large display, S Pen productivity and practical Galaxy AI features. It is expensive, but it makes sense for users who will fully use its camera, AI tools, performance and productivity features. For most buyers, the 512GB model offers a better long-term choice than the base 256GB model.
Samsung Galaxy S26 Ultra Pros and Cons
Samsung Galaxy S26 Ultra Specs at a Glance
Samsung UK's official specs page lists the Galaxy S26 Ultra with a 5000mAh typical battery, up to 31 hours video playback, 214g weight, 7.9mm thickness, Samsung DeX support, SmartThings support and security update support until 28 February 2033.
Design and Build Quality
The Samsung Galaxy S26 Ultra keeps the premium Ultra identity but refines it for daily use. It is still a large phone, but the slim 7.9mm body and 214g weight help it feel more manageable than many users may expect from a flagship with a 6.9-inch display. For users who want a compact phone, this is still not the best choice. However, for people who like big screens, multitasking, gaming, reading and S Pen use, the size makes sense.
The S26 Ultra is designed for buyers who want a serious flagship rather than a simple everyday phone. It feels more like a productivity device, camera phone and entertainment screen in one package. Therefore, it works especially well for business users, content creators, Samsung Note fans and people who use their phone heavily throughout the day.
Is the Samsung S26 Ultra too big?
The Samsung S26 Ultra is large, but that is part of its appeal. The big display is useful for watching videos, editing photos, reading documents, gaming, using split-screen apps and taking handwritten notes with the S Pen. However, if you prefer one-handed use or smaller pockets, the standard Galaxy S26 or S26 Plus may feel more comfortable.
Design verdict
The design is premium, practical and clearly built for power users. It may not be the most compact phone, but it gives you the screen size and productivity space that make the Ultra model different from normal flagship phones.
Display Review: Big Screen, Smooth Scrolling and Privacy Features
The display is one of the strongest reasons to consider the Samsung Galaxy S26 Ultra. Samsung is known for excellent screens, and the S26 Ultra continues that reputation with a large, smooth and bright display designed for video, gaming, multitasking and reading.
Samsung UK describes the S26 Ultra as having its "most advanced display yet" and highlights the built-in Privacy Display as one of the phone's major new features.
Screen quality
The large display makes everyday tasks feel easier. For example, browsing, watching YouTube, reading emails, editing photos, checking product listings and using maps all benefit from the bigger screen. In addition, the high refresh rate makes scrolling feel smooth, which helps when switching between apps or moving through long webpages.
Privacy Display
The Privacy Display is one of the most interesting features of the S26 Ultra. It is designed to make the screen harder to view from side angles, which can help protect private information when you are using the phone in public places such as trains, cafés, airports or offices.
This is useful for:
Banking apps
Private messages
Work emails
Business documents
Notifications
Password screens
Sensitive personal data
However, privacy features can sometimes affect viewing angles or display comfort. Therefore, users who often share their screen with someone beside them may prefer to adjust the feature depending on the situation.
Display verdict
The Samsung S26 Ultra display is excellent for entertainment, productivity and daily use. The Privacy Display gives it a unique advantage for business users and commuters, while the large screen makes it one of the best Samsung phones for multitasking.
Samsung Galaxy S26 Ultra Camera Review
The camera is one of the biggest reasons people search for a Samsung Galaxy S26 Ultra review. Samsung's Ultra phones are known for high-resolution sensors, strong zoom, bright images and advanced camera software. The S26 Ultra continues that focus with a camera system designed for photos, videos, social content and professional-style mobile creativity.
Samsung UK describes the S26 Ultra as having its "brightest camera system yet," while Samsung's product page also connects the camera experience with Galaxy AI and image enhancement.
Main camera quality
The Samsung S26 Ultra is built for users who want sharp, detailed and high-quality images. It is especially suitable for people who take photos of products, travel, family moments, events, food, landscapes and social media content.
For Zextons readers, this matters because the camera is not only for casual photos. It is also useful for content creators, online sellers, influencers and business users who need high-quality images without always carrying a separate camera.
Zoom and telephoto performance
Samsung Ultra phones are famous for zoom, and this is one of the main reasons to choose the Ultra instead of the standard Galaxy S26 or S26 Plus. If you often take photos at events, concerts, travel locations or outdoor scenes, the zoom system gives you more flexibility.
The Ultra model is also a better choice for users who want a camera phone that can handle different distances, not just normal everyday shots.
Low-light photography
Low-light camera performance is important because many people take photos indoors, at night, in restaurants, at events or during travel. The S26 Ultra is designed to use advanced camera processing and AI support to improve image quality in difficult lighting.
Video recording
The S26 Ultra is also a strong option for video creators. If you record product videos, social media clips, YouTube content, TikTok videos or family videos, the combination of a large display, strong camera system and high-end performance makes it a practical creator phone.
Camera verdict
The Samsung Galaxy S26 Ultra is one of the best Samsung camera phones for users who want detailed photos, strong zoom, good low-light performance and flexible video features. If the camera is your main reason for upgrading, the S26 Ultra is easier to justify than the standard S26 models.
Performance and Gaming
Performance is another major strength of the Samsung Galaxy S26 Ultra. Samsung UK says the phone is powered by the Snapdragon 8 Elite Gen 5 for Galaxy and describes it as engineered for Galaxy AI, heavy multitasking and amplified gaming performance.
Daily performance
For normal daily use, the S26 Ultra should feel extremely fast. Apps open quickly, scrolling feels smooth, and multitasking is easier because of the large display and powerful hardware. If you use your phone for emails, browsing, social media, shopping, content creation, video calls and productivity apps, the S26 Ultra has more than enough power.
Gaming performance
The Samsung S26 Ultra is also a strong gaming phone. The large screen, flagship processor and smooth refresh rate make it suitable for demanding mobile games. In addition, Samsung UK highlights the phone's large vapour chamber and gaming-focused performance, which is important for users who play longer sessions.
Multitasking and productivity
The Ultra is not only about raw speed. It is also a productivity phone. The large display, S Pen, Samsung DeX support and Galaxy AI tools make it more useful for work than many standard smartphones.
Performance verdict
The Samsung Galaxy S26 Ultra is ideal for users who want fast performance, smooth gaming, strong multitasking and future-ready Android power. Most users will not push it to its limits, but power users will appreciate the extra performance.
Galaxy AI and Software Experience
Galaxy AI is one of the biggest themes of the Samsung Galaxy S26 Ultra. Samsung is positioning the S26 series heavily around AI, daily assistance, smart tools and privacy-focused features.
Useful Galaxy AI features
Galaxy AI can help with everyday tasks such as:
Writing assistance
Summarising notes
Translating conversations
Editing photos
Searching content on screen
Improving productivity
Helping with communication
Making repetitive phone tasks easier
For many users, the best AI features are not the flashy ones. They are the small tools that save time every day, such as summarising text, improving writing, editing images and helping you find information faster.
AI for business users
The Samsung S26 Ultra is especially useful for business users because AI tools can help with emails, notes, meetings, translations and document work. Combined with the S Pen and Samsung DeX, the S26 Ultra becomes more than a normal smartphone.
One UI and updates
Samsung's One UI remains one of the most complete Android software experiences. It offers strong customisation, Samsung ecosystem features, multitasking tools and long-term support. Samsung UK's specs page lists security update support until 28 February 2033, which adds long-term value for buyers who keep phones for several years.
Recent reports also say Samsung has started rolling out the One UI 9 beta for Galaxy S26 series users in countries including the UK, with updates to Quick Panel, Samsung Notes, accessibility and security features.
Galaxy AI verdict
Galaxy AI gives the S26 Ultra a stronger productivity angle. It is not just a camera phone or gaming phone. It is also a smart daily assistant for users who want to save time and work more efficiently.
S Pen and Productivity
The built-in S Pen remains one of the biggest reasons to choose the Samsung Galaxy S26 Ultra over other flagship phones. While many premium phones offer great cameras and fast processors, very few include a built-in stylus.
What can you use the S Pen for?
The S Pen is useful for:
Taking quick notes
Signing documents
Editing images
Sketching ideas
Marking screenshots
Writing lists
Business planning
Studying
Precise selections on screen
Who benefits most from the S Pen?
The S Pen is especially useful for business users, students, designers, content creators and anyone who still likes writing or marking things manually. If you loved the old Galaxy Note series, the S26 Ultra is the closest modern version of that experience.
S Pen verdict
The S Pen may not matter to every buyer, but for the right user, it is a major advantage. If you use your phone for work, documents, planning or creative tasks, the S Pen helps the S26 Ultra stand out from iPhone, Pixel and OnePlus alternatives.
Battery Life and Charging
Battery life is good, but it is not the strongest reason to buy the Samsung Galaxy S26 Ultra. Samsung UK lists the S26 Ultra with a 5000mAh typical battery and up to 31 hours video playback.
How long does the Samsung S26 Ultra battery last?
For most users, the S26 Ultra should comfortably last a full working day. However, battery life depends heavily on how you use it. Gaming, 5G, navigation, video recording, high brightness and heavy camera use can drain the battery faster.
Is 5000mAh enough?
A 5000mAh battery is still strong, but some rival Android phones now offer larger batteries. Therefore, if your main priority is two-day battery life, the S26 Ultra may not be the absolute best choice. However, if you want a balance of camera, performance, AI, display and productivity, the battery should be enough for most daily users.
Charging
The S26 Ultra supports fast charging and wireless charging options, but Samsung notes that the actual adapter or charger may need to be purchased separately.
Battery verdict
The Samsung Galaxy S26 Ultra battery is good enough for most users, but heavy users may still need a top-up by the evening. It is a strong all-round flagship, but not necessarily the battery-life champion.

Best storage recommendation
