Samsung Galaxy S25 Ultra Review: Is This the Best Android Phone You Can Buy in 2026?

INTRODUCTION

The Samsung Galaxy S25 Ultra is here and it comes packed with the kind of flagship credentials that Samsung fans have come to expect from the Ultra series. A stunning 6.9 inch QHD+ Dynamic AMOLED display, a powerful Snapdragon 8 Elite chip built specifically for Galaxy devices, a 200MP main camera that keeps raising the bar for smartphone photography and a suite of Galaxy AI features designed to make the phone feel genuinely intelligent rather than just technically impressive.

But here is the honest truth that every review needs to address upfront. The Samsung Galaxy S25 Ultra is not a reinvention. It is a refinement. A very good one in several important areas but still a refinement. If you are upgrading from a Galaxy S22 Ultra or older this phone will feel like a massive leap forward in every single category. If you upgraded last year from the S24 Ultra you will notice the improvements are real but measured.

This complete Samsung Galaxy S25 Ultra review covers everything: design and build quality, display performance, camera system and photo quality, battery life and charging speeds, the Snapdragon 8 Elite performance, Galaxy AI and One UI 7 software, the S Pen changes, pricing and value and who should actually buy this phone. Let us get into it.

Design and Build Quality: Subtle Changes That Actually Matter

Pick up the Samsung Galaxy S25 Ultra for the first time and your immediate reaction will probably be that it looks very similar to the previous S24 Ultra. And you would be right in a broad sense. Same large premium titanium frame, same quad camera bump on the back, same S Pen slot along the bottom edge, same general dimensions.

But spend more than five minutes with it and the differences become clear. Samsung has rounded off the previously sharp almost rectangular corners of the Ultra design giving the phone a softer more unified appearance that aligns it more closely with the broader Galaxy design language. The bezels are marginally thinner than before squeezing a tiny bit more screen space out of the same body. The phone is also slightly lighter at 218 grams compared to the S24 Ultra which weighed 232 grams and marginally thinner at 8.2mm.

The titanium frame is excellent. It feels cold and premium in the hand in a way that plastic flagships simply cannot replicate and it is noticeably more rigid than earlier aluminum frame designs. The back is covered in Corning Gorilla Armor 2 glass which has an anti reflective coating that does a genuinely impressive job of reducing glare in bright outdoor conditions. The phone is rated IP68 for water and dust resistance meaning it can survive submersion in 1.5 metres of water for 30 minutes.

One design element that has attracted attention is the floating camera rings on the back panel. These slightly raised camera module rings are intentional and Samsung calls them a design statement about the power of the camera system. In practice they do collect pocket lint with remarkable efficiency but the aesthetic is undeniably distinctive.

Overall the Galaxy S25 Ultra design is a mature and premium package. It is not dramatic but it does not need to be. Everything about it communicates that this is a serious flagship device built to last.

Display: Samsung Maintains Its Crown

No smartphone manufacturer makes displays quite like Samsung and the Galaxy S25 Ultra display is yet more proof of that dominance. The 6.9 inch QHD+ Dynamic AMOLED 2X panel is absolutely gorgeous in everyday use. Colors are rich and accurate without being oversaturated in the default settings. Blacks are true black thanks to the AMOLED technology. The 120Hz adaptive refresh rate makes every scroll swipe and animation feel silk smooth and the panel drops to lower refresh rates when displaying static content to preserve battery life.

The 2600 nit peak brightness means this screen is genuinely readable even in direct harsh sunlight which is an area where many competitor displays still struggle. Content consumption on this screen whether Netflix video YouTube or gaming is a genuinely premium experience that very few other phones can match.

The Gorilla Armor 2 glass with anti reflective coating is one of the most underappreciated features of this phone. Reflections and glare are dramatically reduced compared to standard glass making it far easier to use outdoors. It does mean the screen looks slightly different than a traditional high gloss smartphone display when viewed at certain angles but the tradeoff in outdoor usability is very much worth it.

Samsung offers three resolution settings. The default is FHD+ which balances visual quality with battery efficiency. QHD+ delivers the sharpest possible image but does consume more battery. For most users FHD+ is the sweet spot but the option to push to QHD+ when watching premium content is a welcome flexibility. Read more about how the S25 Ultra display compares at

Performance: The Snapdragon 8 Elite Is an Absolute Beast

The Snapdragon 8 Elite for Galaxy is not just the standard Snapdragon 8 Elite that appears in other 2025 flagship Android phones. It is a custom variant that Qualcomm and Samsung have jointly tuned specifically for Galaxy devices. The result is a processor that is not only the fastest chip in any Android phone in 2026 but also one of the most thermally efficient.

In everyday use this phone is remarkably fast. Apps open instantly. Multitasking across several demanding applications at once is handled without hesitation. Animations throughout One UI 7 feel genuinely snappy and there is no lag anywhere in the interface. For anyone coming from an iPhone who has found Android transitions to feel slow the S25 Ultra on One UI 7 will genuinely surprise you.

Gaming performance is flawless. Demanding 3D titles run at maximum settings with no frame drops and the phone stays impressively cool even during extended gaming sessions. This thermal management improvement comes from a redesigned vapor chamber that is 40% larger than the one in the S24 Ultra combined with new thermal interface material. In benchmark and thermal testing the Galaxy S25 Ultra ran cooler than other Snapdragon 8 Elite devices including its own predecessor which is a notable real world achievement not just a spec sheet claim.

The 12GB of RAM paired with One UI 7’s improved memory management means app switching is fast and apps stay resident in memory far longer before needing to reload. Multitasking with Samsung’s split screen features feels genuinely productive in a way that few phones can claim.

Camera System: A 200MP Quad Setup That Raises the Bar

The Samsung Galaxy S25 Ultra camera system is one of the most talked about aspects of the phone and for good reason. Four cameras cover virtually every photographic scenario you can imagine and the new 50MP ultra wide lens is a significant upgrade over the 12MP ultra wide found in the S24 Ultra.

The Main 200MP Wide Camera

The 200MP f/1.7 main camera with optical image stabilisation is the headline act and it delivers genuinely outstanding results. Photos are sharp well exposed and vibrant without tipping into the overprocessed territory that has plagued some Android flagships in the past. Autofocus is fast and accurate even when tracking fast moving subjects like children or pets in unpredictable situations. Low light performance is excellent with the AI powered Night Mode preserving genuine detail rather than simply brightening a blurry mess. Consumer Reports testing confirmed the S25 Ultra has one of the strongest camera systems they have ever tested noting excellent color quality exposure levels sharpness and low image noise across all lighting conditions.

The New 50MP Ultra Wide Camera

This is the most meaningful hardware upgrade in the S25 Ultra camera system. The previous 12MP ultra wide has been replaced with a new 50MP sensor with a 120 degree field of view giving you dramatically more resolution when shooting wide angle scenes landscapes architecture and group shots. The detail retention in ultra wide shots is now genuinely comparable to the main camera rather than being a clearly inferior secondary option. Macro photography using the ultra wide lens is also excellent with crisp close up detail that rivals dedicated macro cameras.

Telephoto System

The dual telephoto setup gives you 3x optical zoom via the 10MP lens and 5x optical zoom via the 50MP lens covering a wide range of zoom scenarios from portrait photography through to wildlife and sports shooting. AI Zoom extends digital zoom beyond these optical lengths with impressive detail preservation up to around 10x before quality noticeably drops. The Space Zoom feature can push to 100x in extreme situations although results at that magnification are more novelty than practical.

Video Quality

Video quality on the Samsung S25 Ultra is excellent across all lighting conditions. Night Video mode with Audio Eraser is a genuinely useful feature that simultaneously improves low light exposure while allowing you to isolate and reduce specific ambient sounds from your footage. While iPhones still have a slight edge in certain cinematic video scenarios Samsung has narrowed that gap considerably to the point where for the vast majority of users the S25 Ultra’s video quality is more than good enough to replace a dedicated camera for everyday content creation.

Battery Life and Charging: Good but Not Groundbreaking

The Samsung Galaxy S25 Ultra battery is a 5000mAh cell which is the same capacity as the S24 Ultra. On paper that sounds like no progress at all but in real world usage the combination of the more efficient Snapdragon 8 Elite processor and One UI 7’s battery optimisations delivers a noticeable improvement in endurance.

Samsung rates the S25 Ultra for up to 31 hours of video playback which is one hour more than the S24 Ultra and the longest video playback time of any Ultra in Samsung’s history. In practical daily use most users will comfortably get through a full day of moderate to heavy usage including social media browsing navigation video streaming email and calls. Heavy users pushing intensive gaming or 4K video recording for extended periods will likely want to top up before the end of the day. The phone consistently lasts a full day and reliably gets through a day and a half with lighter usage.

Charging remains at 45W for wired charging which is functional but lags behind some competitors offering 80W or even 100W charging speeds in similarly priced devices. A full charge from empty takes approximately 65 to 70 minutes. The phone supports the new Qi2 wireless charging standard for up to 15W wireless speeds and also supports reverse wireless charging for accessories like Galaxy Buds or a Galaxy Watch. Given the phone’s premium price point the absence of faster wired charging is a legitimate criticism that Samsung will hopefully address in the next generation.

Galaxy AI and One UI 7: Smart Features That Actually Work

Galaxy AI is Samsung’s most prominent selling point for the S25 Ultra and after months of real world use the verdict is nuanced. When it works it is genuinely impressive. When it feels superfluous it can seem like AI for AI’s sake rather than AI that solves real problems.

The features that genuinely deliver value include the following.

Circle to Search with Google is one of the most useful AI features on any Android phone. Draw a circle around anything on your screen and Google searches it instantly. Product labels street signs plants objects in photos and text in foreign languages all become immediately searchable without ever leaving the app you are in. Once you start using it you wonder how you survived without it.

Live Translate for calls translates phone conversations in real time allowing you to have a conversation with someone speaking a completely different language without either party needing a translation app. For travellers and international business users this is genuinely transformative.

Transcript Assist in the Voice Recorder app records audio identifies different speakers and provides an AI summary of the key points discussed. For anyone who takes meetings on their phone or records interviews this feature alone saves significant time.

Photo Assist allows you to remove objects from photos add elements and use generative fill to replace areas of an image seamlessly all directly on the device without a computer. The results are genuinely impressive for a mobile AI editor.

Now Brief delivers personalised daily summaries based on your calendar weather and travel information directly from the lock screen. Some users find it invaluable while others find it more noise than signal and disable it within the first week.

Audio Eraser in the camera allows you to isolate and reduce specific sounds in videos including voices music background noise crowds wind and nature sounds. The feature works better than you might expect from a first generation AI audio tool and is genuinely useful for anyone who shoots a lot of video content.

One UI 7 on top of Android 15 is the most refined version of Samsung’s software to date. Animations are snappy the settings menu is cleaner and better organised and the overall visual design has a consistency and polish that previous versions sometimes lacked. The voice controlled settings search feature that lets you say something like “make the text more visible” and have the phone navigate directly to the relevant setting is a small but genuinely useful accessibility and usability improvement.

S Pen: Still Great but the Bluetooth Removal Stings

The Samsung Galaxy S25 Ultra S Pen remains one of the most distinctive and genuinely useful features that separates the Ultra line from every other flagship smartphone on the market. The writing experience is precise and natural feeling with a level of accuracy that makes handwriting notes sketching and annotating documents genuinely practical rather than just a gimmick.

Drawing Assist powered by Galaxy AI lets you sketch a rough drawing on screen and have the AI transform it into a polished generated image. The results are surprisingly good and the feature has real creative utility beyond just being a demonstration of what the hardware can do.

However there is a significant and controversial change in this generation that many dedicated S Pen users will dislike. Samsung removed Bluetooth connectivity from the S Pen along with its internal battery. This means the Air Actions feature is gone. You can no longer use the S Pen as a remote shutter for photos control presentations wirelessly or swipe through your gallery using stylus gestures from a distance. Samsung’s reasoning is that fewer than one percent of users ever used these features. That may well be statistically true but for the users who relied on the remote shutter for tripod photography or the presentation controls for professional presentations the removal feels like a genuine step backward in capability.

An additional frustration is that the internal charging coils for a Bluetooth S Pen remain inside the phone’s hardware which has sparked speculation that Samsung may introduce a Bluetooth S Pen as a paid accessory in a future update. The S24 Ultra’s S Pen also does not fully fit the S25 Ultra’s slot which adds an unnecessary compatibility inconvenience.

For users who never used Air Actions the S Pen change is completely invisible in day to day use and the stylus experience for writing and drawing is as good as ever. For dedicated power users who built Bluetooth functionality into their workflows it is a meaningful downgrade worth factoring into a purchasing decision.

Samsung Galaxy S25 Ultra vs S24 Ultra: Is the Upgrade Worth It?

This is the question on the mind of every current S24 Ultra owner. The honest answer is that the Samsung Galaxy S25 Ultra upgrade from S24 Ultra is worthwhile if you value any of the following specific improvements but is not a must do upgrade if your S24 Ultra is performing well and you are not drawn to a specific new feature.

Upgrade if: You want significantly better ultra wide camera performance. The jump from 12MP to 50MP ultra wide is the single most meaningful camera hardware upgrade in this generation and it is genuinely substantial in real world photos. You also want cooler running sustained performance from a more efficient processor. You will notice improved thermal performance during gaming and intensive multitasking. The lighter weight and refined rounded corner design may also appeal if you found the S24 Ultra’s sharp edges uncomfortable during extended use.

Stay on S24 Ultra if: You heavily use the S Pen’s Bluetooth Air Actions features, You want 5G mmWave support as a priority. You find 45W charging already adequate for your lifestyle,You are happy with your current camera system. The S24 Ultra is still an excellent phone that will continue receiving software and Galaxy AI updates and there is no urgent reason to upgrade unless one of the above improvements directly addresses a limitation you experience today.

Samsung Galaxy S25 Ultra Price: Is It Worth the Money?

The Samsung Galaxy S25 Ultra price starts at $1299 for the 256GB base model which is the same starting price as the S24 Ultra. The 512GB variant and the 1TB top tier model carry premium prices above that entry point. On pure sticker price this is a premium investment. However Samsung consistently runs significant promotional deals including trade in credits pre order discounts and carrier bundled offers that can bring the effective cost down dramatically. Review sources have noted that early buyers with trade ins were able to get the phone for as little as $399 effective after trade in credits.

The value proposition of the S25 Ultra is strengthened considerably by Samsung’s 7 year software update commitment. That means this phone will receive major Android OS updates through 2032 which is an extraordinary support lifespan for an Android device and one that rivals Apple’s iPhone update longevity. Amortised over seven years the $1299 starting price becomes considerably more defensible.
