Samsung Galaxy S25 Ultra Review: Photo Quality, Video and Performance

I carried the Galaxy S25 Ultra as my main phone for several weeks, shooting photos in daylight, at dusk and indoors, recording video on walks and at events, and running the apps and games I use every day. The first impression is one of calm confidence: a flat 6.9-inch screen, a titanium frame with softly rounded corners, and a built-in S Pen that is always there when an idea needs a quick note. This is a phone that wants to be the only camera, the only notebook and the only gaming device in your pocket, and for most of that time it succeeds.

If you only need the numbers, the specifications section later in this article lists every figure in one place, from the 200MP main camera to the 5000mAh battery. This article is the lived experience behind those numbers: what the 200MP camera actually does with a busy street scene, how far the zoom stays usable, how long a gaming session stays smooth, and where the phone still asks for a compromise. Readers who are weighing the cheaper large-screen option should also read the Samsung Galaxy S25+ Review: Design, Battery Life and Usability, because the two phones share a chip and much of the same software, and the choice between them comes down to cameras, the S Pen and how much bulk you will accept.

What follows is organised around the three promises in the title. First the cameras, in daylight and at night, with the zoom range tested at every step. Then video, where 8K and 4K at 120fps change what you can capture. Then performance, where the Snapdragon 8 Elite for Galaxy has to prove itself across games, multitasking and long hot days. Along the way I cover the display, the titanium build, battery life, charging, One UI 7 and Galaxy AI, and I finish with the full specifications table, a frank list of pros and cons, and answers to the questions buyers ask most often.

Samsung Galaxy S25 Ultra 200MP camera photo quality in daylight and detail

The main camera is the headline, and in good light it earns that place. The 200MP sensor captures a huge amount of detail, and Samsung’s processing keeps colours vivid without pushing them into cartoon territory most of the time. Skin tones look natural in portraits, green foliage keeps its texture instead of turning into a flat wash, and brickwork, fabric and distant signage all hold up when you pinch to zoom into the frame on the phone itself. The default 12MP pixel-binned output is the sensible choice for most shots, because it balances detail with clean files and fast handling, and it is the mode I left the camera in for day-to-day shooting.

Switching to the full 200MP mode is worth it for landscapes and architecture, where you may want to crop hard later, though files get much larger and processing takes a beat longer. I used it for a wide shot of a market street at midday, then cropped to a single shopfront from the same file and still had a usable image for sharing. That is the real value of the high resolution: not the number on the box, but the freedom to reframe after the moment has passed. The 200MP quad-camera system gives you that freedom across four lenses, not just the main sensor, and the ultrawide and telephoto lenses benefit from the same careful processing.

200MP main camera results in bright light and busy scenes

In bright light the 200MP main camera rewards a steady hand and a little patience. Busy scenes with mixed textures, such as a food market or a crowded plaza, come out with separation between subjects instead of the mushy blending cheaper phones produce. Highlights hold their detail in white walls and bright skies, and shadows keep enough information that a quick edit can lift them without turning the image noisy. That said, very high-contrast scenes can still push the processing into a slightly over-sharpened look at 100 percent zoom, so I keep the full-resolution mode for scenes that deserve it and use the standard mode for everything else.

One habit that improved my results was tapping to set focus and exposure on the subject rather than trusting the automatic choice in every scene. The camera is fast, and the shutter lag is short, but a half-second spent on exposure makes the difference between a good photo and a great one when the light is harsh. The phone also handles backlit portraits well, lifting faces without blowing out the sky behind them, which is exactly the kind of everyday shot that used to need editing. For family photos, street photography and travel snaps, the main camera is the most reliable part of this phone.

50MP ultrawide camera and 50MP 5x telephoto zoom range

The ultrawide camera moved to 50MP on this generation, and the step up is visible in the corners of the frame. Wide shots of buildings and interiors keep their detail at the edges instead of smearing, and the lens distortion is well controlled for a phone camera. I used it for a narrow alley where stepping back was impossible, and for group photos at a table where nobody wanted to squeeze together. The ultrawide also doubles as a capable macro camera, focusing close on flowers, food and small objects with pleasing results.

The 5x telephoto, also 50MP, is the more useful zoom lens for everyday shooting. Portraits at 5x have a pleasing compression, distant subjects stay sharp, and the jump from 1x to 5x feels like a real optical step rather than a digital trick. Between 2x and 3x the phone crops from the main sensor, and results stay good in daylight, though they lose a little of the crispness you get at the native focal lengths. The 10MP 3x telephoto fills that middle gap for portraits and closer subjects, and together the four lenses cover a range that would once have needed a bag full of glass.

How the 5x optical zoom holds up at 10x and 30x in real use

At 10x the S25 Ultra still produces usable photos in good light, with enough detail for social sharing and small prints. The phone blends optical zoom with software processing at this range, and in daylight the results are honest: a distant building, a bird on a wire, a sign across a square all come out readable and reasonably sharp. At 30x the image softens clearly and the software detail work becomes obvious, so I treat 30x as a tool for reading a distant sign or checking a detail, not for photos I plan to keep. The maximum 100x zoom is a party trick more than a photographic tool, fun to try once and easy to forget afterwards.

Stabilisation matters more than the zoom number once you pass 10x, and here the phone does well. Holding it with both hands and bracing my elbows gave me sharper results than shooting one-handed, and the phone’s zoom preview helps you find the subject before you take the shot. In low light the long zoom falls off faster, as it does on every phone, so I keep long zoom shots for daylight and use the main camera after dark. That is a sensible limit to accept, and it matches how I actually use a phone camera.

Night photography and low light photo quality on the Galaxy S25 Ultra

After dark the phone leans on Night mode, and the results are strong for a phone camera. Street scenes keep their colour instead of turning orange or grey, neon signs stay readable, and faces in dim restaurants come out bright enough to share without heavy editing. The phone takes a few seconds to gather light in the darkest scenes, and you need to hold still during that time, but the payoff is a clean image where older phones would have given up. The main camera does the heavy lifting at night, and the ultrawide is usable too, though it shows more noise in the shadows than the main sensor.

One surprise was how well the phone handles mixed indoor lighting, the kind of warm lamps and cool windows that confuse many cameras. White balance stays believable, and skin tones do not drift green or magenta. The night portrait mode separates the subject from the background cleanly, and the blur looks natural rather than painted on. If you photograph concerts, evening markets or city streets after dark, this is where the Ultra earns its price over the smaller models, and the gap shows up most clearly in the shots you take without thinking about settings at all.

Galaxy S25 Ultra video recording quality with 8K and 4K 120fps modes

Video is where this phone feels most like a serious tool. It records 8K at 30fps and 4K at up to 120fps, and the footage looks clean, stable and rich in colour straight out of the camera. Walking shots at 4K 30fps are smooth enough to use without a gimbal, and the phone switches between lenses during recording without the jarring jumps that used to spoil phone video. Audio capture is clear too, with voices staying intelligible over street noise, and the microphones do a good job of rejecting wind when you are walking outside.

I recorded a full afternoon at a street festival in 4K at 60fps, moving between wide crowd shots and close-ups of food stalls, and the footage cut together well afterwards. Colours stayed consistent between lenses, which matters more than any single specification when you are editing, and the stabilisation kept walking shots watchable without extra work. For anyone who films family events, travel clips or short social videos, the video quality here is a genuine reason to choose this phone over a cheaper one. Readers comparing video quality across the range may also want the Samsung Galaxy S26 Review: Design, Software and Camera Quality, which covers how the newer standard model handles the same kinds of shots.

8K video and 4K 120fps slow motion for detailed footage

The 8K mode is best used for scenes where you plan to crop or reframe later, because the files are large and the phone warms up on long takes. I used it for a static shot of a skyline at sunset, then reframed the same clip into a closer view without losing visible quality, and that is the honest use case for 8K on a phone. In practice I reach for 4K 60fps most often: it looks superb on a television, stays manageable in size, and keeps motion smooth. The 4K 120fps mode is a treat for slow motion, turning a skateboard trick or a dog shaking off water into something worth watching twice.

The practical limit is heat on very long 8K takes, so I keep those short and use 4K for anything longer than a few minutes. The phone warns you before it gets too warm, and it has never shut down on me mid-clip, but the 8K files also eat storage quickly, so the 512GB model makes more sense if you plan to film in 8K regularly. Galaxy Log recording is there for people who want to grade their footage, and it gives flat footage with more room to adjust colour afterwards, though it needs editing work to look its best and most people will be happier with the standard colour profile.

Video stabilisation and audio capture while walking and filming events

Stabilisation is the feature that separates good phone video from shaky home movies, and the S25 Ultra does it well. Walking at a normal pace produces footage that looks almost gimbal-smooth, and running produces a gentle bounce rather than a violent shake. Super Steady mode goes further, cropping slightly to deliver very stable footage for action shots, and I used it for cycling clips where the standard mode would have struggled. The trade-off is a slightly narrower field of view, which is a fair price for the stability you get.

Audio is often the weak point of phone video, but here it holds up. Voices stay clear in a crowded room, and the phone separates the speaker from background chatter better than I expected. At an outdoor event with music playing, the recording kept the music full without distorting, and wind noise was controlled well enough that I did not need to re-record. If you film vlogs or family events, pair the phone with a small tripod and you have a setup that covers most situations without extra gear.

Snapdragon 8 Elite for Galaxy performance in games and daily apps

The Snapdragon 8 Elite for Galaxy is a 3nm chip, and in daily use it feels fast in the way that matters: apps open without hesitation, the camera launches quickly, and switching between a dozen open apps never produces a stutter. The Snapdragon 8 Elite for Galaxy also handles Galaxy AI features on-device, from photo editing to live translation, without sending everything to the cloud, which keeps those features quick and private. Heavy apps such as video editors and maps with live traffic run without the slowdowns that used to appear on older flagships after a few months of use.

Benchmarks tell only part of the story, but the lived experience matches the numbers. Scrolling through long photo libraries is smooth, exporting a 4K clip finishes quickly enough that I stopped timing it, and the phone never made me wait for the keyboard or the camera. That responsiveness is the real test of a flagship chip, and this one passes it across weeks of use rather than just in a first-day demo. If you are coming from a phone that is three or four years old, the step up in speed is obvious from the first hour.

Gaming frame rates and sustained speed on the Galaxy S25 Ultra

Games run at high frame rates with detailed graphics, and the large 6.9-inch screen makes the experience closer to a small tablet than a phone. Demanding titles hold their frame rates well in the first twenty minutes, and the phone stays responsive to touch even during busy scenes. I played long sessions of racing and shooting games with graphics set high, and the frame rate stayed stable enough that I never felt the phone was holding the game back. The stereo speakers add to the experience, with clear sound that makes headphones optional for casual play.

The vapor chamber cooling system does real work here, spreading heat across the body instead of letting one hot spot build up under your fingers. The phone does get warm during long gaming sessions, as every powerful phone does, but the warmth stays manageable and the performance does not fall off a cliff after half an hour. That sustained speed is what separates this chip from mid-range parts, which often start fast and fade quickly once they heat up.

Thermal behaviour during long gaming sessions and hot weather

On a hot afternoon outdoors, the phone throttles gently rather than shutting features down, dimming the screen slightly and easing the frame rate rather than stopping the game. That is the right trade-off, and it means you can keep playing, just with a little less brightness. Indoors the phone holds its performance much longer, and I finished hour-long sessions with the frame rate still steady. If you game heavily, a case that does not trap heat helps, and taking the phone out of a thick case during long sessions keeps the cooling working as designed.

Charging while gaming adds heat, so I avoid fast charging during a long session and top up afterwards instead. The phone’s battery care settings can also limit charging speed overnight, which keeps the battery healthier over the years you will own the phone. These are small habits, but they matter when you plan to keep a flagship for four or five years rather than replacing it every year.

Multitasking with split screen, DeX and heavy apps

With 12GB of RAM, multitasking is a strength. I regularly run maps, music, messaging and a browser at the same time, and the phone keeps them all alive without reloading. Split screen works well on the large display, with a video on one side and notes on the other, and the S Pen makes that combination genuinely useful for research and planning. Samsung DeX turns the phone into a desktop when connected to a monitor, and while it will not replace a laptop for heavy work, it handles documents, email and browsing comfortably.

App pairs let you launch two apps together with one tap, and I set up a pair for maps and music that I use on every drive. The recent apps view is quick to navigate, and the phone remembers where you were in each app rather than starting over. For students, travellers and anyone who works from their phone, this multitasking ability is worth as much as the camera, and it is an area where the Ultra’s large screen and generous RAM pay off every day. The comparison with the smaller flagship is worth making here, and the Samsung Galaxy S25 Review: Screen Quality, Cameras and Charging shows what you give up in screen space and battery when you choose the compact model.

6.9-inch QHD+ Dynamic AMOLED 2X display, titanium frame and S Pen design

The 6.9-inch QHD+ Dynamic AMOLED 2X display is the largest on a Samsung flagship of this generation, and it shows in everything from reading to video. Text is crisp at 3120 x 1440 resolution, colours are rich without looking artificial, and the adaptive refresh rate moves between 1Hz and 120Hz depending on what is on screen, saving battery when you are reading and staying smooth when you are scrolling. HDR10+ video looks superb, with bright highlights and deep blacks that make the screen feel bigger than it is.

Outdoors the screen stays readable in direct sunlight, and the anti-reflective coating cuts glare noticeably compared with older phones. I read maps and messages on a bright afternoon without cupping my hand over the screen, which is a small thing until you need it. The flat screen is a welcome change from curved displays, because it makes the S Pen easier to use at the edges and stops accidental touches when you hold the phone. The always-on display shows the time and notifications at a glance, and the ultrasonic fingerprint sensor under the screen is fast and reliable even with slightly damp fingers.

Display brightness, colour and 120Hz refresh rate in daily use

Brightness and colour are the two display qualities you notice every day, and both are strong here. The screen adapts its brightness quickly when you step indoors or outdoors, and the vivid colour mode suits photos and video while the natural mode is kinder for long reading sessions. I use the natural mode for reading and switch to vivid for video, and the phone remembers the setting per app if you set it that way. The 120Hz refresh rate makes scrolling feel fluid, and dropping to a lower refresh rate for static content saves battery without any visible downside.

Eye comfort settings, including a blue light filter and dark mode, work well for evening use, and the screen dims low enough for comfortable reading in a dark room. The large size does make one-handed use a stretch, and I use the one-handed mode often when I am carrying something. That is the price of a 6.9-inch screen, and most buyers will accept it for the extra space it gives to video, maps and split-screen work.

Titanium build quality and water resistance for everyday life

The titanium frame resists scratches better than polished aluminium in my use, and the phone carries IP68 water and dust resistance, so rain and accidental splashes are not a worry. The camera lenses sit in individual rings on the back, which looks cleaner than a raised camera block, and the phone lies flat on a table without rocking. Gorilla Armor 2 glass protects the front, and after weeks in a pocket with keys and coins the screen picked up no visible marks, though I still use a screen protector for peace of mind.

At around 218 grams the phone is heavy, and one-handed use is a stretch for most people, but the weight feels balanced rather than top-heavy. The rounded corners are kinder to the palm than the sharper corners of the previous Ultra, and the flat sides give a secure grip. It is a big phone and it never pretends otherwise, so try holding one in a shop before you buy if you have smaller hands or you carry your phone in a tight pocket.

What the S Pen adds for notes, photo editing and remote control

The built-in S Pen is the feature that no other phone in this range offers, and it is more useful than it looks in a shop demo. Quick notes on the locked screen, precise photo edits, signing documents and sketching ideas all work better with the pen than with a fingertip. I use it to annotate screenshots and to select text precisely, and the handwriting recognition turns my messy notes into searchable text. The pen docks inside the body, so it is always there, and it charges while docked.

The S Pen also works as a remote shutter for group photos, letting you stand in the shot and trigger the camera from a distance. That single trick has saved more group photos than any other feature on the phone. If you never take notes and never edit photos precisely, the pen will stay docked and forgotten, and you should weigh whether the cheaper large-screen model suits you better. For note-takers, students and anyone who signs documents on their phone, the pen alone justifies the Ultra.

5000mAh battery life and 45W charging on the Galaxy S25 Ultra

The 5000mAh battery is the largest in this phone’s family, and it shows in daily use. A typical heavy day for me means an hour of maps and music on a walk, a couple of hours of photos and video, messaging and browsing through the afternoon, and an hour of video in the evening. That pattern ends the day with charge to spare, and I regularly finished the day above 25 percent. On lighter days the phone stretches comfortably into a second day, and the adaptive battery settings learn which apps you use and limit the rest.

Battery life depends on how you use the screen, and the QHD+ resolution and 120Hz refresh rate do cost some power. Dropping to Full HD+ resolution extends the day noticeably, and I use that setting when I know I will be away from a charger for a long time. The 5000mAh battery with 45W charging is a practical combination: a big battery that lasts, and charging fast enough that a short top-up genuinely helps. Readers who want the same battery story in a lighter body should look at the Samsung Galaxy S26 FE Review: Daily Performance and Key Features, which weighs how much battery life matters against size and price in the newer Fan Edition.

Real battery life with camera, maps, video and gaming in one day

Camera-heavy days are the hardest test for any phone battery, and the Ultra passes it. A day of sightseeing with the camera open for hours, maps running and photos uploading in the background still left me with charge for dinner and the journey home. Gaming is the biggest drain, with an hour of demanding play using noticeably more power than an hour of video, so I plan charging around gaming sessions rather than around normal use. Video streaming over Wi-Fi is efficient, and an hour of video costs only a small slice of the battery.

Standby drain is low, and the phone loses only a few percent overnight. That matters more than it sounds, because it means the battery you have in the morning is the battery you can plan your day around. After several weeks the battery health still reads as new, and the battery protection settings that cap charging at 80 percent for daily use will help it stay that way if you mostly charge overnight.

45W wired charging and 15W wireless charging times in practice

Charging with a compatible 45W charger takes a flat battery to about two-thirds in around half an hour in my use, with a full charge taking roughly an hour. That is fast enough for a morning top-up, though it is not the fastest charging on the market, and Samsung does not include a charger in the box. You need a USB-C PD PPS charger and a suitable cable to reach the full 45W, so check what you already own before buying a new one. Wireless charging runs at up to 15W, which is slower but convenient for overnight charging on a stand.

Reverse wireless charging lets you top up earbuds or a watch from the phone, which has saved me more than once when my earbuds ran low during a trip. It is slow, and it drains the phone, but as an emergency option it works. The phone also supports wired reverse charging through USB-C, which is faster for topping up another device when you have a cable handy.

How the charging curve behaves from empty to full

In practice the charging curve matters more than the headline wattage: the phone charges fastest when the battery is low and slows down as it fills, which protects the battery. A ten-minute top-up from a low battery adds a useful chunk of charge, while the last twenty percent takes longer than the first twenty. I charge in the morning while getting ready, and that short window is usually enough to cover the day. For overnight charging I use a slower wireless charger, which is gentler on the battery and always leaves the phone full in the morning.

One UI 7 on Android 15 and Galaxy AI features that matter daily

One UI 7 on Android 15 is the software the phone ships with, and it is the most polished version of Samsung’s interface I have used. The design is cleaner, with simpler settings menus and a notification shade that is easier to read at a glance. Gestures feel natural, animations are smooth, and the phone never stutters when moving between apps. Seven years of operating system and security updates are promised, which means this phone should stay current until the early 2030s, and that long support window is a real part of its value.

The software also brings practical tools that I use every week: a secure folder for sensitive files, a good file manager, and a notes app that syncs with the S Pen. Samsung’s own apps sit alongside Google’s, and while there is some duplication, you can disable the ones you do not use. The phone also includes Knox security, which protects the device at a hardware level, and privacy controls that show which apps have used the camera, microphone and location recently.

Galaxy AI tools for photos, writing and live translation

Galaxy AI is the set of smart features built into the phone, and the useful ones are the ones that save time. The photo editor removes stray objects cleanly, Circle to Search answers questions about anything on screen, and live translation in calls works well enough for a hotel check-in or a restaurant booking. Note summaries turn long meeting notes into short bullet points, and the writing assistant helps draft messages in the right tone. These tools run on-device where possible, which keeps them quick and private.

Not every AI feature earns its place. Some of the generative tools produce results that need checking, and the sketch-to-image feature is fun rather than essential. The features I kept using after the first week were the photo cleanup, the call translation and the note summaries, and those three alone save me time every week. The phone lets you turn off the features you do not want, which is the right approach, and none of them get in the way if you ignore them.

Software updates, privacy controls and seven years of support

Seven years of updates is a long promise, and it changes how you should think about the price. Spread over seven years, a flagship costs less per year than a cheaper phone replaced every two years, and you keep getting new features instead of being left behind. The updates arrive regularly, and security patches come monthly in my experience. The phone also lets you control app permissions in detail, and the privacy dashboard shows exactly what each app has accessed, which makes it easy to spot an app asking for more than it needs.

One practical tip is to check the software update setting when you first set the phone up, and to turn on automatic updates over Wi-Fi. The phone downloads updates in the background and installs them overnight, so you rarely need to think about it. The long support window also helps resale value, because a phone with years of updates left is worth more second-hand than one that has stopped receiving them.

Full Specifications

The table below gathers the key specifications of the Galaxy S25 Ultra in one place, followed by short explanations of what each group of numbers means in daily use. Use it to compare this phone with the other models linked in this article, and to check the details that matter to you before you buy.

Display, chipset, memory and storage specifications

The 6.9-inch display runs at 3120 x 1440 pixels with an adaptive refresh rate from 1Hz to 120Hz, and it supports HDR10+ video. The Snapdragon 8 Elite for Galaxy is built on a 3nm process, which helps both speed and efficiency, and it pairs with 12GB of RAM on every model. Storage comes in 256GB, 512GB and 1TB options, all fast UFS storage, and there is no microSD card slot, so choose your storage size based on how much space your current phone uses. The 256GB model suits most people, the 512GB model suits heavy photo and video use, and the 1TB model is for people who film in 8K or carry large game libraries.

There is no 128GB model, and storage cannot be expanded after purchase, so the choice matters at the point of sale. Cloud storage or a USB-C external drive can cover overflow, but the simplest advice is to buy more storage than you think you need if you keep phones for several years. The RAM management is generous, keeping apps alive in the background, and the chip handles DeX desktop mode without strain.

Camera, video and battery specifications

The rear camera system is a 200MP wide camera, a 50MP ultrawide, a 50MP 5x telephoto and a 10MP 3x telephoto, with optical image stabilisation on the main and telephoto lenses. The front camera is a 12MP sensor with autofocus, and video runs to 8K at 30fps and 4K at up to 120fps, with Galaxy Log for flat-profile recording. The battery is 5000mAh, with wired charging at up to 45W, wireless charging at up to 15W, and reverse wireless charging for earbuds and watches. No charger is included in the box, and you need a USB-C PD PPS charger and a suitable cable to reach the full 45W.

These numbers explain the phone’s character: a camera-first flagship with the battery to support a full day of shooting. The 200MP main sensor gives you cropping freedom, the dual telephoto lenses cover portraits and distant subjects, and the 5000mAh battery means you can use all of it without hunting for a charger by mid-afternoon.

Build, connectivity, sensors and software specifications

The body uses a titanium frame with Gorilla Armor 2 glass on the front and an IP68 rating for dust and water resistance. Connectivity covers 5G, Wi-Fi 7, Bluetooth 5.4, NFC, ultra-wideband and USB-C, with nano-SIM and eSIM support. Sensors include an ultrasonic fingerprint reader under the display, face recognition, accelerometer, gyroscope, proximity, light, compass and barometer. The phone ships with One UI 7 on Android 15 and is promised seven years of operating system and security updates. The built-in S Pen docks inside the body and is included with the phone.

Before you buy, confirm the exact variant for your region, because 5G bands, colours and included accessories can differ by market, and prices move with every sale. The specifications above are the figures Samsung lists for the standard international model, and carrier models can differ in small ways.

Pros, cons and who the Galaxy S25 Ultra is for

The Ultra is the most complete phone Samsung makes in this generation, but it is also the biggest, heaviest and most expensive, and the honest verdict depends on how you use a phone. The strengths are real and easy to list, and the weaknesses are just as real, so weigh them against your own habits rather than against a specification sheet. For a wider view of the family before you decide, the Samsung Galaxy S26+ Review: Build Quality, Software and Daily Speed shows how the newer generation balances the same trade-offs in a slightly different body.

Pros of the Galaxy S25 Ultra

The camera system is the strongest reason to buy this phone, with a 200MP main sensor, a 50MP ultrawide and two telephoto lenses that cover everything from wide landscapes to distant subjects. The 6.9-inch QHD+ 120Hz display is bright, sharp and smooth, and the flat screen works well with the S Pen. Performance from the Snapdragon 8 Elite for Galaxy stays fast across games and multitasking, and the 5000mAh battery lasts a full heavy day with charge to spare. The titanium build feels premium and durable, the S Pen is genuinely useful for notes and photo editing, and seven years of updates make the phone a long-term purchase.

Cons of the Galaxy S25 Ultra

The size and weight are the biggest drawbacks: at about 218 grams with a 6.9-inch screen, one-handed use is a stretch and the phone is heavy in a pocket. Charging at 45W is good but not the fastest on the market, and no charger is included in the box. There is no microSD card slot, so storage cannot be expanded, and the 100x zoom is more of a novelty than a useful tool. The price sits at the top of the range, and buyers who do not use the S Pen or the long zoom are paying for features they may never touch.

Who the Galaxy S25 Ultra is for

This phone is for people who photograph and film a lot, who take notes by hand, who game on their phone, or who want the biggest screen Samsung offers and are happy to carry it. It suits travellers who want one device for photos, maps and entertainment, and professionals who annotate documents and sign forms on the go. It is less suited to buyers who want a light, compact phone, who rarely use the camera zoom, or who would rather save money on a large-screen model without the S Pen. If you are in that second group, the smaller Plus model is the smarter buy, and the choice is about your hands and your habits rather than about quality.

Frequently asked questions about the Samsung Galaxy S25 Ultra

Is the Galaxy S25 Ultra camera good for low light photography?

Yes, the main camera performs well after dark thanks to Night mode and the large 200MP sensor, keeping colours natural and noise controlled in street scenes, restaurants and dim interiors. The ultrawide is usable at night too, though it shows more noise than the main sensor, so use the main camera for your most important low-light shots and hold the phone steady for a few seconds while Night mode gathers light.

Does the Galaxy S25 Ultra support 8K video recording?

Yes, it records 8K video at 30fps, along with 4K video at up to 120fps for slow motion and 4K at 60fps for everyday filming. The 8K mode is best for short clips you plan to crop or reframe, because the files are large and the phone warms up on long takes, while 4K at 60fps is the practical choice for longer recordings.

How long does the Galaxy S25 Ultra battery last in daily use?

The 5000mAh battery lasts a full heavy day in my use, covering maps, photos, video, messaging and an hour of video in the evening with charge to spare, and lighter days stretch into a second day. Charging takes a flat battery to about two-thirds in around half an hour with a compatible 45W charger, and a full charge takes roughly an hour.

Is the S Pen still useful on the Galaxy S25 Ultra?

Yes, the built-in S Pen is useful for quick notes on the locked screen, precise photo edits, signing documents and selecting text, and it also works as a remote shutter for group photos. It docks inside the body and charges while docked, so it is always available, and buyers who take notes or edit photos precisely will use it daily.
