Samsung Galaxy S25 Ultra 12GB 256GB

Same Ultra, smarter storage pick. The Samsung Galaxy S25 Ultra 12GB 256GB keeps the 200MP camera, Snapdragon 8 Elite for Galaxy, and built-in S Pen — everything that makes the Ultra the Ultra — at a lower step-in price.

Storage is the one compromise against the higher-capacity models. For many buyers, it isn't one at all. If your photos back up to the cloud while your music streams, 256GB of fast UFS 4.0 storage is plenty. Samsung announced the Galaxy S25 Ultra on January 22, 2025. It went on sale in the US on February 7, 2025, with the 256GB model opening the lineup at $1,299.99.

Design and build: thinner, lighter titanium

Samsung trimmed the Ultra without dulling it. The Samsung Galaxy S25 Ultra 12GB 256GB measures 162.8 × 77.6 × 8.2 mm and weighs 218 grams. That makes it slimmer and lighter than the S24 Ultra. The sharp corners are gone too. The frame curves gently into your palm instead of digging in. Long reading sessions feel easier, and landscape gaming is more comfortable. You feel the difference on long commutes.

The frame is titanium, though it doesn't cover the volume and side keys. Corning Gorilla Armor 2 protects the front. The back is matte glass that resists fingerprints well. IP68 covers submersion in 1.5 meters of freshwater for 30 minutes. Still, skip the beach and pool. Water resistance fades with normal wear.

Titanium frame and Gorilla Armor 2

Gorilla Armor 2 is the quiet star here. Its anti-reflective coating cuts glare in sunlight and bright rooms. That matters because you'll use this phone for navigation and photos outdoors. It's also tougher against scratches than last year's glass. With the titanium frame, the phone feels dense and precise. Buttons click cleanly, and nothing flexes.

The S Pen and everyday handling

The S Pen still docks inside the frame. It pops out with a satisfying click. Writing and sketching feel natural with 4,096 pressure levels. Latency is low, so ink keeps up with your hand while you write. One change: the Bluetooth remote gestures are gone. You can't trigger the camera shutter with the pen anymore. The core writing experience is untouched.

Display: the 6.9-inch QHD+ panel

The screen on the Samsung Galaxy S25 Ultra 12GB 256GB grew to 6.9 inches, and Samsung put the space to good use. This Dynamic AMOLED 2X panel runs at 3120 × 1440. Its LTPO backplane scales from 1Hz to 120Hz to match the content. Text looks razor sharp. Colors stay rich but natural. The glass is flat now, so palms won't trigger stray touches.

Peak brightness hits 2,600 nits. Maps and viewfinders stay readable in harsh daylight. HDR10+ adds punch to highlights in movies. When you stop scrolling, the panel can drop to 1Hz. Static pages and the always-on clock sip power instead of gulping it. Meanwhile, outdoor mode boosts contrast further in direct sun.

Refresh rate, brightness and color

The refresh rate works invisibly. Scrolling glides at 120Hz, then the panel relaxes as you read. You can drop to FHD+ to save battery. Still, most eyes won't notice the difference. Vivid and Natural modes remain. Default tuning leans accurate, which photographers appreciate.

Performance: Snapdragon 8 Elite for Galaxy

Every S25 Ultra worldwide uses the Snapdragon 8 Elite for Galaxy. The 256GB model is no exception. It's the first 3nm chip built for Galaxy phones. Samsung claims big gains over the S24 Ultra: 37% faster CPU, 30% stronger graphics, 40% quicker AI. Apps open instantly. Heavy multitasking stays smooth. Galaxy AI features also respond without delay. That headroom shows in photo processing and AI edits.

The 12GB of RAM suits split-screen work and Samsung DeX. DeX turns the phone into a desktop workspace on an external display. The 256GB of UFS 4.0 flash is just as fast as larger capacities. You lose space but not speed. A bigger vapor chamber and new thermal materials sustain performance in long sessions.

CPU, RAM and storage speed

Qualcomm's Oryon cores lead the spec sheet. Two prime cores run at 4.47 GHz for heavy tasks. Six performance cores at 3.53 GHz handle the rest. The Adreno 830 GPU adds ray tracing and Vulkan optimization. UFS 4.0 therefore keeps installs and 8K video saves brisk.

Gaming and heat

Demanding games run smoothly at high settings. The improved cooling keeps the phone warm, not hot, in long sessions. Game Booster can also cap frame rates to stretch battery. The 6.9-inch screen and fast touch response make a fine handheld gaming rig.

Cameras: 200MP main and a sharper ultra-wide

The camera lineup on the Samsung Galaxy S25 Ultra 12GB 256GB is familiar and formidable. A 200MP main sensor with f/1.7 and OIS leads. It joins a new 50MP ultra-wide at f/1.9, a 50MP 5x periscope telephoto at f/3.4 with OIS, and a 10MP 3x telephoto at f/2.4, also stabilized. Samsung's AI ProVisual Engine then refines every shot. All four lenses deliver the detail the Ultra line is known for.

The ultra-wide's jump from 12MP to 50MP is the biggest change. Landscapes hold detail into the corners. Macro shots look crisp instead of mushy. You'll notice it in everyday photos, not just comparisons.

The 200MP main camera

The main camera bins pixels down to clean 12MP or 50MP shots by default. Daylight detail is superb. Colors look true to life. The big sensor and OIS keep night shots bright and clean. Full 200MP mode offers huge cropping freedom, but files are enormous. Cloud backup is therefore your friend here.

The new 50MP ultra-wide

Ultra-wides are usually a phone's weakest camera. Not here. Group shots and interiors come out sharp edge to edge. Macro mode focuses close for dramatic small subjects. It's a clear step up from older 12MP ultra-wides.

Zoom: 3x, 5x and 100x

Two telephotos give real optical reach at 3x and 5x. Adaptive pixel tech fills the gaps with clean 2x and 10x crops. AI-assisted Space Zoom reaches 100x for distant signs, though softness creeps in at the extreme. The 5x periscope is the star for concerts, travel, and sports. It still focuses fast even in dim light.

Video and the front camera

Video is a strength. Shoot 8K at 24 or 30 fps, or 4K at up to 120 fps for slow motion. HDR10+ enriches color. Night video also gets AI noise reduction. Log mode gives editors flat footage to grade. Audio Eraser trims wind and crowd noise afterward. The 12MP autofocus selfie camera handles 4K video calls well.

Battery life and charging

The Samsung Galaxy S25 Ultra 12GB 256GB carries a 5,000mAh battery, matching last year's capacity. The efficient 3nm chip stretches it further. Samsung rates up to 31 hours of video playback in its lab tests. Mixed daily use — messaging, browsing, photos, some video — leaves most people with charge to spare at bedtime. Adaptive battery also learns your routine to stretch standby time.

Wired charging peaks at 45W with Super Fast Charging 2.0. Samsung says a 45W adapter refills about 65% in 30 minutes. The adapter isn't in the box, so bring your own USB-C PD charger. Wireless charging runs at 15W. The phone is Qi2-ready with a magnetic case. In a pinch, Wireless PowerShare can top up earbuds instead.

Software: One UI 7, Galaxy AI and seven years of updates

The Samsung Galaxy S25 Ultra 12GB 256GB ships with Android 15 and One UI 7. Samsung promises seven generations of OS upgrades and seven years of security updates. That support window is rare on Android. It therefore makes the Ultra a genuine long-term purchase rather than a two-year stopgap.

One UI 7 feels cleaner, with smoother animations throughout. The Now Bar surfaces timers, music, and scores on the lock screen. Galaxy AI runs deep: Now Brief gives morning and evening summaries, Circle to Search identifies objects and songs, and Gemini handles multi-step voice requests across apps. Call Assist and Note Assist return with smarter summaries. Personal data stays on-device in Knox Vault. Finally, per Samsung's terms, Galaxy AI is free through the end of 2025.

Connectivity, security and extras

The US model of the Samsung Galaxy S25 Ultra 12GB 256GB covers 5G on sub-6 GHz and mmWave, plus LTE. A nano-SIM slot and eSIM allow dual lines. Wi-Fi 7 with tri-band support is onboard. Meanwhile, Bluetooth 5.4 and ultra-wideband handle audio, finding, and digital car keys. The USB-C 3.2 port supports DeX and fast transfers.

The ultrasonic fingerprint reader works fast, even with damp fingers. Knox and its dedicated Vault chip isolate sensitive data. Knox Matrix extends protection to your other Galaxy devices. Stereo speakers round out movies and games nicely.

Is the Samsung Galaxy S25 Ultra 12GB 256GB right for you?

Buy the 256GB model for the complete Ultra experience — cameras, S Pen, big bright display — while keeping $120 or more in your pocket. It's the rational pick for cloud-first users. Students and commuters who live in the cloud fit here perfectly, so it's an easy recommendation for them. Yet nothing is slower or missing versus its pricier siblings. Heavy 8K shooters should consider 512GB instead.

• Full Ultra feature set at the lowest price in the lineup
• 200MP main camera plus 5x and 3x optical telephotos
• Snapdragon 8 Elite for Galaxy with 12GB of RAM
• Built-in S Pen for notes, sketches and precise edits
• Seven years of OS and security updates
• Titanium build with Gorilla Armor 2 and IP68
• 45W wired charging and 15W wireless with Qi2-ready support

A few honest caveats before you buy:

• 256GB fills up fast if you shoot lots of 8K video, and there's no microSD slot
• No charger in the box — budget for a 45W USB-C PD adapter
• The S Pen lost its Bluetooth remote gestures this generation
• At 218g and 6.9 inches, it's a lot of phone for small hands and pockets
• 45W charging is solid but slower than some rivals' 80W+ speeds
• It's still a $1,299.99 flagship, so the savings are relative

Samsung Galaxy S25 Ultra 12GB 256GB: price, storage and colors

The Samsung Galaxy S25 Ultra 12GB 256GB launched in the US at $1,299.99. That sits below the 512GB at $1,419.99 and the 1TB option. Samsung and carriers discount the lineup within months, and trade-ins can cut the price hard. Student and education discounts can lower it further. Always check current promotions first. Note that Android and pre-installed apps reserve a slice of the 256GB.

Colors include Titanium Silverblue, Titanium Whitesilver, Titanium Gray, and Titanium Black. Titanium Jetblack, Titanium Jadegreen, and Titanium Pinkgold are exclusive to Samsung's store. The box holds the phone, a USB-C cable, and a SIM tool. There's still no charger or case in the box.

Frequently asked questions

Is the 256GB model slower or missing features compared to the 512GB?

No. The Samsung Galaxy S25 Ultra 12GB 256GB uses the same Snapdragon 8 Elite for Galaxy chip and 12GB of RAM as its siblings. Storage uses the same UFS 4.0 technology too. However, only capacity differs. Cameras, display, battery, S Pen, and updates are identical.

Can I add more storage with a microSD card?

No. No Galaxy S25 Ultra model has a microSD slot. If 256GB feels tight, use cloud storage or offload files to a computer over USB-C. You could also step up to 512GB or 1TB. Most streamers will therefore find 256GB comfortable.

Does the S Pen still work as a Bluetooth camera remote?

No. Samsung dropped Bluetooth from the S25 Ultra's S Pen. Air gestures and remote shutter control are gone. Writing, drawing, and highlighting work as before with low latency. Most owners won't miss the remote features, since the pen's main job never needed them.

How long will Samsung keep updating this phone?

Samsung promises seven generations of Android upgrades and seven years of security patches from launch. That covers the phone from Android 15 deep into the 2030s. Few phones match that support window, so it should age gracefully.

Does it support Qi2 magnetic wireless charging?

It's Qi2-ready. Pair it with a magnetic case and Qi2 chargers snap on, since the magnets live in the case itself. Standard Qi pads charge at up to 15W. For the fastest refills, use a 45W wired USB-C PD charger instead of a wireless pad.

What's in the box? Is there a charger included?

The box holds the Galaxy S25 Ultra, a USB-C to USB-C cable, and a SIM ejection tool. There's no wall charger and no case. Reuse an old USB-C PD charger or buy a 45W adapter for the fastest wired speeds.
