Samsung Galaxy Tab S10 Ultra specs, features and buying guide
The Samsung Galaxy Tab S10 Ultra is a 14.6-inch tablet with a 120 Hz Dynamic AMOLED 2X display, up to 16 GB of memory, an S Pen in the box and IP68 water and dust resistance. It suits people who want one large screen for notes, drawing and split-screen work instead of a laptop plus a tablet.
Samsung sells it as the largest member of the Tab S10 family, and the size is the point: a 14.6-inch 2960 x 1848 panel at up to 120 Hz, with the anti-reflection treatment Samsung lists for the series. The rest of the package is arranged around that screen, from the quad speakers to the S Pen that ships in the box.
Battery and durability are the second half of the story. Samsung rates the battery at 11,200 mAh with up to 16 hours of video playback, supports 45 W Super Fast Charging and rates the tablet IP68 — with the included S Pen rated IP68 as well.
One thing this sheet deliberately leaves out: Samsung does not publish a processor name on its US pages for this model, so no chip row appears here. Where a figure is missing from this page, the manufacturer does not state it.
What to check before you buy the Galaxy Tab S10 Ultra
Two accessories decide how you will actually use it. The S Pen is included, so writing and sketching work out of the box; the 45 W charger is not, and Samsung lists it separately, so a first-time buyer should plan for that.
Memory is the other fork. Samsung lists the Ultra with up to 16 GB of RAM and storage of 256 GB, 512 GB or 1 TB, and the US pages do not spell out which RAM and storage combinations are sold there. If a specific pairing matters — 16 GB with 1 TB, say — check what a given listing actually is rather than assuming.

Key features explained
A 14.6-inch panel that keeps up with a stylus
The screen is a Dynamic AMOLED 2X panel at 2960 x 1848 with a refresh rate up to 120 Hz; Samsung measures it as 14.6 inches across the full rectangle and 14.5 inches once the rounded corners are accounted for. The anti-reflection treatment Samsung lists for the series matters more on a screen this size, because there is simply more glass to catch a window.
The S Pen is in the box, and it is IP68 rated
Samsung includes the S Pen with the Ultra and rates it IP68 alongside the tablet. Because it needs no charging and no pairing, it is the accessory most likely to be used every day — notes, annotations and sketches without reaching for a bag.
Battery sized for a large screen
An 11,200 mAh cell is what a 14.6-inch display needs, and Samsung quotes up to 16 hours of video playback from it. Charging is supported at 45 W Super Fast Charging, with the charger sold separately — worth knowing before the tablet arrives.
Galaxy AI features aimed at notes and screenshots
Samsung lists Circle to Search, Note Assist — transcription, organising and summarising notes — Sketch to Image and Transcript assist, plus Gallery tools including Portrait Studio, Live Effects and Instant Slow-mo, and translation of website and PDF text.
A large screen for notes, drawing and split-screen work
The case for a tablet this size is not portability, it is canvas. At 2960 x 1848 with a refresh rate up to 120 Hz, two documents side by side stay readable, and the S Pen makes annotation as direct as it is on paper — which is why Samsung pairs the pen with the transcription and summarising tools in Note Assist.
The trade is weight and bulk: Samsung lists 718 g for the Wi-Fi model and a thickness of 5.4 mm. That is light for the screen area and heavy for one hand, so it is a device that lives on a desk or in a bag rather than in a pocket.
Battery, charging and how Samsung measures its numbers
Samsung’s 16-hour video figure is not a mixed-use number: it describes local 720p video played full screen with Wi-Fi and mobile data off and set brightness and volume. Real use — streaming, split-screen work and a bright screen outdoors — will draw more, which is why the 11,200 mAh capacity is the more useful fact to carry in your head.
Charging support tops out at 45 W Super Fast Charging, and the charger is a separate purchase. Nothing in Samsung’s published pages suggests the tablet charges faster with a different accessory, so the practical advice is simply to allow for the charger in the budget.
Durability: what IP68 covers and what it does not
Samsung rates the tablet IP68 and describes water resistance in up to 5 feet of water for up to 30 minutes, with the device rinsed of residue and dried afterwards. The S Pen carries the same IP68 rating, which is unusual for a stylus and useful in a kitchen or on a wet campsite table.
Samsung also states plainly that water and dust resistance is not permanent and can be reduced by physical damage or wear. That is the sentence to remember: the rating covers an accident, not a habit, and it is not a licence to use the tablet as a poolside device.
Who should buy the Galaxy Tab S10 Ultra, and who should skip it
Who should buy the Galaxy Tab S10 Ultra
- You want a large canvas for handwritten notes, sketches and annotation, with the S Pen included.
- You want one screen for streaming, browsing and light split-screen work rather than two devices.
- You keep a tablet in places where a splash is possible: IP68 covers the tablet and the S Pen.
- You need expandable storage — microSD support is listed up to 1.5 TB.
Who should skip it
- You need the processor published before you buy: Samsung’s US pages for this model do not name it.
- You expect a charger in the box — the 45 W Super Fast Charger is sold separately.
- You want to one-hand the tablet: Samsung lists 718 g for the Wi-Fi model.
- You need a keyboard included; Samsung lists keyboard accessories separately.
Where the Tab S10 Ultra fits
Note-taking and study
A 14.6-inch canvas with the S Pen included, plus Note Assist for transcription and automatic formatting of what you wrote.
Drawings, sketches and annotated documents
Sketch to Image and the S Pen sit alongside a 120 Hz panel, so strokes land where you put them rather than a frame later.
Streaming and shared screens
Quad speakers with Dolby Atmos and an 11,200 mAh battery rated at up to 16 hours of video playback on Samsung’s own measurement.

Buying the Galaxy Tab S10 Ultra in the US
Start with the two things that ship differently: the S Pen is included and the 45 W charger is not, so a first purchase really is the tablet plus a charger. If you already own a Samsung fast charger of that rating, this is the one place where the price you see is not the whole cost of getting started.
Then settle memory and storage. Samsung sells the Ultra with up to 16 GB of RAM and 256 GB, 512 GB or 1 TB of storage but does not publish which pairings reach the US, so read the listing for the combination you want rather than assuming the line-up mirrors another region. A microSD card up to 1.5 TB is the inexpensive way to add room for video, and it is sold separately.
Frequently asked questions: Galaxy Tab S10 Ultra
