The Samsung Galaxy Tab S12 Ultra aims at the top of the Android tablet market with a huge OLED display, high-end performance, and battery endurance that stretches through an entire day. Starting at $1,400, this tablet also carries an apex price, so every major feature has to justify the cost.
Its strongest case begins with the screen and continues through the processor, memory, storage, and battery. Yet the design includes a clear trade-off: the Galaxy Tab S12 Ultra offers a single USB-C port, limiting the number of connections available from the tablet itself.
A Massive OLED Display Built for Speed
The Galaxy Tab S12 Ultra features a 14.6-inch OLED display with a peak brightness of 1,600 nits. That combination gives the tablet a large viewing area and strong brightness on paper, while the 120Hz variable refresh rate adds a smoother screen experience than a fixed refresh rate can provide.
The display stands as one of the tablet’s defining features because its size, OLED panel, brightness, and refresh rate all work together as one major advantage. A 14.6-inch screen gives the S12 Ultra a presence closer to a large workspace than a compact tablet, while the 120Hz variable refresh rate lets the panel adjust its refresh rate instead of staying locked to one setting.
That screen comes inside a body that measures just 5.1mm thick and weighs 692 grams. Those numbers make the tablet thin for its size, but the large display still creates a substantial device. Samsung uses an aluminum chassis, and the construction is described as surprisingly strong with only a hint of flex.
Performance Reaches the Top Tier
Inside, the Galaxy Tab S12 Ultra runs on a MediaTek Dimensity 9500 chip with 12GB of RAM and 256GB of storage. This hardware gives the tablet a strong foundation for demanding performance, while the storage and memory figures establish a clear high-end configuration.
The benchmark result backs up that positioning. In Geekbench 7, the S12 Ultra posted a multi-core score of 9,403, putting a precise number behind its performance claims. The result matters because a large tablet needs more than a dramatic screen to feel like a premium device; its processor and memory must keep pace with the scale of the hardware.
The tablet’s design creates a contrast between ambition and simplicity. The aluminum chassis is strong, the body is only 5.1mm thick, and the internal hardware reaches high performance, but the device has a single USB-C port. That limited port selection is one of the clearest compromises in a product that starts at $1,400.
Battery Life Takes Center Stage
The Galaxy Tab S12 Ultra includes an 11,600mAh battery, and its endurance result is one of the most compelling facts about the device. On a local video rundown test, the tablet lasted 19 hours and 39 minutes.
That testing result gives the S12 Ultra a major battery advantage on paper. A tablet with a 14.6-inch OLED display, 1,600-nit peak brightness, and 120Hz variable refresh rate has demanding hardware to power, yet the device still reached 19 hours and 39 minutes in the local video rundown test.
Battery life becomes even more important because the tablet combines a very large display with a thin body. The 11,600mAh capacity supports the device’s central promise: deliver a large, bright, fast screen without making endurance an afterthought.
Cameras Add Flexibility, Not Excess
The camera system covers the core roles expected from a high-end tablet. The Galaxy Tab S12 Ultra has a 12-megapixel selfie shooter, a 13MP rear wide lens, and an 8MP ultra-wide rear lens.
That setup gives the tablet one front camera and two rear lenses, with the rear system pairing a wide lens with an ultra-wide lens. The camera hardware does not change the tablet’s main identity, but it rounds out the feature set alongside the OLED display, MediaTek Dimensity 9500 chip, and large battery.
The Galaxy Tab S12 Ultra makes its pitch through scale and performance: a 14.6-inch OLED display, 12GB of RAM, 256GB of storage, a Geekbench 7 multi-core score of 9,403, and 19 hours and 39 minutes in local video testing. Its aluminum chassis adds strength, while the 5.1mm thickness keeps the design impressively thin.
The price and single USB-C port remain the biggest pressure points. At $1,400, the tablet needs its display, speed, build, and endurance to matter to every buyer, but those strengths make its position clear: the Galaxy Tab S12 Ultra is built as an apex Android tablet for people who want the largest screen and strongest feature set Samsung offers in this form.
