Verified Facts
Samsung is shipping two models in the Tab S11 family. The flagship Galaxy Tab S11 Ultra features a 14.6-inch Dynamic AMOLED 2X display (2960 x 1848) with 120 Hz refresh and peak brightness up to 1600 nits; the smaller Tab S11 offers an 11.0-inch Dynamic AMOLED 2X panel (2560 x 1600). Both run Android 16 with One UI 8 on top.
Under the hood, Samsung cites a MediaTek Dimensity 9400+ processor built on a 3nm-class process. Samsung’s internal tests compare the S11 Ultra to the previous Tab S10 Ultra, reporting NPU gains of 33%, CPU gains of 24% and GPU gains of 27% for AI and multitasking workloads.
The series emphasizes AI-driven features: Gemini Live 3 supports real-time visual input and screen sharing so the assistant can interpret on-screen content; Writing Assist and Drawing Assist refine text and sketches; Circle to Search offers on-screen lookup and translation; and a moveable Galaxy AI overlay can summarize or act on visible content without interrupting workflows.
S Pen improvements include a cone-shaped tip for wider tilt angles and a hexagonal barrel for grip stability. Quick Tools and Sticky Note shortcuts are available while sketching or reviewing documents. The S Pen is supplied in-box (BLE not supported).
| Model | Screen | Battery | Memory/Storage |
|---|---|---|---|
| Tab S11 Ultra | 14.6″ Dynamic AMOLED 2X, 2960×1848 | 11,600 mAh / 45W | 16GB+1TB; 12GB+512/256; microSD up to 2TB |
| Tab S11 | 11.0″ Dynamic AMOLED 2X, 2560×1600 | 8,400 mAh / 45W | 12GB+512/256/128; microSD up to 2TB |
Context & Impact
Samsung positions the Tab S11 series as a productivity-first tablet to compete with other large-screen devices by combining hardware and integrated AI. The One UI 8 rollout begins on these models and will expand to earlier Galaxy tablets, including the Tab S10 series, starting in October 2025.
Upgraded DeX aims to blur the line between tablet and desktop by enabling an Extended Mode that runs DeX across both the tablet and a connected monitor, with drag-and-drop between displays and four separate workspaces tailored for different tasks.
Third-party app partnerships strengthen the creative and productivity case: promotions include trial periods or discounts for Goodnotes, Clip Studio Paint, LumaFusion, Notion and other apps to help users adopt the tablet as a drafting and planning tool.
Design choices — notably a thinner chassis (Ultra at 5.1 mm) and reduced bezels — reflect Samsung’s focus on portability without scaling back display performance or battery capacity, aiming to keep the devices practical for professionals on the move.
