Lenovo ThinkTab X11 Review: A Work Tablet With a Removable Battery

Lenovo pitches the ThinkTab X11 squarely at work: a light, mobile, flexible Android tablet meant to simplify the office day, whether on the move, at a desk or in a meeting. Independent lab testing found a device built for practicality over show — and one with a couple of genuinely unusual tricks. This review is based on that laboratory test, not our own hands-on trial.

The X11 keeps things plain: a matte-black body with rounded corners, wide screen borders and the familiar ThinkPad accents, right down to a red dot on one button. At 25.7 x 16.9cm and 10mm thick it is compact enough for a bag without being wafer-thin, and its 650 grams strike a sensible balance — light enough to carry, solid enough not to feel like a toy. A stylus is included for sketches and handwritten notes, a welcome extra on a working tablet. It sits naturally alongside the picks in our best tablets guide.

Under the shell is a modern mid-range engine rather than a powerhouse: a Qualcomm Snapdragon 7s Gen 3 with Adreno 810 graphics and 8GB of RAM for multitasking. In raw benchmarks it was ordinary — 2,902 in Geekbench — but in daily use it feels noticeably brisker, with high interface responsiveness and a pleasingly low 63-millisecond touch latency. In short, a comfortable everyday worker for apps, browsing, office tasks and notes rather than a racing machine. Storage is 256GB, expandable by microSD up to a further 2TB.

The 10.9-inch panel runs at a practical 16:10 ratio and a high 2560 x 1600 resolution, giving a crisp 277 pixels per inch so text, icons and web pages look sharp. Measured peak brightness of 617 candela per square metre is strong, though the 1,481:1 contrast could be higher. Colour coverage reaches 96 percent of sRGB but only 74 percent of the wider DCI-P3 gamut, and a 90-hertz refresh keeps motion smooth. For a more colour-accurate Android alternative, our Samsung Galaxy Tab S11 review is worth a look.

The standout sits under the back cover: a 10,200mAh battery that lifts out without tools — something very few tablets allow. There is even a Batteryless Mode that runs the tablet straight from mains power with no battery fitted, handy for fixed installations such as a vehicle. Endurance is strong too, comfortably beating twelve hours in the continuous-use test — a full working day with reserve. Charging is quick, hitting 20 percent in 15 minutes, 76 percent in an hour and full in about 90 minutes at up to 48 watts; there is no wireless charging.

The other clever touch is two USB-C ports, so a keyboard can stay plugged into one while the tablet charges from the other. A fingerprint sensor handles unlocking, and Wi-Fi 6E covers the network. The cameras surprised the testers: the 13-megapixel rear lens took high-quality shots in daylight and low light, firing in 134 milliseconds and recording 4K video at 30fps (though without slow-motion or zoom), while the 8-megapixel front camera handled video calls well, its 66-degree field of view wide enough for two people. For a thinner, more consumer-focused Android slate, see the Honor MagicPad 4.

The Lenovo ThinkTab X11 is a robust work tablet with a clear focus on practicality. It scores with a sharp, bright screen, long-lasting and swappable battery, the unusual Batteryless Mode, the handy twin USB-C ports and a bundled stylus. The performance is fine for everyday work, office duties and note-taking but stays firmly mid-range, and the contrast is average. The upshot is a tough, clever companion for the job, travel and even a service vehicle — so distinctive that, right now, there is nothing quite like it.
