Lenovo ThinkTab X11 Review: A Tablet With a Swappable Battery

With the ThinkTab X11, Lenovo has brought out a tablet that puts productive work at the centre of everything. Light, mobile and flexible, it is meant to simplify the working day — on the move, at a desk or in a meeting. The concept works better than the spec sheet suggests, largely because of one component almost nobody else offers.

Visually the ThinkTab X11 chooses restraint over bling: a matt black casing, rounded corners, wide display bezels and the familiar Think accents, including the red splash of colour on one key.

At 25.7 x 16.9 centimetres it is compact enough for a bag, though at 10 millimetres thick it is no wafer-thin slab. The back looks robust and tidy, with camera and logos set at the edge. At 650 grams it is a reasonable weight for a work tablet — light enough to carry, heavy enough not to feel like a cheap toy.

Under the shell is not an inflated powerhouse but a modern mid-range engine. The Qualcomm Snapdragon 7s Gen 3 is meant to handle apps, browser tabs and office tasks briskly in everyday use, while the Adreno 810 graphics chip keeps the display smooth. Alongside it sit 8 gigabytes of memory, intended to give enough headroom to run several apps in parallel without constant reloading.

The speed measurements confirm the character: this is a comfortable everyday worker rather than a racing machine. Raw working speed came out only middling at 2,902 Geekbench points. In direct use, though, the tablet feels distinctly quicker than that: interface responsiveness is high, and screen input lag was a pleasantly low 63 milliseconds.

The 256 gigabytes of storage leaves room for apps, documents, photos and offline content, and if that is not enough it can be expanded by up to 2 terabytes with a microSD card.

The display is the tablet's small stage: 10.9 inches, in a practical 16:10 format, and nicely high resolution at 2,560 x 1,600 pixels. Across the usable area of 23.5 x 14.7 centimetres that gives a high pixel density of 277 ppi, so text, icons and web pages appear pleasantly sharp.

Measured maximum brightness of 617 candela per square metre gives good luminance, though the contrast ratio of 1,481:1 could happily be higher. The panel reproduces colour almost faithfully with 96 per cent sRGB coverage, but manages only 74 per cent of the larger DCI-P3 space. A 90 hertz refresh rate makes movement look smooth. A stylus is included for sketches and handwritten notes, which is a genuine plus at this level.

The real highlight sits under the back cover: the 10,200 mAh battery can be removed without tools, something very few tablets allow. There is also a Batteryless Mode in which the ThinkTab X11 runs directly from the mains with no battery fitted at all — practical for fixed installations, in a vehicle for instance.

It has serious stamina too. In the continuous-use test scenario the Lenovo lasted well over twelve hours, which is enough for a long working day plus reserve. Charging is quick as well: over the cable the battery was full again after an hour and a half, reaching 20 per cent after 15 minutes, 39 per cent after 30 minutes and 76 per cent after an hour. With charging power of up to 48 watts it recovers around eight minutes of runtime for every minute on charge. Wireless charging is not supported.

Instead it has two USB-C sockets, and there is a good reason for that: accessories such as an attached keyboard can be used while the tablet charges through the second port.

Also welcome: a fingerprint sensor unlocks it comfortably, and at home or in the office it connects over fast Wi-Fi 6E.

The cameras performed surprisingly well. The 13-megapixel rear lens took high-quality photos in daylight and in low light, with a shutter delay of 134 milliseconds, and it records video in 4K at 30 frames per second — though there is no slow motion and no zoom function.

The 8-megapixel selfie camera on the front also convinced. It takes good images on video calls, and with a 66-degree field of view it captures two people sitting in front of the tablet.

The Lenovo ThinkTab X11 is a robust work tablet with a clear focus on practicality rather than show. It scores with a sharp, bright display, a long-lasting and swappable battery, and the accompanying Batteryless Mode. The two USB-C sockets are unusual but useful, and a stylus is included.

The pace is enough for everyday use, office work and note-taking, but it remains mid-range. The balance: a tough, clever companion for work, travel and service vehicles — and unusual enough that there is currently no comparable tablet on the market.
