Verdict - Lenovo ThinkTab X11 Gen 1
Few other tablets come with such a comprehensive feature set and offer as long battery life as the ThinkTab X11. Lenovo's first Android tablet in the Think family for quite some time offers virtually everything you desire for both business and personal use. However, anyone not benefitting from this wealth of features who is simply on the hunt for a tablet for chilling on the couch will likely be disappointed with the ThinkTab X11's weight.
The choice of chipset is somewhat disappointing in this price range, especially for a tablet. Lenovo has gone with the Snapdragon 7s Gen 3, which is a rather underpowered SoC that often struggles with its 1600p resolution. The brightness and color accuracy also fall short compared to the Poco Pad X1 or Xiaomi Pad 8.
However, users who appreciate the multitude of applications offered by this feature-packed powerhouse from Lenovo will surely be able to live with our criticisms. A comparable tablet experience in the Android realm is virtually nonexistent, and thanks to its rugged case, the ThinkTab X11 is also an attractive option for outdoor enthusiasts or construction site users.

Specifications - Lenovo ThinkTab X11 Gen 1
Case - A waterproof Android tablet with a replaceable battery
Anyone picking up the ThinkTab X11 for the first time is likely to be surprised by its weight for an 11-inch tablet. However, comparable durability-focused devices are similarly heavy. On the plus side, the battery housed inside Lenovo's mid-range tablet is easily replaceable. The 10,200 mAh battery capacity is also very generous for its size.
According to the manufacturer, in addition to IP68 certification, the ThinkTab X11 has passed various tests under MIL-STD-810H, a protection standard used by the US Air Force, Army, and Navy. Corning Gorilla Glass is implemented as the protective glass.
The build quality is appealing, but the plastic casing detracts somewhat from the overall premium feel. Despite this, the slightly rubberized surface on the back doesn't feel cheap. The bezels surrounding the IPS panel are also quite wide, resulting in a screen-to-body ratio of only 80 percent. For comparison, the Xiaomi Pad 8 achieves nearly 86 per cent in this area.
Features - Lenovo's first Thinkpad tablet comes with NFC & a 3.5 mm headphone jack
Lenovo has packed almost everything it possibly can into its mid-range tablet. The ThinkTab X11 really shines with its two USB-C ports. The primary port on the right-hand side of the device supports USB 3.2 with high data transfer speeds.
The second USB-C port on the bottom of the device is USB 2.0. This combination allows users to transfer data or use DisplayPort output while the tablet is plugged in. Headphones for listening to music can also be connected simultaneously via the included 3.5 mm jack.
But the list of features doesn't stop there. The ThinkTab X11 also includes an NFC chip, an e-compass, and a vibration motor. The internal UFS 3.1 storage can also be expanded via an SD card slot. The card slot accepts cards up to 2TB (exFAT) and, in our tests, it achieved a very fast transfer speed of almost 50 MB/s.

Software - ThinkTab X11 Gen 1 with Android 16 & long updates?
Lenovo has equipped its mid-range tablet with its in-house ZUI interface, version 18, based on Android 16. Similar to Samsung devices with DeX support, the ThinkTab X11 can also be used with a desktop-like interface.
The upgrade database lists the ThinkTab X11 as having three major Android versions and four years of security patches, while the EPREL database indicates seven years of support.
Sustainability
The Lenovo tablet comes in (presumably) plastic-free packaging. The manufacturer has provided no information regarding recycled materials, and its carbon footprint is 62 kg CO₂ equivalents. The ThinkTab X11 is listed in the EPREL database with the highest repairability rating of A.
Communication and GNSS - A rugged tablet with 5G, but without WiFi 7
The ThinkTab X11 uses the WiFi 6E standard, which also supports the 6 GHz band. In our tests with an Asus ROG Rapture GT-AXE11000, we achieved high and consistent data transfer speeds.
For mobile internet access, the ThinkTab X11 features an integrated cellular modem, which also enables location tracking via satellite and A-GPS. In addition to a nano-SIM slot, an eSIM is also supported.
Since we only received the WiFi model, we were unable to test the location tracking capabilities.

Cameras - An Android tablet with autofocus for university or school
Unsurprisingly for a tablet, Lenovo hasn't placed a particular emphasis on photo quality with its ThinkTab X11. The main rear camera offers only 13 megapixels and sluggish autofocus. However, image quality is sufficient for snapshots on construction sites or for digitizing documents. Sharpness and color reproduction can be generally described as satisfactory.
The front camera features a fixed-focus 8-megapixel lens, ideal for HD video calls.

Accessories and warranty - The ThinkTab X11 comes with the Lenovo Tab Pen XE & Rugged Smart Case
The ThinkPad X11 comes with a USB-C cable and a quick start guide, and various bundles are also available. Our review unit included a charger, the Lenovo Tab Pen XE with batteries, and the Rugged Smart Case. Lenovo also offers the optional Stylus Tab Pen Plus for around $65, which has a USB-C port for charging.
Retailers typically offer a 24-month warranty, either with a "bring-in" service or via a courier service. According to the data sheet, warranty packages of one or three years are also available.
Input devices and operation - An 11-inch tablet with stylus support & a fingerprint sensor
We were impressed by the ThinkPad X11's precise inputs on its 10.95-inch LCD, whether using a finger or a stylus. For handwritten notes, other tablets offer slightly finer input; however, with the Tab Pen XE, we observed noticeable digitizer trailing during rapid movements.
For secure unlocking, an active fingerprint sensor is integrated into the power button found at the top of the device. It's easily accessible with your index finger and works reliably and quite quickly. Alternatively, a less secure 2D facial recognition via the front camera can be used.
Display - A mid-range tablet, not with OLED, but excellent contrast
The 90Hz panel has a 16:10 aspect ratio and a 1600p resolution. It possesses a sufficiently high pixel density of 276 PPI, although some mid-range tablets offer sharper displays. Xiaomi's consumer tablets in this price range also feature brighter panels.
We achieved the highest brightness in our measurements with the APL18 test pattern, closely followed by an HDR video. Despite this, HDR effects are not optimally reproduced on the PWM-free panel, reaching only around 600 cd/m².

Performance - The Snapdragon chipset inside the ThinkTab X11 comes with speed disadvantages
Lenovo has equipped its mid-range tablet with a Snapdragon 7s Gen 3 that packs 8 GB of LPDDR5 RAM. While the 4nm SoC delivers solid CPU performance, it clearly fell short of the Poco Pad X1 in the Geekbench test. However, the Galaxy Tab Active5 Pro performs at a similar level.
In everyday situations, the system generally runs smoothly, but the Snapdragon chipset sometimes struggles with the display's high resolution. Additionally, the ThinkTab X11 experiences occasional lag.

The integrated Adreno 810 handles graphics processing, but in the GFXBench 4K test, it proved extremely slow at under 10 fps. The result is a device that offers little processing power for its price range. Despite its higher resolution, the Xiaomi Pad 8 achieved over 30fps in the same test.

Speakers
The two speakers support Dolby Atmos and deliver decent sound. However, the low frequencies could be more pronounced, and the very high frequencies get noticeably lost in the pink noise range.
Sound output can be enjoyed either via the 3.5 mm jack or wirelessly via Bluetooth 5.4. The latter offers broad codec support.

Battery life - The ThinkTab X11 delights heavy users with its large, replaceable battery
Power consumption
Although the ThinkTab X11 has a 10,200 mAh battery that supports wired charging at a maximum of 45 watts, wireless charging is not supported.
Power consumption can be best described as efficient. At under 2 watts in idle mode, the Lenovo tablet's power consumption is low. Even under load, the ThinkTab X11 draws less energy than the Galaxy Tab Active5 Pro.

Notebookcheck overall rating
The ThinkTab X11 comes with a feature set that few other current Android tablets can offer. It took almost 15 years for Lenovo to bring a successor to the ThinkPad 18382DG tablet to market, but this one now exists in a standalone product category.
