The Lenovo ThinkPad X12 LTE, an aluminum-magnesium alloy, is used in the body of the Lenovo ThinkPad X12. Accordingly, it leaves a high-quality impression. The tablet itself weighs around 750 g and is, therefore, a few grams lighter than the LTE version. The power supply also weighs almost 330 g, and the keyboard dock weighs exactly 340 g. This means that if you take all of your equipment with you to work or travel, you carry around 1.4 kg on your shoulders – ideal for everyone who travels a lot.
|SSD could be bigger
|Excellent battery life
|Only two USB-C ports
|Keyboard dock and stylus included
The dimensions of the tablet module are around 28 cm in length, around 20 cm in width, and 0.9 cm in height. So you can use the ThinkPad X12 comfortably on the couch or in the armchair.

|11th Generation Intel Core i3-1110G4 Processor
(2 Cores / 4 Threads, 2.50 GHz, up to 3.90 GHz with Turbo Boost, 6 MB Cache)
|Integrated Intel UHD Graphics
|28.3 x 20.3 x 0.9 cm
|31.24cms (12.3) FHD, Anti Reflection/Anti Smudge,
400nits, 100% sRGB, Multitouch, Gorilla Glass 5
|28.3 x 20.3 x 0.9 cm
The 13-inch touch display is a real eye-catcher. It offers a resolution of 1,920 by 1,280 pixels in 3: 2 format and Lenovo relies on Gorilla Glass for better protection against scratches.
In terms of maximum brightness, it is still a good 381 candelas per square meter, a bit below the value measured by the X12 LTE – we were able to measure 413 candelas per square meter here. The checkerboard contrast was a good 125 to 1, slightly higher than that of the LTE version. There are clear differences in the contrast under diffuse light because here, it scores 53 to 1, which is significantly better than its big brother, where we were only able to determine 34 to 1. Both devices use an identical panel.
One possible reason for the difference could be the gorilla glass. It would be possible; thanks to the measured values, you can easily use the detachable in brightly lit interiors or outdoors.
|Intel Core i3-1110G4
|Integrated Intel UHD Graphics
|8 GB LPDDR4X 4266MHz
|256 GB M.2 2242 SSD
The Lenovo ThinkPad X12 is completed with 8 GB of RAM and a 256 GB M.2 SSD. This could have been bigger. If you want to install other software in addition to Windows 10 and possibly copy even larger files to it, you will quickly reach your limits and should opt for the 512 GB version.
In contrast to the larger LTE variant, Lenovo uses a smaller processor from the Tiger Lake generation with the Intel Core i3-1110G4. The two-core processor works with a minimum clock frequency of 2,500 MHz and, thanks to Turbo Boost, briefly clocks to 3,900 MHz. It uses the integrated Intel UHD Graphics Xe G4 as the graphics unit. With the GPU, you can easily stream videos, surf the Internet or use Word, Excel, or PowerPoint, for example. Of course, you can also use it to edit one or the other picture. Nevertheless, you shouldn’t set your expectations too high; after all, this type of device is trimmed for mobility.

As usual with 2-in-1 tablets, Lenovo uses two webcams in the ThinkPad X12. The camera on the front has a resolution of five megapixels, and its counterpart on the back has a resolution of 8 megapixels. In terms of video resolution, both cameras offer full HD (1,920 x 1,080 pixels). The built-in microphone is well suited for video calls. You can connect a headset with a jack plug to the combined headphone and microphone jack.
You can connect external Bluetooth devices to the device using Bluetooth 5.2. The connection to the Internet is no problem thanks to WiFi 6 (802.11ax standard).
In addition, the X12 has a fingerprint sensor, a microSD card reader, and a Dolby-certified two-way sound system. Unfortunately, there are only two USB-C ports on the device. Both have a DisplayPort function for this. However, only one of them supports Thunderbolt 4.
Lenovo also includes a matching digital pen. Since there is no space in the housing to store it, there is a loop outside to be attached. It would help if you had AAA batteries or a suitable rechargeable battery to use the pen. Working with a pen is extremely practical and comfortable. Especially users who like to draw or make sketches or drafts quickly will quickly learn to appreciate it.
Coupling between keyboard dock and tablet is quick and easy thanks to the magnetic connection. We measure the dimensions of the plastic keyboard itself at around 28 cm in length and thus fit perfectly to the tablet, for the sake of completeness, other dimensions: width around 22 cm and a height of 0.9 cm.
The keyboard itself has two-stage lighting. When typing on the keyboard, it is noticeable that it still triggers precisely, although it has a short travel distance. After a little practice, typing on the keyboard is fun so that you can quickly write longer texts.
The ClickPad also made a good impression. You can work accurately with the touchpad. The texture of the surface ensures that your fingers do not get caught on it. As usual with Lenovo, the classic TrackPoint should not be missing either.
|Up to 10.1 hours
In terms of battery life, the Lenovo X12 delivers excellent rates. You can watch videos with the tablet for over 11 hours. In terms of surfing, it lasted 8 hours and 45 minutes. The value only drops to 3 hours and 47 minutes in work mode. Nevertheless, the 2-in-1 is a good companion for anyone who travels a lot and wants a device that offers them many options.
The Lenovo ThinkPad X12 scores with outstanding performance values, a fabulous display, and excellent battery life. To connect external devices, you only have the choice between Bluetooth 5.2 or two USB-C ports. That might not be enough for one or the other user. Otherwise, the X ThinkPad X12 is an excellent 2-in-1 for surfing, streaming, and working.
