Lenovo ThinkTab X11 Gen 1: 30-second review

The ThinkTab X11 Gen 1 is Lenovo’s first serious push into rugged Android territory. It arrives with MIL-STD-810H certification, an IP68 rating, and a genuinely useful screwless removable battery.

To avoid the power demands of PC hardware, Lenovo went with an ARM-based architecture, using the Snapdragon 7s Gen 3 to deliver capable everyday performance. This SoC is combined with a modest 10.95-inch display that is sharp and readable outdoors.

One interesting feature in all SKUs is that this tablet has a replaceable battery. But given the exercise to change it isn’t something you’ll want to be doing on a regular basis, this feature is more about extending the tablet’s life, not giving it extended run time with extra batteries.

While it ticks lots of boxes for performance and durability, the one major weakness of this option is its cameras, which are low quality by modern phone standards

The starting price of around £499 is competitive with the Samsung Galaxy Tab Active5 Pro, which appears to be the inspiration for this device.

If your work takes place on a factory floor, a building site, or in a vehicle cab, this is a credible option. Those looking for a general-purpose consumer tablet should look elsewhere, but if you need a go-anywhere tablet for drone flying or collecting data outdoors, this could be one of the best rugged tablet choices.

Lenovo ThinkTab X11 Gen 1: price and availability

How much does it cost? £499/€499

When is it out? Available now

Where can you get it? You can get it from online retailers such as Insight in the UK.

Lenovo announced the ThinkTab X11 Gen 1 at MWC 2026 in Barcelona on 2 March 2026. It’s currently listed as ‘Coming soon’ on the UK website.

Availability was confirmed for Europe, the Middle East, and Africa from April 2026. At the time of writing, Lenovo has not confirmed a US retail date, describing the X11 as a commercial product with pricing starting at €499 in the Eurozone.

What’s likely to confuse customers is the sheer number of SKUs that Lenovo has in this product line, which is ridiculous. In the UK alone, they make eight different options. The differences are primarily the storage capacity (typically 128GB or 256GB) and whether it includes mobile phone comms.

But there are models with no (Beidou + GPS + GLONASS + Galileo + QZSS + A-GPS), because the market for people who don’t want to know where they are is obviously huge. Some models come with a pen, while others do not.

The review hardware was a ZAHL0035GB, which comes with 256GB of storage, the Rugged Smart Case and Lenovo Tab Pen XE, but no slot for a mobile SIM.

That puts it directly in the orbit of the Samsung Galaxy Tab Active5 Pro, which carries a street price of between £499 and £549 in the UK, depending on configuration. Samsung uses the same Snapdragon 7s Gen 3 chipset, so the competition is genuinely close on paper.

The UK retailer Insight carries three models, the cheapest being £563.99 inc. VAT for one with 8GB of RAM and 128GB of storage, but no 5G SIM card slot. The top model has 256GB of storage and is 5G-capable, and has a price of £615.49.

Higher-specified configurations with 12GB of RAM and 512GB of UFS 3.1 storage will command a premium when they become available. Lenovo has not published a full pricing matrix for all SKUs at launch. Business buyers will typically be quoted against volume contracts rather than consumer retail pricing, so the headline €499 figure should be treated as a floor.

Lenovo ThinkTab X11 Gen 1: design

Lightweight
Rubber bumper
Toolless battery change
Camera postioning

Pick up the ThinkTab X11, and the premise is immediately clear. This is not a tablet designed for the sofa. The chassis is thick by consumer standards, sitting at 9.9mm, and the 650g weight is modest for the category but noticeably heavier than a consumer 11-inch slate.

In the review hardware, it came with a soft silicon bumper that didn’t obscure any of the ports and is relatively easy to remove should you want to access the battery compartment.

The MIL-STD-810H certification covers a demanding set of environmental tests. That includes thermal extremes, vibration, altitude, humidity, and shock. The IP68 rating means submersion in up to 1.5 metres of water for 30 minutes, and that’s without a rubber plug in the USB-C port. For field workers in manufacturing, utilities, or construction, these are not marketing checkboxes. They are basic requirements.

To get inside requires one strong fingernail to be inserted into a cutout on the back that then starts popping clips to remove a cover. To be clear, taking this cover off isn’t easy, and it isn’t something I’ve want to do multiple times. But when the tablet arrives, the battery isn’t installed, so it’s necessary to get it working.

Where I’d place this in the Parthenon of replaceable battery systems is that it’s good that you can swap the battery, especially because it could extend the working life of the device, but it isn’t something you would want to consider doing on a regular basis. Eventually, the clips on the cover will fail, and with them goes the environmental protection.

It’s worth noting that you also need to access the battery area for the installation of a MicroSD, or if you have a 5G capable model, the Nano SIM slot. I think an approach more like the Samsung Active5G with screws might have been a better plan, I’d assert.

That said, most tablets don’t allow the battery to be replaced without entirely dismantling the hardware, and battery exhaustion is a major component in tablets and phones reaching the end of their useful life.

The display supports glove and wet-touch input, and it’s designed to work with the Lenovo Tab Pen XE, which comes with some SKUs.

That is an important detail on a site where latex gloves are mandatory, or inclement weather intervenes. The Corning Gorilla Glass should handle the usual workplace knocks, and the front-mounted NFC will appeal to logistics and access-control use cases.

An OLED panel might have been a good option, but the IPS panel used is reasonably colourful, and using something better might have driven the price up.

Dual USB-C ports allow simultaneous charging and peripheral connection without an adapter or dock. Although the second port is clearly also designed for an add-on keyboard, which Lenovo didn’t provide for this review. This is such a useful feature, and SoCs generally support more than one USB port, that I do wonder why other brands don’t offer multiple USB ports.

An external feature I’m not a fan of is the camera’s placement, which is positioned deep in the left corner. The upper corners are the common place to hold a tablet and I found that I activated the camera app and saw nothing, as my hand was obscuring the sensor.

If the camera cluster had been placed in the middle, this could have avoided fingers and also provided more natural framing for image and video capture.

Other than that point, and the nail-breaking nature of the battery cover, the design of this tablet is pretty good.

Design score: 4.5/5

Lenovo ThinkTab X11 Gen 1: hardware

Snapdragon 7s Gen 3
Adreno 810 GPU
10,200mAh battery

The Snapdragon 7s Gen 3 is the same platform Samsung chose for the Galaxy Tab Active5 Pro. On a 4nm process with an octa-core configuration (four Cortex-A720 performance cores and four Cortex-A520 efficiency cores), it delivers capable everyday performance without generating excessive heat in a sealed chassis.

Spoiling my performance reveal slightly, the Snapdragon 7s Gen 3 has a similar performance profile to the MediaTek Dimensity 7400X that I saw recently in the UleFone Amor Pad 5 Ultra.

The Adreno 810 GPU handles the expected range of business and light productivity workloads without difficulty. Video calls, document editing, ERP applications, and camera-intensive tasks are all within its comfort zone. Nobody is buying a MIL-SPEC enterprise tablet for gaming, and the hardware reflects that reality.

Memory options cover 8GB and 12GB LPDDR5, but all the UK SKUs were 8GB. For field workers running one or two dedicated applications, 8GB is sufficient. Environments running multiple concurrent enterprise apps, particularly with persistent background sync, will benefit from the 12GB option. Storage ranges from 128GB to 512GB UFS 3.1, supplemented by a microSD slot.

That combination is practical. Enterprise deployments often include large offline databases, maps, or media libraries. Being able to use a second USB device also allows for an external drive, and it would be easier to replace than the MicroSD card.

The 10,200mAh battery, charged at 45W, should cover a full shift under typical enterprise workloads. Lenovo has not published an official battery life figure. In my testing that I’ll talk about later, it recharges quickly, which makes the overall capacity less of an issue.

As a total capacity of 10,200mAh isn’t huge, and I’ve seen plenty of rugged phones with more, but in this context, it’s enough to get at least two full working days out of the device, and with curation, the better part of a third day.

The front-mounted NFC is an unusual placement. Most tablets put NFC on the rear, which suits tap-to-pay and general contactless use. Positioning it on the front (upper right) of the screen makes it more accessible for door access control and identity verification, where the user faces the reader.

The hardware specification of the Lenovo ThinkTab X11 Gen 1 is decent, and the choice of the efficient SoC has enabled the battery to be scaled to a level where the machine becomes awkward to carry or only suitable for vehicle mounting.

Lenovo ThinkTab X11 Gen 1: cameras

16MP on the rear
8MP on the front
Two cameras in total

The Lenovo ThinkTab X11 Gen 1 has two cameras:

Rear camera: 13MP Omnivision OV13B10, AF, LED flash
Front camera: 8MP GalaxyCore GC08A8

As seems the norm these days, extracting the correct camera sensors from the Android system provided little hard information about the camera sensors. At one point it the primary sensor could have been from Omnivision, Samsung or Sony.

But thankfully, I dug into the replacement parts list on Lenovo, and that revealed that the main sensor is a 13MP Omnivision OV13B10, and the selfie camera is an 8MP GalaxyCore GC08A8.

Anyone with a decent phone will immediately be thinking how underwhelming these sensors sound, and they’re not exactly cutting-edge. I’m not sure why tablet makers immediately assume that their customers don’t need high-quality images, but it’s a cost-saving that many take.

That said, the pictures taken by the 13MP Omnivision OV13B10 are reasonably sharp, and if you don’t activate HDR mode, the colour makes a stab at being representative.

The problem with a 13MP sensor is that there isn’t much margin for errors. There is no anti-shake compensation, only two levels of digital zoom (1X and 2X), and there are no special modes, like panorama or time-lapse, whatsoever.

However, there are two functions that people will like, the first being that there is a specific camera mode for capturing documents. That’s useful, and the other thing that impressed me is that even with only a 13MP sensor, it will capture both 2K and 4K video. There is no means to change the FPS; it’s 30 FPS by default, but at least you can capture a proper resolution.

I won’t talk about the 8MP fixed focus front-facing camera, to avoid annoying anyone at GalaxyCore. But that it can only capture 1080p video is probably a good thing.

Overall, if you have good lighting conditions, you can make the 13MP Omnivision OV13B10 work for photography and video. Though I wouldn’t expect miracles, and it might have been a better plan if Lenovo had splashed out another dollar or less for a 32MP Samsung sensor.

Normally, I’d present the numbers of the review machine against a prior tablet in this instance, but I chose not to here.

That’s because no other tablet I’ve tested could get anywhere near these numbers, including some of the previous Ulefone Pad series. For example, the Ulefone Armor Pad 3 Pro scored only 296 and 1358 on the Geekbench single and multithreaded tests, which is a fraction of what this tablet offers.

Equally, GPU power is a magnitude better with the Pad 3 Pro, managing only 647 points on WildLife, or 18%. I’m sure there are Android tablets available that could go toe-to-toe with the Pad 5 Ultra, but I’ve yet to see them.

Another area this design excels in is battery life, even if I had some issues with getting PCMark to completely exhaust the battery without crashing. That’s not a problem specific to this tablet; it seems to happen with many tablets and phones, where something happens in the background that trips up the PCMark tool.

After running it a number of times, the best result I got was that it ran for 28 hours and 27 minutes, but there was still 39% of the battery capacity left. That result indicates that the total running time of the test using all the battery would be around 46 hours or more, which is substantial.

Using the provided 120W charger, it can recover about 27% of capacity in 30 minutes. That puts the total recovery from empty at between two and three hours. There is no wireless option, and given the battery’s size, that’s probably not a bad thing.

Overall, the performance of the UleFone Armor Pad 5 Ultra is top-notch, and dramatically better than most rugged Android tablets.

Lenovo ThinkTab X11 Gen 1: Final verdict

I’m going to make one complaint that has nothing to do with the hardware-software combination Lenovo has created. It’s the naming convention.

When I live and breathe platforms on a daily basis, and I can even get confused, then something is badly wrong. Calling something a Lenovo ThinkTab X11 when you already have a Lenovo ThinkPad X11 is a patently dumb idea. And this recent thing of calling them Gen 1 and so on, that’s hyperbolically stupid too.

Here’s a ‘next-gen’ idea: stop now! Lenovo makes far too many SKUs of all its products, and naming them so similarly only causes further customer confusion. Someone wanting an Android tablet doesn’t need a degree in the nuances of Lenovo product naming conventions, if there are any. Rant over, and I should say that this problem isn’t exclusive to Lenovo; it’s all over the commercial platform space.

For the purpose of this review, the ThinkTab X11 Gen 1 is a well-considered entry from Lenovo into a market that Samsung has dominated for years. The removable battery alone separates it from most of the competition. In a sector where devices must survive shifts rather than evenings on the sofa, that matters.

The Snapdragon 7s Gen 3 provides enough headroom for the applications that enterprise Android tablets actually run. The IP68 and MIL-STD-810H certifications are genuine rather than decorative. The dual USB-C configuration is practical and is something that competitors typically do not offer.

There are only two areas that the ThinkTab X11 Gen 2 should embrace when it inevitably arrives. One is to repackage the battery so that the cover is part of the battery, and swapping them in and out is easier. And the other area that needs to be addressed is the cameras, which need to be brought up to the level of entry-level phones from today, not ones from five years ago.

With those things addressed, this would be the perfect rugged tablet solution for many people. In the meantime, the ThinkTab X11 Gen 1 is an affordable option that isn’t a bad device, though Lenovo could have made it even better with a bit of adaptive thinking.
