Lenovo ThinkPad X1 Nano Laptop Review - Less than 1 kg for the Business Subnotebook with LTE

16:10 is back! Lenovo returns to the roots of the X1 series with the new ThinkPad X1 Nano and includes a 13-inch panel with a 16:10 aspect ratio. It weighs less than 1 kg, so it is a very interesting device for mobile users, but the keyboard does not meet the high standard we are used from ThinkPads. Update: New information about the keyboard
Andreas Osthoff 👁 (translated by Andreas Osthoff), 🇩🇪 🇳🇱 ...

Lenovo expands its ThinkPad X1-series with the new 13-inch X1 Nano, which is the first ThinkPad that returns to a 16:10-inch screen. It tips the scale at little more than 900 grams, so it is a very mobile companion and reminds us of the old ThinkPad X300 from 2008, which was a direct competitor for the new MacBook Air back then. The technology has evolved quite a bit in 13 years, and pretty much every manufacturer offers very mobile business laptops.

Our review unit carries the designation ThinkPad X1 Nano 20UN002UGE for about 2200 Euros. Customers with access to Lenovo's Campus program pay ~1900 Euros for this spec. You get a modern Core i7 CPU from Intel (Tiger Lake UP4), 16 GB LPDDR4x-RAM, 512 GB PCIe SSD storage, an integrated LTE modem, and a matte 13-inch IPS panel (16:10) with the 2K resolution (2160 x 1350 pixels).

The primary rivals for the X1 Nano are devices like the Dell XPS 13 9310, Fujitsu LifeBook U9310X, HP Elite Dragonfly or the MacBook Air M1. We will also include the ThinkPad X13 AMD in the comparison tables. It is a bit bulkier and heavier, but also more affordable and powered by a much faster AMD CPU in return.

Update 02/04/21: Our original news about the upcoming ThinkPad X1 Carbon G9 and ThinkPad X1 Yoga G6 included incorrect information about the keyboard. Both models will get an updated keyboard, but the key travel stays at 1.5 mm for most keys like on the current models. Only the upper row with the function keys will get a reduced key travel of 1.35 mm similar to the ThinkPad X1 Nano.

Case - X1 Nano with Carbon Fiber and Magnesium Chassis

Combination of carbon fiber and magnesium alloy
Combination of carbon fiber and magnesium alloy

The design of the new X1 Nano does not offer any surprises; it is pretty much a slimmed-down version of the ThinkPad X1 Carbon. This includes the black chassis as well as the tapered front of the base unit. The height is just ~14 mm at the front and 16.7 mm at the rear. If you get the optional touchscreen, the unit will be a bit thicker (14.27-17.2 mm) and about 60 grams heavier.

The haptic feeling of the smooth surfaces is also identical to the larger ThinkPad X1 Carbon, but this also includes the susceptibility for dirt and fingerprints. You can get the X1 Nano either with the black lid or a carbon fiber pattern, but the latter is just printed on the lid.

Lenovo still uses a magnesium alloy construction for the base unit, which is very sturdy. Twisting attempts are no problem, only the center area of the keyboard can be pushed down a bit under a lot of pressure. However, this should not be an issue in practice.

The lid is made of carbon fiber and also very sturdy. We cannot provoke picture distortions or ripples on the screen, even with a lot of concentrated pressure from behind. Twisting attempts are no problem, either, and you can even lift the whole laptop at one of the upper display corners as you can see in the two pictures (the brightness difference on the screen is a reflection from the background and no picture distortion caused by the lifting at the corner). 

The two hinges are very well adjusted, because they keep the display securely in position at every opening angle (up to 180 degrees). it is still possible to open the lid with just one hand. All in all, a very convincing performance of the new X1 Nano.

Only the XPS 13 is slightly thinner than the X1 Nano in our size comparison, and the two models are also neck and neck and the most compact ones here in terms of footprint. 

The X1 Nano has the edge when we look at the weight, and especially the XPS 13 and the MacBook Air are more than 300 grams heavier. The compact 65W power adapter tips the scale at 323 grams.

X1 Nano vs. X1 Carbon

Even though the X1 Carbon G7 is not a direct competitor to the new X1 Nano due to the larger screen, we still compared the two devices. The larger X1 Carbon is actually just ~130 grams heavier and the thickness is comparable as well. The footprint on the other hand is a noticeable difference. The X1 Carbon is already pretty compact for a 14-inch device, but the X1 Nano is noticeably smaller.

Connectivity - Lenovo implements 2x Thunderbolt 4

The port variety of the X1 Nano is heavily limited compared to other ThinkPads. You only get a 3.5 mm stereo jack and two modern USB-C ports with USB 4 and Thunderbolt 4 support, which can be used for charging and external displays DisplayPort 1.4a, maximum resolution 5120 x 3200 @60 Hz). It can drive up to three independent displays.

This means you will often need adapters and one of the two USB-C ports is often blocked by the power adapter. The right side only accompanies the fan exhaust and the power button. Lenovo could have relocated it to the top of the base unit (similar to the upcoming X1 Carbon G9) in order to make room for a regular USB-A port. There is no slot for a Kensington Lock, either.

Communication - Wi-Fi 6 and integrated LTE

4G module from Fibocom, optional 5G module from Qualcomm
4G module from Fibocom, optional 5G module from Qualcomm

The ThinkPad X1 Nano is equipped with the current AX201 Wi-Fi module from Intel, which supports all common standards including 802.11ax (Wi-Fi 6). We determine decent transfer rates above 1.2 Gbps in our standardized test with the router Netgear Nighthawk RAX120. We also tested the X1 Nano with a Frtiz!Box 7590 and there were no problems.

You can order the notebook with a WWAN module, but you cannot upgrade it later (antennas and SIM slot are not installed). Our test unit uses an LTE module from Fibocom (Cat.9), which worked perfectly with our Nano-SIM from T-Mobile. Lenovo also offers a 5G WWAN module from Qualcomm (Snapdragon X55).

Webcam - 720p with Mechanical Shutter

The webcam is still a simple 720p module and the picture quality is mediocre as we expected it. It does its job, but considering the current situation with home-office and plenty of video conferences, we would like to see better modules. You also get a mechanical shutter (Think Shutter), which is easy to use. Lenovo also implements an IR camera for Windows Hello.

Maintenance

The bottom panel can easily be removed with a simple Philips screw driver. There are no annoying plastic clips. However, there is not that much to do on the inside, because you can only access the WWAN module and the M.2-2242 SSD. RAM and WLAN module are soldered onto the mainboard. The battery is secured with screws and can also be removed. The fan on the other hand is completely covered.

Input Devices - Reduced Key Travel

Keyboard

The smaller chassis also results in a reduced keyboard size, which can be noticed at many spots: The upper row of function keys is slimmer (8 vs. 10 mm on the X1 Carbon), the regular letter keys are smaller (15x15 vs. 16x16 mm on the X1 Carbon) and some of the keys on the right side of the keyboard are even narrower at just 12 mm. The reason is the limited chassis width of the X1 Nano so we can understand this compromise. We also believe you will get used to it after a little adjustment period.

The bigger problem is the key travel. Lenovo has already reduced the key travel on the X1 Carbon from 1.8 mm to 1.5 mm two generations ago, which is definitely noticeable during typing. The new X1 Nano (and also the upcoming X1 Carbon G9 and X1 Yoga G6) only gets 1.35 mm key travel. This does not sound like a big difference, but it is clearly perceptible. The familiar rich feedback is gone and it is the worst ThinkPad keyboard you can get in terms of typing experience. Even entry-level models from the ThinkPad E and L-series have an advantage in this respect.

In isolation, the keyboard is not bad, because the key stroke is still very precise and there is no clattering. You also get used to the keyboard pretty quickly. We did use it to write some texts and it was okay, but the problem is when you go back to another ThinkPad (in our case a ThinkPad X1 Carbon G7) and you immediately notice that the quality of the new keyboard is worse. The trend towards slimmer devices seems to be unstoppable, but we believe Lenovo unnecessarily gives up a major strength of previous ThinkPad generations.

The keyboard of the X1 Nano is still better compared to the Fujitsu LifeBook or the MacBook Air, but the input devices of the Dell XPS 13 and the HP Elite Dragonfly are not worse. The ThinkPad X13 on the other hand has a better keyboard.

Lenovo uses two different suppliers for the keyboard. our review unit is equipped with the model from Chicony, but there is another version from Lite-On. At this point we cannot say if and how the two versions differ. 

As per usual, the keyboard is spill-water resistant and equipped with a two-stage background illumination.

Touchpad & TrackPoint

Lenovo does not remove the familiar TrackPoint and also includes the according buttons above the touchpad. However, this means the space for the touchpad is limited (10 x 5.6 cm). Both input methods work well in practice and all the buttons create an even and dull clicking noise.

Display - ThinkPad with 16:10 Screen

Subpixel array

No visible backlight bleeding (IPS glow in the corners is enhanced by the camera)
No visible backlight bleeding (IPS glow in the corners is enhanced by the camera)

Lenovo offers two different display, but they share the same basic specs and the only difference is the additional touch layer. The IPS panel with an aspect ratio of 16:10 offers a resolution of 2160 x 1350 pixels (196 ppi) and creates sharp images. The colors also look very rich and the response times are okay. The subjective picture quality is very good.

We can only confirm the advertised brightness of 450 nits in the center of the screen; the average value is slightly lower at 434 nits. The black value is decent at 0.27 cd/m², which results in an excellent contrast ratio of more than 1700:1. The screen also supports HDR contents.

We did not detect PWM flickering and there is no visible backlight bleeding even on a black screen at maximum brightness.

* ... smaller is better

We use the professional CalMAN software in combination with the X-Rite i1 Pro 2 spectrophotometer for our analysis. The factory calibration is already very good. There is no color cast in the grayscale, the color temperature is fine and even the color deviations (compared to the sRGB reference) are lower than 3, which means the human eye cannot see a deviation from the ideal colors.

A calibration by the user is therefore not necessary. We tried it anyway, but only got minor improvements. The panel also covers sRGB, which means you can use it for picture/video editing.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined↗ 13.2 ms rise
↘ 14.8 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 60 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.3 ms).
       Response Time 50% Grey to 80% Grey
46.8 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 24.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9687 (minimum: 5 - maximum: 142900) Hz was measured.

You obviously benefit from the matte surface outdoors. We took our test pictures in the winter sun, and reflections can be challenging. If you turn away from the sun, however, you can use the panel very comfortably even in this bright environment. The viewing angle stability of the IPS panel is very good.

Performance - Tiger Lake and M.2-2242-SSD

Lenovo offers two processors from Intel's current Tiger Lake generation for the X1 Nano. However, these CPUs are not the "standard" UP3 chips, which are available for a couple of months now, but more efficient UP4 chips (Core i5-1130G7 & Core i7-1160G7) with a lower TDP specification (at least in theory). The X1 Nano is always equipped with 16 GB memory (LPDDR4x-4266) in the EMEA region, other regions also get models with 8 GB. The memory is soldered onto the mainboard and cannot be upgraded.

Processor - Core i7-1160G7

Our test unit uses the faster Core i7 chip. The Core i7-1160G7 is a Tiger Lake chip with four cores (8 threads) and all four cores can reach up to 3.6 GHz; one active core up to 4.4 GHz. Intel specifies the TDP with 7-15W for the UP4 chip, but Lenovo sets both limits to 40W. This means the chip temperature is the deciding factor for the performance.

The good news is that all four cores can maintain their maximum clock for about one minute, while the CPU consumes 36W. This begs the question why Lenovo uses a supposedly slower UP4 processor in the first place.

CPU data Cinebench R15 Multi loop

A closer look at the Cinebench R15 Multi loop shows that the performance is not perfectly steady, and it depends how long the chip can higher clocks in the beginning of each run. The power consumption levels off at around 19W (~2.5-2.6 GHz). The results are slightly behind the XPS 13 with the UP3 Tiger Lake CPU and clearly ahead of the old Comet Lake CPUs. The passively cooled MacBook Air, however, is even faster, even though Cinebench R15 has to be emulated on the Air M1. The ThinkPad X13 with the AMD Ryzen processor is clearly superior in multi-core tests and offers almost twice the performance.

* ... smaller is better

The i7-1160G7 benefits from the high clock (4.4 GHz) in the single-core benchmarks, and we see the maximum clock in the tests. The X1 Nano is only beaten by the more powerful Core i7-1165G7 in the XPS 13 and in some tests also by the Apple M1. The AMD processor of the X13 on the other hand is beaten. The CPU performance is not reduced on battery power.

All in all, the CPU performance of the X1 Nano is much better than we expected (considering the supposedly low TDP of the UP4 processor).

M.2-2242-SSD from Western Digital

Lenovo implements a compact M.2-2242 SSD, which is provided by Western Digital (SN530) in the case of our review unit. We do not understand why Lenovo does not use the modern PCIe 4.0 interface, which is supported by Intel's Tiger Lake chips. However, PCIe-3.0-x4 is still a very fast interface and you will not notice the difference in practice.

GPU Performance - Xe Graphics G7 with 96 EUs

GPU-Z Intel Xe Graphics G7
GPU-Z Intel Xe Graphics G7

Even though it is a more efficient UP4 processor, Intel still combines it with the powerful integrated Xe Graphics G7 with 96 execution units. The ThinkPad X1 Nano benefits from the TDP and the fast LPDDR4x memory. As we have seen in our reviews, the performance of the iGPU will be slightly reduced with common DDR4 memory. there is also one limitation compared to a regular UP3 Xe Graphics G7: The core clock is lower at 1100 MHz compared to 1300-1350 MHz (depending on the CPU).

The synthetic 3DMark benchmarks show that the X1 Nano is 10-14 % slower than the average values for the Xe Graphics G7 in our database. Intel's iGPU is still faster than the RX Vega 7 of the ThinkPad X13. We use GFXBench for the comparison with Apple's M1 GPU. Both models of Apple's GPUs (with 7 or 8 cores) are much faster and Intel's iGPU does not stand a chance (+80-115 % depending on the setting). The old UHD Graphics chips from the Comet Lake generation are clearly beaten.

The performance of the iGPU can be maintained; the 3DMark stress test (Fire Strike) is passed at 99 %. There is no performance reduction on battery power.

Gaming Performance

You can play some games with the Xe Graphics G7 as long as the title is not too demanding. Witcher 3, for example, runs smoothly at around 50 fps in the medium preset and the performance is also steady (except for one small outlier). The corresponding core clock is ~1000 MHz and the CPU runs with ~1.3 GHz on average (the CPU load is not very high in Witcher 3). The overall power consumption of the processor is little more than 16W. Please see our tech section for more gaming benchmarks of the Xe Graphics G7.

Emissions - X1 Nano with good thermal management

System Noise

The cooling performance with a single fan and a long heat pipe.
The cooling performance with a single fan and a long heat pipe.

The cooling solution is interesting, because Lenovo uses an unusually long heat pipe across the whole chassis. The single fan dissipates the warm air at the right side of the chassis. The X1 Nano is a very quiet device in everyday scenarios and short peak load can usually be compensated without noticing the fan. If the fan is running, the noise is not high-pitched. Medium workloads (like 3DMark 06 or Witcher 3) result in 34.3 dB(A); more CPU load results in the maximum fan noise of 37.5 dB(A). However, this value will drop to 34.3 dB(A) under sustained workloads when the TDP drops.

We did not hear any electronic noises or coil whine during our review.

Temperature

Stress test
Stress test

The device hardly warms up at all while idling or under light workloads and stays slightly above room temperature. We can see two hotspots under load, one at the position of the processor and also at the fan exhaust. But all the temperature measurements stay well below 50 °C even under maximum load. Only one spot at the bottom shows more than 45 °C, and the keyboard stays cooler at up to 42 °C. You will notice these temperatures when you type, but there are no limitations.

The power consumption is 40W at the beginning of the stress test, but levels off at around 19W (similar to pure CPU load). Both components get roughly the same power in this scenario; the processor runs at 4x 1.3 GHz and the iGPU at 700 MHz. The performance is not reduced immediately after the stress test.

Speakers - Dolby Atmos in the X1 Nano

Similar to the bigger ThinkPad X1 Carbon, the X1 Nano gets a total of four speakers (2x 2W woofers at the front of the base unit + 2x 1W tweeters above the keyboard), which are higher rated than the X1 Carbon G8 (2x 0.8W tweeters). A direct comparison between the two, however, reveals that the sound of the X1 Nano is not quite as rich. The speakers also tend to distort a little bit more at speaker settings of more than 60 %. It is still a good setup that easily beat typical ThinkPad speakers like on the ThinkPad X13. The maximum volume of more than 85 dB(A) is also pretty high.

The X1 Nano is very close to the Dell XPS 13, only the MacBook Air is better across the dynamic range and stays the benchmark in this category.

The preinstalled Dolby Atmos software includes several profiles, which have a noticeable effect on the sound. You can either let the software decide automatically based on the content or select a preset manually (like movie, music, communication). We did like communication, where voices are clearly enhanced.

Compact 65W power adapter (323 grams)

The X1 Nano performs well in our consumption measurements, but it does not set any highlights. We recommend avoiding the maximum keyboard illumination on battery power, because it increases the consumption by 2.2W; the first stage is much more efficient at +0.5W.

The maximum consumption under load is 57W for the whole system, but this value levels off at around 27W after a few minutes. The provided 65W power adapter, which was introduced with the ThinkPad X1 Carbon G8), is therefore completely sufficient.

Battery Runtime

Lenovo implements a 48.2 Wh battery, which is the smallest capacity in our comparison group together with the ThinkPad X13. The battery runtimes are decent, but the difference between the Wi-Fi test (~10 hours) and the video test (~15 hours) at 150 nits each is pretty substantial. We repeated the tests, but the results did not change. We have also performed the Wi-Fi test with the enabled Windows power saver mode, which improved the runtime by around 1 hour. We also checked the battery runtime with the integrated LTE module and summarized the results in the following table:

Runtimes Wi-Fi test
Wi-Fi Test (default) Wi-Fi Test (Power Saver) Wi-Fi Test (max. brightness) Wi-Fi Test (LTE) Wi-Fi Test (LTE, max. brightness)
9:56 h 11:10 h 8:23 h 9:38 h 7:37 h

All the rivals (especially the MacBook Air M1) except for the ThinkPad X13 manage better results. We already said the performance is not reduced on battery power, which explains the comparatively short minimum runtime of 98 minutes.

The X1 Nano supports Rapid Charge and Lenovo advertises 80 % of the capacity after a charging time of 60 minutes. We can confirm this value, because we recorded 62 minutes for 80 % when the device was turned on; 50 % is available after 36 minutes. The charging curve flattens significantly after 80 %, and the remaining 20 % take more than one hour.
