Lenovo ThinkPad T14s Gen 6 (14 Snapdragon) review – AI Powerhouse with Epic Battery Life
Right now, Copilot+ PCs aren’t a rare find. The ThinkPad T14s Gen 6 (14″ Snapdragon) is one of them and it’s offered with Snapdragon X Elite X1E-78-100 or Snapdragon X Plus X1P-42-100 processor. These are a good choice for people who need top-of-the-line AI performance thanks to the Qualcomm Hexagon NPU with up to 45 TOPS.
Aside from that, the rest of the specs are more or less normal for a modern small machine like this one. It’s full of useful extras such as Wi-Fi 7, hardware-ready Bluetooth 5.4, a backlit keyboard, and a battery with a modest capacity. The security features seem more than good because of the self-healing BIOS, the IR Web camera with a privacy shutter, the fingerprint reader, and the dTPM 2.0 + Microsoft Pluton TPM 2.0. The eSIM functionality is optional.
There are three display options, two 1200p 60Hz units (one of them is a touchscreen) and a 120Hz 2.8K (2880×1800) OLED with HDR capabilities.

What’s in the box?
In the box, you’ll find a bit of paperwork and a 65W USB Type-C adapter.
Design and construction
When it comes to design, the ThinkPad T14s Gen 6 (14″ Snapdragon) looks like a slightly evolved version of the Intel-based T14s Gen 4. That’s mainly because of the protrusion on top for easier opening and the narrow bezels. The lid is made of carbon-fiber-reinforced polymer and the base is aluminum. The chassis is solid which is nice to see.
The hinges aren’t the stiffest we’ve seen but you can’t open the laptop with one hand. Still, this gadget weighs just 1.24 kilos and has a profile thickness of just 16.9 mm. Yep, the portability seems great!
The bezels around the 16:10 display are narrow-ish.
The “hump” in the middle of the upper bezel houses a 1080p IR Web camera for Windows Hello.
Fully flat opening is possible.
The spill-resistant backlit keyboard is great for typing. The key travel and the feedback are surprisingly good given the thin chassis. The board also has a Copilot shortcut, a TrackPoint, and decently-sized Arrows which are comfortable for usage. The touchpad size is adequate considering the small form factor. The pad is almost glass-like smooth and the accuracy feels fine. The only con here is the noisy clicks.
Nothing fancy on the bottom panel – two ventilation grills above the cooling, three rubber feet, and an emergency reset hole. The heat is being exhausted through a vent on the rear. Yes, some amount of hot air reaches the display during heavy CPU stress.
Ports
On the left, you get two 40 Gbps Thunderbolt 4 / USB 4 ports (both support data transfer, Power Delivery 3.0, and DisplayPort 1.4a), an HDMI 2.1 port (for up to 4K@60Hz external displays), and an Audio jack. On the right side, we can spot a Kensington Nano security lock slot, and a pair of 5 Gbps USB Type-A 3.2 (Gen. 1) ports (the former comes with an Always On function). Some machines have a Nano-SIM card slot on the same side but our laptop doesn’t.

Viewing Angles
Viewing angles are good. We take photos from different angles to evaluate the quality.
Also, a video with locked focus and exposure.
Color Coverage
The whole “sail-shaped” map below (Fig. 1) consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.
Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon) can show:
Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content
Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon): the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display.
In our tests, we calculated the total color coverage of the monitor at 50% of the sRGB color gamut and 40% of the DCI-P3 color gamut.
(Fig.1) Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon) covers 50% of the sRGB gamut
Brightness and Contrast
The maximum brightness in SDR mode is 400 cd/m² in the center of the screen and 393 cd/m² averaged across the surface with a maximum deviation of 8%.
The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6500K.
The contrast ratio is 1040:1.
Uniformity: Luminance, Contrast, and Color Deviation
The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 180 nits (Windows slider = 70%) — a brightness level we consider typical for standard working conditions.
DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.
Color Accuracy
Let’s check the difference between real colors and those you’ll see on the Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon). We measure that distance in DeltaE – the higher the number, the more different they look.
Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.
For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.
Before our calibration of the Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon), the Average color accuracy was 5.2 dE (Fig. 2), and with our Design and Gaming profile, it lowered to 4.6 dE (Fig. 3).

Visibility in dark scenes
Have you ever watched a movie with dark scenes where you could barely see anything? This often happens because many display panels struggle to differentiate the darkest nuances, making them appear the same.
The next figure illustrates how well the display reproduces these dark nuances. The left side of the image shows the display with stock settings, and the right side shows it with our Design and Gaming profile activated.
On the horizontal axis are the grayscale levels, and on the vertical axis – the corresponding display brightness.
You can also check how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 19.5 ms. Short pixel response time is a prerequisite for a smooth picture in dynamic scenes.
After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.
Health Impact: PWM (Screen flickering)
Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.
In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.
The light from the backlight of the Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon) display is not pulse-width modulated, providing visual comfort in the discussed aspect.
Health Impact: Blue light emissions
Installing our Health-Guard profile not only eliminates harmful PWM when the laptop uses it to control brightness but also reduces harmful Blue Light emissions while keeping the colors of the screen perceptually accurate.
If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.
Health Impact: Screen Reflectance
Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.
The reflectance of the Lenovo’s screen is 54.6 GU.
High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.
Office Work
Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.
Design and Gaming
This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.
Health-Guard
Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.
Average core frequency
| Qualcomm Snapdragon X Elite X1E-78-100 (35W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| ThinkPad T14s Gen 6 (14″ Snapdragon) | 3.42 GHz | 3.39 GHz | 1.67 GHz |
| ASUS Vivobook S 15 OLED S5507 | 3.40 GHz | 3.40 GHz | 3.40 GHz |
The Snapdragon X Elite X1E-78-100 inside the ThinkPad T14s can sustain the same clocks (~3.40 GHz) in short and medium loads as the much bigger ASUS S5507. Unfortunately, in longer stress, the frequencies are halved.
Comfort during full load
The fan is audible but not noisy during max CPU loads in “Best performance” mode.
The hotspot on the keyboard reaches 48°C and the zone above it is 2°C warmer. Still, the board steel feels warm, not hot.
In long max loads, the CPU can sustain 1.67 GHz in “Best performance” and “Balanced” modes. The latter offers less aggressive fan speed which is good. If you apply the “Best Power Efficiency” preset, you can expect just a 710MHz processor clock.
“Best Performance”
“Balanced”
“Best Power Efficiency”Battery
Now, we conduct the battery tests with the Windows Best Power Efficiency setting turned on, screen brightness adjusted to 180 nits and all other programs turned off except for the one we are testing the notebook with. The 58Wh battery lasts for around 19 hours and a half of video playback. That’s a great result! To achieve that, you have to apply the “Energy Saver” preset in the Windows “Power & Battery” menu.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
Disassembly, Upgrade options, and Maintenance
To open this compact notebook, you have to undo just five captive Phillips-head screws. Pop the top two edges with a thin plastic tool. After that, pry the sides and the front. Once you’ve finished that, you can raise the back.
Here’s how the bottom panel looks on the inside.
This notebook is equipped with a 58Wh battery. To take it out, pull up the connector from the motherboard and undo the three Phillips-head screws that fix the unit to the base. The capacity is enough for around 19 hours and a half of video playback.
There is a mylar film over the heat spreader.
Expectedly, this Snapdragon device has a soldered memory. You get up to 64GB of LPDDR5x-8533MHz RAM that runs at 8448MHz due to platform limitations. The machines with eSIM functionality have a WWAN slot that is placed on the left of the cooling. As you can see, our laptop lacks this feature. The Wi-Fi card is also soldered.
In terms of storage, you can rely on a single M.2 slot compatible with 2242 Gen 4 SSDs. The NVMe drive is protected by a metal cap that is held in place by two screws. The shroud houses a thermal pad on its bottom side. We found another pad below the SSD.
The cooling has one decently-sized fan, a long heat pipe, a heat sink, and a sizable heat spreader.
Verdict
The Lenovo ThinkPad T14s Gen 6 (14″ Snapdragon) is a well-built machine that could be a dream come true for professionals on the go who need a good AI performance. In addition to that, the battery has enough juice for almost 20 hours of videos despite the modest 58Wh capacity. This laptop’s adequate input devices and nice comfort under load, make it an ideal portable machine.
The 1200p IPS touchscreen (NV140WUM-T08 (LEN403D)) is PWM-free, has wide viewing angles, and 400 nits of max brightness. That’s all you need for normal home or office work. If you want better color coverage, the optional 2.8K OLED unit will do the job if money isn’t a problem.
Since there is a Snapdragon SoC under the bonnet, it’s not a secret that the upgradability is limited. You can change the NVMe drive, that’s all. The port selection is up to date thanks to the pair of Thunderbolt 4 connectors.
The ThinkPad T14s Gen 6 could impress future buyers with its powerful NPU chip, long battery life, solid build, and comfortable keyboard.
