Lenovo ThinkPad X13 G4 Intel Laptop Review: Compact 5G traveler with OLED
Lenovo's ThinkPad X series are traditionally the most compact and lightweight laptop models of the classic enterprise ThinkPads. The Lenovo ThinkPad X13 Gen 4 is the newest model of the line, which spawned popular models like the ThinkPad X220 in the past, but nowadays feels a bit lost between the X1 and ThinkPad T series. Is the traditional subnotebook over? Maybe not quite yet, as Lenovo still invests into the line, upgrading the X13 Gen 4 with the newest CPUs and a new design as well.

Chassis: modernised design close to the ThinkPad X1 Carbon
Two years ago, the ThinkPad X13 Gen 2 is one of the first ThinkPad laptops with the then new design language, including the new dark grey chassis color "thunder black". This year, the ThinkPad X series again plays the role of the avant-garde, but at least in terms of the color it is "back to the future": The color is "deep black" now instead of "thunder black. Part of the new design features, which probably will make it into other future ThinkPads, is the "reverse notch" for the webcam, which is placed prominentely on the lid. This design is divisive, but it does serve as a practical handle for opening the screen.
The lower part of the chassis is made out of metal, aluminum is used for the base plate and magnesium for the palmrest. The screen cover is made out of Carbon fiber plastic. The stability of the base and the workmanship is perfect, but this is not quite true for the screen cover. It is slightly bendable and produces a few faint creak noises. A magnesium cover like with the ThinkPad X13 Yoga G4 would have been a better choice for stability. As with the X13 Yoga G4, the black rubberized paint feels high quality, but it gets dirty fast.
The screen can not be opened with one hand. The maximum opening angle of 180 degrees is made possible by the two small drop down hinges, which hold the screen in place firmly.
Lenovo has reduced the weight and size of the ThinkPad X13 G4 compared with the predecessor, with the volume of the X ThinkPad going down from 1.25 to 1.03 liter in comparison with the ThinkPad X13 G3.
Compared with the HP and Dell subnotebooks, the X13 Gen 4 is thinner and lighter than the HP EliteBook 835 G9 and thinner than the Dell Latitude 7340 - which on the other hand is more lightweight and smaller.
Connectivity: ThinkPad X13 Gen 4 with 5G
Nice: The fan outlet has been moved from the side to the back. Mouse users will not have to worry about the stream of warm air anymore. Otherwise, Lenovo does not change much about the port selection, which is up to the usual business laptop standard and generous for a compact 13.3 inch laptop, with HDMI and USB A. Dongle life is not a thing for ThinkPad X13 users.
Communication
Apart from the Intel AX211, a WiFi 6E module, which delivers fast transfer speeds in the Lenovo ThinkPad X13 Gen 4, Lenovo puts in another network module: The Fibocom FM350-GL, a Sub6 5G module. This makes this model variant ideal for frequent business travelers. Alternatively, the X13 G4 is available with normal LTE cards or without any WWAN module as well.
Webcam
Like with most of the mid-tier to premium ThinkPad laptops of the 2023 generation, Lenovo puts a 5 Megapixel webcam into the ThinkPad X13 Gen 4. The quality is improved compared with the 1080p cam of the predecessors, but still far from being actually good.
Security
With a Kensington lock, dTPM and Smartcard reader, the Lenovo ThinkPad X13 Gen 4 has pretty much the whole array of enterprise security features. Additionally, there is a fingerprint reader in the power button and an IR camera next to the webcam for fast log in, as well as the "ThinkShutter", a mechanical camera shutter for better privacy.
Accessories
Apart from the 65 W GaN charger, there are no additional accessories in the box.
Maintenance
The bottom cover of the Lenovo ThinkPad X13 Gen 4 is easily removable, as there are only five screws and a few clips at the back that need to be opened. The screws are captive, so they can not be lost.
RAM and WiFi module are soldered, WWAN card and M.2 2280 SSD are modular. The screwed in battery can easily be changed and the fan cleaned. The keyboard on the other hand is not user replaceable anymore, different from the ThinkPad X13 Gen 3.
Warranty
Lenovo gives the ThinkPad X13 Gen 4 three years warrantry, with Premier support and on-site service for the first year. The battery gets a one year warranty as well. For the remaining two years, there is a bring in service, which can be upgrade to Premier support if the user so wishes.
The Lenovo warranty is valid internationally as well, though outside of the country of origin (in this case, Germany), Lenovo only provides bring in service.
Input devices: Same keyboard as in the X13 Yoga Gen 4
Input devices are identical to the Lenovo ThinkPad X13 Yoga Gen 4, which is why we will not decribe the backlit keyboard, touchpad and TrackPoint again. All three input devices are easy and comfortable to use and they make the Lenovo ThinkPad into a great work device. Small point of criticism: The touchpad is smallish.
Display: OLED for the first time in the classic ThinkPad X
Lenovo offers the ThinkPad X13 Gen 4 Intel with a total of four different display options. All share the screen aspect ratio of 16:10 as well the screen size of 13.3 inches:
- WUXGA (1,920 x 1,200), IPS, 300 cd/m², 100 % sRGB, matt
- WUXGA (1,920 x 1,200), IPS, 300 cd/m², 100 % sRGB, matt, On-Cell Touch
- WUXGA (1,920 x 1,200), IPS, 400 cd/m², 100 % sRGB, matt, Low Power
- 2.8K (2,880 x 1,800), OLED, 400 cd/m², 100 % DCI P3, semi-glossy
The ThinkPad X13 Gen 4 is the first regular laptop model of the ThinkPad X series with an OLED screen. The organic screen does not reach the 400 cd/m², we measure 385 cd/m². Brightness is distributed extremely equally and typical for an OLED screen is the high contrast, since the black value sits at 0.0. IPS LCDs can not do this, but they can deliver a much higher brightness. An example is the HP EliteBook 835 G9.
Another advantage of OLED are the low response times, none of the IPS competition reaches the ThinkPad X13 G4 in this aspect.

Even with a calibration, it is difficult to set the panel to be accurate with the sRGB gamut, as the average Calman Colorchecker deltaE of 4.6 is rather high after calibration with the X-Rite i1 Pro 2 and i1Profiler.
The color gamut coverage of the screen is excellent, sRGB and DCI P3 are completely covered. Even the big AdobeRGB gamut has a coverage of 96 percent.
The screen has a semi-glossy surface, so reflections are going to happen. This makes outdoor usage not idea, though at least the high contrast of the panel helps with visibility. As long as users avoid direct sunlight, the X13 G4 is usable out of the office.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 60 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 60 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 60 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||
As usual with OLED screens, this one uses Pulse Width Modulation (PWM) to regulate brightness. It has two settings: From full brightness to 6/10 brightness, there is a PWM frequency of 60 Hz. Brightness of 5/10 or lower, the frequency increases to 240 Hz. People sensitive to PWM should avoid this Samsung OLED panel.
Performance: Raptor Lake without power in the X13 G4
Lenovo offers the ThinkPad X13 Gen 4 with the whole palette of recent Raptor Lake U15 CPUs: Intel Core i3-1315U, i5-1335U, i5-1345U, i7-1355U sowie i7-1365U. Exclusively for large business customers only as a special bid option, Lenovo also offers P28 CPUs (i5-1340P, i5-1350P, i7-1360P und i7-1370P) - consumers will not be able to get those CPUs. This was different for the preceding model.
Customers get the choice of Iris Xe with 80 or 96 EUs, depending on the choice of i5 or i7 CPU. The RAM is always soldered on-board, with 8, 16 or 32 GB LPDDR5-4800 memory. In terms of mass storage, the manufacturer offers a single M.2 2280 SSD with up to two terabyte ex factory.
Testing conditions
Customers do not have to contend with proprietary software to set the energy profiles. Instead, the Windows settings are used:
- Best battery life: PL1 11 Watt, PL2 11 Watt
- Balanced: PL1 12 Watt, PL2 35 Watt
- Best performance: PL1 15 Watt, PL2 50 Watt
Power Limit 1 is the power consumption under sustained load, Power Limit 2 is the maximum consumption for short term load.
As with the ThinkPad X13 Yoga Gen 4, the ThinkPad X13 Gen 4 has two possible cooling solutions: The U15 CPUs have one fan, the P28 processors have two. Since the P28 CPUs are limited to large business customers, such models will be rarely encountered.
Processor
The Intel Core i7-1365U is a U15 processor of the Raptor Lake series from Intel with ten cores: Two P cores (1.8 to 5.2 GHz) and eight E cores (1.3 to 3.9 GHz). Comparisons with other processors can be realised with our CPU comparison list.
With the limitation to 15 W under load, the CPU performance stagnates at the level of the i5-equipped predecessor. Overall, we found the X13 Gen 4 Intel to be disappointing, it only delivered a convincing single core performance and short term boost performance - the same CPU in the ThinkPad X1 Carbon G11 is faster. We expect a much better multicore performance from the ThinkPad X13 Gen 4 AMD.
In battery usage, we did not detect any CPU performance limitation.

DPC latency
The ThinkPad X13 Gen 4 Intel has problems with high LatencyMon values, which can lead to interuptions during audio/video work. This does not seem to be a dramatic problem though, as there would have been more skipped images during the Youtube test otherwise. Also, this situation can change fast with driver updates.
