Lenovo Legion Phone Duel Smartphone Review- Gaming phone with 144 Hz screen

Consistently across. That Lenovo's Legion Phone Duel is a gaming smartphone is obvious at first glance. Thanks to the 144 Hz screen and extreme performance, it feels extremely smooth and the price is also convincing. However, there are also small flaws...

Case, features and operation - Unusual cell phone

In red or blue, but in any case with a very unusual chassis design, the Lenovo Legion Phone Duel comes to your home. Even the packaging is unusual: It consists of several triangles that you open to reveal the phone, accompanied by a machine sound that comes from a small speaker including a battery in the package. That is pretty cool, but of course questionable in terms of the environment.

The metal and glass chassis feels high-quality and refracts the light at the back, which looks good. The Legion lettering and the large logo in the center glow in different colors. The positioning of the main camera and the flash is unusual; both are in the center of the smartphone. However, this actually corresponds to the positioning of a conventional camera. Overall, it is noticeable that Lenovo has optimized the smartphone for a landscape orientation of the screen, and one of the two USB-C ports is located in the center of the long side.

The smartphone comes with either 12 or 16 GB of RAM and 256 or 512 GB of UFS 3.1 storage. This puts it on a similar level as Asus' ROG Phone 3; Samsung's Galaxy S21 Ultra cannot keep up here. 5G is installed, the audio signal is output via USB-C, and an adapter for 3.5 mm jacks is included in the smartphone.

WiFi 6 is also available, but the Legion Phone Duel ranks rather behind in the comparison. The Wi-Fi is not slow in our test with the reference router Netgear Nighthawk AX12, but it is a bit slower than in other smartphones in the price range.

The software is based on Android 10, but is specially adapted. It offers a very good user manual including videos, but it is not always perfectly translated and the security patches were completely outdated at the time of testing.

For real gamers, there are two touch-sensitive areas that can be used as shoulder keys that can be customized for different games. Physical buttons would have been more suitable here, but they serve their purpose.

There is a fingerprint sensor behind the screen. It is a bit far down for our taste, but it is reliable. It is not active when the screen is turned off, and you at least have to activate the always-on display. Thanks to the 144 Hz screen and the fast processor, the smartphone can be operated quickly and feels very responsive.

Cameras - High image quality

Recording front camera
Recording front camera

The rear camera offers two lenses: The main camera with 64 megapixels, which increases the light yield via pixel binning, but then also only takes pictures with 16 megapixels, and a wide-angle lens.

The photos of the main camera are rich in detail and colorful. However, there could be more detail in dark areas in low light and high contrasts. The sharpness also decreases slightly towards the edges.

Videos can be recorded in a maximum of 4K resolution. The picture quality is also convincing here. The autofocus reacts quickly and precisely, but the brightness adjustment could be a bit more elegant.

The front-facing camera extends centrally from the casing's long side, which is also unusual at first glance, but not that bad in everyday use. The camera also takes detailed pictures and has no problems with fine structures like hair.

Display - Fast and color-accurate

Subpixel recording
Subpixel recording

The screen's resolution of 2,340 x 1,080 pixels is usual, but 4K gaming is not possible. The brightness is solid, but lower than all comparison devices. The color reproduction is quite accurate; we measured in the "natural" color mode.

With its 144 Hz frame rate, the screen feels very smooth in operation and can reproduce scrolling well. Although not many games support such high frame rates yet, that should change in the near future and then you can get small advantages in fast shooters due to the fast screen.

The AMOLED screen flickers as usual at brightness levels below 100%, but the frequency is quite high.

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
6 ms ... rise ↗ and fall ↘ combined↗ 3 ms rise
↘ 3 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 5 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.3 ms).
       Response Time 50% Grey to 80% Grey
8 ms ... rise ↗ and fall ↘ combined↗ 5 ms rise
↘ 3 ms fall
The screen shows fast response rates in our tests and should be suited for gaming.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 7 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (38.5 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.
Screen flickering / PWM detected 833.3 Hz

The display backlight flickers at 833.3 Hz (Likely utilizing PWM) .

The frequency of 833.3 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9686 (minimum: 5 - maximum: 142900) Hz was measured.

Performance, emissions and battery life - Fast in everyday use and charging

Of course, you expect a lot of performance from a gaming smartphone in the first place, and thanks to the Snapdragon 865+, this is also given in Lenovo's Legion Phone Duel. The performance remains constant even under longer load, as the 3D Mark Wild Life stability score of 99.2% shows.

However, the smartphone gets quite warm during operation; we measured 45.7 °C. However, this warming cleverly occurs in the center of the smartphone, where the hands are not in landscape mode.

The stereo speakers of the Legion Phone Duel are directed to the front and get averagely loud. On maximum power, they seem a bit overpowered and emphasize trebles very strongly. At 3/4 of the maximum volume, the sound seems rounder overall. Overall, the speakers are OK, but there are definitely better systems in the high-end sector.

Lenovo has divided the battery into two parts. It has a total capacity of 5,000 mAh. This has the advantage that both batteries can be charged simultaneously via the two USB-C ports and the charger with two cables. Thus, the Legion Phone Duel achieves ingenious charging times: Approximately 40 minutes from 0 to 100%. If you do not have the charger at hand, you can of course only use one of the two USB-C ports, but both batteries are still charged. The smartphone lasted 14:11 hours in our Wi-Fi test. That is not a record, but quite good and much longer than Samsung's Galaxy S21 Ultra.

In review: Lenovo Legion Phone Duel. Test device provided by Lenovo Germany.
In review: Lenovo Legion Phone Duel. Test device provided by Lenovo Germany.

Lenovo's Legion Phone Duel is a good gaming smartphone that can actually be used very smoothly thanks to its 144 Hz display and is future-proof for games. The manufacturer often goes unusual ways, such as placing the camera in the center of the casing or the centrally extending front camera. However, after a short familiarization phase, we actually find these quite good.

Whether you like the case is a matter of taste, but it is certainly not restrained. It is stable and ergonomic. We also like the cameras. The picture quality is convincing and the front-facing camera takes good selfies. The battery life is good and the smartphone charges extremely fast thanks to the dualbattery and the dual charging port. However, the heavy charger has to be accepted in return.

Lenovo's Legion Phone Duel is a gaming phone with a fast screen, many clever details and a few minor flaws.

The screen could be brighter, but the display is convincing and the system's performance is also more than sufficient for current mobile games.

All in all, Lenovo has come up with some clever details, which makes the Legion Phone Duel appealing not only for gamers. In other areas, especially the localization of the software, the final touches are missing and Lenovo should urgently release a software update for the security patches.

When I was 12, the first computer came into the house and immediately I started tinkering around, taking it apart, getting new parts and replacing them - after all, there always had to be enough power for the current games. When I came to Notebookcheck in 2009, I was passionate about testing gaming notebooks. Since 2012, my attention has been focused on smartphones, tablets and future technologies.
