Lenovo Legion 5 15IMH05H Review: Excellent power delivery and good battery life

Core i5 turns on. The Legion displays all games smoothly on its matte 15.6-inch display (120 Hz FHD, IPS). The integrated GPU is activated as a standard but can be deactivated with the click of a button. The battery life is very good as well.
Sascha Mölck, 👁 Sebastian Jentsch, Felicitas Krohn (translated by Katherine Bodner),

The Lenovo Legion 5 15IMH05H is an upper mid-range 15.6-inch gaming notebook. It is the successor of theLenovo Legion Y540-15IRH Laptop Review: A good gaming laptop with a GeForce GTX 1660 Ti GPU Legion Y540-15IRH and still resembles this device, although the build is not exactly the same. Our test configuration is equipped with a Core-i5-10300H and a GeForce-RTX-2060. Among its competitors are devices such as the Dell G5 15 SE, the Asus TUF A15 FA506IV and the MSI Alpha 15 A3DDK-034.

Case - Lenovo uses black plastic

The case of the Legion is entirely made of black plastic (Phantom Black), with a rubberized surface on the top of the base unit. The most noticeable aspect of the device is the way the lid is connected to the base unit, as the hinges have been shifted towards the front by 25 mm (~0.98 in). The battery is firmly built in and there is no maintenance hatch. The notebook will look familiar to users who know the Lenovo gaming series - although there are some differences to the predecessor Legion Y540-15IRH

The workmanship of the notebook is good. The gap dimensions are regular and we did not notice any overhanging material. Unfortunately, the device is not quite as sturdy as we would have hoped. The base unit can only be warped slightly, but it can be compressed on the right and left side of the keyboard without a lot of pressure. The lid can be warped considerably, which we are rather disappointed by. Pressure on the back of the display causes the image to change in a few areas. The hinges are tight and keep the lid in position while still enabling users to open the device with one hand.

There is not a big difference between the dimensions of the various devices, although the Legion is the heaviest notebook with a weight of 2.5 kg (~5.5 lb).

Connectivity - No Thunderbolt 3 for this Lenovo

The Lenovo offers no surprises in terms of port selection. The device has four USB ports (3x Type A, 1x Type C), which all support the USB 3.2 Gen 1 standard. In addition, the Type C port supports the DisplayPort via USB-C function (although users will have to buy a separate adapter to make use of it). We would have appreciated a Thunderbolt 3 port and also noticed that the Legion doesn't offer an SD card reader.

The ports are spread across three sides. The ports on the left and right are positioned in the middle, which leaves sufficient free space around the wrist rests.

Communication

The included Wi-Fi module (Intel Wi-Fi 6 AX201) supports the fast ax standard. We tested it under ideal conditions (no other Wi-Fi devices in the vicinity, short distance between notebook and server PC) and the transfer rates were very good. The Legion also has a Gigabit Ethernet controller from Realtek's RTL 8168/8111 series, which works reliably.

Webcam

The webcam (0.9 MP) of the Legion 5 creates washed-out images with a maximum resolution of 1280x720 pixels. Colors are not displayed particularly accurately either - we measured a Delta E deviation of 25, which is very far from the ideal of below 3.

Accessories

The notebook is delivered with the usual paperwork: a quick start guide and warranty information.

Maintenance

The Lenovo notebook does not have a maintenance hatch. Users will have to remove the base cover to get to the insides, which can be done by removing all the screws and lifting the cover off with the help of a spatula or a similar flat tool. This is more difficult on the back of the base unit - you will have to work carefully.

Input Devices - crisp keyboard with backlighting

Keyboard

The Legion is equipped with a backlit chicklet keyboard. Its concave keys have short travel and a clear pressure point. We were also pleased with the crisp actuation. The keyboard hardly gives way while typing and this certainly wasn't an issue. The backlighting (two brightness levels) can be controlled via a function key. Overall, this is a good keyboard suitable for everyday use. 

Touchpad

The multi-touch ClickPad takes up around 10.6 x 7 cm (~4.17 x 2.75 in). It therefore offers sufficient space for gesture control. The smooth surface of the pad makes it easy for fingers to glide over. It responds to inputs nicely - even in the corners - has short travel and a clear (and audible) pressure point.

Display - 120-Hz IPS

The 15.6-inch panel in the Legion has a native resolution of 1920x1080 pixels. While it has a good contrast ratio (1158:1), its maximum brightness is too low at 277.3 cd/m². We usually consider values above 300 cd/m² and 1000:1 as good. The response rate is fine for a 120-Hz panel. We were pleased to see no PWM on this screen.

* ... smaller is better

The screen has decent colors ex-works, although its DeltaE 2000 deviation of around 5 isn't within the ideal range (DeltaE below 3). The display does not suffer from a blue cast. Our calibration improves color display slightly, but the color spaces AdobeRGB and sRGB aren't covered entirely (37 and 57 percent, respectively).

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
17 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 9 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 21 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
26 ms ... rise ↗ and fall ↘ combined↗ 12 ms rise
↘ 14 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 636 (maximum) ms. » 18 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (38.7 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17520 (minimum: 5 - maximum: 2500000) Hz was measured.

The notebook is equipped with an IPS panel with stable viewing angles. This means that the screen can be read from any angle. Using the device outside is only possible if the sun isn't shining too bright.

Testing Conditions

The preinstalled Lenovo Vantage software enables users to set a temperature mode. There are three modes available: performance mode, balanced mode and calm mode. We ran all benchmarks in performance mode.

In order to get an idea of how these settings influence performance, we also ran some benchmarks in all three modes, in which case we mention these results explicitly.

Users can switch the integrated UHD Graphics 630 on and off within the BIOS or using the Lenovo Vantage software (Hybrid mode). As the GPU is activated ex-works, we ran our tests with the iGPU (and therefore the graphics switching function Optimus) activated.

Processor

Lenovo has equipped the Legion with a quad-core Core-i5-10300H processor (Comet Lake). The CPU clocks at a base rate of 2.5 GHz. The clock rate can be boosted to 4.2 GHz (four cores) and up to 4.5 GHz (one core). Hyperthreading (working two threads per core) is supported.

The multi-thread tests of the Cinebench benchmarks are processed at 4.2 GHz (on mains) and 2.5 GHz (on battery). The single thread tests are worked at 4.2 - 4.5 GHz (mains) and 3.5 - 4.2 GHz (battery).Intel Core i5-10300H SoC - Benchmarks and Specs

Single thread (battery)

To find out whether the CPU turbo is available for a prolonged period on mains, we run the multi thread Cinebench R15 benchmark in a loop for at least 30 minutes. The results remain constant throughout the test, which means that the turbo continues to be used to the maximum.

The temperature modes that can be set within Lenovo Vantage have a strong influence on performance. The CB15 loop in balanced or calm mode results in 530 and 540 points in the first two rounds, but the results subsequently drop significantly in calm mode. The balanced results are more or less on par with those recorded in performance mode.

The modes influence single thread performance as well with the single thread test of the CB15 benchmark resulting in 131 points (balanced mode) and 108 points (calm mode).

Storage Devices

Our test unit is equipped with an NVMe SSD (M.2 2242) from Samsung, with a capacity of 512 GB. The transfer rates are very good.

The notebook also has a slot available for a 2.5-inch storage device (SATA slot plus caddy included) or a second NVMe SSD (M.2-2280). Both devices cannot be operated simultaneously as you will need to remove the 2.5-inch caddy to insert the second NVMe SSD.

GPU Performance

The GeForce RTX-2060 (Turing) is a top-range GPU that supports DirectX 12 and clocks at a base rate of 960 MHz, which can be increased to up to 1200 MHz via the turbo boost. Provided the GPU does not reach a certain temperature or energy limit, it can reach even higher speeds. We actually measured a maximum clock rate of 1931 MHz. The Witcher 3 test was completed with an average speed of 1511 MHz. The GPU can make use of fast GDDR6 storage (6144 MB).

The results of the various 3DMark benchmarks are as expected for this GPU. The integrated Intel GPU UHD-Graphics-G1 is active and the notebook uses Nvidia Optimus to switch between the two. As mentioned earlier, the iGPU can be deactivated in the BIOS or using Lenovo Vantage.

The temperature modes of the Lenovo Vantage software have an influence on the graphics performance. While the 3DMark results in performance and balanced mode are very similar, the graphics performance drops significantly when calm mode is active.

Gaming Performance

The CPU/GPU combination of the Legion 5 displays all games smoothly at Full-HD resolution and high to maximum quality settings. The GPU even manages some resolutions above Full-HD (this would require a suitable external monitor), although you would have to lower the quality settings slightly to get there.
