Lenovo Googlebook 15 Review - Pretty underwhelming

Mediocre.

Lenovo offers a 15-inch Googlebook with an Intel Panther Lake CPU as well as a 2.8K OLED screen. However, the hardware is pretty mediocre in addition to the software limitations, which makes this Googlebook 15 the worst one we have tested so far.

Verdict - Lenovo Googlebook 15 disappoints

Our impression of the new Lenovo Googlebook 15 is pretty sobering. We already tested two Googlebooks before, which featured premium cases in a 14-inch form factor, but Lenovo's larger 15-inch model feels like a pretty cheap device. The smooth surfaces simply feel like plastic, the hinges are wobbly and the keyboard is a bit disappointing. The only two advantages are the haptic trackpad as well as the low weight of ~1.3 kg. You also get Wi-Fi 7 as well as Thunderbolt 4, even though it does not really make a difference since Googlebook OS is simply a limiting factor. The Intel Core Ultra 5 CPU also provides plenty of performance considering you can only run Android apps (and there are still compatibility issues). Due to the high short-term power limit (which is unnecessary in our opinion), the fan is more active compared to the other Googlebooks.

You can replace the M.2-2242 SSD and the sound system is really good. You also get a good OLED screen with accurate colors and HDR support, but Googlebook OS is once again a limitation because it only runs in sRGB mode. We already know this issue and hope Google will fix this problem soon. All in all, the Lenovo Googlebook 15 is a pretty underwhelming product and considering all the limitations as well as the price, we really don't know why you would buy this instead of a Windows system or a MacBook Air.

Pros

+ lightweight chassis
+ decent system performance
+ Wi-Fi 7 and Thunderbolt
+ excellent sound system
+ 120 Hz OLED with good image quality and accurate colors, but...

Cons

- ...limited to sRGB
- PWM flickering
- limited to Android apps (and some don't work)
- soldered RAM
- wobbly hinges
- no 5G/LTE support

Case, Connectivity and Input Devices

Lenovo uses a light grey (almost white) chassis for the Googlebook 15 and the initial impression is not great, because it feels like a pretty cheap plastic chassis with smooth surfaces. The lid in particular is a weak spot. The spec sheet reveals that it is partly made of metal, which surprised us. The device is pretty light at ~1.3 kg, which is an advantage. The stability of the base unit is okay, but the hinges are pretty wobbly. You also get the glow bar on the lid, but it is pretty useless because you simply cannot see it. All in all, this is simply not a premium case as we have seen on other Googlebooks so far (from Asus and HP).

Maintenance options are limited to the battery, the single fan as well as the compact M.2-2242 SSD. Connectivity is good with two Thunderbolt 4 ports, USB-A as well as HDMI. Wi-Fi 7 is supported and you get a decent 5 MP webcam.

There is also a power button on the right side, which is surprising considering you get a dedicated fingerprint scanner button in the top right of the keyboard, which usually acts as a power button. The keyboard is also pretty mediocre and comparable to cheaper IdeaPad models. The key travel is pretty shallow at 1.3 mm and the white illumination is an issue, because there is simply not much contrast compared to the light grey key caps unless the environment is completely dark. The large haptic touchpad, however, works very well. Lenovo also offers a corresponding AI mouse with a magic cursor, which works well.

Display - 2.8K OLED with 120 Hz

Subpixel array
Subpixel array

Lenovo uses a 15.3-inch OLED panel with a resolution of 2880 x 1800 pixels and a frequency of 120 Hz. The subjective image quality of the glossy screen is very good with deep blacks and rich colors. However, the color management of Googlebook OS is still problematic. While we did not experience the black value issue of the Asus Googlebook 14 or the HDR issues of the HP Googlebook 14c, the panel is once again limited to sRGB, even though the specs clearly state P3 color gamut. This seems to be a general issue with Googlebook OS, but the color accuracy is at least pretty accurate in our analysis with the professional CalMAN software for sRGB and you can edit pictures or videos.

The brightness values are excellent with 500 nits for SDR contents and up to 1117 nits peak HDR brightness (702 nits for a completely white image), so media playback looks great on this OLED panel. Response times are very fast and the PWM frequency is very high at 1.2 kHz with a pretty small amplitude, so the flickering should not be an issue for most users.

Display Response Times

ℹ
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
0.46 ms ... rise ↗ and fall ↘ combined↗ 0.25 ms rise
↘ 0.21 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 0.1 (minimum) to 240 (maximum) ms. » 1 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (19.6 ms).

This means that the measured response time is better than the average of all tested devices (30.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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 1200 Hz
Amplitude: 33 %
≤ 99 cd/m² brightness

The display backlight flickers at 1200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 cd/m² and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1200 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 7567 (minimum: 5 - maximum: 343500) Hz was measured.

Performance - Intel Panther Lake

Lenovo uses an Intel Panther Lake Core Ultra 5 325 CPU in combination with 16 GB RAM, which cannot be upgraded and there are no other CPU/memory configurations available. Considering the fact that you are limited to Android apps anyway, the performance is more than sufficient and the Googlebook 15 is a responsive laptop. We did not experience any stability issues, either, but we still had issues with some Android apps that simply did not work on the Googlebook, including benchmarks like CrossMark or popular games like PUBG and Fortnite. We recommend streaming services like GeForce Now if you also want to play games on your Googlebook.

Based on our power measurements, the short-term power limit for the Core Ultra 5 325 should be around 45 Watts, but it quickly drops to ~20 Watts after a couple of seconds. The initial value is way too high in our opinion and simply results in more fan activity. You also get the Panther Lake iGPU with 4 Xe cores as well as a 512 GB PCIe 4.0 SSD from Kioxia (EG7, 476 GB free after initial set-up).

Emissions & Power Consumption

System Noise

Cooling unit
Cooling unit

The Lenovo Googlebook 15 uses a single fan and while the overall noise levels are pretty low, the fan activity is noticeably higher compared to the other Googlebooks from Asus and HP we have tested before, which is a bit surprising considering the larger chassis. The fan will often start spinning even during light workloads, which surprised us. Compared to traditional Windows laptops, however, the laptop is still very quiet at up to ~34 dB(A). We did not hear any other electronic noises.

Power Consumption and Battery Life

Our review unit was not shipped with a power adapter and based on our measurements, we recommend a 65 W unit to be on the safe side. The maximum consumption can reach up to 57 Watts for a couple of seconds, but it quickly drops to around 33 Watts. The 70 Wh battery only manages mediocre runtimes: Our Wi-Fi test only ran for about 10.5 hours at 150 nits and almost 6 hours at full brightness.

Transparency

The selection of devices to be reviewed is made by our editorial team. The test sample was provided to the author as a loan by the manufacturer or retailer for the purpose of this review. The lender had no influence on this review, nor did the manufacturer receive a copy of this review before publication. There was no obligation to publish this review. As an independent media company, Notebookcheck is not subjected to the authority of manufacturers, retailers or publishers.

This is how Notebookcheck is testing

Every year, Notebookcheck independently reviews hundreds of laptops and smartphones using standardized procedures to ensure that all results are comparable. We have continuously developed our test methods for around 20 years and set industry standards in the process. In our test labs, high-quality measuring equipment is utilized by experienced technicians and editors. These tests involve a multi-stage validation process. Our complex rating system is based on hundreds of well-founded measurements and benchmarks, which maintains objectivity. Further information on our test methods can be found here.
