Lenovo IdeaPad Duet Chromebook 10 tablet review

Chrome-tablet hybrid. As a Chromebook convertible, the Duet wants to replace laptops and tablets in the budget entry-level segment. The following review will reveal the limitations that users have to put up with.
Klaus Hinum, 👁 Klaus Hinum, Katja Steyrleuthner (translated by Stephanie Chamberlain),

Lenovo offers the IdeaPad Duet as a small 2-in-1 laptop for only 329 Euros (~$389). Currently, you can only choose between two different versions in Germany, which only differ in the size of the storage space: 64 or 128 GB. We'll take a closer look at the smallest entry-level device with 64 GB of flash memory. The 128 GB variant currently costs only 20 Euros (~$24) more in Lenovo's online shop.

Case

The two-tone plastic and aluminum case is relatively clunky, but it pleases with a decent feel and stability. On our test device, the plastic part on the back is blue - a nice contrast.

The included stand is magnetically attached to the back and pleases with a nice fabric upper side. The metal hinge is relatively firm and stays in place in any adjusted position. Consequently, the Duet can be adapted to different requirements. How long the relatively delicate stand will last in daily use, however, is somewhat questionable. Furthermore, the keyboard cover is made of plastic; the backside feels like neoprene and is a bit susceptible to stains. But it can be easily cleaned with a damp cloth.

When using the stand and the keyboard, the Chromebook Duet becomes a clunky laptop. An iPad Pro with the keyboard cover is much thinner.

Connectivity

As is typical for tablets, the IdeaPad Duet isn't very generous when it comes to its port configuration, offering only a USB-C port and pogo pins to connect the keyboard. The USB-C port is used to charge the device and also to transfer data. Moreover, a headset can be connected with the included USB-C to 3.5 mm audio jack adapter. An external monitor can also be connected via USB-C (DisplayPort), but the resolution is limited to a very weak 1280x720.

Software

The IdeaPad Duet runs on Chrome OS and gets updates directly from Google. These updates are supposed to be guaranteed for 8 years, i.e. until June 2028, and thus for a significantly longer period than on Android and possibly iOS-based tablets.

Communication and GPS

GPS and LTE are not available despite the ARM-based MediaTek SoC, and WLAN and Bluetooth, unfortunately, don't offer the latest standards; users have to make do with Wi-Fi 5 and Bluetooth 4.2 here. As expected, the WLAN performance is not groundbreaking. Compared to the convertible competition (including high-end Windows devices), the 300 Mb/s observed in the test is only below average. But also more expensive Chromebooks like the Dell Inspiron 7486 or the Yoga Chromebook C630 are significantly faster.

In our practical test, however, the connection is stable and without limitations.

Cameras

In terms of cameras, Lenovo benefits from the MediaTek SoC with smartphone genes. As a result, you receive a rear-facing camera that is good for laptops and also at a low cost. If you compare the quality to other smartphones, however, you'll find the cameras to be in the entry-level range.

The front-facing camera only offers a 2 MP sensor and thus also a limited quality. It's definitely enough for a webcam, though.

Input devices and handling

The included detachable keyboard struggles most with the limited space. This causes the umlaut keys in the German version to shrink considerably. The stroke feels very cushioned but is also very quiet in return. The travel of the individual keys is clearly limited, but it's sufficient for us. In the practical test, you get used to the small keyboard relatively quickly, and you're able to type fluently. However, you won't reach any speed records, and it's not particularly enjoyable to type longer text with the keyboard cover.

There is a small ClickPad below the keyboard; we were able to use it surprisingly well in the test, and the integrated mouse button also pleases with a precise pressure point, which is quite remarkable for the price range.

The integrated multi-touch screen is very accurate in drawing programs and offers fast response times. Unfortunately, the relatively weak CPU doesn't always keep up with the amount of input, which can definitely cause delays when scrolling or using multi-touch zoom in menus, apps, and in the browser.

Display

The glossy 10.1-inch IPS display offers a high resolution of 1920x1200 pixels (>Full HD) in the 16:10 format. It pleases with its good quality. The viewing angles, color reproduction, and contrast are surprisingly good for its price range. Only the maximum brightness could be a bit higher so as to better be able to use the tablet outdoors in the sunlight. In comparison to the premium competition from Apple (iPad 7) and Microsoft (Surface Go), the good display can't keep up, unfortunately, and even the cheap Amazon Fire HD 10 tablet shows better values in some areas.

PWM and display flickering

We couldn't detect the classic PWM in the Duet; the brightness is controlled from 0 to 100 without PWM. When plugged in, however, we see a slight flickering on the measuring device at a high frequency between 59 and 65 kHz. This becomes much less on battery power, so this is probably due to nonideal shielding.

Response times are only mediocre for black-to-white and gray-to-gray transitions, but they're in the usual range for an IPS display.

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 17699 (minimum: 5 - maximum: 2500000) Hz was measured.

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
27.5 ms ... rise ↗ and fall ↘ combined↗ 14.3 ms rise
↘ 13.2 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 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
40.1 ms ... rise ↗ and fall ↘ combined↗ 20.3 ms rise
↘ 19.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.8 ms).



Performance

The IdeaPad Duet comes with a relatively low-performance - for Chromebooks - ARM-based SoC from MediaTek. The Helio P60T offers four big ARM Cortex-A73 cores for performance tasks and four small ARM Cortex-A53 cores for power saving. All eight CPU cores can run at a maximum speed of 2 GHz. Furthermore, the SoC integrates a relatively weak ARM Mali-G72 MP3 graphics card with a speed of up to 800 MHz. The CPU and GPU have to share 4 GB of LPDDR4X memory. A slow 64 GB eMMC flash chip is used as the storage device.

The processor power is rather limited by the relatively weak ARM SoC. In addition, the Android virtual machine costs a lot of performance. Therefore, Android benchmarks like Geekbench, PCMark, and 3DMark show rather modest results, and the cheap 2019 Amazon Fire HD 10 can beat the Chromebook Duet. Moreover, the Android emulation doesn't work perfectly. Not all apps are available for the Duet, and PCMark Work 2.0, for example, crashed the laptop.

The browser benchmarks run "natively" on Chrome OS and show very good performance for the built-in SoC. However, it's not enough to catch up to the budget iPad (6th Generation). Subjectively, though, the browser works well, and you also have a full "desktop browser".

The built-in 64 GB NAND memory shows the expected weak benchmark results in the test. High-end devices like the Galaxy S20 smartphone or, of course, PCIe SSDs in laptops achieve performance values that are 10 times higher in some areas. Compared to other flash-based entry-level devices, however, performance is decent. The Pixelbook, for example, reaches very similar benchmark results.

Games

The weak GPU and the virtualized Android environment aren't very beneficial for games. For example, PUBG Mobile wasn't smoothly playable in the test. Also the less demanding Call of Duty Mobile was only playable with stuttering. However, less demanding games like World of Tanks Blitz (60 FPS at low settings, 24 - 60 FPS at medium settings) run smoothly with low to medium details. But dedicated Android tablets have a clear advantage here.

Emissions

Temperature

Despite the passive cooling, the tablet stays pleasantly cool even during long load periods like when playing Android games. We measured a maximum of 38 °C (~100 °F) on the back as the warmest spot - absolutely uncritical.

Speakers

The small built-in stereo speakers are only sufficient for modest sound reproduction in relatively quiet rooms. With a maximum volume of 74 dB, they don't get very loud. In addition, they offer practically no bass. Therefore, it's very hard to enjoy listening to music. The linear mids are pleasing, but there is a peak at 5,000 Hz for the highs that stands out.

The included headset adapter for the USB-C port offers a suitable performance, but it's very clearly not meant for audiophiles (THD+N of 0.04%). In comparison, the cheap RedmiBook 16 that we recently reviewed offers a better value of 0.025% (smaller is better).

Energy management

Energy consumption

Thanks to the energy-efficient MediaTek SoC, power consumption remains pleasantly low. At a consumption of over 3 watts, the display's brightness has the biggest impact without load. But at a maximum of 9 watts, you don't have to fear a high electricity bill even under full load and at maximum brightness.

Battery life

The low power consumption helps the IdeaPad Duet Chromebook achieve very good battery life. At a reduced brightness of 150 nits, we measured a very good runtime of 12.5 hours. Consequently, a complete workday is no problem for the small tablet.

Pros

+ good battery life
+ low emissions and silent cooling
+ 8 years of Chrome OS updates

Cons

- UI suffers from stuttering
- slow SoC
- very thick with keyboard and Stand Cover
- external monitor only runs at 1280x720

Verdict

The Lenovo IdeaPad Duet is a small convertible that runs on Chrome OS. Thanks to the support of Android and Linux, there are numerous application possibilities for the small tablet. But you keep in mind that Android and Linux are only running virtually on the device; consequently, you have to live with reduced speeds.

Even the native Chrome browser makes the MediaTek SoC sweat, and you have to live with slight stuttering.

But in return, you get a full desktop browser, and in combination with Linux, an exciting mobile solution for web developers. But if you only want to use Android apps and don't need a desktop browser, an Android tablet or an iPad is probably a better choice for you.

The technical measurements of the IdeaPad don't stand in its way. The display shows good characteristics - especially for the price range. Users will most likely wish for even higher brightness for outdoor use in the sunlight. The keyboard and touchpad are suitable for the size and price range - but frequent typers should rather resort to larger devices here. Moreover, there's nothing to complain about in terms of battery life and emissions. As a result, the combination of Linux, Android, a full-fledged Chrome browser, long battery life, and mobility could be an exciting compromise for some users.
