Lenovo Smart Paper review – An e-ink tablet housed in a stable metal case

Bookworm. The Smart Paper is a high-quality e-ink tablet made by Lenovo which you can use for easy note taking and to help you study documents without getting tired. Although the device is based on Android, you can hardly run any apps on it. In this review, we will find out about what the tablet can and can't do.
Lenovo Smart Paper

E-ink screens are all the rage at the moment - after all, they strain your eyes much less than a conventional phone or tablet display while reading. They can also be used really well outdoors and are great for taking notes.

The Lenovo Smart Paper utilizes this type of display and in addition, its pen input, free accessories and a great case are all quite impressive. At the end of the day, how much you can really get done on this tablet does depend on the software and whether you can install any apps onto it.

So, let's take a look at how the Lenovo Smart Paper did in our tests and in everyday use.

Case – Attractive aluminum

If you've already held a current tablet from Lenovo, then you'll feel a sense of familiarity with the smart paper: Its great aluminum case with a two-toned back (achieved through different textures) as well as the brand name on the side can be found on other Lenovo tablets, too. Beveled edges which let the silver material shine and the case that can hardly be bent both contribute to how high-quality this device feels.

Compared to the Huawei MatePad Paper, our test device is a little bigger, but in turn, it's also slimmer. The Smart Paper is also around 50 grams heavier than Huawei's e-ink tablet which has a simple plastic case - during periods of longer use, this can make all the difference.

There are quite thick bezels surrounding the screen, but this makes sense on a tablet, as you don't want to constantly be accidentally activating the touchscreen. One side of the frame is actually even wider - this side lets you store away the stylus and it also lets you hold the tablet with one hand, as if you were holding a book.

Features – Rather sparse

You can already tell that the Lenovo Smart Paper is no regular tablet when you look at its meagre features: No microSD card reader, no headphone jack, no camera, no speakers and no locating system.

With 4 GB RAM and a 64 GB eMMC flash, its memory isn't the largest for US$400. Although, you can barely load any images and video onto the tablet's black and white and slow-reacting e-ink display anyway, so you likely won't need much storage space.

Its USB-C port can be used to charge the tablet and to transfer data to and from your PC. You can also do this wirelessly using Lenovo's Companion app.

Software – Based on Android 11

Lenovo has installed an operating system which is based on Android 11 AOSP, meaning the open-source part of Android. Its surface is kept clean and simple in line with the screen's limited capabilities.

Android apps can't officially be installed but you can still do this via apk files - although, we had some start-up difficulties in our test. This means you are able to install your preferred e-book store apps - ex works, the tablet only has ebooks.com preinstalled, which also only has the option to download books in English. 

Furthermore, Lenovo has preinstalled a calendar, calculator, notes app and an e-mail app onto the tablet. The Paper Smart can also depict e-books which have the native Epub format - and, of course, txt and pdf files as well.

You can't expect to see a completely new version of Android at any point, but according to Lenovo, the tablet is supposed to receive security patch updates for at least 2 years from its release date (mid 2023).

Communication and GNSS – WiFi 5 with good reception

Lenovo's Smart Paper features WiFi 5, the fastest standard. Although, the MLAN module can't really take advantage of the speedy standard - its transmission rates were only 211 - 286 MBit/s, which is considerably below our expectations.

In practical use, it actually takes quite a while for websites to load - even if you are quite close to the router. Images take even longer. With a distance of 10 metres to the router with 3 walls in between, you only have access to 3/4 of the reception - websites barely take any longer before they appear on the tablet's screen.

Accessories and warranty – Lots included

Aside from the device itself, Lenovo also includes a charger, USB cable, input pen as well as a matching folio which features a space to store the pen.

The manufacturer has given the product a 12-month warranty within the United States.

Input devices & operation – Precise input pen

The touchscreen recognizes our inputs precisely most of the time, but its reaction is a little delayed. The reason for this is the display's low frame rate and the slow image build-up compared to LED or OLED screens. The tablet's limited performance is also a bit of a problem - websites loading slowly occasionally delays the input in search fields or letters are swallowed because the input could not be processed.

On the other hand, the tablet can certainly shine when the passive stylus is used. It doesn't have to be connected via Bluetooth, has 4,096 pressure levels and it only weighs 15 grams. Although there is a minimal delay when drawing or writing, it is negligible. Lenovo speaks of a latency of 25 milliseconds. Its numerous pressure levels can't be used quite as finely on Lenovo's Smart Paper, but the result is still decent.

The tablet's matte and slightly roughened surface almost feels like paper and it is very pleasant to write on.

In terms of security, there is no fingerprint sensor or face scanner: Only a PIN can be set to protect the tablet from unauthorized access.

Display – Great contrast, but not suitable for videos

Subpixel array

Lenovo's Smart Paper features a 10.3-inch display which has a resolution of 1,872 x 1,404 pixels - the exact the same specifications as Huawei's MatePad Paper.

An e-ink display is something very special due to its technology: Here, black and white ink particles with different electric charges are mixed within each pixel so that 16 different shades of gray, full black or white can be displayed. Since these are real color particles in front of a monochrome background, you don't necessarily need good lighting to read the display. Thanks to its high contrast and matte surface, even ambient light is enough to do so.

However, it also features an LED backlight which is supposed to enable reading at night and as a result, doesn't have to be as powerful as in other tablets: The screen brightness can reach up to 116 cd/m².

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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured.

In our measurements using a spectrophotometer and the software CalMAN, the deviations were partly quite high because the limited number of grayscale levels is not enough to correctly represent every brightness nuance. Its white reproduction was nevertheless quite good with the backlight providing a cool white balance.

PWM does not exist in e-ink displays, and once the image is built up, it is only refreshed after a relatively long time anyway. This means you can only enjoy videos or games to a very limited extent, and there are also delays during inputs.

Ghost images also remain from time to time, which have to be removed by manually refreshing the screen.

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↗ 14.4 ms rise
↘ 13.1 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 0.1 (minimum) to 240 (maximum) ms. » 66 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.5 ms).
       Response Time 50% Grey to 80% Grey
134.4 ms ... rise ↗ and fall ↘ combined↗ 56.2 ms rise
↘ 68.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 100 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.7 ms).

Outdoors, the display manages fine without any backlighting and can be read from well even on bright days thanks to its matte coating. Only when the sun falls directly on the display are there reflections that cover the screen content.

The viewing angles are perfect, you can read from the screen from all directions in exactly the same quality.

Performance – We expected to see more

The Rockchip RK3566 is a rather unusual SoC for us to see because it is actually too weak to be used in even very cheap tablets or smartphones. With only 4 Cortex A55 cores, its power is sufficient for simple tasks like taking notes or reading documents, but as soon as it gets a bit more demanding, there are heavy delays - if the apps are even able to be booted up at all.

You can see in the benchmarks that other tablets and also Huawei's MatePad Paper offer much more power: Our test device was always far behind and in last place.

While surfing the internet is possible with Lenovo's Smart Paper, it isn't really much fun: On the one hand, pages load quite slowly and on the other hand, complex animations or advertising banners often hinder smooth operation. For example, you often have to wait a long time before you can use search fields without any problems.

The Lenovo Smart Paper doesn't do itself any favors with its eMMC flash either: It is very slow and the storage controller slows things down even further. Huawei MatePad Paper features UFS 2.2 flash and, as a result, much faster data transfers and load times.

Games – Just the basics

Gaming is hardly possible on the e-ink tablet, apart from very simple games like Solitaire. The SoC's weak components also slow down the gaming experience.

The tablet does not allow us to enable USB debugging, so we unfortunately cannot perform any game benchmarks.

Emissions – Hardly heats up, no throttling

Temperature

The case heats up to a maximum of 34.1 °C, which you can feel a little bit but this is in no way uncomfortable. This means you will never experience the tablet overheating and the SoC has no issues with heat dissipation. During the stress test with 3DMark and Wild Life Extreme, the system achieved low but consistent values - even after 20 runs of the benchmark.

Speakers

Lenovo hasn't installed any speakers into the Smart Paper, leaving audiobook fans out in the cold. Audio output to headphones or speakers via the USB-C port and an adapter is also not possible.

You can only listen to sound via Bluetooth. The sound signal proved to be clean and good in our test. Unfortunately, the Smart Paper doesn't give us an insight into which codecs can be used, but we got an LDAC signal via Sony's Bluetooth headphones, so at least this standard is certainly available.

Annoying: Since Lenovo's Smart Paper does not have a physical volume control, you always have to adjust the volume on the tablet directly or via the headphones/external speaker.

Power management – Stamina in everyday use

Power consumption

In our consumption tests, the Lenovo Smart Paper proved to be quite demanding in parts despite its low performance and uses quite a lot of energy. Up to 7.1 watts are consumed under full load.

One of the biggest battery guzzlers is clearly the display's backlighting. However, if it is turned off and the display doesn't update, no energy is consumed because white and black ink particles in the screen can maintain their state without a power supply.

The tablet can be charged with up to 10 watts. When the battery is completely empty, you have to wait up to 3 hours before the charging indicator shows 100% again.

Runtimes

Some of our battery tests unfortunately can't be run with the Smart Paper since they require a screen brightness of 150 cd/m², which the display is unable to reach. However, the tablet lasts 4:38 hours under high load, which is half an hour more than the MatePad Paper.

The idle test corresponds to regular page-turning with the backlight off and WLAN disabled. You can browse through documents for 17:36 hours here. The tablet lasts for about 9 hours with full illumination when pages are turned regularly.

Lenovo Smart Paper review.
Lenovo Smart Paper review.

The Lenovo Smart Paper is an interesting device which impresses upon first glance with its high-quality design: The attractive aluminum case is very stable and its beveled edges look great. Plus, you receive a protective case and a passive input stylus with the device - the latter letting you take notes as if you were writing on paper. If needed, these can automatically be transformed into block letters straight away.

However, there are quite a few points which make the Lenovo Smart Paper a little difficult to market over its competitors: On the one hand, the 10.3-inch tablet is quite heavy, weighing over 400 grams. If you are holding the device for longer periods of time, then you begin to notice the difference compared to lighter tablets such as the Huawei MatePad Paper.

Its processor performance is also comparatively low and installing apps is a bit of a nuisance. Its bare features which don't include speakers, a volume rocker, microSD card slot or a fingerprint sensor are also a disappointment. In order to enjoy an audio book, you'll need a pair of Bluetooth headphones.

On the other hand, the Lenovo Smart Paper is great at doing its intended job: Taking notes, reading books and documents, quickly searching for something on the web, or to write one or two emails. 

The Lenovo Smart Paper is a good digital notebook, a reliable document reader and, to a certain extent, a good companion for surfing the web. Unfortunately, the e-ink tablet is simply too weak and inflexible for any more demanding tasks.

Of course, you can't really run any graphically demanding apps on an e-ink display, but especially devices such as the MatePad Paper offer more power, speakers and a fingerprint scanner - which provides users with considerably more flexibility.

If you aren't likely to use the note-taking function or the speciality features of the e-ink display (such as good readability in bright light and good contrast levels), then it would make much more sense to go for a conventional tablet anyway.

Price and availability

The Lenovo Smart Paper has an MRSP of US$399 but it currently isn't available to buy in the US. You can find it on Lenovo's UK website for £400 (around US$510).
