When the first electronic paper book was launched in 2019, we knew that there would be a higher Pro version. So many interested fans did not choose to buy the one with a smaller screen. But who ever thought, they would have to wait more than a year. The 2020 epidemic has repeatedly delayed the release plan. At the end of 2020, Xiaomi Mi Watching Electronic Paper Book Pro finally made its debut.
Compared with the first generation, the Xiaomi Mi Watching Electronic Paper Book Pro has made sincere upgrades from the outside to the inside to support its Pro positioning.
In terms of external design, the most intuitive change of the Xiaomi Mi Watching Electronic Paper Book Pro is the screen and thickness. The screen has been upgraded from 6 inches to 7.8 inches, which is larger and more delicate at the same time. The resolution reaches 300ppi, which is enough to ensure that more text is displayed without losing the details of the text strokes. It not only retains the 24-level backlight adjustment, but also adds the adjustment settings of cold and warm light to meet various reading light habits. In addition, the body is 1.3mm thinner than the previous generation, and it is more comfortable to hold with one hand.
In terms of core configuration, the Xiaomi Mi Watching Electronic Paper Book Pro still uses the Allwinner B300 SOC chip specially designed for e-book products. But a new hardware EPDC controller is added to make the page turning operation smoother and lower power consumption. Both memory and storage have been doubled. The combination of 2GB+32GB can ensure the smooth operation of the entire system of e-books, and can also store more e-books locally.
In terms of software, the Xiaomi Mi Watching Electronic Paper Book Pro still has the built-in custom system. You can also instal third-party apps.
Unlike the first generation, the packaging of Xiaomi Mi Watching Electronic Paper Book Pro has turned dark blue. The front rendering of the product is printed with the famous sentence “Anything in the past is a prologue” from Shakespeare’s “The Tempest”.
Take out the main body, the overall design has no different from the first generation except that it turns black. This time the screen size has been upgraded from 6 inches to 7.8 inches. So the frame also looks smaller accordingly.
As the screen becomes larger, the resolution improves even more. The pixel density of the screen has also been increased to 300ppi. And the effect of displaying text is more delicate, without worrying about burrs, let alone being unclear in small fonts.
There is only one touch button at the bottom of the front.
The side thickness of Xiaomi Mi Watching Electronic Paper Book Pro is only 7mm, there are not many physical buttons, and a set of volume buttons on the right.
The power button on the top is used to switch the machine, turn off the screen and turn on the screen.
The bottom data/charging interface is Type-C. It supports up to 10W input.
First of all, let’s talk about the improvement in display effect of Xiaomi Mi Watching Electronic Paper Book Pro. Needless to talk about the advantages of larger screens. Higher pixel density and more advanced backlight system can bring a more comfortable reading experience.
With a large screen and a pixel density of up to 300ppi, even when reading pdf files, it can ensure the clear display of small fonts without causing too much difficulty in reading.
The lighting not only increases the number of adjustment levels, but also provides cooling and heating adjustment options to meet users’ preferences for various reading lighting conditions.
In addition, in terms of page-turning effects, the Xiaomi Mi Watching Electronic Paper Book Pro also provides two options for normal and fast modes. The fast page turning mode has a faster refresh speed, which can greatly reduce the inertia when turning pages. But the fast page turning mode also has a certain price. It will be more than the normal mode when switching between a large area of black pages and white pages.
The Xiaomi Mi Watching Electronic Paper Book Pro also supports the installation of third-party applications. In the About column of the system settings, click the WLAN MAC information multiple times to enter the application management window. Use the file manager to install third-party applications and open third-party applications without any problems. However, third-party applications are not adequately adapted to the electronic paper book ink screen. So be prepared for abnormal grayscale display, power consumption, and freezes on the page.
Many people think that the performance of the Allwinner B300 is weak, and the 28nm process will have a certain impact on the overall battery life. But in fact, the performance of Allwinner B300 is sufficient for reading e-books and simple system settings. Moreover, with the aid of the hardware EPDC controller, while the fluency of page turning is improved, the processor itself will only work at very low power consumption when reading text.
Therefore, unless it is to turn on the high power consumption functions such as Wi-Fi networking, the battery life performance of Xiaomi Mi Watching Electronic Paper Book Pro will still not let us down.
Battery life test in the networked state
When the network connection is turned on and the brightness is maximum, one page is read in 25 seconds. After 50 minutes, the power consumption is 8%. The final battery life is expected to be about 10.4 hours.
Battery life test in the off-networked state
Turn off the network, we test again. Under the same conditions, the power consumption within 2 hours is 10%, and it is expected to easily reach 20 hours of battery life.
If you want a longer battery life, you can turn off the backlight to reduce the reading speed. Daily reading of books will not last for 20 hours.
The Xiaomi Mi Watching Electronic Paper Book Pro sports a 7.8-inch electronic ink screen with 300ppi. With this screen alone, Xiaomi can compete any rival in the same price range of 1,299 yuan. All products at the same price are 6-inch products. For reading, the difference in size determines the content that can be displayed on a page. This will naturally have a fundamental impact on the reading experience.
