Nvidia Tegra K1 processor with 4-core 2.2GHz A15 architecture and 7.9-inch 2048 x 1536 resolution screen (326 ppi) make Xiaomi tablet the strongest Android tablet available in China.
But when it first started shipping, it only used MIUI V5 system, and it also officially upgraded MIUI 6 not long ago. After the new system is installed, will its performance and performance be significantly improved? Now let's have a look.
System bottom layer
After upgrading the system, the desktop changes little. It is also a classic single menu of MIUI. On the left side of the desktop is the widget center, where all desktop widgets/plug-ins can only be placed.
However, several magic plug-ins provided by the government can just be put together into one set, and players and computers can be operated directly on the desktop, which is more convenient to use.
The time of the top notification bar has been moved to the left, and the name of the connected WiFi and the real-time network speed can be displayed on the right.
The notice bar has a real-time frosted glass effect. The left side is a notice, and the right side is a shortcut switch. It supports the user-defined sorting function, but can only change the sorting instead of hiding the switch.
The menu key becomes a task management button. In the manager, double finger zoom can be switched between thumbnail and icon modes. It supports pull-down locking and upscaling clearing tasks.
The system is based on Android 4.4.4, and the kernel version is still 3.10.24. The setup page is a flat double column design. The biggest advantage of the column interface and high resolution is that you can see all the items at a glance without having to scratch the screen.
However, privacy related pages such as privacy protection and owner information, as well as system application settings, will be displayed in full screen instead of columns. Plus the machine resolution is extremely high, these pages will appear empty.
The list on the left is almost the same as the mobile version of MIUI6. MIUI6 rearranges the setting items and places many advanced settings such as display, power, developer options, etc. in the second level menu. Ordinary users may feel much refreshed, but geek or advanced users may feel a little inconvenient.
The settings of 11 system applications, such as "cloud service, contacts, calendar, and search", are unified to the settings page. The rice coin, game and app store are all separated into one piece.
The system settings have been simplified to a certain extent. There is no common color temperature adjustment in MIUI, but the breath light color and key customization are reserved. The key control can also change whether the function of the task key is the task manager or the setting menu. The keyboard light is also available.
Since the security center was canceled, the self startup management was placed on the settings page. and Customizations of browser, camera and music have been greatly reduced, and changes in email conversation mode are the same as those of mobile MIUI6.
New single hand model And it is also a new way to enter: move any two of the three Vajra keys at the bottom of the left and right strokes, and stroke in different directions to generate a left and right hand single hand mode (it cannot be shown on the screenshot, but can only be taken in real time). However, it seems that few people will use one hand mode on the tablet.
The native keyboard is also different. The Chinese input mode has left and right columns, word selection on the left side, and Chinese 9 grids on the right side. It is comfortable to use.
System application
weather
music
calendar
Calculator
Weather, photo album, music and calendar applications are basically the amplification of the mobile version, because the screen is larger and the display content is very loose.
note
contacts
File Manager
Note, contact and file manager applications have left and right columns, which are more efficient than the mobile version.
The browser has been greatly simplified. It is in tab mode by default and supports double clicking to close the label.
The camera application also has an exposure compensation ring on the mobile phone. I like it silently.
Although the built-in information application is HD version, it is very similar to the mobile version.
The application market and Xiaomi Mall have been really HDized.
performance
The memory occupation of the new system is similar to that of MIUI V5. The available memory is 1G after startup, and it will remain between 600-700m after several applications are opened.
When the GPU is turned on, the curves are basically below the green warning line. Although the fluency is not as exaggerated as the native Android 5.0, the fluency in system applications is completely OK. However, the curve can only run in half screen, maybe it is not adjusted well?
When the performance mode is turned on, the system basically runs at a single core speed of 1.2GHz (up to 2.2GHz), leaving a lot of room.
In the face of the performance cancer of the third party, such as post bar and microblog, the frenzy performance brought by Tegra K1 is basically two cores running, still close to the full frame, and the curve rarely crosses the green line.
The score performance is similar to that of MIUI V5, and slight numerical difference can be basically considered as test error.
The picture of the top flight car 17 is exquisite, almost full frame (average frame rate is 58), but the special effects on the body seem incomplete.
On the wild drag racing 8 which has always performed poorly on the Android platform with Special effects Complete with an average of 32 frames.
The real car is also full of special effects, but the picture definition is not high, and the average number of frames is 43.
Modern Warfare 4
Call of Duty
Death trigger 2
The test results of the game can be summed up as follows: the average frame rate of real racing, modern war, call of mission, death trigger and other games is between 42-48 frames, except for the wild drag racing 8, which is unable to support, and the average frame rate of the game is between 42 and 48 frames. The best speed car is almost full frame, and it can often make two of the cores sleep, so there is much left to do. With Tegra Kepler framework GPU of K1 needs to feed 2K screen (2048 X 1536) is relatively well-off.

The most worrying thing about Android tablet is the adaptation of third-party applications. Now the mainstream applications are basically adapted to the HD version, and the image DPI adaptation has finally caught up with the trend of 2K screen, and there is no problem of image deformation due to the 2:3 screen of Xiaomi tablet.
Of course, there are exceptions. Youku is quite stubborn.
It's also very happy to see a cartoon on a high screen. You can see the details without zooming in.
MIUI 6 can be rooted with one click. After that, GMD gesture control (without gesture control, there is no sense of happiness) and exposed frameworks can be safely installed, but the app setting used to change the application DPI does not work
In terms of power consumption, there is little difference from MIUI V5. When playing a large game, Tegra K1 is not a fuel efficient light. The power consumption rate per hour is about 20-30%, which is equivalent to 4-5 hours of endurance. For ordinary system application operation, the power consumption per hour is between 6-9%. Reading a book can even last for 8 or 9 hours. The performance is good.
summary
Although MIUI 6 has just adapted to the Xiaomi tablet, its system optimization and performance are similar to those of MIUI V5. With Tegra K1's violent performance, no matter whether it has been upgraded or not, the machine can play almost all the games that can be seen in the market. Moreover, the conscience configuration of the native support TF card makes the Xiaomi tablet a quite competent game machine.
For Xiaomi tablet, in addition to more delicate animation and flatter interface, MIUI 6 upgrade is more a small improvement at the system level. Although the range is not large, the player recommended that old users upgrade. After all, after the new system comes out, the bug repair and function increase speed of the old system will slow down.
In addition, the price of the millet tablet after the price reduction has also reached a very conscientious price. Considering the inventory and subsequent production restrictions, it is recommended that users who need high-definition screens and game performance should start when there is still stock.
