Personalizing the look of wearable electronics has become more than just a bonus, it’s a full-fledged part of the user experience. For owners of Xiaomi Mi Band 4 fitness bracelet, the ability to change the dial opens up hundreds of unique designs that display weather, steps or just beautiful graphics. The standard set coming from the factory often feels limited and boring, especially when thousands of creative options are available online.
The process of replacing the interface requires understanding the architecture of the device, since there is no direct file change through the file manager of the bracelet. Synchronization occurs exclusively through the mobile application, which acts as an intermediary between the Internet storage and the internal memory of the tracker. It is important to realize that the display quality and response rate depend on the firmware version and model of your smartphone.
In this article, we will take a look at all the legal and proven ways to install new dials, learn how to use official repositories, third-party downloaders, and even how to create your own design from scratch. The right interface configuration will not only improve the visual experience, but also increase the functionality of the device, bringing to the screen the data that is important to you.
Official method through the Mi Fit app
The safest and most stable way to change the appearance is to use the regular software. Mi Fit (or Zepp Life, depending on the region and version of the update) contains a built-in dial store, where you collect proven designs. To start, you need to make sure that your bracelet is paired with your smartphone and is in the zone of confident reception of the Bluetooth signal.
After you start the app, go to your device profile, usually by clicking on the bracelet icon at the bottom of the screen. Next, look for Profile → Mi Band 4 → Dial settings (or a similar menu item depending on the translation version).
When choosing a new design, pay attention to its size and functionality. Some dials contain animations or complex widgets, which can slightly increase energy consumption. Once you press the "Install" button, the process of downloading data to the bracelet begins. At this time, keep the smartphone near the device and do not lock the phone screen so as not to interrupt the transmission of data packets.
⚠️ Warning: If the bracelet screen is out during installation or synchronization error occurs, do not immediately try to reset the device. 2-3 minutes), then repeat the procedure, before restarting the smartphone.
The official store is regularly updated, adding seasonal themes and collaborations with well-known brands. However, the directory can be limited depending on the account and the region of registration. If you do not find the desired design in the list, this does not mean that it can not be installed - there are alternative methods for expanding the library.
Use of third-party bootloader applications
The development community around the Xiaomi ecosystem has created powerful customization tools that often outperform the functionality of official software, the most popular being the Notify for Mi Band app available on Google Play, which allows you to download dials from a vast database managed by users from around the world.
Installing a third-party bootloader requires advanced access rights. The application will request permission to use Bluetooth, access to notifications and the file system, which is necessary so that the program can independently “slip” dial files into the clipboard of the official Mi Fit application, simulating the user’s actions.
- 📱 Download and install Notify for Mi Band from the official Google Play Store.
- 🔗 Run the program and pair with your Mi Band 4 by following the instructions on the screen.
- 🎨 Go to the "Digitals" section and select the "Online" category to access the database.
- ⬇️ Click on your favorite design and select "Download and install", the application will automatically perform all the necessary actions.
Using third-party software gives access to the second-hand dials, which is not officially supported in the basic firmware Mi Band 4. Also available are designs with increased detail and non-standard fonts. However, it is worth considering that such dials can be heavier for the bracelet processor.
Security of Third Party Applications
Creating your own dial from scratch
Creative users can create a unique design that no one else will have, a process that requires a special editor on a PC, such as Amazfit Watchfaces or online designers, so you can upload any photo, customize fonts to display time and steps, and arrange the interface elements arbitrarily.
The process begins with the selection of a base image. It is recommended to use graphics with a resolution of 120x240 pixels, since this is the physical size of the Mi Band 4 screen. Using images of higher resolution will lead to automatic compression and loss of quality, and less to stretch and appear artifacts.
After setting up all the elements (hours, minutes, date, steps, calories), the project must be exported in.bin format. This file is a ready-made dial. Then it can be transferred to the phone and opened through the bootloader application or Mi Fit, if the file format was generated correctly.
💡
When creating your dial, use contrasting colors for time digits. The AMOLED screen is great at black, but in sunny weather, readability can drop if the text merges with the background.
Table of compatibility and characteristics of dials
Not all dials have the same effect on the device. Complex graphics and the presence of the second hand require more computing resources and power. Below is a comparison table that helps you choose the best option depending on your priorities: autonomy or visual component.
| Type of dial | Impact on the battery | Availability of animation | Complexity of installation |
|---|---|---|---|
| Static (official) | Minimum | No. | Low. |
| With the second hand | Average. | Yes (seconds) | Medium |
| Animated (GIF) | High. | Yes (constantly) | Tall. |
| Photo dial | Low. | No. | Medium |
As you can see from the table, the most energy-intensive options are those with permanent animation. If you plan to use the bracelet in maximum autonomy mode (up to 20 days), it is better to abandon live wallpaper. For everyday use, the optimal balance is static dials with large, easy to read fonts.
It’s also worth noting that some complex dials can cause micro-slowdowns when switching screens.This is normal for the Mi Band 4 architecture, as the device’s processor is not designed to handle heavy graphics in real time.
Typical problems and methods of their solution
When experimenting with themes, users often encounter technical difficulties, the most common being a synchronization error, where the progress bar freezes by 99% or the process is interrupted in the middle, which can be caused by an unstable Bluetooth connection or background Android processes that kill the app to save energy.
To solve the problem, it is recommended to add the Mi Fit app and dial loader to the list of energy saving system exceptions. On Xiaomi smartphones, this is done through the Security menu → Battery → Autostart. It is also useful to clear the cache of the Mi Fit app before trying to re-install the theme.
⚠️ Warning: Never interrupt the firmware process of the dial by turning off the smartphone screen or leaving the Bluetooth range.This can lead to a software failure in which the bracelet will stop displaying the image (white screen.
☑️ Diagnostics of installation problems
Another problem may be the incorrect display of fonts, especially Cyrillic. If instead of letters you see squares or characters, then this dial does not support Russian, in such cases, it is worth looking for a Russified version or using fonts from the official Xiaomi library.
The impact of topics on autonomy of work
The issue of power consumption remains a key issue for wearable electronics: the AMOLED screen used in the Mi Band 4 consumes energy in proportion to the brightness and number of pixels burning. The black background saves charge, while bright, white or colored themes make the pixels work more actively.
Using an “always on display” in combination with a bright dial can reduce the device’s life from 14 to 5-7 days. If you care about autonomy, choose themes with a predominance of dark tones and minimal active elements.
Animated elements, such as running strings or pulsed indicators, also contribute to the discharge. The processor is forced to update the image more often, which leads to additional energy consumption. For maximum battery life, choose simple, static images.
💡
The best choice for saving battery is a static dial with a dark background and large numbers, without a second hand and complex widgets.
