Modern wearable gadgets have long ceased to be just utilitarian devices for counting steps, turning into a stylish accessory that complements the image of the owner. That is why the question of how to change the wallpaper on the Xiaomi Mi Band 3, worries thousands of users who want to stand out from the crowd of standard dials. OLED-display that allows you to display not only time, but also full graphic images.
The process of customizing the bracelet interface has been made much easier with the release of updates for the official Mi Fit app (now Zepp Life) and the introduction of third-party utilities. However, despite the seeming simplicity, there are many nuances associated with file formats, screen resolution and image compression algorithms. If you just upload a photo from a smartphone camera without preprocessing, the result on a small screen can disappoint you.
In this article, we will take a detailed look at all the available ways to install personalized dials, review the necessary tools and answer frequently asked questions, learn how to properly prepare graphics to make them look bright and clear, and learn how to avoid common mistakes when synchronizing data between your phone and tracker.
Technical features of the display and graphics preparation
Before you start uploading images directly, you need to clearly understand the technical limitations of the device. The screen Xiaomi Mi Band 3 has a resolution of 128 by 80 pixels, which is quite low by modern standards. This means that complex gradients, small details and text can “wash” or become unreadable when you transfer the bracelet to the screen.
The key is to choose the right image, and the resolution of the image must be strictly consistent with the matrix or multiple to avoid zoom artifacts. 128x80 pixel 256x160 pixels for later reduction. Color rendering OLED-The matrix is also different from LCD-Smartphone screens: black is deep and not highlighted, and bright colors can look more saturated.
Why does the picture look worse on the bracelet?
To prepare the perfect image, it is recommended to use graphics editors such as Photoshop or free analogues such as GIMP. In the processing process, it is important to consider that part of the screen will be occupied by battery, pedometer and time indicators if you create a dial from scratch.
Official method through the Mi Fit app
The safest and most stable way to change the look of a tracker is to use the manufacturer’s software, the official Mi Fit app (now renamed Zepp Life) has a built-in dial store, as well as a custom photo installation feature, which does not require superuser rights or dubious software installation.
To start the process, make sure your bracelet is paired with your smartphone and has a battery level of at least 20%. Low charge can interrupt data transfer, which will lead to an installation error. Open the application, go to the device profile and find the section responsible for the design of the screen. Here you will see the Add button or the plus icon.
☑️ Installation algorithm via Mi Fit
Once you select a photo from the phone gallery, the system will suggest framing the image, which is a critical step, because this is where you determine which part of the photo will hit the screen, move the frame so that the main object is in the center of the composition, and once the selection is confirmed, the conversion and loading process will begin, which can take from 30 seconds to several minutes depending on the speed of the Bluetooth connection.
Use of third-party applications for enhanced capabilities
If you don't have enough of the official app, you can use dedicated utilities developed by enthusiasts, and one of the most popular tools is the Notify for Mi Band app. It provides access to hidden tracker functions, allowing you to install not only static images, but also GIF-animation, as well as create complex dials with the output of any information.
Working with these applications requires care. Once installed and paired through the main Mi Fit interface, you need to open the third-party utility and give it all the permissions you want. In the settings menu, find the section responsible for the dials (Watchfaces), here you can download a pre-prepared.bin file or create a new one using the built-in editor.
⚠️ Note: Third-party apps may request access to notifications and geolocation. Use only proven utilities from official Google Play or App Stores to avoid personal data leakage.
The advantage of using advanced tools is that you can fine-tune the brightness, contrast and arrangement of the elements. You can create a dial that will vary depending on the time of day or the level of light, but it is worth remembering that complex graphics can slightly increase the energy consumption of the device.
Step-by-step instructions for creating and loading the dial
For those who want to create a unique design from scratch, there is a clear algorithm of actions: first, you need to prepare the image in a graphics editor, observing the proportions of 128x80 pixels. Then the file is saved in JPG or PNG format. Next, using a converter (often built into the editor applications of dials), the image is packaged in a special container that is understandable by the firmware of the bracelet.
Once you have a.bin or.watchface file, you have to send it to the device, either through the application file manager or by direct transmission to the dial folder, and when you transmit it, the screen of the bracelet can go out and light up, which is the normal response of the system to update the display buffer.
It's important to keep the sync process running. If you see a progress bar in the app, wait until it's full. In some cases, you may need to reboot the bracelet to apply the changes. To do this, find "Reboot" in the device menu or press the touch button for a few seconds.
Comparison of wallpaper installation methods
The choice of installation method depends on your goals and technical background. For most users, the best option is a standard application that provides stability. However, enthusiasts will appreciate the flexibility of third-party solutions. Below is a table comparing the main characteristics of different approaches.
| Characteristics | Official appendix (Mi Fit) | Third-party utilities (Notify) | Manual creation (Bin files) |
|---|---|---|---|
| Difficulty | Low. | Medium | Tall. |
| Graphics quality | Automatic compression | Customizable | Maximum. |
| Animation support | No. | Yes (GIF) | Yes. |
| Risk of error | Minimum | Medium. | High-pitched |
As the comparison shows, manual dial creation gives the most control over the outcome, but requires learning the structure of firmware files. Official methods are limited to developer functionality but guarantee compatibility. The balance between quality and simplicity is often found in the use of advanced third-party applications.

For daily use, static dials with a dark background are best suited, since they consume less battery power. OLED-screen.
Typical problems and ways to solve them
Users often face a number of challenges in personalization, and the most common problem is that the image doesn't install or looks distorted, which can be caused by an unsupported file format or too large a source size, in which case you can try to reduce the file size to 500 KB and resave it to JPG with a quality of 80%.
Another common complaint is time desynchronization or sensor failure after installing a heavy dial. If the bracelet starts to work unstable, perform a full reset via the app. Also make sure that the firmware version of your Mi Band 3 is up to date, as older versions of the software may not work properly with new dial formats.
⚠️ Warning: If after installing the new dial, the bracelet has stopped responding to touch, don't panic. 10-15 minutes – this often forcibly restarts the system and restores performance.
Color rendering problems, when the colors on the screen are faded or inverted, are solved in the settings of the dial editor app itself. Check if it is worth checking the "Invert Colors" or "Energy Savings" check box, which can change the palette.
