How to download music on Xiaomi Watch S1: 4 proven ways + storage tips

The Xiaomi Watch S1 is not only a stylish accessory, but also a full-fledged music player that allows you to listen to tracks without a smartphone. However, many users face difficulties when trying to download music for the first time: the Mi Fitness app does not offer obvious options, and the internal memory is limited. In this article, we will discuss all the current ways to download music on the Watch S1 – from official methods to workarounds for experienced users.

It is important to understand that the Xiaomi Watch S1 supports only certain audio file formats (.mp3,.aac,.wav), and the amount of available memory depends on the version of the watch (the standard model has 2 GB of internal memory, of which about 1.2 GB is available to the user).

If you’ve tried to download music and you’ve got a bug like “Not enough memory” or “No format is supported,” don’t despair. There’s a problem-solving section in the article, and a unique way to download through ADB that works even on restricted firmware.

1.Official method: download via the Mi Fitness app

The easiest and most recommended method is to use the proprietary Mi Fitness app (formerly Mi Fit), which requires no additional software and is suitable for most users, but it has limitations: for example, you can not download playlists directly from Spotify or Apple Music, only local files from your smartphone.

Here's the step-by-step instruction:

1. Make sure that the Xiaomi Watch S1 is connected to your smartphone via Bluetooth and synced with the Mi Fitness app.
2. Download music files to your phone (for example, to the Music or Downloads folder). Supports.mp3 and.aac formats.
3. Open Mi Fitness, go to Device → Xiaomi Watch S1 → Music.
4. Click Add Music and select tracks from your phone’s memory. Note: the app may not display files if they are stored in cloud services (e.g. Google Drive).
5. Wait until sync is complete. The speed depends on file size and Bluetooth connection stability.

⚠️ Note: When downloading through Mi Fitness, the watch must be charged at least 50%, otherwise the process may be interrupted. Also note that the application automatically converts files to 128 kbps if the original bitrate is higher - this reduces the sound quality.

2. Alternative method: download through file manager (for Android)

If the official method doesn't work, or if you want to upload files bypassing Mi Fitness, you can use the file manager on an Android smartphone, which requires a little more action, but gives you more control over the processes.

This will require:

• 📱 Smartphone on Android 8.0+ root rights (optional, but simplifies the process).
• 📂 File Manager with access to system folders (e.g. Solid Explorer or FX File Explorer).
• 🎵 Music files in format.mp3.aac (maximum bitrate: 320 kbps).

Instructions:

1. Connect the watch to your phone via Bluetooth and activate File Transfer mode in the Xiaomi Watch S1 settings (path: Settings → Connections → Data Transfer).
2. Open the file manager on your smartphone and go to the music folder.
3. Select the tracks you want and select the Send → Bluetooth option. Your watch should be displayed in the device list.
4. Confirm the transfer on the clock (on the screen will appear a notification).
5. After completion, the files will be available in the Local Music section of the watch.

⚠️ Note: When transmitted via Bluetooth, the download speed can be as low as 100–200 KB/s. For an album of 10 tracks (≈100 MB) will take 8-10 minutes. If the connection is interrupted, the watch may not save partially downloaded files.

💡

Before transferring, rename files in Latin (for example, track1.mp3 instead of my track.mp3). Cyrillic in titles can cause reading errors on the clock.

3. Download music via PC (Windows/Mac)

If you have a lot of music or want to manage playlists from a computer, you can use Xiaomi Wear (desktop version) or standard file transfer tools. This method is suitable for users who prefer to work with large libraries.

This will require:

• 💻 Computer with Windows 10+ macOS.
• 🔌 USB-Type-C Cable (to connect the clock to a PC).
• 🎶 Music files in supported formats.

Step-by-step:

1. Connect the Xiaomi Watch S1 to your computer using a cable. The watch should be defined as a removable drive (if this does not happen, check the settings for developers on the watch).
2. Open “This Computer” (Windows) or Finder (macOS) and find the Xiaomi Watch S1 device.
3. Go to the Internal Storage → Music folder. If you don't have one, create it manually.
4. Copy music files into this folder. Avoid nested folders, because the watch may not recognize them.
5. Securely remove the device and restart the watch (press the power button for 10 seconds).

After the reboot, the tracks will appear in the Music menu on the watch. If the files are not displayed, check their format and names (should contain only Latin characters, numbers and signs). _-).

4. Cloud services: how to listen to music without downloading for hours

If you don’t have enough internal memory or want to download files directly, you can use cloud services. Xiaomi Watch S1 supports streaming music through Spotify (with restrictions) and QQ Music (for Chinese firmware), however, this requires an active Internet connection via Bluetooth or Wi-Fi.

Here's how to set up streaming:

• 🎧 Install the Spotify app on your smartphone and log in.

5. Advanced features: download via ADB (for power users)

The built-in memory of the Xiaomi Watch S1 quickly runs out if you download a lot of tracks. Here are a few ways to free up space:

• 🎵 Compress music: Use programs like Audacity or FFmpeg to convert tracks to 128 kbps (saving up to 70% of space).
• 🗑️ Remove the cache: In the settings of the clock (Storage) → Clear cache can be released up to 200-300 MB.
• 📁 Use short names: Files with long names take up more space in the file system.
• 🔄 Rotate playlists: Store only current tracks on your watch, and keep the rest on your phone.

You can also transfer some music to a microSD if your model supports memory cards (check out the specs – the Watch S1 standard does not have a microSD slot, but some modifications, such as the Watch S1 Pro, support memory expansion).
