Having hunted around for a procedure to move my Xiaomi band 10 over to a new device (after my old phone bloated its battery and pushed out the screen), I couldn't find a really clear guide on transferring everything to a new phone.
Turns out its actually straightforward, at least for the Xiaomi 10 and recent Gadgetbridge versions.
Make sure you have the same version of gadgetbridge on both old and new devices (I used 0.92.0) on both devices).
Pick up your old device and open Gadgetbridge
- Tap the three bars (top left) to open the menu
- Open Data Management
- Export zip
- Upload zip file (has a name like gadgetrbidge_20260707160001.zip) to Google Drive (or some other shared storage).
- Turn off bluetooth on your old device
Pick up your new phone
- Download the gadgetbridge_202607070160001.zip file from Google Drive
- Start Gadgetbridge - if needed, allow all the permissions and get to the main screen
- Tap the three bars and open Data Management
- WARNING : the next step will COMPLETELY replace your gadgetbridge settings and data with the new file
- Import the gadgetbridge zip file you just downloaded.
Gadgetbridge will restart. Now - your new phone will not connect to the band because it is not paired, but the data and devices should be present.
Pick up the Xiaomi 10 band
- Open Settings
- Choose System
- Choose Pair New Phone
Your band will tell you to open the Miband fitness app. Instead, open the bluetooth settings on your new phone. Choose pair device, select the Xiaomi 10 band and follow the instructions on both devices.
Check Gadgetbridge - at this point, for me at least, everything was connected and good to go. All data moved over,
