Xiaomi MIX Fold 3 (codename: babylon) is a premium foldable powered by Snapdragon 8 Gen 2, and it receives HyperOS updates through stable builds like OS2.0.x.x.VMVCNXM. However, real-world user feedback around HyperOS updates often mentions problems like overheating and unusually fast battery drain, plus recurring connectivity/charging/screen-recording bugs highlighted in Xiaomi’s weekly bug reporting.
Installing the correct OS2.0.209.0.VMVCNXM fastboot package can help by upgrading you to a newer stable build and reinstalling core system partitions (a common fix path for software corruption, boot issues, and persistent instability after updates).
Warning (Xiaomi MIX Fold 3 / babylon): Flashing firmware is advanced and risky. Wrong ROM/region/variant or improper steps can brick the device, wipe data, cause boot failure, instability, security issues, and void warranty. Files/tools are provided “as is” with no warranties; authors/providers accept no liability for damage or loss. Verify exact model/region, back up data, and proceed only if you understand flashing—at your own risk.

Why This Firmware Matters
Across HyperOS user discussions, one of the most repeated complaints after certain updates is severe battery drain and overheating during normal tasks. Xiaomi’s own weekly bug-report posts also routinely track issues such as Wi‑Fi problems, charging anomalies, and screen recording bugs (with fixes arriving in later builds), which is why moving to a newer stable build can be worthwhile when an older one is misbehaving.
- Performance & stability refresh: A fastboot ROM reinstall replaces core system components, which can help when the OS was damaged by a failed update, mod, or incomplete OTA.
- Bug-fix uplift: OS2.0.209.0.VMVCNXM is listed as the latest stable HyperOS build for MIX Fold 3 (babylon) in China channels, meaning you’re not stuck on earlier 2.0 builds that may carry older bugs.
- Cleaner recovery path: When settings tweaks don’t solve persistent drain/heat or random glitches, reflashing the official package is a common “reset-to-factory-software” approach that users rely on before hardware servicing.
