Xiaomi has begun rolling out the Android 16-based HyperOS 3 stable update to global units of the Xiaomi 15. Following earlier updates for the 15T and 15T Pro, this release is currently limited to Mi Pilot members in select European markets but should expand to more regions soon.
Limited rollout now, wider release expected
The stable HyperOS 3 build for the global Xiaomi 15 is being distributed to Mi Pilot participants in some European countries. Xiaomi typically stages these OTA releases, so if you don’t see the update immediately, expect a phased rollout over the coming days or weeks as carriers and regional servers catch up.
What’s inside the update — size, build, and security patch
The global HyperOS 3 package for the Xiaomi 15 is identified by build number 3.0.4.0.WOCEUXM and is roughly 8.2GB in size. It bundles Android 16-based HyperOS 3 along with the October 2025 Android security patch and the platform-level improvements and visual refinements that come with HyperOS 3.
Notes on download size
Download size can vary depending on whether you’re coming from a beta release or a stable channel — some users may see a smaller incremental package, while others will get a full-sized OTA.
Quick tips before you update
- Back up important data to the cloud or a PC.
- Use a stable Wi‑Fi connection — the update is large.
- Ensure at least 50% battery or keep the phone plugged in during installation.
- Free up sufficient storage space to avoid installation issues.
- Check Settings > About phone > System update to trigger a manual check.
As always, staged rollouts mean some users will receive the update earlier than others. If you’re enrolled in Mi Pilot or live in a supported region in Europe, keep an eye on your notifications — HyperOS 3 is on its way to more Xiaomi 15 devices worldwide.
