Update components on Xiaomi: a detailed guide for users

If you own a smartphone, TV or other Xiaomi smart device, you’ve probably encountered a feature update notification that often raises questions about what’s being updated, why the process takes so long, and can it be canceled? Unlike standard firmware updates (MIUI or HyperOS) that bring new features, component updates work at a deeper level — it affects drivers, core modules and system libraries.

In this article, we’ll explore what a component update in Xiaomi’s ecosystem is, how it differs from regular updates, and why it shouldn’t be ignored. You will learn how to check the relevance of components on your device, what problems can arise when updating, and what to do if the process stalls or ends with an error. TV And smartphones on HyperOS, because they have their own nuances.

Spoiler: It can take up to 30 minutes to update components and reboot the device several times, which is fine if you don't interrupt the process, but there are cases where user intervention is still required. Read on to avoid typical errors.

What is the update of components in Xiaomi devices

The term “Component Update” in Xiaomi refers to an update of low-level system modules that are responsible for:

• 🔧 Equipment drivers – the work of the camera, speakers, sensors, communication module (Wi-Fi, Bluetooth, 5G).
• 🖥️ The core of the system – optimization of power consumption, stability and compatibility with new software.
• 🛡️ Security – fixing vulnerabilities in firmware that are not covered by monthly patches.
• 🔄 Compatibility – adapting the device to new versions MIUI/HyperOS third-party.

Unlike regular firmware updates, which are installed through Settings → About Phone → System Update, components are updated automatically in the background or on request of the system. For example, after a major update MIUI 14 → HyperOS, many users of Xiaomi 12T and Redmi Note 11 received a notification about the need to update components – without this, the new features could not work properly.

It’s important to understand that component updates aren’t always tied to the firmware version. It can come out separately even if your device is already on the latest HyperOS. For example, in 2026, Xiaomi released a component update for the Mi TV Q2 55, which fixed problems with Dolby Vision support — while the firmware version remained the same.
