MIUI And it's responsible for what's called "fast applications," which are lightweight versions of programs that run instantly without a full installation, but why is it active even for people who have never used such applications? And why do some users, after turning it off, encounter bugs in the system.

What is Quick App Service and Why You Need It

Quick Apps Service (translated as “fast application service”) is a system component. MIUI, Quick Apps (also known as Instant Apps in Android) are lightweight versions of programs that are designed to be used in the application:

• 🔹 Not required to install it completely via Google Play or Mi App Store
• 🔹 Start almost instantly (weight usually does not exceed) 4-10 MB)
• 🔹 They work without superuser rights (root)
• 🔹 Automatically updates through Xiaomi servers

Example: You can open the Quick App to book tickets, pay for services, or view news directly from your browser or chatbot without installing a full-fledged app. The technology is similar to Google Instant Apps, but implemented by Xiaomi for its ecosystem software. However, here lies the first problem: even if you do not use Quick Apps, the service continues to work in the background, consuming up to the first time. 5-15% Battery charge per month (according to tests on the Redmi Note) 12 Pro+).

• 📶 Periodically contact the network to check for updates (up to 50 MB of traffic per month)

The reason for this behavior is the service architecture, which constantly scans the system for updates for fast applications, even if you don't use them (MIUI 12.5 and below) Quick Apps Service could spontaneously cache fast applications in the background, which led to the filling of memory.

The impact of the service on budget models (for example, Redmi) is especially noticeable. 10A or POCO M4 Pro, where every megabyte of RAM counts.
