• 🤖 The job of Xiao's voice assistant AI (china-fixed).

It is important to understand that PAI — It's not just one application, it's a whole system-level infrastructure of services, and it's made up of several components, including com.miui.personalassistant (main process), com.xiaomi.ai.asst (voice commands), and background tasks that can appear in the application manager as a "single" or "single" type of application "PAI Service" or "Mi" AI".

How PAI Impacts the performance and battery of the smartphone

The main question that concerns users is: how much PAI Does it load the system? The answer depends on the model of the smartphone, the version. MIUI And most of the time, it works in the background with minimal consumption, but sometimes it can:

• ⚡ Increase battery consumption by 5-15% (especially on low-end models like Redmi) 9A POCO M3).
• 🐢 Slow down when you are actively analyzing data (for example, after installing a lot of new applications).
• 📶 Use mobile traffic for synchronization (up to 50–100 MB per month).

To test the impact PAI On your smartphone, follow the following steps:

1. Open Settings → Battery → Battery Use.
2. Find it on the list "PAI Service or “Personal Assistant".
