«Xiaomi activation service» (com.xiaomi.mi_connect_service) — This is a system application that is part of the firmware MIUI and is responsible for:
- 🔑 Activation of the device at the first turn on (binding to the Mi Account).
It's basically a bridge between your smartphone and Xiaomi's servers that enables key ecosystem functions to work.
- 📱 Use Mi Cloud for backup.
- 🔒 Unlock your phone through Find My Device after resetting.
- 🔄 Get OTA-firmware update.
But many users suspect the service of collecting personal data and consuming resources. Is that really true?

- 📡 Consume traffic (up to 50–100 MB per month for synchronization).
- 🚫 Block certain activities (for example, installing third-party firmware).
According to tests on Xiaomi 12 Pro and Redmi Note 11, the service can take up to 3-5% of battery charge per day when you actively use synchronization. on older devices (for example, Redmi 4X), this value can reach 10-15%.
| Model of the device | Battery consumption (per day) | Traffic (per month) | Impact on productivity |
|---|---|---|---|
| Xiaomi 13 Ultra | 1–2% | 30-50 MB | Invisibly. |
| Redmi Note 12 Pro+ | 2–4% | 50–80 MB | Light braking. |
| POCO X3 Pro | 3–6% | 70-100 MB | Noticeable lags when multitasking |
| Redmi 9A | 5–10% | 80–120 MB | Strong brakes. |
