How to Block a Lost Xiaomi Phone: 5 Ways to Protect Your Data

Lost Xiaomi? Move fast!

Losing a smartphone is stressful, especially if it stores personal photos, access to banking apps or work correspondence. Xiaomi devices have several built-in protection mechanisms, but their effectiveness depends on how quickly you react. The first 10 to 15 minutes after a loss are critical: the faster you lock your phone, the lower the risk of data leakage or unauthorized purchases.

In this article, we’ll look at all the ways you can block a lost Xiaomi, from official Mi Account and Google Find My Device services to operator interactions, and how to track your phone’s location even after resets if Xiaomi’s Find Device function has been activated on it. Importantly, some methods only work when you’re online on your device, so don’t waste time!

The most reliable way is to use Xiaomi’s built-in Find Device feature, which works even if you’re not using it. SIM-map extracted, but requires:

• 🔹 Linked Mi Account (you should have logged in on your phone).
• 🔹 Internet enabled (Wi-Fi or mobile data) on the lost device.
• 🔹 Activated Find Device function in settings (Settings) → Mi Account → Find Device).

If the conditions are met, follow the instructions:

1. Go to account.xiaomi.com and log in.
2. From the menu, select Find Device (or Find Device in the Russian version).
3. The map will show the last known location of the phone, and on the right will be the Lock Device button.
4. Enter a new password to unlock (at least 6 characters) and confirm the action.
