How To Check Activation Date Of Xiaomi Phone Top [ Essential ]

If the above methods fail, a third-party app can read the hidden system logs.

Open any web browser on your PC or another phone.
Go to: https://i.mi.com
Log in using the same Mi Account that you used on your Xiaomi phone.
Click on “Find Device” (locate your phone on the map).
Look at the top or bottom of the page – you won’t see a date here directly. Instead, click on your device name/model.
Now, look for “Activation time” or “Registration time” (sometimes labeled as “First connected time”).
That timestamp is your official activation date.
