How to Check If Xiaomi Phone Has Been Repaired: A Complete Guide With Photos and Expert Tips

Buying a used Xiaomi smartphone is always a risk of running into a device with a hidden history of repair. Even if the seller claims that the phone is “like new”, the real condition may differ: a replaced battery, a restored screen after a fall, or unoriginal components. According to statistics, 38% of smartphones in the secondary market have had repairs, but only 12% of sellers honestly report this.

This article will help you identify repair traces on Xiaomi, Redmi and POCO phones, from budget models (Redmi Note 12, POCO X5) to flagships (Xiaomi 14 Ultra, Mix Fold 3). We will analyze unique methods of verification through the MIUI service menus, which are not disclosed even in official instructions, and also show how to recognize counterfeiting of original spare parts.

The IMEI is your Xiaomi passport, which stores the date of production, model and warranty status, but not everyone knows that IMEI can also detect traces of repairs if they were carried out in authorized service centers.

How does it work? When you officially repair it, you put a record in Xiaomi's database that shows the parts you've replaced (like Display Assembly or Battery), which isn't always available through public services, but you can request them through hidden channels.

• 📱 Code #06#: Dial on the phone keyboard #06# – it will appear IMEI. Check it against the number on the box and under the battery (if removable.
