Buying a Xiaomi smartphone in the secondary market is always fraught with risks: the phone could be stolen, locked by IMEI or simply worn out more than stated by the seller. One key parameter that helps assess the history of the device is the date of first activation. It shows when the smartphone first connected to MIUI servers after purchase, which indirectly indicates its real age and potential wear of the battery.
In this article, we will look at all the working methods of checking the activation date of Xiaomi, from official methods through phone settings to alternative services via IMEI. You will learn what data you can get for free and what you will have to pay for, and how to interpret the results so as not to run into scammers.
Why is it important to know the activation date of Xiaomi?
The date of first activation is not just a number in the documents, it directly affects several key aspects:
- π Battery status: Even if the seller claims that the phone was on the shelf, the actual age of the battery starts counting from the moment of activation. After 2-3 years, the capacity can decrease by 20-30 years%.
- π Warranty status: In some countries (e.g. the EU), the warranty is counted from the date of activation rather than purchase.
- π¨ Risk of theft or lockdown: If the activation date is significantly newer than the release date (for example, the 2020 phone is activated in 2023), this may indicate flashing after the theft.
- π° Market value: a 2021 smartphone activated in 2026 will cost less than a similar device activated in 2021.
In addition, the activation date helps to identify the replacement of the motherboard β if it does not coincide with the release date (as indicated on the box or in the characteristics of the model), this is a cause for concern. For example, the Redmi Note 10 Pro, released in March 2021, but activated in June 2023, most likely underwent major repairs.
β οΈ Warning: Sellers often reset battery meters through the engineering menu (#4636##), but the activation date is impossible to forge β it is tied to Xiaomi servers and the device is not used for the first time. IMEI device.
Method 1: Verification through MIUI settings (official method)
The most reliable and free way is to use built-in tools. MIUI. It works on all Xiaomi, Redmi and POCO with original firmware (including global and Chinese versions) MIUI 12β14:
- Open the Settings app (cog icon).

- Tap a few times on the line MIUI version until the words βYou are a developer!β appear (this unlocks hidden menus).
- Return to the main settings menu and open Additional β for developers.
- Scroll down to the Device Status block and find the First Activation Date.
The format of the date display depends on the region of the firmware:
- π Global/European firmware: DD/MM/YYYY (for example, 15/03/2022).
- π¨π³ Chinese firmware: YYYY-MM-DD (for example, 2022-03-15).
Make sure the phone doesnβt flash custom firmware (TWRP, LineageOS)
Check your Internet connection (the data is synchronized with Xiaomi servers)
Update MIUI to the latest version via Settings β System Update
Try to change the firmware region to global (if using the Chinese version)-->
β οΈ Note: Some models (e.g. Xiaomi) 12T or Redmi K50) The activation date may be hidden in the menu MIUI Optimization. To open it, type in the Settings search for the optimization request.
Method 2: Checking by IMEI through Xiaomi services
If access to the phone settings is limited (for example, when buying online), you can find the activation date by IMEI, a unique device identifier.
- Find out the phone's IMEI: Dial on the keyboard *#06#, a window with a 15-digit code will appear. Or look at the sticker under the battery (for models with removable batteries). or in the settings: About the phone β General information β IMEI.

Please note:
- β±οΈ First boot time is not always the activation date, but the time of the first successful OS boot after the reset. If the phone was reflashed, it may be later than the actual activation.
- π§ On some models (for example, Xiaomi 13) the engineering menu is blocked β you will need to unlock the bootloader to access it.
What to do if the engineering menu is not opened?
Method 4: Verification through Mi Account (if the phone is tied)
If the phone is linked to a Mi Account, the activation date can be found through the device history, which is suitable if you buy the phone with your hands and the seller is ready to provide access to the account (or you already own the device).

- π If the phone was sold through official channels (such as Mi Store), the date in the account may coincide with the date of purchase.
- π« If the device was reset to factory settings without decoupling from the account, the date in history will remain the same.
- π For Chinese accounts (Mi Account with number binding) +86) may be required to VPN access to complete information.
Yeah, I always check.
I checked 1-2 times.
No, I didn't know about that method.
I trust the salesman at his word.-->
Method 5: Alternative services (IMEI.info, SNDdeep, etc.)
If official methods fail, third-party services that aggregate data from operator and manufacturer databases are paid, but often provide more complete information, including repair and lock history.
Top.-3 service-tested:
- π IMEI.info: Cost: From $2.99 per report. Pros: shows activation date, country of sale, lock status. Cons: no data on Chinese models older than 2020.
- π SNDdeep.info: Cost: From $1.5 per check. Pros: supports Chinese IMEI, It shows the history of the firmware reflashes. Cons: Chinese interface (use translator).
- π‘οΈ Swappa IMEI Check: Cost: Free (Basic Verification), $1.99 for the full report (AT&T, T-Mobile, etc. Cons: not always shows the activation date for Xiaomi.
Example of the report with IMEI.info for Redmi Note 10 Pro:
Device: Redmi Note 10 Pro (sweet)
IMEI: 861234567890123
Activation Date: 2021-07-15
Warranty Status: Expired (24 months)
Carrier: Unlocked
Blacklist Status: Cleanβ οΈ Attention: Third-party services may be wrong! For example, if a phone was activated in China and then transported to Europe, some databases will show the import date as "activation date." Always double-check the data through 2-3 sources.

The most reliable way is a combination of the official Xiaomi service (by IMEI) + verification through the MIUI settings.
What to do if the activation date is suspicious?
If the activation date is questionable, here is the algorithm:
- Compare it to the model release date: For example, Xiaomi 11T Pro released in September 2021. If the activation date is June 2021, it is a clear fake (the phone could not be activated before the release). If the difference between release and activation is more than 12 months, the device most likely lay in stock (the risk of battery aging).
- Check your repair history: Ask the seller for checks or warranty cards. Use services like Apple Coverage (yes, they sometimes work for Xiaomi through IMEI).
Evaluate battery status
- Enter the number ##4636## β Battery Information β See the Wear Level.
- Or use the AccuBattery app (showing real capacity).
Red flags, which are better to refuse to buy:
- π© Activation date is newer than model release date (e.g, POCO F3 2021 activated in 2023).
- π© Difference between activation date and current date is less than 3 months, but battery shows wear and tear of 30%+.
- π© The seller refuses to provide IMEI check-in.
