The date of the first activation of the Xiaomi smartphone you need to know in three cases: when you buy a used device (to check whether the mileage is “twisted”), to confirm the warranty period or before selling to honestly indicate the real age of the gadget.
Many users mistakenly confuse the activation date with the production date (which is listed on the box or in the battery settings). These are different things: the phone could have been in stock for six months, and was activated only when sold. The difference is especially critical for Redmi Note 12 or POCO X5 models, which are often resold several months after purchase. In this article, all the current methods of verification, including those that work even without a box and a check.
If you bought a phone with your hands, the seller can deliberately hide the actual life of the phone, for example, by resetting the time counters in Settings → Battery, but the date of the first activation is sewn into the firmware and does not reset — it can be pulled out even after 5 years of use, the main thing is to know where to look.
Spoiler: The most reliable method is Xiaomi’s official IMEI service, but it doesn’t work for all regions, but alternatives (via ADB or engineering menus) work 90 percent of the time. Read on to find out which one is right for you.
Xiaomi’s official IMEI service: the most accurate method
The manufacturer maintains a database of all activated devices, and some of that information is available through a public service, and you need the phone's IMEI (a unique identifier like a serial number) to use it, and you can find it in three ways:
- 📱 Dial on the phone keyboard *#06# - a window with a 15-digit code will appear.
- 📦 Look at the sticker under the battery (if the case is removable) or on the box.
- 🔧 Go to Settings. → The phone. → General information → IMEI.
Follow the instructions:
- Go to mi.com/global/verify (works for global versions).
- Enter the IMEI in the verification field.
- Confirm that you are not a robot and press Verify.
- In the results, look for the Activation Date line – this is the date of the first activation.
An important caveat: the service may not show the date for devices purchased in China (the C-suffix version in the model, for example, the Redmi Note 11 Pro+C).
⚠️ Attention: If during the inspection IMEI The service gives an error Device not found, this can mean that the phone is not official (gray import) or its IMEI It was modified software, so you can contact Xiaomi with a check for your purchase.
2. Check through the engineering menu (for advanced users)
The MIUI firmware has an engineering menu that stores technical information, including the date of the first system boot, which works on most models, but it requires caution — don’t change the other settings on this menu!
Step instructions:
- 📱 Open the phone app and dial the code: ##4636##.
- 🔧 In the menu that opens, select the Phone Information (or Phone Information) tab).
- 📅 Scroll down to the Time Since boot block – the date of the first activation in the format can be displayed here. YYYY-MM-DD.
If there is no date, try the alternative code:
##284##It opens the testing menu, where the Single Item Test → Version Info section sometimes displays activation information.
💡
If the engineering menu doesn’t open, check if it’s disabled in the developer settings. Go to Settings → About Phone → MIUI version and tap it 7 times to unlock the developer mode.
3. Analyzing system logs through ADB (for tech-savvy)
The method for those who are willing to connect the phone to a computer. ADB (Android Debug Bridge) allows you to pull out system logs where the moment of the first turn on is recorded, which works even if the phone was reset to factory settings.
What you need:
- 🖥️ Computer with installed Xiaomi drivers (you can download on the official website).
- 🔌 Cable USB (preferably original).
- 🛠️ Utility. ADB (Download as part of Android Studio or separately).
Step-by-step:
- Turn on the phone Debugging over USB (Settings → About Phone → MIUI version → 7 taps → Developer settings → Debugging over USB).
- Connect your phone to your PC and confirm your trust in your computer.
- Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with adb.exe.
- Enter the command: adb shell dumpsys battery In the results, look for the line first_install_time — This is the timetamp (number of seconds with) 1970 To convert it to a date, use this converter.
The critical thing is, if the phone was completely reset through Fastboot, the date in the logs could be reset, and then the method wouldn't work.

4.Serial number check at the service centre
If none of the previous methods worked, the official way is to contact Xiaomi’s service center, and they have access to an internal database that stores the history of all devices sold through authorized channels.
What needs to be done:
- 📄 Find the serial number of the phone (Settings) → The phone. → Serial number or box).
- 🏢 Find out the address of the nearest service center on the official website.
- 📋 Bring your passport and purchase check (if any) without documents, you may be denied information.
Service centers are required to provide an activation date at the request of the owner, but in practice, sometimes you have to insist. If you are refused, refer to the Consumer Protection Act (Article 10 - the right to information about the product).
⚠️ Note: Some "unofficial" service centers may offer paid checks on the database. This is a scam - real Xiaomi centers provide information for free.
5. Indirect signs: how to determine the age of the phone without an exact date
If none of these methods worked, you can estimate the age of the device from indirect data, which doesn't give you an exact date for activation, but it does help you understand how much the phone was used.
What to analyze:
| Parameter | Where to see. | What does it mean? |
|---|---|---|
| Screen time | Settings → Battery → Screen usage time | If more than 1000 hours, the phone has been used for at least 6 months. |
| Battery charging cycles | Settings → Battery → Battery status or via #4636## | Over 300 cycles – battery close to replacement (life ~2 years) |
| Update dates | Settings → About the phone → System update → Update history | The first update is usually installed within a month of activation. |
| Battery status | Apps like AccuBattery or AIDA64 | Capacity below 80% of factory capacity – the phone has been used for more than a year |
For example, if the AccuBattery shows that the battery is worn out by 30% and the charging cycles are 450, the phone has been in use for at least 1.5-2 years, even if the seller claims otherwise.

6. Frequent mistakes and how to avoid them
Many users make the same mistakes when checking their activation date.
- 🚫 Trust the date on the box. It's the date of production, not activation! It can be 1 month to a year.
- 🚫 Use third-party sites to verify IMEI. Most of them show inaccurate data or are fraudulent.
- 🚫 Drop the phone before checking, which can erase the logs needed to analyze through the ADB.
- 🚫 Buying a phone without checking IMEI. Even if the seller shows a “clean” history in the settings, it’s easy to fake.
Another common mistake is to confuse the activation date with the last reset date, for example, after Hard Reset, the phone may show in the settings that it is "new", but in fact it is not. Always double-check the information through 2-3 independent sources.
💡
If the seller refuses to provide an IMEI for inspection or a box from the phone, this is a reason to be wary, most likely, he is hiding something (for example, that the phone is wanted or with a changed IMEI).
