How to know the exact date of activation of the Xiaomi phone: official and hidden methods

The date of first activation of the Xiaomi smartphone is a critical parameter that affects warranty period, the possibility of return under consumer protection law, and also helps to identify “gray” devices with a fake history. Unlike the date of production (which indicates when the phone came off the assembly line), the activation date records the moment of first turn on and connect to the network.

The problem is that the manufacturer doesn’t always make this information obvious. Depending on the model (Redmi Note 12 Pro+, POCO X6, Xiaomi 14 Ultra), the MIUI firmware version and the region of sale, the ways of checking may differ, and in this article we will discuss all the current methods, from the standard (via phone settings) to the hidden (via engineering menu and service commands).

We will pay special attention to the nuances: why the date in the warranty card may not coincide with the real one, how to recognize a “overstitched” phone with a reset activation counter, and what to do if the device was bought from hand. All instructions are tested on MIUI 14/15 firmware (Android 13/14) and are relevant for models 2020-2026.

1. Verification through phone settings (official method)

The easiest way is to use the built-in MIUI tools. It works on most modern devices, but may not be available on budget models (like the Redmi A2) or phones for the Chinese market.

Instructions:

1. Open the Settings app (cog icon).
2. Go to the About Phone (or About Device) section.
3. Tap a few times on the MIUI version line until the message “You’re a developer!” appears (this unlocks hidden menus).
4. Return to the main settings menu and select a new option Additional → Special features.
5. Find Activation Date or Device Information – the date of first activation may be displayed here.

⚠️ Note: On some firmware (for example, MIUI Global for the European market), this item can be called First Activation Date or hidden in the submenu of Device Status.

2.Use of IMEI: Verification through Xiaomi services

Each Xiaomi phone is assigned a unique IMEI, a 15-digit code that allows you to track the history of the device, and the official service of the manufacturer allows you to check the activation date, but only if the phone was not flashed to custom firmware (for example, LineageOS).

How to find IMEI:

• 📱 Dial on the phone keyboard *#06# - a window will appear with IMEI (copyable).
• 📄 Look at the device box – the code is listed on the sticker next to the barcode.
• 🔧 In settings: About the phone → General information → IMEI.

Next, go to the official checkout site: https://www.mi.com/global/verify (for global versions) or https://order.mi.com/imei (for Chinese models). Type IMEI and captcha. In the results, search for Activation Date or First Use Time.

Important: Activation date by IMEI Xiaomi may differ from the real one by 1-3 days due to delays in synchronizing data between regional servers.

3. Engineering menu and service codes (for advanced)

If standard methods don't work, you can turn to hidden service menus, which requires caution, because wrong actions can lead to system failure.

Instructions for MIUI 14/15:

1. Open the Phone app and enter the combination: ##4636## This will open the Testing menu.
2. Go to the tab Information about the phone.
3. Scroll down to the Uptime or Uptime block – the date of the first system boot can be displayed here.

Alternative codes (not all models):

• 🔢 ##284## - batch transmission test (sometimes shows the activation date of the communication module).
• 🔢 ##6484## - menu MTK Engineer Mode (for phones with MediaTek chips).
• 🔢 ##64663## – Qualcomm Service Menu for Snapdragon devices).

💡

If the engineering menu asks for a password, try the standard combinations for Xiaomi: 1234, 0000 or leave the field blank. On some firmware, the password matches the last 4 digits of IMEI.

⚠️ Warning: Do not change the parameters in the engineering menu unless you are sure of their purpose! For example, resetting the Battery Stats counter can lead to improper battery operation.

Checking through Mi Account (if the phone is linked to the account)

If the phone has been activated with reference to the Mi Account, the date of the first sign-in can be found through the web version of the service, which works even if the phone was reset to the factory settings, but the account is not untied.

Step-by-step:

1. Go to account.xiaomi.com and log in.
2. In the menu, select Devices.
3. Find your phone in the list and click on it.
4. In the details of the device, look for the First Login Time line or the Date of the first connection.

Limitations of the method:

• 🚫 It does not work if the phone was purchased without reference to the account (for example, in the communication salon).
• 🚫 The date may indicate the first connection to the account, rather than the first activation of the phone (difference of up to 1-2 weeks).
• 🚫 If the device was transferred to another user, the list may display its binding date, rather than the original one.

5. Analysis of system logs (for technically savvy)

Android stores system logs in the back of the system, where you can find a record of the first turn on. This method requires access to ADB (Android Debug Bridge) and is suitable for users familiar with the command line.

Instructions:

1. Install ADB Tools on your computer.
2. Turn on the phone Debugging by USB (Settings → About Phone → MIUI version → 7 taps → Additional → For developers → Debugging by USB).
3. Connect the phone to the PC and enter in the command line: adb shell dumpsys package In the output, look for the firstInstallTime block - this is the time stamp of the first installation of system applications (roughly corresponds to the activation date).

For convenience, convert the time stamp (in milliseconds) to readable format using services like Epoch Converter. For example, the value of 1672531200000 corresponds to January 1, 2023.

⚠️ Note: Logs can be cleared after being reset to factory settings or manually deleted via Recovery Mode. If the command output is empty, the story has been erased.

6. Alternative methods: box, checks, warranty card

If digital methods have failed, look for physical evidence: The manufacturer and sellers often duplicate information about the activation in the documents.

Where to look:

💡 Tip: If you buy a phone from hand, ask the seller to show:

• 📄 Check or warranty stamped shop.
• 📦 Box with intact sticker (IMEI It should match the phone).
• 🔄 SMS history from the operator for the first month of use.

💡

Even if all digital methods show one date and documents another, the data from Xiaomi’s official IMEI website takes precedence.
