Selling a Xiaomi smartphone is not just a matter of price, but also of reputation. Consumers today are scrutinizing devices for hidden issues, from tied accounts to traces of use. Incorrect preparation can lead to conflicts, returns or undervalue. This article will help avoid typical mistakes and maximize the profit of selling your Redmi, POCO or Mi.

We'll look at not only the technical aspects of resetting, deleting data, checking the configuration, but also the psychological aspects, such as why a clean body without scratches increases customer confidence by 30%, or how to take a picture of a device so that it can be bought faster. The instructions are relevant for all Xiaomi models (including the Redmi Note 12, POCO X5 Pro, Mi 13, etc.), regardless of the version of MIUI.

We'll focus on data security, and even after you reset to factory settings, you can recover information, you can learn how to completely erase personal files, untie accounts, and avoid locking your device through Find Device, and at the end of this article, you can check a checklist for quick checks before you meet a customer.

1.Saving important data: what and how to transfer

The first step is backing up. Even if you're sure there's nothing valuable on the phone, check:

• 📁 Photos and videos: Users often forget about screenshots, camera recordings or files in a folder DCIM/.thumbnails.
• 📱 Contacts and Messages: If Google Sync is disabled, data may be lost.
• 🎮 Preservation of games: in Android/data and Android/obb Progress and downloads are stored.
• 📝 Notes and documents: files from Mi Notes, WPS Office or downloaded PDF.

For backup, use:

• 🔄 MIUI Backup: Built-in function in Settings → The phone. → Backup. Save applications, settings and SMS (but not media files!).
• ☁️ Google Drive: syncs contacts, calendars and some app data (include Settings) → Google → Backup).
• 💻 Manual transfer: connect your phone to your PC via MTP (In the notification curtain) and copy the files manually.

💡

If you use Mi Cloud, check that all files are downloaded: open the Files → Mi Cloud → Cloud application. Incomplete sync is a common cause of data loss.

Important! Don't rely on cloud services alone. For example, Mi Cloud only stores files 30 days after deleting your device from your account, and it's better to duplicate data on a physical medium (a flash drive or a hard drive).

2. Deletion of accounts and unbundling of the device

The most common mistake when selling Xiaomi is to forget to untie the Mi Account. If you do not, the buyer will not be able to use the phone: it will be blocked by Find Device (analogue to Find My iPhone).

1. Go to Settings → Xiaomi account.
2. Tap the avatar. → Exit.
3. Enter the password for confirmation.
4. After you exit, go back to Settings → Passwords & Security → Delete your account and delete your profile completely.

If your phone is linked to Google, do the following:

• 📱 Open the Settings. → Google accounts.
• 🔄 Click on the account. → Delete the account.
• ⚠️ After deleting, reset the settings (see next section), otherwise the buyer will not be able to add your account.

Warning: If the phone was purchased on credit or lease, it may be linked to a bank account (e.g. SberBank Online or Tinkoff). Check for such applications and delete them through Settings → Apps.

3. Reset to factory settings: step-by-step instructions

Resets delete all data, but they don't guarantee complete cleanup, like files that can stay in /data or /cachepartition, to erase everything without being able to recover:

Delete all accounts (Mi, Google, social networks)

Keep a backup copy

Charge your phone at least 50%

Disable screen lock (PIN, pattern lock)

-->

Resetting methods:

1. Through settings: Open Settings → About Phone → Reset. Choose Delete All Data. Confirm Action (Password may be required).
2. Through Recovery: If the phone is not turning on or locked: Turn off the device. Press the Power button + Volume up until the Mi logo appears. Select Wipe Data → Wipe All Data. Confirm the reset.

Once reset, the phone will automatically reboot and require you to adjust as new. Don't turn it on - turn it off immediately (press the power button for 10 seconds) so that the buyer can go through the initial setup on their own.

4. Checking of equipment and appearance

Full-fabricated increases the cost of the phone by 10 to 15 percent, and customers often check:

• 📦 The original box: without it, the phone loses up to 20% of the price (especially the Mi 11-13 models).
• ⚡ Charger and cable: even if you have used wireless charging, their presence is mandatory.
• 🎧 Headphones/case: if included (for example, in the Redmi Note 10 Pro).
• 📄 Documents: check, warranty card (if valid).

Evaluate the external condition of the device:

Tip: If you have small scratches on the body, use plastic polymers like Displex, which will bring back the shine and hide the defects, and GOI paste is good for the glass.

5. Performance testing

The buyer will check the phone before buying. To avoid claims, test:

• 📶 Network and communication: Insert two SIM-maps and check the calls/internet. 4G/5G In Settings → SIM-maps and mobile networks. IMEI Not on the blacklist (checking: *#06#).
• 🔋 Battery: Check the wear in AccuBattery (up to 20% normal, higher - lower price) Run the discharge test: from 100% to 0% with active use (normal - 8-12 hours).
• 🎵 Speakers and microphone: Play music at maximum volume - no wheezing. Record your voice message and check for noise.

For a deep diagnosis, use:

• 🛠️ Built-in test: type ##4636## → Testing.
• 📱 Annexes: CPU Throttling Test (for performance testing), Dead Pixels Test (broken pixels).

💡

If the phone has been repaired (such as a screen or battery replacement), honestly report it to the buyer.

6. Optimum price and presentation of the announcement

Prices depend on the state, model and market, and use these services to evaluate:

• 📊 Avito/AVito: filter by "b / y" and "your model".
• 💰 Yula/Yula: average price for the region.
• 🌍 GSMArena: Comparison of characteristics with new models.

Price formula:

Cost of new phone × (1 – 0.15 × age in years) – discount for defects


Example: Redmi Note 11 (new 25,000 ₽, age 1.5, scratches on the body)




25 000 × (1 – 0.15 × 1.5) – 1 500 = 17 500 ₽

How to make an ad appealing:

• 📸 Photo: Take pictures on a white background from different angles (screen, case, box.
• 📝 Description: Specify: Model, memory, color. Condition (e.g., state, "9/10, Small scratches on the frame. Complete ("full, with a check") Reasons for sale ("transition to a new model").
• 🚫 What to avoid: phrases like "everything works," "no complaints" -- they cause distrust. Better write specific pros ("battery holds 1.5 days," "camera without scratches").

Example of a good headline: "Redmi Note 12 Pro 8/256GB, 9/10, full configuration + check, warranty until 2026"
