How to hand over Xiaomi equipment under warranty: from checking the conditions to getting repairs or replacements

Giving Xiaomi a warranty device seems like a simple procedure — until you get into the nuances. Some users get rejected because of scratches on the case, others lose months to send between service centers, and still others do not even suspect that the battery warranty operates separately from the main device. In this article, we will analyze all the stages of warranty service, from checking conditions to receiving a repaired or new device, taking into account the current rules of 2026 and typical errors that owners make.

We analyzed official Xiaomi documents, user reviews on forums (including the official Xiaomi website). 4PDA Mi Community and experience in cooperation with service centers in Russia, Kazakhstan and Belarus. Particular attention will be paid to the hidden points of the warranty agreement, which the manufacturer rarely advertises - for example, how the service will behave if you yourself changed the firmware or installed non-original spare parts. If your Redmi Note 12 is no longer turned on, and Mi Band 8 is not synchronized, here you will find a clear algorithm of actions so as not to lose the right to free repairs.

1. Warranty status check: how to know if the warranty is valid on your device

Before you bring the appliances to the service, make sure the warranty is still valid. Xiaomi has three ways to check, and each of them can give different results - especially if the device was not officially purchased.

The most reliable method is to check the serial number (IMEI for smartphones S/N For other equipment, enter the number in the Serial Number field on Xiaomi's official website, and the system will show the activation date and warranty period. If the device was purchased in China (e.g. via AliExpress or Taobao), the warranty may not work in your country – even if the serial number is “breaking through".

• 📱 For smartphones: dial *#06# - will appear on the screen IMEI (There may be two numbers for devices with two SIM-map).
• 💻 For laptops: the serial number is usually indicated on a sticker at the bottom of the case or in the BIOS (pinch F2 switch-on).
• ⌚ For smartwatches/bracelets: the number can be found in the Mi Fit or Zepp Life app in the About Device section".
• 🔌 For routers and smart equipment: the number is indicated on the case or in the web interface (for example, in Settings). → Status).

If the check on the site does not give results, try alternative methods:

1. Check checks and documents out of the box - there should be a sales date and a store stamp.
2. Look at the Settings. → The phone. → Status (for smartphones) – sometimes it indicates the time of first turn on.
3. Contact the seller (if you bought in the official Mi Store or from partners - Svyaznoy, M. Video). They are obliged to provide information on the warranty.

⚠️ Note: If you bought the device from hand (for example, on Avito or on the Internet). OLX), The warranty is automatically cancelled even if the serial number is "clean." Xiaomi binds the warranty to the first owner listed on the check.

2. Xiaomi Guarantee Terms: What is covered and what you will have to pay for

Xiaomi’s warranty covers manufacturing defects and defects, but does not cover user-related damage. However, the terms in the contract are often interpreted in favor of the service center, for example, “mechanical damage” can be interpreted as a scratch on the screen, even if it does not affect the operation of the device.

Here is what the warranty covers (provided the defect manifested itself without your intervention):

• 🔋 Battery: if it swells or discharges in 2-3 hours (with normal use).
• 📶 Antenna/communication module: network, Wi-Fi or Bluetooth problems (unless connected to firmware).
• 🖥️ Screen: broken pixels, backlights, "yellow spots" (if there were no falls).
• 🔊 Speakers / microphone: no sound, wheezing, noise when talking.
• 🔄 Buttons and connectors: Volume keys do not work, does not charge through USB-C.

This is what they will be denied (even if the device is warranty):

• 💦 Liquid intake (even if the phone did not sink, but was in a wet environment - check the indicators).
• 🔨 Self-repair: if you change the screen, battery or connector - the warranty is removed.
• 📲 Unofficial software: installation of custom firmware (LineageOS, Pixel Experience) or root rights.
• 🔥 Overheating or overloading: if the phone was used for mining or connected to uncertified charging.

⚠️ Note: If you bought a device in Europe or China and are trying to hand it over in Russia, the warranty may not work due to different regional policies.

💡

If the service center refuses to accept the device under warranty, request a written refusal stating the reason, often helping to challenge the decision through a call in support of Xiaomi.

3. Preparation of the device for delivery: what to do and what not to do

Before you bring the equipment into the service, it must be properly prepared, and errors at this stage can lead to loss of data or denial of warranties.

Mandatory steps:

Pay special attention to your Mi Account, and if you don't delete it before you hand it over, the service center can lock the device after repair (by Xiaomi's security rules) to delete the account:

1. Go to Settings → Accounts → Mi Account.
2. Select Delete Account (Password will be required).
3. Confirm the action via SMS or email.

What can't be done:

• 🚫 Trying to repair yourself – even if you just unplug the protective film from the battery, it can cause a failure.
• 🚫 Reset settings via Recovery – this can erase firmware data, and the service will suspect interference.
• 🚫 Install updates at the last minute – if the firmware “flys” during the update, this will not be considered a warranty case.

If the device does not turn on, do not try to "reanimate" it by connecting to charging or heating. It is better to immediately take to the service - there are special equipment for diagnosing "dead" devices.

4.Where to contact: official service centers vs. shops

Xiaomi has two types of warranty points: Authorized Service Centers (ASCs) and Partner Stores (where you bought the device), depending on the type of problem and your location.

Xiaomi service centers are the best option for complex breakdowns (such as a motherboard or battery failure) that work directly with the manufacturer and have original parts.

• ⏳ The repair period can take up to 30 days (according to the law of the Russian Federation - no more than 45 days).
• 📍 Not all cities have ASCs – sometimes you have to send the device by mail.
• 💰 Paid diagnostics (about 500-1000) ₽), if the guarantee is denied.

Partner stores (e.g., Svyaznoy, M. Video, Eldorado) can accept devices under warranty if:

• 🛒 You bought the equipment from them (there is a check or a warranty card).
• 📦 The problem occurred within 14 days of purchase (under the Consumer Protection Act).
• 🔄 This is an explicit marriage (for example, the phone does not turn on from the box).

If you don't know where to turn, use the official service center map on Xiaomi's website. Enter your city and the system will show the nearest ASC with addresses and phones.

⚠️ Note: If you are renting a device to a store under the Consumer Protection Act (within 14 days), you have the right to demand an exchange for a new device or a refund.

5. The delivery process: documents, diagnostics and deadlines

When you bring a device to a service, the first thing you're going to do is fill out a warranty card and provide documents, and without them, the device won't be accepted -- even if the problem is obvious.

List of mandatory documents:

• 📄 Passport (or other identity document).
• 🛒 Check or warranty card (if purchased in the official store).
• 📱 The device itself is complete with charging and cable (if they were in the box).
• 📝 Application for repair (completed on site).

If there is no check, but the device was purchased officially, you can try to restore the check through:

• 📧 Email (if you bought online, check the emails from the store).
• 🏦 Bank statement (if paid by card).
• 📱 Store app (for example, in SberMegaMarket or M.Video store a purchase history).

After receiving the device will be diagnosed (usually 1-3 days).

1. Give the acceptance certificate with a description of the external state of the device (check that all scratches were indicated!).
2. Report a preliminary diagnosis (e.g., "maternal board malfunction").
3. Name the period of repair (by law - no more than 45 days).

If the diagnostics show that the problem is not warranty, you will be billed for repairs, you have the right to pick up the device without payment - but only if you did not sign the consent for paid repairs in advance.

💡

Always require a delivery certificate with the signature and seal of the service center. Without this document, you can not prove that you have handed over the device for repair if it is "lost" in the service.

6.What to do if the warranty is denied or the repair is delayed

Warranty denials are a common problem, especially if the device wasn't bought in a store, but even then you have leverage.

Common reasons for refusals and how to challenge them:

• 🔧 "Autopsy marks" → Demand proof (photo, forensic report) If you didn't repair the device, the autopsy could have been factory-made.
• 💧 "Moisture intrusion" → Check the moisture indicators (they should be red); if the indicators are white, demand a rediagnosis.
• 📱 "Unofficial firmware" → If you have not installed custom software, ask for a firmware log.

If the service center delays the repair (more than 45 days), you have the right to:

1. Require the provision of a swap device for the period of repair (according to the law of the Russian Federation).
2. Write a claim to the director of the service center with the requirement to speed up the process.
3. Contact Rospotrebnadzor or the court if the terms are violated without objective reasons.

If you are denied without reason, write a complaint:

• 📧 To email support Xiaomi: support@mi.com (for Russia or through the form on the website.
• 📱 In the official social networks of the brand (Vkontakte, Telegram – often respond faster than support).
• 🏛️ The Consumer Protection Society (e.g., the OPP).

7. Alternative options: if the guarantee has expired or refused

If the warranty expires or you are denied free repairs, don't rush to buy a new device.

Official paid repairs:

• 💰 The cost of repairs in the ASC Xiaomi is usually 20-30% lower than in third-party workshops.
• 🔧 Original parts are used (unlike the “gray” services).
• ⏳ Repair period - 7-14 days.

Informal service centres:

• ⚡ Faster and cheaper, but the risk of running into poor quality parts.
• 🔍 Look for workshops with good reviews on Yandex.Maps or 2GIS.
• 📌 Ask if you have a warranty for repairs (good workshops give 3-6 months).

Self-repair (for experienced users only!):

• 🛠️ For Xiaomi, it is easy to find parts on AliExpress (e.g. screens, batteries, connectors).
• 📺 YouTube has detailed guides on disassembling most models (see "[model] teardown" on request").
• ⚠️ Risk: Lose the remaining warranty (if it is still valid) and can damage the device even more.

Software problems (if the device is glitchy but not physically broken):

• 🔄 Reset to factory settings: Settings → Additionally. → Recovery and discharge.
• 📥 Flashing through Mi Flash (if the phone doesn’t turn on or hovers on the logo).
• 🛡️ Removing viruses through Malwarebytes or built-in antivirus.

If the device is not repairable, consider the options:

• 🔄 Trade-in: many stores (for example, the Messenger) accept old equipment in the account of buying new.
• 💰 Sale for spare parts: on Avito or Yula, you can profitably sell a faulty smartphone (for example, Redmi with a broken screen, but a working motherboard).
• ♻️ Recycling: some cities have electronics reception points (e.g. Ecotechnologies in Moscow).
