How to repair a Xiaomi phone under warranty: the full guide 2026

Introduction: When Xiaomi warranty is valid and when it is not

A broken Xiaomi smartphone is always stressful, especially if it's warranty-based. But not all breakdowns are covered by the manufacturer's official obligations. For example, a cracked screen after a fall or moisture hitting the body automatically voids the warranty even if it's not expired. But software failures, battery failures, or motherboard factory defects are exactly the cases where repairs should be free.

In 2026, the rules of warranty service Xiaomi in Russia and CIS countries have changed: now for some models (for example, Redmi Note 12 Pro+ or Xiaomi 13T) there is an extended warranty on the battery - up to 24 months instead of the standard 12. However, this does not mean that any defect in the battery will be eliminated for free: if its wear exceeds 80% in the diagnosis of the service center, repair can be refused.

Step 1: Check if your fault is covered by a guarantee

Before you take your phone to the service center, make sure the problem is warranty-related.Here is the official list of faults that Xiaomi is required to fix for free:

• 🔋 Bloating or rapid battery discharge (if the wear is less than 80% according to the diagnosis).
• 📱 Self-reboot, “departures” in fastboot or complete shutdown without mechanical damage.
• 🔊 Do not work speakers, microphone or Type-C connector (in the absence of traces of oxidation).
• 📶 Network problems: the phone does not catch 4G/5G, loosen.
• 🖥️ Artifacts on the screen (broken pixels, stripes) if there are no traces of impacts.

Important: if the phone was bought in the official Xiaomi store (for example, on mi.com or from authorized retailers like the Messenger), the warranty is valid even in the absence of a check - it is enough to bind the device to the Mi Account.

⚠️ Note: If you have installed custom firmware (for example, LineageOS or Pixel Experience), the service center has the right to refuse repairs, even if the breakdown is not related to the software.

Step 2: Where to repair Xiaomi under warranty

In 2026, Xiaomi has three types of service centers, and the speed of repair depends on the choice:

To find the nearest service center, go to the official website of Xiaomi Service and enter your city. Please note: some SCs are only open by appointment. For example, in Moscow and St. Petersburg, entry is mandatory for Xiaomi 14 and Redmi K60 models.

💡

If you don't have an official CC in your city, you can mail your phone to the nearest regional center, and you can fill out a form on Xiaomi's website and wait for the packaging instructions, and the delivery is paid by the user, but the cost is reimbursed after the repair.

Step 3: What documents are needed for warranty repairs

Without the right package, repairs will be denied even if they are clearly broken.

Passport of a citizen of the Russian Federation (or another state if repaired abroad)

Check or invoice (if you bought not in the official store)

Phone box (not necessarily, but speeds up the process)

Warranty card (if any)

Linked Mi Account (to confirm the date of purchase)-->

If there is no check, but the phone is purchased from the official store, you can restore the data through Mi Account.

1. Go to the Mi Account website.
2. Go to the Devices section → Shopping history.
3. Find your phone and download an electronic copy of the check.

If the phone is purchased abroad (for example, in China through AliExpress), the warranty in Russia is valid only if the model is officially supplied to our country. For example, Xiaomi 13 Ultra does not have Russian certification, so it will not be accepted in local SCs.

⚠️ Attention: If you have changed IMEI phone (for example, after repair of the motherboard), the warranty is automatically canceled. IMEI *#06# - This must match what is on the box.

Step 4: Step-by-step instructions for handing over the phone for repair

The process of handing over the phone to warranty repair consists of 5 stages:

1. Diagnostics. A CS officer looks at the phone for mechanical damage, and if he finds any signs of falling or moisture, they'll be denied repairs.
2. You will be given a form where you need to specify the model (Redmi Note 11 Pro, POCO X5, etc.), the serial number (you can find it in Settings → About phone) and describe the problem.
3. Signing the admissions certificate, carefully check that the certificate lists all defects, and if the later finds new problems, they may not be fixed.
4. The term depends on the type of breakdown: battery replacement is done in 1-2 days, and motherboard repair - up to 2 weeks.
5. Getting your phone. After the repair, check all the functions (camera, sensors, communications) right in the CC.

If the phone doesn't turn on, bring a charger and cable with you — employees may ask to demonstrate a charging attempt. Models with amoled screens (such as the Xiaomi 12T) sometimes require a "broken pixel" test — it is conducted in a dark room.

Step 5: How Long Does a Repair Take and What to Do When Delayed

According to the Consumer Protection Act, the maximum warranty period is 45 days, but in practice, most malfunctions are fixed in 7-14 days.

• 📅 If the repair lasts more than 45 days, you can request a replacement phone or a refund.
• 💰 For each day of delay, the service center must pay 1% of the cost of the phone (but not more than its full price).
• 📞 If the SC does not answer the calls, write a complaint to Rospotrebnadzor or to the platform "Good Xiaomi".

To track the status of the repair, use:

• Application number (give it when you hand over the phone).
• Xiaomi Repair official website (enter serial number).
• Call in the SC (numbers are indicated in the reception certificate).

Example: Users handed over Redmi Note 10 Pro with a broken speaker. SCC promised to return the phone in 5 days, but the repair was delayed for 3 weeks. After complaining about Good Xiaomi, the customer was compensated 15% of the cost of the phone for lateness.

💡

If the phone was not given on time, record all conversations with the STS (records, correspondence) - this will be useful for a complaint to Rospotrebnadzor.

Step 6: Common User Errors in Warranty Repairs

Many Xiaomi owners lose their right to free repairs due to elementary errors.

• 🔧 Self-repair, even replacing the security glass in an unofficial service will void the warranty.
• 💦 Moisture intake: if the moisture indicator (Liquid Damage Indicator, LDI) It works, repairs will be refused, even if the phone does not sink.
• 🔒 Unlock the loader, install the custom Recovery (TWRP) or root rights stripped of warranty.
• 📦 Loss of a box or check.Mi Account.

Another common problem is that you have a serial number mismatch, for example, if you bought a phone on AliExpress and the seller listed one SN in the check and another on the box, they will refuse to repair it. Always check for SN matching in Settings → About the phone, on the box and in the check.

If you have already made one of these mistakes, try:

• Restore the stock firmware through the Mi Flash Tool (to reset the unlock flag).
• Contact the SC with a request for "voluntary repair" (sometimes they go to meet for a fee).

Step 7: What to do if the warranty is over

If the warranty expired, but the phone broke down due to the manufacturer’s fault (for example, the battery swelled after 13 months), you can try:

1. Some banks (e.g. Tinkoff or Sberbank) give +1 year warranty when buying a phone on credit.

If neither option works, all that remains is paid repairs. Average prices in 2026:

• Battery replacement: 2,500–4,000 ₽.
• Motherboard repairs: 5,000–12,000 ₽.
• Screen replacement: 6,000-15,000 ₽ (model-wise).

⚠️ Warning: Unofficial services often install unoriginal parts (e.g., screens with the worst color reproduction or batteries of lower capacity). Always require a warranty for repairs - at least 3 months.
