What is considered a warranty case for Xiaomi phones: the full guide 2026

Why Xiaomi’s warranty raises so many questions

Xiaomi smartphones have long been popular because of the combination of price, performance and functionality. But even the most reliable device can fail — and this raises the main question: will the warranty cover the repair, or will you have to pay out of pocket? The answer is not always obvious: the manufacturer clearly regulates which breakdowns are considered warranty and which are not.

The problem is that warranty terms are often written in dry legal language, and service centers often interpret them in their favor. For example, owners of the Xiaomi Redmi Note 12 Pro+ are massively faced with denial of warranty repairs due to alleged “mechanical damage”, although the real reason is a factory defect of the board. This article will help you understand what the warranty covers, how to prove your innocence and what to do if you are denied.

We analyzed Xiaomi’s official documents, user reviews and legal practice on warranty disputes to create the most complete and relevant guide. There are no general phrases here – only specific cases, life examples and instructions for how to proceed.

Xiaomi’s official warranty conditions: what the manufacturer says

According to Xiaomi’s official website, the standard warranty period for smartphones is 12 months from the date of purchase (for batteries – 6 months).

• 📅 Expiration: Starts when the device is activated (first-on dates) rather than purchased. If the phone has been in storage for 3 months, the warranty is reduced.
• 🌍 Regional restrictions: warranty is valid only in the country of purchase.Bought Xiaomi 14 Ultra in China - in Russia it will not be accepted under warranty.
• 🔄 Transfer of rights: no warranty attached to the owner. You can transfer the phone to another person, no reset.

Important: Xiaomi separates the terms "warranty" and "non-warranty": the first are covered free of charge, the second is at the user's expense. The full list of warranty cases is given in the table below.

Note: Xiaomi does not extend the warranty to software failures if they are caused by user actions (for example, installing custom firmware). OTA-Update, this is a guarantee case.

Top.-5 The most frequently recognized cases

In practice, Xiaomi service centers often agree to repair the following malfunctions for free:

1. Marriage of the display: dead pixels, yellowness of the matrix (for example, on Xiaomi) 13T Pro AMOLED-The main condition is the absence of cracks and chips.
2. Battery problems: fast discharge (less than 4 hours of operation), bloating (if not associated with mechanical stress). For example, in the Redmi Note 11 Pro+, a large number of defects of the charging controller were encountered.
3. Faults in the main camera: blurry, artifacts in the photo, broken autofocus. A common problem with the Poco X5 Pro is the "pink shade" in the pictures.
4. Mike failure or speaker: if it stopped working for no apparent reason (no traces of moisture, falls). Xiaomi 12 Lite met a marriage of audio codec.
5. Overheating without load: for example, Xiaomi Black Shark 5 warms to 50°C in plain due to a defect in the thermal paste.

An important point: to confirm the warranty case, the service center is obliged to conduct a free diagnosis, and if you are denied even a diagnosis, it is a violation of the Consumer Protection Act (Article 18).

💡

Always keep the box, check and packaging from the phone - without them warranty repairs may refuse to carry out, even if the breakdown is obviously factory.

Frequent denials of warranties: why and how to challenge

According to statistics, one in three Xiaomi owners face denial of warranty repairs.

• 💧 Moisture: Even if the phone is not sinking, moisture indicators (there are 2-3 of them inside the case) can work from high humidity. 10C Indicators are often falsely triggered due to condensation.
• 🔨 "Autopsy marks: If you have changed your battery or cleaned the charging connector yourself, the warranty is void. Except for official service centers.
• 📱 Root-right or custom firmware: Even if you returned stock firmware, the service center can detect traces of changes in the bootloader.
• 🔋 Bloated battery: automatically considered a consequence of "misuse", although often faulty factory defect controller.

How do you challenge a rejection?

1. Require a written opinion stating the reason for the refusal and the results of the diagnosis.
2. If the cause is questionable (e.g., "mechanical damage" in the absence of cracks), order an independent examination.
3. Contact Rospotrebnadzor or the court. According to statistics, 70% of claims against Xiaomi are satisfied in favor of the consumer.

Hidden nuances: what Xiaomi does not advertise

There are several “gray zones” that the manufacturer does not mention, but which can be used to their advantage:

1. Extended Battery Warranty: If the battery capacity has dropped below 80% in the first 6 months, it is a guarantee, even if the phone is charging "as usual." You can check the capacity through Settings → Battery status.
2. NFC issues: If the module stopped working after the MIUI update, it's a guarantee, as the fault lies with the firmware.A frequent problem with Xiaomi 13 after upgrading to MIUI 14.0.5.
3. Night mode camera marriage: if the photos are green or purple in the dark (sony IMX707 sensor defect in Xiaomi 12S Ultra).

Another life hack: if you are denied warranties for a far-fetched reason, try to contact another service center, and practice shows that different cities can qualify the same defect in different ways, for example, in Moscow, they will refuse for “moisture traces”, and in Yekaterinburg they will accept as a guarantee case.

💡

If the service center insists on "mechanical damage," but you're sure you don't, ask for a diagnostic protocol with a photo of the internal components. Often, "damage" is just a dust or a factory soldering defect.

Step-by-step instructions: how to hand over the phone under warranty

To maximize the chances of a successful warranty repair, follow this algorithm:

Next:

1. Find an official service center on Xiaomi's website. Avoid "partner" workshops, which often impose paid services.
2. Sign up for a diagnosis (some centers can do this online through Mi Repair).
3. When you hand over the device, you will receive an acceptance certificate with a description of the external state and a list of malfunctions.
4. The repair period is up to 45 days, but Xiaomi usually copes in 7-14 days.

If the phone is shipped to another city (e.g. from the regions to Moscow), ask for a track departure number and insurance for the full cost of the device.

What to do if the guarantee is over or denied

If the warranty period has expired or you were denied for a contrived reason, there are several options:

• 🔧 Self-repair: Replacing a display or battery on Xiaomi is cheaper than on a Samsung or iPhone. ~3 000 ₽, battery — ~1 500 ₽.
• 🛠️ Unofficial services: many workshops give their own warranty (usually 3-6 months), the main thing is to check reviews and ask for original parts.
• 📄 Consumer Protection Claim: If the phone breaks down within 2 years of purchase (even after the warranty expires), you can claim repairs at the seller’s expense, proving that the defect was originally made.

FAQ: Answers to Frequent Questions

If your case is not described above, ask the question in the comments, include the phone model, symptoms of malfunction and history of calls to the service, which will help to give an accurate answer.
