When you buy a modern smartphone, every user expects it to work flawlessly for a long time. However, electronics are complex, and even flagship models can fail for reasons beyond the control of the owner. It is in these situations that warranty service, which the manufacturer or the official dealer promises to provide, comes to the fore. It is extremely important for owners of Xiaomi, Redmi and Poco devices to understand how to verify the relevance of this period, so as not to be denied free repairs.
The process of checking the status of the device is often questionable, as global and local versions of firmware, as well as differences in distributors, create confusion. Many users face a situation where the system writes “not found” or shows an incorrect expiration date. This does not always mean that the warranty is over; often the problem lies in the wrong data entry or use of the wrong service. In this article, we will examine all the nuances of how to break Xiaomi’s warranty, what official databases exist and what to do if the device is bought from “gray” sellers.
It's important to understand that timely inspection avoids a lot of problems when you hand over your gadget to the service center. If you're planning to buy used equipment or just want to make sure that your device is authentic, knowing these procedures will be your main trump card. We'll look at working with IMEI, serial numbers and official support portals so that you can act confidently.
Official methods of checking the status of the device
The most reliable method is to go to the source of the primary information, the manufacturer. For Xiaomi, it is a global portal and regional support services that aggregate data on the date of activation and sale of the device. This is the data that engineers will see in authorized service centers when accepting your smartphone. If the database is marked on the expiration date, it will be extremely difficult to prove the opposite without a check with an earlier date.
To start the check, you will need to find a unique identifier for your gadget. IMEI (International Mobile Equipment Identity is a unique number assigned to each communication module. There will be two on dual-SIM smartphones, and they may differ, but any one of them is usually enough to verify the warranty. SN (Serial Number, which is unique to each particular instance of the device.
⚠️ Attention: Enter the data carefully. One error in the number IMEI This will result in a device not found error, which can be misinterpreted as a sign of counterfeit or database problems.
The official website offers several verification tools, the main one being the authentication page, where the system checks the input data against the factory base. If the device is legal and in an active warranty period, the system will display an approximate end-of-service date, but it is worth considering that the global database may be updated with a delay, especially for devices imported into the country by parallel imports.
💡
Always take a screenshot of the test result on the official website immediately after receiving a response, which will be your first proof of the status of the device in the event of a dispute with the seller.
Step-by-step: how to check by IMEI and serial number
To get accurate data, you need to properly extract the identifiers from the Android system installed on your Xiaomi. Don't rely on stickers on the box, as they can be glued or damaged. The surest way is to program a request through the smartphone interface or universal code.
Open the Phone app and dial *#06#. The screen will instantly show a window with technical information. Here you will see the fields IMEI 1, IMEI 2 (if there are two SIMs) and S/N. Write this data down or take a screenshot. An alternative way is through the settings menu: go to Settings → About Phone → General information. In this section, the data is presented in a more structured form, and can be copied with a long press.
☑️ Checking data before entering
Once the codes are received, we go to the official verification site (usually the support.mi.com section or regional equivalent) and enter the 15-digit IMEI code or alphanumeric serial number in the input field. The system will process the request and give the result. If Valid status and future date, your warranty is active. If the Expired status (Istek) is active, but you have recently bought the phone, this is cause for concern.
There is an important caveat for users who have purchased the appliances from outside the official retailer: the warranty start date can be calculated not from the time of your purchase, but from the date of the first activation of the device or even from the date of its production plus a certain period of time. In some regions, 90 days are automatically added to the date of production if the device was not registered online previously, a critical point that is often overlooked.
What to do if Xiaomi fails to break through or the date is incorrect
It is quite common for an official service to issue an error or show a date that was six months ago. This does not always mean that the device is left. Xiaomi’s global databases are sometimes out of sync with real shipments to specific countries, especially in the context of changing logistics. If the system says that the device is not found, try using alternative verification methods, for example, through a Mi Account.
Sign in to your Mi Account at i.mi.com. Devices linked to this account are often displayed on a profile with model and sometimes status. If the phone is displayed correctly, it is exactly original and registered in the brand ecosystem. It is also worth checking the date in the Service & Feedback app, which is pre-installed on all of the company's smartphones. It can display warranty information pulled up from the distributor's local databases.
⚠️ Note: If the warranty end date in the system is in the past, but you bought the phone new, you must keep the check. In the service center, the date on the check will be considered priority, but only if it does not exceed the production date plus 90 days.
In cases where no online service provides a clear answer, direct contact with support remains: write to the chat on the site or call the hotline, providing a photo of the box, check and the device itself. Operators can manually check the status through internal channels that are not available to ordinary users. Sometimes you need to re-assign the device to the region of sale for correct display of data.
Why can't the date be wrong?
Warranty from the store against the manufacturer's warranty
It is important to distinguish between two types of warranty obligations that are often confused by consumers: the manufacturer's guarantee is (promise) Xiaomi to repair its devices free of charge in the presence of factory defects. It operates worldwide (with restrictions by region) and is verified through IMEI. The seller's guarantee is the obligation of a particular store to replace the product or return money if it stopped working, regardless of the reason (within the framework of consumer protection law).
If you buy the device from a “gray” importer, the manufacturer’s warranty may not be valid in your country officially, since the distributor did not pay customs duties and service for this region. In this case, the repair will be carried out by the store itself or partner SCs at your own expense.
For devices purchased at official retail (DNS, M. Video, the Messenger registry, etc.), there is a single system. You can contact any authorized service center, and they will break the device on the base. If the database expired, but less than a year has passed since the purchase of the check (or two, for some categories), you can request repairs by providing the check as the main document.
| Parameter | Official dealer | "Gray" imports | Chinese version (CN) |
|---|---|---|---|
| Xiaomi Guarantee | Acting (global/local) | Often not working. | Only in China. |
| Document for repair | Check + Guarantee pass | Only the store's check. | Not accepted |
| IMEI check | Shows the correct deadline | Could be running out. | Showing the China region |
| Language of the system | Russian out of the box | Russian (Global ROM) | Chinese/English |
💡
Buying from an official dealer guarantees not only the presence of the Russian language, but also the automatic entry of the device into the local base of warranty service.
List of documents for contacting the service center
Even if you successfully beat Xiaomi to the warranty through the site and saw active status, you will need a package of documents to physically receive the service. Just come with your phone and say "I checked online" is not enough. Service centers work strictly according to regulations, and the absence of one document can be grounds for refusing acceptance.
It is important that if there are mechanical damages (cracks, chips, traces of spillage) on the device that are not related to the declared malfunction, you may be immediately warned about the paid nature of the repair or deny warranty.
The main package of documents is as follows:
- 📄 Original check (cash or commodity) with the date of purchase, model name, serial number (or IMEI) Photocopies are often not accepted.
- 📦 Warranty card (if it came in the kit and was filled in by the seller). For Xiaomi equipment, often just a check is enough, since the data is in the electronic database, but the presence of a completed coupon speeds up the process.
- 🆔 The passport of the holder must match the check and the passport if the check is issued to a particular person, and if the check is broken simply as "Buyer", the problems usually do not arise.
- 🔌 Charger, cable and box are often required to be taken with the phone for diagnostics, although by law you can keep them if the fault is not related to them.
A separate issue is the lost check, which can be recovered at the place of purchase by contacting the store's accountancy with a passport and an approximate date of purchase (they can break through the database of broken checks), without a check, it is extremely difficult to prove the date of purchase, and then the "90 days from production" rule, which was mentioned above, comes into force.
Frequent reasons for refusal of warranty repairs
Understanding the reasons for failure will help you avoid them in advance. The most common cause is mechanical damage. If the autopsy detects a crack on the board, traces of oxidation from moisture or a violation of seals (if you tried to open the phone yourself), the warranty is canceled instantly. The moisture indicators (LCI) inside the smartphone change color even from high humidity, which is often interpreted as “pouring”.
The second reason is software interventions: If you unlock a bootloader, install custom backups or unofficial firmware, and that's what caused the failure (e.g., a brick or a burnt-out communication module), the warranties will fail. However, if you have a speaker burnt down or a touchscreen on the stock firmware stops working, the fact that the bootloader is unlocked should not formally affect these nodes, although in practice services often look for leads to failure.
⚠️ Note: Before handing over the phone to the service, be sure to make a full reset (Wipe Data) or extract SIM-card and memory card. The master has the right to conduct testing and your personal data may become available to third parties.
Also, they will refuse repair if the malfunction relates to design features or does not affect the main function of the device, or if the defect is caused by the user's actions (fall, impact, use of unoriginal charging that caused a voltage surge). In controversial situations, the service is obliged to conduct an independent examination at its own expense, but if it proves your fault - you will have to pay for it and repair it.
Return of the device within 14 days
Many users do not know, but they have a powerful right that applies even without checking the IMEI on the site. According to the law (in Russia this is Art. 25 and 18 ZoZPP), you can return a technically complex product, which includes smartphones, within 14 days (excluding the day of purchase), if you simply did not like it (color, size, dimensions), but provided that it was not in use and kept the presentation.
If a defect (marriage) is found in the phone, you can request a refund or exchange within 15 days. After 15 days, a refund is possible only if there is a significant defect or a violation of the repair deadline. During this period, the Xiaomi database check is secondary - the main argument is a check and a defect certificate drawn up at the service center.
To exercise this right, write a copy of the application in the store. One copy to them, the second (your) require you to put a mark of acceptance with a date and signature. If the store refuses to accept the application, go to the post office and send a registered letter with an inventory of the attachment and a notice of delivery to the legal address of the company, which will trigger a legal mechanism that they can not ignore.
