Xiaomi Redmi 4X has long been a legendary budgetary smartphone, but even the most reliable devices eventually deplete the power source. If your phone stopped holding a charge, quickly discharges in the cold or turns off at 20% charge, then it’s time to replace the battery. This is a standard procedure for gadgets that are several years old, and it allows you to extend the life of the device for another 1-2 years of active use.
In 2026, the question of replacement costs is particularly acute as it becomes more difficult to find a new original battery and the market is flooded with cheap copies. The cost of repairs is not only the cost of the part itself, but also the complexity of dismantling, the quality of materials used and the skill of the master. In this article, we will discuss current prices, the risks of self-replacement and how not to run into poor service.
Should we change the battery in 2026 or should we buy a new phone? For many users, the Redmi 4X is the second working device or phone for older parents, where reliability and simplicity are important, and in such cases, replacing the battery is the most rational economic decision to avoid the cost of buying a new device and transferring data.
Factors affecting the final cost of repairs
The first thing to understand is that the price on the service center price list is just a starting point. The total amount you will be told after a diagnosis may vary depending on several critical parameters. The main factor is the type of battery. Original batteries, even those released a few years ago (New Original), cost 2-3 times more than quality copies of the AAA class or cheap counterparts.
The second important aspect is the condition of the body and plumes. If the previous "master" has already opened the phone and damaged the display plume or broke plastic latches, repairs can go up in price. In the Redmi 4X, the back cover is metal, but it is held on glue and screws, and a sloppy opening often leads to deformation of the frame. Also, the price is affected by urgency: the service "repair with you" usually costs more than the delivery of the device for several days.
In large megacities, rent and pay for the masters are included in the cost of parts, so regional service centers may have lower prices, but the choice of spare parts is often limited. Always check whether the amount announced includes diagnostics and inspection of other nodes of the phone, as some services charge a fee for this, even if you refuse to repair.
Current battery prices and work in 2026
The spare parts market for Xiaomi in 2026 The year is clearly segmented. 4X (battery-model BN41) You can find deals in three main price categories. Cheap copies often have real capacity. 1500-2000 mAch instead of the declared 4100 It's a mAh, which reduces the value of the replacement to zero. Originals are harder to find, they often come in factory packaging with a hologram and a snippet. QR-code.
The average battery replacement job is 30-50% of the cost of the part itself if you buy it from the service. If you bring your battery, many centers will refuse warranties or charge a fixed rate for "installation of customer parts." Below is a table with indicative prices relevant for the current period.
| Type of battery | Capacity (claimed) | Part price (ruble) | Replacement price (ruble) |
|---|---|---|---|
| Copy (Class C) | 4100mAh | 400 - 600 | 900 - 1100 |
| Quality Copy (AAA) | 4100mAh | 800 - 1100 | 1400 - 1700 |
| Original (New/Ref) | 4100mAh | 1500 - 2000 | 2200 - 2800 |
| Original (Storage stock) | 4100mAh | 2200 - 2800 | 3000 - 3500 |
Note that prices can fluctuate depending on the exchange rate and suppliers. The guarantee for cheap copies is usually 14 days, whereas for original services you give from 3 to 6 months. The savings of 500 rubles when buying the cheapest battery often turn into a re-replacement after a month, which eventually will be more expensive.
💡
The best choice for price/quality ratio in 2026 are high-quality copies of the AAA class from proven brands like Nohon or Baseus, as it is almost impossible to find a new original.
Self-Replacement: Is the Risk Worth the Cost?
Many users, seeing the cost of batteries on marketplaces, think about self-replacement. Theoretically, Redmi 4X is not a complex device in disassembly: there is no glued display around the perimeter, like in flagships, but there are nuances: you will need a set of screwdrivers (cross and star), a plastic spatula and, preferably, a hairdryer or heating platform for softening the glue under the lid.
The challenge is to take the metal back cover off neatly, and it's based on a two-part glue, and if you don't warm enough, you can bend the frame or break the plastic, and if you heat it too much, you can damage the plumes or the battery itself, which is fire-prone, and you also have to be very careful with the fingerprint scanner plume, which is often glued to the lid and very easily breaks when you're not moving.
☑️ What you need for a self-replacement
If you don’t have experience in electronics repair, the savings of 500-800 rubles may not cost a damaged plume or broken camera glass. The cost of replacing a scanner plume or camera module may exceed the cost of replacing the battery itself in the service.
