How much does it cost to replace the battery on Xiaomi Redmi 6 in 2026
Xiaomi Redmi 6 was released in 2018, and after 5-6 years of operation, its battery inevitably loses capacity. If your device discharges in half a day, turns off at 30% charge or requires constant recharging, it's time to think about replacing the battery. But how much will it cost in 2026? Prices vary from 800 to 3500 rubles, depending on the method of repair and the quality of components.
In this article, we will look at all the options, from official service centers to self-replacement, you will learn where it is cheaper, what pitfalls await when buying a non-original battery, and how to check that you have installed the exact battery for which you paid, and also a list of proven services in Moscow, St. Petersburg and the regions with current prices for June 2026.
Important: Redmi 6 has a non-removable battery, so replacing it requires disassembling the case. If you've never repaired your smartphone, you'd better trust the professionals. But there's a nuance here, too: some services save on glue or seals, which can lead to dust or moisture.
Xiaomi vs. Unofficial Workshops: Price Comparison
The most reliable, but also the most expensive option is to contact an authorized service center Xiaomi, where you are guaranteed the original battery, the preservation of the sealed housing and the official guarantee for work (usually 6 months).
- 🔧 Original battery (article) MBJ4059) — 1800 to 2,500 rubles
- 🛠️ Replacement work – from 1000 to 1500 rubles
- 📋 Diagnosis (if required) – 300-500 rubles
Total: 2800-4000 rubles depending on the region. In Moscow and St. Petersburg more expensive, in small cities you can meet 3000-3500 rubles. But there is a catch: official services often refuse to work with phones older than 3 years, citing the lack of spare parts. Redmi 6 just falls into this category — it was withdrawn from production in 2020.
The alternative is informal service centers, where prices are lower, but there are higher risks.
- 🔋 Non-original battery (Chinese analogue) - 600-1200 rubles
- 🔧 Work - 500-1000 rubles
- ☑️ Warranty - from 1 to 3 months (if given)
Total: 1100-2200 rubles. The savings are obvious, but there is a risk of running into a battery of poor quality, which will last six months.
Self-Replacement: Is the game worth the candle?
If you have experience disassembling phones and the necessary tools, you can save on work and change the battery yourself.
- 🛒 Original battery (with Aliexpress) – 1200-1800 rubles
- 🛒 Analogue of high quality (Baseus, Remax brands) – 700-1200 rubles
- 🛒 Budget analogue (no-name) – 400-800 rubles
- 🔧 Set for disassembly (suction cup, mediator, screwdriver) - 200-500 rubles
That's 600 to 2,300 rubles if you buy everything from scratch, but consider that Redmi 6 requires you to unplug the display module, which without experience can damage the plumes or matrix, and you also have to apply new glue for sealing yourself, otherwise the phone will lose protection from dust and moisture.
⚠️ Warning: If you replace yourself, you lose the warranty (if it is still valid) and risk damaging other components, such as tearing off the antenna contact or the fingerprint scanner plume.
If you do, here is a step-by-step instruction:
Buy a battery with a capacity of at least 3000 mAh (original - 3000 mAh)
Prepare the workplace: clean surface, good lighting
Download the Redmi 6 disassembly manual (e.g. on iFixit)
Turn off the phone and take it out. SIM-pre-work-card
Use plastic tools to avoid damaging the body-->
You can find detailed videos on the demolition on YouTube (see "Redmi 6 battery replacement"), but remember, if the phone doesn't turn on or overheats after the replacement, it's your fault.
How to check if you have an original battery?
One of the most common scams in service centers is installing a cheap battery instead of the original battery, but at the price of a branded battery. How can you not become a victim of fraud?
First, check the labeling. The original Xiaomi Redmi 6 battery should have:
- 🏷️ Inscription MI or Xiaomi with the brand logo
- 📝 Articulum MBJ4059 or BH43 (supplant NFC)
- 🔢 Serial number and production date (e.g, 2023-05)
- 📏 Capacity 3000mAh / 11.4Wh (analogues often indicate inflated values like 3,500 mAh)
Second, use special applications to diagnose the battery:
- 📱 AccuBattery (shows real capacity and wear)
- 📊 AIDA64 (displays the technical data of the battery)
- 🔋 CPU-Z (checks voltage and temperature)
If the app shows a capacity of less than 2800 mAh or wear more than 5% during the first charge cycle, you have been installed a fake. Demand a replacement or a refund!
⚠️ Warning: Some services deliberately drop the charge cycle counters in the firmware to hide the switch. Check the battery immediately after repair before signing the acceptance certificate.

Where to buy a battery for self-replacement?
If you're going to change the battery yourself, the key is to find a quality part.
- 🌐 AliExpress is the biggest choice, but a long wait (2-4 weeks).Look for sellers with a rating above 98% and reviews in Russian. The average price of the original battery is 1200-1500 rubles.
- 🛒 Beru.ru / Ozone - fast delivery (2-5 days), but prices are higher by 20-30.
- 🏬 Local parts stores – in major cities there are specialized points (for example, FixPrice Service or Mobile Driver) Prices are comparable to AliExpress, but you can check the product before buying.
- 🔧 ServeHere or iParts are a warranty parts ordering platform that sells both originals and certified counterparts.
Beware of fakes, here are the signs of a poor battery:
- 🚫 No marking or it is erased/blurred
- 🚫 Weight less than 50 grams (original weight) ~58-60 g)
- 🚫 Contacts oxidized or bent
- 🚫 The seller does not provide a check or guarantee
If you buy on AliExpress, pay attention to the description: the original battery must have a factory packaging Xiaomi with a hologram and a silk. QR-authentication.

Frequent battery replacement errors and how to avoid them
Even if you've entrusted the repairs to professionals, you're at risk of problems after the replacement, and here are the most common mistakes and how to prevent them:
- The battery is calibrated wrong. After you change the battery, you have to train it to completely discharge, then charge it to 100% without interruption, and if you don't, the phone will show the wrong percentage of charge.
- Train damage. When you disassemble Redmi 6, it's easy to hit the plume of the fingerprint scanner or the display, and that will cause the sensor to fail or the artifacts on the screen. Solution: ask the wizard to use plastic blades, not metal blades.
- Bad sealing. If the body creaks or the gaps get bigger after the repair, the master has not properly pasted the display, it will lead to dust and moisture. You need to reassemble!
- Using an incompatible battery, like a Redmi 6A (3,000 mAh, but different connector), which either won't hold a charge or won't work at all.
To minimize the risks, ask the repairman the following questions before the repair begins:
- 🔹 "What battery will you install? Show me the package."
- 🔹 "Do you give a job and part guarantee? How long do you have a job guarantee?"
- 🔹 "Do you use a new glue for sealing?"
- 🔹 "Can I check my phone before paying?"
💡
If the battery is replaced, the phone is more likely to discharge, warm up or spontaneously shut down, this is a sign of defect or improper installation.
