Where to buy the original battery for Xiaomi Mi6 in 2026: the full guide

The Xiaomi Mi6, launched in 2017, is still popular with users thanks to its powerful hardware and custom firmware. However, over time, even the best battery loses capacity, and owners face the need to replace it, and the main challenge is finding the original battery, rather than a cheap fake that will last a couple of months.

In this article, we will look at where you can buy a certified battery for the Mi6, how to distinguish it from counterfeit and what to look for when buying. We have analyzed official channels, verified online sites and even options with AliExpress - taking into account all the risks and nuances, you will also learn why the price of the original battery can vary by 2-3 times and what documents must be provided by the seller.

Spoiler: The only 100% reliable way to buy an original battery is to go to a Xiaomi authorized service center, but this is not always possible due to the limited availability of spare parts for older models.

1.Official channels of purchase: Xiaomi stores and service centers

The most reliable, but often the most expensive, way is to buy a battery through official sources. Xiaomi continues to support spare parts for the Mi6, although their number is limited.

  • 🏬 Mi Store brand stores – in some cities (Moscow, St. Petersburg, Yekaterinburg) there are still batteries for old models.
  • πŸ”§ Authorized service centers -- even if they don't have a battery, they can order it directly from the manufacturer β€” 1-2 weekdays.
  • 🌍 Xiaomi official website (Spare parts section) – sometimes there are leftovers, but delivery can take up to a month.

The advantage of this approach is that it guarantees originality and the ability to check the battery before paying. 30-50% higher than third-party sellers, for example, in service centers Moscow battery for Mi6 cost 2500–3500 RUB, while on AliExpress a similar offer can be found for 1200–1800 RUB (but without guarantees of authenticity).

⚠️ Note: In official stores often offer not the original battery, but OEM-similar to the Xiaomi supplier (e.g. Sunwoda or ATL). It's not a fake, but it's not the same battery that came with the phone!

On AliExpress, look for sellers with a rating above 98% and orders from 1000+. Look for the description of the Original Xiaomi Battery or Genuine Mi6 Battery. But even this is not a guarantee - Chinese sellers often use the word "original" to attract customers.

  • πŸ›’ Xiaomi Mall Official Store – official store, but batteries for the first time Mi6 rarely appear.
  • πŸ›’ Mi Global Store – sometimes there are leftovers, but prices are inflated.
  • πŸ›’ HWK Shop – specializes in parts, but you need to check reviews.

3.How to distinguish the original battery from a fake: 5 key signs

Even if you bought a battery from a retail store, it's worth checking it out. Fake Xiaomi Mi6s are so common that some craftsmen refuse to install batteries brought by customers.

  1. The original battery packed in a white blister with the Xiaomi logo and a hologram. QR-Counterfeit products are often sold in a simple bag or box without protection.
  2. Marking: The battery itself must have the model number BM47 (for Mi6) and the manufacturer's logo Sunwoda or ATL. Also check the production date (must be no older than 2022).
  3. Weight and dimensions: The original battery weighs 45-47 grams and is 3.85 mm thick. Counterfeiting is often thinner and lighter.
  4. Contacts: The original contacts are golden, smooth and without ration marks, and for fakes, they are often dull or burrs.
  5. Download Xiaomi Authenticity Check (available only for the Chinese version) MIUI) and scan. QR-If the battery is original, the app will show you a green tick.

If at least one of the points does not match, this is a fake, and you should also be wary if the seller offers a battery with a capacity of more than 3350 mAh (the original capacity is 3350 mAh), counterfeits are often claimed to be 3,500-4000 mAh, but in fact their real capacity does not exceed 2000-2500 mAh.

What happens if you install a fake battery?
Fake batteries not only discharge quickly, but can also: - Bulge after 2-3 months of use. - Cause the phone to overheat (risk of fire!). - Lead to sudden shutdowns with 30-40% charge. - Damage the smartphone power controller, which will require expensive repairs.

4. Hand-buying: Telegram groups, Avito and forums

Sometimes the original batteries are sold on the secondary market, for example, after dismantling smartphones or from the masters who buy parts in bulk. This can be profitable, but the risks are high.

  • πŸ“± Telegram channels like @XiaomiParts or @MiRepair β€” They often post photos of batteries with checkups.
  • πŸ›’ Avito/Yula - look for high-rated sellers and reviews. Ask for a photo of a battery with a weight and a ruler.
  • πŸ’¬ Forums (4PDA, Mi Community – you can find trusted sellers there, but be careful with prepayment.

When buying from hand, never transfer money in advance - use a secure deal or face-to-face meeting.

  • πŸ” Multimeter – voltage at the contacts should be 3.7-4.2 V.
  • πŸ“± AccuBattery applications – after installation, it will show the real capacity.
  • πŸ”Ž Loops - inspect small details (fonts, soldering, markings).

⚠️ Attention: Avito often sells batteries taken from smartphones after replacement, which can wear 20-30%, even if the seller claims otherwise. Always ask for a screenshot from AccuBattery with a Health score).

5. Cost of battery replacement: where cheaper and more reliable

The cost of replacing the battery is based on the cost of the battery itself and the work of the master, depending on the location, the total amount can vary by 2-3 times:

Replacement siteCost of battery (ruble)Cost of work (ruble)Total (rupe)Guarantee
Official Xiaomi service2500–35001000–15003500–500012 months
Informal service1500–2500500–10002000–35003–6 months
Self-sustaining replacement1200–200001200–2000No.

The most budget-friendly option is a self-replacement, but it requires skills and special tools (suction cup, mediator, hair dryer). If you've never taken a smartphone apart, it's best not to risk damaging plumes or displays. In informal services, ask what glue they use for sealing. Cheap glue can detach over time, and the battery will "walk" inside the case.

In official Xiaomi services, you can get a 1-year warranty for replacing the battery, but only if you buy the battery from them. If you bring your own, you will only get a warranty for work (3-6 months).

Make sure the phone is discharged to 20-30% | Prepare the workplace (clean, good lighting) |Buy high-quality glue (e.g. T7000) |Download the disassembly manual for Mi6|Test the new battery for authenticity-->

6. Alternative options: batteries from third-party manufacturers

If you can't find the original battery, you can look at quality analogs from proven brands. They're cheaper, but with the right choice, they'll last almost as long. Mi6:

  • πŸ”‹ Baseus - capacity of 3500 mAh, good reviews, price ~1500 rubles.
  • πŸ”‹ Remax - budget option, capacity 3300 mAh, price ~1,000 rubles.
  • πŸ”‹ ZMI (Xiaomi subbrand - close to the original, price ~1800.

The main rule when choosing an analog is not to chase high capacity. A battery of 4000-5000 mAh will not only fit into the body of the Mi6, but can damage the charge controller. The optimal option is a capacity of 3300-3500 mAh.

Before you buy, check if the battery has a built-in PCB board, without which the risk of overheating and bloating increases significantly, and also pay attention to the number of charge cycles – in quality analogues it is at least 500 cycles.

If you're looking for a lithium-polymer battery, you'll want to go with Li-Polymer batteries, which are safer than lithium-ion batteries and less prone to bloating.

7. Frequent errors in buying and replacing batteries

  • 🚫 Self-replacement without tools, without a suction cup, mediator and hair dryer, you risk damaging the display or plumes.
