Replacing the battery with Xiaomi Redmi 5: the cost in 2026, where to change and what to look for

Why the Redmi 5 Battery Fails and When to Change It

Xiaomi Redmi 5 smartphone was released in 2017, and even with careful use of its original battery capacity of 3300 mAh by 2026 will inevitably degrade. the average life of lithium-ion batteries is 2-3 years of active use, after which the capacity drops by 30-50%. If your Redmi 5 discharges in a couple of hours, turns off at 20-30% charge or overheats during charging - these are sure signs that it is time to change the battery.

The main symptoms of a “dying” battery:

• 🔋 The phone discharges in 1-2 hours with a minimum load (social networks, instant messengers).
• 🔌 Charging jumps: for example, from 40% immediately falls to 15%, then comes back.
• 🔥 The body is noticeably heated in the battery area even without intensive use.
• ⚡ Charging is extremely slow or interrupted (especially if the cable and power supply are serviceable).
• 🛑 Smartphone spontaneously turns off at 10-30% charge.

Many users try to reanimate the battery with calibration (full discharge/charge), but this does not restore capacity, only temporarily adjusts the controller readings. If the battery is physically worn out, the only solution is to replace, and it is important to understand that cheap analogues from China often have real capacity 20-40% below the declared, which leads to even faster discharge.

Cost of battery replacement in official Xiaomi service centers

The official battery replacement in Xiaomi service centers is the most reliable, but also the most expensive option. As of 2026, the price for work plus the original battery for Redmi 5 is from 2500 to 3800 rubles, depending on the region and the status of the service center (authorized or partner).

What's included in the price:

• 📦 Original Xiaomi battery with warranty (usually 6 months).
• 🔧 Diagnostics of the device before replacement (checking the power chains, charging controller).
• 🛠️ Replacement of the battery with dust and moisture protection (if the body is not damaged).
• 📝 Work warranty card (usually 1-3 months).

⚠️ Some service centers may offer a “original” battery for 1500–2000 ₽ — The official battery for the Redmi 5 (article) MB09) at retail is not cheaper than 2200-2500 ₽. If you are offered cheaper, ask for a certificate of conformity.

💡

Before visiting the service center, back up your data. Sometimes, when you change the battery, you need to reset your settings to the factory, especially if the phone is glitching due to a faulty battery.

Prices in unofficial services: where cheaper and risks

Unofficial workshops and private repairmen offer a replacement battery for the Redmi 5 is much cheaper - from 1200 to 2500 rubles.

1. Battery quality: 90% of the time, you'll be given a Chinese equivalent with a real capacity of 2,000-2500 mAh instead of the 3300 mAh you're told, and it'll last six months.
2. Many workshops only guarantee work (1-2 weeks), but not the battery itself.
3. Risk of damage to the phone: If you open the case in a careless manner, you can damage the plumes of the display or the power/volume buttons.

How to choose a reliable unofficial service:

• 📌 Look for workshops with reviews on Yandex.Maps or 2GIS (rating not lower than 4.5).
• 🔧 Ask what battery is put: if you call the brand Baseus, Remax or Green Cell – it is better than the nameless Chinese.
• 💬 Check if you have a battery guarantee (at least 3 months).
• 📸 Ask for a photo of the original battery before you replace it, so you can make sure it’s actually changed.

Average prices in informal services (2026):

⚠️ Warning: If the master offers to replace the battery for 800-1000 ₽, It's probably just re-solding the contacts of the old battery, or it's going to put the used battery on another phone, and that kind of "repair" will extend the life of the phone for a couple of weeks at most.
