Xiaomi, Redmi and Poco battery — when to replace and which to take
Replacement batteries for Xiaomi, Redmi and Poco phones (Redmi 4–9T, Redmi Note 3–8 Pro, Mi 8 Lite, Mi 9/9T, Poco F1…), by model. A battery is a consumable: after 500–800 cycles (2–3 years) capacity drops to 70–80 %, the phone dies at 20–30 %, slows in the cold and jumps in percentage. A replacement brings the phone back to life for a fraction of a new one.
What is specific to Xiaomi, Redmi and Poco batteries
Xiaomi batteries carry a BN or BM + number code (e.g. BN5M for the Redmi Note 12) — printed on the old battery and in our listing. The Xiaomi back is plastic or glass, glued, and the battery has pull tabs; replacement takes 20–30 minutes with tools. Redmi Note models with 5000 mAh lose capacity after 2–3 years of 33–67 W fast charging — normal, which is why a replacement battery is the most common repair on those phones.
How to identify the right battery
- The code from the old battery or the exact phone model — our listings carry both.
- Capacity (mAh) equal to the original or slightly higher; suspiciously large figures are not real.
- A protection board (BMS) against overcharging — all ours have one.
- A fresh battery: batteries age on the shelf too, so buy where there is turnover.
Replacement
If the back is lifting or the screen is separating from the frame, the battery has swollen — stop charging and replace it immediately. We replace batteries on the spot in our stores; if you do it yourself, you need a tool kit and patience with the glued back. 12-month warranty against manufacturing defects, free delivery from €10, 24–48 h delivery across Montenegro, cash on delivery.
Frequently asked questions
How do I know the battery in my Xiaomi needs replacing?
It dies at 20–30 %, jumps in percentage, drains in a few hours unused, or the back is lifting (swollen battery — replace immediately). After 2–3 years that is expected.
How do I find the Xiaomi battery code?
On the old battery: BN or BM + number (e.g. BN5M for the Redmi Note 12, BM4J for the Redmi Note 8 Pro). The same battery often serves several models; ours are tied to the phone model too, so the model alone is enough.
Do you replace the battery in store and how long does it take?
Yes — in our stores, usually the same day (30–60 minutes depending on the model). Bring the phone; the fitting price depends on whether the back is glued.
What is the warranty on a battery?
12 months against manufacturing defects. Natural capacity loss with use is not a claim; a battery that loses more than 20 % in the first year or swells — is.
Is battery delivery free?
Yes — delivery is free for orders from €10, and almost every phone battery costs more than that; below €10 delivery is €3. Cash on delivery, 24–48 h across Montenegro, or collect in one of the 7 Xenoni.me stores.
