Xiaomi parts sellers attach the BN59 battery model name to the 4G Redmi Note 10 and to its sibling, the Redmi Note 10S. Both are sold with a 5000 mAh typical pack. Li-ion polymer is the usual cell type for this class of phone.
The word Note 10 is where buyers go wrong. The Redmi Note 10 Pro, the Redmi Note 10 5G and the Redmi Note 10T are different phones, and nothing here says they share this pack. Treat the Note 10 name as a second check after the code on your cell.
Quick facts
Step by step
Find the exact phone name and model number
Open Settings, then About phone, and note the device name and model number. If you cannot see it, type model in the Settings search bar.
Look for the word Pro, 5G or T in the name
A phone called only Note 10 or Note 10S is the one this page is about. If the name carries Pro, 5G or T, go to that phone's own page instead.
Have the technician read the old sticker
Once the back panel is off,
BN59should appear on the cell label with the capacity and voltage. Take a clear photo of it before anything is removed.Compare the new pack with the old one
Put them side by side. The code, the overall size, the connector shape and the weight should all look alike.
Check the print on the new pack
Good packs have sharp text and batch details. Blurry print or a capacity far above 5000 mAh is a reason to refuse it.
Which phones take the BN59 battery model name
Plenty of Xiaomi codes start BN; the letters identify Xiaomi and nothing more. Both are 5000 mAh class phones from the same family, so a shared pack is believable.
| Phone | Status | Note |
|---|---|---|
| Redmi Note 10 (4G) | Matched by listings | Check the Note 10 cell sticker |
| Redmi Note 10S | Matched by listings | Same advice, read the old sticker |
| Redmi Note 10 Pro | Not matched here | Separate page, separate pack |
| Redmi Note 10 5G, Note 10T | Not confirmed | Do not assume BN59 |
The Pro model is covered on its own Redmi Note 10 Pro battery page, and the S model has a Redmi Note 10S battery page where you can compare what that page lists.
What 5000 mAh means for BN59 in a Note 10
BN59's 5000 mAh is Xiaomi's typical figure. No rated BN59 number is confirmed here.
Multiply out BN59's 5000 mAh and 3.87 V and the Note 10 carries close to 19.4 Wh. Should a Note 10S replacement print a lower voltage, it holds less energy than the original BN59.
If it shows another voltage, redo the sum with that value. A Note 10S pack at 3.85 V would hold slightly less, so check volts as well as mAh.Daily run time is not decided by mAh alone. Screen brightness, refresh rate, mobile signal and heavy apps all change it. A phone on weak signal in a basement can drain faster than the same phone on strong signal at a window.
Confirm the code before you pay
Ordering by the Note 10 name alone often goes wrong. Redmi has launched many phones called Note 10, and listings are often written in a hurry. The safest order of checks is below.
- Note the model shown under About phone on the Note 10, or on its box.
- Get the old battery label read once the back is open. It should say
BN59. - Ask for the same code on the new pack, not just the same mAh.
- Compare the BN59 connector and outline with the replacement.
A customer brought a Redmi Note 10 Pro and asked for a Note 10 battery, because that was the name he had typed. The counter had a BN59 pack ready. The old sticker on the Pro showed a different code, so the pack stayed in the drawer and the correct one was ordered.
If your Note 10 sticker shows another code, look it up in the Xiaomi family index.
Codes that look close to BN59
Many Redmi codes share the letters BN and differ by one character. Faint print makes 5 and 6, or 9 and 0, hard to separate. Angle the BN59 sticker towards a lamp or zoom into a photo of it.
- BN5A and BN5J each have their own phone list. Do not treat them as the same pack.
- BN56 and BN5R belong to other Redmi phones. A pack of similar size does not mean a similar code.
- Another phone in the Note 10 range may look the same from outside and still use a different cell.
A 5000 mAh Xiaomi pack with another code may be thicker or use a different plug, pressing on the Note 10's back cover.
Signs the pack is wearing out
| Note 10 symptom | Reason | Next move |
|---|---|---|
| Percentage falls in big jumps | Worn cell after many charge cycles | Test the Note 10, then budget for a BN59 |
| Note 10S shuts off around a quarter charge | BN59 sags when the Note 10S works hard | Have a technician test it |
| Note 10 back or screen edge starts lifting | BN59 has swollen | Stop charging, visit a service centre today |
| Note 10 hot while idle | Worn BN59 or a stuck app | Restart the Note 10, drop the case, test BN59 |
Before blaming the pack, rule out apps and signal by reading the battery drains fast guide. Then use the battery health check steps to judge the pack itself.
A BN59 that bulges, heats strongly, leaks or dents may catch fire. Unplug the Note 10, do not press or bend it, keep it cool and take it to Xiaomi service. BN59 aftermarket packs often overstate mAh, so accept the exact code only.
Fitting a BN59 safely
Glue holds the Note 10 back in place, so let a trained hand lift it. Ask Xiaomi service or a trusted repairer for BN59 and give them the Note 10 model number.
When the new pack arrives, check it for these faults:
- The replacement is obviously lighter than the Note 10's original.
- The label has no batch details and the letters are smudged.
- It claims well past 5000 mAh, which no Note 10 sized cell can manage.
Keep the old pack's photo with the order slip. If the new pack has a problem in the first weeks, the photo proves which code was fitted.

Everyday care for a 5000 mAh Note phone
Note 10 owners lean on video, maps and games, so the phone runs warm. Heat does more damage to the cell than most people think. Remove a thick case for long games, keep the Note 10 out of sun and off beds while charging, and unplug it once full.
The Note 10 and 10S came with a 33 W charger, the best match for BN59. A Note 10S that still shuts off early after you restart it and charge to full points to a BN59 that needs a meter on it.
