Most listings tie the BN5E battery model name to two 5G phones, the Redmi Note 11 Pro 5G and the POCO X4 Pro 5G. It is a Xiaomi group code for a Li-ion polymer pack with a listed 5000 mAh typical capacity and 3.87 V. Service listings give the model number 2201116PG for the POCO X4 Pro 5G, so compare that number with your own phone.
Many buyers search "note 11 pro battery model" and land on several different phones: the Note 11 Pro 5G, the Note 11 Pro 4G, the Note 11 Pro+ 5G and the Note 11S. They do not all share one pack. One listing also names the Redmi Note 12 Pro 4G, the Note 11 Pro 4G and the POCO F5 for BN5E, which is too thin to rely on. Check the old cell's own label before you order.
Quick facts
Step by step
Read the model number of your phone
Open Settings, then About phone, and note the model number along with the phone name. If you cannot see it, type model in the Settings search bar.
Compare it with the phone table
A POCO X4 Pro 5G is listed with 2201116PG. For a Redmi Note 11 Pro 5G, match the number on the box with the spare part listing. A different number means you need to check the code again.
Have the old cell sticker read
With the back opened by a technician, the sticker should show
BN5Ewith capacity and voltage. Ask for a photo of it before the pack goes in the bin.Hold the new pack next to the old one
Code, outline, weight and the flat connector at the end should all agree. A pack that looks even slightly different is a reason to stop and ask.
BN5E battery model name: which phones use it
The letters BN mark a Xiaomi group pack, used across Redmi, POCO and Mi phones. BN only identifies Xiaomi, so the BN5E phone list has to come from parts records. For BN5E, most listings agree on two phones. Others add more, but with less support.
| Xiaomi model | Model number as listed | Status |
|---|---|---|
| POCO X4 Pro 5G | 2201116PG | Matched by most listings |
| Redmi Note 11 Pro 5G | Varies by region | Most listings agree; check the old BN5E label |
| Redmi Note 11 Pro 4G | Not confirmed | Named by one listing only |
| Redmi Note 12 Pro 4G | Not confirmed | Named by one listing only |
| POCO F5 | Not confirmed | Named by one listing only; do not order on this |
The Note 11S is covered separately on our Note 11S battery page; a similar name does not mean it uses BN5E.
Note 11 Pro 5G, Note 11 Pro 4G and Note 11 Pro+: three phones, three checks
Xiaomi used the Note 11 Pro name on more than one phone, and the 4G and 5G models may hold different cells. Capacity alone is a weak guide, because a pack of similar size can still carry the wrong code or connector.
Work through three checks: Note 11 Pro 5G on the box, the model number in About phone, then the BN5E print on the cell. If any one of them disagrees with the listing, do not order yet.
A customer in a repair shop asked for a battery for a Note 11 Pro and was shown a pack whose box said 5000 mAh. His phone was the 5G version. With the POCO X4 Pro 5G open, the technician read BN5E on the old cell and fitted only a matching pack. The box had never mentioned the code at all.
What the 5000 mAh figure means for BN5E
The 5000 mAh value is the typical capacity, which is what adverts and spare listings quote. Xiaomi stickers often print a rated minimum a little under 5000 mAh, and it can vary between batches. Read BN5E's rated figure from your own pack rather than guessing.
BN5E's watt hours: multiply its mAh by its volts and divide the product by 1000. BN5E at 3.87 V lands near 19.4 Wh, which sellers often round to 19.3 Wh. Both are the same pack described in two ways.
A Note 11 Pro 5G's runtime depends on its chip, 120 Hz display, signal and apps, not mAh alone. Charge speed comes from the 67 W adapter and cable, and the phone caps what BN5E accepts.
Look-alike codes that cause wrong orders
BN5E sits in a crowded run of Xiaomi codes that differ by one letter. At the counter, a worn sticker makes E, F and G look similar, and a wrong pick is easy.
- BN5D, BN5F and BN5G each have their own phones. Open those pages and compare, and do not swap on a guess.
- Codes starting with BM or BP, such as BM5R, belong to other phones even when the capacity is close.
- Another 5000 mAh Xiaomi code may differ from BN5E in plug or shape.
For the whole group in one place, use the Xiaomi, Redmi and POCO code hub.
Signs your BN5E pack is wearing out
| Note 11 Pro symptom | Likely cause | Next step for BN5E |
|---|---|---|
| Note 11 Pro percentage drops in jumps | BN5E worn after many cycles | Check Note 11 Pro health, then book a BN5E |
| X4 Pro 5G turns off at 15 to 30 percent | BN5E voltage dips when the Note 11 Pro works hard | A repair desk can load test BN5E |
| Note 11 Pro 5G screen lifts or back gaps | BN5E has swollen | Stop charging and see a technician that day |
| Phone runs hot with no heavy use | Faulty pack, a bad cable or a rogue app | Remove the cover, try the original cable, get it tested |
An X4 Pro 5G that empties quickly is usually fighting apps or poor reception, so check our drain page before suspecting BN5E. Then use the steps to test battery health to judge the pack.
Treat a swollen, hot, leaking or dented BN5E as a fire hazard. Unplug the Note 11 Pro 5G, place it on a hard surface away from heat and do not squeeze or puncture it. A BN5E copy claiming far beyond 5000 mAh is almost certainly fake, so accept only the same code at a similar weight.
Fitting a BN5E safely
These phones are sealed, and the battery is usually held by adhesive under the back panel. Levering BN5E out at home risks bending it, and a bent cell is unsafe. Let the brand service centre or a reputable local repairer do the job, and tell them which phone it is and show the model number from the box.
Judge the new pack before it goes in:
- A genuine BN5E weighs about what the old one did.
- Expect sharp BN5E lettering plus a batch line.
- The capacity shown should stay near 5000 mAh. A figure like 6000 mAh in the same body is a false claim.
Read our fitting guide for general advice.
After the repair, ask the shop to note the pack code on the bill, so the next visit starts with facts.
Daily care for BN5E in a Note 11 Pro 5G
Heat does most of the damage. Gaming during a charge, a sunny dashboard and a thick cover all heat the Note 11 Pro 5G, so avoid all three. Leaving BN5E at 100 percent for hours each night also wears it sooner.
Use the Note 11 Pro 5G's 67 W boxed charger and cable, or a well made pair rated the same. If a cable gets hot near the plug, retire it. If the X4 Pro 5G still dies at a middling percentage after a restart and full charge, get BN5E tested before buying a new one.
Frequently asked questions
Which phones carry BN5E?

Is BN5E the Redmi Note 11 Pro battery model?
For the Note 11 Pro 5G, most listings say BN5E. The Note 11 Pro 4G and Note 11 Pro+ are separate phones, so read their own cell code.
How many mAh is the BN5E battery?
At 3.87 V, BN5E's 5000 mAh works out near 19.3 Wh. The BN5E inside your phone may carry a marginally lower rated figure.
Is the POCO X4 Pro 5G battery BN5E?
Most listings say yes, and give the model number 2201116PG for that phone. A technician can confirm it when the back is open.
Can I use BN5D or BN5F instead of BN5E?
Do not guess. One letter can mean a different phone, outline or connector. Whatever your old cell says, BN5E or another code, order that.
How do I spot a fake BN5E battery?
Counterfeit BN5E cells weigh less, look blurred, miss the batch line and overclaim capacity. Compare weight and code with the X4 Pro 5G's old cell.
