The BP5E battery model name belongs to a Xiaomi pack. Spare part listings tie it to two recent budget phones, the Redmi A5 4G and the POCO C71. The pack is listed at 5200 mAh typical, and some listings give a rated figure of 5100 mAh at 3.84 V. Both phones come from the same maker group, Xiaomi.
Some buyers write this code as "mi bp5e battery model name". The Redmi A5 does not belong to the older Mi range, so treat that search as meaning a Xiaomi battery and nothing else. You will find the code printed on the cell's sticker. A sealed phone shows it only when a technician has taken off the back cover.
Quick facts
Step by step
Write down the phone name and model number
Open Settings and tap About phone. If the model number is not on the first screen, type model in the Settings search bar and note what it shows.
Compare the number with the BP5E phone family
Listings tie BP5E to model numbers beginning with
25028, such as 25028RN03A and 25028PC03I. A number that starts differently needs a closer look.Ask for the old label to be read
When the back is open, the code
BP5Eshould sit on the pack label with capacity and voltage. Take a clear photo of it before the old pack goes away.Place the new pack next to the old one
Check the code, the outline, the connector and the thickness. A pack that looks right on the box can still be a different shape.
Judge the print and the weight
Good print is sharp and has batch details. A pack that feels very light for a 5000 mAh class battery is a warning sign.
Which phones use the BP5E battery model name
The letters BP are one of the prefixes Xiaomi uses on its pack codes, alongside BN and BM. The prefix points to the maker group, not the phone. For BP5E, listings agree most often on the Redmi A5 4G, and fewer also name the POCO C71. The two phones are close cousins in the budget range, which is why one pack serving both is believable.
| Phone | Model numbers seen | Note |
|---|---|---|
| Redmi A5 4G | 25028RN03A, 25028RN03I | Named in most listings |
| POCO C71 | 25028PC03G, 25028PC03I | Named in fewer listings, so read the label |
| Redmi A3 | Not applicable | Listed under another code, see the BN5R page |
If your phone is a Redmi A3, the BN5R page is the one to check. For the wider Xiaomi family, the Redmi battery model list gathers every code on this site.
Rated 5100 mAh or typical 5200 mAh: which number is yours
This pack carries two numbers, and both are honest. The typical figure of 5200 mAh is what adverts and most spare listings quote. The rated figure of 5100 mAh is the minimum the maker promises, and it is the one that usually appears on the label. Here, 5200 mAh is the typical figure unless the text says rated.
Converting the BP5E rating into watt hours needs one line of arithmetic. Take the mAh, times it by the volts, then shift the answer down by 1000. With 3.84 V, the rated 5100 mAh works out near 19.6 Wh, while the typical 5200 mAh comes to about 20 Wh. The difference is tiny. A pack need not be turned down just because its sticker says 5100.
Do not expect the mAh number to decide screen-on time alone. Screen size, network strength, brightness and which apps you open matter as much, so one pack can give different results in two hands.
Checking the BP5E code before you pay
Most wrong orders come from matching by phone name alone. A repair counter usually has several Xiaomi packs in the same drawer, and the outline of two budget packs can look nearly the same. Use the model number and the old label together, and let the label have the last word.
- Compare the number shown in About phone with the family listed above.
- Read the code, capacity and voltage on the old label.
- Check that the connector and the cable length look the same.
- Ask for a pack with a printed batch detail, not a blank sticker.
When the pack in the phone has already puffed up, leave the removal to the technician. Ask for a photo of the label first, then pick the new pack from that photo.

Similar codes and phone names near BP5E
BP5E is a newer code, so older listings and videos will not show it. Two things cause most mix-ups: a close prefix and a close phone name.
- BP4K and BP9 also start with BP but have their own phone lists. One shared prefix does not mean one shared pack.
- BN5R is the code to check for the Redmi A3 family. Its capacity may look close to BP5E, but the codes differ, so do not swap them.
- The POCO C51 sits near the POCO C71 in name and in price band, yet it has its own battery page.
- The Redmi A5 4G is sometimes called just A5 at the counter. Ask whether the phone is the Redmi A5 or the older Mi A3 or Redmi A3, and see the Mi A3 and Redmi A3 page for those.
A customer brought a POCO phone and asked for a BP pack. The counter had two BP codes in stock. The old label read BP5E, the model number began with 25028, and only then was the pack handed over.
Signs of a tired BP5E pack and the right response
| Symptom | Probable cause | Response |
|---|---|---|
| Charge drops quickly after a normal top-up | Cell capacity has faded over many cycles | Run a health test, then book a swap |
| Sudden power off while 15 to 30 percent is shown | Worn cell cannot supply sudden load | Have a technician test the pack |
| Gap at the back panel or screen lifting | Swollen cell | Pull the charger out of the socket and arrange a service visit on the very same day. |
| Warm phone while idle | Background app or weak pack | Restart, remove the case, recheck after an hour |
A Redmi A5 on a weak tower or running busy background apps can look like it has a worn BP5E when it does not. Read our guide on quick battery drain first. After that, the battery health check shows whether the Redmi A5's BP5E has genuinely lost capacity.
Any BP5E that is puffed up, scorching, seeping or crushed must not stay in the phone. Pull out the charger before anything else. Never squeeze or prod the cell. Set the Redmi A5 on cool tiles and let a service centre inspect it. Many fake packs promise a higher mAh figure than they can deliver, so ask for the printed code BP5E.
Fitting a new BP5E pack the safe way
The Redmi A5 4G and POCO C71 have sealed bodies, so this battery is not made for easy changing at home. A Xiaomi service centre, or a reliable repair shop, can open the back, remove the worn pack with proper tools and clear away the leftover glue. Bring the retail box or the model number, so the staff can pick the right one.
Spot a weak copy by these points:
- It is visibly lighter than the pack it replaces.
- The label is smudged and carries no batch details.
- It claims a capacity well above 5200 mAh, which the pack size cannot honestly hold.
Ask for the old pack back so you can compare. The wider process, from booking to testing, is covered under battery replacement.
Looking after a BP5E battery day to day
Many people at this price level charge the phone all night and use it all day. Most wear comes from heat and from sitting at a full charge for long hours. While charging, put the phone on a firm, open surface, far from pillows and blankets. If the back gets hot, take off any thick case.
The POCO C71 and Redmi A5 should charge on the brick and lead from their own box. Another good charger is fine if its wattage is the same or lower. Replace a C71 cable that warms near the connector. Say the handset powers off too soon even when it was fully charged and restarted. In that case, have the battery tested before you buy anything new.
