The BLP915 battery model name points to two Oppo phones, the Oppo A17 and the Oppo A17k, according to most spare part listings. The pack is quoted at 5000 mAh typical and the maker group is Oppo. The same BLP family also covers Realme and OnePlus phones, so the letters alone never tell you which phone you hold.
Buyers type this code in different ways, such as "blp 915" or "oppo blp915". It is printed only on the pack's own sticker, and these phones are sealed, so you see it only when a repairer lifts the back panel. Carry the exact phone model number to the counter as well, because the A17 and the A17k are close cousins with separate model numbers.
Quick facts
Step by step
Find your phone's exact model number
Open Settings, tap About phone and look for the model number, which starts with CPH on most Oppo phones. If it is not on the first screen, type model in the Settings search bar.
Compare it with the table on this page
Check your number against CPH2477 and CPH2471 in the table below. If yours is different, do not assume BLP915.
Ask the technician to show the old sticker
With the back open,
BLP915sits on the label beside the capacity details. Take a photo of it before the pack is put aside.Put the old and new packs side by side
The code, connector shape and outline should match, and the two packs should feel similar in the hand.
Inspect the new label
A genuine label has sharp print and batch details. Turn down a pack with smudged text or no batch marks.
Which phones use the BLP915 battery model name
Codes that begin with BLP are shared across Oppo, Realme and OnePlus. The digits 915 are what narrow the choice. Most listings give BLP915 for the two phones below.
| Phone | Model number | Status |
|---|---|---|
| Oppo A17 | CPH2477 | Given by most listings |
| Oppo A17k | CPH2471 | Given by most listings |
If your phone is the A17k, the Oppo A17k battery page covers it in its own right. To see how the other Oppo codes line up, use the Oppo battery model list.
Capacity: 5000 mAh typical and the number on your label
Ads and shop pages list this pack as 5000 mAh, the usual number you will see. Oppo stickers often carry a second figure that is slightly smaller. This is the rated capacity. The rated value for BLP915 is not confirmed on this page, so trust the number printed on your own sticker.
Watt hours let you compare the energy in different batteries. Put simply, an A17 pack's energy comes from multiplying 5000 mAh by 3.87 V and dividing by a thousand, about 19.4 Wh. Take a sticker voltage of 3.87 V. A 5000 mAh cell then gives roughly 19.4 Wh. Two batteries with the same mAh can still store a little different energy if their voltage is not the same.
Two phones with the same mAh do not last equally. The chip, screen, network use and charger all shape screen-on time and charging time, so do not judge a new pack by hours alone.
Confirming the code before you pay
Do this at the counter, before the back panel is stuck down again. First note the model number from the phone, then ask to see the old sticker. If it says BLP915, ask for a pack with exactly that code.
An owner brought an A17k and asked for "the A17 battery". The shop held a look-alike pack made for another Oppo phone. The repairer opened the back, saw BLP915 on the old pack and ordered by code rather than by name. The new pack seated without force.
Equal mAh with a different code can still mean another size or connector. Never push a connector that does not click in gently.
Keep a photo of the old sticker. If the first pack turns out wrong, the exact code is already in your phone gallery.
Oppo codes close to BLP915
Many Oppo codes sit near each other in number, and print on used labels fades. Read the digits one by one under a bright light, because a 5 can pass for a 6 and a 9 for an 8.
- The codes BLP907 and BLP903 start with BLP9 too, but they are made for other handsets. Never fit them in this phone.
- BLP927 is another nearby number. Open its page rather than guess a shared fit.
- Other budget Oppo phones of the same period are not confirmed as BLP915 here, so rely on the label.
Realme packs also carry BLP codes, so a similar-looking Realme pack is not a safe stand-in.
Signs the BLP915 pack is wearing out
| What you notice | Likely reason | Next step |
|---|---|---|
| Percentage drops fast after light use | Cell worn by years of daily charging | Run a health check, then weigh a new pack |
| A17 dies while still showing charge | Old cell cannot supply the sudden current the chip asks for | Ask a service counter to test the cell |
| Back cover rises or the screen edge lifts | BLP915 has swollen | Stop using the phone and go to a centre at once |
| Phone is warm while idle | A heavy app, weak signal or a bad battery | Restart the phone, remove the cover, and then have it checked |
One app working too hard, or a poor network signal, can often make the charge go down quickly. Start with our fast battery drain guide and spend nothing until you have read it. After that, open the battery health check and run its steps to test the cell on its own.
Stop charging at once if the phone swells, leaks or gets very hot, and do not press it. Place it on a hard surface far from heat, then carry it to a service centre. Counterfeit packs often show a made-up capacity, so pick one whose code, weight and printing are the same as the original.
Fitting a new pack without risk
The Oppo A17 family is sealed. The battery lies under the back cover, held by adhesive, with a delicate connector. Levering it out at home can bend the cell. Give the phone to the brand's service network or a trusted repair shop, along with the model number from the table above.
Once you hold the replacement, look at three points:
- It feels about as heavy as the old pack. A very light one with a big mAh claim is a red flag.
- The label shows clear print and batch details.
- The printed mAh should be close to 5000. If a pack of this size claims far more, the claim is false.
Wider fitting advice is on the battery replacement page.
Daily habits that protect the pack
Phones like these are often bought as a budget handset for the whole family and left on charge from night till morning. Long hours at full charge, together with heat, wear any lithium cell faster. Charge on a table or shelf, never under a pillow or on a sofa, and take off a thick case if the back feels warm.
Use the adapter that was packed with the phone, and swap any lead whose plug end heats up. Charger watts for the A17 and A17k are not confirmed here, so look at the adapter label for your own figure.
Frequently asked questions
Which phone uses the BLP915 battery model name?
Sellers mostly list BLP915 for the Oppo A17 and Oppo A17k, with 5000 mAh as the typical value. Look at the sticker on the old pack from your phone to be sure.

Yes. People only add the space while searching. On the pack the code is printed with no space, so match that printed form.
How many mAh is the Oppo BLP915 battery?
Listings quote 5000 mAh typical. Your sticker may also show a lower rated number, so look at it directly.
Can I use a BLP907 or BLP927 pack instead of BLP915?
Do not assume so. Each code belongs to other phones, and a different code can differ in size or connector. Request BLP915 by its exact code.
Where is the BLP915 code printed?
It is on the battery sticker under the back cover. You see it only when a technician opens the phone, so ask to be shown the label.
What gives away a counterfeit BLP915?
Fakes tend to be lighter, with blurred text, missing batch details and a capacity far over 5000 mAh. Put the new label and weight next to the old pack to compare.
