The BLP781 battery model name goes with the Oppo A52, Oppo A72 and Oppo A92, according to spare part listings. Oppo lists BLP781 as a 5000 mAh typical cell at 3.87 V. Realme and OnePlus use BLP codes too, so the letters never pin down the A52, A72 or A92.
People search this code as "oppo a52 battery model" or "oppo a52 battery model name". Listings for BLP781 name the A52, A72 and A92 together, with CPH2061 quoted as the model number. Spare part listings are not the maker's own papers, so whatever is printed on the cell in your hand decides the matter. BLP781 lies under the A52's back panel, so a technician has to open it.
Quick facts
Step by step
Read the exact phone name and model number
Open Settings, tap About phone and note the name and the model number. If you cannot find the number, type model in the Settings search bar.
Have the old battery label read
Once the technician has opened the back, look for
BLP781on the cell sticker, close to the voltage and capacity lines. Do not lever the pack out on your own.Match the capacity line
The new pack should show a capacity near the old one. A big jump upward, such as a claim far above 5000 mAh, is a reason to refuse it.
Compare connector and shape
Put old and new packs side by side. The flat cable and the plug end should look identical, with the same outline and thickness.
Test the phone after fitting
Charge fully once, then watch the percentage for a day. If the phone still shuts off early, ask the shop to test the charging port and board.
Which phones use the BLP781 battery model name
The BLP prefix covers cells across Oppo, Realme and OnePlus. For BLP781, the listings point to three Oppo phones of the same generation: the A52, the A72 and the A92. All three are listed in the 5000 mAh class, which fits the idea of one shared pack, though only the label can prove it.
| Oppo A series model | Model number | Note |
|---|---|---|
| Oppo A52 | CPH2061 in listings | Matched by listings; some units carry another number, so read About phone |
| Oppo A72 | Check About phone | Matched by listings; the A72 5G is a separate phone |
| Oppo A92 | Check About phone | Matched by listings; the A92s is a separate phone |
| Oppo A53 | Not applicable | Different phone, see its page |
The A52 is the phone most readers hold. If yours is one of the three, ask for BLP781 by its full code and not by the phone nickname, since shops stock packs by code.
Oppo A52 battery model: 5000 mAh typical and what it means
Oppo advertises the A52, A72 and A92 at 5000 mAh typical, the BLP781 figure. Your BLP781 label may carry a marginally lower rated number.
To get energy in watt hours, multiply 5.0 Ah by the listed 3.87 V. The answer is about 19.35 Wh, or 19.4 Wh when rounded. A 5000 mAh pack at another voltage stores a different amount, so mAh alone misleads.
How long an A72 lasts depends on brightness, signal and the apps you leave running, not just BLP781. Charging speed comes from the 18 W adapter and cable, not from the code. A new BLP781 pack brings back the phone's original running time, but it does not add hours beyond that.
Confirming BLP781 before you pay
Never buy BLP781 on the A52 name alone. Three phones share this code in listings, but Oppo sold many A-series phones with similar names, and each has its own pack. Start with the CPH model number in About phone, then have the old cell read once the back is open.
Click a picture of the removed battery's sticker before it goes into the scrap box. That picture settles any argument if the new pack arrives with a different code.
The steps above give the full order. Keep the old pack until the new one works, because a pack that looks right on the counter can still be the wrong plug.
Look-alike names: A52, A53, A54 and A5
Customers often ask for "A5 battery" and the counter hands over whatever is near the shelf. The A52 sits close to several similar names, and none of these is confirmed to use BLP781.
- The Oppo A53 is a different phone with a page of its own: Oppo A53 battery model.
- The Oppo A54 is another phone, covered on its own page.
- The older A5 line is a separate set of phones with codes of their own.
- Codes with close numbers, for instance BLP785 and BLP771, belong to other phones.
A customer arrived with a cracked A52 asking for "the 5000 mAh Oppo battery". Two packs on the shelf both said 5000 mAh, with different codes. The technician read BLP781 off the old cell and handed over only the pack with that code. The capacity line alone could not have separated them.

Signs the BLP781 pack is wearing out
| A52 symptom | Likely reason | Next move |
|---|---|---|
| One day of charge now lasts half a day | BLP781 has aged and lost capacity | Check battery health first, then book a swap |
| A72 goes dark while the meter still reads 15 to 30 percent | BLP781 voltage drops on heavy use | Have Oppo service test the BLP781 |
| A92 back or screen edge lifting | BLP781 has swollen | Unplug the A52 and go today |
| A72 warm while idle | Worn BLP781 or a runaway app | Restart the A72, remove its cover, test BLP781 |
On the A52, start by checking apps and reception with our page on fast drain. Then the health check shows whether BLP781 itself is worn.
A BLP781 that swells, gets very hot, leaks or dents may catch fire. Disconnect the A52 at once, avoid pressing it and get it away from warmth. Get it checked at an authorised service centre. BLP781 knock offs with invented capacities are everywhere, so only the exact code will do.
Fitting a new BLP781 pack safely
Glue holds the backs of the A52, A72 and A92, so BLP781 is not a home swap. Opening them needs heat and the right tools, and the cell can be damaged by a wrong move. Use Oppo authorised service or a reputable workshop and give them the CPH number with the code.
Spot a poor BLP781 copy by these signs:
- It is visibly lighter than the old BLP781.
- BLP781 print is smudged and has no batch mark.
- It claims far beyond 5000 mAh, more than an A52 sized cell can hold.
- The plug end does not match the old one.
See our replacement walkthrough for general fitting advice. Ask for a warranty note in writing, even a short one.
Everyday care for a 5000 mAh Oppo pack
An A72 with BLP781 tends to get long daily use, and heat does it the most harm. Charge the A92 off beds and pillows and out of direct sun. If the phone runs warm while charging, take off a thick cover.
Use the A52's boxed 18 W charger or one rated the same, and bin a cable whose plug has gone loose or hot. Leaving the phone on charge overnight every night keeps the cell at full for hours and speeds up ageing a little, so unplug when you can. A swap is worth planning once a full charge no longer lasts through your normal day.
