Spare part listings tie the BLP805 battery model name to two phones, the Oppo A53 and the Oppo A32, with a Li-ion pack of 5000 mAh typical capacity. The maker group is Oppo, and the same BLP letters are also used for Realme and OnePlus packs. Some listings stretch the phone list to many more Oppo models, so this page keeps the firm matches apart from the doubtful ones.
People type this code as "oppo blp805 battery model name" or "blp 805", and both mean the same pack. The code is printed on the battery's own label, under the back cover. On a sealed Oppo the phone has to be opened before anyone can read it, so the phone name and model number are your first clue.
Quick facts
Step by step
Copy the exact phone name and model number
In Settings, open About phone and copy the device name and model number. If it is not on the first screen, type model in the Settings search bar.
Get the old battery label read
Once the back is open, the technician can read
BLP805on the label. Do not pull or peel the pack yourself, because adhesive holds it down.Lay the new pack next to the old one
The code should be identical, the capacity close, and the outline and connector end the same shape.
Inspect the print and feel the weight
Look for sharp print and batch or date marks. Hold it against the old pack. A light pack that claims a bigger mAh number is a warning sign.
Which phones use the BLP805 battery model name
BLP is the letter group Oppo uses for packs in Oppo, Realme and OnePlus phones. The letters alone do not name a phone. For BLP805, the clearest agreement across listings is the Oppo A53 (the 4G phone) and the Oppo A32. Several listings add more names, and those need care.
| Phone | Status | Note |
|---|---|---|
| Oppo A53 (4G) | Named in most listings | Capacity listed: 5000 mAh typical |
| Oppo A32 | Named in most listings | Shown with the same pack as the A53 |
| Oppo A33, A53s | Named in some listings | Not confirmed, read the old label |
| Oppo A54, A74 5G | Named in some listings | Not confirmed, see the A54 page |
| Oppo A16, A16s | Named in some listings | Not confirmed, see the A16 page |
One long phone list pasted on every pack proves nothing about fit. Your own old label has the final word. The pages for the Oppo A54 and the Oppo A16 give the codes for those phones.
BLP805 capacity: the 5000 mAh figure and what it means
Most listings state 5000 mAh, and that is the everyday headline value. Oppo packs often carry a second, somewhat smaller number on the label, called the rated or minimum capacity. That rated number is not confirmed for BLP805, so copy it from the pack in your hand.
Some listings give the voltage as 3.87 V, while others show a higher number that looks like the full-charge limit. To turn mAh into watt hours, multiply by the nominal voltage and divide by 1000. At 3.87 V, a 5000 mAh pack works out to about 19.4 Wh. Treat that as a rough guide until you see the voltage printed on your own label.
Weight is another handy check, but listings for this code disagree on it, so ignore any gram figure in an advert. Compare the new pack with the old one in your hand instead.
Checking the code properly before ordering a pack
The phone name by itself is not enough to buy on. The name Oppo A53 was used for a 4G phone, a 5G phone and the A53s, and these may carry different packs. Start with the model number under About phone, then confirm with the label on the old battery.
- Take a clear photo of the old label before the pack leaves your hands.
- Match the whole code, every digit. A single digit changes the phone list.
- Check that the connector end and the outline match the old pack.
An Oppo A53 owner brought a replacement marked BLP803, because the print looked close. The technician read BLP805 on the old label and refused the swap. The pack went back and the exact code was fitted instead.
Look-alike codes that get confused with BLP805
BLP codes run close in number, and print on small stickers is hard to read. BLP803 is one digit away, so open BLP803 and read its phone list before you accept any pack carrying that number.
- The older Oppo A5 and A9 pair is listed with
BLP727, a different pack. See BLP727 and the Oppo A5 page. - Equal capacity does not mean equal fit. Many Oppo packs are 5000 mAh yet carry different codes.
- On worn labels the digits 5, 6 and 8 blur together, so read them in bright light.
For every Oppo, Realme and OnePlus code in one place, use the Oppo battery model list.
Signs that the pack is failing
| Symptom | Probable cause | Next step |
|---|---|---|
| Charge falls fast within a few hours | Cell aged by many charge cycles | Test the pack first, then decide on a swap |
| Phone switches off while the meter still shows charge | Tired cell cannot deliver a sudden load | Get it tested at a service centre |
| Back panel lifts or screen bulges | Gas inside a puffed cell | Unplug at once and visit a service centre today |
| Phone is warm while idle | Bad pack or a rogue app | Restart, take the cover off, ask a technician to test it |
Background apps and poor signal can also empty a phone quickly, so work through the battery health check before you buy a pack.
If the pack looks puffed, feels very hot or leaks, treat it as a fire hazard. Switch off, unplug, never press or prick it, rest the phone on a bare hard surface away from curtains and bedding, and get it to a service centre within the day. Counterfeit packs with inflated capacity labels are common, so accept only the exact code.
Fitting a replacement safely
The Oppo A53 and A32 are sealed phones, so let a trained technician open the back. Take the phone to an Oppo service point, or to a repair counter that has a good record. Hand over the model number and ask for BLP805 to be checked against the old label.
A poor copy usually shows up once it is on the bench:
- It weighs less than the pack you are replacing.
- The print is blurry and no batch or date marks appear.
- It promises far more than 5000 mAh, which a cell of this outline cannot honestly hold.
For a longer walkthrough of fitting, read mobile battery replacement.
After the swap, give the new pack one full charge and one full day of use before judging it. Its true run time shows only after a day or two.
Looking after a big mid-range pack
A large pack in a mid-range phone tends to sit on the charger through the night. Heat and long hours at 100 percent wear it faster. Charge on a hard, open surface instead of soft bedding, keep the handset shaded from strong sunlight, and remove a tight cover if the body runs warm.
Charge with the adapter supplied in the box, or any with an equal or lower watt rating, and throw away a cable that gets hot near the plug. How long the screen stays on per charge is set by the display, signal, brightness and apps, not by mAh alone. For the wider method, read the guide to finding any battery model name, and for quick drain see the causes of fast battery drain.
