Parts sellers mostly link the BLPA79 battery model name to the Oppo F27 and Reno12 F. Sellers put BLPA79 at about 5000 mAh typical. Oppo, Realme and OnePlus phones all use BLP codes, so the letters alone do not name your phone. The full code does.
People often type this code as "blpa79 battery model" or simply "f27 battery". Searches for either phone lead to BLPA79, provided your handset really is an F27 or Reno12 F. The Oppo F27 Pro+ and the Reno12 F 4G are different versions, and nothing here confirms that they share this battery. Check the code on your F27 or Reno12 F cell before ordering.
Quick facts
Step by step
Write down the phone name and model number
Open Settings, tap About phone and note the device name and model number. If you cannot find it, type model in the Settings search bar.
Separate the F27 from the F27 Pro+
Look at the retail box or the name under About phone. The Pro+ or 4G in the name means a different version, so do not order on the F27 name alone.
Let the technician read the cell label
Once the back is opened, the label should show
BLPA79along with capacity and voltage. Do not peel the pack or pull it out yourself.Compare old and new packs side by side
Check the code letter by letter, the connector shape, the size and the weight. Fit the pack only when all four agree.
Phones that use the BLPA79 battery model name
BLPA79 starts with BLP, the prefix seen on Oppo, Realme and OnePlus packs. The letter A after BLP is part of the name, so BLPA79 and BLP79 are not the same thing. Only two phones appear in BLPA79 listings, so use them as a lead and confirm on the label inside your F27.
| Oppo model | Status | Note |
|---|---|---|
| Oppo F27 | Named in most listings | About 5000 mAh typical |
| Oppo Reno12 F | Named in most listings | Check the BLPA79 print on the old cell |
| Oppo Reno12 F 4G | Not confirmed | Separate version, verify its code before ordering |
| Oppo F27 Pro+ | Not confirmed | Separate phone, verify its code before ordering |
For the wider family of BLP packs, go through the Oppo battery model list, where each code has its own page.
How many mAh is the BLPA79 pack
Expect around 5000 mAh for BLPA79, the typical figure Oppo puts in F27 and Reno12 F adverts. The label usually adds a rated minimum just below that. Whatever your own pack says is the number to trust, because batches differ.
BLPA79's watt hours equal 5000 mAh times its printed voltage, divided by a thousand. The voltage is printed on the label too. As a made-up example, a 5000 mAh pack marked 3.9 V holds roughly 19.5 Wh. Use the real voltage from your label, not this example.
Two packs with equal mAh are not always equal in energy or in size. Compare the code, then the capacity, never the capacity alone.
Confirm the BLPA79 code before you pay
The cheapest mistake to avoid is the wrong pack. Follow these checks in order:
- Match the exact phone name, including words like Pro+, 4G or 5G.
- Match the full code,
BLPA79, character by character. - Match the connector and the pack size against the old one.
- Check that the new capacity is close to the original, not far above it.
A customer brought an F27 Pro+ and asked for the F27 battery because the names looked close. Before ordering, the technician opened the Reno12 F and read the old cell's label. Reading the label first is what saves the wrong purchase.
Photograph the BLPA79 label in good light so the digits stay readable. If the letters look faint, ask the shop to read it again, because A, 4 and 6 are easy to confuse in small print.
Look-alike Oppo group codes to keep apart
The BLPA series has many members with only one or two characters of difference. A few near neighbours are BLPA77, BLPA83 and BLPA69. Neighbouring BLPA codes fit their own phones, so a close number does not mean a close phone.
- The last two digits decide the pack. A pack with 77 or 83 at the end is not a substitute.
- Reno series phones of nearby size may look like the Reno12 F but use another code.
- An older F series phone with a similar name is a different phone with a different cell.
When a seller offers a pack that has the right capacity but a different code, treat it as a no until the connector and size are proven to match.
Warning signs of a tired battery
| F27 symptom | Likely cause | Next move |
|---|---|---|
| F27 drains within a few hours | BLPA79 worn, fewer cycles left | Test F27 battery health, then plan a BLPA79 |
| Phone switches off at 15 to 30 percent | BLPA79 cannot give peak current | Get the Reno12 F cell tested by Oppo service |
| Screen lifts or back panel gaps appear | Swollen pack | Stop charging, go the same day |
| Reno12 F warm while idle | Worn BLPA79 or a runaway app | Restart the F27, remove its case, get it checked |
Apps and weak signal explain most F27 drain, so read our drain troubleshooting before running the health check.
A BLPA79 that swells, overheats, leaks or dents can catch fire. Pull the plug from the F27, leave the BLPA79 untouched and let the phone cool down. Take it to a service centre. Fake BLPA79 packs with inflated labels circulate widely, so accept only the exact code.
Getting the pack changed safely
Adhesive seals both the F27 and the Reno12 F, so a technician should lift the back. Give them the F27 or Reno12 F model number and have the old BLPA79 label compared with the new pack before the back is closed. Fitting advice that applies to any handset is collected under mobile battery replacement.
A weak copy usually gives itself away:
- It is lighter than the BLPA79 that came out.
- Lettering on the BLPA79 looks blurred and the batch line is absent.
- The label claims far beyond 5000 mAh, too much for a pack shaped for the F27.
Once the new BLPA79 is in, charge the F27 to full and then use it as usual.
Daily care for an F27 or Reno12 F battery
Warmth wears a BLPA79 more than charge cycles do. Keep the Reno12 F off beds and out of the sun while charging, and remove a thick case if it heats. Gaming while plugged in raises heat the most.
Use the F27's boxed 45 W charger or a reputable one rated the same, and replace a cable whose plug warms. F27 charge time depends on the adapter and on the phone's temperature, so slower charging on a hot day is expected. Unplug the F27 near full rather than leaving it at 100 percent for hours.
Frequently asked questions
Which phone uses the BLPA79 battery?
Most spare part listings match BLPA79 to the Oppo F27 and the Oppo Reno12 F. The capacity is about 5000 mAh typical. Read the BLPA79 print on the old cell to be sure.
Is BLPA79 the Oppo F27 battery model?
According to the listings seen, yes. With the F27 back off, the code is readable on the cell.
How many mAh is the BLPA79 battery?
It is listed at about 5000 mAh typical. The rated minimum on your own label may be a little lower.
Is the F27 Pro+ battery the same as the F27's?
Do not assume it. It is a separate phone and its code is not confirmed here. Check the label or the service centre record for your model.
Can I use BLPA77 or BLPA83 instead of BLPA79?
No, not unless the exact phone list says so. Close codes can differ in size and plug, so match BLPA79 in full.
Can I fit a BLPA79 at home?
Better not to. The Reno12 F is sealed, so Oppo service or a reliable repairer should do the work.
