Most listings tie the BLP835 battery model name to four Oppo phones: the F19 Pro, Reno5 F, Reno5 Lite and A94 4G. Sellers describe BLP835 as a Li-ion polymer cell near 4310 mAh typical. It comes from the Oppo group, and BLP is the prefix Oppo puts on most of its own cells.
Some type it "blp 835 battery model name", with a space. Spacing makes no difference to BLP835. What does matter is the phone: Oppo sold several F19 models, and they use different cells. Only the F19 Pro is matched here, so the F19s and the F19 Pro Plus need their own check.
Quick facts
Step by step
Write down the phone name and model number
Open Settings, tap About phone and note the name and the model number that starts with CPH. If you cannot find it, type model in the Settings search bar.
Have the old pack read, not guessed
After the back is opened by a technician, the word
BLP835should be on the cell label. Do not pull or bend the pack to see it.Hold the old and new packs together
The new one needs the same code, a similar thickness and the same connector end. Even a small gap in size means a wrong pack.
Judge the new pack before it goes in
Look for clean print, batch marks and a weight close to the old pack. A very light pack that claims a huge capacity is a fake.
Phones listed for the BLP835 battery model name
BLP835 is one of the Oppo packs that serve more than one phone. A parts listing for this code names the F19 Pro, Reno5 F, Reno5 Lite and A94 4G together, which fits a shared battery. Treat this as a listing match and not a maker statement.
| Oppo handset | Status | Note |
|---|---|---|
| Oppo F19 Pro | Matched by listing | Sold in India |
| Oppo Reno5 F | Matched by listing | Check the label first |
| Oppo Reno5 Lite | Matched by listing | Check the label first |
| Oppo A94 4G | Matched by listing | Check the label before you order |
| Oppo F19s | Not confirmed | Own code page |
| Oppo F19 Pro Plus 5G | Not confirmed | Read the old label |
The model number on your phone decides which of these you own. Oppo phones with similar names can hide different boards and packs, so the name alone will not do.
How many mAh is the BLP835 battery
The figure of 4310 mAh is the typical capacity, the number that adverts and spare part listings repeat. BLP835 labels usually print a rated floor slightly below 4310 mAh. No rated BLP835 value is confirmed, so read it from the cell in your F19 Pro rather than a seller's guess.
BLP835's energy is 4310 mAh times its label voltage, over 1000. BLP835 at 3.87 V gives about 16.7 Wh. BLP835's voltage is unconfirmed here, so use your own label for the sum.
A bigger number on a copy does not mean a longer day. Screen brightness, signal and apps change real battery life a lot, whatever the mAh figure says.
Confirm the code before you pay for a pack
Order only after you have seen the code with your own eyes or in a photo. The phone name is a hint, and the label is the proof. A mix-up costs a day of travel and a second repair visit.
- Have the technician photograph the old BLP835 label with code, batch and capacity visible.
- Check the CPH number in About phone against the Reno5 F or F19 Pro box.
- Check that the BLP835 plug and outline match the replacement.
A customer brought an F19 Pro with a battery that drained by afternoon. The counter had a pack for an F19s in stock, since the names looked alike. Once the Reno5 Lite was open, the technician read BLP835 and turned down the other pack. The correct code was sourced the next day.
BLP835 versus nearby Oppo codes and look-alike phones
Oppo codes run close together, and a one or two digit gap says nothing about the phone. BLP837 and BLP841 sit right next to this number, yet each has its own page and phones. Close digits never make two BLP codes interchangeable.
- The Oppo F19s battery page covers a different F19 model.
- The Oppo F19 Pro Plus 5G is not confirmed for BLP835, so match the label.
- Reno5 and Reno5 Pro, the ones without F or Lite in the name, are separate phones. Do not assume they use this pack.

When a BLP835 pack is wearing out
| F19 Pro sign | Usual cause | BLP835 action |
|---|---|---|
| Percentage drops quickly after charging | Cell has lost capacity over many cycles | Check how healthy the battery is, then plan a swap |
| F19 Pro cuts out with 20 percent showing | Weak cell cannot give peak current | Have Oppo service check BLP835 |
| Screen lifts from the frame | BLP835 swelling from below | Unplug the F19 Pro and go today |
| Back panel hot during idle | Faulty pack, charger or a stuck app | Restart the Reno5 F, remove its cover, then test |
Before blaming BLP835, see our drain explainer, since apps and weak signal cause most A94 4G complaints. If the problem stays, follow the health check steps.
Swelling, heat, leaking or dents make a BLP835 a fire hazard. Pull the plug on the Reno5 F, leave the swollen cell alone and move the phone somewhere cool. Cheap copies often carry a false capacity label, so accept a pack only if the code reads BLP835 exactly.
Fitting a BLP835 safely
The F19 Pro and its cousins are sealed phones with glued backs. Opening these Oppo phones needs heat, tools and practice, so leave it to Oppo service or a repair shop you trust. Quote the phone name and CPH number and ask them to compare BLP835 with the old cell.
Signs of a poor BLP835 copy:
- It is noticeably lighter than the BLP835 you removed.
- BLP835 lettering smudges and the batch marks are missing.
- It claims more than 4310 mAh in the same body.
More fitting advice is in our swap walkthrough.
Back up photos and contacts before the visit. A repair is routine, but a phone left for a few days should never hold the only copy of your data.
Everyday care for this pack
Most F19 Pro owners charge at night and keep the phone at full charge for hours. Long hours warm and full wear out BLP835 sooner than heavy use does. Never charge the F19 Pro beneath a pillow or in sunshine, and take off a chunky case once it warms.
The F19 Pro and Reno5 F charge at 30 W, so use the boxed set or one with the same rating. Change any cable whose plug heats up. If the A94 4G keeps quitting early after a reboot and full top up, a worn BLP835 is the likely cause, so get it measured.
