A search for BLP741 battery model name ends at the Realme X2, which most listings match to this code. Sellers list BLP741 as a polymer cell of 4000 mAh typical, rated around 3.85 to 3.87 V. BLP741 is an Oppo group part, the family that also covers Realme, marked by the BLP prefix.
People type BLP741 many ways, such as "blp 741" or "realme x2 battery model". The phone has a sealed body, so the sticker with the code is hidden until a technician opens the back. Some lists also add the Realme XT and newer phones to this code. Be wary of those lists and trust only the label on your old X2 cell.
Quick facts
Step by step
Write down the phone name and model number
Open Settings and go to About phone (some versions say About device). If you cannot find the model number, type model in the Settings search bar.
Match the model number to the Realme X2
Listings tie
RMX1991,RMX1992andRMX1993to the Realme X2. A number outside these is a reason to pause and check.Have the old sticker read when the back is open
Ask the technician to show you that label before the old pack is thrown away. It should show
BLP741together with capacity and voltage.Hold both packs together
The new pack should have the same shape, the same connector and a similar weight. Do not accept it if the connector end looks different.
Phones that carry the BLP741 battery model name
BLP marks an Oppo group cell, a group that includes Realme and OnePlus. BLP says nothing about the X2 itself, so the phone list matters more than the prefix. For BLP741, most listings point to one phone, and the model numbers below come from those listings.
| Phone | Model numbers in listings | Note |
|---|---|---|
| Realme X2 | RMX1991, RMX1992, RMX1993 | Listed at 4000 mAh typical |
| Realme XT | RMX1921 | Some lists add it; not confirmed, read the label |
| Realme X2 Pro | Not listed here | A different phone; code not confirmed as BLP741 |
| Newer Realme and Oppo phones | Appear in some bulk lists | Not trusted; read the label first |
Phones with the same body thickness and connector sometimes share one pack, which is why some lists add the Realme XT. Even so, a shared code is only a hint, so an old label settles the matter.
Realme X2 versus X2 Pro: a common wrong order
Searches for "realme x2 battery model name" often land on a pack for a different phone. The Realme X2 and the Realme X2 Pro sound close, but they are separate phones with separate battery listings. The word Pro is the clue. A pack bought for the Pro is not a safe guess for the plain X2, even if both show a 4000 mAh figure.
Check the box or the model line in About phone. If the number is one of the X2 numbers in the table above, the BLP741 listing applies. If your phone is not an X2, read the code on the old label instead of going by name.
A customer brought a Realme X2 and asked for "the Pro battery", since an online list showed both phones together. The technician checked the model number first, then read the old sticker after opening the back. It showed BLP741, so the plain X2 pack was ordered. Had the sticker read something else, the order would have been stopped.
Rated and typical figures for this pack
Most BLP741 listings show 4000 mAh, the typical figure in Realme X2 adverts. A few show 3900 mAh at 3.85 V, which looks like the lower rated figure. BLP741's watt hours are its mAh times its volts, then divided by a thousand. So 4000 mAh at 3.87 V is about 15.5 Wh, while 3900 mAh at 3.85 V is about 15.0 Wh.
The two numbers do not mean two different packs. They describe one pack in two ways. Your BLP741 sticker may print the rated value, so a slightly lower figure is normal, not a sign of a fake. The real red flag is a BLP741 claiming far beyond 4000 mAh at the same size.
On the X2, the AMOLED display, reception, brightness and apps set screen time more than mAh does. An older phone with a fresh pack will last longer than before, yet it will not match a newer phone with a more efficient chip.
Codes and phones to keep apart from BLP741
Codes in this family differ by a digit or two, and faint print makes 7, 1 and 4 hard to separate. Packs such as BLP731 and BLP737 look very close on paper, yet each is written up on its own page with its own phones. Do not swap them because the first letters match.
- A Realme phone from the same period may share the pack size, but not the code or the connector.
- The Realme 7 Pro is another handset with its own battery details.
- Before reading BLP741's last digits, angle the sticker under bright light or request a crisp photo.

What a tired BLP741 pack looks like
| X2 symptom | Likely reason | Next step for BLP741 |
|---|---|---|
| X2 percentage drops in jumps | Aged cell with weak capacity | Test X2 health, then plan a BLP741 |
| X2 dies with 15 to 30 percent showing | Cell cannot give peak current | Have Realme service test the BLP741 |
| Screen or back panel lifts | Swollen cell | Unplug the X2 and visit service today |
| X2 warm while sitting idle | Background apps or a tired BLP741 | Restart the X2, remove its cover, get BLP741 checked |
On the X2, check apps and reception first using our drain checklist, then think about BLP741. Then run the steps in the health check guide to see whether the cell is really worn.
Puffing, heat, leaks or dents turn BLP741 into a fire risk. Unplug the X2 right away, keep pressure off the cell and let it cool. Bring it to Realme authorised service. Copies of this pack with an inflated capacity label are common, so take a pack only when BLP741 is printed on it in full.
Getting the pack changed without trouble
The phone has a glued back, so opening it needs heat, tools and patience. Leave the X2 to Realme authorised service or a well regarded shop. Give them the Realme X2 RMX number and ask them to read the removed BLP741 sticker before fitting the new cell.
Three signs help you judge a BLP741 in your hand:
- It is lighter than the old BLP741.
- BLP741 lettering smudges and has no batch line.
- It claims 4500 mAh or more, which an X2 sized pack cannot honestly deliver.
See our battery replacement walkthrough for general advice.
Ask to see the new BLP741 label face up before the X2's back is closed. A quick photo of both labels avoids an argument later.
Looking after an older X2 pack
The X2 is several years old now, so its BLP741 has probably seen hundreds of cycles. Heat is BLP741's worst enemy. Avoid charging in the sun, under a pillow or while gaming with a thick cover on. If the phone runs hot on the charger, take the cover off.
Use the X2's 30 W VOOC charger and cable, or a good one rated the same or lower, and replace a cable that heats near the plug. Holding the X2 at full charge for hours slowly wears BLP741, so unplug when you can. When a reboot and full top up leave the X2 still dying early, BLP741 has probably worn out.
