The BLP731 battery model name belongs to the Realme 5 Pro, which is why searches for "realme 5 pro battery model name" lead here. Realme gave the 5 Pro a 4035 mAh battery, and original BLP731 listings match that; most replacement sellers print about 3900 mAh at 3.85 V, close to the rated figure.
The Realme Q, a China version of the same phone, is listed with BLP731 too. Its sibling, the plain Realme 5, packs a larger BLP729 pack.
Quick facts
Realme 5 Pro battery model name and its twin
| Phone | Model number |
|---|---|
| Realme 5 Pro | RMX1971 |
| Realme Q (China) | RMX1971 variant |
Our Realme 5 battery page explains why the non-Pro model takes BLP729.
4035, 3950 or 3900 mAh
Realme's specification is 4035 mAh. Original listings use that figure. Replacement sellers print 3900 mAh or, in one marketplace, 3950 to 4035 mAh. The lower figures are the rated value or a slightly smaller aftermarket cell. Anything well above 4035 mAh is not credible for this body.
Realme 5 Pro next to the Realme 3 Pro
The Realme 3 Pro, released a few months earlier, used BLP713 at about 4045 mAh (the plain Realme 3 has its own BLP693), very close to the 5 Pro's 4035 mAh. Because the capacities match, shops sometimes treat the packs as interchangeable. They are not: the outlines and connectors differ. Match BLP731 by code for a 5 Pro.
Confirming BLP731
The About phone screen should read Realme 5 Pro with RMX1971. The plastic back is held by adhesive, and the fingerprint sensor ribbon sits on it, so careful opening matters. The cell label shows BLP731, 3.85 V and the capacity lines.
A Realme 5 Pro has been through years of 20 W VOOC charging. A raised rear or warmth while idle means the BLP731 should come out before it pushes on the display.
BLP731 battery model name and VOOC charging
VOOC charging needs a cell and connector that the phone recognises. A poor BLP731 copy may still charge, but slowly, or may get hot. If VOOC stops working after a battery swap with the original charger and cable, the pack is the likely cause. More Realme codes are in the BLP family list, and our health check guide helps judge the old pack.
Keeping a Realme 5 Pro going
A new BLP731 gives back roughly a full day of moderate use. VOOC fills it from low in a little over an hour. Clean the USB C port if charging becomes unreliable; lint is a common cause on phones this age.
Is a Realme 5 Pro still worth a new battery
Four rear lenses and a mid-range processor keep the 5 Pro useful for everyday apps even now. For a second phone or for a family member who mainly calls, messages and watches videos, a new BLP731 is a sensible repair. If the phone also needs a screen or charging board, compare the total cost with a newer budget phone before deciding.
Where to get BLP731 in India
Realme service centres still list parts for the 5 Pro, though stock of older models can take a few days to arrive. Independent shops usually keep aftermarket BLP731 packs. If you choose one, ask whether it supports VOOC and test fast charging before you leave the shop: plug in the original adapter and check that the phone shows the VOOC charging indicator. A pack that only charges slowly is not the right part.
