The B-R5 battery model name, often typed as BR5, belongs to the vivo V23e in most replacement listings, with the 5G version sharing the same pack. vivo sold the V23e as a 4050 mAh phone; several listings print 3950 mAh, which fits the usual gap between the typical and rated figure.
The V23e is a slim phone, so its battery is smaller than the 5000 mAh packs common in budget vivo models. That is normal for this design and not a sign of a weak copy.
Quick facts
Phones that use the B-R5 battery model name
Spare part sellers list B-R5 for the vivo V23e and its 5G sibling. One retailer also names the S10e, a China model on the same design, which is why the code turns up on import sites. In India, the V23e and V23e 5G are the phones that matter.

4050 or 3950 mAh: which is right for B-R5
Both. vivo advertised 4050 mAh, the typical value. A pair of seller pages show 3950 mAh with 3.89 V, close to 15.4 Wh, which reads as the minimum floor every cell must reach. A third listing quotes 4050 mAh. If a seller offers a B-R5 at 4500 mAh or more, the label is inflated.
Our battery capacity guide explains why phones carry two figures.
Do not mix up B-R5 with nearby vivo codes
vivo codes differ by a single character. B-S1 and B-S2 are Y-series packs, B-P5 belongs to iQOO models, and B-O5 is the Y20 family battery. None of them fits the slim V23e body. The full list sits on the vivo battery model list.
Checking and replacing a V23e battery
Confirm the phone model under Settings, then About phone. The V23e is sealed with glue, so the back has to be heated and lifted by a technician. Ask them to show you the old B-R5 label before fitting the new cell, and check that the new one has a printed batch number.
A slim phone like the V23e shows swelling quickly as a raised back or a screen lifting at one edge. Stop charging at once and take it to a vivo service centre; do not press the bulge back down.
Signs the V23e battery is worn
- The phone needs a top up by mid afternoon with your normal routine.
- The percentage jumps, for example from 30 to 12 in a few minutes.
- It shuts down when the camera or a game starts.

Charging the V23e without wearing the pack
The V23e supports 44 W fast charging with vivo's adapter, so a slim 4050 mAh pack fills quickly. That speed comes with heat, and heat is what shortens the life of a thin cell. Charge on a desk, not on a bed, and pull off a tight cover if the phone feels warm in the hand. Overnight charging is fine if the phone is on a hard surface; many vivo phones also offer an option to stop at 80 percent, which you can look for by typing "battery" into the Settings search bar.
A B-R5 pack that has gone through two or three years of daily fast charging will often hold around four fifths of its first capacity. That is the point where most owners notice the phone no longer reaches the evening.
