BLPA41 battery model name: Oppo Reno 11F 5G battery

The phone behind the BLPA41 battery model name

The Reno 11F 5G is a mid-range Oppo phone sold in several Asian markets with a 5000 mAh battery and 67 W charging. Replacement sellers list BLPA41 as its direct replacement and give 3.91 V and 19.55 Wh, matching the 5000 mAh capacity.

BLPA41 battery model name and the Reno 11 family

The Reno 11 series includes the Reno 11, Reno 11 Pro and Reno 11F, with a separate pack for every model. The 11F is the most affordable of them, with a 5000 mAh pack and a flat AMOLED screen. The Reno 11 and 11 Pro have different internal layouts and should not be fitted with a BLPA41. If your phone's information page shows Reno 11F 5G, expect BLPA41 printed on its cell.

Where BLPA41 sits among A series codes

Confirming the code

Look for the CPH number of your Reno 11F in its device information page. Getting at the cell means lifting a bonded rear panel, best left to trained hands. The BLPA41 sticker shows 3.91 V, a higher charge limit voltage and the capacity lines.

Why 3.91 V matters

Recent Oppo cells sit at 3.91 V nominal, a notch above the 3.85 to 3.87 V of older ones. That raises the energy stored for the same mAh: 5000 mAh at 3.91 V is about 19.55 Wh. To compare a BLPA41 with any other pack fairly, convert both to watt hours first.

Getting it replaced

For a recent phone like the Reno 11F, battery problems in the first year are usually a warranty matter for Oppo service. Later, a genuine BLPA41 from Oppo is the safe route. The Oppo code list and our battery swap walkthrough help with the rest.

Battery life on the Reno 11F

In good health, a BLPA41 carries the Reno 11F from breakfast to bedtime, and its 67 W charging refills the pack in under an hour. Oppo's battery settings include an optimised charging mode that slows charging near full overnight, which helps the cell last longer. If the phone suddenly drains faster after a software update, give it a day for background tasks to finish before drawing conclusions.

For the arithmetic behind mAh and watt hours, the guide to mAh and Wh covers it.

Reading BLPA41 off the cell sticker

Oppo prints BLPA41 near the top of a genuine sticker, followed by 3.91 V, the upper charge voltage and a rated figure slightly below the advertised 5000. A QR code and production code are usual. If a replacement shows only "Reno 11F battery" and a capacity, without the code, treat it as generic and ask for a better part.
