The BLP819 battery model name appears on an Oppo pack that sellers list for the Reno6 4G (CPH2235), the Reno5 Z 5G and the F19 Pro+ 5G, with one seller adding the Reno5 4G and A95 5G. Listings agree on about 4200 mAh at 3.87 V, roughly 16.3 Wh, which is the rated value behind the 4310 mAh class these phones were advertised with.
Despite the BLP prefix shared with Realme, we found no Realme phone using BLP819.
Quick facts
Oppo phones matched to the BLP819 battery model name
| Phone | Support |
|---|---|
| Oppo Reno6 4G (CPH2235) | Several listings |
| Oppo Reno5 Z 5G | Several listings |
| Oppo F19 Pro+ 5G | Some listings |
| Oppo Reno5 4G, A95 5G | One seller |
The F19 Pro+ was the India model in this group; the Reno5 Z and Reno6 4G sold mostly elsewhere.
4000, 4200 or 4310 mAh
One Indian listing for an F19 Pro+ battery quotes 4000 mAh; most others quote 4200 mAh. Oppo advertised these phones at around 4310 mAh typical. The 4200 figure is a sensible rated value; 4000 suggests a weaker aftermarket pack. Choose the label that reads closest to 4200 mAh rated.
Confirming BLP819 on your phone
Each of these Oppo phones carries a CPH number that pins down the exact model. Opening these Reno and F series phones means warming a glass or plastic back, so it is a job for a service centre. The cell should read BLP819 with 3.87 V and a charge limit near 4.45 V.
Thin phones like the Reno6 show a swelling battery as a back that rises at one corner. Leave such a phone unplugged and let a technician deal with the cell.
Neighbouring Oppo codes
Oppo phones from the same period include BLP805 in the A53 and BLP841 in other models. Codes in the 800s are close together and easy to misread on a faded sticker. The Oppo, Realme and OnePlus index lists them all.
Battery life and fast charging
The F19 Pro+ and Reno6 4G support fast charging at 50 W and above with Oppo's adapter, so a 4200 mAh class pack fills in well under an hour. In daily use a healthy BLP819 covers a full day. If yours needs charging twice a day, check the battery menu for a misbehaving app before blaming the cell.
Replacing BLP819
Oppo service centres can supply the part for the F19 Pro+ in India. For imported Reno models, ask the repairer to source a pack that names your CPH number. Retain the original pack until the fresh BLP819 completes one full cycle.
BLP819 battery model name and the F19 series
Oppo's F19 series in India had several members: the F19, F19 Pro, F19 Pro+ and F19s. Only the F19 Pro+ 5G appears in BLP819 listings. The others used different batteries, and the Oppo F19 battery page covers the plain F19 and F19s. If you are unsure which F19 you have, the name on the About phone screen will include Pro+ for the BLP819 model.
Because the Reno5 Z and Reno6 4G sold mostly outside India, genuine BLP819 stock in India mainly comes through the F19 Pro+ service channel. An Oppo service centre can order it by model number.
