Some listings give the Realme 8 5G battery model name as BLP803, a 5000 mAh typical cell for model RMX3241. A few other listings call the same phone's pack BLP841, so the two sources do not fully agree. That is why you should treat the label on your own battery as the final word.
People also search this as "realme 8 5g battery model" or "realme 8 5g battery model number". Two different things are being asked there. The battery code starts with BLP and sits on the cell. The phone model number, RMX3241, is the one you see in Settings or on the box. You need both when you ask for a replacement.
Quick facts
Step by step
Find the phone model number first
Open Settings and go to About phone. If the model number is not shown, type model in the Settings search bar. A Realme 8 5G should show RMX3241.
Check the box or the retail sticker
The carton usually prints the phone name, memory version and model number. Take a photo of it, since it helps when you order.
Let a technician read the cell sticker
On this sealed phone the battery code is visible only after the back panel is lifted. Ask the technician to read the code aloud and tell you the capacity line too.
Compare the new pack with the old one
Put both packs side by side. The code, the capacity line, the connector shape and the size should all match before anything is fitted.
Realme 8 5G battery model name: BLP803 or BLP841
Two codes appear for this phone. One group of listings names BLP803 for the Realme 8 5G with model number RMX3241. Another listing gives BLP841 as a pack for both the Realme 8 4G (RMX3085) and the Realme 8 5G. Both give 5000 mAh.
| Code | Phone it is listed for | Status |
|---|---|---|
BLP803 | Realme 8 5G, RMX3241 | Listed, used on this page as the main answer |
BLP841 | Realme 8 4G, and also the 5G in one listing | Disputed for the 5G, so verify |
A phone maker can change a supplier part between batches, and a repair listing can also copy a wrong code from another listing. Because of this, do not order on the basis of a web page alone, including this one.
Where the code and model number can be seen
On the Realme 8 5G, three places each answer a different question. Settings and the box tell you the phone. Only the cell sticker tells you the battery.
- About phone in Settings: gives the Realme 8 5G name and RMX3241. It does not show the battery code.
- Retail box: prints the model number and the memory version.
- Battery sticker: carries the BLP code, the capacity and usually batch marks. It is behind the back panel.
The Realme 8 5G is sealed, so never lever the cover with a blade. A slip can cut the display cable or dent the cell. Our Oppo group code list covers every BLP code, and the label reading guide shows how to find one on any phone.
Photograph the old sticker with the flash off and the phone tilted slightly. Glare can hide the last character of a BLP code.
Capacity: what 5000 mAh means on this phone
Both listings give the Realme 8 5G 5000 mAh, the typical figure. BLP803 labels often print a rated minimum slightly lower. Your label will show the exact pair, so read it instead of assuming.
BLP803 watt hours are 5000 mAh times the voltage, divided by a thousand. BLP803's voltage is unconfirmed, so use your label. Purely as an example, 3.9 V would put BLP803 near 19.5 Wh.
How long the phone lasts in a day depends on the chip, the 5G signal, screen brightness and refresh rate, and the apps you keep open. The mAh figure is only one input. The Realme 8 5G's 18 W adapter and cable decide how fast BLP803 refills.
Signs the pack is wearing out
| Realme 8 5G sign | What causes it | BLP803 action |
|---|---|---|
| Charge drops quickly on 5G | Aged cell or weak signal area | Try the 8 5G on Wi-Fi, then check health |
| 8 5G turns off near 25 percent | Worn BLP803 cannot give peak current | Have BLP803 tested |
| 8 5G screen lifts from the frame | BLP803 has swollen | Unplug the Realme 8 5G, visit service today |
| 8 5G back very warm while idle | Worn BLP803 or a stuck app | Restart the 8 5G, remove the case, test BLP803 |
Before blaming BLP803, read our drain guide and run the health check on the Realme 8 5G.
Should BLP803 swell, overheat, leak or dent, it could ignite. Unplug the Realme 8 5G now, don't press or flex it, and move it from heat. Plenty of BLP803 fakes print far beyond 5000 mAh, so accept a spare only if the code matches your old cell.
Fitting a new pack and avoiding copies
This phone should be opened by the brand's service centre or by a technician you trust. Give the person your model number RMX3241 and the code from your old sticker. Ask for the code to be compared before the adhesive is touched.
- A good pack has crisp print, batch marks and a weight close to the old one.
- A pack that feels light, or claims a number well above 5000 mAh, is probably a copy.
- The connector should be the same shape and in the same spot.
More on this is in our swap guide. Ask to see the old BLP803 and photograph its sticker in case you need to come back.
Everyday care for a 5000 mAh pack
Heat does the most damage. Never charge the Realme 8 5G in a hot car or under a pillow, and remove a heavy cover during long calls or games. Holding BLP803 at 100 percent for hours wears it too.
Use the Realme 8 5G's boxed charger or a known brand rated the same or lower. Replace a cable whose plug end gets hot. If a reboot and full top up do not stop the Realme 8 5G quitting early, test BLP803 before buying anything.
