Troubleshooting Steps:
1. Restore the earphone to factory settings and upgrade the earphone firmware to the latest version in realme Link.
2. It is recommended that you use the original data cable to connect the adapter (recommended to use a power adapter of 5V/2A and above) and try it after charging for more than 15 minutes.
3. According to the chemical characteristics of lithium batteries, in order to ensure the safe use of the earphone battery, the product cannot charge the earphone when the temperature is lower than 0°C or higher than 47°C. It is recommended that you charge the earphone at a temperature of 3°C~45°C.
4. It is recommended that you observe whether the charging contacts of the earphone, the charging shrapnel of the charging box or the probe are stained with oil/sweat or dirt. If so, try cleaning with a lint-free cloth or cotton swab.
5. You can try to touch the charging shrapnel with your hand or with a soft tool to see if there is any rebound. If there is no rebound, please go to the realme customer service center with the purchase certificate for testing and processing.
If you still cannot charge after following the above methods, it is recommended that you bring your purchase certificate to the realme customer service center for testing.
