To fix the slow charging issue kindly follow the below-mentioned steps:
1. Use realme original charging cable and USB adapter.
2. Check your charging cable and USB adapter for signs of damage and make sure firm connections. Use another charging cable and USB adapter and try again.
3. Check the charging temperature. Charging at temperatures above 45 ° C will degrade battery performance, resulting in slower charging and thus longer charging times.
4. Close background apps and avoid using your phone while charging.
We hope this will help you. Further, if the issue persists kindly let us know.
