Please take note of the following:
•Always use the realme original power charger and USB cable that came along with the phone.
•Charge it at a normal ambient temperature.
•Try not to use your realme Phone when charging especially when it is a long call or when playing a game.
•There are no historical-usage impacts (memory impacts) on Lithium-Ion batteries, you can feel free to charge/drain it whenever your preferred time, and we don’t recommend charging the battery in a long-time (Ex: charging it over-night).
