Dont use back case and mobile data. Use wifi and don't use phone while charging. Put charger only when battery goes to 10-15%, do not charge in intervals. Use original charger and cable.
And still you want case for safety then use Spigen only if available in India.
In case the issue still occurs. Please register your concern in Samsung Members Application (Open Samsung Members Application > Support> Tap on error report > Type your query > Send).
