My Samsung galaxy note 20ultra before battery won't last a day even with minimal usage ..now it lasting atleast 11hrs even with usage wow I have no idea wat was draining my battery before .. today I last charged at 6am ..its now 12:43 and its at 71...
Problem for super fast charging can be either the charger your using, settings u need to turn on super charging mode.. For the volume button you need to visit service center
