hi i am facing battery drain issue in iqoo neo 9 pro which i bought 2 days ago 

it is draining from night to morning,I even turned OFF (mobile data ,location and wifi ) and cleaned the junk files still its draining.when i see in Battery>battery usage its showing usage of mobile data and by that some apps are running like snapchat(background restricted),whatsapp etc... 

i even tried airplane mode also there is no use
