some recently downloaded 3rd party app must be the reason for battery drain.. go to device care in settings and put the apps to sleep which you think dont need background usage.. like Gmail, Whatsapp, Instagram, Snapchat.. these apps need background running or else you wont recieve any notification.. so dont put these apps to sleep.. but Travel apps like MMT, Goibibo, etc does not need background usage so put such apps to sleep.. This will improve your device performance and Battery drain.. also check the screen resolution.. downgrade the screen resolution when you are not watching videos or playing games..
well for normal tasks like chatting, browsing, etc you cannot find out the difference between FHD+ and WQHD+.. its only when you watch videos or games you need WQHD+.. but turning on WQHD+ all the time eats up battery.. its just a trick to save battery.. you can keep it on all the time if you feel that you have spent 80k for that.. 😀
