It's been 2 years I am using the s8 but I am utterly disappointed with the kind of battery stats I am getting.I have not got more than 3.5 hrs of SOT in my 2yrs of usage,Samsung should optimize the battery usage like the oneplus,apple,vivo etc
but atleast it should last for a typical working day on mobile data.I also own an iphone se as a secondary driver it gives me amazing battery stats at the end of the day it shows 30% of battery life with heavy usage
