S8 exynyos mobile lasting more than one day under medium to heavy usage on oreo is now halved to just 11 hours. Phone was at 100 % charge at 8 am. It switched off at 7 PM due to low battery. Samsung please do something. I can't go ahead like this with a power bank in my pocket. I upgraded from oreo to one ui yesterday at 1 am in the night, but now I regret it. Other users of s8 beware. My phone no is +917592948463
