bettery issue in s8

[milan4904]

after update to oreo i am facing a big bettery issue. bettery discharge very fast. i don't have any extra applications. no bluetooth no mobile data. and also phone is using in 2g mode. if i want to use phone for 12 hours i need to put it in power saving mode then only i can use it for 12 hours. even i see bettery usage it shows less usage then actual. like my bettery discharge by 45% but usage shows only 30% so it means even phone doesn't know where 15% of bettery power gone

format it, remove unnecessary apps , use battery management setting in settings option, optimize battery performance
