Battery draining problem for s8

[Maheshreddy7]

Why is s8 draining battery heavily after the last update than before? Is it only for me or everyone else??

you should have taken battery life in consideration while buying. s8+ has more battery life than s8.

The backup was nice previously but it dropped down.This is the issue.
reg comment: If u say so , shouldn't we expect the max battery life on a flagship phone ( I'm just keeping an extra budget of 20k to enjoy the premium feautures.or else i could have opted for one plus phones!!!
