Bro these are compromises...and M30s officially contains 6000mah battery, are you getting the meaning of 6000mah....when one will use so roughly (like Pubg whole day) even then it should not die before 10-12 hrs and interestingly I don't play pubg and still they are showing me 14:33 hrs, which will die before that even.
And fyi M series do not contain many specific battery draining features of Samsung.
I want them to improve, I am not asking for some tips of saving battery by compromising normal usual settings.
