So I've had my s8 a couple of months the now and I've changed to new Oreo version and downgraded to nougat because of the battery, even though now all of a sudden nougat is not performing as expected, I've used my phone mainly for 1:30 but still turning it off for a minute or two, the battery is already at %65 is this normal? I'm pretty sure battery is meant to last six ours in full usage of screen time, if anyone knows anything that might help would be grateful and I've tried everything I've heard about for saving battery and nothing of that has helped
