Yes I am also facing battery problem, but in a wiered way. Like my CELL STANDBY takes a lot of battery though I have very good cell network, and even when I am not using my phone that much.
My Exynos version dual sim S8 drains too much battery on CELL STANDBY. Tried network reset, clear cache partitiin, reboot. Works for only 2-3 days but after that same draining issue. Any solid solution? And what's the reason for this battery draining...
