I bought this phone(Exynos Version) a week ago. But battery life is not upto par as it has 4000 mah battery. Is it due to the october update or something else? I am getting around avg of 4.5 hours of SOT. Anybody else facing this issue?

See, ideally it should give you 1.5 day of battery life with moderate usage. Heavy usage should last 1.2 days.

Try resetting your device to factory settings and then keep the battery optimized.

Activate the MID Option under

Settings -> Device Maintenance-> Battery as it puts to sleep most background battery apps.

If this doesn't improve the battery lasting time, share the report with us here and we'll try to find another fix.

Try draining out the battery completely to 0 and charging it fully to 100%. This will recalibrate your battery
