For those getting Screen on time of more than 8 hours per charge, can you share your current settings to us?
Hopefully others can copy and get the intended battery life we paid for lol.
Although I'm not using your model of phone @konarenz battery saving tips are pretty much similar on most phone's.
There are existing threads on the forum that discuss some good one's. A forum search should bring them up.
Here are some of the one's I always use.
Just a little less than 50% screen brightness.
Adaptive brightness turned Off.
Some apps set to deep sleep and some set to sleep mode.
Some turn off the Adaptive 120hz screen refresh rate to a lower one. Mine is on adaptive 120hz.
Some don't use the highest screen resolution. Mine is on FHD+
I let my phone sync most things regularly but some curb how many items sync and how often.
Screen time out is set to 2 minutes.
Also remember I'm the early stages your phone is learning your usage.
Check in Device Care and Battery to see what's using your battery the most.
I turn off the battery % sign in my status bar so I'm not continuously drawn to it.
My phone easily lasts 2 to 3 days.
I have the Snapdragon soc version that in my opinion optimises better than the Exynos soc.
