Maybe there was something left over that was causing you an issue. My battery on Oreo is fine. I really don't see it as better or worse than Nougat. I am lucky that no FR was necessary. I actually flashed twice - using Odin. First the stable "leak" that was floating around, and then again to get on to the proper official VZW build once that became available. Saw no difference between the two - with both running very smooth.My battery life tanked after oreo update. But after FR two days back, it seems to be as good if not better than Nougat. Also, no more McAfee notification when you do device maintenance and can optimize to 100% instead on 90%. I will keep posted on this.
Mine was like that right after the Oreo update but it's pretty much back to normal now, and all I did was clear cache a few times!I was getting an easy six hours SOT on Nougat, sometimes pushing seven hours. Now under Oreo, I'm getting five hours SOT, sometimes pushing hard to get six hours. Partition cache cleared before and after update, running clean phone no social media. Battery's SOT still good, but definitely lost approximately 10-15% due to update. We'll continue to see how things go with battery.
Also notification badges weren't working for Samsung mail client which fixed after FR. I don't remember adding app pair to home screen option before FR and I do see it now. Do you guys have it?
I feel the same about the battery, it's the same as Nougat.Maybe there was something left over that was causing you an issue. My battery on Oreo is fine.

Damn 4 resets wowit took four factory resets and now the battery finally doesn't stuck and everything works now. battery is better than it ever had been.
The most accurate way to see what is causing the issue is to install one app at a time and wait a while between each... When the problem has come back - then you know the last change caused the issueit took four factory resets and now the battery finally doesn't stuck and everything works now. battery is better than it ever had been.
