Hi,
I really like my S7 Edge. However as a direct result of installing the Oreo update I have significant battery drain. The drain is attributable to cell standby which sometimes reaches over 50% of battery use. It definitely did not do this on Nougat, ever.
I have not added any apps to cause this problem and would really like a suggestion about what to do. I can't believe Safe Mode will have any effect as this has happened as a result of the upgrade, not rogue apps. I am not keen to do a factory reset either as I can't see the benefit. I have cleared the cache, removed some apps, restarted etc, turned off any battery hungry options in settings but to no avail.
If anybody could help me I would be very grateful. I believe it is a bug in Oreo or Samsung's altered version of Oreo but cannot prove either. I can't think what to do apart from find out how to downgrade back to Nougat, which I don't want to do.
Many thanks.

It looks very good. My phone has just become a brick after recording some video yesterday and crashing catastropically. If I can resurrect it this is what I will use instead of the stock rubbish.

I cant fault this Rom at all

I own a Motorola phone and have the exact same problem. Battery doesn't last through the day and cell standby uses from 8 to 50%. Runs on Android 7.0.

That's it. My S7 edge motherboard failed after 2.5 years. Maybe because it was heating up too much because of the incompetent software on Oreo written by Samsung. That's the nail in the coffin as far as I am concerned. I'll stick to washing machines from them but I ain't goin' nowhere near their phones ever again. They've had a bad press recently regarding battery life and I believe it fully justified especially after hearing about the S9 problems.
I've just bought a Nokia 7.1 running Android Pie and saved a stack of cash. It's brilliant. I know who I'd trust in future. In my opinion Samsung thinks exclusively about their pockets and for me that's just not good enough.
Sorry Samsung but you've cost me a lot of time and a lot of problems and you're arrogant. Now you've lost a once loyal customer.
