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.

Yep, weird that update released for G930 only, but not for both G930 AND G935. I really hope that this is the long waited fix for us.
I couldn't find it on sammobile

Other SmartphonesDownloading for G935 will flash tomorrow and give it a whirl. I do have EE EVR firmware on the phone but it doesn't show an update for some reason.

The problem discussed in this thread isn't manifesting at night, while connected to WiFi (w/ or w/o AOD). The issue is battery drain while connected to 4G.
So, when you have a week of experience with your experiment, while connected to 4G, please update your report.
Last night before going to bed, I made sure the phone is fully charged up, I unplugged it, turned OFF AOD and Wi-Fi and left it on LTE all night.
Results:
1.2%/h battery drain for a total of 5 hours. On Nougat, the best I've gotten is 2.0%/h.
Again, my phone is an S7 Flat running an xda oreo stock rom called DevBase 5.8. My modem is now ERG2 which got updated 2 days ago and I got the modem off of a Telegram channel and flashed it using twrp. So where is Samsung out of this entire equation? Xda and telegram have been more helpful.
I look forward to your response

Other SmartphonesInstalled EVR last night, thus far no sign of Cell Standby Drain and battery life seems pretty normal so far.
