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.
So it seems that after years that samsung is in the top smartphones makers they are not able to make a decent firmware and a still powerful device HAS TO at least or battery drain or lag in the most simple tasks. Well done samsung, as always. I'm still wondering how they replied to the report I sent where I mentioned planned obsolescence but my members app still keeps force closing 😂
Battery seems to have improved a little bit with the latest update for me, also the cell standby thing is gone.
However battery life for me was satisfying before and still is after the update, so no problems there.
It is may be a good idea to watch the real batterylife instead of looking in the statistics. I wonder if they are so smart to just modify the statistics to calm down the users as Samsung allready stated that this is an issue of ststistics only.
Battery does last longer for me after the update, but since I'm away from home it could just be that the signal is slightly better. Still, if I reach 4 hours SOT, can't complain.
Just to be clear I also deactivated 4G calls (VOLTE) through my carrier's app (noticed a big improvement at the time), and disabled most of the bloatwares with a well known app.
How is everyone getting on with the new update? I've been running it since Friday. I am downgrading back to Nougat. For me battery life is worse and the occasional stutters are becoming annoying.
I'm running a stock-based ROM from xda called DevBase 5.8 Oreo and i flashed on top of it the latest bootloader, modem, and kernel and my battery life is better than on Nougat. It's really sad if xda developers are doing a better job than Samsung.
