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.

Other SmartphonesHi all, I'm writing from Italy.
I own an S7 flat no brand. Like most of you I experienced battery drain after updating to Oreo.
Many people on the Italian Samsung community have been talking about flashing the CP (modem/radio) with a previous version but according to my extensive tests that will NOT fix the issue.
Yeah it will show the correct % value for standby cell, but it won't actually change anything in terms of battery life.
The problem is somewhere else.
Having this said, battery life was about 24 hours + 8 in airplane mode with Nougat = 32 hours, and 14 hours + 8 in airplane mode = 22 with Oreo with same usage, battery saving ON, most of apps frozen in background, etc.
Cheers

Other SmartphonesHi all. Just a quick word of caution that unofficial changes to your phone's software, may invalidate the 24 month Samsung Warranty on your phone.

Other SmartphonesI live in Lebanon where you only offer 1 year of warranty, sadly. Can you make it two years like the rest of the world?

Other SmartphonesXsever your question has 2 problems: 1 is off-topic. 2 wrong continent.

Other SmartphonesTo all. If you rely on Samsung in solving the battery drain, good luck! Contacting Samsung support is useless. They are incompetent Flashing the modem won't help. Downgrade to Nougat is the only solution. Enjoy!

Other SmartphonesWell noted. Thank you for the clarification.
I just love how blazing quick Samsung is in reminding people that using "unofficial changes to the phone's software" will void the warranty while they are painfully slow in fixing a battery drain problem on 2-year old flagship phones. Honestly, these unofficial changes by forums like xda and the likes have been much faster than multi-billion $ Samsung in resolving issues with the rom, kernel, bootloader, and modem that Samsung is supposed to be responsible for.

Other Smartphones@Tecnico to be fair... i did downgrade to Nougat and there is no drain. But if I'm honest... despite drain absence, SOT is still the same as before

Other SmartphonesHi,
thats intersting. If you have same sot as with oreo with the same amoumt of hours in stand by.this means that this cell stand by drain is only an error in the battery statistics ?
Really ??

Other SmartphonesYes Oliver, it's just wrong statistics, which actually makes things even more complicated as the cause of battery drain remains unknown.
