Is it just me or battery backup is drastically reduced in oreo (December 1 security patch) update?
I'm having the same issue, 5% drop each 10 minutes or so of stand by
Can anyone give a configuration for any kernel or anything for this problem? Pls

Latest ota update, anyone updated?
NO. didn't get it yet. when we getting Android 7.1.1 Nougat update ?
Mine stuck at September security patch. But there is no reason to update because of the bootloader locked up. So no downgrade to early firmware build. So let's be root!
Off topic - I've buy G735F and the battery gave me 1.5 hour more sot. Of course smaller display size and similar performance. The real upgrade is the waterproofing. No reason for me to keep it up. Sd slot isn't usable for me.
We finally received the nougat update for S7 Edge in Denmark (this means Exynos version, SM-G935F). But should I upgrade or not? I like my current version, I heard battery time is worse on nougat and so on?
Also, would it be possible for me to try nougat out and then downgrade to marshmallow if needed?
downgrade should be possible but only with custom ROM i guess Battery was good at start 7-8 hours but now I'am back to 5-6 h sot with my normal usage, and started to get some google play stops... Will try to do a factory reset because I see a lot of junk from MM like people edge, that should be removed with Nougat?
You can flash any stock rom with Odin and thus you can downgrade to Marshmallow if you like.
The battery usage is much improved in Nougat.
I was running Nougat but after the horrible battery drain I decided to go back to Marshmallow, however obviously I want to keep ontop of the security updates provided by Google
Is there anyway to update these without having to update from Marshmallow

No, there is no way to apply security updates without updating to N. N is not causing your battery drain. Check your battery's capacity with a tool like Accubattery.
Hi, as the title said, is there any beginner guide for downgrading to Marshmallow? My S7 Edge is SM-G935FD, Exynos version. I've decided to downgrade it from Nougat because my battery life is horrible after I updated to the latest update. I read several threads that said they encountered problem with the vibrate motor. I don't want that to happen, obviously. Is there any solution to prevent that from happening? Thank you so much.

You can find a marshmallow rom and install it with odin but in my opinion its better to stay with nougat because the security patches and the battery will be better after some charge cycles

Actually it's been months and the battery is still horrible, so, no. And I don't plan on rooting anytime soon because my warranty is still 4-5 months left. But thanks for replying. Do you have other solution?
Hello,
1.Can we downgrade to 7.0 from 8.1? If yes,how?
2.Problems which may arise during downgrade?
3.If no why?
I'am fedup with the performance of 8.1,bootloops sometimes, network problems,and majorly battery backup and low volume issue.
#TIA

Did you installed the twrp version of an Oreo rom or which rom do you have. Did you have an unlocked bootloader? How did you update to oreo?
Upgraded to 8.1 (stock)through adb,i have bootloader unlocked and also have twrp.(no custom rom installed)

You cannot downgrade the bootloader if you flash the stock nougat rom by fastboot, otherwise it's hard bricked.
But I don't know if stock nougat rom will work with stock oreo bootloader @echo92, you know it maybe?

If stock Oreo is downgraded to Nougat, the bootloader may work with either firmware, I don't know for certain. However, OTA updates must be avoided if there's been a downgrade to Nougat or earlier (unless you're using the Oreo OTA); attempts to use old OTA updates on downgraded firmware is a great way to hard brick (and currently without recourse - we do not currently have a working Oreo blankflash).
However, if you downgrade your firmware, I am concerned you may lose SIM access/IMEI, given your baseband is on .77R (Oreo), whereas downgrading to Nougat would result in a baseband of .62.02R due to changes between the 2 basebands. You may have to consult this thread if you do lose your SIM/IMEI https://forum.xda-developers.com/moto-g4-plus/how-to/guide-moto-g4-plus-imei0-issue-t3859068
@anhoxhrs Have you considered replacing your battery, or at least ruled out battery issues like a failing battery? I'm just wondering if the bootloops and poor battery life may be due to the battery. Also, when you updated to Oreo, did you clean flash or factory reset your device?
The SOT has reduced by 30%,and most of the battery is consumed by mobile standby(weird).Its a clean flash. being my primary phone, 8.1 is troublesome.Yeah the battery was pretty good before the update.Chargeing time also has increased.for eg- 95 to 100 about 1/2 hr to 45 mins.
