Hi,

My Samsung S8 since last upgrade to Oreo was a complete disaster. Just to be clear battery life during Android Nougat was good and it was the first thing ive noticed that samsung completely stepped up their game since their battery disaster on their certain phone model. Battery life would run at least from a day to 2 before recharging. Ive noticed there are other threads similar to these so i knew im not the only one affected, my colleagues also experience similar issues since upgrading to oreo so this is not something isolated to my s8 phone.

Few key points that ive noticed since upgrading to oreo:
1. Going to settings then battery usage. Screen would be the foremost battery hog at 26%, followed by Android System at 13%, then Device Idle at 9-8%. Cell Standby and Android OS remains normal.
2. Go to Settings then App. Ive noticed by checking each one of the apps that beaming services, device maintenance, settings, gear vr services were among the ones that took up most of the battery usage this is excluding system apps like AASAservice, etc.
3. Go to settings then data usage. The Android OS is sending or receiving 100MB of data (still counting). I wanted to know what are these data that is worth 100MB.
4. Device easily gets hot even light use of facebook, ig or 7 minutes of youtube video.
5. It sometimes restart, this is rare but ive noticed it since fingerprint cannot be used initially when there's a restart.

Now what ive done so far:
1. Cleared partition cache by holding bixby btn, volume up and power.
2. Disabling unused apps, even certain bixby services, etc.
3. Went to developer option and disable always on mobile data.
4. Factory reset device hoping it would go back to nougat but it did not. With a mint condition reset, it still drain too much battery. (without any third part apps or data restore)
5. Called up samsung customer service but was told to go to service center. Went to service center they check the ASOC of battery (which i think is unrelated) and according to them reprogram oreo. which did not help. wasted my time.

Now what is the implication?
1. I need to charge my phone at LEAST twice a day.
2. It heats up the phone which would definitely have negative impact on the longevity of this device one way or another.
3. It drains too much battery, with the amount of charge discharge multiplied at least by 2, this will literally messed up the battery life in the long run.
4. Im currently using 2 phones and my samsung s5 which is a 4 year old phone had better battery life. lol. Since in just 3 hours it consume almost 40% of battery.

There are tons of related post like these on different forums and on reddit but i surmise i should dig more on this problem before writing a more concrete post. At this point, i can only see 2 remaining options: 1. There is a step online that would revert the OS back to nougat but this would involved third party apps like odin, there are risk involved like phone brick, etc. Im not sure if it will void the warranty. OR i can just wait for a patch from samsung.

Now SAMSUNG NEED TO FIX THIS ASAP or provide us a way to revert back to nougat. With the s9 just available at the market, this terrible oreo release could not come at better time. I know there are several issues like the battery issues with their previous note model and Apples intentionally slowing down their phone, Samsung got to fix this fast before this issue becomes a blowout and many people will start to notice.

Man, i´m totaly on same boat!
In CRC7, i'm experiencing terrible battery life. Max 2.00 to 2.30 Screen on time in one charge. Now, for the first time, i have to recharge my phone befoure dinner.
Wifi , Bluetooth, Aod On, location history Off.

It´s the worst experience on any phone that i had in the past.
Like you, already disabled some apps, clear cache and already done a fresh install. Nothing works, nothing improved my battery.
I´m thinking send it to warranty, but it´s probaly not worth the time...

Maybe it´s time to forget about Samsung phone and move on. P20, or even iPhone X...

After updating to OREO and updating all galaxy apps, "beaming service" was draining my battery (67% of the battery actually). After uninstalling the updates on beaming service, the phone seems fine now. Maybe uninstalling the updates of which apps are draining the battery could help you guys as well.

ive tried that before but after fresh install. beaming service could no longer be disabled, nor its updates uninstalled.

Besides other apps are also draining battery like AASAservice, settings, device maintenance, etc.

You're right, that can't be disabled but I was simply able to uninstall the updates by clicking three dots top-right corner of app info screen. I've the latest version CRC7 on the phone by the way.

Hello !
I've been s8 for three months and I've never had any particular problems, I've upgraded to CRC7 (second update of Oreo) and I've already got twice the phone with a flat battery:
last week in the morning I found it at 1% from 35% the night before (during the night only the gsm network was active, everything else off); when in doubt I did a factory data reset by installing only minimal applications (FB, whatsup and little else) and I installed the Accubattery application to monitor the battery.
Last night put away (active gsm only) at 65% of residual charge and this morning after 10 hours it was 5%: 60% of charge consumed in one night.
Android does not report any abnormal consumption of any application .... it seems an anomalous battery drain
I enclose battery data screenshots; is not that the new Oreo update is buggy? or could the battery or the phone power circuit or the radio part that consume excessively might have a problem? Before bringing it to service I wanted your opinion and in case I wanted to try to put back the CRB7 version of Oreo .... how do I do it? do I lose the guarantee in this case?

I have the exact same problem as you and many others. I have tried various things to solve it and I concluded on that the modem firmware has a serious bug . airplane mode consumes more battery than on cellular. To make sure we are talking about the same thing please try removing your SIM card and let it all night . By the morning you have to be -2% of the battery . With the SIM inside now you have to drain 15-20% . If thats the case for you , you make sure that its not a faulty device and there is no drain from your setup (like an application draining etc .. in this case factory reset should fix it).
Cinfirm your findings and lets hope they will release update soon.

he doesn't do it every night, but random : in a week it happened twice
It's not in airplane mode, modem is switched on only for phone line (LTE off) ; I already tried two factory reset
Yours is affected only in airplane mode ?
Tonight , my s8 have to drain 60 % in 9 hours !

It drains in general but while in cellular it's difficult to distinguish if it's a bug or bad signal . Each ones phone may consume different amounts of energy depending on coverage etc. But in airplane mode you can be sure it's a bug because antenna transmission should be off and therefore not consuming energy . Just try as I said just to be sure we have the same issue . One night with airplane mode and SIM card in and another night airplane without SIM. You should see great difference .

Tonight ( gsm on ) have no drain : 0,3 % / h. ( 3 % in 10 hours ).
if it is faulty the battery should always do it?
Did you try to see if it drains, leaving the radio part active?

This will not help determine the bug because as I told you it's signal dependant. It's 3% in 10 hours because you probably had good signal . Else it could be more and even if you contact a service they will say it's not a bug but the signal . Anyway if you were with data on and 4g seems more than fine to me . Now if you try this night airplane mode for 10 hours it could drop 15-20% ... is this reasonable ?

in airplane mode is a bug, but a 60% night-time consumption with active gsm?
0.3% / h. the device was in the same position the night before when it consumed 60% in 9 hours

Your case seems more like a random application wakelock . Did you do a reboot between the 2 nights?
To distinguish better the cause of the drain , when you see an abnormal consumption try removing your SIM card for a while . If this fix the drain it's the buggy modem/radio firmware ...

    Well,
    After all I'm a lucky guy, because my battery life is great on my G950FD.
    I can get an average of 30Hours of working battery!
    Please check some details bellow:

    NO ROOT
    AOD = Off

    INFO SW:
    OREO 8.0.0
    samsung experience = 9.0
    baseband = G950FXXU1CRC7
    compilation= R16NW.G950FXXU1CRC7
    SW service provider = SAOMC_SM-G950F_OXM_BRI_OO_0021
    ce0571715ea6234ec0d
    BRI/BRI/BRI

    security patch = 1 of march 2018

    I can't say it's perfect . It's near perfect. From 30 hours standby you got only 2:50 SOT . Your battery curve should be somewhat horizontal (especially with aod off) when on standby but it keeps dropping even without using it . With nougat and this usage I would have 30-35% battery left
    1
    Guys i had worse baterry on 8.0 ...but now i found the solution, go to the application menu....tap on every app in there , enter the battery menu for each and every app and disable use app in the background..... its incredible, the SOT that i had on nougat its the same on oreo now.....trust me this does give wonder results.....
    1
    This how they make you feel your device needs an upgrade to their latest s9 . Imagine how bad it would be if S8 had better battery life than S9 .... everyone even now would buy S8 for half the price .
    After a ton of messages in forums they were forced to fix the airplane mode but now you need to prove the bug which is more difficult ...

    I think someone could try porting the nougat modem/radio package to current build and check for standby drain, if this works. But a root is required and I dont want to root my phone for this.
