Standby battery life is okay. But when screen is on I feel like is much worse than Nougat >:( And also facebook app is much slower to open with this new update. Honestly, I was loving my phone and now I am starting to get mad with it.
[Samsung Galaxy S8 Questions and Answers] adj998:
A lot of this also depends on which Oreo build you're on. CRB6 apparently has great battery life and signal, whereas CRB8 has a bug in it when it comes to charging all the way to 100 percent, at least for the G955 users. Personally I get about 6 hours of screen on time, that's with Spotify running all day, or my mobile hotspot is on all day

After getting the Oreo update on my T-Mobile Galaxy s8 I noticed that my battery drain is about %30 faster than it was on Nougat!

I think that Samsung is forcing us to upgrade to Galaxy s9, just like Apple does with iOS updates. ;)
[Samsung Galaxy S8 Questions and Answers] frankpicone:
I received the Samsung Experience 9.0 and Android Oreo 8.0 update on March 25th 2018. I too was experiencing an abnormal battery drain where I had to charge my phone midday. After reading some of the posts on here I went digging thru the Settings>Applications and scrolled thru each app to find that Bixby Global Action was consuming 40% of the battery while running in the background. If you click on Battery under the apps info you can disable Allow background activity. I'm hoping this helps but right now I can't see why it wouldn't. I have a Galaxy S8.
[Samsung Galaxy S8 Questions and Answers] RR-99:
I'm running the official Oreo update. Definitely using more battery power in standby.

I have Bixby and most Samsung apps turned off.

Very disappointing.
[Samsung Galaxy S8 Questions and Answers] Selee:
I use an S8 and updated to Oreo 4 days ago and my batteries life is baddddd. I did not installed anything new since the update and I even disabled some features since the update. I did a few factory resets and it's still the same issue (cause Oreo is the one that gets installed) For example last night my phone was at 68% when I went to bed and 6h later it was at 30% up on waking up!!!??? Wtf?
[Samsung Galaxy S8 Questions and Answers] Duskfall89:
I updated to Android Oreo and I am also experiencing abnormal battery drain on my S8. My device is not rooted or anything. Sometimes when I look at the battery consumption, there is listed Google Play Music, Google Play services and Google Maps, each of them with 3% consumption. The funny thing is that I didn't use them at all?!
[Samsung Galaxy S8 Questions and Answers] chaki-:
If you don't use them disable all but Google play services.

See how it behaves.

Did you do a hard reset?
[Samsung Galaxy S8 Questions and Answers] Duskfall89:
I use Maps only when I need it.

I didn't do any hard reset because I don't think that will fix the issue as I read a lot of posts where people did the reset and it didn't change anything to the battery drain. So hard reset would be the last option I am willing to take.
[Samsung Galaxy S8 Questions and Answers] mitkomit:
Thanks it was really the samsung email

It was samsung email...i upgrated it and battery eating disappeared.
[Samsung Galaxy S8 Questions and Answers] Duskfall89:
I have 0% battery usage with samsung email so I don't think that is the problem on my device. What do you mean by "upgraded"? Updated samsung email?
[Samsung Galaxy S8 Questions and Answers] rajone9:
I haven't Samsung email app on my s8 with Oreo

Inviato dal mio SM-G950F utilizzando Tapatalk
[Samsung Galaxy S8 Questions and Answers] chaki-:
Yeah, i know what you mean, but nevertheless a hard reset is a must after a major update. It is a pain in the ass to configure everything from scratch.

Problem is, everyone is typing lot of nonsense here and we get confused. Every phone behaves so differently that you can't tell if that gonna work or not.

You don't like it? You can always revert to nougat....
[Samsung Galaxy S8 Questions and Answers] coop3422:
I want to upgrade to Oreo, and it just got pushed to me via OTA, but I'm not willing to take a big battery hit, nor do I want to do a hard reset just before vacation. Looks like I'll be putting it off for a week or two.
[Samsung Galaxy S8 Questions and Answers] Robert3750:
After the big battery hit I took when I went from 6 to 7 on the LG G5, I'm not "upgrading" my S8 to Oreo for a LONG time. I don't understand why this always seems to happen with these "upgrades".
[Samsung Galaxy S8 Questions and Answers] Zimbart:
I just checked my apps, and there were 2 or 3 bixby apps that all said they used 43% battery since this morn!!! U can click the dots at the top right and uninstall their updates and they go away. I am thinking this has to be the culprit. I will let you know tomorrow after a full charge how it goes.
[Samsung Galaxy S8 Questions and Answers] stondec100:
I can confirm that Samsung email was also a source of enormous battery drain on Nougat.
[Samsung Galaxy S8 Questions and Answers] blindskater39:
On Nougat I used to charge my phone once a day or even 2 days with the same settings on 1080p, no BT, no NFC, no AOD, and mostly indoors so my brightness is not high. Android system used is taking up more power than the screen. So only getting 3 hours SOT.

Update: Followed this guide https://www.theandroidsoul.com/how-to-fix-battery-drain-issues-oreo-update/ and my device seems to have improved on battery life and feel snappier as of day 1 so far
[Samsung Galaxy S8 Questions and Answers] Daedalus94:
My solution

This may not work for all and I don't know if it'll cause any other issues, but I went to Settings-Apps and turned off background data usage on everything except textra, Amazon flex, and Google maps. I also force closed anything I wasn't currently using. I'm at 4hrs past full charge and still at 88%.
[Samsung Galaxy S8 Questions and Answers] Rajnus:
I had battery drain. As written here I have updated email app and disabled 'keep mobile data turned on' . I have fully charged the phone and left it over the night. I had consumption 0.9%/h. This is quite ok.
[Samsung Galaxy S8 Questions and Answers] David_Cleworth:
Hi Guys

I experienced HUGE battery loss as soon as I updated my S8 (Exynos) to Oreo. I tried all sorts from this thread - disabling Bixby, disabling permanent 4G connection, reducing resolution, disabling stock email, plus all sorts of other things. All things we should't have to do when upgrading to a newer and improved version of Android. When installing Oreo I'd wipe the phone and clear the cache multiple times as well. None of this worked after a few attempts, the battery was draining fast. I wasn't prepared to turn off BT, NFC etc.

The thing which solved it for me was to install Oreo as a completely clean slate all the way through the process - I didn't restore the Google backup OR the Samsung backup. A bit of a pain because I had to manually put all the apps back on and set them up manually again, but the battery life is back to how it was on Nougat, really good, easily a day's heavy usage. Hope this helps some of you. Something being restored from the old apps either from Google or more likely Samsung, was conflicting and munching battery, but it didn't show that obviously under my battery usage details. I was so close to going back to Nougat, that's how bad the battery life issue was becoming. Glad I tried this last attempt because Oreo has some fantastic features.
[Samsung Galaxy S8 Questions and Answers] resulnaki99:
what do you mean by clean slate all the way through the process? Do u mean a hard reset and reenter everything? I think others have tried it already. im not sure what you meant by that.
[Samsung Galaxy S8 Questions and Answers] OgreTactic:
FFS why can't anyone on android "developper" forum figure out clear explanation (not even solution) but explanation for that. I can tell you exactly why or what are the process that make an iPhone battery life go down, and you can find plenty of description and (jailbroken or not) solutions.

I'm NOT on Oreo and didn't want to upgrade for that reason, having had consistent and good battery life for 3 month, and suddenly since a couple of days the battery life has gone completely down to crap with the same usage and setting, and most importantly I DID NOT do the update. What am I missing?
[Samsung Galaxy S8 Questions and Answers] mattguy:
I don't even use Bixby and it wasn't showing up in the battery stats, but I went to the app list then Bixby global action and WOWZA! 61% battery usage!

Disabled.
[Samsung Galaxy S8 Questions and Answers] David_Cleworth:
Sorry, yes I meant hard reset, full wipe, clear cache - and then once Android 8 is installed, reinstall every app manuallly, not via a previous backup from Samsung or Google. It definitely helped me, hope it helps others. Just a very long winded way to try it out to test if it worked unforunately :( Good luck!
[Samsung Galaxy S8 Questions and Answers] jimbob68:
I have Oreo CRC7 build on S8+ (exynos). Battery draining fast. did all the recommended things..no help. Then found the androidsoul article that says : "From the home screen of your device, navigate to Settings – Apps.

Scroll down to find the Google Play Services app and open the Storage

Here you will be able to see the Clear Data and Clear Cache options, so use both of them to refresh the app.

Follow the steps above to find the Google Play Store app and use the Clear Data and Clear Cache options once again."

boom!! My battery drain issue is gone and now great battery life on this latest build. Hope it helps someone.
[Samsung Galaxy S8 Questions and Answers] resulnaki99:
nothing works. stutter is still there. i have stutter and lag, especially going back to home screen (even with animations off). battery life is terrible. i was 97 after having my phone on for an hour with very minimal use, and not its much lower with same exact usage. phone heats up as well. this oreo update is def not stable, they should have tested more. i dont wanna wait few hrs to download nougat from sammobile either. samsung plus or smart switch should have that option automatically. I love samsung tech and products but unfortunately their general service and their customer service is atrocious. once you buy their product, its over for them. they dont give a damn.
[Samsung Galaxy S8 Questions and Answers] eduardi:
Hello,

I belive everyone solve his problem by now since now one has written 2 days now.

Here how my problem was solved: I had the g950fxxu1crb7 version since now 2 days and that is the version with the battery drain issue.

When I got the OTA update with the g950fxxu1crc7 version that solved the problem. From the beginning when the update was done I notice the difference. After the update I did this:

Turn off the Galaxy S8, and then press and hold the Volume Up, Bixby, and Power button simultaneously.

Release the Power button when the Samsung logo appears, but continue to hold the Volume Up and Bixby buttons.

On the Android recovery screen, use the Volume Down button to navigate down to wipe cache partition and press the Power button to select it.

Use the Volume Down button to select Yes — delete all user data, and then press the Power button to confirm.

Wait for the reset to finish and press the Power button when prompted with the message to Reboot system now.

Now the battery is better and overthe night the battery loses 2 % and before the update was 10% or higher. On daily usage before iI could not pass the day but after for example last night it was set 40%.

I'm not a heavy user.

Good luck
[Samsung Galaxy S8 Questions and Answers] RR-99:
No, I'm still getting the same poor battery life. And I see others are still complaining in other threads.

I've tried all suggestions posted but still getting about 25% less battery time than with Nougat.
[Samsung Galaxy S8 Questions and Answers] resulnaki99:
Everyone has already done that. Its just a bad update. They need a patch real soon. My battery is dying faster and my phone is lagging. Nougat was much better.

[Samsung Galaxy S8 Questions and Answers] jodaboda:
S8 on xfinity/verizon usa. I had awesome battery life under Nougat. Oreo F-d it up bigtime. It would drain over 30% overnight. Tried disabling apps, adhell blocking all kinds of stuff, background data off, wipe cache partition. No luck.

Did full system reset (I did it via settings), and everything seems great now. Only about 2% battery used overnight, full charge lasted 24 hours, including an hour of navigation.

I also keep mobile data off all the time, but that was the case before as well.
[Samsung Galaxy S8 Questions and Answers] Chickenpaiz:
I realised after oreo update, in the

Setting>connection setting >more connection setting turn off the nearby scanning

And

Setting>lock screen and security >other security setting turn off send security report

This may be the cause of the battery idle drainage issue

Youtube - 13min
[Samsung Galaxy S8 Questions and Answers] simes6600:
my oreo battery life was awful. i googled extensively and disabled bixby, still no luck. did i cache wipe but didn't factory reset simply cos too much hassle to restore.

so...i looked at what was eating at my battery. media. extractor (or something) was eating my battery big time. Google search pointed towards a corrupt file on my sd card. i removed my sd card and the prob still persisted.

so. another suggestion linked to the media. extractor prob was to disable chrome (which i did with bk manager, play store). since then my battery has been awesome on oreo. or at least the same as nougat.
[Samsung Galaxy S8 Questions and Answers] k818mn1:
My battery life after updating to Oreo was dreadful, about half what it was on Nougat. I tried all the suggestions in this thread about disabling Bixby services, wifi calling, etc, but with no improvement.

Finally, this past weekend I performed a factory date reset and restored all my apps. Success! Battery life is back to normal.
[Samsung Galaxy S8 Questions and Answers] resulnaki99:
All the solutions Im reading are temp solutions and might work for some, and not work for others. I dont need to turn off my Data or anything else for that matter to get better life, especially since I didnt have do to any of these while using nougat. Terrible update and needs a patch soon. I did a full reset again without restoring any data, which took a long time, its definitely much better as far as battery goes, but the subtle lag is still there. I dont need to reset my phone bunch of times to get it right you know. Whats to point of back up if AI have to restart all over again. Ive said it before, Samsung has terrible customer service, and terrible back support for their devices even its just a year old.
[Samsung Galaxy S8 Questions and Answers] Amartier:
Did you just use the Google or Samsung restore? Or did you do a clean restore, redownloading each app one by one?
[Samsung Galaxy S8 Questions and Answers] Nightwish1976:
I also had this problem after updating to Oreo.

Just performed a hard reset and restored the apps manually, so far the battery life seems to be back where it should have been.

Later edit: poor battery life again after a couple of days.

[Samsung Galaxy S8 Questions and Answers] gliz:
Hi, I noticed that my Oreo (I upgraded to Oreo just 3 days before) battery drain had gone after turning off background usage of Android OS and Outlook (if you have).

Notice when you open battery usage, wait until it shows Android OS, press it and turn off its "App background usage" or something like that toggle, same with Outlook.

After doing it, it does not take effect instantly but after using for some hours and had some full charges, the drain had gone, before it was draining 100% fast to 97% in less than 30mins while screen is turned off, now it does not anymore, just the same with what I had with Nougat. (still 100% like after around 1hr or more with default mode - optimized).

You would think that disabling Android OS background would give bad results - I thought so too but it doesn't. They would not enable turning it off it would, won't they? As well as Outlook, I use Outlook app for my work and thought turning off background processing won't give me notifications anymore but it still did!.. I wonder what kind of background it suppresses as it it still updates automatically as long as i am connected to the internet whether data or wifi.

I hope this works for you or for anyone as well. Just remember effect on mine is not instant, I had like 2 cycle charges before I noticed the effect.

Thanks,

gliz

My HTC 10 has been having major issues since updating to Oreo 8.0. If I leave my phone unplugged from the charger it will shut off as if the battery is dead. It happens when I have anywhere from 40% to 73% battery life. If I try to turn it back on without plugging the charger in it just shut back off and shows a battery life of 1%. If I plug it in and then turn it back on it still has the same battery life as when it shut off. Also if I try turning it back on to many times without plugging it in it messes up my Google account access and HTC account access. Is there a fix for this issue, because I know it's not good for my phone to constantly be plugged in?

Just installed CRD4 through Odin the other day and have only 1% battery drain (100% to 99%) in standby for 8hrs overnight. Also getting 4.5+ hrs SOT and 20+ hrs between charging. Configuration is: AOD-off, WIFI-on, DATA-on, bloatware and Bixby removed, WQHD, NFC-on,Location-Hi Accuracy, and no adjustments to background use for apps. So far, so good.
