Samsung S8 Oreo - Battery Drains FAST
- Thread starter update_king
- Start date
That you and the rest. I am ok. Previously on nougat I have 4 to 4.5 hours sot with full day 4g or wifi. Now is slightly worse off but i am fine with it.
You are asking for more sot but I was referring to standby .
You have 46% after 9 hours unplugged and it's a beast ???
Try to not touch your phone after a full charge and you will see how many hours it lasts ... that's the problem
I have 2 % battery drop from 00:00 to 7 :00....i think its monster standby ....without always on during this period.
Standby was never a problem for me..... i didnt get this Sot on nougat....just try those changes i told a post back....it does magic

Hi, I noticed that my Oreo (I upgraded to Oreo just 3 days ago) 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,

When I read that someone has SOT 4hous + after 36hour of using and still 40% , I'm sad.
My SOT is max 3 - 3,5h. When is mobile in standby it's cost 0,8% of battery per hour. When is displey on It's 1% per 2,5min. So when I unplug mobile in 10pm, at 5am when I wake up is battery on 94% , when I get to work at 6am it is 90% (with 3min SOT) and after work at 3pm is battery approx 60% and SOT 1h10min.
- VolLTE off, only 3G/2G, 1mail sync every 4hours, resolution FHD+, bluetooth on, wifi on, locationon - economical mode(wifi and mobile site), AOD on...
I would like to have also SOT 4h after 30+hour of using and have still 40%

as stupid as this sounds, do you have an sdcard installed in phone. After taking out sdcard, I get better battery drain to under .7% an hr
My phone is from Germany, but im on Turkey. Installed the latest CRED. There's wasn't any 4G bug. You can try your chance.
I've seen this posted many times over the years but I could never figure out why. Why in the hell would you turn your phone on airplane mode overnight!!?? If you dont want someone calling or messaging, turn on do not disturb.... Here I am once again, some one asked about airplane mode......This just seems odd, as you phone updates and does a backup at night or at least mine always did. Not criticizing just curious what the appeal is of making your device useless during that period of time by turning on airplane mode. Best thing to do is turn off all background data you don't need to use on each app and to not have FACEBOOK installed/enabled, use the browser!! I had a large drain when that app was enabled. I can routinely get 4hr sot and more on times. There has been a battery hit on this god dang oreo though. Nougat would yield me 6-7 hrs sot!! Hope you can fix your battery life. reset your phone and dont restore apps, do them a couple at a time and leave it to see if drain still exists. then add more apps and repeat until you find the culprit. (i have dex and bixby disabled along with a few other apps)
I need airplane mode because I leave my phone next to me (Because I use it as alarm) and don't want the antenna to burn my mind during the night . Does it seem too odd for you ?
I am referring to a specific bug that came with Oreo. It's not my setup but the firmware itself .

Good news ! The latest CRED update fixes the battery a lot and no airplane mode drain ! At last after 3 updates and 3 months with battery drain ,they figured out how to fix it .

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.1
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 left1Guys 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
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.
