Samsung S8 Oreo - Battery Drains FAST
- Thread starter update_king
- Start date
Standby ( gsm only ) draining is also crystal clear , the same bug in airplane mode : in this mode it can also consume 20% in one night
this consumption is not present in the Android battery statistics
the LTE modem is buggy, they fixed the battery drain at 50%

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.
You cannot change anything without root . But we as users are not supposed to find the solution . Samsung have to provide the fix and make battery great as it was on nougat . Imagine that even if the fix is simple not even 1% of S8 users will read it here and continue using the phone with the bug .
I'm not 100% sure but I think that every change to the firmware needs root since you have to unlock the bootloader . But even if you do this (if it will work at all) I think you will face more problems
Yeah I am going through this to. I was going to replace it using the insurance I have on my phone. I thought the battery was dying or something. Im charging it like 4 times a day and yeah, its so hot it burns my hands to hold it. Taking out of case will cool it down but something is very, very wrong. If they dont fix this quick, they just lost a die hard fan.
My phone, Galaxy S8 BTU version UK, is suffering from increased battery drain since last update too.
Not installed any new apps or anything that could drain my battery. On standby, not being used at all it is dropping 5% per hour even in Safe Mode. Cleared phone's cache, apps cache. Tried safe mode. Still the same. Before last update it would drop 5-7 percen over night. I left my phone with 35% battery at 10pm last night, checked it at 1am and it was down to 20%.
My battery life used to be really good, now I can't make it through the day.
Security patch level 1st August.
Now, with mobile data disabled my battery life comes back to normal. I thought that maybe there's an app that's using mobile data in the background and that results in higher battery usage, so I disabled background data on everything I could but that didn't help at all.
Only turning off mobile data, or switching to airplane mode fixes the battery drain porblem.
I'm so frustrated at the moment.

I honestly doubt it mate. It's not apple to do such thing. Seriously. My daughter is still using my old S6 and it's still receiving updates and is still running smooth and battery is really good for s6 even tho she packed it with loads of games and apps. So no, it doesn't have anything to do with S9.
Has the issue resolved for anyone? Because it's November now and I'm still facing the same battery drain trouble despite of trying everything mentioned here in this thread.
Nougat S8 Battery life
Guys I am still on Nougat because I get good battery life according to your reports.
a) I get 100-30% with 3,23h SOT , 2h calls and 1,5h internet 4G (black screenshots).
b) I can barely get 5,21h SOT if don’t charge it until 18% or something. (white screenshots, internet full Wi-fi, no 4G) I usually charge at 30% cause I want to maintain good battery life.
Have you guys experience any similar battery life on Oreo or Pie beta? Can someone gives as some feedback (screenshots) from Pie Beta?
ps. how can i upload images from desktopsite??

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.
