When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy S8's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

Then, drop a comment if you have anything to add!

I lose about 3% an hour while I sleep. No other phone I've owned has drained that much.

I'm sure it's an app sucking the juice out of it.... I've restored it back to clean factory setting 3 times, after a few weeks it always goes back to about 3% an hour.

I uses Gsam battery monitor, but it shows nothing out of the ordinary other than: System, Samsux DeX (which I don't use), or the Kernel is usually really high.

I LOVE everything else about this phone, other than this.

I have the same problem, with mobile data ON...phone drains 3% overnight (8hours).
My old Samsung S6 drains 0-1% over night with cell radio on.

all draining apps optimized with brevent.
battery draining apps disabled with BK Disabler + some gapps services disabled
volte + wifi calling off.

gsam and better battery stats show no problems.
But Android Battery statistics show high cell standby drain.
I think it is a modem issue.

I have got an G950F with DBT Firmware

Not per hour... but over the whole night.
No AOD.
Disabled bixby and all bixby services.
Disabled anything related to Samsung's voice services.

I lose 3% an hour too. I have an old Galaxy Note 3 on Resurrection Remix 5.8.3 (Android 7.1.2) that lasts 25 days on standby. It's the stupid LagWiz bloated OS!

I was having massive standby drain, even with Greenify, then I set up the phone with these settings https://www.xda-developers.com/the-g...my-experience/ (see "Linked a screenshot) and uninstalled Greenify (read somewhere that it can get into a loop of auto hibernation which drains battery) and wow! from 4 to 5% an hour to 2% over 7 hours so am very chuffed!
