Standby drain

[XDA_RealLifeReview]

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!

Hello. I've recieved my mobile phone about week ago and there is one problem that annoys me. While the phone has lcd turned off, it drains a lot of energy. For example, yesterday I slept 7h and the battery decreased from 80 to 50%! I've tried almost everything, offline mode, aod off, battery saver mode etc. Any solutions?

Not that much

I think it's a lot ! I've seen many baterry usage screenshots and I was impressed. But mine is some kind of joke. I can't even use my mobile phone often at work because it's dead from 8 to 16, with all options turned off - aod, sync, gps etc. Also with baterry saving mode. Please guys, there must be a way to fix that.

Maybe try and disable bloatware using BK package disabler. It helped for me after disabling a few things

Unfortunately it did not work. I've tried everyrhing..

with only wifi and sync on, battery drains 3% from 11PM to 6AM

 

[bluheart]

4G on
Wi-Fi on
Sync on
Over night From 12 to 8am is 2-3%
Not more.

there's a hundred settings for better battery life, putting apps to sleep, app background data, app data while data saving, notifications, permissions, etc etc etc....

Change network mode to 2G only. You will see standby consumption go from 1-1.5% per hr to .3-.5% per hour guaranteed. Obviously more drain if using always on display and/or other heavy features. Works perfect for me as my s8 is my secondary phone and don't need 4g.

ps. sot currently was like 6 mintues so didnt post screenshot of that, although im able to get around 5-7hrs sot with about 24hrs total use time. Also rom is renovate ice note 8 port ver .1 all stock settings otherwise. Also i got pretty much the same battery runtimes with stock or custom roms. Same usage with lte/3g/2g setting enabled got me nearly 5/6 hrs sot with around 16hrs total usage but really standby was affected by this setting change.

how much would it be with AOD on ?

Snapdragon S8+ rooted.

Not touching the phone, I lose about 10% per hour. A thirty minute drive to work, with Pandora the only app in use, it runs through somewhere between 15-20%. I've tried everything, including telling its mother and using the kitchen sink, but nothing helps. One day we weren't busy at work, and I forgot my charger at home. By 11am I was at 9% (that's after leaving the house at 7:30am) and had to make a run to Walmart for a charger. On a normal day, I have to charge it 2-3 times. On an extreme use day, I have a constant tether.

I lose 3% or so over 8 hours of sleep. Make sure you go through your battery management and options to end draining apps when left in the background.

Stock US unlocked S8+

I'm going to leave my S8+ (unlocked) history so that others can relate and solve as i did:
Bought mine with a German ROM (DBT), and as soon i as connected it to Wi-Fi it got updated to QH3 (latest).
Notice immediately a "Android System" drain that would take over almost 50% of phone sleep time. After some days decided to a "Reset / Factory default" but same story, drain ...
Solution ? Flash different region software (PHN - Netherlands - G955FXXU1AQI7 )
Now it sleeps like a baby and "Android System" remains very low.

Imm experiencing huge battery drainage since the new firmware update......no clue why

Oh and my phone is warm in idle and becomes quite hot when doing low intensity tasks such as loading this site

If this true, I may give up to purchase one. I don't like to bring a power sink. And there is not always have a store that I can charge my device.

That's been my, my son's, and several other people's (in the root threads) experience. There are a whole slew of people that have great battery life with root, but mine is abhorrent. I actually went back to stock, and have been astounded how much longer the battery lasts compared to having it rooted.

Use Tasker!

with only wifi and sync on, battery drains 3% from 11PM to 6AM

Program Tasker to switch off all internet access, auto sync and wifi and Bluetooth. Once switched on, the phone will regain all functions. In a 12 hour shift, with occasional use, I lose about 20% of battery power.

I like Galaxy S8

This is best phone I every wanted. Galaxy S8 is best device in its own. No one can beat it.
