[Q] Android System = 49% of overall usage?

Just yesterday I noticed that my battery was draining crazy quick while it was in sleep mode. I don't have any background syncing going on other than auto-update for a weather widget once an hour along with the core Google things like contacts, email, calendar, etc.
Usually the screen has been the largest contributor to draining of the battery and via betterbatterystats, there's no abnormal wakes going on.
I did a reset of the phone and I've now disabled 'Data Network Mode' as I'm primarily on Wifi right now. It seems to have fixed itself so far but I'll know better tonight.
Is this a conflict within the OS itself (rooted on Infused V2.1.0) or something from having 4G enabled when I'm in an area where I typically only get 1 bar? Either way, it's a huge draw on my battery...

From what I've heard/read this is a random bug caused by gb, not common at all but ocassionaly android os will go nuts and suck down your battery. Resolutions I've seen posted have just been power off, remove battery, re-insert battery, power up = issues reoslved.

Hmm, I would say try the battery-pull method first. If that doesn't fix it, maybe try flashing back to stock via ODIN and then re-flash Infused? Just an idea.

[Q] Please Help ! Android System Battery Drain on Nexus 5 after KitKat 4.4.2 update

Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.

Not a lot that can be done without knowing the cause. Consider factory reset?

I am hoping I don have to resort to factory reset and can wait for the 4.4.3 update but I guess my patience is running out.
Thanks for your help.

My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.

having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.

You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.
Sent from my Nexus 5

I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.

Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....

I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.

Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.

Update
Please refer to the OP for update. Thanks all.

battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?

It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)

Tips to For Increasing Battery Life on the Galaxy S9

Sooner or later you will find yourself looking to save some battery life. here are a few ways.
1- Disable Always-On Display
2- Put apps to sleep
3- Lower screen resolution
4- Use Dark wallpaper/ Shorten screen timeout
5- Auto Screen brightness off
6- Turn Wifi off when not in use.
The video shows how to do these if you're not familiar with the settings on the phone. Feel free to add to the list.

Honestly I don't get any better battery life when using the phone at FHD rather than QHD. If anything it seems to me that the software had become so optimized for QHD that it may actually turn out more SOT and general battery life times. But that may just be my experience, not sure

Every year someone makes this joke.

Here's a link to one of my recent posts of all the things that I disable. They all add up...
Also, never let the phone fall below 10% if you're able to control it.

Why not let it fall below 10% ?

I've yet to see any conclusive evidence that the battery life improves when you lower the resolution. Best argument I've seen for doing this is an improvement in scrolling and animations

And every year I laugh at it because every year people buy the best phone on the market and then make a list of how to disable everything and cripple it so they can squeeze another hour of battery life in.
I get it because I used to be obsessed with battery life but then I realized I have chargers, wired and wireless, everywhere.

Install BK Package Manager and disable all bloatware.

Quick tip for excellent battery life:
1. Go to wifi advanced settings and tell your phone to turn off wifi during sleep unless the phone is charging. ( helps a little)
2. Turn on data saver on your phone (so when ur phone is off it updates using ur data instead of wifi. since wifi is off during sleep if u did step 1)
3. Go into data saver settings and give unlimited data access to specific apps that you use such as Google play services( for account and data backup) messenger, gmail and any other important apps)
4. Go Into your battery settings, under unmonitored apps, remove every app sitting in there. Then go into always sleeping apps, and set everything to sleep except the apps you use the most and want to receive regular notifications for. (So of course Google play services and Samsung services if u use those to back up your data and some messaging apps and mail apps, messenger, snapchat etc)
If you do these steps you are preventing your phone from randomly syncing information. (The biggest culprits being the apps you don't really use such as the Samsung apps like AR EMOJIS, ant services, galaxy app store, etc).
this has saved me significant battery life. Averaging about 8hrs screen on time and get abt 2 days battery with relatively heavy use. (Inbox,YouTube, instagram, snapchat, bleacher report etc).
Hope this helps

Are you inside a building during most of the standby time? Or anywhere that would cause a weak signal? I found inside large building or places where cell reception is low causes a lot of battery drain during standby

No just no. Feels like i disabled every app there is. 4 hours sot. Maximum 24 hours total time. Draining 10% minimum during sleep if left unplugged for (7 hours) i put every app in sleep. Cant find samsung ar etc in (always sleeping apps tho) i set everything except for messenger. Snap.waze. bbs and spotify in always sleep. Still not sure it will work. Aod on. Auto brightness on.. maybe i shouldn't complain. But when people get 7 hours sot i feel like i need to complain. I had bad battery time with my s7 aswell.

I understand why you would be skeptical. i will try to get a screenshot the next time i have a chance.
Another thing I did notice is screen brightness is one of the biggest battery killers on the phone. Maybe try power saving mode but only use the -10% brightness option that should help a little bit or manage your brightness manually. Hope that helps

I'm pretty disappointed with the battery life on my S9+ to be honest. Today for example, with minimal usage, after unplugging at about 9:30 am I was down to 35% by noon.
I've recharged it and now left it sitting - it is consuming power at a rate of 1% per 10 minutes, just sitting on the table without me using it. I'm at home, with a strong 4G signal, WiFi router is in the same room, and Bluetooth is disabled.
I moved from an LG G6 to this phone because I was tired of the LG hanging and stumbling to do basic things, but at least the battery lasted a little longer - I could sit it on the table and I'd only lose a couple of percent over the course of a few hours.

How To Make Your Battery Life Better, And Why Does Your Battery Life Suck?

Hey guys! Posted this on Reddit, and many people loved my guide and explanations, SO Posting this here and hope this helps everyone with issues about the battery etc.
After a few days of testing these are my tips to you guys, AND my experience how I got atleast better battery life to some extinct.
Now to the basic charging tip as some, and some not know. Charging between 30% to 80/90% is smart. Wears the battery much less than 0 to 100% for instance. Read this up further if you need, not gonna talk about this forever.
To the Nokia battery part. So first of all MANY users have reported Adaptive battery and auto-brightness are bugged and drains more than they should. Well this is true. DO NOT use adaptive battery if you experience bad battery life, and especially not auto-brightness. Why am I saying do not use it? Simple. It does the opposite, so is reported many others. I tested this carefully when sleeping to test the idle drain just by having the Android system installed and a few apps. I got a drain of around 10 to 13% through only 9 hours of sleeping. This is bad. However when adaptive battery turned off, no apps restricted I tested for many days and ended up with only a drain of 2 to 4% through those 9 hours. Will it help you? I dunno, but worked for many.
EVENWELL APPS. Usually bloatware. Only few apps from evenwell is needed for the OS to work. The powersaving g3 package from evenwell, which is a third party that Nokia has done some kind of deal with. The powersaving was suppose to help, but instead made things worse. Making alarms useless etc etc that has been mentioned on the forum. It kills apps even wehn whitelisted or when the phone was locked for a while.
Hook up the nokia on your pc and use adb. Uninstall this package, and almost all evenwell packages installed. Atleast powersaving g3 package, as it's known to drain. Most are bloatware, however you need to be careful not to delete the wrong packages, as they can only be restored by factory reset. Which packages to uninstall depends on your needs. Please remember to check on xda to find a guide on this, if not I will find it for you. This can help a lot just by using some of your time to remove stuff you might not need.
Turn off the aggressive 4g switch in developer settings. It will set 4g to always active, and you are better off just having it off. Should be called something like "Mobile data always active".
You got facebook? Well many has reported that facebook drains a lot, as it uses many services to communicate with the phone. I usually just use dolphin browser and have facebook logged in
Now for me I have these settings mentioned above, and I use my phone a lot, I get around 2 to 2,5 days of use of the phone just by doing these things. Uninstalling many evenwell packages helped a lot too. If none of these tips help you, then deleting caches can help. If not backup and factory reset the phone. If that does not work too, then it could just be the Pie updates being drainy for you. Hope this helps anyone ! Ask me if any questions!
Question: When turning off adaptive battery it keeps turning on after a while. Answer: have atleast 1 app restricted and adaptive battery on. From there turn it off and let the 1 app stay restricted (it really isn't). Now it should hopefully stay off.

Thanks for tips.
I have a request for you. Could you make a list of evenwell apps which are 100% safe to uninstall from N7+?

Now to the basic charging tip as some, and some not know. Charging between 30% to 80/90% is smart. Wears the battery much less than 0 to 100% for instance. Read this up further if you need, not gonna talk about this forever.
To the Nokia battery part. So first of all MANY users have reported Adaptive battery and auto-brightness are bugged and drains more than they should. Well this is true. DO NOT use adaptive battery if you experience bad battery life, and especially not auto-brightness. Why am I saying do not use it? Simple. It does the opposite, so is reported many others. I tested this carefully when sleeping to test the idle drain just by having the Android system installed and a few apps. I got a drain of around 10 to 13% through only 9 hours of sleeping. This is bad. However when adaptive battery turned off, no apps restricted I tested for many days and ended up with only a drain of 2 to 4% through those 9 hours. Will it help you? I dunno, but worked for many.
EVENWELL APPS. Usually bloatware. Only few apps from evenwell is needed for the OS to work. The powersaving g3 package from evenwell, which is a third party that Nokia has done some kind of deal with. The powersaving was suppose to help, but instead made things worse. Making alarms useless etc etc that has been mentioned on the forum. It kills apps even wehn whitelisted or when the phone was locked for a while.
Hook up the nokia on your pc and use adb. Uninstall this package, and almost all evenwell packages installed. Atleast powersaving g3 package, as it's known to drain. Most are bloatware, however you need to be careful not to delete the wrong packages, as they can only be restored by factory reset. Which packages to uninstall depends on your needs. Please remember to check on xda to find a guide on this, if not I will find it for you. This can help a lot just by using some of your time to remove stuff you might not need.
Turn off the aggressive 4g switch in developer settings. It will set 4g to always active, and you are better off just having it off. Should be called something like "Mobile data always active".
You got facebook? Well many has reported that facebook drains a lot, as it uses many services to communicate with the phone. I usually just use dolphin browser and have facebook logged in
Now for me I have these settings mentioned above, and I use my phone a lot, I get around 2 to 2,5 days of use of the phone just by doing these things. Uninstalling many evenwell packages helped a lot too. If none of these tips help you, then deleting caches can help. If not backup and factory reset the phone. If that does not work too, then it could just be the Pie updates being drainy for you. Hope this helps anyone ! Ask me if any questions!
Question: When turning off adaptive battery it keeps turning on after a while. Answer: have atleast 1 app restricted and adaptive battery on. From there turn it off and let the 1 app stay restricted (it really isn't). Now it should hopefully stay off.

Thanks for your effort to put this together.
I am not sure about Evenwell apps and I'll explain why:
- I did not uninstalled or blocked Evenwell app. What I did was to turn off battery saver (maybe it's the same thing?) And that improved battery life a lot.
- I am getting 2.5 - 3 days battery use for a full charge (100% charge - did this with every phone I had, never had an issue with battery).
- I do not have issues with alarms, fitness tracking, notifications, etc.
- I agree with disabling 4g always on - that helps a lot
- definitely agree with Facebook.
- adaptive battery is still on.
I am on Pie, December patch.

And a screenshot for battery saver

Thanks i actually thought that the Android One meant a debloated system. So i never even cared about checking the system apps. Well now my phone is debloated! Almost as many ****ty apps that Samsung has.
It runs much smoother in the UI too.

After update to 9.0 my battery life became very bad... SoT was barely 2.5h.
However, i found out a way to fix it!
Deleting facebook app, and disabling battery aid improved it alot, disabling sync can also give you a little boost .. Deleting facebook app helped the most. I get between 5-6h SoT. Cheers!

SoT after my tricks?

You should always remove facebook and messenger app and use facebook lite and messenger lite instead

what's the best solution for now to increase sot?

I have a Nokia 7 Plus (Europe) with Android Pie and I have no application problem killed. I do not see any difference in disabling the battery management as well as "evenwell".
What empties my battery is "Google Play Service". Almost 2% per hour is way too much for a device on standby at night.

You need to clear cache from Google Play services or perhaps wait for a new update from Google. I had the same issue , however clearing the cache helped me restore battery to a respectable level.

Battery life is awesome for me. It lasts 9 hours in 81% (from 98% to 17%) screen on time, wi-fi always on, without gaming, location disabled (it takes a lot of battery)

After updating to March security patch (Android Pie), battery life returns to great! Adaptive battery can now be permanently turned off and I'm getting average 3 days of normal use on a single charge.

Question Did anyone notice the huge standby battery drain? Any way to measure what causes it?

First off, I love the phone and I'll keep it, but ever since I got the phone I've been wondering why it's draining so much in standby. It's my first Samsung phone since 2011, so naturally I assume it's Samsung apps/services that drain? Especially since I don't use any new apps than on my other phones and in the battery stats it doesn't really show any user apps that use a lot.
Anyone has way to measure what system/user apps drain during standby? Or even better, any dev that could do a deeper dive into this?
For example, I just lost 32% battery while sleeping for about 8h, it has never been this much on any other of my previous phones (OnePlus Nord/Pixel 3a/Pixel 3/Pixel 2).
In fact, my OnePlus Nord with 815mAh more than the Flip3 is currently on last charge 3 days ago (it doesn't show me hours anymore) and 2h35m SOT and 25% battery left. On the Flip I just now got 17h with 1h30m SOT and 5% left. Settings all similar besides location accuracy turned off for the Flip as that was a massive drain.
Something must be unintentionally draining the battery during standby and I really hope one of you smart guys can find it. Or Samsung fixes it with an update..

I disabled AOD and any unnecessary account sync processes. It's only drained about 2% in standby the last 5 hours, but there are still some things to finish configuring.

If have AOD on a schedule so it's turned off during sleeping, account syncing I don't have anything that I can turn off and I never did on any previous phone

How old is your device? You got to give it some time to settle. I had 15% battery drain the first night, after that it went down to 5%.

The first step in improving the battery is to remember that this isn't any other phone. You may want to explore what options are available and what all you have enabled. By default, almost everything is on to show off all the cool new features that make this a Flip 3, not a OnePlus Nord.

Which Flip features are in use during standby though? During standby it's just another phone

Not true. Samsung has a bunch of features still in use.
Settings -> Advanced features -> Motions and gestures has a whole collection of things that are still running when the screen is off (and most aren't useful to the Flip, but came from "another phone").
Settings -> Cover screen allows you to disable turning on the screen when notifications arrive, if that is not something you need.
Also, unless you are using the app to lower the refresh rate, you may be running a bit high when idle.

I've turned a few things off there, but a lot of them OnePlus has too + a few more, which I had all enabled

I didn't really get any notification during last night, so I doubt this was the culprit

Yes I'm using that app and have it set to 48-96Hz
Appreciate the help, I believe there must be something that's unintentionally draining and while I went through every single setting in the beginning, I'm still very new to OneUI (and also impressed how far it came from the TouchWiz ****show)

One thing I always forget is that a lot of those features are running services and polling when they're enabled. Even though I'm not touching the screen with the tap to wake enabled, it's constantly waiting for that tap when it's asleep. Any one isn't a big impact, but Samsung has so many "convenience" features that I end up wasting battery to never use.
The calibration period is also horrible. Android 11 is slow to calibrate the battery and Samsung is worse. You can get a good idea of what is draining battery by going to Settings -> Battery and device care -> Battery. That may help find out if it's a renegade app.
One thing Asus does that I wish Samsung would embrace is Auto-start management. Some apps aren't efficient at polling for notifications and more than once have been the cause of major drain.
Another one even Samsung admits to be a source of drain is the edge panels. If you don't use them, it's best to kill the entire feature.

I just assumed it's not a big impact as OnePlus has those as well, for example draw a "V" on screen for flashlight or ">" to skip song besides the regular double tap to wake and it never appeared to be a battery issue for me before.

Do I assume correctly that some system apps or similar are hidden there? I just did the calculations and the percentages only make up 43.6%. I attached a screenshot

OnePlus also optimizes them better than brand new Samsung firmware. I had a lot of stuff enabled on the Note 20 Ultra that I won't be using for a month or two now.
Some apps are excluded, but it will let you know if it's something not included with the phone.
Another good idea is to uninstall, disable, or "adb uninstall" any bloat you don't use. Besides clearing up space in the app drawer, it kills off services you don't use. A lot of the apps will run services even before you sign in, even though they aren't actually handling any data.

I already went through the list and uninstalled which I 100% knew what it was and that it's not needed, but not sure about 99% of Samsung stuff. Some Samsung apps on the phone I don't even know what they are and when I start them it just prompts to agree to some terms before starting the app... I'll have a look around for a Samsung debloat list

If you have the unlocked version, they allowed uninstall for a lot of apps that were previously locked. A lot can also be downloaded later from Google Play or the Galaxy Store if you change your mind.
I use Firefox, so I uninstall Samsung Internet and Chrome. Members and Health are two big ones that like to run those "please enable us" services. It's a lot of deciding what you might use versus what you can live without.
Another good idea is to add anything you won't use, but didn't remove to deep sleeping apps to kill it's ability to run in the background. It's the closest thing to auto start management without rooting.

So far I don't have much hope sadly. Whole day currently at home and not using the phone much and it's looking like in the screenshot (screen off, loosing almost 2.7% per hour, as comparison my OnePlus is at 0.9% per hour)
https://imgur.com/RLITZwQ
It's 21:21 at the moment and I'm at 54% after 9h 42m (comparison OnePlus with 815mAh more: 7% after 79h with 2h54m SOT)

I'll probably head to bed in a few hours and then report back tomorrow morning how much I lost during the night..

I'm not claiming to have amazing battery life, since I almost considered keeping my trade-in and returning this one over it. I am interested why it is so bad for others, though.

HOLY **** I would love to have this battery life. I'm literally not doing anything with the phone and just loosing so much. I'm pretty much the opposite of a power user, so my phone is in standby most of the time and loosing so much is pretty frustrating.
EDIT: I might have an idea why it's so bad for me, I don't really have reception in my apartment (as you can see on my screenshots), so I assume it's constantly trying to get better receptions, I see 2 bars sometimes, but most of the time 0. I'll keep my phone at the window where I have reception for the rest of the day and see if it makes a difference. (Although the OnePlus has also bad reception, but does have a different carriers SIM card)

Dependencies, dependencies, dependencies... some of those apks just sit there unless needed.
Do not disable apks/services unless you know what they do and what, if any, their dependencies are. Go too far and you'll end up in a boot loop.
What works for others probably isn't ideal for you.
Package Disabler is a better option as you easily toggle apks on/off as needed.
Screen off the serial offenders tend to be Google backup Transport, Framework and any cloud apps.
Try disabling Google play Services at night and see if that helps. You may need to disable Find my Device first as System Administrator if disable is greyed out.
Disabling play services also kills Gmaps and Playstore which are know hogs. Gmail as well to a lesser extent.
Google Firebase, do you need it? If not disable.
Carrier, Google, Samsung and app feedback, disable.
Using power management can cause erratic behavior and not solve the problem. Treat each power hog on a case by case basis instead. It takes a lot longer but yields a cleaner, more stable setup.
Play with it, go through -all- the settings. It's actually quit fun to explore and almost impossible to crash and burn.
