Disabling apps may cause huge battery drain.

As soon as I got my phone and set it up, I disabled all the AT&T bloatware in addition to google+, twitter, ypmobile, etc. Phone was always running great, but I kept wondering why I could never get over 3 hours screen time.
Fast forward to this morning....I re-enabled every app that I have disabled, and now I'm sitting at 3 hours screen time with 35% battery left. Didn't change anything else.
So I'm not sure why disabling apps caused a huge battery drain (I thought it would help with battery), but it did for me.
Might be something to check out if you are having battery issues.

Weird. Mine last longer. Check your auto-sync settings?

You said as soon as you got your phone set up you did this. That brings a few things to mind:
1) It sounds like it was your first or second battery charge. You need to fully charge/discharge a couple times before the battery's properly configured and you'll experience the device's full battery life.
2) Being that you just set it up, auto-sync would be working overtime for the first-time sync. You know, pulling in all your contacts, emails, calendar events, facebook everything, and so on, causing a higher-than-normal strain on the radio (either wifi or LTE, doesn't matter) and CPU.
Now that your battery's calibrated and your first-time sync is done with, give'er a full charge, disable the same apps again, and let us know how that goes.

I've checked everything. Everything was OK, so I decided to re-enable the apps to see what would happen and now my battery life is where it should be.
Maybe I disabled an app that needs to be enabled or something. I don't feel like figuring out which one it is, so I just enabled all of them.

I mean when I first set up the phone I disabled the apps. I've been using the phone for a few days with the apps disabled, so I just re-enabled them this morning.

This seems counter-intuitive. Until a few more people report similar situations I'm reluctant to believe that it was one of the apps being enabled/disabled that caused and fixed the problem.

I personally disabled all the bloatware that was possible and I've had phenomenal battery life. Sounds like your phone just needs to go through those first couple charge cycles to get the battery going properly.

yeah mate, have to agree with the guys above. i disabled all the ATT crapware and haven't had any problems. sounds like you've got a wake lock somewhere. download CPU Spy from the market and search the forums for Better Battery Stats to find the culprit

I've got quite a few things disabled and I hit 34 hours on a single charge earlier today. Sadly I had to reboot so the uptime chart only shows 24 hours.

After seeing this I've re-enabled all of the HTC bloatware (facebook, twitter, etc.). I have a feeling that my crappy battery life may have something to do with HTC's Sense software somehow trying to interact (with their widgets and whatnot) with my disabled apps. If that doesn't change anything, I'll try to enable AT&T's bloatware too and see if that makes a difference.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​What I have right now out of Doze are "Bluetooth MIDI Service", "Bluetooth Share", the "Clock" app and two other Clock apps.
I am not sure how effective is the method listed below after the last update. Stay tuned.​​
Also I think the current version of Facebook Messenger is draining too much battery.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​Hello everyone,
when I bought my Zenfone 3 ZE520KL, I was amazed by it's battery life. I could easily get around 8 hours of SOT in a single charge with moderate usage. My device was running Android Marshmallow 6.0 out of the box, but performance wasn't as good. On Nougat, performance is much better and faster, also I used to get some lags and frozen screen, the capacitive keys also sometimes froze when I was charging my phone, but now I don't get issues like that as often as before. Interface is so much more appealing and I love it.
But what about battery life? I started getting around 5 hours of SOT.. which is still good, but not really close to 8 hours. I thought a lot about these 3 hours that were missing so I decided to start investigating. I wanted to share my findings with you so maybe you would know something that could help.
It's been two weeks since I have been testing out different things. The apps I used to do my research are:
Carat. What I love about this app is the process list. It shows exactly which apps and system processes are running in the background, so I can control them very easily.
Greenify. Thanks to the Carat app, I can see which apps continue running in the background, so I can use Greenify to hibernate them after I'm done using them. (Examples: Youtube, Snapchat etc.). Also I bought the Donation Package, and unlocked the other modes using adb commands (my device is not rooted).
BetterBatteryStats. This app is usually used to detect wakelocks. I limited the Google Calendar App from syncing so it doesn't use too much battery in the background. This app is paid in Google Play but you can get it for free from here.
What I did to get better battery life:
I excluded the services, that were always running in the process list from the Carat App from Doze. Apparently, the new Doze in Nougat gives us permission to optimize more system processes and services than before, which can backfire - Doze starts trying to kill processes that can't be killed, and this results in consuming more battery juice than saving it.
How to enter Doze settings and make the following changes:
Go to "Settings" > Select "Battery" > Tap on the three dots at the upper-right corner > Select "Battery Optimization" > Select "All Apps" > Find and tap on the Apps/Services/Processes I have listed below > Select "Do not optimize". The other apps and services should stay optimized.
The apps, processes and services that I removed from Doze are:
Android Services Library
Android System
ASUS Calling Screen
Bluetooth MIDI Service
Bluetooth Share
Camera
Clock
com.android.smspush
com.asus.keyboard
com.asus.shim
com.qti.qualcomm.datastatusnotification
com.qualcomm.qti.tetherservice
org.codeaurora.bluetooth
org.codeaurora.ims
com.qualcomm.qcrilsgtunnel
ICESound Service
Mobile Manager
MobileManagerService
System UI
Telecom Service
Telephony Service
ZenUI Keyboard
ZenUI Launcher
Some other apps that I'm using: Do It Later, Greenify, Messages, Nova Launcher, Timely, Weather.
Please do a full charge to 100% afterwards and check if the battery still drains as quickly as before. Your feedback will be greatly appreciated.
I am already starting to see improvement in my battery life. I was losing around 2% on Stand By and battery was draining fast when I was using the phone, but now I lost 0% on Stand By overnight and 10% for 1 hour of SOT (before this I was losing 10% for 30 min. of SOT). I am still trying to figure out which services exactly are causing the drain, when they are being optimized. Maybe the services, included in the Android System? (Check them from Settings > Battery > Android System > Included Packages). I deleted Facebook and Twitter apps and started using them from Chrome (almost the same thing, I quickly got used to that). Please check the updates below for more info and share your opinion or advice in the comments so we can all reach a better experience with this amazing smartphone.
Thank you for reading!
Update1: 6h30min SOT with 30% left (917mAh, 35%), but I will have to charge now. I have been messing with Doze a lot, maybe I'll get more clean results later. Progress has been made though, at least with my device.
Update2: Something interesting - my J-Score with the Carat app before and after starting this experiment: http://i.imgur.com/Q8u6HBD.jpg
Update3: There is a battery drain when making voice calls - 226mAh (7%) were lost because of 43 minutes long talk time.
Results were worse after testing with the second list removed, although there wasn't much draining with the screen on: SOT - 5h20min for 70% of battery (752mAh, 20%).
Update4: com.android.phone appears as a wakelock at BBS (Wakeups:8). Also 2h30 SOT for 30% used battery (100-70%~408 mAh). I'm updating the list and trying again.
Please note that my phone is updated to the latest firmware WW_Phone-14.2020.1703.28-20170410.
Update5: com.android.phone is still an active wakelock (Wakeups:14), but SOT is 2h34min for 30% used battery (100-70%~343mAh). At 30% battery left, SOT is almost 6hrs(28%~787mAh), Device Idle is at 10% (291mAh). The MobileManagerService is causing way too many wakelocks and is probably the reason for the high Device Idle battery usage.
Update6: MobileManagerService is no longer showing as a frequent wakelock. com.android.phone (Telephony Service - Wakeups:9) and com.google.android.apps.messaging are the most persistent wakelocks, other than that battery life is amazing at the moment. SOT is 2h45min for 30% used battery (100-70%~366mAh). I also had 27 min of talk time (4%~145mAh). At 30% left, I have 6h33min of SOT (32%~912mAh). Device Idle is again at 10% (292mAh). We are ready for the final test.
Update7: The results are quite interesting. After removing com.qti.qualcomm.telephonyservice from Doze, com.android.phone stopped appearing as a frequent wakelock at first, but now, at 70% it has 16 wakeups. SOT is 2h22min (100-70%~318mAh), so it's not better. I'm going to try a few more changes.
Update 8: I posted it as a reply here.
Update 9: I shouldn't have put Task Manager out of Doze, I get so much better battery life now. The update is ready, check it here.

Good post, thank you for investigating this, please let us know if you find more stuff or what exactly is responsible for it and an easy way of fixing.

Hello! Thank you for your reply. I'm so happy I could help others and myself with this thread, but I also need to know if you are also seeing any difference. Please check here regularly!
Also, I'm guessing that when you put your system processes and services in Doze, you also decrease their performance, which causes battery draining, as they try to run normally and do their work. Doze is trying to prevent them from doing that. This is my conclusion, but only results will show if I'm correct. If you own yourself a Zenfone 3, please feel free to report if you experience any changes using my method.
Thank you and have a nice day!

Hi, thank you for the post. I have a zenfone 3 here and will try your method.

I'm trying it on ze520kl with marschmallow, it seems working fine. :highfive:

Do you remove the first and second list from doze ? or ate testing with only the second list now?
Nice findings btw

thanks !

@Blackrose110 any news improvements after update3 ?

New update is released via OTA (~500MB).

Too early to say, also I got a weird wakelock, and lost 2% overnight. I lost the results (100-90%) after a restart. Now I'm going to update my phone and start again.
I had 8% used up on 43 minutes of SOT, and 2% lost on voice calls (100 and something mAh). I went to bed with 92%, I guess the other 2% were lost on that wakelock and the clock wakelock. These 2% were lost on equal intervals.
It's going to take a while, I'm just using my device normally. I don't have time to be on my phone all the time, also the battery is harder to drain now. At this point, I'm just trying to get better results.
Cheers!

I don't think it is a good ideea to change Doze settings for system services like com.qualcomm.* or telephony*.
In theory, these services should be compatible with operating system and they should work as designed. I would focus on third-party apps who doesn't work well on Nougat.
Anyway, is just an opinion and i'm looking forward for updates

Hello ci6i, I also agree with you, and that's why I excluded all of them from Doze when I first tried this out. At the moment, I removed only those system services, that run in the background all the time. My goal is to find the least amount of system services and processes, that are causing battery drain when the phone is in use.
I am not saying that you should do exactly what I did. It's best if you try out yourself on your own device what works and what doesn't.
I also have only excluded from Doze apps that I use daily. But everyone is using different apps and it depends only on the developers to update them.
You can download Carat for free from Google Play and check the process list, it's very useful. The app itself doesn't use any battery.
Good luck!

I agree with you and i really appreciate your work Yesterday I've installed Carat after i read your first post and today i did new OTA update and cleared cache partition. Let's see how it works in the next few days.

What should I do next, guys? Remove other com.qualcomm/com.android/com.asus services or remove just MobileManagerService from Doze? I'm thinking about the second one, I'm curious to see if ti makes any difference. I think the results from the first test were the best, and the MobileManagerService was out of Doze as far as I remember. Might as well try and see what happens.
It's a bit hard to drain the battery these days, so updates might not be fast. Patience is key!

Yeahh final test!! Looking forward to the result

Battery life considerably worse after update to 9.0

OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...

Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!

Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either

Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.

I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.

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.

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

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)
https://imgur.com/M9zO2hV
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.

General How I vastly improved my S22 Ultra battery life in 2 steps

Hey all,
I bought an S22 Ultra a few months ago and was disappointed with the battery life I got, even after I waited fo Adaptive battery to kick in. I expected a hell a lot more with a 4nm chip and more efficient LTPO Adaptive refresh display. So, I did some investigation and I think the main culprit it background services hogging battery. I tried out a few settings and finally found the following 2 steps to help me drastically improve my standby drain and battery life. Thought, I'd share them here, so anyone else who has terrible battery from the S22 series could try this out to improve their battery life.
Here is what I did;
1. In the Developer options, there's an option called "Suspend execution for cached apps". Please enable this! We all have to accept that Samsung devices have a lot of services running in background which hog the battery and all poorly optimized for efficiency. As some other posts have claimed this setting just shuts off all unnecessary nonsense running in the background. After enabling this setting, my standby drain is incredibly minimal (about 2% overnight, utit used to be 6% or more). I still get notifications from messenger apps (see next step).
2. In "Background usage limits", put all rarely used apps to Deep sleep or even just sleep. Here, make sure to put all your messenger apps to never sleeping to get notifications.
NOTE: I don't see any performance hit with the suspend cached app setting. Adaptive battery should actually do this (in a less obtrusive way) , but for some reason doesn't work as good this setting in disabling background usage. If anyone cares to explain this, I'm all ears

Yes. I have left it on. When I disabled it, I got slightly worse battery life. But, the game changer is suspending cached execution. I see immense difference after enabling it
One thing I don't understand is, in Android 12/13, if we put apps to Deep sleep and keep adaptive battery on, I don't know if this will affect the Deep sleep configuration

I am testing this right now, and after almost 1 day of ussage, i think that battery has improoved quite a bit.
18h 28min usage, out of that 4h SOT, and i have 37% left battery. , so thanks for this. One more thing that i did is, i turned off RAM plus. I think 12 GB of RAM is enough.

Hello, can someone tell me how to disable RAM plus? I want to test if this improves battery, but can't see an option to disable it, only to select how much RAM you want to assign. I'm in Android 12, still waiting the update. Many thanks.

I just turned it on, lets see what happens.

Tested it for a bout a week, battery is a bit better, but in some cases system UI gets unresponssive or totaly lags out. Would not recommend this option as it is not stable. Also in some calls people didnt hear me, so I had to repeat the call, than it would work fine.

Tried it for a few days and went back to the default setting. Phone performs better in default setting for me. Battery life was never an issue for me either.
