Hi,
We all knew that we should not use task killer to kill apps, because when we hit the back button, the app will not active anymore ... but it will still occupy some memory (RAM).
When Android OS needs more RAM it will remove in-active apps to free some.
Related article: http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/ (GOOD READ)
We should not panic when we see a huge list of apps when we start task killer.
Ok, got it there ...
Now, I installed this app called Quick System Info (FREE):
http://www.cyrket.com/p/android/org.uguess.android.sysinfo/
Which you can use to see what kind of processes are still running or apps that are still occupying RAM. It could show you the amount of RAM and CPU resources that are being used by each app.
So, I went to the Quick System Info -> Processes, hit the "menu" button -> Preferences and set like this:
- Update Speed = Low
- Show Memory Usage [checked]
- Show CPU Usage [checked]
- Sort by = CPU Usage
- Direction = Descending
Go back and watch ...
Surprisingly, I saw "Market" app is eating 1% CPU resources once in a while ... again and again ...
Hey, I thought it (Market app) is suspended in the background? I don't have it active, I pressed the back button when I finished with it.
Why is it eating 1% CPU from now an then in the background?
Obviously, this will drain battery power for something that I don't need.
Any thought?
I am now wondering if I install other kind of process monitoring app, and see if the suspended Quick System Info is also eating CPU resources
Why should we not use task killers? I`ve used them on android for the last year otherwise like you say background tasks use resources slowing up the system.
Obviously dont close any system important apps but I`m always closing down background apps that I no longer require.
1% every now and again? I really wouldn't worry about that to be perfectly honest. The impact on battery life will be incredibly small, so much so I doubt you'd even notice if you weren't watching it like a hawk.
By far the biggest drain on battery life remains all of the wireless stuff (wifi, bluetooth and 3G internet) followed closely by the screen itself. Turn those off when not in use and the miniscule drain of suspended tasks won't be an issue.
I'm sure if Google thought suspended tasks would be an important factor in battery drain they would've designed it differently to start with.

It does every minute or so, and so far I found only this app (Market).
I just found out this morning before went to work, so I don't have time to inspect more.
Too bad I cannot see CPU TIME (the amount of time the process took 100% of cpu resources).

that 1% would be it occasionally checking in with the market to see if any updates have been released for the programs you have installed, so that it can give you a notification when the update is released.
i would imagine that is what it is anyway.
and yes, 1% every so often is negligible, and if you killed just that process, i doubt you would notice any difference.

I am not sure about this..
Have you noticed that you will get a notification if there is an update to application that is installed in your phone?
I think the marketplace doesn't have a push notification yet. So it periodically will check whether there is any update to the installed application.
Allright, that might be it ... the Market is checking for apps aupdate.
And most probably 1% is not much (I don't know how to measure this and translate it to battery life time). 1% every minute ... hmmm
1 hour of 1% cpu per minute = X % of battery life.
If we have N processes?
N = email check, weather check, friendstream check, RSS check, whatnot check
I`ll give you an example why I use a task killer.
Sometimes I use an app that goes online every few minutes and notifies me of any updates. I can 100% be certain this app even when in the background uses enough cpu to cause the phone to slowdown. Dont ask me why, maybe bad programming but this is the exact reason why I need a task killer to get rid of it.
Once its gone the phone is fine again. it happends on a few apps I own, so when I finish with them, I kill them.
I wouldnt recommend a task killer that kills everything, you just need to be selective.
That is a perfect example for using task killer
What I wrote in the first post is about using task killer to just kill apps without knowing anything.
In the past, I just select all and KILL ... Then the HTC Sense got reloaded
I was scared it could corrupt my phone ... lol.

Yes thats a bit extreme killing everything.
I`ve also used startup auditor in the past. That stops some apps loading at startup , for example footprints, never use it so I kill it before it gets a chance to load up. Have to be careful what you limit though as some tasks are used by others.
That Startup Auditor is interesting, does it work as expected?
Or you encountered some quirks or issues with it?
Yeah, I don't quite like with the way Android startup (or HTC?), for example: FM radio ... it also started automatically after reboot.

Seems to work fine, not sure what help it is though hehe, in terms of speed/memory savings. I stop the radio , bluetooth,google talk and footprints. But I also use it to start some apps automatically.
I found this list of what you can/can`t disable. You can still run them after startup, just they wont load automatically when you start the phone.

Battery Save Like RandomKing
I find myself regularly repeating many of these suggestions on many threads to many different people on how to extend your battery life. When not in use, my phone loses at most only 1-2% battery per hour! So I'm making one thread in the Epic forums dedicated to maximizing battery life while trying to explain why these steps will work. Some battery improvements come at the cost of performance or lack of certain services. This must be distinctly understood, or nothing wonderful can come of these steps.
Step 1: Brightness & Battery
Let's face it. Our Android phone screens are huge. This feature is the largest, and completely unavoidable battery-drain. The only way to limit it is to not use the screen... ergo... not use your phone. But that clearly makes no sense, so how to limit that drain? Well, a good step is to turn down your screen's brightness to the lowest you can read clearly, don't hurt your eyes! For night-time use, there's an app that can turn the brightness down even lower called Screen Filter(Thanks to iModMM for the find!). Also, choose a nice dark background, something in the black color range. For all phones, the darker the color, the less brightness used, less power consumed! But for our Epic's Super Amoled screen, specifically, a black pixel is technically an "off" pixel. That's right, every black pixel on your screen is a part of your screen not being powered, since the Super Amoled does not need backlighting. Blackle is also a good alternative to the standard Google site for a black themed search engine, though it doesn't seem to be mobile optimized. Also, lock your screen with that nice little button on the top right side of your phone. Don't wait for it to lock itself! As far as the battery itself goes, charging to 100% can be tricky. The moment that led turns blue, your phone has generally reached 100%, but it will generally trickle charge between 97 and 100 after that. A good way to charge to 100 percent is to use an external charger, which generally come with 1 or 2 spare batteries for about $20. This way, the moment your battery dies, shut down, and pop a fresh one in.
Step 2: Using a Custom Rom
At this point, there are many Epic 4G custom roms out, and if you're in this forum, you've likely rooted or are trying to root. Well I will not go into rooting directions here. Take a look at one and see how it fare's out-of-the-box for you. If you choose to use my customized rom, you will find a task manager with a preset ignore list, ready to use as a one-tap app-closing widget; as well as the service-freezing patch mentioned below in Step 8 ready for execution through a terminal, and my entire setup(among many other mods, apps, and tweaks tested for the greatest battery performance). These are just roms I've used myself to great results. Many others exist. Updated 7/6:
RandomKing's Customized Rom
2.2.1 EC05 v.1 Plus [Journaled w/Genocide 1.0] [Screenshots]
SyndicateFrozen Rom
2.2.1 EC05 v.1.2
Bonsai Rom
2.2.1 EC05 v.4.1.1 Not Supported on XDA. Sorry.
Midnight Rom
2.2.1 EC05 v.5.3
Step 3: Disable Unnecessary Services
First and foremost, disable all location services, wifi and gps based. This will affect certain apps like weather apps, you'll simply have to deal with static locations. Next, disable data sync. Contacts will not synchronize with Gmail while this is off. You will have to enable it sporadically. The Gmail app also will not function while this is off, I recommend using the email app and simply adjusting the refresh interval. You can always manually check your own email . Likewise, you may put your phone into airplane mode altogether if you don't plan to use it for an extended period of time, such as school, work, swim meet, movies, or on an airplane.
Step 4: Task Killers and JuiceDefender
First, let's get JuiceDefender out of the way. It's a neat app, and in certain ways, effective. However, it's own effectiveness comes with certain contradictions. It disables nearly all signals, which will include, for example, Google Voice. In my experience, this app hindered certain other services, and if anything may have drawn further on my battery. My recommendation is to stay away from it. Now onto Task Killers, they are good, and they are evil. Let me explain. Many of us may find issues closing all the apps we open, and sometimes forget we left something open. A task killer can easily ensure that you've closed all of your programs. Now onto the bad. Task killers can try to kill certain system services. This is generally BAD. Certain services shouldn't be killed, and others can't be killed, and the ongoing battle only further drains your battery while trying to kill services that AREN'T actually bad. So on that note, the worst part of task killers is AUTO-KILL. Disable it! Kill it! Kill it with FIRE! I use Advanced or Adao Task Killer, with no auto-kill. It is one of the only widgets I use, and I simply tap it before I lock my phone each time.
Step 5: Widgets
If you don't need them, don't use them. Almost all widgets make continuous unnecessary calls to the Android system, and this can be a huge battery draw. Even simple widgets. Through all my testing, there's only 2 widgets I have approved thus far: Advanced Task Killer, Power Control. Other disapproved widgets: Pandora, Winamp, Weather(ALL OF THEM), etc.
Step 6: SetCpu, Voltage Control, and Over/Underclocking
As with much of this thread, this is opinionated and empirical theories. Through my testing, Overclocking is unnecessary, and guaranteed to draw on the battery. Most of these roms come from fantastic devs and are, by default, blazingly fast. Overclocking is completely redundant in my opinion, and I'm generally all about speed. Underclocking/undervolting may preserve more battery, but my opinion on the matter is similar to my feeling on widgets. If you don't need it, don't do it. If you feel the need to use these apps, a generally accepted setting for battery preservation is to undervolt to 800 max. and 100 min. (if your phone can handle it, some may experience wake-locks, raise min. to 200) on conservative governor, adjusting your profiles for when the phone is locked, unlocked and etc.
Step 7: Unnecessary Apps
Free apps are great, aren't they? But how many have you gathered, just because they're free? Now how many of those don't you use, but regularly draw on your phone regardless. There's an easy way to roughly check. Open your settings. Now go to Applications. Manage Applications. Take a look at which are running that you have not opened. Using a task killer prior, and waiting a couple minutes to see what re-opens may be a good way to check which apps are continuously running in the background and evaluate if they can be removed.
Facebook --- Notorious for running in the background. Disabling notifications may help.
Latitude --- Largest offender of location service usage. Neat app. Huge battery hog.
QIK/Fring --- Any video chatter really. If you don't use them, remove or disable them.
Browser --- Large ram usage. Try Dolphin Mini or Miren.
Step 8: Freeze Services
Using Titanium Backup Pro, MyBackup Pro, or Bloat Freezer (yes, non-free apps) freeze any of the following services:
sns --- (Will disable sns)
snsaccount --- (Will disable Facebook contact integration)
drm --- (May affect media programs like mediahub)
drmcontent --- (May affect media programs like mediahub)
systemupdater --- (Best disabled if on custom rom)
Enter the following commands into the Android Terminal to manually freeze the above services:
Code:
su
pm disable com.sec.android.providers.drm
pm disable com.sec.android.app.sns
pm disable com.samsung
Simply enter the previous commands into the Android Terminal while substituting "enable" for "disable" to manually defrost these.
If you would like a shortcut for this method, check out the patch in This Thread Also Included In RandomKing's Rom..
Step 9: Journaling
Journaling... some love it, some hate it. The fact remains, journaling enables extra write cycles. While this will prevent data loss, it also means more cpu usage. It follows that battery should last longer with journaling disabled. You can use chris41g's mod HERE to turn Journaling on/off at will.
Step 10: Turn it Off and Spend Time With Loved Ones
That's right. You're obsessing with your phone. Leave it be. Do something meaningful and memorable. Have fun with life! This is just a phone.
More coming as it comes to me! Including mods, apps, etc. aimed at improving battery life. Feel free to leave your own suggestions or questions! If this guide and it's features have helped you in anyway, leave THANKS so I know whether or not to keep up on it!
Y is this in q&a?

has anyone noticed an effect on the phone's ability to sleep when you manually reorder the apps alphabetically in the app drawer? I kept having problems and factory reset 2x. Now I did find 3 troublesome apps that although not apparently running in the background, kept my phone from sleeping simply by being installed. I also stopped ordering my apps, deleted the troublesome apps and now it seems my phone is working correctly. I wonder if that (editing the default order) could also prevent the phone from sleeping? Any thoughts?

I'm non rooted stock EC05. I used to use EDIT in the app drawer to rearrange my apps in alphabetical order (they don't arrange themselves automatically this way after rebooting). I had noticed in spare parts that my phone was never sleeping and killing my battery. I did a factory reset and it worked as advertised. I slowly added apps back until I found two that seem to prevent my phone from sleeping so I uninstalled them. Phone worked fine for a while but then started acting up again. I repeated the procedure, leaving only the apps my wife's phone had (hers always sleeps like a baby), but then my phone started up again. Tried another reset but this time decided to leave the apps in the order they put themselves and so far so good...wondering if that was doing something or if it is an app update that goes bonkers?

Hmm. If you can't narrow it down to a certain app, I'm not totally sure what it could be. Have you tried clearing the data/cache of Twlauncher? You could try a launcher like LauncherPro, you don't have to be rooted to use a different one.
No but if the problem comes back up I will try some of those...these are the 3 apps that when loaded caused problems: NIV Bible, Document Scanner, [I now have relacement apps for each of these now] and most recently Espn Score Center, but my wife had all of thse but the doc scanner and had no problems
i would check in spare parts to see which apps may be holding a partial wake lock. for me the facebook app was not letting my phone sleep until i disable all of its notifications.

Likewise. This is why I removed facebook altogether. The new mobile site has proven to be pretty useful now.

Yeah I found the same thing...but I would log out of Facebook too. Also the problem reappeared after a factory reset and I had not gone into Facebook. Are you saying that even if you don't log in, it can stop your phone from sleeping? My phone started doing it again a few days ago for no apparent reason, and I was able to stop that behavior by: finding and moving 2 apps from the phone to SD card (I thought I had gotten all of them), clearing any cache from different apps, and rebooting.

That wouldn't tell me anything when I had the problem. The only thing was Android System....and....the phone wouldn't sleep even if in airplane mode! Which meant it had to be a process or app doing it all the time. I had never thought to clear cache, but I wonder why doing that works? Also there's a menu option in Spare Parts about Button Behavior which leads you to believe you can make the phone sleep but the menu says "only available in Ver 1.5". I've checked the market and can't find a ver 1.5 Spare Parts...

I believe it means android 1.5, because that says "End Button Behavior", and no new phones have Call and End buttons on them. Because the "Fancy Screen Rotation" says 1.5 only also.

I think you mean "Now go to Applications. Running Services." Going to Manage Applications will show all non-system applications and not tell you what is currently running, AFAICT.
Or am I mistaken?

Sounds to me like a system process may be the cause rather than any particular application. For me also I had issues early on with the SNS service forcing itself to restart continually and being a battery drain. It usually takes a force stop on that service followed by clearing data in the sns app and rebooting to fix. Don't know if that will work for you, but hope it helps.

My tips you can add:
1. I always, no matter what, always have brightness on lowest setting! If you have a hard time seeing in sun, than do auto, but turn off when don't need to, I have on low 24/7. Then at night, I have this app called screen filter which lets you lower brightness then default setting(good on eyes).
2. I always have auto-sync off. If you want emails etc. configure with ur preferences. And most of the time background data. But with background data off, you don't have access to market and have to enable for use. Don't get notifications. Lately, haven't been getting WhatsApp messages. This is optional.
3. In wifi settings, network notification turned off. Haptic feedback and all vibration disabled. Sounds on key clicks or anything disabled. Auto rotate screen off. No window animations. Screen timeout, 15 seconds. Keyboard timeout, 3 seconds. In location, use wireless networks and gps satellites unchecked.
4. No live wallpaper! No bright colors! I use a black background for wallpaper!! Try to go a little dark, not bright, stay away from white! Id recommened, the full black wallpaper. Also on ur homescreen, avoid widgets! Especially ones that use live web feed like, facebook, scorecenter. These are battery suckers!
5. I delete all apps I do not use! Stock and user. Download titanium backup to fix this issue. I freeze, system updates, swype, drm content, drm content launcher, sns, snsaccount. I uninstall the stock browser, use dolphin!! I also uninstall, all sprint bloatware, my files, gmail, email, talk, news and weather. Uninstall all stock and user apps you don't use! Check spare parts to see what runs in the background that you don't use. Another thing to add, I uninstall swype and android keyboard and use better keyboard gingebread edition 8.
6. Disable refresh interval in facebook, do it manually when you are going to use it!
7. Use setcpu. Undervolt to 800max and 100min on conservative governor. Set profiles, when phone is locked and etc.
8. Now lets talk about juicedefender and task killers. Juice defender will work and is a good app! BUT: if ur a person like me, I text a lot in whatsapp and when u lock screen it disables data, so u wont get texts. Download it, take a look at it, try it out. I recommend using agressive mode. Now lets talk about task killers. Personally, I think they dont work at all, and actually waste battery then save it. I just would say don't use one, and use samsungs stock task killer(actually works!)
9. Use a custom rom and kernel. Always be up to date on updates. I usually use, SRF and midNight. All about preference.
10. Extended battery FTW!!! Buy a seidio extened battery! May cost some money, but will greatly increase battery!!! Or get a cheap asian knockoff on ebay.
11. Disable data and put phone into airplane mode when it wont be in use for a period of time. Like at school or work. I usually keep data off during school. You will see a difference with data on and off.
12. Always keep wifi, bluetooth, gps, 4g off when not in use. They will drain battery crazy!!! Wifi will search for networks constantly, same basic thing with gps and bluetooth.
13. Also do full charges!! At night shut off phone and let it charge for a good 8 hours. Then in morning, turn on still plugged in. The charging indicator will be red, leave it alone till its blue. Go get dressed and eat some breakfast lol. Then when you come back it should be blue. And when on boot, let it finish media scanning, don't interrupt it!!
I can guarentee if you follow my tips, you will see a significant increase in battery life!
These are my tips!! I will add more if I can remember some more!
Typed this all on my Epic!!
Hi all,
I seem to get this issue with pretty much every single Android Device I've owned in the last 8 years, particularly Samsung ones, and that's the good old "Android System" battery drain.
I have tried everything over the years, except rooting the device, but nothing has ever worked as a permanent fix.
I have tried:
- resetting device
- clearing cache
- restarting phone
- Shutting down background tasks
- Low battery usage location settings
- Deleting apps
- a million other things
But one way or another, Android System will eventually make its way back to the top of my battery usage stats.
I've come to the conclusion that it's the OS itself that's badly coded which causes this.
Has anyone, anyone, ever figured out a way to get on top of Android System battery drain?

I'm not sure this effects that, but while setting up phone from a factory reset etc, do you Uncheck the fields that pop up such as analytics, wifi scanning (even while off) and all the other ones ?
I uncheck all the crap i can. It's possible if you leave those checked that could be the culprit a bunch of services running in bckgrd....

I'm not sure this effects that, but while setting up phone from a factory reset etc, do you Uncheck the fields that pop up such as analytics, wifi scanning (even while off) and all the other ones ?
I uncheck all the crap i can. It's possible if you leave those checked that could be the culprit a bunch of services running in bckgrd....

Yep I un-ckeck all of those fields. Makes zero difference overall (I have tried both ways).

That sucks, could it be due to social media apps syncing constantly? Sorry I'm out of ideas....

Ibreak, maybe the problem is caused by apps sending reports and analytics via google services, samsung related stuff always sends analytics, even if you do not facebook, the damned thing is always lurking and consuming resources, google app and chrome also are resources-hoarders, I use ccswe to disable all useless firebase, crash, analytics, ad listeners, campaign trackers, components and some boot listeners within many apps

Hi all,
I seem to get this issue with pretty much every single Android Device I've owned in the last 8 years, particularly Samsung ones, and that's the good old "Android System" battery drain.
I have tried everything over the years, except rooting the device, but nothing has ever worked as a permanent fix.
I have tried:
- resetting device
- clearing cache
- restarting phone
- Shutting down background tasks
- Low battery usage location settings
- Deleting apps
- a million other things
But one way or another, Android System will eventually make its way back to the top of my battery usage stats.
I've come to the conclusion that it's the OS itself that's badly coded which causes this.
Has anyone, anyone, ever figured out a way to get on top of Android System battery drain?

Enable Developer option
then go Settings» Developer options» running services
Here you should see a bunch of services running. A number of them should fall under Android System, close all related to Android System (it is ok to do so)
Then under Google Play services close all (well two of those services are persistent so they will auto start back in a couple seconds, lockscreeen service and Google location service), nothing you can do about this other than to disable Google play services which would then cause a lot of apps to cry like pandora, samsung internet browser, play store, YouTube etc.
Then go settings» apps» 3 dots at upper-right hand corner» show system apps» android system» battery» disable background activity
On each restart Android system background activity will be automatically enabled so just disable it on each restart.
The thing is it could be a number of apps or services that is causing the issue through Android system but a good indicator of which app might be causing your issue is to check Android system memory which is right below background activity, there it should show which app is accessing the memory through it the most. Disable that app or clean its cache/data.

It's in the same place you'd find background activity, but instead of going to battery, go to memory.
settings» apps» 3 dots at upper-right hand corner» show system apps» android system» memory
At the top above average memory usage you should see the app.
I would recommend using a package disabler (ccswe from the play store or package disabler pro from their website)
You can disable a lot of things but DO NOT disable
boot agent (could lock your phone in bootloop)
Android system (could hand your phone on boot up)
One UI (unless you have a different launcher installed and enabled)
IMS is important too
There's one more I can't remember right now, but you get the idea.
If you're not too sure if something can get disabled with no harsh side effects then just post the question
settings» apps» 3 dots at upper-right hand corner» show system apps» android system» mobile data
Shows a list of all the apps that have access to the network through Android system, disable the the ones you're sure you're not using or will use. That should shorten the list of potential battery drainer.
Thanks again.
It just shows an app called "face" under Android System memory. I assume that's for face unlock.
Be careful with disabling OneUI, because it will also disable the task manager and you'll got a really ugly one instead.

Yeah that's for face unlock. I used to use it but since the fingerprint scanner update it has been working really well with my screen protector so I don't really need it anymore so I have it disabled.
If you don't use face.
How i use my phone to maximize my battery is simple. Things I don't use or need I keep them disabled, some I simply disable until I need them like the play store or galaxy store etc. Every other day or so I would check those apps to see if there is an update I might want to install.

I only use the fingerprint sensor, but it's still shows (only) Face there. Any idea?
There's really no fix to Android System drain, it's especially worse when you're on mobile data.
I am testing a faulty app that it's being faulty during deep sleep, therefore to fasten testing I would need an app which can force the phone to enter deep sleep mode immediately.
Any idea?
Macrodroid or Tasker maybe

Try disabling all power management apps ie all the toggles in Device Care are toggled off except fast charging.
Do not enable sleep for any; Developer options>stand by apps, all buckets should show as active if not power management is active.
Close apps when done with them especially ones like Brave.
The phone will automatically go into a deep sleep state at screen off unless a 3rd party apk is misbehaving.
On my 10+ running on Pie this is how it runs best and gets the best battery life.
Goggle Play Services, Gmail, Playstore, Google Backup Transport, Google Framework and Samsung cloud backup are prime offenders*.
Disable these and all Google, Samsung, carrier and apk feedback. I use Karma Firewall to find rogue apks and lock the phone down as well as a package blocker.
I also use Battery Tracker from the Galaxy Store.
Nominal battery usage is 7-10%@hour heavy usage like vids and surfing. Off screen usage with AOD on is 1%@hour.
*enable when and as needed
Try Naptime and what blackhawk says!

You'll need to play with it; what works with my configuration may not work for others.
These are my current observations. My stock AT&T 10+ variant is heavy modified and watched over. As I intend to continue to use the current Pie firmware, I continue to tweak it.
What I've observed though over the last year to my dismay is any power management interferes with functionality sometimes randomly and unpredictably. It actually ends up increasing battery usage within a few days although initially it may seem to improve it.
Apparently it causes system conflicts.
I have no power management active other than the screen is set to "optimize" in Device Care and even Device Care is package blocked then unless I wish to use it to clear the cache (which the factory load version does very well).
I toggle Google Play Services/Gmail on as needed and a few other battery hogs. Point is I know their status; no random shutdowns or apk failures... and the best battery life I've ever seen on this device.
You need to go explore, find the resource hogs one by one and find a way to tone them down.
All the shotgun get it done power management apks failed miserably for myself multiple times....
Android runs very well by its self once your rein in a couple problem apks.
Many times the factory loaded versions run better then their updated versions. Gmail, Gmaps, Device Care... may or may not be true on your load; trust nothing!

When I go into standby mode in developers options each app has 3 options. Frequent, rate, working set. What should I put them on?
Also what exactly does standby mode do? Is it manually disabling that app while not in use or only when you close it? As far as closing the apps, will closing them via the recent apps screen suffice or do I need to force close them?
And my last question is what do you mean by disabling an app such as play services?

It shows the app's bucket state when power management is enabled.
Your power management is enabled... and likely wasting battery even though it's suppose to do the opposite. If power management is disabled as I suggested, all buckets are locked to active.
Right now I have GPS enabled; I disable Device Health Services com as it was constantly accessing the internet.
Usually closing the app is all that's needed.
Use Karma Firewall and Battery Tracker to help ferret out bad apps.
Depending on your model, OS/firmware load, 3rd party apks and settings configuration your system may respond differently.
I have heavily modified them on this 10+ Pie variant; it's an ongoing process. I have around 88 apks packaged disabled as well.
Androids wuv to be played with...
Is there a way to prevent an app from ever being killed? I have 2 examples:
1) Fitbit app (background sync service, specifically) - when this stops running, some features on my watch quit working until I launch the app and sync manually.
2) Battery monitor app - I've tried AccuBattery (my preferred app), GSam, and BBS, but they all get killed and restart, and therefore give inaccurate information. BBS doesn't die as often as the others, but I don't like it as well. All 3 have persistent notifications, so I can tell when they last restarted.
I've set Battery Optimization to "Don't Optimize" for all of these. I've tried turning off all 3 of the settings under Advanced Optimization (probably unnecessary, no noticeable difference). I've also Locked each of these from recent apps. Are there any other settings I'm missing that could prevent an app from being killed? Possibly something new to Android 11? Fitbit and AccuBattery worked fine on my previous OP7P with Android 10.

I have try to to go to developer mode and go to standby application. go inside and set the app you want to always on to active and remember still set battery to don't Optimize and locked the app. Do not click the clear all button.

Interesting, I haven't seen that before. Thanks for introducing me to something new. All of the apps in question are currently grayed out and say Exempted, so they shouldn't ever be put into standby.
Disable all power management*, Android does fine without it. Address any remaining power hogs individually on a case by case basis.
Power management will cause erratic behavior and can even increase battery usage even after its lame "adjustment" period.
To check if it is fully disabled go to Developer options>Standby apps, all buckets should show to be in their active state (and can't be manually assigned), if not power management is enabled.
Make sure allow background usage isn't disabled on the apps you want to run.
*yeah turn all those optimizing toggles OFF.
Only fast charging should be toggled on if you use it.

How does one disable all power management? I don't see any sort of global switch for that. Turning it off entirely seems drastic, but I agree that power management is generally more trouble than it's worth.
I did verify that the apps in question are allowed to run in the background and use unlimited data.

It seems like you're setting up right. Check the Stand by apps status.
When you first load Accubattery it gives an option to disable task killing in settings, Pro version.
Uninstalling then reinstalling it sometimes works for me; clearing its data does not. I was getting the same error message until I just reinstalled it
Just don't take Accubattery too seriously... it's useful up to a point.
I'm on Pie. Google really screwed up 10 and especially 11... so yeah it could something new as Google insists on changing things even if they're already nearly perfect
If that fails check with Accubattery for guidance with 11. They are responsive to emails.
They may also be punching out an update.
