Killing services

This is a pretty general question, but I couldn't find much on google about this. According to the task killers on the market, an app won't be able to stop a service like exchange or maps automatically (it can only kill the UI app). However, the exchange and map services have lots of alarms associated which increase my battery drain by at least a full %/hour. If I kill the services manually every time I use one of these apps then everything is fine. Does anyone have insight into whether an app or script called from tasker can accomplish this automatically?
FYI: I'm using the CM9 unofficial ROM.

You do not need to kill tasks. The system automatically purges non system apps. Just leave them be and always exit an app using the back button

"App killers" aren't recommended past Froyo and can even harm performance.
Under ICS, you can "Disable" many apps using the Manage apps off the main-screen menu. Titanium Backup can also "freeze" apps.
Many of the Google services get pretty "greedy" depending on your settings. That would be a good place to start for "core" services like those.
If that doesn't work, there is the sledgehammer approach of removing the apk from /system/app -- If you do that, watch your logcat to provide some confidence that you haven't disabled something that you need for another app to work.

Le sigh.. didn't even read my post. Also I'm pretty sure the back button thing is a myth.

Anyway I'm not trying to kill the "apps" themselves. They can sit paused in memory. I want to end their back-end services without uninstalling the app. The exchange service, like I said, will drain the battery with its unnecessary alarms even if I disable sync and turn the sync frequency to "never" and uncheck all the boxes when deciding what to sync. Google screwed up majorly with exchange, but when I kill the service manually using the method you describe then everything is fine and I can still boot up the app like normal to check my email manually. I just want to automate killing the service.

Unrelated to your OP but related to your post - on CM9 based ROM's - if you go into Settings > Developer Options - scroll to the bottom and select kill app back button. It works well.

I am also interested in a solution to this. I was hoping to find a widget that displays services, daemons or whatever you wanna call them, in plain text on my home screen, similar to rainmeter for windows. Then you just tap it to manage them. There has to be something similar around.

GPS Drain?

So, every time I use the GPS, it doesn't turn off even after I turn it off in the settings. I'd use GPS on a route and I'd turn off Google Maps, I've tried force closing Google Maps, turning off and on the Location, and many other things, but nothing has worked. The only thing I can do is restart the phone, but this is annoying to do each time, Here are some pictures :

This happens when I forget to restart the phone right away.

custom rom? and maybe a bit more info about your general setup. are you using a widget to tirn it ofg or are going to the main phone settings, gps to turn it off?

Stock, rooted, custom recovery. I use the Power Toggles to turn it on and off usually, but recently I have been going through Settings, Location to make sure it's all turned completely off, not just the GPS, but also all location. Then I look back at the Battery and see that the GPS time goes up a few seconds constantly, despite location being completely turned off and no Google Maps or anything else running in the background.

no maps running in the background? its taking 59% of the battery! your issue is probably google maps, not gps. look at your maps settings, maybe something. also, reboot. ive seen maps act like this before, for many. do you use greenify? something to look at as well.

Yup! ^^^
Use titanium backup to convert maps to a user app, then greenify it.

Update: This problem occurs with Waze as well. I force closed it, and Greenify'd it, and I still see the "GPS On" time continue to go up. I feel the GPS might be turned off but it still shows a big battery drain coming from Waze.

Turn off location services completely. Should stop it. If location is on....many apps could be using it. Maybe you have a rogue app spamming location services.
But maps and Waze will drop the battery fast while in use. After they hibernate... Its other apps using location.

I did that. Turned off all kinds of Location in the Settings Menu, no Wifi, no network tracking, just no Location. The GPS On time still goes on, so that's what's perplexing me. Perhaps I need to factory reset to see what's up.

Maybe. I've never heard of GPS running when location services is off. There's only one place to turn off location in settings, and if it off, it should be off. Strange.

if you go to location settings, press google location reporting, do you have google location reporting and location history off as well?

High battery usage - can anyone help?

Hi everyone,
I'm having some major issues with my s10e. It started draining the battery very quickly and it now needs to be charged 2-3 times a day with very little usage. I'm talking like 1 hour SOT usage. It's loosing over 5% of battery per hour just sitting on the table doing nothing. I turned off syncing, uninstalled some apps that could cause is, cleared cache and finally factory reset it. I even downgraded from android 11 to android 10 to see if that will make any difference. But no success. Still high battery drain. It sometimes gets a bit warm as well while not being used. Better battery stats reports high mmc0_detect activity. I've checked my wife's S10lite and she doesn't even have that kind of wake lock at all. I googled it and it's got something to do with memory card. However, the problem exists with several memory cards I checked as well as without one in the phone.
Samsung replaced the battery last week under the warranty but that did not help at all. I'm getting really frustrated with this phone now.
Does anyone know what could be the cause?
On the ss below you can see that it lost 12% in just 2 hours with 7min SOT. That's definitely not what it should be.

Turn off wifi. Disable all power management and see what it does.
Disable all cloud apps and FB, WhatsApp etc.*
Disable all Google, carrier and Samsung feedback.
Disable Google Firebase.
Turn off locations when not needed.
You'll toast that battery if you don't tone it down; don't charge past 80% for now to lessen the damage.
*try running in safe mode to see if it's a 3rd party app causing it.

How to disable google, carrier and samsung feedback?
How to disable firebase?

I've not had any issues for over a year of ownership. I've not installed any new apps or used the phone in any different way than I used to.
Thanks

I think mmc0 refers to your internal memory; my guess is that it doesn't work as it should or that it isn't connected properly.

Disable Google Backup Transport, Framework and Playstore/Google Play Services (enable as needed). Clear data on all the former except Playstore as needed. Clear System Logs at same time.
Reboots and factory resets are useless for this issue.
Use this Package Blocker*:
Home - Package Disabler
The only NON-root solution that let’s you disable any unwanted packages that come pre-installed / installed with your phone / tablet.

Use Karma Firewall (Playstore) to lock it down better.
* you can block all cloud junk, carrier updates and any bloatware as well. Some apks have dependencies so bare this in mind when blocking.

So with google play services disabled the battery drain is pretty much the same.
Also disabling google play services results in my phone constantly throwing notifications at me saying that some apps need it to work properly. Also without google play services I can't use Google Pay which is a no no for me.

That's what I managed to find out but I don't understand how would it not be connected properly? Besides, everything works fine, all apps, photos, music, it's all there and works on request.

Question Keyboard locking up

I'm having an issue on my a52 where the keyboard is hanging a lot. I installed g- keyboard and it's a bit better but also hangs.
Anyone else have this issue and know of a fix?

Clear the system cache.
System instability and lagging are a bad signs... the only warnings you may get before a crash.
Make sure your data is backed up.
Find the root cause, suspect malware as a possibility as well.
If you did an OS upgrade a factory reset is needed.

Thank you for the reply.
I just received the phone yesterday and went through setup. I did check for updates and there was an update available so I ran it which brought the phone up to the latest June security patch. This morning after reading your message I did a factory reset to see if that would help but the keyboard still hangs. It's like it just can't keep up with typing or something? Everything else seems to work perfectly fine it's just typing on the keyboard that seems to hang?
"System instability and lagging are a bad signs"
Do you mean to say that it's possibly defective?
I have the 8GB / 256GB model.
If I switch between Google keyboard and Samsung Keyboard it will work ok for a little bit but them it starts hanging again. Very strange behavior.
Sure would suck to have to send it back

This a new phone?
Is there carrier bloatware present?

New to me, open box, unlocked SM-A525F/DS. Doesn't appear to have carrier bloatware.

I don't know... my first inclination be to return it.
Check for updates including the Samsung Galaxy store and Playstore. Make sure it's not a 3rd party app causing it.
My S4+ do that crap sometimes and I think was internet connection related.
The native keyboard is one of the best, it's the only one I use.

Yeah, I would think that the native Samsung keyboard app would work flawlessly but for some reason it hangs much more than the G-Keyboard.
Like I said I did a factory reset it and only loaded a new google account so I could test it out fresh and it is still doing it. It doesn't do it when I first open the phone but then after using it a bit the keyboard hanging issue starts to happen.
When I google the problem I only came across someone having the issue on a A51
the software update page says that it is up to date: Current version : A525FXXS2AUE2 / A525FOJM2AUE1 / A525XXS2AUE2
Security patch evel: June 1, 2021

Crap... that sucks. It maybe a mobo issue or a corrupted flash. I say return it if you can.
Almost sounds like a memory leak... is the ram usage steadily climbing?

So I got back from a dentist appointment and had left the A52 at home and I go to test the Samsung and Google keyboards and now they are working perfectly fine, smooth as butter, and I can't make it hang/freeze anymore?!?!?!
New to Samsung, coming from my PH-1 with custom ROM.
Where would I check that ram usage?

Yay!
Power management can cause erratic device behavior, I never use it.
Activate Developer options. Also you can see ram usage in Samsung Device Care.

Interesting, I do have power management on, I will keep that in mind if it starts acting up again.
I now have developer options on and I checked Device care:

You need to weed out misbehaving apps one by one on a case by case basis.
3rd party apps that demand to run at startup deserve special attention.
Some apps like Brave browser continue to run in the background even after you close them. I finally ended up firewall blocking it when not in use to stop this behavior... nothing else worked.
Firewall blocking apps that don't need internet access also helps to move things along.

I do not have Brave browser on my A52? Was it a pre-installed app on yours that you can't uninstall?

Just an example. I keep it because of it's ad blocking ability plus no malware has ever breached it.

ok. Well it looks like power saving mode was already off. it must have reset to off when I did the factory reset. Under more battery settings there is a Adaptive battery setting which is on? Would this effect it?

Adaptive battery, kill it. That could induce this kind of behavior. Android manages its self well without it. Simply close out apps when done with them. This works well with most apps except for poorly coded ones like Brave
Go to running apps in Developer options to view some of what's eating up the house.
Sometimes cache apps like Brave are still running in the background even though it's not shown as a current running service. Killing it off the cache list will however shut it down.
I found it's easier to just close Brave then firewall block it until needed again
Hey, it could be worse... it could be an iphone

Thanks for you help! I just killed Adaptive battery. I found "Running services" , Im guessing it is what you mention? I do see a lot there: KLMS Agent, Video call effects, Samsung Pass, SmartThings, Bixby Voice, etc..... Samsung Keyboard and One Ui Home seem to be using the most memory.

Yay
Yeah a lot junk. I use Package Disabler and Karma Firewall as well as settings to knock it down.

Typically those apps use a lot of ram but not much battery or CPU cycles.

Holy cow thats a lot, I have very few running compared to yours!
Adaptive battery seems to have been slowing the phone down as everything now is much more snappy.

Question How can I stop battery drain on "screen off"?

I'm happy with the battery performance, but only when the screen is on. When I use the phone mostly with the screen on, I get good SOT(6-9 hours), but with the screen off, the battery consumption is terrible. How can I pull this down?

Probably a cloud app; try temporarily disabling Google play Services, Google backup is a dependency as is Playstore, Gmail. Some apps also need it to run. I enable it once or twice a day. Disabled saves 1+%@hr.
Trashware social media apps like fb, WhatsApp etc shouldn't be installed. It all adds up.
6 hours SOT with a 5002 mAh battery isn't good, 9 hrs is fair to poor. That said all Samsung's should be optimized for best performance.

Thanks for your opininon. Are you saying we shouldn't use Whatsapp? Is it real solution?

Unfortunately, because of SD 8 gen 1 limitations (probably worse on Exynos variant), about 6-7 hours SOT is best you're going to get on the S22 ultra.
Try the following guide here & see if it helps your battery life.

I have the Exynos version. My phone has a SOT of about 10 to 12 hours. Rooted and bebloated. I do have the brightness very low though.
Android 13.
OneUI 5.
Latest.
Lightly debloated.

That's interesting. I guess depends on what apps the phone is using during SOT.......
Mind sharing your battery usage breakdown screenshot?

Real as it gets. All social media apps should never be installed. Many should even be logged on to. WhatsApp track record is stunningly bad.
Lots of users means its got a huge bullseye on it even if they try to secure it, it will hacked again like the sun rises in the morning... for sure. Meanwhile phishing scams run under the radar and count on you screwing up. And many do.
You got to ask yourself one question,

No really. The problem is that all the apps developed by Meta (Facebook, Instagram, Whatsapp) are power hogs. Meta does not care if it chews up battery. The primary reason is that Meta is shoving ads in your face. Even when your screen is off, those apps are running in the background. Meta is not the only offender. There are plenty of other app developers that do the same thing.
Also, there are different "flavors" of Android. Each OEM implements it differently (even within the OEMs). This makes it less cost effective to customize their apps for each OEM. There is only one flavor of iOS and iPadOS, so it is much easier to tweak it for iPhones and iPads than it is for Android devices.

I understand. Thanks. I have another question. You said you turned off google play services. When I turn it off, notifications do not work and many applications do not work. How do you overcome this situation?

It doesn't effect any notifications for me that I use except Gmail. Most my apps run without it. I tend to shun those that do.
Some of the Samsung apps take the place of Google apps, no need to run both.
If killing Google play Services helps at night it's likely Google backup Transport running.

Hello, I have something to ask about. I need to know if there is any ability to store a system application variables usin adb. Imagine that I want to open my settings app and do something mabye a confirmation dialog will be shown in order to say something such as alert for something supposed that I did click on OK, i the normal case this alert will never be shown even if you clear the settings app data or clear the cash, is there any way to use adb to store the settings app data before opening it the if anything as the previous senario happened I can restore the settings app to the moment before clicking on the OK button or even before this alert has shown

Many apps that "need" Google play Services are Playstore pay apps. This can be circumvented by first allowing the app to activate, then firewall blocking their internet connection. Firewall block Playstore as well although it should be disabled except when needed.
If an app doesn't need internet access to function it should be firewall blocked anyway.
