Battery Optimization list empty - Huawei Mate 9 Questions & Answers

Trying to ignore battery optimization for certain apps to allow push notifications but that list is empty and there doesn't appear to be any other way to add apps into it. I just recently reinstalled everything and of course disabled all the bloat with TB. Perhaps one of those bloat apps is responsible for this list. Any ideas?

I was able to track it down myself. The app is called 'Phone Manager'. Once defrosted, the apps once again show up in the battery optimization list. Hope it helps someone.

Poco X3 notifications work not good, quick...

I expect when I get a mail, a messenger message or whatsapp message a quick notification from the phone.
But that doesn't work... although I have put them out of battery save and always on....
Sometimes the notifcation comes, sometimes it doesn't.....
Have you the same problems? and is there a solution?
My phone is on battery saver all the time because I don't want unnecessary notifications from built in MIUI apps.
Even still all my notifications of the apps I use arrive on time (WhatsApp etc).
Check the settings of each individual app and ensure they aren't being killed or denied access. (I know you stated that you kept them on always on so I assume you have tried everything but here's just some generic advice.)
1: Settings * Manage Apps * MIUI Battery Saver.
2: Settings * Special App Access * Battery Optimization. (Type special in the settings search box) add the apps you use frequently there.
Disclaimer : What you're experiencing isn't normal behavior. Even though I have removed all my social apps from the "Special App Acces - Battery" section... I still get my WhatsApp notifications on time. My phone is on battery saver even if it's on 100%.
Is your phone disconnecting from network after screen off? Is cache being cleared after screen off? Check in security app (battery section).
I know I'm not of help, but I just want to know what you've tried and what you haven't because it's not mentioned in the post.

Optimise the battery on most apps and not getting some notifications ie Gmail so take it this is one of the side affects
Yep, stuff that runs in the background always eat battery. Especially Google apps.

Goggle play Services, Playstore, Google backup Transport and Framework are prime offenders.
The former two I kept disabled unless I need them. The latter two are package blocked.
Sync is turned off. Gmaps is kept firewall blocked unless needed otherwise it constantly is running in the background.

Optimization can eat battery and cause erratic behavior. Developer options>Standby apps, all buckets should show as active. Otherwise power management is active and it will cause trouble.
Dependencies... disabling some apps can cause seemingly unpredictable consequences and higher battery consumption. Goggle play Services has lots of dependencies but killing it saves battery. Turning off location helps too.
Turn off all carrier, manufacturer and app feedback.
Disable OTA updates; only update if proven to be worthwhile. Most updates harm the usability and provide little improvement. If the phone is running fast, stable and fulfilling its mission leave it be. Most carrier Android phones need to be optimized or they will run like pigs. Updates generally just complicate the optimization process.
Each Android and user are unique requiring different solutions. Play with it.
With Google you're not the customer, you're the product... the less Gookill, the better.

Was looking at this but what do you mean by 'all buckets'?
Some of the apps are on WORKIng_SET /ACTIVE or RARE and a few on FREQUENT
Anything to do on these to save battery
Also I have Dont Keep Activities ticked but even when I close the apps its still running and press clear all

*These are the buckets. Google terminology not mine. More Google bloatware.
If you can't change their run state there then power management is disable... as is best.
Simple close apps when done with them.
If they continue to cause trouble try limiting background battery and/or data usage.
Ditch the really bad actors if can't get them to behave.
Power management apps will cause nothing but trouble and eat battery. Android manages its self well without this junk with well written apps.

Google_C2DM wakelock

Hi
I'm on a stock Samsung Note 10+ 5G. I normally disable unused apps with Tasker and only load them as I need them, my primary aim to reduce battery drain. I wanted to see how good Android 12 was at controlling apps battery usage so I've enable all my apps, and put them into the following states:
Mobile Data - I've turned "Allow background data usage" to OFF
Under the battery section, each app is Restricted
I've removed from "Optimise battery usage" section, so they are being battery optimised
Under Developer Options, Standby Apps, I have put each app into Restricted mode
Most apps are behaving fine, but I'm getting quite a few apps over time using battery. When I check under GSAM, all of them have the same wakelock which is Google_C2DM. The apps typically are not active (i.e. when I check in the app manager, "Force Stop" is greyed out) and they are listed as "Manually Disabled". I've tried killing the apps, clearing cache on the apps and the phone, restarting etc but cannot get them to entirely stop battery usage. Is there a solution for this and any idea why its the same Google_C2DM wakelock?
thanks
I myself am investigating YouTube app battery usage and that component is also listed at the top in GSAM.

Question Sleeping apps management

Is there any way to manage sleeping apps so that when app is still on recent apps list, it will be a "never sleeping" app so it never goes to sleep. Is this possible with tasker or some other way?
What I'm trying to achieve here is:
I have some app listed as deep sleeping app, since I might not need it for a week and have no reason for it to ever run in background to waste any battery or spam notifications.
Then I might use the app to look for something --> switch to like browser to check something from there and when I switch back to previous application it's been killed and loads itself open from start which is slower and might lose some unsaved progress in the app.
I would really like to have it so app that isn't removed from recent apps list doesn't get killed and put back to sleep. Then when I do remove it from recents, it could be handled the default way to make it go sleep.
Can tasker handle these kind of situations like checking the recent apps --> if app X is on the list set it to never sleeping apps --> if app is removed from the recent apps set it to deep sleeping apps. Or some other similar way to control the sleeping/never sleeping apps.
Thanks

Question How to prevent apps from auto starting at boot

Hello,
All is in the topic, I've got an app that starts automatically when my phone is powered on.
It is Aircall, an app I use for passing and receiving calls at work.
I would like this app not to start automatically each time I power on the phone.
Is there a setting for disabling some apps to autostart ? Or an app you can advise ?
Thanks for your help.
Check the app's preferences to see if there are options.
In the Android settings, go to Apps > See All > (your app. eg Air Call) > App battery usage and set it to 'restricted.' This will greatly restrict an app's ability to do many things in the background.
Other than that, you'd have to root your device to get any more control over the app using something like Servicely (Google Play Store), My Android Tools (apkmirror.com), Permission Manager X (fdroid), AppOppsX (fdroid), or Blocker (fdroid) to control the app's broadcast receivers. Apps can choose to respond to various phone states such as when a boot is completed, when network connectivity changes, power is connected/disconnected, etc. It can take some aggressive action to fully prevent an app from always running.
If you're just annoyed by a notification icon in your notification area you can always disable that app's notification so it doesn't appear.
I have tried all of these things to control apps but if apps use a lot of various broadcast receivers they will find ways to keep running. You may find stopping it to have unintended consequences. It being a work app, I'd consider simply disabling the app's notificaiton if it has a persistent notifcation or something. The next step would be to restrict the app as in 2. The most aggressive thing is to root and tinker with its broadcast receivers.
Hello jawz101,
Thank you very much for this very complete answer.
All your precise instructions are very interesting.
I'll have a look at all these solutions.
Thanks again.
I am not sure about straight forward solution. But I would like to use Greenify app. Add apps to it once and run it once everytime you restart your phone.
