Some of this advice is based upon our current understanding of bugs in CM9 and how to best workaround causes of battery drain until the developers are able to fix their causes. If you have suggestions for further improve this guide, please reply.
Power Saving Options
Google Talk is logged in by default.
You probably did not want this? Go into the Talk app, hit Menu button and Sign Out.
Turn off haptic feedback and touch sounds
By default the phone vibrates when you touch menu options or type on the onscreen keyboard. Vibration uses a lot of power. Sounds when you touch the screen also use a little power.
- Settings > Sound > scroll down to System
Dial pad touch tones - many users like it, others turn it off so it is silent when dialing the phone to avoid bothering other people.
Touch sounds - default touch sound is very subtle so many choose to keep it. You can save a little power if you turn it off
Screen lock sound - also subtle, I personally keep it.
Vibrate on touch - strongly recommend to turn this off if you want to maximize battery life.
- Settings > Language & input > Android keyboard > toggles to the right of it
Vibrate on keypress - turn this off to maximize battery.
Alternatively, you can make the vibration much smaller in Advanced settings near the bottom. Keypress vibration duration settings of 5ms is nice. It is a tiny reaction you can feel from pressing an onscreen keyboard button.
Turn off LED Notifications
- Settings > Display > Pulse notification light
Blinking LED notifications are nice. Unfortunately, the Epic CPU is unable to sleep while blinking the LED because it relies on software timers. For this reason, it is strongly recommended that you turn off LED notifications entirely if you wish to maximize battery life. As measured by CPU Spy, maximum CPU deep sleep can jump from 65% to over 95% with this option turned off. You can still hear the notification chime and vibration when you have an incoming message.
- Settings > Display > Pulse low battery light
You may also want to turn this off for the same reason. If you do not, the battery will drain even faster when the battery is already low.
Put Wifi to Sleep while phone is sleeping
- Settings > Wifi (touch the icon on the left) > Menu button > Advanced > Keep Wi-fi on during sleep
Strongly recommended to choose Only when plugged in. The behavior of this option is different from Gingerbread. Rather than turning off the wifi, CM9 instead seems to put it into a semi-sleep state. Data is turned off, but it can recover very quickly when needed. If you want Wifi to turn off entirely, Juice Defender Plus or Ultimate edition is capable of controlling Wifi sleep states while the screen is off. It is uncertain if Juice Defender disabled Wifi really uses less power than semi-sleeping Wifi as set by CM9.
No Signal? Use Airplane mode
- Settings > Battery > Cell standby
If your Time without signal is a high percentage, then your phone's radio is using extra power trying to find a cell tower that does not exist. If you are in rural areas with weak or no cell signal, your phone uses significantly more power as it tries to find a cell tower. Enable airplane mode in order to conserve your battery until you return to civilization.
Turn off Facebook Notifications and Background Data
In the Facebook app, hit Menu > Settings. Uncheck Notifications, and it also turns off background data refresh. This allows Facebook to fully close instead of always running in the background draining your battery and using some previous RAM.
If you want Facebook and its background service to die completely, use this procedure.
- Settings > Developer options > Kill app back button > Enable
From now on, when you are done using Facebook, hold down the Back button. This will completely kill Facebook until you run it again.
Turn off Data and Sync when you do not need it.
Different types of users
Why should your phone be busy while the screen is off?
Juice Defender - understanding the benefits and drawbacks
Reduce the number of applications that start automatically.
Apps you install will sometimes (and in most cases) have triggering events to start those applications in the background when certain events are triggered. In most cases, it is safe to disable that app from automatically triggering and instead launch that app when you want it as you normally would. By reducing the starting of applications, I have found that I also save battery because, well, my phone is doing less work and less work equals more battery.
I have seen some apps autostart even though you have disabled autostart events for that app (unclear yet why that's happening). If you find that is the case, and you want to stop it from running, try moving that app to the SD card using a program such as DroidSail along with disabling events. Why? Apps on SD cards at present do not receive the on_boot_complete event. Please note, this may break some functionality such as widgets.
In order to decide what to disable, you need to understand how you will use the app and whether you need it to run in the background. You can use an app such as Autostarts to control the startup on Android (At the writing of this it costs $1.03 USD).
When selecting apps to disable autostarting in Autostarts, stay clear of ones highlighted in Yellow as they are system apps.
- Look for these key events:
After Startup
Connectivity Changed
Other events can also be disabled but remember, by disabling events that start apps, you can be breaking the functionality that the app gives you. For example, disabling ‘after startup’ on an app such as AdAway will render the webserver that runs as part of that application to not run on boot. Be smart, but disable what makes sense.
If something doesn’t work right and you are not sure what you disabled for that app, simply uninstall it and reinstall it.
Stop syncing things that you don’t use regularly.
You can always manually sync them when you need them.
Access the menu here: Menu -> System Settings -> Accounts and Sync
For example, I use Gmail, Google Contacts, Google Calendar, and Google Browser regularly so I let that sync. I disable Google Currents, Google Docs, and Google Chrome Beta because I rarely use them. When I want to use them (once every couple weeks), I start the app and sync them manually.

Here it seems to do miracles, lots of persistent services that refuse to close (e.g Poweramp in my case) are automatically hibernated with Greenify.
I have tried everything I can find in the settings but apps that are excluded from "lock screen cleanup" are still closed.
I have locked them in the recent apps panel, I allow them to use background data, data saver is disabled, but regardless, the apps are always killed by locking the screen. I thought this aggressive battery behavior was supposed to be fixed in EMUI 5.
I am suffering with the same problem on my P10 where background processes are killed after locking the screen despite having set them not to close the app and its service are killed sometimes when the screen locks. Android 7.0 EMUI 5.1 VTR-L29C432B151
Is there any solution for this? - I use a Zoiper for SIP calls and it is being stopped and I am missing calls
Turning off the close option in Lock screen clean up did not make any difference but, I did see in settings -> Battery -> "Settings Gear" an option to 'Close excessively power-intensive apps' and turned it off - but not tested it long enough to see if it fixes the problem.
----- did not work
Yes, same here - missing notification from Ring doorbell, missing updates from Tile and Life360 and Withings watch not synchronising automatically... Annoying behaviour.
Ok, tried something today and so far apps aren't closing - even after a few hours. Open Settings | Apps and click the settings at the bottom. Tap Special Access | Ignore battery optimisation... Select the apps you want to keep alive by switching to "Allowed".
I also have Battery | Lockscreen Cleanup disabled for all apps and the "Close excessively power-intensive apps" option unchecked.

When I do that I only get a list of a few Apps, the ones I want to keep running are not included - Is there a way to add them to this list?
Tap the arrow to show Allowed or All.
Sorry for the false alarm folks. Overnight all apps were closed again, regardless of the "Ignore policy" setting...

At first I thought it was working, but eventually all the apps that I needed running always were terminated and had to be restarted manually.
This bug is so incredibly annoying, is it by chance fixed in VTR-L29C432B164 - I am getting so fed up with this phone killing services that I rely on to be running all the time - I don't care if they consume more power, I just need them to keep running.
I have the same issue on P10 Lite WAS-LX1AC423B171 this is the latest firmware I could install. Driving me mental!!!!
So I think just about every game on my oneplus 7 pro triggers a built in thing called gaming mode. Is it possible to create a profile that begins when that gaming mode starts and ends when that gaming mode ends. In this way I adjust things like volume levels and screen on time along with what the gaming mode does. And once for all of them instead of a profile for every game.
My guess is there is a custom setting that defines the status of the gaming mode. That's only a guess since I don't have a One plus.
You could use the native tasker settings -> custom setting action to see if you can identify what changes when the game mode turns on. Tapping the magnifying icon [emoji361] will bring up an assistant. Once you identify the setting, it can be used in a profile context (system -> custom setting).
From some online reading, I also think that the games that trigger game mode are entered in a list by a user. You could use an app context with each of those games selected so your profile activates whenever the game is in the foreground.
Hitting the gear/cog icon when the profile is selected will bring up settings for the profile. One of those settings is a toggle for restoring settings when the profile exits. In the case of an app trigger, when a different app is in the foreground, the settings made in your entry task will revert.

Upon starting a game that starts game mode the only thing that this method finds is a screen brightness change. when used from state. And nothing when used from event. Strange because if a game is triggering a system setting or something there should be something for tasker to see get triggered so a profile could tie into running while it is active. Much like a profile that would trigger upon phone charging for example and end when not plugged in to charge any more. Any other idea how i can identify what is triggered (for game mode on/off) to set a profile to run along with it?

Yes in game mode you add whatever games you want to trigger the mode. On my LG G4 I had a profile for each game but the profiles were problematic. Some of them would turn on and off while the game was still running. If I can have a profile that runs when game mode is active and ends when game mode is not then I would completely avoid having a new profile for every game.
I was suggesting using the custom setting action in a task to determine the setting. Then use that information in a profile to monitor it.
You can attempt to manually identify the custom setting (if that's what is controlling game mode). See here.
I'm thinking the mode reverts as soon as you leave the game to return to Tasker, so the built in assistant may not catch the change. Grabbing the settings via ADB and running a diff on the before and after may be the only way to go.
Otherwise, someone in the device forums might have insight how this mode is monitored.
As far as the app trigger approach, sometimes you can stabilize the task by putting a wait action at the start of an exit task and then stop the exit task of the calling profile is active (%PACTIVE).
Thanks for the reply with a method to identify the setting. Assuming that it is a setting. Using the custom setting action is a task when tapping on the icon it says to toggle the setting and return to tasker to find out what it is the results ended the same as attempting to use it by the other ways. It returned nothing or brightness found. I'll have to give the method in the link a try and see what happens. Will report back, might be a couple days.
I finally was able to identify the setting for making the profile, thanks much for the help.
Like the title say, I'm in trouble getting the notification of any app I install : I disabled vivo.pem as suggested in one other thread and allow notofication per single app (that were turned off before) and last disabled the background battery optimization for those apps.
No luck after all, as nothing show up when I send whatsapp mess e.g.
Any ideas?

I had to use the uninstall command on vivo.pem to get my notifications to work, disable didn't help me on the latest firmware.
Also, check the app permissions, hold down app, info, app permissions.
Turn off (remove permissions if app isn't used)
Single permission settings (turn all on the switches), you can also review permissions
Go back 2 screens and select notifications, select all sliders and then check your desired app notification is going out via priority display.
Finally go to settings, battery, background power consumption management, and change the setting for the app you want to not sleep by choosing high background power usage.
So annoying, I know, too many settings and easy to forget one
Good luck!

Thanks for the time spent in the long answer; however still no notifications on the tested app (whatsaap) with all the reccomended settings.
Is since 2015 I think that I don't have a chinese firmware phone and the things have changed, in fact, before, was enough to install play store and all the notification were received without further settings.

Hey Guys,
i also did every setting as told and my Notification for especially WhatsApp isn't working at all.
Sometimes it does, but then all of a sudden it just refreshes when I open the App itself.
I even put it down in the Bar with the 5 Main Apps, in hope those would be refreshed or kept alive in the Background.
Not sure anyway what you mean with uninstalling vivo.pem.
Suckz kind of, because apart from that it really is a great Phone... aside from Android Auto not working.

You have to plug in phone on computerand run ADB command to uninstall vivo.pem.
Vivo.pem is a system that aggressively shut down apps to save battery power, to much shut downs and notifications stop working.
Check the thread "Origin Os initail review" on here and you will find out how to do it. Takes only 10 minutes

After doing the uninstalling did it stop the issue?
I uninstalled, rather than disabled, their power saving vivo.pem, ensured all my apps had priority permissions for notifications, disabled battery saving, and added them to 'autostart' in their respective permissions, and I get proper notifications for all the social media and messaging apps. The only small glitch come with Google Messages which won't display notifications in system wide dark mode. You can get around that by enabling the 'chat bubbles' option in Google Messages settings as they do work in dark mode.
Notifications are not the only issue , i cannot select Mock gps location app in Developer Mode ...
I press on the app i want to use ,but nothing happend , the app is not selected .
Anyone noticed that too ?
Thanks
There is no need to uninstall vivo.pem, I think. Just some few steps:
1. Go to recent apps and lock it.
2. Settings -> Apps & permissions -> App manager -> WhatsApp -> Permissions -> Single permission settings -> Autostart and Startup enabled.
3. Settings -> Battery -> Background power consumption management -> WhatsApp -> Select high background power usage.
4. Settings -> Battery -> More settings -> Disable Sleep mode.
Works fine for me.
Do you use Whatssup? after the latest OS update it cannot connect to linked devices
Hi,
I have set up the display timeout option with the settings below but it doesn't seem to work. I am using an oppo phone on Android 12.
Create a new task. Select the “+” button. Select “Display” followed by “Display timeout” Select the time span you want to set and then save. Now select “Profile” and click “+” and then “Applications” Mark the applications for which you want to activate this Tasker profile.
Then I open the app but after 15 seconds the screen turns off which is the default device screen timeout.
Is there no way to override this? Maybe get tasker to somehow keep interacting with the screen to keep it on?
I've tried this on a few apps and have got two different messages..
One says screen will stay on for 15 seconds which is the system screen time out.
Other says tasker will keep screen on but still times out after 15 seconds.
Really want this to work as some apps like games I don't want timing out after 15 seconds and I don't want to increase the system time to couple of mins for every app.
Hi,
I have the same problem on my OPPO A74 with Android 11 ((ColorOS Version V11.1). It seems impossible to create a task to change the screen time out; not in connection with a profile, shortcut or widget. The amazing thing, though - when you test the task in Tasker it works perfectly fine.
Media Volume, I think, also doesn't work. Other app connected profiles like autorotate or display brightness work well. I wanted to test more but I can't find the time.
I really miss the screen timeout though. It drains the battery too much to set it constantly to 15 minutes or so, but for some apps less simply is annoying.
The developer created some apk to help with some OPPO related problems, unfortunately, it didn't help with this one (sorry, I can't remember exactly what it was).
A kind of workaround: Once you've activated the Developer Options an your phone you can enable "Keep screen on while charging". When you need longer screen time, just plug into a charger.
But using a Tasker Profile would be much nicer.
Hope somebody knows a better trick.
Not sure if following could help your situation ( only for your gaming situation )
Create a new Profile, choose > apps > add your game apps in it. click left top arrow when finisning add gaming apps.
Tasker will pops-up task list > creat new task > Screen > Turn on.
** when above profile is complete , click the task when you are still in Profile list. Hold the task, it should pops-up with option exit task. Choose this as exit task.
Play around to see if this profile is working when gaming apps in foreground, screen never turn off.
EDIT: Try first not move the task as exit task. ( make the task as normal entry task )

Thanks for your reply.
Creating the profile is not the problem. It just seems that Tasker cannot change the system's setting. As mentioned, there is no problem when you create a profile allowing the screen to rotate using a speciffic app (and others as well ) I have no idea, why it does not work for the screen timeout.

I use no screen timeout, I use "screen turn on" in your situation as my op., enough I've not tried it on my Samsung A71.

"Display / turn on" works fine when I want the screen to turn on with a notification. But the screen turns dark after the system timeout has passed. I've also tried "Display / Stay On / with Wireless, AC or USB Power" and with the AutoInput Plugin "Screen Off Or On: Turn On / Timeout Never" but the screen always turns dark.
Those Profiles always worked on my other Smartphones (LG -D405, LG-K10 and Moto G6). I believe, it's the ColorOs that's causing the trouble.

below is a task ONLY FOR ROOTED DEVICE., no harm to try even if your's not root.
New task , run shell command , in the command input
there is a button 'use root' , check that button also.
settings put system screen_off_timeout 200000
** 200000 I'm not sure sure equals to how many second., just give it a try and if you get a longer screen on time from your issue it means it is working.
also, make another separate task, search for 'custom setting'. look up from there I thingk it is in system something about screen timeout.
EDIT: run shell command task suggest you run it manually., than see if it works. if not, restart device to check if it requires a restart in order to accept new timeout settings.

I feel like I'm in Star Trek - "To boldly go, where no one has gone before" XD
When I try your suggestion, I only receive the message that my device isn't rooted.
Btw, for some tasks it is necessary to enable the Write Secure Setting Permission (f.e. Set Assistant), where xou have to setup ADB on your PC. Would such a procedure be registered by the phone as rooting? Anyway, I don't think I would dare to do something I know so little of.
Another solution I was thinking of, is it possible to create a tasker quick tile/ quick setting to change the system screen timeout.
So instead of having it change for certain apps which isn't working at the moment.
Maybe if we can change it from the system so will be for all apps. You can create two separate quick tiles to toggle between different screen timeout settings.
The newest version of Tasker (6.0.9) comes with Tasky.
Tasky offers the possibility to activate premade profiles. One of them is "Keep Display Awake For Apps". And that one works with my OPPO Phone.
I also tried "Auto-Mute Apps", another profile I couldn't get working. It also works fine.
To switch between Tasker and Tasky you just have to click on the "Three-Dots-Button" in the right top corner. It's not like switching apps but using different user interfaces.
Good luck!
- Sorry to say, but this seems to work for some apps and not for others. But at least sometimes it does work.
Thanks for replying back to this thread to inform me. I tried it and it works for the app I was trying to make it work for which is good! Makes it so much easier now.
