[GUIDE][CM9/CM10] Battery Optimization

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.

Re: [GUIDE][CM9] Battery Optimization
Finally, someone with a little bit of sense, even on the N4 I use most of those tips and get 2 days of battery with moderate use.

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.

Sudden battery drain (bad settings by accident) on Paranoid

Hey guys,
I'm running the Paranoid Android ROM. Since a few days I noticed a battery drop of maybe 70-75% (compared to 5-10% before) in flight mode without touching the phone once for about 9 hours.
A few days ago I took the phone out of my pocket and the screen was on and I "touched around" (notepad was opened, also contacts and my alarm clock). Do any settings in there strike you as a possible battery drainer?
In my battery stats, Android System is shown to be using like 75% percent of the battery. Now it's Google Play Services, for some reason (the play store is not turned on, neither maps, neither any sync option as far as i checked it).
I have WakeLock installed:
1013 1m 53s, x163:
--> AudioMix x163
Phone 1m 42s, x452:
--> RILJ x437
Android System, 1m 24s, x607:
--> Activity Manager Launch x233
--> AlarmManager x253
Those are the most striking. Does anything seem off to you?
Thank you very much in advance, I don't know what to do anymore!

I'm not sure if Wakelock does this automatically, but try manually disabling some selections to do with Play Services. I believe this is quite a common issue.
Try Settings > Privacy > Privacy Guard > Menu(3 dots top right of screen and enable "built in apps") > long press Google Play Services > Turn off Wake Up/Keep Awake if not already.
It may help, hope it does.

Unfortunately, paranoid Android doesnt seem to show the system apps (settings -> system -> "app permissions" (translated)). Under "app permissions" I can choose "keep active" (translated), I guess that's the original "Keep Awake". Under privacy the privacy-guard-option-area is missing, so I guess I found the equivalent menu item.
I'm trying the app WakeLock and over the night I didnt lose one percent of the battery! But I would rather like to have deep sleep without an extra app. How the hell could that happen, anyway...
Thanks for your help, I appreciate it!

Anyone else missing gmail notifications unless screen is on?

I have no power saving settings on like aggressive doze or close high powered apps.
Ill just let my 3T's screen turn off and send an email to my gmail account from my work email. I will not get a notification unless I turn on the screen.

Yes, I have this issue only with Gmail, Oxygen 4.0.2.

Same here.
It happens with WhatsApp as well but I hadn't had time to troubleshoot it.

Gmail/Inbox use normal priority notifications as opposed to high priority, therefore will never bypass Doze. For some odd reason however, selecting Do Not Optimize makes no difference. This issue is not specific to the 3T.

I have noticed this too with whatsapp i can't remember if it started happening on 4.0.2 or when i flashed a different kernel, probably 4.0.2 related

I have exactly the same issue ... mostly with gmail and possibly with other apps like Whatsapp (I need to use my phone more to be sure) but surely and deeply with gmail.
Sometimes I receive push notifications on my OnePlus3T (running OOS 4.0.2 and unrooted) flawlessly, sometimes it takes a delay from one minutes to several, sometimes I need to wake up my phone (with the Jedi move of waving my hand over the proximity sensor) and sometimes I need to open the gmail app and force the update with a slide.
I think I also notice a random delay for the notification even if the screen is on and the phone in use, which seems to exculpate the doze mode but I'm not 100% sure and it is much more rare.
This is really annoying to me as I didn't have this issue with my old Nexus 5 and which I don't have on my work iPhone. I try to convince myself that it is not a big deal but it's not easy ^^.
I tried to contact Google on this but they weren't helpful on that matter.

There a 120 pages post on the OnePlus forum about this issue on the OnePlus 3, even before OOS 4.
Can you tell me where is the "Do Not Optimize" option you're talking about (despite it is not working, strangely) thanks !

if you are ready to sacrifice a little bit of battery life, you can turn off Doze. You would need to do that in 2 places.
1. Settings -> Battery -> Three dots top right -> Aggressive doze and app hibernation -> Turn off
2. Settings -> About Phone -> Keep taping Build Number until phone marks you as a developer -> Go back one screen -> Developer Options -> Doze mode -> Turn off
I hope this helps.

Thanks for the tip.
I will give it a try but read on the OnePlus forum that it was not really a game changer.
I hope people working on Android know about this "feature" and will correct it soon if it has an impact on all Android N users !

I have that same issue.
Everything was working for me perfectly then all of sudden. Notification for Gmail Google plus and WhatsApp stops working no matter I am on mobile network or WiFi.
It work only when I open the app
I am on RR Rom

The easiest fix I found for my work email (Nine), which wasn't getting timely push notifications... was to just turn off battery optimization for this app. That made it perfect and instant notifications again. Presumably it uses more battery in this mode, but I still need it.

How exactly does one turn off optimization? I can't find that option. Thanks

It's kindof hidden:
Go to Settings-> Battery-> 3 dots in upper right
Then in Battery Optimization section, select 'All apps' from the pulldown selector at top.
Then find your app and change it to 'not optimized'

Yes it was kind of like an easter egg but I found it. Notifications are coming in on time so far I hope that's fixed the problem. Thank you

I dont find Gmail in the listed app?

In the Battery Menu/3 dots I don't have a Battery Optimisation Section but 2 settings (with my own translation from French to English, sorry about that) :
- apps hibernation & doze
- greedy application management
In the first option, there's a selector to activate or not the Apps hibernation & aggressive doze --> I disabled the option (and one can choose the app to optimize or not, but gmail is not on the list)
In the second option, I have a selector to allow to shutdown automatically "greedy" apps --> I disabled the option
However, in the Applications menu, while choosing the wheel then the Special Access Menu, there's an option for "Battery Optimisation" in which one can choose - one by one - the Apps that are optimised or not.
Anyway, for me, disabling the Doze mode in the Developper options seems to solve the problem with Gmail but i still have issues with delayed/lost notifications for other Apps (Twitter, Le Monde, ...).
And I'm running 4.0.3

That's weird, I do have Gmail listed in mine. Make sure you set it to show all apps.
Also, I haven't done anything unusual with Gmail, like converted it to a system app, for example. It was flashed as part of Gapps Micro.

FI, just posted a bug report on that issue : https://forums.oneplus.net/threads/random-delay-with-push-notificatio-ns.500958/

Samsung m51 idle battery drain issue

Attaching the screenshots of two night battery drain.
When,
Wifi off, mobile data off, nfc off, Bluetooth off, always on display off the battery drain is 16% overnight.
When airplane mode is on the battery drain overnight is 3 %.
Not able to point out what is draining the battery.
First 2 screenshots are related to 16% drain.
Next 2 screenshots are related to 3% drain.

Something similiar was reported with M30s ( when I used it ). Seems some Samsung software glitch.
Simply use airplane mode

I feel like after installing the november patch the battery performance has gone down a bit. Also the general performance also seems to have taken a hit in my opinion.

Improve M51 Battery backup do some settings to save more battery life and observe for next 1-2 days, it will give a noticeable difference.
1. Connection>more connections settings> disable

2. Location>improve accuracy >disable

B. Bluetooth scanning.
3. Device care>battery power mode>select "optimised" and "adaptive power saving".
And then click on "app power management >
And enable these 2 options.
A. Adaptive battery
B. Put Unused Apps to Sleep.
4. Long press on each app specially 3rd party app(LIKE FACEBOOK, YOUTUBE) and rarely used apps and also ON "GOOGLE APP" as well, then click on>app info> go to these 3 options below on by one
A. Mobile data> allow background data usage>off
B. Battery >allow background activity >off
C. Notification disable unnecessary notifications like promotional and unnecessary reminder notifications.
5. Go to settings> privacy > permission manager > location, and check which app have accessing your location all the time and if you not using that apps much, then deny access or set as " allowed only while in use"As unnecessary location access by 3rd party app causing battery drain.
6. Go to settings > Google > on device sharing> check which 3rd party apps present there for e.g. if you use paytm, paytm will shared data to show recommendation and suggestion which also cause battery drain
7. Go to settings > account and backup> account > check which app syncing automatically there, and if any app which not necessary to auto sync then click on it and "disable sync"
8. Go to settings >apps>search "weather">click on settings icon right side > change "auto refresh" settings as per your requirements and disable some unnecessary reminder. ( due to auto refresh it continuously consuming battery)
9. If you use Facebook frequently then disable "auto And if you are mostly uses mobile, on wifi connection then also disable "auto play videos" in YouTube.
10. Google >click on 3dot at right top corner>usage and diagnostics off this option.

Question [Origin OS Ocean] How to get push notification from various apps (like social and messaging)

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?
(Latest Origin firmware)

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
