Hello to everyone.
I know that there are some similar threads in this forum, but no one is strictly related to the CM9 alpha IML74K.
I know as well that this could be part of the CM9 user discussion thread, but I'd like to share the best settings to get a good battery life with our S2 in a clean thread.
So, please:
no trolls, no dumb questions.
Just share your own experience (with a battery screenshot should be better).
Thanks a lot.
Here we go:
Developer options:
Debug usb off
Allow mock locations off
Force GPU rendering off
Windows animation scale off
Transition animation scale off
Don't keep activities on
Background process limit on
Kill app back button on
Display:
Automatic brightness off (I'm using Brightness Level widget)
Black wallpaper (search for solid black.png from wikipedia)
Sleep after 1 minute of inactivity.
Pulse notification light off.
Trebuchet options:
Scroll wallpaper off
Sync settings:
Google account
Sync calendar on
Sync Contacts on
Sync Gmail on
Whattsapp account:
Sync Contacts on
Sound Settings:
Touch sounds off
Screen lock sounds off
Vibrate on touch off
Location services:
Google's location service on
Location & Google search on
(Gps satellites on only when using Sygic or Maps)
Date and time:
Automatic date & time off
Automatic time zone off
CyanogenMod Settings app v1.0:
Interface Settings/Expanded view widget
Toggle 2G/3G checked
Toggle Mobile data checked
For a quick switch to 2G mode and save more battery.
Testing "twek levels and filtering" in automatic backlight settings.
With Titanium Backup:
Frozen all live wallpapers, tts services and uninstalled Gtalk and mail.
P.S. Be careful, you need debug usb on when using Titanium Backup
Data on all the day. I turn it off when I go to bed.
Wireless on when I'm home and need to use dropbox or download a big file from my Gmail account.
I'm using CM9 01062012 (I know, there's a new one, but I've reached a very stable daily rom, no FC, no random reboots, fast and smooth).
Modem XXKL1
Now my battery lasts two days.
Well, when my girlfriend tells me stories about her life, it lasts one day and a half.
Important:
I've uninstalled Facebook app which was causing a battery drain. I'm using the mobile web page instead and I've to tell that it is faster.
Other apps installed:
Twitter, Maps, Sygic, Whattsapp, Beatiful widgets (with manual weather update), Xda premium, ...
2012-01-14 Added CyanogenMod Settings Apk v1.0 (from SGS forums)
How to install:
Download it to your internal SD card
Enter into Recovery mode;
Wipe cache;
Advanced settings, wipe dalvik cache;
Flash zip from Sdcard,
Choose CMSettings.zip and flash it.
Reboot system
2011-01-18 Update:
I've been trying few modems and I've found the best one for me: (Vodafone Spain, data on almost all the time, good signal quality, great battery life)
NEKD5 Modem Zip package.
Flash from recovery. Follow cmsettings instructions.
Nice post. Going to try some your suggestions.
I'm sure loads of other xdaers are going find this useful too.
So many posts in the cm9 discussion thread about battery life and how to achieve optimum performance good to have a thread about it.
Big props

I also agree on removing the Facebook app ATM its killing of battery life.
We have similar settings besides using Facebook let me see if things improve tmr

Apparently its a bug. It makes the OS look like its working over time but actually it won't be. Its somewhere in the cm discussion thread if you want to see the posts about it. As far as aware its not fixed yet with any of the builds.

The same here. But I've noticed that using Fastreboot app, it seems to kill/restart stuck apps/processes.
Anyway, rebooting the system before the night helps a lot.
Unless you're not a modern vampire...
Agree with others - excellent thread. There seem to be so many battery challenges with CM9 that a separate thread will lessen clutter in the discussion thread.
I've tried a number of your settings and have also flashed the KL1 modem. I had high hopes for KP4 at first, but it seems to have slipped back into old habits!
Has anyone looked into the FB-app? Why its causing battery problems?

The app and the process are still running after you close them.
I have tried to logout, but it's still there. I think the process keeps going for notifications and photo uploading.
I've tried to kill it, but it comes back after few seconds.
Finally I gave up and used the mobile web page.

But that isn't related to CM9, i had the same issues on gingerbread.
Yes, sir.
I knew it.
But it seems to me that Facebook app is eating more battery on ICS.
Checked my battery info and found out FB app percentage was 15% in 6 hours and I've used it just to read few messages. Then I've logged out.
I could be wrong, but I think it needs an update to control battery drain.
Indeed. I'll bet there are a host of apps that will need subtle tweaks and optimisations for ICS. Another reason not to expect too much from CM9 in terms of performance as yet...although access to kernal sources is obviously the big one!
CM settings
Trying right now CyanogenMod Settings app.
Flashable zip from recovery. The apk goes to /system.
It comes from GTi9000 forum and as I can see, it works perfectly on my S2.
It doesn't have so many options, but few are very important.
Let's have a look...
I'd be very interested on your feedback on this app.
On a different subject, I seem to have my battery back behaving reasonably well again with KP1 modem. In my tons of testing it seems like Nova Launcher - as much as I like it - is a significant contributor to my battery drain issues.
This could be because I have installed a bunch more stuff on Nova than I have with Trebuchet, so my next tactic is to gradually reintroduce some of my favourite widgets to Trebuchet to see if one of them suddenly starts killing my battery.
On the down side it may mean that I can't use one of my widgets for a while but on the plus side it may eliminate Nova as a battery drain meaning that I can go back to using it.
Have you tried FBM for facebook?
Basically the same look as the facebook app. But supposedly a lot cleaner!

As I said before, don't expect a very useful app. It's the 1.0 version, and hopefully it will be a great app. But for now I've tried only some settings in the automatic backlight and modified the notification power widget.
At the moment, that's all we have. Anyway, give it a try, if you'd like.
Screenshots added in the first post.
Anyone able to disable button's backlight? Its still on even though i set it to "0" in the custom settings..
Another thing,is it possible to the haptic feedback tweaks like in cm7 settings?
Back from some modem testings, I'd like to say that NEKD5 has surprised me.
Never loosing data at all, best battery life and no problem with sms and sync.
Here you've got it.

Thanks in advance!
I've had fantastic results since I updated to 4.1.2.
I've done a fair bit of tweaking to get the results, but it's worth the effort.
Here's my advice.
Factory reset first. (Vital)
Turn off Google Now
Turn off Google location updating and history in Google maps
Disable all Samsung Apps you don't use. (This will be a massive list of useless apps and services)
Use a mostly black wallpaper
That's it.
Below in the screenshots are the results of this tweaking.
Please keep in mind, I've been reading books on my phone with moon+ reader. I use a white text on black background and mainly at night so low brightness. Hence the crazy long screen on time.
However I still sent numerous txts, browsed, used gmail, streamed music etc etc...and had two days of standby.
Screen on auto brightness, standard battery.
Insane. This is by far the best battery life I've ever had from an Android device...and I've had many going back to the G1.
I'd thoroughly recommended trying the tips.
Have a search around and you'll find a full page with all the Samsung apps you can disable...there are a hell of a lot of them.
Give it a go.

link ? thanks
My experience is similar, as I've done the same. I'd say that stock 4.1.2 (LL5) is about as close to perfect as it can be.
Which 4.1.2 rom are you using? I can only get a maximum of 6 hours screen time on my stock ELKC rom
and this is also on stock kernel?
LL5 with stock kernel and a full wipe. Lots of Samsung bloat frozen and removed.
More details please:
-Rom???
-2G or 3G???
-Wifi all time???
-Power saver mode on???

I use stock ROM odexed. I have sync off most of the time and I sync manually about once an hour or maybe once every two hours, depending on my schedule. Never use power saver, and I keep data toggled off when I don't need it, and I use Wifi in my office (and data only when out) so I think that helps. I don't run any widgets other than the stock calendar widget, and gnotes (and Google search, but I have Now turned off), no live wallpapers, Facebook or any of that crap. Just a dark (stars) wallpaper. I can get huge amount of time out of my battery that way, even with a good amount of screen time. I have around 80 apps installed, but keep the system running lean. I don't use any task managers or memory killers, and I rarely reboot. Maybe once every 3-4 days.

On 4.1.1, with Perseus kernel, auto sync and mobile data on all the time, I get even better battery life. Which is why I'm reluctant to update and start over, as the phone more operates perfectly for me.
There is a list of safe to remove apps in the Themes & Apps sections, it's a sticky thread even.

Just wanted to add that on ELL4 I'm suddenly getting fantastic battery life - I was having loads of random reboot problems (many times an hour at one point, unusable), then it all went away for some reason after lots of fiddling, and since then I'm on 27 hours without a charge, and still 35% left - that's with everything turned on still, no change in my usage; wifi all the time, Google Now, loads of accounts syncing including Latitude location, email syncing every 15 mins, some music and browsing usage, etc
Before, I'd get around 16 hours of this normal usage before the battery was getting ready for a charge. Weird, but I'm not complaining!
Well with ELL4 everythink stock rooted with enyxos abuse, and frozen samsung apps, i can barely get 6 hours screen on ..
I text friends, and use whatsapp over Data network(2g) (no wifi) and SYNC is off
Will i get 9h screen on with ELL5 ?
Edit : And yes i wiped cache / data before flash ELL4 via Odin
I still hold the record XD

Hey guys, I'm getting this weird problem lately.. Some, of the apps (that came to my notice) are not refreshing periodically.
For instance, I am not getting any new whatsapp messages, when i wan't to receive new msgs, i need to manually kill the app. Then restarting whatsapp, would deliver all new whatsapp messages
At first i thought this was a glitch in whatsapp, but then i observed my call logs, it still displays that i received a call about a couple of minutes, whereas actually its over an hour. To see the actual time, i need to kill it from recent apps and launch it again..
I searched, but unfortunately din-d not find anyone with similar problem, so decided to start it here..
I'm on 4.2.2 Stock ROM with Franco's Kernel 3.4 Milestone 2.
Its seriously annoying me..
Any help would be much much appreciated.. :fingers-crossed:
Are you running any of the following?
Greenify
SnapDragon Battery Guru
etc?
Juice defender?

Me also face same issue some times with whats app. Using snapdragon guru. But I have set option in the guru app for whatsapp that to refresh when it wants. I guess the culprit is idea network. I dnt kill apps they deliver mag after some time a bit delayed.

Hi all,
So here is my question...
I've been having horrible battery drain and have not yet put my finger on what is causing it.
I'm thinking it could be facebook/linkedin/other apps on my phone.
Is there any reason to install the APK version when a mobile web version exists?
I see the web version being a good choice as it won't be an app installed but rather just visiting a web page.
Any thoughts?
get better battery stats and that should let you see whats causing the drain....or look in settings>battery and see whats running there as well. the apk is there for convieniance and thats about it. the constant updates and radios being on will kill your battery cause the phone is consistently looking for new information. its really all user preference but to me bookmarking the site is just as simple as having the app. you just may not get the update that your friend you dont talk to is eating a taco and taco bell as fast.

It appears greenofy does a lot of what autostarts does. I use autostarts for all apps and disable most everything (for instance facebook with an app is installed/uninstalled etc).
Having said that, after wiping my phone yesterday and doing a fresh install of TriForce 3.1 with Agat 5.1 I've noticied a significant INCREASE in up time.
I only installed a few normal google apps. Linkedin/Facebook I'm using the web version. I got 21 hours out of my S4 with 2 hours of screen on.
When I have my phone configured "normal" i've got close to 90 apps installed.
I'm going to run a "bone stock" from for a few more days to see how the battery life is (i know you have to give the kernal a few days to burn in).
I just wish my phone could last a lot longer before dying.
try ktoonz kernel.......they have alot of preset kernel settings to help you get the most out of your battery and still maintain performance in the ktoonz store. i normally run 1 day+ with around 3 hrs 45mins screen time......and my screen time is usually gaming (psp emulation)and tweaking differant settings or downloading movies music etc.... so its pretty heavy usage...
Hello, since Oreo update the most of the s8 users facing battery drain.. personally mine needs 2 times to charge it on the day.. I am using messenger, Instagram, Facebook.. I know these apps are Killers for the battery but on nougat didn't face that problem. Also I have greenify to freeze the most of the apps, titanium backup.. a custom kernel with a Governor that promising battery life, but it has a lot of lag.. also the gps etc are off ! Let's find a way to fix that problem .. I don't know when or if Sammy will release update to fix it.
Atleast I didnt faced battery drain and easily get day of usage, sometimes 2 days. And yes, i'm using a lot of facebook, messenger, browsing internet, using camera and everything seems ok for me

What modifications have you done on your phone ?
I usually charge my phone twice a day since nexus 5, anyway you can use the lite version of messenger, skype and for the rare use apps.
For Facebook I personally unistall the app, but a good way to fix it is by downloading "Facebook less crap" (search on xda) then using RomToolBox pro and disabling all facebook startup, and the final touch greenify.
Same for the other apps: (google them)
fb messenger -> Messenger less crap
Instagram -> OGmods Instangram+
Whatsapp -> OGmods OGWhatsapp
Youtube -> OGYoutube or Youtube app + xposed modules
Telegram -> Plus messenger (My favorite to admin all channels)
and so on....
You can do the same with RomToolBox pro and grenify to take full control
On what version of Oreo are you? Since CRC7 Battery is very good for me. Maybe it's even better than on Nougat before. Using Light ROM with NX-Kernel.

I found this version here on XDA, because every official Oreo rom I was trying to install through Odin I I was getting error after flashing shoot.. it's a error with CRAP rooms something like that I read.. I found a thread here to fix it with zip tool to unzip the rom and delete something from it but I got another error. I was trying for like 5 hours.. and I found this ROM I have now.. also on a telegram group I found the AEL kernel free and I install it, I am using Synapse app to configure the governor etc.. which governor do you suggest me for the best battery life ? I was using blu_active and one more I don't remember it's name but I got a lot of lag..

Okay, firstly are you rooted and have twrp installed? If so then just flash one of the many roms available, most of them are now based on newest available firmware, and install a kernel like noxx or one of the others.

I forgot to mention that I have the App "SD maid pro" for clean the device every 7 days at 2:30 am and then rebooting itself, so you start your week with a fresh and clean device. You can also automate most of the task by using "tasker" app.
Recently I create a profile to set "GPS on High accuracy" when apps like Google maps or "Maps.me" are open and change to "GPS on Battery saving" when leaving those apps.
Another tweak to save battery is create in tasker a profile with the csc of your mobile company (in my case CNT) and near to my house are 4 antennas of this company to set the WiFi On when connected to those antennas or wait 5 min to Turn Off the Wifi when those antennas are not available anymore. You can add more Antennas from your workplace, parents, gf, bf, ggs, and common visited places to never have to worry about the WiFi and saving battery, because you are already connected to those antennas so Tasker use almost no battery.
As I mention to you, even with those and another tweaks I have to charge my s8+ twice a day, but at least not 3 times a day xD
You are welcome, if you need something else just let me know, most of the info is already available on XDA, which ones to use is the deal, so chose wisely my friend....
PD: Try not to bootloop your phone in the process xD

So that's custom ROM with TW ui Right?
Correct, it has touchwiz (Samsung experience) ui
Fully stock here. No greenify/custom placebo crap and I'm getting 6h+ of screen on time every day with a mixture of LTE and WiFi. And I also use all the usual suspects (Facebook, fb messenger etc). Sometimes less is more, stop installing a million crap applications to "save battery", they're probably doing you a lot more harm than good. Battery on stock Oreo is just fine.
Normal s8 btw, not the s8+.
