Rooting for battery life? - T-Mobile Samsung Galaxy S II SGH-T989

Would rooting help in any way with my currently abysmal battery life? My phone doesn't have a warranty now, regardless and I own it full out.
It just eats battery like no tomorrow. I'm sort of scared to do it currently, but if it's worth the risk, I'd give it a try.

You can root and install something called Trickster Mod, go in the settings, set the max cpu to 1.35GHZ, click apply, and edit the governer settings to hi speed freq to about 810MHZ, and go high speed to 90, and click apply again.
Then go to settings and click apply and set on boot.

You could use gsam or better battery stats to figure out if an app is waking your device, then disable it. If it's a system app then you may need root.

Improve battery life?

How can I improve the battery life of my play with rooting? I don't want apps that kill every background app though as I may want to go back but it would be killed

Assuming you're on a stock rom theres a couple things you can do. The easiest would be to root and use Titanium Backup to either freeze or remove the bloatware from your phone as it runs in the background and causes drain. Another would be to look into using some of the tweaks found here:
http://forum.xda-developers.com/showthread.php?t=1227269
Another option is to try running different firmwares, personally I found the older ones to give me better battery life while others found the oppisite to be true, so try a few till you find one that suits you. A more extreme approach which will yeild far better results is to unlock your bootloader allowing custom ROMs and kernels. With custom kernels you can over and underclock your phone while choosing more effecient governers (like the smartass governer). You can also undervolt your phone which will probably lead to the biggest saving. Custom ROMs can also increase or reduce your battery life, again, try a few. Personally I run at 1.5ghz on smartass, undervolted as much as possible with version 7.1.0.1 of CM7 and have great battery life. Also keep in mind the obvious tweaks such as turning off wifi, gps, 3g, brightness, etc to prolong battery life.
-EDIT- Also on older firmwares there was a problem with using "Automatic" under time and date where it would cause a lot of battery drain so you may want to turn this off if you think it might be a problem
Thanks, but I'd rather not root my phone yet. Thanks anyways

I would say update to .62 firmware it should be up for all around the world yesterday i updated my arc s to it.I was setting up the phone after (flash before the update) and i had to set up everything again and my battery is still on 70% from yesterday (im talking downloading apps,connectin accs and stuff,like 3-4h of usage and around 8h on idle while i was sleeping).My phone isnt rooted and its with stock rom and stuff
I use juice defender ultimate. It allows me to easily get a days usage out of my phone when before i barely got a day

How to set the min GPU frequency ?

Hi,
i did undervolt for the CPU and the GPU, but i have a question, on Stweak, we can put the mini frequency of the GPU at 54mhz or 108mhz.
On stock, it is set on 160mhz, anyone tried to set to 108mhz or 54mhz in order increase the battery life ?
54mhz = 825mv (stock)
108mhz = 850mv
160mhz = 938mv (stock) and mine is 875mv
Should i try min at 108mhz and undervolt at 800mv ?
Thanks
I actually don't think there will be problems since the kernel is providing it..
I guess you should try them without setting on boot.. If you had no issues then you may set it on boot.. That's the easiest way to know weather it's good or bad

Hi, i turned back to 160mhz because i got some bootloops, i was affraid of SDS.
But indeed i could remember that i got a better battery life but not impressive... You can see this when screen is on, but i got some wakelock due to low frequency i think.
So battery drained faster in deep sleep while not when screen on.
You should try but be careful, you should put a file .zip which can be flashed in recovery mode to reset settings on the kernel, because if you want to put 54mhz you have to click on "enable on boot" on the kernel settings.
sorry for my bad english

You better have to install greenify and uninstall facebook which give me lot of wakelock which drained my battery.
Now i always have 6/7h screen on time with 2days of standby which is really awesome since i use 3g more than wifi.

How to improve s3 battery life after root?

Hi I was told that after you root your phone the battery will improve tremendously but u must do it manually. Any tips, or tricks I should do to improve my battery life and not ruin the phone?

Download Greenify from the Google Play Store.
Rooting won't change anything as far as battery useage, and Greenify is a good simple option. Another is to go through your settings... set display brighness to auto - the screen is the biggest battery killer. Look for other options you don't use and uncheck them. Look at your battery stats and see what is using the most power. If it's an app running in the background, you may be able to kill the task depending on the app.
Remove all stock system apps that you do not use

[Q] Battery Problems?

Hi all. I have a Samsung Galaxy S3 (I-747) running the latest d2lte nightly build of CM11. What brings me here today is very bad battery problems. These have burdend me since I got the phone (before I installed CM11.) I would like to know what could pottentally be causing the problem. I have tried many things to fix such as turning off all not needed features, greenify certain apps, enabling android runtime(ART), going to privacy advisior and turning off all keep awake settings for my apps, and turning off sync settings. Here is a 50 minute test showing you all the battery drain(to me) of my phone with little to moderate usage. All help is appciated thanks!
Try turning off wifi, sync, NFC, Bluetooth, data, and any other toggle when not in use. Also greenify any app you can. Finally turn your screen brightness to the lowest possible setting without hindering your view.
If none of that helps, I would try another battery with more mAh.

Thanks for the feedback but as stated in the original post, all of these have been turned off and greenify has also been used. Neither helped nor solved the problem. As for a bigger battery I prefer to keep my phone slim but will consider it.
You could always try another 2600 mAh battery and see if it helps. You might also want to try a data wipe reset or restore a previous Nandroid backup....just a suggestion.

May try that too, wanna confirm its the battery before I try though as its a waste of $ if its not. I looked at the hidden menu(dail *#*#4636#*#*) battery usage settings and it says my battery is in good health. Leading me to believe it maybe my phone has faulty hardware but gonna try peoples suggestions before I say that's the cause too.

maybe a custom kernel. or read up (if needed) on kernel tweaking. my favorite was always quantum and ktoonsez kernel. just make sure thats its made for your device and android version.

Install No Frills CPU from the app store and set the min to 300 and max to 4.3. For the governor, I like ondemand and noop.

Isn't ondemand the worst? (Besides performance) and won't a CPU tuner app conflict with CM's built in one? Just making sure.
EDIT: I seen its compatible, will revert to default CPU settings on CM and try this app.

Will look into but this is a off question. (Again I'm a noob lol) will a different kernel conflict with CM?

should be o.k. i've done it many times. but then again , i would go with @audit13's suggestion first. no flashing worries ! again , just my two cents.
"all i can really do , is stay out of my own way and let the will of heaven be done"
I used ondemand on a Nexus4, Moto G, , HTC One XL, and Note 3. In sleep mode, the phones, on average, drop about 1% every 2 hours. Once you start using the phone to surf, talk, etc., the battery start to drop but it's a lot better than stock settings.
The kernel you use can also have an impact on battery performance.
There should be no problem with using another cpu app with a CM ROM. I have done this on my Motorola Atrix and Moto G running a CM-based ROM.
Thanks again guys! Will try, test and report back in a day or two.
Installed Quantum Kernel and now Android System is power hungry. It is also still draining ridiculously fast, same as before. (Didn't fully charge my phone so don't be alarmed about battery percentage.)

Alright I got a question, I'm gonna gonna flash Quantum Kernel 4.4.4 final alongside my CM11 ROM but I am using Android Runtime Instead of dalvik. Will this in anyway cause any problems?

best to check in quantum thread to see if is ART capable. i cant remember offhand if is or not.

Look up Better Battery Stats. You can get it from the play store, but I think you can find a free version posted to xda forums if you look around. It keeps track of wakelocks and system states better than the built in battery monitor.
It will let you see if you have a rogue app or service keeping your phone from getting to deep sleep when not in use.

Alright I've got myself in a minor pickle. I am currently testing Quantum Kernel and will let you guys know the results. The problem is my SMS has stopped working as in I can't send any texts. Idk if its were I played around in the Testing Menu or if its the kernel. What do you guys think?

personally never had an issue with texts running quantum kernel , but
perhaps clearing data/cache in sms would help.(?).

Increase LG G4 battery life by 30% must be rooted

*I no longer have this phone so these values and builds will not be updated if you would like to add new values for this phone or add tweaks to existing builds then feel free to post them on this thread.
*This requires root
I decided to make this thread to share with you guys a tweak that I found that really helped my battery life. I was never able to get more than 3hrs of screen on time on my phone or get decent standby times on lollipop like I did when I was on marshmallow but I may have found a solution. I stumbled on this thread: http://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557 by soniCron give the guy a thanks while you're over there. This guide is for CPU settings to increase battery life and performance. I saw that it was for the Nexus 5x and because the g4 and 5x have the same CPU I decided to give it a shot. I never noticed much performance improvements but I did notice a big battery improvement like I said before. There are many different flavors of tweaks to try and I ended up going with GhostPepper and then tweaking it to my liking.
Here are my settings for the G4 based on GhostPepper
https://docs.google.com/spreadsheets/d/1Yn-qtExspkzINkhtjHBhQyrbtSdMLH9ls4booeqsfh4/edit?usp=sharing
* 8/14/16 If you used the settings from the beta build Turtle or modded GhostPepper check to make sure your settings are up to date. I just changed some target load numbers slightly and fixed an error with the values for above_hispeed_delay. I also fixed an error with a value for the modded GhostPepper settings.
*8/15/16 Slight changes to beta settings to increase smoothness and battery life slightly
*8/17/16 Small change to beta settings to increase smoothness more and changed development status of Turtle to stable beta meaning you can probably use it without worrying about battery drain or slow downs though it does need more testing to move it to daily use
After changing these values with some type of kernel tweaking app I used kernel adiutor, make sure all CPU boosting settings like touch boost or input interval are off or at 0
After applying these settings you should see noticeable improvements in battery life
If you find any better settings add them to the thread.

Unfortunately, this requires root, so no-go on MM.

I meant to put that in the post updating it now.
I found simply changing my governor to interactive greatly increased my battery life. I am going to try this and see what I get. I'll post results.

OK great this uses the interactive governor.
New Beta Settings
I have updated the main post with a link to a list of settings one of them is the one that was on there before and the other is one I am working on. The beta I just added seems fairly decent from my testing though this is my first time trying to make my own The small core settings are ones that I did and the Big core settings are slightly tweaked GhostPepper settings. This one seems smooth from my testing maybe not as smooth as the first one I added but it does seem to have a little better battery life when doing light gaming. If your adventurous go for it and report any issues and the battery life you are getting. I also turned all thermal settings off like Core control, VDD, and Temp throttle. It didn't have any affect on my temps if anything they went down a little maybe 1 or 2 degrees but did seem to help smoothness and making sure the governor settings acted right on both profiles.

Just wanted to post an update on the battery life I am getting with the beta settings. I managed to get almost 5hrs of screen on time with the Turtle settings beating my previous longest screen on time from the images in the first post. I managed to do this with even more demanding tasks. In the first post the battery times are with mainly web browsing this time I was mainly watching Netflix and YouTube for about 3hrs worth of my screen on time. My brightness was also 10% higher than the first time. I also did a standby test and managed to only drain 3% overnight and it said I would get 139 hrs of standby time which I think is insanely good.
Battery life test
I just ran the Geekbench 3 battery test and managed to get 5 hrs 45 min and a score of 3456 on the beta settings. I managed to beat the G4 battery time by 50min and this was with 30% brightness and Bluetooth, WiFi, and Cell on no airplane mode. I also managed to beat the G3 and almost got the same battery time as the OnePlus One.

Hi, dude. I'm very interested in tweaking my G4 to get better battery life as at the moment I need to charge it twice a day. I just have a noob question, could you please tell me how you disabled touchboost using Kernel Adiutor?

Go to the CPU section then scroll all the way down till you get to a section that says CPU Boost. Set the Interval to 0 Sync Threshold disabled and Input Interval to 0. The input boost frequency will never disable for me but with the above settings it shouldn't matter because it will never run anyway.

I would try the GhostPepper settings first. The beta settings seem to give me better battery but they are still a work in progress and not as smooth as the other settings but you can use them if you want any feedback on those settings would be appreciated. I was also surprised how much those settings did for my battery life.
I decided to do a benchmark on how much of a difference there was between stock and the custom settings and to show I wasn't making stuff up by saying that I used these settings and magically got almost double battery life With the stock settings I got just a hair over 3hrs vs almost 6hrs on the tweaked CPU settings. You can see the results from stock in the IMG. The results for the tweaked settings are near the bottom of the first page.

How is your battery life after trying the settings out for a few days?
hey man i just tried yours and let we see the performance in next day. anyway the tweak that youve done is only on the CPU? no GPU or whatsoever? what if i implemented from others, let say other G4 users that tweak the GPU and i combined with your CPU tweak. any problem?
Hey man, how could I get the tweak for this setting? Thank you
I didn't think you could tweak the kernel without an unlocked bootloader for the Verizon G4 (vs98613b)?

Yes just CPU and yes you can use GPU tweaked combined with the CPU tweaks just be aware it may affect stability.

You need to be rooted then use the app kernel adiutor and change the values in the app.
