Hi all,
I am proud to be a small silent part of this community and to see how much the Galaxy W has grown due to the collective work of our members. I feel like the phone has damn near doubled it's value now with all the custom ROMs, kernels, tweaks, etc, etc that have been implemented in such a short time. Really, I can't see how this phone could be any faster! That being said I feel their is a void in resources dedicated to focusing on battery life while still retaining acceptable speed.
Moving on to Kernel 3.X has really brought great features and speed to our phone, but at the cost of extreme battery loss. It's early on in it's development, so I think there is room for improvement. I have noticed that members are starting to complain about battery life and I for one agree that this is a problem. I wanted to open a forum where we could collect ideas here so our precious phones could ideally make it through the day (or at least a half of a day!).
Anyway, I hope this will be a good jumping off point for discussing. I only ask if members could refrain from the old, "Just change the battery!" unless the user is reporting the battery is more pregnant then a Kardashian sporting twins.
Ideas
Some ideas to post about
ROM
Kernel
Governor
I/O SCHEDULERS
Tweaks
Apps
It would really help if contribute ideas on how to improve our battery life even for just a little.

I've had some success using conservative + row.
I'm really hoping to find a kernel that has more optimized conservative governors. Anyone have any tweaked conservative governor experience? I was looking at Scary or Lion heart, etc?
Btw I'm on RC 6 + Chronos kernel.

I'm going to try Governor: Conservative. Is it better than SmartassV2? Anyway, I'm going to find out, just finishing the charge to 100%. I'm gonna test on CM10 Alpha 6 + Athena Kernel. Will report back after draining.
Okey bro, im using smartassv2 with athena on cm10. I'll post my observation here.

I'd love to get a CM9 or CM10 RC7 with 2.6 kernel along with a kernel 3.0 version for people who loves kernel 3.0
I am not asking to develop 2.6 kernel further. Previous 2.6 kernel is very good, but we need a ROM (base updated/sources updated) which can support 2.6 kernel fully. 2.6 Kernel was giving me much better battery life compared to kernel 3.
i tried flashing respective 2.6 kernels on CM9 and CM10 RC6. It seems to work fine but if i plug the usb cable to pc then all memory cards get unmounted. ie.. i can't copy files to phone or vice verse. I hope arco gives us a updated source for 2.6 kernel with RC7 release..
My suggestions for better battery life:
1. First thing first: make sure your battery is not dying; if it's bulging, replace it immediately.
2. Use a kernel that's undervolt-able. I use ICS, and Yoon.Kernel is perfect for me.
2a. Then, undervolt your phone. The Incredicontrol app is usually compatible with the method used by your kernel. Or, read the kernel's thread to find out which app to use.
3. Use Greenify (app) to 'hibernate' apps you don't need to run in the background at all times.
4. If you have the money (and can purchase apps via the Play), purchase "Autostarter" and disable apps' starting points. You should focus on the "After Startup" and "Connection Changed" events.
5. Every now and then, while the phone is on, turn off all data connection (wifi or 2G/3G), turn off sync, and let your phone charge to 100% *and* keep charging for awhile (trickle charging, 1-2 hours should be enough), then let the battery drain until your phone shuts down (by using it normally). Let the phone cool down, plug it into the charger, and power it on, and let it charge until 100% again.
6. Use BetterBatteryStats regularly to find apps consuming too much power and/or holding wakelocks too often; complain to the app maker, and replace it if the maker won't/can't change it.
7. Remember to turn off wifi and/or use 2G only mode when you're no longer using them.

Pep, with full respect to your suggestions that are legit, but this can´t fix the battery drain issue CM9 is having with it´s new 3.X kernel.
They all will reduce the battery drain of course,but wont bring it down to the level you will reach with 2.6 kernel.
I´m still not sure what exactly is causing this, but in my case it´s for sure not my batteries nor other apps causing this.
As I already posted in the Bug report threat, I now flashed RC6 by going totally pristine. Formated both SD Cards and whiped everything, just installed BatteryMonitorWidget to control the battery drain. It´s twice as hight in DeepSleep compared to RC2 and RC3 with it´s old 2.6 kernel.
So first of all we need to narrow down what exactly is causing this.
Therefore I suggest to install first the BatteryMonitorWidget to comapare our results and to share the settings whe have changed after installing RC6 the pristine way.
First my configuration:
1. SDCards swapped
2. Dithering disabled
3. 16-bit Transparency enabled
4. Freeing up resurces enabled
5. Kernel sample Merging enabled
6. Zram disabled
7. default governor and scheduler
8. Syncing Accounts disabled
9. Updates and notifications in GooglePlay disabled
10. Wlan and MobileData disabled
11. Baseband XXLMB
My results with 2.6 Kernel are:
~16mA at daytime in DeepSleep
~ 5-8mA at night in DeepSleep
with kernel 3.x
constantly ~35 - 50mA in DeepSleep
and I checked it´s really in DeepSleep Mode.
So it looks like the radio is consuming more power while keeping the phone connected with the radiostation while the phone is in DeepSleep.
but....
I once also tested hadi´s 1.6 yoon Kernel with RC2, which is basing on Arcos RC2 kernel. By using the Ondemand govarnor in his kernel to compare the battery consumprion against Arcos Ondemand governor, hadis Ondemand governor also comsumed more than Arcos Ondemand Governor. With his OndemandX givernor the consumption was pretty much the same like with Arcos Ondemand.
So maybe it´s also something that changed in Arcos ondemand governor in 3.x kernel.

i don't know how will you classify my battery life because for me if the battery is enough to last at least for 8-9hours(hours spent in college) then i call it good enough

1 think usually done wrong in forum i'm following is they're using task killer or app to manage their free ram. this app is THE REAL BATTERY KILLER. they stop needed service and make your phone awake . not to mention the choppyness because the os needs to restart services and many bad effect it causes

Oh I see there are several apps out now using the same name.
I´m using this BatteryMonitor Widget from 3C.
So when using it:
1. Do not recalibrate the battery as it will otherwise need much more time to show you accurate readings.
2. The App needs at least one or two charging cycles to recalibrate itself (not the battery) as it needs to determinate the exact capacity of your battery.

Hm well I´m used to recharge my battery every 3 to 5 days because it´s most of time in DeepSleep Mode. I´m just doing calls and surf the net in my breaks at work. So only turning on MobileData if it´s needed. At home I´m having my PC for surfing the net, so MobileData and WLAN is disabled as well.
With RC4 my battery drain was so high it even wouldn´t last as long till I´m back home from work. With RC6 i think it would last at least 12 to 18 hours, but it´s still a huge difference compared to the RC´s with it´s 2.6 Kernel.
Agree with you about using such apps like Task Killer or scripts like V6 Supercharger. They all need extra CPU time to do their jobs and often are causing more problems than they are solving.The Android OS can manage such things better itself and terminate unneeded services itself too.

Additionally you can use BetterBatteryStats in case your phone is keeping a long time active to see what is causing this. It´s free for XDA members.

I can testify to this, my BBS shows the phone going into deep sleep normally but the drain with data on is immense even in deep sleep. Your initial findings already point to the most likely source of the problem. Given the varying opinions on this(some say it's fine I others don't agree), is it possible we have the same device but different hardware revisions, some of which are much more power-friendly than others? Because for the life of me I couldn't NEVER anything more than a day from kernel 3.x(CM10) but some people claim they could get upto 3-4 days on light use!
Sent from my Wonder powered by CM10
I don´t think it has something to do with different hardware revisions, else it wouldn´t matter which kernel is in use. But it does.
There is for sure something strange going on. I´ve additionally installed BetterBatteryStats and now the phone started keeping very often in awake mode. Not sure this has something to do with this app, because it didn´t happen when I had it installed on an older CM9 release.
However I can´t find any suspicious processes that are causing this. But to be sure I will have to go back to RC2 to compare with.
So here my results:
Within of 5 hours it keept Awake for 25 minutes.
BBS also says NO Data Connection and No or Unknown SIgnal during that time
But I´m sure it was connected to the radiostation and made a short testcall.
About wakelocks:
KernelWakelocks:
"mmc0_detect" 4m 32s
"DPRAM" 3m 11s
"alarm_rtc" 2m 21s
"PowerManagerService" 1m 36s
"radio-interface" 1m 10s
"alarm" 36s
"mmc1_detect" 13s
Partial Wakelocks:
AlarmManager 44s 997 Counts
GSM 20s 4 Counts
ActivityManager-Launch 18s 104 Counts
sleep_broadcast 4s 23 Counts
RILJ 2s 146 Counts
*backup* 1s 109 Counts
NotificationService 1s 113 Counts
Ok I´m back to RC2 and am having some results from BBS to compare with.
After fully charging the battery I unplugged the phone and left it over night at the same place I´m always leaving. So the conditions were the same like with RC6, though in RC6 there were no apps exept BatteryMonitorWidget and BetterBattery Stats installed.
To make it short the results are nearly identical. Even the Awake time is almost identical in a period of 5 hours.
There is also the No or unknown Signal entry for the whole time. So I guess this is due to the MobileData being disabled.
But what I´m missing in RC2 is "mmc0_detect" and "mmc1_detect" in the Kernel Wakelocks. They are not showing up there.
So now we need some other results to compare with my results.
Been using this phone for 1 and half year now..is it normal to have a battery life of 5 hours with 3G on? Currently using cm10
I think the 3.0 kernel really makes a big difference in a negative way in regards to the battery life.
To fight against this, I have used the following settings for some success:
Conservative + Row... still very fluid with Yoon Chronos
245 - 1024 MHz
Screen off after 30 secs
Under volt
Its much better than before, but still I would like more battery life. Probably 8 hours with heavy use up to 16 hours lite.
Sent from my GT-I8150 using xda app-developers app
Agree on that. I tried now RC6 together with hadis chronos kernel and the consumption is the same like with Arcos 3.x kernel.
The "mmc0_detect" and "mmc1_detect" entries also appear with hadis chronos kernel. Not sure they are responsible for it, but they didn´t appear with 2.6 kernel.
So what I can say for sure it´s not the governor but something else in the 3.x kernel and so far these mmc detect entries are under suspicion.
First of all, sorry for not testing against the two kernels; there's a major project going on in my office, and I totally can't risk to be offline... plus with the random times I'll receive calls, the battery usage might be skewed...

I did some Google search and arrived at the following thread:
http://forum.xda-developers.com/showthread.php?t=1827676
scroll down to the second post. The OP of that thread noticed that mmcX_detect will utilize a lot of wakelocks if the SD Card is defective.
Since the battery drain issue with kernel 3.0 does not seem to happen to everyone, could people experiencing such drain try the experiments without an SD Card being installed?
Sent from my GT-I8150 using xda app-developers app
No problem pep. I need my phone too during the week, so only can do some tests at the weekend.
So to narrow down this problem we need to know how it works without a SD Card installed and if all who are having this issue are having the SD Cards swapped.
I have upgraded my Galaxy W to Jelly Bean using Custom Room (4.2.2) Cyanogenmod 10.1 alpha 2. maybe later alpha 3.
Everything runs well. but why my phone's battery drains so fast? and please help me HOW TO SOLVE IT AND MAKE IT LAST LONG TIME???
THANKS VERY MUCH....
Backup your apps, factory reset your phone. If battery drain problem persists, install Greenify or deep Sleep battery saver from Google Play to better manage battery resources.

when you just flashed the battery will definitely be shorter. Let it recharge for a few cycles before determining whether its good or bad battery life. Keep in mind however that even at full potential, the battery will not last for more than 2 days even at light usage.
if battery life is more important to you compared to "the newest OS" and whatever extra features it brings with it, then I highly recommend installing acro's CM9 RC2 (yes it is ICS) as the 2.x.x kernel is far better at battery life than 3.x.x (i'm currently testing it and I can already feel the difference! I believe I can reach 2.5 days at modest usage but I will have to update you on that after my first few discharge cycle for battery to reach potential after flashing new rom). I do, however notice a few annoyances with RC2 (not sure if its really the ROM, or the custom kernel i'm using, or Nova Launcher is to be blamed), so if it continues to bug me I may just switch back out to latest ICS =p.
If keeping with the latest JB is important for u, best thing you could do is download a custom kernel for it that supports UV(undervolting), then get IncrediControl and tune down your UV based on some voltage tables you can find in FAQ. This alone won't bring you a HUGE improvement in battery life but its definitely an observable difference. On top of UV, try to UC(underclock) your CPU to 1GHz. Most daily functions, apps and games (depending on how intensive it is) will work perfectly smooth even at 1GHz. IMO, the most important point of UCing is you will notice a very significant difference in the heat of your battery (ie backcover of your phone). Heat is generally bad for the battery (shorter life + faster draining) so UC is definitely a good thing to do =). Of course, on top of all those, get greenify and wakelock detector(WLD) from market to control your not-so-frequently-used apps. Use WLD to track down what is keeping your phone awake (hence drain more battery) and use greenify to hibernate all the not-so-frequently-used apps you have (example of things you DON'T want to greenify: whatsapp and gmail as you don't want to kill these 2 programs when you lock your screen. You want to continue receiving whatsapp messages and gmail when you locked your screen right? XD! Examples of things you SHOULD greenify: games, music player. Maybe some of the games or other apps may keep a background service active, secretly using your battery even though the last time you used it was 2 days ago!)
Finally, if your wonder is about 1-1.5 years old, chances are your battery is already bloated (perhaps you can feel your battery through the backcover of your phone even!) A bloated battery is a dangerous and short-capacity battery. Even with the best rom you may only push through a day from 100-0%. If your battery still looks fine but your phone is nearing its birthday, go ahead and do some online shopping (ebay or local equivalent, like malaysia we have Lelong.com.my) and get a battery for your phone. Its usually much cheaper than buying from telephone shops.
EDIT: Adding on to all of that, choosing a good governor+i/o scheduler combo is important as well. If our phone is similar with the S+, smartassv2+sio(i've used this, its quite smooth and battery is good) OR OnDemand+noop is thought to be very good in terms of battery life and responsiveness. Lulzactive is also very good but its not so easy to tune it so i usually would stay away from it. Do bear in mind that although the former 2 combo is good, it still highly depends on how you use your phone so there will not be a universally best governor+io combo. Both of those suggested by me are supposingly best in responsiveness as well as deepsleep battery conserving (only if the assumption that our roms work the same as the roms tested in S+, which MAY NOT be true).
TL;DR? try smartassv2+sio (u may change this using IncrediControl, get from playstore). Then if you are not satisfied with your current performance/battery life, you may continue experimenting by changing governor and i/o scheduler one at a time. If you are doing the testing, make sure to have some way to record your tests if not you will 100% be deceived by placebo!(with actual numbers you will clearly see whether your feeling is placebo or if there really is an improvement)
I'm having some seeeeerious battery issues with alpha3. With just 15 minutes screen usage in a day, battery settings says my screen used up more than 20% of the battery! This just for consulting the time and the weather.

that 20% is not actually the 20% of the battery juice. It is 20% of whatever amount of battery is drained due to the display being ON. Like if your battery is used from 100% to 90%, then only 2% is used by the display.
I am not sure if I could explain what I mean.
EDIT: Hmmm maybe I misunderstood what you said... If that is the case, disregard.
And also my galaxy W will use all of its battery charge when the display is constantly ON for about 3-5 hours.
Actually, I've figured out what it was. It was Google Now. Chewing away at the battery without saying a word anywhere in the battery screen. I am now back to my old 3 days battery.
you need to install cpu spay from google play and you need look deep sleep time.
this reaction is typical if your coming from a stock or at least cm9.
there has been a lot of arguments about battery life of cm10 and above.
in my opinion, there really is a difference, i mean cm10+ drains battery faster.
and the reason being is of course the features there is in cm10++.
if you're after battery life, stay with stock or cm9 (for now).
but if you feel like your in with cm10+ and you don't want to go back like me, then may want to try these tricks:
1) using Titanium Backup, freeze the apps that you don't really use.
- in my phone i froze pico tts, voice search, talk back, etc. (i even froze google search )
2) i use an app called "autostarts", it can disable auto starting of app including those of the system.
- in my phone, i disabled google maps in every activity. ex. after startup, connectivity changed, wifi connected, widget updating
3) disable system settings which also contribute to battery draining.
- disable location service when your not using it
- disable automatic backup/restore
- disable haptic feedback
- disable autosync
- disable the top battery drainers when not in use (wifi, mobile data, gps, bluetooth)
- and many more just explore
4) do not use so many widgets (my home screen has 0 widget)
5) do not use live wallpaper
6) charge only using the original charger, not from other phone/brand, not from a usb port
- the best way to charge is to avoid using the phone until it's fully charged
7) finally, install only apps that you really need. just keep a backup of your not so often used apps and install only when you need them
If you think about it, everything i wrote above contradicts with the original concept of Android.
But that's life, sometimes you have to trade something in order to achieve another.
Our phone was baked as Gingerbread, now we want to make it taste like Jellybean.
We have all the ingredients, but we don't have a jelly bean pan to make the candy molds.
So we improvise, we work around, we do some shortcuts, we make alternatives, certainly it will cost something.

- in my phone i froze pico tts, voice search, talk back, etc. (i even froze google search )
2) i use an app called "autostarts", it can disable auto starting of app including those of the system.
- in my phone, i disabled google maps in every activity. ex. after startup, connectivity changed, wifi connected, widget updating
3) disable system settings which also contribute to battery draining.
- disable location service when your not using it
- disable automatic backup/restore
- disable haptic feedback
- disable autosync
- disable the top battery drainers when not in use (wifi, mobile data, gps, bluetooth)
- and many more just explore
4) do not use so many widgets (my home screen has 0 widget)
5) do not use live wallpaper
6) charge only using the original charger, not from other phone/brand, not from a usb port
- the best way to charge is to avoid using the phone until it's fully charged
7) finally, install only apps that you really need. just keep a backup of your not so often used apps and install only when you need them
If you think about it, everything i wrote above contradicts with the original concept of Android.
But that's life, sometimes you have to trade something in order to achieve another.
Our phone was baked as Gingerbread, now we want to make it taste like Jellybean.
We have all the ingredients, but we don't have a jelly bean pan to make the candy molds.
So we improvise, we work around, we do some shortcuts, we make alternatives, certainly it will cost something.

This might be my S2, or it might be my W...but it's definitely CM
Hi. I just want to know how can I save more battery on this rom, cm cause when I had the TouchWiz stock one, battery lasted about 7-8 hours, with heavy use. And now with CM10.2 it only lasts about 5-6 hours, same use. How can I set the governor or which are the best performance settings for this rom? Right now I'm using interactive governor. Also, is it normal to take about 1 minute for the phone to boot? I have foldermount installed, but I don't know if it's the cause of this. Thanks.

I use the Slimrom myself, so not sure about CM, but 1min I think is a bit too long for the S4 mini. You may also want to try a customer kernel: http://forum.xda-developers.com/showthread.php?t=2568479 by F4k, its pretty good and stable. As for the governor, it situation dependent, some may perform better than the other depends on your installation and kernel. Generally ondemend, interactive and smartassV2 are pretty balanced between power saving and performance. There's few app you can use to set governor, its a basic function and they all work: https://play.google.com/store/search?q=kernel tuning&c=apps&hl=en
I don't use foldermount, but those type of APP do use quite a bit of process, especially now a SD card is involved. You can use: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en or similar program to monitor and see which process/program consume the most power.
Standard tweak are simple, disable unwanted radio, use the 'black/dark' version of the menu, don't use over-complex launcher, etc. I'm not sure if CM has the KSM feature (Kernel SamePage Merging) in the settings menu, if you do and happen to use it, disable it. It waste about 30% of the power.
No need for anything fancy. Ondemand governor is the usual "standard" and gives me great battery. Smartass has always been awful on devices ive tried it. make sure you don't have programs like Facebook running in the background. Most likely its an app causing your drain.
Hello,so what kernel you like to combine with PA? -Nexus 4
I've tryed few
Franco r203-i think is has a battery drain problem /no update till now...
Trinity-no gama controll(and that is pretty annoying for me)
faux-idk why i just dont like that kernel
matrix-ok battery but low fps in gaming(maybe im doing something wrong?)
hellscore-hmm idk how its now ....
I would love to try ElementalX but its only for N5
The "wish list"
-over 4 SOT in wi-fi(3g,bluetooth,nfc,data,gps-all OFF ,dont need them)
-has customizable color-gama
-low consumption over night
-NO low fps in games like Asphalt 8(can change pref with Per-App modes if need [low on daily apps and custom profiles for games])
Thats all
What do you recomand?A few pros/cons on the kernel.
Try hellscore b43
http://d-h.st/users/hellsgod/?fld_id=27672#files
hells-Core-b43-kk-t2.zip. Flash this file. Enjoy!
This kernel gives better battery life for any ROM. 100% results.
After a day of testing more kernel
My favorite for now are:
Trinity- 4cores on all time and combined with tkt for gamma
Hellscore b43 -its very cool ,i'm very curious how will perform over night the b44 version because the low frequency
This 2 i love the most
For what it's worth, I have no exceptional battery drain using Franco Kernel. I lose ~1% per hour with the screen off, and <0.5% per hour with the screen and radios off, which is as good as it get for this device, in my experience.
With normal usage and without disabling Location Services or radios, I tend to get 5 hours of screen-on-time; sometimes more.
So till now trinity and hellscore in 5% drain i get over 15 min of youtube playback but on franco r203 in 5% i get like 8-9
Edit:I've changed from 1,5 to 1 and now it's battery drain is much better ,like the other 2.
Lupus kernel. I was using the awful one that came with FreeXperia but that was crashing 20 times a day. Finally found Lupus and it hasn't crashed since. Battery lasts at least four times longer too which I didn't think was possible, and I haven't seen since using the stock ROM.
(Android has crashed once but that's because it's Android)
*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.
