Which kernel am I running?

Hey all, quick question hopefully you all can help me out with. I am currently having terrible battery issues ever since I flashed my phone initially. Terrible as in 6 hours stand-by my phone would be dead.
Anyhow, I am just trying to figure out who's (which) kernel I am running. The kernel version is 2.6.35.7-I997RUXKG3-CL366622 . I have done searches but biggest problem is, threads usually do not post the version number for me to check what I am running.
I am on Infused 2.1.0 (thx GTG!), but battery life has been garbage on all ROMs so I am certain that is not the issue. Can anyone let me know, me love you long time.

Maybe u just have a bad battery 6 hours is horrible off stand by.
unless you have some other things running thats eating it up. when you check your battery stats whats eating the most power. Display? Android Proccess?
check that out.

Thanks for suggesting CPU Spy, looks like I am running Infusion-GB which is what I wanted. So something else is killing my battery

Problem is I bought 2 extra batteries and get exact same life. When I initially bought the phone I would get a days use surprisingly. After that, I have had nothing but god awful drain. I have had almost a dozen android phones and have never encountered such terrible battery life.
I do not have fetch data enabled/gps/widget updates or anything that would normally keep the processor/data churning while in my pocket. Battery use is usually around 40-80% on display, all other categories being minimal (which seems correct).
I'm banging my head on this one, I appreciate you guys replying to my thread

1% per 3 hours standby is FREAKING AWESOME..!!!!
Maybe u have some stray app in the background that's using CPU/whatever it is that's eating up ur battery.
Some subtle things u cud try since u said display is taking up 40-80% of battery:
1. Turning off screen auto rotation, turning it on when needed
2. Turning off auto brightness, turning it on to auto when needed
Use SetCPU like people above pointed out and this would let u see what processor states ur phone is spending most time in.

It sounds like for some people, Infusion 1.1 really flakes out. No clue why. I don't overclock so I don't run it.
It's either Infusion 1.1 flaked out, or if you continue having problems with other kernels, you have a rogue app.
Kernels rarely make any significant difference in battery life unless they're broken.

Are there any apps I could get that could monitor packets in/out from what I have installed? I have a lot of apps but most are from trusted sources

Running Infusion-GB 1.1 and Infused 2.1.0: I get 1% drain every 3 hours on standby with radio on (reasonable H+ reception) and 1% every 6 hours on flight mode.
It's most likely a defect in your phone or a configuration issue. You really have to be using your phone for at least 4 or 5 hours (screen-on time) over those 6 hours to cut through battery that fast.

when you go to settings > applications > running services - is there anything there that looks like it shouldn't be there?
i know that there is a process that starts with an "o" that is tied into media hub's protected content (DRM) - eats a ton of battery, and isn't really necessary.
it's also possible that you have the SNS service going, but constantly in a restarting state. this seemed to eat a lot of battery also.
otherwise, i'd do what others have suggested and monitor with CPU spy, and i'd also suggest an app called Better Battery Stats (not available in the market - find it here on XDA by a developer named chamonix). this will let you know if you have any wakelocks that are preventing your phone from reaching deep sleep when it is idle.
definitely sounds like you could have a wakelock or 2 interfering with your phone trying to get into those lower frequencies.

wipe battery stats?

Packets in/out isn't what you want unless you also have unusual data usage too. It's wakelock stats you want - look at the BetterBatteryStats app. It used to be only on XDA but apparently it's on the market now.

I've said it before, and I'll say it again - Wiping battery stats does NOTHING on our phone. Don't go blindly telling people to do something on our devices just because it worked on another device. The fuel gauge chip on GalaxyS series phones works in a very different way than HTC phones. (Exception: I think the GSII has a more traditional fuel gauge.)

[INFO] Achieving good battery life!!

I want to share my setup with you guys for getting good battery life which lasts the day without making you compromise on the features. The primary things I've seen on the forums so far has a lot of involved setup and frankly by the time you get it perfect, you will flash a new ROM and have to re-do a lot of it and so on, overall it's not the worth the hassle.
This is usually what my days look like and I manage to last the entire day:
I keep wifi and GPS on always, regardless of whether I'm using it or not.
Get a fair bit of calls because I live away from family so they all call a lot (I have a massive family, so we are talking about 5-6 hrs of talking everyday).
I like to read news from news republic and I'm subscribed to a lot of stuff there so I go through like 2000+ articles in a given day.
XDA like every few hrs (damn ICS!).
Text messages are also flowing throughout the day with the woman being on the other side of the country and all (100+ a day?).
I have facebook on push (not an addict but active enough to mention)
My gmail, school and exchange are all on push for email so they I see a fair bit there
The setup is VERY easy to setup and replicate. It doesn't require you to lose out on features or use your phone at an anorexic level either. You don't need a task manager or watch your processor non-stop either.
So without further delay, here we go:
Pick a ROM
I'm using Seanster_GBaxe EX v1.5.1 from the T-Mobile section, you can find it here.
Get faux's kernel
The reason for this particular one is because it's given the best results when it comes to undervolting and overclocking without SOD. You can find the kernel here.
Get System Tuner
This is available on market. There are alternatives but for this post, I will be making all the references from this app.
Get the AGPS patch from crypted
This isn't for battery directly but it does get locks VERY fast and you waste less clock cycles getting the signal. Less clock cycles wasted, more battery saved. The patch is available here.
I personally use the v3.0 Google CWM Build (scroll down his post and you will see it)
Get the V6 SUPERCHARGER from zeppelinrox
This is available here. Why the beta one? It works fine.
Okay, at this point you can pretty much store these things together in a neat little folder on your SD card because it makes a perfect library. So let's get started, I'll assume that we are starting from scratch. The order for everything will be as follows:
Get into recovery and install your ROM
This I shouldn't have to explain, the instructions you can find on the ROM thread.
Install the kernel
Same with this, read the kernel thread.
Install the GPS patch
Same with this as well
Boot into ROM
Hmm.... hopefully you can manage this
Restore all your backups and apps, accounts and whatever else
Using titanium here is always good
Install System Tuner
Okay, let's get started. Although faux has done an amazing job with the kernel, there's always the personal bias that goes into making things so his balanced settings might not reflect yours (nor mine but you will be tweak even those soon).
Inside System Tuner, go to CPU:
The first you thing you should choose is whether you want to keep the 1.72 GHz OC or not. I kept it but if you want to get even more you can lower to stock 1.56 GHz or go even lower, your choice. Once you set the max, set the min to 384 MHz. Set it once and you don't need to do it again after. Leave the governer to ONDEMAND.
Now go to the Voltage tab:
Be careful here, this can crash you if you go too far. What we do here is globally undervolt, you can do that by hitting the -12.5 mV button over and over. I use -75 mV (press the button 6 times, for those bad at math). Keep in mind that all chips are NOT THE SAME!!! -75 mV might be too much for you or you might even be able to get to -100 mV, find out by doing it.
Now go back to the CPU tab and hit Boot Settings:
Hit Screen-off behavior:
Governor - No changes
Max frequency - 384 MHz (push doesn't lag at all still so don't worry about notifications)
Max frequency/in call - 384 MHz (yes, calls don't require full blast, they work fine even under 500 MHz)
Now go back
Hit Governors behavior:
Sampling rate - Unchanged (faux has it done perfect)
Up-threshold - 75 (what's this? This means that the CPU will scale to higher frequencies when the load is above 75%)
Power-save Bias - 70 (what's this? This means that the CPU will be "biased" towards lower frequencies when load is below 70%)
Setting the Power-save Bias higher than the Up-threshold is obviously stupid so make sure you did it right.
Now go back
At the bottom, there is a whole bunch of tweaks:
Hit Re-apply CPU settings, choose init.d script (you can choose boot too but init.d works 100% of the time)
Hit Boost app loading, choose init.d
Hit Clear cache, choose init.d
Now go back
Find the Startups section and disable whatever you don't want running at boot (this is purely a personal thing).
Install V6 script
His instructions are very good so I'll assume that you have gotten it installed. Once you have it running, choose option 9, the 1000 HP one. Reboot. Run script again, make sure you've got it at 100% supercharged. Done. Reboot just to be sure again.
All done! Now, I know that was lengthy but here's the awesome part. Make a titanium full backup of System Tuner and you NEVER have to do that again for ANY ROM as long as you use the same kernel!! The script is unfortunately the only thing you have to re-apply, probably that has a quick setup too but I'm new to it so I can't give you shortcuts on it.
Hope you have luck with this and it works for you. I promise nothing and if you break your phone please don't come crying to me because you chose to do this yourself. It works for me so I shared it!! Any suggestions are welcome of course.
Note: NO task manager required!! I will modify this for cm7 if needed.

nice job. thanks a lot!

Are you in an LTE market? A full day on LTE would be pretty awesome.
For the screen-off behavior, do you think one can get away with using the smartass governor instead?

I'm using the RC6, tad older I guess.

I'm not in LTE area :-(... Would be nice because that's why I got the phone but then I had to move so can't say anything about LTE.
As for smartass, what kernel are you using? Smartass works very similar to the modified ondemand settings that I set up so it wouldn't make a difference as far as I forsee.

If you could post screen shots of your CPU Spy that would be helpful! How well does your phone do on going into deep sleep? On average from what to what time does yours last you? I'm just skeptical about setting the screen off behavior cause that usually prevents the phone from going to Deep Sleep.

Dont you think the phone waste alot more battery though when it doesn't go into deep sleep? I've also found that WiFi tends to create a nasty wake lock. My set up is Sky ICS Speed with Faux Clock 1.296 ghz max -384 mhz min. -37.5 u/v LTE on all day, extremely heavy usage. 12 hour battery life on average.

From what I've noticed with the faux kernel, it goes into deep sleep after some time on it's own, regardless of the screen-off behavior. I haven't opened up the source to check it out for a better explanation but that's something I doubt is worth exploring since the performance doesn't take any hit.
I haven't chosen to underclock to 1.2 but it should do better than the 12 hrs I get now if I did do that. I have a tendency to start GTA 3 and start playing whenever I get bored so that's why I went OC rather than under. For others looking strictly to use the phone with minimal gaming, this would be a good option. LTE isn't available in my area so I can't test with it but the WiFi radio uses just as much battery as the LTE, if not more I have a feeling.
Trying eugene's kernel from today to see if the lionheart governor does better than the current setup. I will know in a couple of days because every ROM flash needs a couple of charge cycles before it accurately shows battery status.

Do you get any SOD? Everything working okay? Is the setup different than what I've got up there? Would like to know and try it out, can update the OP accordingly.

Just finished with eugene's kernel and the results were pretty disappointing. Looks like the second core is always kept on regardless, faux's kernel turns the second core offline until usage demands need it.
If anyone knows how to tweak eugene's to stop that from happening, do share.

Using darkside ROM at the moment with the faux kernel, had the Eugene kernel but I noticed that the second core is kept alive regardless of usage and that wasn't helping so I changed back to faux.

Did it last night, and lasted the day without a sweat! However, my min frequency wont stick? I have it set to stock frequency 1.5, using faux kernal, and my voltages arent as low as yours (im not a crazy user like you.. maybe an hour of talking a day, lots of texts and emails tho), but i cannot get my min frequency of 3xx to stay. Suggestions?
Thanks!
edit- running stockMod v1.0

im sorry, i have a hard time believing you talk for 6 hours and scroll thry 2000 pages of web and get a day of use. I myself could get about 1.5 days on battery strictly by staying home, connected to wifi all day and barely talking on the phone. i would like to see a screenshot of battery usage at the end of your day

I've installed it last night. My usual morning lag that I experience wasn't there so I believe there is some merit to what this mod is supposed to provide. I'll be tracking the battery life, as that's more important to me than a reboot once a day.

Yes I can also confirm that this app works. Even makes one of my slowest apps (amazon appstore) open much faster. Everything is a bit quicker.

My only concern is battery life, which I am going to be testing over the weekend. Loving the mod so far though.

I can verify this works well use to take close to a minut to load my xda ap lol. Not so any more. Also switching from app drawer to home screen, no lag. I used v6 supercharger for a while and i think that for now im just gonna use this. My phome is much more responsive than it use to be, especially when opening my settings menu. I will be paying attention to battery as well. Thanks for your work.
Edit. My cpu clock speed magically set it self to 1552. Dont ask me how that happened cuz i dont know. Now normally at this speed my phone would freeze. How do i know this? Cus its happened on more than one occasion. I dont overclock anymore because of it. I ran this app all day with no adverse effects. I cant say one way or another if this app works because i dont know when my phone was set to overclock. With the controversy surrounding this.... Im glad i didnt pay 1.50 for it or id feel like a really dumb***

From his post:
"So to be clear... IMNSHO, the recent entropy pool fad is bull****. The only users of /dev/random are libcrypto (used for cryptographic operations like SSL connections, ssh key generation, and so on), wpa_supplicant/hostapd (to generate WEP/WPA keys while in AP mode), and the libraries that generate random partition IDs when you do an ext2/3/4 format. None of those 3 users are in the path of app execution, so feeding random from urandom does nothing except make random... well... less random
The only conceivable reason some devices may feel faster is because by constantly polling the PRNG, it keeps the device's I/O in constant use (which in turn, depending on device, will make the CPU stick to higher clock frequencies to keep up and/or ramp up the IO scheduler)."

Yes it's bullish**. The whole explanation for this mod doesn't make sense and I just can't figure out how this would help at all. As RC said excellently, it would simply prevent I/O functions to go to sleep and keep your CPU higher. TL;DR : Raise your CPU clocks, change your I/O scheduler and you'll get better performances.

One more thing... I dont know when my phone was set to overclock but here are some interesting screen shots for you.
This is a 1500Mah stock battery. The original batter. I got with the phone over a year ago btw.

Isn't faster performance accomplished by keeping the I/O constantly running and the CPU at higher clock speed than it would otherwise be?

Call me crazy but using this made my phone constantly stay in deep sleep! I've never, ever seen my phone stay asleep for so long and so consistently before.

I've been using this mod for a little over a week. While RC might be right about what this mod really is doing, my phone hasn't been snappier. As for battery life, I've lost about 10% more battery a day using this. I've got the Anker 2800mWh battery, and at the end of the day I'm usually sitting around 55-60% battery remaining. On hard use days I'd be around 30% battery remaining. Overall I'm still getting a full days use out of the phone.
If someone could suggest what scheduler I should use (instead of this mod) then I'd gladly try RC's suggestion and see if he is right as well.

[MOD] Eliminate Wakeup Lag - XXLSZ

Hi guys.
Here is a mod I made to eliminate wake up lag on lock screen when pressing home button.
this mod is on the file androidpolicy.jar
my mod includes 4 way reboot and ink effect (WITH PEN ONLY)
download file and flash in recovery.
Thanks to MIKEYXDA for How To.....
Feel Free to use this in your ROMS, but please give credits
this mod is for LSZ!!!
PLEASE READ: This mod adds a wake lock to your phone and could prevent it from going into deep sleep.
I've added the Q and A from MIKEYXDA guide so you can make up your own mind.
please make a backup first!!!

Just to let users know this mod may not put your phone into deep sleep coz what the mod does is create a partial wakelock - that is how it enables zero wake-lag.

I did a lot of research on that and it's not so easy to answer. Generally, I believe battery will be no worse and possibly better. Google location services, alarms, widgets, push mail, and many other processes end up waking up 99% of phones at least once every 3 minutes anyway and the deep-sleep-->awake-->deep sleep cycles actually consume more power than letting the processor(s) stay awake. On my phone for example, Google location services alone woke the phone 20 times/hr (every 3 minutes) and that's with GPS turned off and no navigation or map activities running! Add a weather widget here, a push mail app there, and I found that my phone was bouncing in and out of deep sleep more than a hundred times an hour! Better (on both battery and circuitry) to just idle at that point. With only one CPU awake with screen off, the radio will draw more power than the CPU idling. Most people don't realize that the screen and radio eat orders of magnitude more power than (especially an idling) CPU, so idling one CPU will have little effect on battery. That said, I suppose if you put your phone in airplane mode and maybe froze a bunch of other apps that wake the phone, maybe battery would be worse with the ZeroWakeLag wakelock and the phone would do better in deep sleep. Reality is: we don't use our phones that way.
I guess the only way to test this is to run the mod for a while and see how it goes.
my battery I ****ed anyway and I have to charge twice a day so its not much of an issue for me, but for all you battery hungry folks out there it may cause issues.
would be nice if users could report any differences they see and we can together figure out if it is more of a hindrance than an advantage

deleted...should better read myself

Thanks.

forget it...was for homebutton doubleclick lag...yours is for homebutton lag on lockscreen...sorry

First thing you should know is that I am not a technical person, but a logical man. Following is my personal views. This mod may not put the device in deep sleep at all. In the cpu spy you will find above deep sleep, 200, 500, 800 mhz bars. Normally you may find even the deep sleep shows a good % the other bars 200,500,800 also show varied %s.
So may be this wakeup lag mod control these 200,500,800,1000 mhz to near zero, then overall battery consumption could be very less. Only experiments can answer this.
I shall flash this and see any difference.

haha OK no worries.
Eybee what are your views on the wakelock? think it could affect battery more than what you gain from the mod?

I don't care that small lag, cause I know as long as it is present, my device was in DeepSleep ...someone would have to test it for 1 day or so and check with CPUSpy if DeepSleep is 'normal' or not...

after almost a full day of use I can confim the device is not entering deep sleep.
spending most of its time running at 200
do you think this will have a massive affect on battery life?

Actually I was waiting for your reply.(pls refer my earlier post). Another thing is I have already got 4 way reboot and ink effect. I just wanted wake up lag mod. Any way I shall flash. Already made backup. Let you know after 24-48 hours. Thanks.
Rom: Team Union V6 Full.

The problem with this mod is that it is integrated into android.policy.jar and if users wanted to disable it, they will have to flash the original android.policy.jar of the rom they are using. To achieve the same effect without modifying android.policy.jar, xda member sms200 has made an app that integrates this zero wake up lag in his app and users will be able to test or use it at will. HERE is the app and HERE is the post for more info. Just install it and enable/disable Permanent PWL.

I read through most of that tread and missed that bit lol
What ive done is copy original androidpolicy inside framework as androidpolicy.jar.bk and then copied original so i can revert at anytime. This is included in my rom aswell (both files)
Feel free to use my mod or the app depends what users prefer.
Dsmas - the 4way reboot and ink effect is included because if i didnt and you flashed the mod you would lose both functions.
Ive been testing some sharedpref mods and a remote control app so i might be able to create something to enable/disable in my galactus mod pack (WIP see my rom thread)

[ROOTMOD] Kernel Adjustments v1 [STICKYME]

I've taken the liberty to root my GS4 and have some time spent on tweaking kernel parameters.
For these settings you need to be rooted and have downloaded a kernel tweaking app, such as Trickster Mod.
I believe these settings should make some pretty significant changes to your experience.
Follow the screenshots for the configurations:

Any heat issues?

Since the changes have you noticed any significant heat or rapid battery drain?

Still testing. I am charging the device now and I'll report later but i'm guessing hardly anything noticeable.

Thanks for the post!
I am however curious about the use of ZRAM as this phone should easily have enough built in RAM to where that is not needed..
ZRAM generally gets used when a system is RAM deficient.. ZRAM will also be noticeably slower than using the built in RAM as well...
Looking forward to you reporting back..

I think you may be confused about ZRAM.
ZRAM is used for swapspace instead of placing the swap on the "disk" it is placed in RAM for a performance boost.

I don't think I am confused... Why use swap space for RAM when this phone already has plenty?
Then again, I may be confused..

Going to give this a shot for a little while.

How do you get to the Interactive Control screen?

I believe you have to set the CPU governor to interactive, apply by pressing the check at the top right, then going into governor control at the bottom.

This mod has reduced stutter and sputter by like 90% on my device. Will keep pushing it.

Thanks. Really seems to help alot on mine. I did leave the min cpu at default speed though.:thumbup:

Only downside is that after reboot you have to change the settings again.

You can set at boot in the settings from the menu.

Indeed. Just hit the menu capacitive button to get to the menu pictured below:

Your menu looks so different in terms of the interactive controls... I have none of those values or menus but an even longer list.
Why does your say you have power savings enabled? Why not turn power savings completely off? I still run my galaxy for like 2 days with Music playing like an 8 hour day.

Been running this since last night..
I am not really noticing any difference but will keep testing..
Disclaimer:
I already had 101 apps / processes frozen, animations set to zero, force GPU enabled and am using a different launcher. I think most, if not all, of my lag was done away with by doing that..

On the general settings, after you've selected interactive you have to hit the check mark on upper right. Then click governor control at the bottom, you should see the interactive settings.
Cant wait to find out what settings gives best battery life and performance.

Yeah. Gotta keep hitting that check mark or nothing takes.

Seems to not go into deep sleep on interactive. Is this happening to uou?
