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.

Just the community kernel you can download CPU spy to help with that as well.

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.

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.)

High battery drain using JB ROM

Hai..
Im just switching to AOSP JB by AdamG Version 0.1.4.
No mod, stock AdamG ROM kernel, full wipe, just install few app such as whatsapp, cpuspy, medscape etc...this is not my daily phone..
the problem is very high battery drain..
in 4 hours battery drop from full charged to 69%..
Here the screenshot and BBS stats...Can somebody help me please to find the culprit??

Is Google Now on? it takes a ton of battery.

You need to install a better app. The Android built in power usage thing is about as much use as a chocolate teapot, and better battery stats isn't much better.
Try system panel from Play, you will need the paid version from here. Put it in monitoring mode and leave it for a few hours.
You will be able to see what is chewing CPU then, and that is invariably the thing that is causing the drain. It very rarely fails to assist me with diagnosis of an obscure drain issue.

Ok..just bought system panel app.will update about this crazy battery drain later..

Cool, it's well worth the couple of dollars.
I've used it pretty much constantly in monitoring mode since they were in beta when I had my desire. So, probably not far off a couple of years usage with me.
It doesn't eat battery either, because it polls when the device wakes up for another reason.
And the thing which really makes it good for me, it records usage of the system tasks, such as kernel threads, which can be massively handy in diagnosing an issue.

Solved by flashing latest adamG ROM..

I can't shake the Android OS from draining my battery.

I've had this problem once before and it was simply as easy as switching my kernel. You can see here.
Now I've tried GR to CM9 and then to Codename Android Build 4 still had the problem changed Kernels.. Then decided to GR to CM9 and try Beam, and yet again still had Android OS draining the battery. I then flashed the Hefe kernel and NO change.. I've looked around on forums and remember seeing someone mention strange battery stats I can't find it at the moment, but if you look at my stats below you can see that not only is the Android OS draining the battery the graph shows huge drop off points. What exactly are those? Thanks in advance for any help!

That looks like you need a new battery. A couple weeks ago I had the same problem. My usage looked the same as yours where there were sudden drops in the battery percentage. I suspect you have the same problem.

I started on stock GB, went to the 1 click stock with root and CW, to CM9, to Remi's ICS. This is what my battery looks like

@getochkn
Yeah, but you were sleeping or doing nothing, phone was idle. LOL Seriously, how is that possible? I have tried many ROMs, today I had a big issue on CM9, battery dropped from 60's% to 1% when phone got stuck and shut down. I had an emergency and needed my phone to call and couldn't. I got very pissed off and now I'm on GB because that battery drain issue has been all over ICS. I have tried calibrating, GR's, I use less apps... nothing! Phone lasted like 4-6 hours with average use. I needed to charge it like 3 times per day. It made my mobile phone, not so mobile.
Not complaining. Just a real issue. I know there are bugs and that development is ongoing. I love ICS but just can't afford to loss so much battery again in another emergency case scenario.
I would be happy to get 12 hours of use. I remember with Redux 1.2 (GB) I got 18-25 hours depending on use. Share some of your usage. I may need to buy a new battery.

Music for about an hour, wifi on most of the time, airdroid'ed into it, messing around with settings, took about a dozen pics.

[Q] Memory leak, battery problems, and screen issues.

First, my phone has a memory leak. Like, after using it for a while, even an hour or two, the available memory will go to 0. I have tried ending all apps that could be suspect, but all of the memory being used that is reported by the settings is much less than what is necessary for there to be <10MB of available memory. I even try to end as many programs as I can, but this eventually happens after some usage. Before you ask, no, I am not using task-killers, and I only notice this and end apps when whatever is leaking is starting. The phone will not effectively end enough applications to free the space. Almost every app will say "restarting" on the "running" page, and none will be seen on the "cached" page. It will result in the phone locking up and rebooting. Also, this happens during high CPU usage (might be a memory issue though), like while updating apps.
Second, my battery life since the OTA has dropped significantly. Now, I am lucky if I get 6-8 hours of battery life while occasionally using the phone and listening to music a lot. The screen seems to be taking most of the power (~65%), and the brightness is regulated by JuiceDefender. I have tried to automatically set it without JD, and it was worse in battery life. It is on much less than the wifi, yet is somehow taking up far more battery. Second place is the Android OS/System/Mediaserver combined (~20%), for whatever reason. I have tried using the Battery Calibration application multiple times and it has not helped. Disabling JD makes battery issues worse. I have looked for wakelocks, but besides the charger, I found none that looked suspicious/non-OS related. See attached file for battery info.
Third, for some reason, the dead pixels came back? Now, it looked like at first there was a shape of a butterfly in spotted dead pixels. Most of those localizations disappeared (or, the "dead" pixels came back to "life"), but a few grew, and now I have somewhere over 100 dead pixels. A few of those have shrunk, but it is still an eyesore. I can provide pictures if it will help. I'm not sure why it is doing this.
Note: all of these issues have started since the ICS OTA. I reflashed the stock OS before doing the OTA.
Any help would be greatly appreciated for any of these!

try FXZ stock ICS
freeze all unneccessary apps ...
dont install any other extra apps (downloadin from market)
try to keep minimum apps..
stay as much on 2G/Wi-Fi
ur battery should last for atleast more than 18 hrs for moderate use (else it will drain dependin on how heavy u use)
if this doesn't work then u'll need expert advice
& remember you'll get rarely above 24 hrs (usage matters a lot)
correct me if m wrong ...

I am also facing the same issues. I have the latest STOCK ICS.
Huge memory leak! Launcher has to restart on every unlock barely 20-7 mbs free!! and battery also drains pretty fast, although not when in sleep.

JB vs ICS battery life

Is it just me, or do the JB ROMs, custom, official, just rooted, etc, get less battery life than the ICS counterparts?
I first had a HOX back in July/August, and used only ICS ROMs. So I have a pretty good deal of experience with it, got about 5.5-6 hours of screen on time every single time.
Now, I noticed a drop in battery life on JB when I had an S3, and just hated the drain. I thought maybe it was just ROM related, and moved onto an iPhone.
Now back onto another One X, and it seems like I still get less battery life than when I had ICS, and I use it the same way.
Has anyone else noticed it?

Your battery is probably depreciating and loosing its full capacity.

Probably not JUST you, but from what I've read and experienced you're in the minority. My battery is definitely better on JB.

I've had much better life on JB, at least since I updated the whole phone (not just a JB rom). I can go almost two days without a full charge.

Hmmm, I'll try a different ROM then. And a JB radio.

I ran the 2.20 ruu then flashed the 3.18 ota. Once on that base, I've been super stable with CleanROM and Elemental kernel.

My work phone (my HOX) is running completely stock (has to, effing government policies...) and has had terrible battery life since updating to JB. It seems to mostly be due to maps sucking me dry, which I presume is from Google Now. Maps is constantly waking my device and using whatever data connection it can get, which is why i presume the Now stuff. not sure, seems to be fine when i turn off WiFi, so it seems that the wifi use on google now is problematic. I factory reset the device but seems to still be running the same. I've been losing almost 10% battery an hour when I leave my wifi on with barely any use of the phone . this was never the case when the phone was on ICS. it's clearly some sort of data connection as it relates to Maps usage as i've been seeing high CPU usage by the app and, at times, nearly 50% of my battery life going to the maps process.

Also, just noticed on BBS that the android OS and maps high battery usage may be due to alarm manager...I'm seeing many long awake times for a number of apps. hadn't noticed it as much before because i had booted the device multiple times today. any thoughts here? i know what this app is for and there's lots of info and complaints out there about this process on other phones in the past, but not much for stock JB on the HOX...

I have had TERRIBLE battery life while running Sense JB ROMs, (seriously, incredibly bad), versus ICS ROMs. Tried nearly every Sense JB ROM that's out there and countless different radios. No idea why I'm having this problem. I'm not having problems with wakelocks BTW

It's maps. I don't have Google now and maps still ate half my battery on JB. Only way to get around it is make maps hibernate I've found, but this requires rooting.
Sent from my HTC One XL

Try Greenify. You need root, but it allows you to stop apps from running in the background. It's not a task killer, which are worse than nothing because they run constantly shutting down apps that keep restarting; rather, it uses system settings to prevent them from starting background at all. You can use it on stuff like Maps if you use another app to convert them to user apps. I've been using it a couple of weeks, and it's worked just great.

Thanks. It definitely seems like Maps is the problem for me. BBS shows a number of maps-based apps with long wake times. I charged up to about 95% before bed last night, and am going to let it run down all the way today to see what happens. Will post some screenshots later, if anyone cares.
EDIT: Nevermind, will probably post this in the BBS thread, unless anyone here really wants it.

Same. 2.5 hrs of screen time vs 3.5 for ICS. Same usage.
Viper JB vs Cleanrom ICS.
Stock everything else (radio, kernal)

maybe not necessarily maps like originally thought, though it's one of the culprits. the mediascanner just happens to hit maps a lot, likely due to it's typically-large cache. check this thread, particularly post #42 and the Google response another 10 posts or so later. sounds like there is definitely an issue with the device indexing and it's the same thing that affected a number android devices. my guess is that some people just dont have a lot of media files (or wipe their phones often enough that they dont accumulate much) and dont see as much of the effect.

there's also a link at the end of that thread to another similar thread, found here: http://code.google.com/p/android/issues/detail?id=40370#58

Lol, corroborate.
Idk, I still think it's maps. I don't have very much media (2 albums) and disabling maps fixed my battery life (200% improvement, literally).

yeah, i'm back on this boat as well. maps still has a long wake time i'm seeing location scanner services running so i'm thinking it's a location-based thing. going to let my phone die today so i can get a good BBS log since i screwed that up yesterday. i'm noticing odd dips in battery life whenever the phone wakes up. it seems to stay awake for up to 10-20 mins, but with the screen off. really weird thing is that when i let it sit overnight, there's no spike (just greater than usual battery drain) but it's when the phone first wakes up that it seems to be really draining and staying awake.
