kernel question - Samsung Galaxy S (4G Model)

i have a quick kernel question, i have cm9 rom installed and i did some searching and found that changing the kernel could help with battery drain, so im needing 2 know if this actualy helps. with cm9s kernel my phone only lasted abt 6hrs from doing nothing but txting (i have no apps on my phone except batteryxl/2xbattery. im not using the pro ver as i do not buy apps, so my wifi is constantly turned on even after i shut it off manualy and turn data on), i flashed the team faq kernel and still see abt the same, if changing the kernel does help with battery life, what kernel would be the best 2 use? and if possible could you link me to it. i have searched the sgs4g section for kernels but havnt found many in the development forums.
(if a question like mine was asked/answered b4 i am sry 4 reposting, as i am still trying to figure the best setup 4 my phone that will last atleast a full day or longer from just txting)

Atm there aren't any ICS kernels besides those two. You can try to under clock to 600 or 800 MHz to get a little more screen on time. Its either that or go to a GB rom with known good battery life

First off, have you read some of the other threads on battery life and ICS?
Second, what do those battery apps actually do? They may be doing more harm than good. BetterBatteryStats will provide insight into why your phone might be draining so quickly.
Third, turn off the WiFi! Not clear why you have it on if you're only texting.
Sounds to me that if it isn't one of those, it's new-shiny-toy syndrome, or cruft from flashing (if you believe in gremlins)

Battery apps don't do anything to improve battery life anymore. They were needed back around froyo and earlier but not anymore

ive seen some improvment with batteryxl/2xbattery running, after calibrating my phone battery its showing its lasting around 18hours, as for my wifi im always home so its connected 24/7 for the other apps that are updated, i will try buying a new extended battery in the next few days and see how that works

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.

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?
Did you try wiping 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.)

[Q] battery stuck at 96.. before would go to 100

Well has the title says.. i use to b able to charge to 100% some 1 month back with the screen on and WiFi tether on.. well updated to latest matrix kernel charges only till 96% so is it implemented in the kernel? or is my battery miscalibrated or something like tat?
So lets see.... you singled out that this began after installing the latest matrix kernel, yet you didn't think to post in the matrix thread to see if this is happening to anyone else who installed it? Considering your target audience is in that thread, you would more likely find your answer there.

well did flash talon and was using original miui kernal has well.. same thing it wouldnt charge past 96.. guess should have mentioned... but if u could help me out is it implemented in the new kernel or just my mobile is miscalibrated
Anyways got my answer its bcoz of Battery Life eXtender (BLX)..
Heh always this battery thing. It's healthy for your battery to go to 95% only, same as it's better to not fully drain it. Thats exactly why there's no numeric battery indicator, ppl would be confused.

[Q] Battery Life w/ BM ICSv5 and Franco Kernel is GARBAGE!

Please read this before you go crazy on me saying I haven't searched for this because I have. I've updated from every ROM of ICS thats dropped after reading up on them and the fastest and best working everyday ROM for ICS is BrainMaster's ICSv5 with Franco's Kernel 11/25. I haven't tried 11/26 but I've read the colors are much better on 25 and I believe it because its the best my screen has ever looked. SHARP!
So here's my issue. I want this as an everyday user, and I'm sure it can be. I just need to know how to set up the battery so that it lasts longer. I just restarted my phone and cleared all the battery info. Before I unplugged it at 6:30pm EST I had 91%. After very, very minor use (looked up the number for Home Depot and downloaded Amazon Market) I got back home at 9:30 and my battery was at 39%. Thats 60% in 3 hours. Thats terrible. How can I adjust the batter life? Can I use NSTools to do so or do I need to change code? I don't want to change the kernel completely because the colors truly are AMAZING with this version.
Please let me know, and thank you in advance!
Best regards,
Tula
Well, which app or function specifically is causing the drain? Did you look at the battery usage? Were you in an area with poor signal reception?
Before you trash a rom and kernel with a poorly conceived thread, try troubleshooting the problem.

For what it's worth, the only time I've gotten that kind of battery life is when a NFC process decided to start and run nonstop. No idea why it was running (particularly since I don't have Wallet configured), but since then I keep NFC disabled.
When that happened it was similar battery life - lost about 70% in 3 1/2 hours.
I never once trashed the ROM or the kernel? What are you talking about? Before reading into something for more than what it is you should take it for what it is. I don't know what the problem is, everyone else seems to be having a great amount of battery life. I'm asking on here, in this forum, because I figured someone (maybe a programmer who knows these things) can tell me how to "properly" config it. Idk what the deal is with it but I was looking for insight. I love the ROM and the kernel and I do believe I stated in the post that I wanted to keep it as a daily user. SO, either you can help me and teach me how to fix the problem or teach me to give you what info you need or do me a favor and don't waste my time. I'm looking for answers or suggestions. Not accusations and negativity.
"Poorly concieved thread!" Whats "poorly conceived" about it? The fact that I reached out on a FORUM and asked for HELP? Go comment on somebody else with that bullsh*t.
Reread your thread title; calling something "garbage" is not trashing it?
Reread and answer the questions asked in post #2. Nobody can do anything to help if you don't provide basic information or perform rudimentary problem-solving procedure.

Well man what i did with mine was calibrated the battery which means charge the battery completely then boot into recovery wipe battery stats then unplug and reboot then use it for 5 mins then charge fully again then unplug and drain completely till it shuts off on its own then fully charge again and it should be calibrated.. sounds like alot.. i kno lol but trust me it works and then if ur battery life doesnt extend after that (which it should) then i would look at what it is thats using the most matter (menu>settings>battery and go from there.. also make sure u have all the apps that will allow u to move to sd moved there it keeps them from running in the background and also make sure ur screen brightness is set low.. i took my auto brightness off and just turned it down just bright enough to see.. i know the colors looks fly like a bag of skittles when u got the brightness up wit franco kernel but it kills battery lol. hopefully that works for u pimpin and sorry for the novel lol just wanted to give u a few options to try.
JG & Freshie, thank you. And Braneless, you must be Braneless, because if YOU could read you'd see that my title says BATTERY LIFE is garbage. Not the ROM or the Kernel. BATTERY LIFE!
You seriously are 0 for 2 with trying to make me look like an idiot. I guess thats why you have almost 600 post and only 50 some odd thanks. Because half the time you're just bashing people trying to make it seem like you know it all when you can't even read a title correctly.
As far as the battery, I followed your instructions JG and also I started from the beginning and deleted all installs and reset to factory. I then installed each ROM from v1 all the way up and now EVERYTHING works and I got almost 2 hours out of my phone today and used 9%! WHOOHOOO!
Thanks again to the read Googlers who want to HELP OUT instead of trying to make people look like idiots.
AWESOME!
I had this problem too, but in my case it was the Google Wallet app. It drained the my battery in like 4 hours. After uninstalling it, all went back to normal.
Now if you said battery life on a rom kernel combo was FANTASTIC.
What would that imply? Thanks guys etc.
You go through all the trouble to make the thread but not spend a couple seconds to check what actually used up the battery.
Omfg this thread title just made lol all over the place haha

I'd recommend trying out Nexus MV 2.xx its the best daily driver so far. battery will make it through the day, i used it for a quite a while. Now trying out the alpha 13, but will go back to MV if this doesn't cut it. I tried BM too but didnt notice too much difference from Kwiboo and the earlier CM9 A 11.

Battery Life

Have one of these, rooted, stock rom on Rogers (LTE).
The battery life seems inconsistent... Some days it seems fine but days like today with 11 hours off the charger, with the two highest battery culprits being android OS (46%) and android system (16%) the battery life is already at 26%.
Other days when its on my desk it uses nowhere near as much...

You talking about the TMo version? I did a search and I cant find a Skyrocket or Rogers version of a BeastMOD ROM.
BTW I get have been getting 34-37 hrs @ 20-15% on the BoneSTOCKeteer-v1.0 ROM with med to light use. Your mileage may vary, but stock ROM only lasted a day with the same use.
edit: the more you play with/use your phone the faster the battery is going to peter out no matter the ROM
I noticed that wifi has a big impact on battery life. I hit about 50% of battery life with it on in about 5 hours but with it off and moderate use I can get 2 days use.
Just a thought and I froze lots of the SNS syncing apps with TB. I dont use those since i use another program for FB.
I actually like the ATT Smart Wifi app. Shuts down wifi when not in use. I think the free version of Juice Defender doesn't do that.
I have now owned my 727R for 6 weeks, coming from an iphone 4. I am finding the battery life inconsistent from charge to charge and anywhere from barely adequate to downright poor. Maximum I have ever gotten was 26 hours with minimal use and minimum has been 10 hours with minimal use.
I have installed and use Juice defender, and have looked at a variety of apps such as cpu spy, cpu hound, traffic monitor. I have turned off notification as much as possible and all other tricks under the sun.
My phone does not seem to go to deep sleep often and a lot of times it shows as awake even though the screen was off for a while.
The straw that broke the camle was when I cmpared notes with my clleague who has a Galaxy S (I know, no 4g, no LTE, smaller csreen). But he is getting 90% battery life with wifi and bluetooth on after 7 hours 15 minutes (minimal use). In the same time period I am down to 60% with bluetooth off!
I am not planning on rooting the phone and using custom ROMS or Kernels right now.
What gives? What do I look at to improve battery life?
Thanks
i notice with out a lot of changes i get horrible horrible battery life. but with a custom rom like quick wiz. i turn screen down. wifi off. under clock it and use a battery saver plus task killer i get two days moderet (use
Sent from my SAMSUNG-SGH-I727 using xda premium
I would suggest since Roger stock rom sucks the life out of the battery to root it and use faux123 kernel and Gideon's script to under clock it. Im using at&t stock rom rooted and faux123 kernel and I haven't had a bad battery day yet.. currently 12hrs moderate use 73% still.... not bad at all. Give it a try.. its not like it could any worse lol

It looks like this isn't available for Skyrocket.
1) Does it work like it should, and does it save battery, or is the battery savings negated by other junk running with it in the background? Reviews seem very mixed.
2) If you got it on a SR, how? Would pulling the APK from another device work?

I hated my skyrocket when I first got it because the battery sucked. Never could make it through a full day of average use. I did a search, found out how to root and install a custom rom and now I love it. I can go a full day and still have 20% left. All I can recommend is rooting and at least remove bloatware. I've never seen a single skyrocket user happy with their battery life on stock. Maybe sell or trade it for another iPhone.

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.

Try or buy Better Battery Stats. There really isn't anything that compares, either for features or support.

Have you tried clearing cache, clearing dalvik cache, then fixing permissions, rebooting and waiting at least ten minutes after reboot? That is what always fixed my "Android OS problem"

Yeah I've tried it all, and now I have replaced my battery and still getting the random huge battery drop offs. Tonight I'm going to GR to CM9 and then to codename and not restoring my apps

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.
