The battery life on my stock ICS LP9 is horrible. I was thinking of rooting it and installing some custom Kernel to improve battery life. Can anyone suggest which kernel is best for battery?

For better battery and stability use SpeedMod 3-3.
kernel and modem combination.
speedmod k3-3 and lb2 modem works fine for me.
This kernel works on Rocket Room V7??
Do you have to root the phone first?
Before applying Speedmod 3.3?
thanks

Yes it works very good on RR v7 tried flashing franco kernel v6 but that gives random reboots v5 eats lot of battery,(i guess due to overclock) so I flashed this kernel so far its going very good.
Notecore and speedmod kernels are the best with both performance and long battery life

notecore is stable and give a day long battery and gives you custom bootanimation+15 toggle+call recording and much more.it is double check for emmc brick.
speedmod is superstable and give a good battery life and gives you custom bootanimation+15 toggle+call recording and kills useless things.
NOTE-1. Dont use oc as it will heat up your device,better to go for std.
2. downgrade to pre-rroted gb rom,dont take a risk although they are safe to wipe,but still first downgrade.
Both the kernels give you better battery life
But for me its Notecore
Hello,
I made a lot of tests.
today, here is my config :
samsung ICS DDLPA. rooted, with kernel SpeedMod K3-11.
with stock kernel, I had good battery life.
with SpedMod kernel, I have better battery life.... when Note is sleeping.
I also had installed Lightning launcher. is better or not ? difficult to tell the difference it is slitghly the same.
to be honest, when I read a movie, listen music, go on internet, it use a lot of battery... which seem to be normal.
today, with medium use, I can have 3 days of battery.
with more use of the note, I have 2 days of battery.
Medium use is : no video, New republic (RSS reader) for around 1 hour, several SMS, some phone call, Internet (around 30 minute), one or 2 time google play, 1 hour reading an ebook in the night (black background, white text)
more use : Add Music, more internet, time spend in tweak the parameter of my launcher.
without SpeeMod kernel, I could lose around 15% to 20% of time listed above. no much.
I hope it helps.
Olivier
The latest speedmod is the best kernel for the battery...
I just tried speedmod and while listening to music via bluetooth and playing solitaire, my battery drains 4% per 10 min.
It's this normal?

bluetooth drains like crazy, as well as playing games, so yeah. Youre better of using normal wire headset.
4% per ten minutes is 24% per hour, so approx 4 hours screen on time is actually pretty good, very good even. Cant believe that with bluetooth on.

Speed mode 3-13, best for battery.... But notecore is smoother....

Thanks for the tip, I'll switch to wired headphones and see how that goes
Not sure if it had made a difference, but I did removed alot of the stock samsung apps such as samsung app store, samsung push service etc and also changed the modem to XXLRI, which I find is better than XXLRK.

Omg... try to finish the battery , leave it off on charge and in the morning when the charge is complete, go in recovery and do a wipe battery stats.

Yeah I have the same issues, many of us do, dunno from where that is, kernel or rom or android 4.0.4 or the lrk base??? , deep sleep is perfectly fine, but once screen is on, it's ridiculously high..

Flash the SpeedMod kernel and see if this improves things for you.

I have same exact problem guys i tested speedmod both std and oc version and speed mod too and nothing much change but speed mod drain too fast

Alternatively you could take the overclocked NoteCore kernel and underclock it.
The kernel is undervolted, so disabling higher processor frequencies will give you the benefits of undervolting and the benefits of underclocking.
I.e. low power consumption and low temperature.

Its not a 4.0.4 LRK issue. I was running a rooted stock build and installed NoteCore kernel without any issues. When I flashed Rocket V10 it was only then that the battery life became crippling. Shame, I love Rocket and the tweaks but guess I'll go back to stock!

Could u help how much underclock and undervolt....
Sent from my GT-N7000 using xda premium
Take a look at the NoteCore thread in the development section for the undervolt details.
The overclocked kernel is undervolted.
Install the overclocked kernel then use something like Tegrak to limit the processor frequency to 1400 or 1200 then you will get the reduced battery drain of using lower voltages and lower frequencies on your processor.
Don't change the undervolting set in the overclocked kernel add this had been optimised.

I don't think it's the kernel's fault for the battery drain.. I think it's the modem..
I have been using notecore with all the touchwiz roms no battery problems at all
RR 10 with NoteCore 13
Just installed NoteCore 13 8hr ago, and plug the power cable for charging. Still plugged now, but the SpyCPU report shows that during the past 8hr, the phone didn't go into deep sleep (while I was ) , but it stays at 100Hz.
Will unplug now and go to work for a day. See if I can get a usage report after work.
Cheers
Yep, definitely faced the same problem, which was the reason I switched to Classic Rom V4 (because of the newest firmware) but actually, though battery life is better, it is still worse than with AlBA v4...I haven't been able to determine whats behind it...

After a normal day usage... The battery drain is still heavy... When screen on, the percentage dropped around 1% per a min or two.
Dunno why... Deep sleep state is ok.

2nd of RR10 with NoteCore 13. The screen-on drainage improved. I read my whole travel time (around 1.5hr) on newspaper via 3G signal, and the battery went from 100% to 81-82%, which is acceptable for me.
Again, Deep sleep works perfectly.
I left this good rom because of this, deep sleep ok, but when the screen is on, too heavy battery drain. same with 2 kernels, should be another reason.

I tried with notecore and speedmod. I have used RR10 about 3 days to have several battery cycles. but I felt a big battery drain when using the note, even at low brightness, with nothing strange in CPUspy or BetterBatteryStats.
so I switched to JB liquid. Yesterday night. I would not say it is better for the moment to be honest. New rom, new kernel, not even a beta, so hard to compare, but you are right I feel the same today: high drain with screen on.
(but whatever the battery drain, with palm rejection available on CM9/10, I will switch again to a sammy rom)
I really cant seem to find a way to lower the screen on battery drain , its ,horrible ,
been on latest std notecore and speedmod , and with both i cant seem to get more than 2:00 - 2:30 hours of screen on time & basic use (in total of 10 - 12 hours ) , deep sleep is perfectly fine with 1% loss per hour (sometimes even less !!) , but with the screen on , battery just goes bursting -1% per minute........
we do need our devices to be used , not rested on deepsleep the whole time , otherwise this defies the whole concept of a "smartphone"....
on GB it was very good ,it got worse when Samsung introduced ICS (but was manageable) , but now on 4.0.4 , its just horrible and unacceptable!!! dunno what kind of testing Samsung does before rolling out an update...
sorry for the whole rant and rage post in there , had to speak it out cos im struggling here..
would be highly appreciated if someone can help or a suggest a 4.0.4 rom with a "reasonable" screen on drain... im even considering going back to RRv7 (4.0.3) cos as far as i remember i was getting good battery out of it (deep sleeping and screen on was great there)
cheers.

Try take out your battery for one min. and put it back again.
If not take out/put back battery helps, then download "battery calibration" app from Play Store, fully charge your phone, and run the app.

Hi,
If you still facing the issue, try to see what is eating up your battery. Best way to analyse the situation is by installing an app called 'Better battery stats'. Its by a XDA member and if i'm not mistaken he offers it on XDA as free download. Try to see what is causing partial wakelocks and kernel wakelocks (your phone should be on deep sleep mode for the majority of time). Try to see what MHz is your processor running at (it shouldnt be in the 1400 range for too long unless you are playing some heavy duty games)
Also try to search for threads on 'wakelocks' on XDA to get more details on this subject.
I have experienced close to 10% drop in 1.5 hr in stock ROMs and around 15% in five hours on CleanNote ROM in idle states with lots of background apps disabled.
hello xda
i was on GB 2.3.4 rom (surface JVR) and battery lasted two days minimum (with normal use)
for some unknown reason i couldnt get past "scanning sdcard" so i installed Helly Bean,nice new features i admit i did not see any bug, but battery loses 1% each half hour (when phone is sleeping). using it i lose like 30-35% each hour. everything works including BLN but battery drain is too damn high
on my previous GB rom battery use was maybe 5% each day (when phone was sleeping).it had unbeatable battery life even oc'ed to 1200.
what JB rom do you guys suggest has the best battery life? maybe change kernel? change governor? another radio? from your personal use; what would you say? thanks
Hello there,
I have Paranoid Android on my i9000 and the battery life is just cool, just try it
(If you see battery draining, just turn off 3G when the phone is sleeping, so it would be Awesome)
I hope it helps

battery life seems ok now, still not as good as on GB but not a drain as before.

Battery seems to be a worry for me? any suggestions?
...
I have been trying a number of ROM over the last three weeks and so far the one that really stands out in performance and notably in Battery life is [AOSP][ROM][4.2] JellyBean 4.2 PREVIEW (20121125) by pawitp that I have been using for the last three days.
As always I have both Juice Defender (free) and Go Power Manager installed. Juice defender set to aggressive and Go Power Manager set to Super Saver. The phone (i9000) is used for calls and sms for the most part as it is a business phone.
I have only used 34% of battery since Wednesday morning till now (Friday afternoon) - something that even with Gingerbread was not possible.
Am about to upgrade to the 30112012 version this weekend. http://forum.xda-developers.com/images/smilies/good.gif
Hi, i'm using the GamerzROM with Semaphore Kernel, but the battery drain is too much. Yesterday, i used the wifi for 55 minutes and the battery goes from 100% to 70%. I think that is too. How can i fix this problem? Another ROM, Kernel or else?

After 12 hours on battery and more than 2 hours screen on most of that on 3g battery is on 64%.Saurom rom.
i think that you need to buy the new battery but firstly check if your is broken in settings -> battery make there screen and upload him here
