The first 2 weeks of using my note XEU KKA version, the battery life was ho hum, OK but not great. Then all of a sudden it doubled - consistent, really good!
I rooted and flashed LA4. The process worked fine. But now my battery literally sucks really bad - as in immediately after rooting and flashing you can watch it go down down down. Any ideas why?

what kernel are u using... theres a kernel battery comparison thread.. am posting from a mobile so will be diificult to post the address... by the way my note's battery also sucks acter flashing it with abyss kernek and rocket rom ..both latest versions.. can see constant drips while using inyernet or playing games... n 85 per battery is consumed by display as can be seen in battery stts
Try resetting the Battery Stats via cwm. I'm on XXLA4 and Abyssnote its fine for now, but i need to test more.
Sudden battery drain is usually due to:
1. Kernel issues. We all have the same device, and one would expect that all our Notes behave the same way with a specific kernel, but the fact is they don't. Don't ask me why, electronic gods have some funny ways and quirks. So, try using different kernels, and see how they affect your battery life. Flashing them is a piece of cake, just read the instructions carefully.
2. Rogue apps. Stock ROMs are full of crapware that like to reside in the memory and suck up your juice. Try searching XDA Note forums for the list of removable system apps and get rid of those you don't need. That is easily done by using Root Uninstaller or Titanium Backup.
Hope this helps.
I am using dolphin browser battery saver apk. it is very usefull. Especially it is turn off wifi under sleep mode and saving battery.

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.

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.

My suggestion would be stock gingerbread with speedmod kernel k2-12, i used to get around 4 days with normal use.
That sounds nice. Do you have heavy use of yout phone? Or only deep sleep all the time?
Sent from my GT-N7000 using xda premium
I use it for playing games, little music, calls and messaging. Sometimes connect to Wi-fi. With the same in ICS i get around 2 days.
okay thank you i´ll try. :fingers-crossed:
to set expectations straight, expect thought about 4.5 hours nonstop usage on gb with speedmod kernel.
4 hours on ics with speedmod
alk stock dont expect more then 3 to 3.5 hours.
you only get 2 days if you dont synch, barely use phone and are in good reception area with data switched off always.
Note general tips which can be found in the 10000plus threads about battery drain and how to analyse deepsleep issues

I don't know whether you like gingerbread roms or not , but till date the rom with which I got maximum battery backup with modeate to heavy usage was CheckRom Revo HD V6. This rom never lags , best battery life , and good speed .
If you are Gingerbread hater and ICS lover , then you can try Rocketrom v7( very good battery life with the included kernel , and would be much better with Speedmod Kernel (latest version) ). And then you have CleaNote V2.30 ( V3.0 has bluetooth glitches but its faster , if you are bluetooth user i would suggest you to stick with V2.30 ) , I personally love CleaNote because it has stock look and very fluidic :good: and as the tagline says 'You dont want any theme forced down to your throat '. KingDroid are good at speed but many have reported few glitches with it , you may try it if you like ( I dont like KingDroid , its sth personal ). If you hate Samsung's bloatware then we have Cassie's XtraLite rom for your rescue :cyclops:. Its a good rom too .
Well finally to end , I use cyanogenmod 9 and i update it everyday and with each update it gets more fluid and responsive, fast , smooth . i just love cyanogenmod9 ( waiting for cm10 ).
ParanoidAndroid are for ppl who love fun , who want to showoff their phone , the ability of their phone , the sweet hybrid interface of their phone , its for geeks :-0 .
Make a choice or try all of them :good::good:

I am using CLASSIC V1+15 toggle with MOD V1 which is ICS 4.0.4, and I also updated kernel to chainfire LRG, which is more stable and smooth, battery life is excellent comparatively to all other ROMs so far.
Which is around 4% drain per hour, I have (facebook, wechat, LINE, mitalk, whatsapp, email, exchange service, maps, mixed chinese input, make your own clock) running and leaving it on idle.

For the past 2 years of beeing a S galaxy user, I've quite looked for best battery life at top performance. Most of the time, battery life is no longer measured in "days" of usage , like we used to do with our Nokia phones. Nowadays, you ten to look at display (screen on) time , CPU profiles, and also connectivity patterns.
You can think of battery life as a factor of the above mentioned, however I think that display time is the most important parameter related to battery life. CPU profiles, connectivity, tend to work only when you have your screen on, and from my experience, you tend not to extend your usage time by more than 10-20%.
So as a conclusion, I did not expect a specific rom / kernel configuration to offer more "screen on" time but to offer a more faster way to do my tasks therefore I did more tasks in almost the same display time.
At the end of the day, it is more important how you USE your device rather than finding a "magical" combination that will increase your battery life.
KID + SpeedMod
+1 for GB (i was using checkrom but i'm sure any gb rom will give similar effects) with Speedmod.
If you make setcpu to 200mhz on screen off, i find it uses almost no power at all when it's on standby.
Like it was on 77% when i went to bed.
Woke up in the morning and it was on 78% (i was like lolwut).
Yay for setcpu.
But seriously though, any GB rom will give you considerably more battery life than any ics rom.

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.
