I know how to use a search button, I have been on forums for a LONG time.
I also know how to use google. That being said, I have done hours (literally) of reading, learning, and attempting to choose and run the best kernel for my phone.
I would like some personal input from community if I could.
I have looked extensively into Imnuts and Nemesis2all's kernels.
I want one that will give me a tiny speed boost, but more so one designed to give me the longest battery life I can get while still containing the ability to run at a decent enough speed.
Any input would be great.
Edit-I guess it would be nice for you guys to know as well, I am running Evil Fascination 3.6.0, with the black mods =]
Ive heard both good and bad between these two kernels. Everyones phone is different and results will vary. Imnuts has a fixed undervolted setting either 100mv or 50mv but the limit is 1000mhz so theres no overclocking. Nemesis' OTB it is customized through voltage control app on which frequency steps you want to undervolt and you can overclock the kernel past 1000mhz for faster speeds. Ive also had good experiences with Comavolt (undervolted by -75mv) on SC 2.9.2 but I havent tried it out with CR 2.0 yet. If you arent into messing around with the voltage settings too much go with Imnuts or Comavolt. I suggest giving 4 days on each kernel with a battery stat wipe prior to see which one to settle with. Hope this helps!
Thanks man.
That's the kind of reply I was looking for. I think I am going to try out comavolt for a few days.
And do a full battery stats wipe, I may try and dig and see if I can locate an app that can log, and show me in much more detail where my battery life might be going, rather then just the silly android one in our menus ( I am fan of detailing when it comes to performance. )
I will post up in case any one else has concerns or questions whether to which to choose. Or if anyone else has an personal inout I would gladly take it into consideration.

CPU Spy and Spare Parts are two good apps for the kind of info you are looking for on battery usage and more.
Also, being that I am on evil fascination.
IS it considered to be more a AOSP rom, or is it something else?
And give the two options pretty much explained to me, does anyone know if theses are STRICTLY zip? Or can they be had in an ODIN compatible format as well, (hate flashing from sd card if I don't have to.)
I had been using Comavolt with Comm 1.3 until I went to PBJ with the Comm 2.0. I will see how it is with PNJ. I had very good result with Comavolt; so I hope that helps out.

I am running otb. OTB lets you change the clockspeed and voltage. Effectively, you can undervolt, overclock, or both in whatever combination. I have a voltage control app on com rom that makes it easy. I'm not too aggressive, and I've not had a single issue out of it (performance or stability).

Personally, I believe that there's no point to overclocking your phone other than being able to say "my phone is overclocked." I've always gone for battery life when choosing kernels and I've never had performance issues. I've had good experiences with all of imnuts' 100-mv UV kernels. I just put SetCPU on conservative and forget it.

i'm running stock, debloated ED01 and nemisis2all's OTB 1.6 on stock settings flie for my phone and the battery life is great for me. you can tweak the clock speed and voltage really easily with the recommended voltage control app that's free from the market.
I have used ninphos 2.04 and 2.05 and alot of chainfires kernels (kg2 kf2,kg3 and more)
I have noticed alot of diffrence regaring batterylife....between each one...I THINK chainfires gives best battery so far and ninphos 2.04 alot better battery than 2.05 (maybe its the BLN support that uses more battery even if BLN is not used)
So now I want a thread were you recomend the best kernels for batterylife!
So what is the your opinion?
Does a kernel really have something to do with battery life?
The kernel ought to be one of the major 'invisible' factors. It is always active, and has an impact of the timing of everything else that happens on the phone. Particularly if there are bugs which have a detrimental impact on battery, the kernel might expose or hide them. That's not to say that the best kernel will necessarily give best battery life.
I don't think it's BLN if not used.
I did some tests and when the lights are not flashy-flashy the phone enters deepsleep as supposed to and my battery life hasn't gone done noticabely, if you don't use BLN at all there isn't even the BLN service running in the back, so even less to worry about.
Ninphetamin is aimed at performance IIRC, so that could really make a difference, CF-Root is pretty much stock kernel + some initramfs mods, so should give same results as a stock kernel.

Maybe you are right, but I experience better battery in 2.04 than 2.05.
Anybody have tried speedmods kernel? Does it have good battery compared to CF-Roots kernel?

Imo I think you are correct since the Kernel is the base for everything while Android is running.
Thus, you better flash to a stable/faster kernel in order to achieve better battery performance ?
I really don't have any experience with the Kernels out there, only flashed to Chainfire CF-root, though I would love to hear opinions about ppl that used few different kernels and tell their thoughts about it.

I wrote a little bit in my OP, but I write again, ninpho is really good, very fast and pretty stable...CF-root I see is better battery and more stable but a little slower...
those two I have tried...anybody that have tried others are welcome especially speedmod kernel as I'm thinking about flashing it

Thanks for your reply mister.
I have a question going on in my mind as this is about kernel, well I also was rooted with CF kernel but lately I flashed Ninphetamine 2.0.5 kernel, only to use BLN, and I have root too, now afaIk, I can't have two kernels at a time, so may I know how I have root still when I've flashed with Ninphetmanine kernel and I have both BLN and Root altogether?
Pardon me if it's a stupid and so called 'noob' query but I'd really like to know this.
Regards.
different kernel does different things.But if your phone has already been rooted,I thought root will stay in your system,after your flash N kernel,you can use BLN with root.
That's what I think,maybe is not true
I've tried several kernel. one of my favorite is ninpo 2.0.5. battery life look good and it run faster.. angelom kernel also good but i've got issues on angelom 16 and 18.. phone run hot when using WiFi.. but angelom give me the best battery life when it come to idle.. but drain fast when i'm surfing..
will try speedMod kernel.. could some one give me some review on this kernel?
Thanks in advanced..
Hi, I am a noob so please help us out?
Flashed my SGS2 (first time android phone)with CF Kernal KG1 to get root, and bloatfreezer to freeze Samsung and Optus crap as per lists on XDA. Rather than getting better battery life I have noticed a quick drain on the battery. Namely Android OS which uses about 50% overnight.
Is this normal? what can be done?
I dont see much of a difference between CF-Root kernel, speedmod, and ninpethaine 2.0.2 - 2.0.5. Except speedmod doesnt allow CPU monitoring, overclocking and undervolting.
removed 10 char

I did try speed mod and honestly, I feel ninpo give better life than speedmod. Well it could just be me but I just tested it at average usage...So, yeah...

Well honestly, if I remember clearly, there is an OS bug currently. However, why don't you try on other such as KG6 or KG3?
Also, did you install anything middle of the way? Could be an app or something?

Hi guys Again :cyclops:,
I'm just asking for good ROM with long battery life (Battery extender Kernel) , faster ROM , etc.
I've looked too long On YOUTube, GooGle , XDA-DEVELOPERS Forums , ...
But Finally I decided to make a New Thread for a LITTLE HELP:angel:
My requirements (approximately):
1st*Long Battery Life
2nd*Memory Booster
3rd*good Gaming-no lagging
4th*good Appearance
5th*not to be Like ICS
6th*No use of Launchers (Something really custom)
As I told you I don't want to be just like these parameters , that must be approximately :laugh:
Thanks for reading
Hmm. They're too many. I suggest you try them all and pick which would suit you. I would suggest Myth2, Xperiatized, Stocklite etc etc since you mentioned Battery Extender meaning it will be stock.
The best would be to get a ROM with long battery life and maybe combine it with super v6 charger for the sake of memory.
Gaming without lagg, not gonna comment on that.
And the last two requirments can be done seperately, "good appearance" is a subjective opinion.
I'm using apocalypse rom, but i cannot say that it gives the best performance of all of the recent roms out there since i havent tried the others.
Go to a bar and ask which drink is the best. You won't get your answer. Same applies to ROMs.
I'm closing this one.
Okay. So I am currently running shostock3 on my sgs2 with siyah kernal. I read the article from zedomax on galaxys2root.com that it has very good battery life and very stable but when i am running it, I have terrible battery life and i am currently underclocked or whatever the word is. Is there anyway to fix this?
My advice, run SHOstock3 as it was released. It runs great as shoman94 dev'd it.
...and stay away from that web site u mentioned.
Stick to XDA. Period!

Most people get really good battery life on SHOstock3. Just search the SHOstock3 thread for the word battery to see what I mean. If you're not getting good battery life, you need to find out what in your configuration is causing the problem, and fix it. There is a thread in the general section started by Entropy512 that you should study to help you identify where the problem is.
I was on GB ShoStock for a long time thinking ICS and JB would never leave me satisfied on battery life.
http://forum.xda-developers.com/showthread.php?t=1353513
Finally came to my senses and tried out ShoStock 3 and have never looked back. To make it short the best Rom Ive ever flashed for any device I have had in the present and past.
You definitely have a rogue app killing your battery, find out which one it is and uninstall.

Sorry you have battery life problems.
I have been running Shostock3 since it came out (it's version 3.02 today!), but I also been on and off at least five (wow can it be that many?) JB roms on my SGH-i777 (won't even mention the # GB roms here!). After trying many, I must agree with the other posters who state that this rom delivers very good battery life when compared to stock and when compared with other custom roms.
Lately, it has delivered the best battery life I have ever had on this phone using any rom (although SlimBean JB provided very very good battery life for me recently as well! Also UnNamed was great for battery life in the old GB days )
I followed the recommendations made by creepyncrawly to read Entropy's (& others) battery notes/faqs. They provide some really good background, some with that typical "XDA flavor" (read technical!. That material, plus some more plain old simple user adjustments to how and what I use on the phone have improved my phone's battery time; and it might help you as well.
It really boils down to the fact that each phone user loads different apps and our usage patterns vary.
Assume that you've flashed it and let it settle for a few days and several recharge cycles. After doing this you can see what YOUR "norms" are. They may be good or bad, but that's the baseline for you with this rom and with the apps and usage pattern you have.
(You can tweak voltage and speed (well, not speed on SS3!), but my experience has been that the more noticeable changes will be by adjusting your pattern of use, or doing the "hunt for the app" (or apps) that are burning down your run times when not in use.
Not many here seem to like or do this, but I would also try one of those "help-you-with-battery-use" apps --like juice defender (Ok, I get that many here seem to think it a waste, but it really did help me --a little-- when I used it); or get DS Battery saver (a bit more aggressive and noticeable, but you also notice the lag while you wait for things to turn on when you want them).
Actually, these may not be precision solutions, and don't focus on your specific phone app use, but they do work in a macro way to slow battery use and simply working with them for a few days or weeks will provide you with a better a sense of what the heck is going on under the plastic; they will cause you to look at what you have/run and when.
Oh, this includes using Better Battery Stats, which is fine for reporting out exactly which the apps behave --or don't-- and by how much and when. I'm not slow (well, that slow but it frankly, it took me quite a while to figure out what I was reading in the BBS readouts and what they meant! (Now, after a year+ or so of using it, I don't even have it loaded, since I've done the fiddling I need --and BBS, plus those other battery apps, helped me to figure out what apps worked well, what apps I was willing to sacrifice battery on and what apps were useless and should be tossed.)
Finally, some roms just don't work for people! So it's not worth the frustration chasing something you may not be able to achieve with this or another rom. (You probably read how individuals have problems that you don't -yet, you run the same rom and the same phone! That is our world. So, too, you will read about some who make amazing claims on how long they continue on one charge. Some are pretty amazing, and some may even be real
My final five cents would be:
#1 run the rom a couple of days, get a baseline. Then switch from Jeboo kernel to AJK's latest for TW (I think it is 1.25ss, but I really also had great results from 1.48s) and run it a few more days. They were pretty much even for me, but others find one or the other kernel makes a real difference!). Compare after doing the same activities through a charge or two.
#2 If your battery life remains "poor," note what poor really is (ex. how much screen time? and how much total run time prior to getting to zero or 10-15%? ...something like that).
#3. Then get BBS and one of the "automatic" battery-saver programs and work with it for about 4-5 days and that many recharge cycles. See what your norms are but do it for the same type of usage!!! If better while using the battery fixers, then you can work at picking off the app or apps that are sucking your battery more than you want. Not as tedious as it sounds. Of course, staying with a rom for three weeks might be a challenge :laugh:, but this is a nice rom to work with.
#4. I don't think you will need to under-volt to get good BL. I wonder if your phone is stable in doing that? Or, does it induce additional lag? That might be a high price to pay for more run time. (You could compare the UV results with your "norm" as well!)
#5. Finally, we are on Galaxy S2 Sgh-i777 -and can change batteries all day long for not so much per battery! It is not elegant, but it works. (Done it myself several times -even with good battery life).
Good Luck!

I have already directed you to the only alternate kernel that is going to work with Padawan. I am definitely no developer, but it would take a lot of effort just to extract those little options, not to mention the permission of the developer, and it would then most likely have to be installed into another kernel that could be compatible with Padawan.
I am not sure what it is that you are so intent on having those options for, I am sure you have your reasons. not sure that anything else is going to give you better battery life on a 4.1.2 rom. it seems with the progression from 4.0 through 4.4, the battery life is going to diminish a bit with every evolvement.
can I suggest maybe you try Black Jelly. the different rom may provide you that option. if not, Blownfuse has an alternate kernel list in that OP which was designed specifically for that rom.
good luck

My friend, its your phone. Out side of the governer and scheduler, battery life is the only feature you are bringing up. What kind of user are you?

Various roms are going to provide various results. And no 2 devices are going to react the same. I know, folks have said this before, so sorry to repeat.
For what is may be worth, here is my rundown
4.O ICS ... most stable but may be lacking in some features
4.1.2 JB ... touchwiz based, the most stable JB your going to get
4.2.1 JB ... more features evolving into, but most unstable. Some able to control with alternate kernel. Battery life dwindling.
4.3 JB ... increased smoothness and improved stability. Still able to control with an alternate kernel to a certain extent. To me it started to become like medication. The phone seemed to build up a tolerance and stability would decrease. Decreased battery life.
4.4 KK .... did not have a problem with stability, but battery life has really suffered as is the complaint of many.
No rom is going to be 100% perfect. It is more of what can you tolerate for an inadequacy.
I love my music, I FB quite often, I'm on XDA several time a day and I have been catching a few minutes of Youtube.
My phone ran ORGASMIC on Padawan and I did enjoy Hellybean also. To me, battery is like gasoline, nobody is getting any better than me. Everybody pays the same at the pump. You can always get a Ravpower battery 2700 from Amazon for $8 and many swear it increase battery life immensely.
Wow, did I go on and on or what?

I would just take a few for a test drive then. if you had a problem with Padawan and random reboots, then my guess is you either had a bad download or your not flashing clean. a dirty flash is going to leave some straggling files from previous rom which are most likely going to conflict.
but try some different roms and let them settle. give them a couple days. if its not going to work for you, try the next.
one rom just wouldn't run on my phone and that was Carbon Rom. I tried several different versions, with and without alternate kernels. always clean. many swear by it and love it, that's why I kept trying it, but it just did not like my phone. no biggie, plenty to choose from.
don't take this the wrong way, but if you the only one suffering from a side effect, than it is most likely user error. there are many glitches throughout all roms and they are usually well documented in that thread.
refer back to my last post in Padawan. again, my flashing process may be overkill, but you cant get much cleaner than that

Very common at about the 10 to 12 month mark. Battery starts to swell. You can get stronger battery for $8 on amazon.
