haven't seen this discussed too much, and I'm curoius what others are seeing with battery life when it comes to Stock vs Custom kernels...
Hands down stock kernel, has seemed to be better than any custom kernel i've tried for battery life. and maybe i'm doing something wrong, I've tried all sorts of rom / kernel combos and can't seem to beat stock kernel...
Are you guys seeing something different?
I'd love your opinions!
Thanks guys!

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.

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?

Hello everyone.
I'm a cognition rom user (currently 1.5.1) for quite some time. Everything is fine, no bugs, no problems at all.
I'd like to ask you guys if anyone has tried another kernel other than ninphetamine that the rom comes with, and had better speed/response/battery life.
Any suggestions?
If you manage to get to my reply beneath that monstrosity of a signature, there's currently 9,365 posts of discussion in its thread [ROM][2.3.5][XXKI3] Cognition S2 v1.6 | Now Live!.
If you're looking for opinions about something related to the use of that ROM, I'd suggest reading through that thread. Searching that thread for "kernel" returned 945 posts.
Siyah, Speedmod or stock based CF Root are the most popular as the moment.

Ninphetamine development kinda stopped at 2.1.3 a while back.
Speedmod, at least the last time I tried, lacked quite some features. It doesn't even do custom boot animation.
Siyahkernel, very good. Pretty much all governor/schedules are there with NTFS support, bln, and very active in development.
CF-root kernel, as stock as it gets. For 2.3.5 anyway, it's been reported to have great battery life. But it doesn't have many functions beyond that.
In any case, the battery life on each kernel, if you don't oc/uc/ov/uv, you won't see much difference. The android os bug, which drains your battery, still happens in all kernels occasionally, when it doesn't happen, battery life depends on your other apps running in the background.

Hi All,
I have been using CM7 and Dorian´s Redpill Hybrid. But now I need something much more stable and with great battery life. My problem is that at times I get random reboots and the screen is unable to be unlocked.
Now I have had a lot of ICS theming and I would like to keep some ICS-like stuff. I know that for battery its best to use Faux optimized kernel.
Now I do not really mind if I have to go back to nearly stock with blur and all, but I really need a rom that will not freeze up on me and will not go randomly rebooting on me.
Thanks to all for any help!
I'm thoroughly convinced that the "freezes" and "random reboots" is an inherent problem of the Atrix itself as it happens across all ROMs (either in my experience or through reading about it in threads).
Go to each ROM thread and view the most recent pages to see what people are experiencing in regards to battery life and stability. The responses you get in a post like this will more than likely be far too biased and inconsistent with actual usage.

Neutrino and CM7 stable with Faux 0.2.3 1.0ghz seems to be the best combination for me, have nothing but good things to say about both.
As for reboots, I can't say I've had the problem, but it seems like lots of people do from time to time, more so on other roms that I've noticed just glancing over threads.
Neutrino has to be one of the best ROM's I've ever experienced. It's well maintained and has a host of performance improvements. I've experienced some of the best battery life AND stability with this rom.
The ICS alpha is going well but its a long way away from matching the maturity of Neutrino. The battery life is still an issue though so I wouldn't switch just yet. Once the "bluesleep" problem is taken care of then it will be a great rom with ICS as its backbone rather than just a theme!
I'm trying to decide which ROM to have on my phone (and kernal)..
Obviously I'm looking for BATTERY LIFE, PERFORMANCE (with NO lags), and actually loads apps without crashing!!! ..Which some do!!
WHAT IS YOUR CHOICE OF CUSTOM ROM AND WHY?????

There is no "best" rom. What suits me may not suit you. However to answer your question stock is best for me with a custom kernel.
Okay its "KERNEL" and if I were to pick my favorable Rom, it would probably have to be SyndicateFrozen for the Epic 4g. I even though it's outdated, it was and probably still is one of the most well known roms

Which kernal do you use with the stock rom?
Does it help with battery life and prevent lags?

Depends on what you need. Siyah and franco provide tons of tweak with most important being sound boost. Speedmod is good too with increased brightness for low and mid light conditions. Speedmod also has mdnie tweaks which makes text sharper
This thread will probably get locked by a mod, "best" ROMs/kernels are regarded as OT and taboo, and rightly so, because it's way too subjective.
There are no short cuts - you just have to flash, try and repeat as necessary....
Closed, "best" rom threads are prohibited on XDA, as there is no such thing as a "best" rom.

Different roms and kernels yield different results for different people. Someone may get amazing battery life on one ROM, but you may not. That's why it's recommended to try a bunch out and see how your phone behaves after a couple of days of use. Viper4g + Enoch kernel is the winning combo for me in terms of battery life. Someone else may have different results though.

You gotta give us more info man.
Basic power saving tips still apply, I would suggest starting with them
based on the info supplied flash back to complete stock and test that.
if you have good battery life it was the rom you flashed. If not its a device issue.
