Started with root/ROM's last week. Loved Vicious and I love BB more. But both did not provide battery life I want. I went out on a limb (for me!) yesterday and bought Franco's app. Not knowing any better, I just flashed Franco's "nightly" kernel, currently #241. Battery savings are now significant! GREAT kernel for me. But, I want to understand things a little better. Here are my questions:
- In the app, it says that I have: "Installed Version 3.0.40 - franco kernel nightly", but then it says " Installed nightly version 241" Which is it??
- What is the "Leankernel"? Any advantages for me to use this instead of the "nightly" version I have now?
- Does "Latest Exp version" mean latest "experimental" version?
Thanks in advance for you help!
It doesn't say installed 241 it says install. And lean kernel is a different kernel by a different developer. And no not really any benefit. They are both just about the same. And yes exp means experimental. Which doesn't mean its not use able or truly an experiment just means he added something in to test. And until he deems it stable.

Thanks Uber for the quick reply!
Regarding the "install" confusion, here's the content right out of Franco's app...
Installed version
3.0.40 franco kernel nightly 384gpu
Installed nightly version
#241
...
Maybe it's Franco's version 3.0.40, which is somewhere indexed as #241 in some kind of running list? Just guessing!
I think the 3.0 40 is the binary version number.
Just curious, what settings did you put in for battery life? On the same kernel but I swear it's worse than stock re: batt life.

Oh okay yeah forgot. #241 is the build number and 3.0.40 is the Linux kernel version and 384 is the GPU. #241 is the number of builds he's had and that's the version.

Thanks again Uber - makes sense.
jtag - stock settings. I selected 384 for the gpu clock.
It was like getting back to ICS- "last all day"- battery life. When idle, this kernel seems to not use power at all on my Gnex. In fact, when I got down to 11% late last night, I turned the screen off for about 20-30 minutes to do other stuff, came back and it read 12%! On the stock BB kernel my battery drained pretty constantly even when idle.
I've learned here that results with various ROM's and kernels vary widely - you probably already know that. For me, BB ROM with Franco kernel seem to work very well together.
You probably weren't getting deep sleep. But just about every other kernel is the same. its all up to how you configure it. I have mine setup so well I can play dead trigger and it won't even get hot and its running at 1.2ghz and GPU is @ 512. And it will barely feel warm and only drop a few percentage.

I'm getting crazy good battery life and performance on lean kernel and AOKP. Franco is good too, but I think I'm getting much better battery life on lean.

James Bond kernel.
I've seen what franco has done with the nexus s kernel, realiable, smooth, and constant updates, it was always my choice. So as soon as i get my GN its the first kernel i'm going to flash and hopefully it won't ever disappoint
same for me. I have a freaking good battery life on lean but better performance with Franco

its Imoseyon kernel on Rootzwiki. btw, Ive tried both Lean and Franco kernel, I still prefer Ezekeel Glados kernel though. amazing smooth and friendly battery life.
I was using franco's kernel, but with all the hourly updates lately, it spooked me a little, so now Im on trinity inferno512 kernel, and wow games run fluid with the GPU at 512mhz.
im still debating... im jumping back and forth but i need to stick to one for a week and try it out!
leankernel has updates just as much as franco... i say thats a good thing
i say take a week long test and run some benchmarks with each of those kernels, take a screenshot, and come back with what you like.
Im working on that now.
GLaDOS is by far the best kernel for my phone. No lags whatsoever and four hours of screen on time with the stock battery
I'm starting to lean toward glados myself. I've had a lot of issues with Franco's 14.x kernels.
I've also found lean kernel to be a bit choppy. Shadow gun runs really choppy w lean kernel, but ultra smooth w either Franco and glados. It could be that I'm not using the correct governor though.
I have tried both back and forth. AS of last update I've tried franco 14.4 (deep sleep ~50%) which is good but has a much better battery life (deep sleep at 91%) on hotplug of lean 1.8.0.
+1 for lean
I have used lean kernel for a while now. I used to get lots of lock screen lag with Franco. Which I don't with lean.

Im on Leankernel 1.7.3 right now. Used Francos way before, but after Version 13.1 i started to get battery drain issues. So i switched over to Glados which seemed to have a good battery life to me, but was very choppy overall on Wheatley Gov'.
Lean is the best for me at the moment, almost 4 Hours Screen on time isnt a problem for me, i use the build in InteractiveX Governour, with some heavy undervolting. Data, Sync, Wifi , ... everything enabled. Screen Brightness ~ 35%
I gonna try Lean 1.8.0 Later that day. But i have to admit that Franco's next upcoming with Turtle Governor might be an interessting choice either.
For me, both devs are doing a really great job, both Kernels are good.
I've used three different Franco kernels and had freezing and reboot issues with all three of them. Never had an issue with Lean Kernel.
I don't care what kernel I have. If:
1.At the end of the day on my normal usage phone has less than 60% of battery left it means that the next day I won't manage
2. I have less than 60% I have to recharge overnight
3. Phone can get me throughout the day on heavy usage ...
Don't need any fancy kernels if they don't tick the first box
Edit:
Just tried lean kernel and its way to slow. Scrolling in text app or anywhere really isn't even half as smooth as Franco ....

After trying many kernels... I always come back to Faux123's kernel (Currently 011b10u). It's just such great battery life... idle battery drain is just a horizontal line on the battery graph for hours. LOVE IT. (P.S. Ultra-liquid-smoothness too). http://rootzwiki.com/topic/12512-kernelgn-lte3017ics4023uvgpucpu-occifsslqbotgfiopsv010jan-17/page__st__930

So I've been using aokp for months now and franco's kernel even longer. both amazing pieces of work. franco's kernel has been 99 percent stable for me, with an occasional sod with a few builds here and there (nothing a full wipe can't fix). However after my last sod, I kept getting forced reboots upon startup so I just flashed the newest version of aokp and it's been working fine as expected.
my question is, can you guys tell me exactly all the advantages of using franco's kernel with this rom as opposed to the stock? even after using it all this time (since early December) I guess I haven't noticed any significant differences. maybe I haven't paid enough attention because so far this stock kernel in aokp seems to be handling everything just fine. thanks in advance
Sent from my Galaxy Nexus using xda premium
Ok..., let's give it a try:
Franco's latest (nightly) kernel has (in contrary to stock AOKP kernel):
Sound Control (in latest builds from Ezeechiel (is that the correct way you write his name?))
GPU overclock
HotPlug for disabeling 1 CPU whith screen lock
USB Fast Charge enabeled
Wifi Power Management for better WiFi reception on screen lock
Color control.
I'm sure I forgot some settings.
Right now I get about 1% of battery usage in 2 hours when idle with data on (not Wifi), maybe 10 - 20 % with screen on (depending reception, what I do etc.) and I never have reached such figures with stock. I would for sure recommend Franco's kernel but a lot depends on your preferences. For me long lasting battery is important so I go easy on the clock speeds of the CPU.
thanks. that's the kind of information I was looking for. I don't feel the need to overclock but if there really is a good improvement in battery life, that's reason enough

What's your favorite kernel, considering battery life, speed, OC/UV options, and stability? I've been alternating between leankernel and franco.kernel and can't decide which I prefer. If you choose other, specify what your favorite is!
Trinity and lean are my favourites
Trinity... lean was also good for me...

I am using the kernel that come with CM9 beard off of Linux and I love it, I am getting better battery life using this than Franco's, but I'm not sure if you can just the kernel, I think you need to be on the ROM as well...

i've tried lean,franco,glados and trinity..
both lean and trinity are my favorite, but for now i think i'll stick with lean
trinity for smoothness and super fast kernel
lean is for fast kernel + good batt
the latest trinity kernels...ofv and flatline are equal and in some cases better batt life then lean...without sacrificing performance...
I just recently purchased a Galaxy Nexus and have only tried out Franco Kernel. I get an average of 3.5 hours screen time while underclocked. After I record some accurate results, I think I'll switch to Lean Kernel in order to see which Kernel gives me the best battery life.

My thoughts exactly, although I've had my GNex for over 2 months.
Why not try both yourself for a while? Just flash them and see what suits you best... For me I started with Franco and just sticked to it as it works perfectly for my needs but I can't compare the both.
Tried Franco kernel, 17.2 give me the best battery life with slightly more than 3.5 hrs on screen time, for M1 and M2, can only last slightly less than 3 hrs on screen. Anyone also experience this?
Anyone here tried GlaDos kernel and have any reviews?
GLaDOS review
GLaDOS has both speed and good battery life. It's more or less based off the theory that processing stuff at higher speed will allow your phone to get more quickly back to sleep (not the same as "Deep Sleep"; the C4 rest state happens concurrently, even when you're on 1200 mhz).
But the only way to see if this pans out is to use it. You should try it with your daily usage and see if it works for you.*
For example, I find it has the best battery life for playing music with screen off (3% per hour speakerphone, 5-6% on bluetooth) and matches [or beats] the others for stress-usage (screen on, 8-10 apps in background gets around 20%). I haven't tried intermediate usage, because frankly, I don't use only a few apps when I'm using, so that's a gap to fill I guess. Note: streaming music is apparently a problem, judging from recent reports.
*Use BetterBatteryStats or an app with series history; the graph should become linear partway and that's when you know to take numbers.
Yeah but how do you backup your default kernel?
I just installed Franco kernel, why would one install lean kernel? what's the difference between two anyway?
I think the answer to this question is, 'it depends'.
I think the ROM/Kernel combination has an impact on performance and battery life.
For example: previously while running bixie's stock and AndroidME, I had great performance with Trinity. However, on AOKP, trinity delivered poor battery life. With AOKP, I found Franco to be a better match.

OK, you're right I didn't really gave you enough information on my end)
I'm using stock Jelly Bean 4.1.1 OTA, I did rooted my phone so that I can install different kernel
I'm using few social (facebook,google+,foursquare,etc) apps, some messengers (what'sup,kik,google voice)
as far as data goes I'm using Juice Defender and that helps me a bit with my data on/off
but what _REALLY_ kills my battery is screen, in the best case scenario I was able to archive a little over 2h of screen time and in most cases it's ~1:30h
i'm using standard battery in my phone.
my goal is _SOMEHOW_ increase screen time
that's why I'm trying out franco kernel)
Stock.

I've never had a problem with the KT747 kernel, but somehow the latest build (9/18/12) is giving me huge battery drain and I'm thinking of switching to the latest faux (v013) kernel because I don't wanna go back to stock. Keeping battery life in mind, what would you recommend between the two and what version of that kernel? (or three if you're recommending stock kernel) Thanks.
On a side note: I'm sure that there is no rogue app or some other mysterious problem sucking out the power because I made sure to check w/ BetterBatteryStats, and the app is pretty much accurate for me.
Did you wipe cache/dalvik cache? The 9/18 update gave me a significant improvement with my battery life.
Newer release of KT747 out as well. I can't speak about Faux's kernel as I haven't tried it.
Im with the Op on this one...the 9/18 kernel is not 100percent right ..but the one before that i think 9- 12 or 13 is the one im using now and it works great!
I love the K tweaker i uv by 50 on all mhz and have no problem oc'ing to 2.1 all day i use 192 min 2106 max ondemand with juice def ultimate and with moderate use get 18 or so hrs and great quadrant scores altho they dont mean **** lol but here they r hope this helped

is there a good kernel that is cm10 supported that increases battery life? last night i was testing out while running AndroidME Cm10 1.8.0 and on idle it took 8% of battery in like 8 hours thats horrible compared to the 3% on mincho and like 1% on my iphone 4 xD
so whats a realyl good kernel you guys have had used that gave you very nice battery life?
generally if it worked for most of the population it will work for me so dont give me your device is different bs thanks for any helpful suggestions

dude that its not that every device is different chances are my device is like most of the population sure i dont doubt that all devices are not the saem but generally speaking mine could be the same as yours
I use CM10 with Leankernel, as I just wanted a simple Kernel. However I did under clock my phone to 920mhz. I found that this keeps it much cooler and I'm not seeing a difference in performance running it lower.
With all that I can get a little over 2 days standby time, as long as I don't have location services running.

100 percent doubtful. There are extreme variances in the SoC even from within the same production run. Couple that with other hardware differences, and it becomes obvious how utterly inane these battery life threads actually are. There is but one singular answer to the question, and no third party can give it to you.

I saw no difference between the consumption of CM10 and stock Rom.
Tests
The latest test in our galaxy nexus , we provide to show how different kernel will enjoy their users and create a ****ing fan club, ROM is theoretically irrilevant, every ROM had ( theoretically ) same battery drain, some rom is better, some is wrost, not too much anyway
there's some kernel don't require attention from you, the 2 is Google Stock ( for stock rom ) , CM10 Stock ( cm10 based ), the motivation is really simple, this kernel will be a stability milestone and classic kernel from phone, their dont include any improvements or another things, and anyway it's not really stable or secure as promise, because it's not updated ( google stock ) or include some ****ty commits ( cm10 kernel ).
Our attention is to custom kernel, people will always point trinity as best, it's is but not completly , this kernel has particular clock ( under stock OPP ) , that permits more stable UnderVolt ( using same values in franco , it's crash, in trinity is rock stable ) and save your balls from MPU.
i use Interactive 300-1036 ( 775mV -> 300mhz, 875mV -> 639mhz, 975mV -> 1036mhz )
Another attention is releated to Lean and Glados projects ( in XDA it's author dont open any thread )
Leankernel promise always patched kernel ( from mainline linux ) and lean, smooth, fast, Leankernel interactive is best governor tuning here, very low consumption but there's problem , because it's not have control app, it's hard to tuning right!
Glados is lead kernel innovation,but it's not updated and dont support CM10
Faux kernel is good, but too stock-frequence and governor, dont like it
Iphone4 use less battery ( not really ) becouse it's missing alot android features, disable mobile data, auto sync and wifi and set your brightness to 10%, your phone will be infinite powered.
i do heavy uses ( 4-5 hours screen on ) , i come back to home at night with 10-20% , perfect
