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

Alright, so I'm coming from cm 6 and I was using snap with it. But what I'm wondering, is what is the best kernel for fresh.
Thanks.

I'm running King's latest...#8 I think. Getting 53fps, 1250 Quadrant score with stock 998mhz speed. Seems good so far.
If you want great battery and dont care about the fps cap, stick with the latest stock kernel thats built right into fresh.
best kernel for lastest fresh?
I am using the kernal that came with the rom and it seems to work just fine. i thought the claims on battery life might be over rated but can say that with moderate use i got 37 hours from 100% to 15%. Might try kings again but not sure if that would hurt that battery life.

I promise you that the claims of improved battery life for the new HTC kernel are not overstated at all. In fact... there are no words to describe how much of an improvement it actually is. The theory follows that the other kernels will be re-optimized based on the new HTC kernel.
As above, stock gets the best battery life. If you need the OC/FPS/etc you can try King's #8 (I had stability issues, personally) or #6 (worked like a charm). Currently I'm using the netarchy 4.1.9.1 beta. Battery life could be better IMO, but feels really snappy. LP looks too good @ >50 FPS for me to stick with stock.

I have been running Fresh 3.2 with the built in kernel, but I've also been using SetCPU with a very low performance, battery friendly profile.
My question is whether I should be using SetCPU at all anymore, since I heard that this new kernel already supports throttling the CPU back when not in demand. I've been excited to test out how it effects my battery myself, but if someone has the answer, it would save me a week.

Even if the stock kernel does scale down the voltage to the CPU, I think you would still need setCPU if you want to OC. However, the stock kernel probably does not support OCing. However, I think setCPU could still be beneficial for keeping the CPU running at minimum when the phone is in sleep mode. Then again, that feature could also be incorporated into the new HTC kernel for all we know.
Like someone else mentioned, Kings BFS #8 gave me stability issues, but #6 works fantastic in terms of performance and stability; not to mention, everything works on my phone as it should. I got 2 generic batteries and a charger from eBay for dirt cheap, so battery life if of little concern to me.
Is there a kernel for fresh 3.2 with cifs support?
Which one do u perfer guys ? Both are awesone and cant make a decision Battery life ? Hotplug efficiency? Performance ?

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.
Each phone is different find out your preference on your own

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

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.
Sent from my Galaxy Nexus using xda app-developers app
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.

Day 4 on Franco kernel with BB. Battey performance is so good, I turned Google Now back on!
Hey guys, when i started using the epic touch which was pretty recent, I jumped straight in to the 4.x toms. Currently on blu kuban. Now I really want to go to the best possible gingerbread rom for battery life. I have no idea which rom would have the best battery but I am extremely frustrated with my battery drain on ICS. Can anyone please give me their opinions from what they remember from the gingerbread days or if there is any other way i can drastically improve battery life on ics either with a different rom or kernel? Thanks.
On GB the popular roms I remember were Caulk's and Blazer but I had a stock rooted EL29 setup that I stripped down myself and used QQ Launcher on and really enjoyed for a while. Honestly though battery life is really about the same for me on ICS and GB. I'm currently running agats rom but wicked sensations, aokp, and black rom are all pretty similar in battery life. I'm also now undervolted by -.50 and that has helped even more.
Honestly though its really just a matter of managing your phone and knowing what is running and burning up battery in the background. Use dark themed apps, turn off wifi and 4g when not in use etc.. I also use data enabler widget and turn off data at night now then just toggle back on when i wake up. Last night I dropped 2% in 6 hours.

thanks man, so a noob question now. I never undervolted. I just switched to Universe v2.0 rom which now uses kuban kernel as well. what does undervolting do and how can I help?

Undervolting is supplying less mV to your CPUs. In terms you can extend you battery life as the phone can operate at the same speed using less voltage. (Less power used, more battery available)
With that said, don't under volt too much usually -25mV to -50mV is optimal if you go any less you run into the issue of nit having enough voltage and your phone could freeze or crash. Both agat's and kuban kernels offer undervolting and under clocking.
Just a FYI I'm using sleshepic's the governors kernel. No undervolting, just have it set to CFQ and Pegasusq at 1000 Max and 200 min and I've been getting around 11 - 12 hrs with moderate use.

Yes voltage control on kuban kernel allows you to under volt. If you click on each step(slide the voltage to the left) you can under volt it. Then apply settings and your good to go. PM me or reply here is you have any more questions.

Voltage and governor control is now built into Kuban ROM. It's all in extweaks in the system menu. You may want to try it out. You will be losing a lot going back to gingerbread. I actually get better battery life on Kuban than I ever did on GB. And I haven't even messed with under volting. I do recommend the Wheatley and Skywalker governors for the perfect balance of performance and efficiency.
Kuban has been good for me as well.. I don't under volt at all.. To unstable on my phone.. I get 4 hours screen on(heavy use) and good deep sleep with the Kuban kernel(1100-200), placebo tweaks, odexed a few apps, and a modified framework to make it more zippy without compromising battery
