I've been trying different ROMs and kernels on my Fascinate. I haven't run into any problems that I counldn't fix, though losing my Verizon voicemail took me some time to figure out, but I did. I've tried different ROM/kernel combinations trying to get the best performance with the longest battery life. So far I would have to say the best battery life came with Super Clean v.9 with the StupidFast v1.54 kernel. It also performed well. But I like the looks of the Super Dark ROM but I can't couple it with a kernel that gives me really good battery life. I've tried several of JT's non-voodoo kernels and StupidFast SV and UV overclocked kernels, the overclcoked SF is giving me alot of FC issues. Unless someone can give me recommendations I guess I'll go back with Super Clean and Stupid Fast SV.
Personally, I found DJ05 and SirGatez BlazedEclair kernels to have incredible - of course, after the the battery is calibrated that is. Almost no loss of battery during the night or during standy, and the amount of battery used in applications has been the least with the BlazedEclair kernels. BTW, I do use the Voodoo5 versions of the kernels, haven't tried nonvoodoo.

I see that there are a multitude of threads on this forum about best ROM/Kernel combos, but I am looking at it from the standpoint of which gives the best battery life. Performance is not an issue, all I am trying to do is get excellent battery life. I would like to keep SenseUI if possible, and an undervolted Kernel is a must. I have seen some information on Ava-Froyo V9 and was wondering if anyone has tried it and do they like it? Any information would be much appreciated.
I loved Baked Snack 1.7, and at one pointing got 21 hours of battery life, I am using myn's Rom now andking it so far, both use sense

Go to the kernel testing thread. In there you'll find which is most efficient, the idle energy draw is probably the most important stat. FWIW, CM w/ Snap 9.5 has the lowest energy draw and so probably the best battery life -- it's what I use.

+1
if you like sense,
ROM - evio 1.4 or baked snack 1.8
kernel - kings #6 bfs or baked snack #6 (reads #2 in software info)
+ 2 to looking at the kernel comparison site someone put up.
To me it is completely biased though because what works great for one person and their EVO does NOT mean it will work as great for YOU. I would first find a ROM that you like and then experiment with trying each different kernel. Remember to wipe the caches before you switch kernels and give them a few days to balance out and see what they are like.
Personally I get the best battery life with CM 6.0 Final + Kings CFS.
Then there is the whole CFS vs BFS debate, again TRY IT FOR YOURSELF. My phone eats battery like crazy and it will drain in a few hours, with moderate use, and if I switch to CFS I get about 40% more battery life.
So what I'm trying to tell you is that take everyone's recommendations with a grain of salt and try every kernel and BFS/CFS and see what works best for you!
Good luck man
I'm getting ~36 hours off Fresh 3.2. I tried going to 3.3 and tried Myn's but neither came close. Not sure what the difference is, but I'm good with it.
Thanks for the replies guys, it's been a big help!
Well I finally did it last night. I had tried many ROM/kernel combinations to get the best performance with the longest battery life. I love the looks of the Super Dark DJ05 ROM but I couldn't get a kernel to go with it to give me great battery life. I'd take it off charge about 6:30 am and it would get down to 30% usually by 12:00. I have been rooted for about a month and have been reading about voodoo alot. I finally downloaded a StupidFast voodoo kernel. It went perfectly and the battery life seems to be better. My question is should I run SetCPU and if so what settings should I try? Any other kernels I should try also? Can I just flash a new voodoo kernel over the current one? I've read that you can and I've read you've got to disable the lagfix before reflashing a kernel.
I have found a combination for my phone, may not work on all phones. I am rooted, running voodoo, running jt's 1134 voodoo kernel on the Super Dark ROM. I was looking for performance with long bettery life. I flashed the kernel about 5 hours ago and I had 62% battery. Now I'm only down to 48% after internet, recording video at a birthday party, and a few calls. That's much better than any other setup, voodoo or not. I'm also running SetCPU set at 1000/200 with screen off profile set at 400/200 to hopefully save bettery life when it's asleep. FWIW it's scoring 1688 quadrant. What does everyone think? Thanks for the insight.
TBH with you I have been wanting to try out voodoo myself but I am still not entirely sure what it is. I know it is a different type of kernel, but thats about it.
I'm running Com Rom 1.3, and was looking for some kernel recommendations. I'm running the kernel that came with Com Rom which I guess is OTB, I never flashed OTB 1.4 so I don't know if I am running it. I was thinking about PeanutButta Jelly Time but was wanting some reviews on it first.
I am running PB&J 50 but found the smoothest is 100 and i will most likely flashing back to that later today.
But i could never get ComRom to run with OTB 1.4 so i cant really compare.
Good Luck!
what are you looking for? with otb you can customize your clock speeds/voltage settings to maximize speed or battery life. with pbj your locked into set values.
I know it doesn't get talked about much, but I've always gotten my best results with times_infinity's ComaVolt kernel.
Im looking for the best stability, speed, and battery life

OTB 1.5 running great for me.
Personally, the kernel in ComRom works great for me,so that is what I use. As far as other kernels, I have used some versions of otb which was good... but you have to find the right configuration for yourself.

Amen. You could get 1,000 replies on this and you will eventually get recommendations for every available kernel. Everyone's set up is a little different, and there are even differences in each phone as they leave Samsung. The only way you will know for sure what works best on your phone is trial and error on your phone. A lot of people are having great success with OTB 1.5. For some reason on my phone with my set up on Comm ROM 1.3 and any of the OTB kernels, I get sleep of death. I'm using ComaVolt and having no problems. That's just unlucky for me that I can't get the OTB kernels to work.

Same for me. Every OTB I tried give me SOD after about a day a half and I tried all sorts of different voltage combos. Comavolt game me SOD after about a day. I'm trying PB&J now to see how that works. I'm starting to think my phone does not like any UV kernels at all. Hopefully I can find a setup that works.

I have found the OTB kernels the most stable because you can choose to uv them or oc them, but you don't have to.
My own personal experience is that my phone can be uv'd to a point and then it gets flaky. I can nowhere near uv the way some others can... But I can experiment.
My current setup that seems to work best is OTB 1.3 with uv'd at least -50 everywhere and oc'd using 1200 as the limit at stock 1000 voltages. Gets me quick and responsive phone and seems to give great battery life (because most of the time the phone is spent at the lower steps where it's moderately uv'd).
I've tried imnut kernels and keep coming back to the OTB 1.3 (because 1.4 and 1.5 seem to break other things for me). For me, EVERYTHING seems to work on OTB 1.3.... BT, WIFI, everything...
But like others have said, YMMV. Good luck!
Well the -50 mv PB&J kernel is a no go as well it looks like. I got the SOD already. I would really like to UV, but my phone doesn't like it.
Wow. Just switched to peanutbutta jelly whatever -100v. Battery its invincible, and performance shows no lag. Literally my battery has only gone down about 3% in the past few hours with wifi on and light usage.
Try the comavolt kernel. I just flashed it yesterday after replying to this thread and have been running it nonstop since then without issue.
Battery life on comavolt is ASTOUNDING. I mean like shockingly good- on my phone at least.
I tried comavolt and got SOD on that too within a couple of hours.
I went with PnutButta Jelly Time 100, I like it, great battery and stable.
the otb kernels seem to work the best for me.
Ok - I normally don't use a kernel, but my battery life blows on ICS.
Anyone have a suggesstion for the NS4G?
I'd like to avoid overclocking, but I guess if the kernel has it, I can revert to stock with setcpu.
Thanks!
Depends on what you define as good battery life. I manage 17 hours, which is fine by my standards with my usage pattern. Some people can pull a day with normal use and I mean 24 hours on stock battery. I've stuck with Matr1x because it has what I want in a kernel. Stability, decent battery life, a variety of governors to toy with, and Voodoo sound . I'd say give it a go. There are so many out there and I've messed with a few. The life hasn't really changed between them though. It just seems Matr1x hasn't given me any issues.
For stock, thalamus provides an optimised stock kernel.

Pick your poison. It doesn't have all the voodoo, bld, etc, but I get 18 hrs with about 3 hrs of screen time on it.
Trinity kernels are also excellent and their colours are spectacular. They have all the bells and whistles.
Ultimately it's up to you though. Try a few (after you've made a backup of course) and you can always go back should you encounter any issues.

I also would say Matr1x, I was able to get 5 hours screen on time with 15 hours of total use yesterday, not sure if you will get the same result on stock but it should help
Hello,
I am going to stick with the Stock + Rooted combination for now with Xposed modules. Would like suggestions for which kernel provides best stability, battery life, and performance. I know EX, Franco, and AK are always safe choices on custom roms but I've never tried custom kernels on stocks roms. Suggestions or personal experience reviews are greatly appreciated.
I just asked this question not too long ago and landed on using Franco's kernel. I will mention I'm not rooted, so I am just using the settings that come with Franco's kernel. However, I have seen improvements in battery life and Bluetooth connectivity that I was hoping to see.
I've been running Franco for a while. It's really a toss up between Franco and ElementalX. Both have amazing stability and battery life, both can be tweaked eve further from the "stock" behavior through things such as battery profiles. I haven't done any of that, you have to pay for and use their app to do so. I've just left it at "stock" behavior.
Thanks for the recommendations. I'll try Franco for a while. Also will give Kylo a try at some point.
Just switched to Franco kernel a few days ago and my battery life has drastically increased.
