Ok, Sense-lovers, what's the best kernel? - EVO 4G Q&A, Help & Troubleshooting

I'm back to the dark side for the time being, but I'd like a new kernel that unlocks the FPS without breaking my camera. Also, some overclocking would be nice.

I am actually in need of a kernel that I can flash that has the perf-lock disabled for underclocking but I don't care about the FPS at all. I just want my 8mp camera back.
Any ideas?

Evio 1.1 is great. As for the second post, use it with other kernels and setcpu for great ocing capability

I've been using it on my stock rooted evo 2.2 and its much snappier now. Unlocked FPS, Overclocking, and a hotspot with Wireless Tether Pre8

netarchy 4.1.8 cfs edition is great

The new htc kernal has been giving me phenomenal battery life, but has 30 fps cap and is not overclockable. I have been pretty happy with kingklick, but with this battery life, I am sticking with the htc. Just a matter of time until this one gets tweaked.

Make of that what you will. I still don't know what the advantage of older Kingx's kernels would be, but I never really looked into it. I'm using #8 BFS now, seems great so far.

Wow, that was an awesome paper! I had absolutely no idea what BFS or CFS were until I read that. If I understand correctly (in a vastly-oversimplified way), CFS assigns each pending task an equal share of the CPU, while BFS decides which tasks will be completed faster and queues them accordingly. CFS improves turnaround time, but BFS lowers latency. With such an interactive system as a smartphone, BFS would seem to be the best choice.
Or maybe I'm completely missing it.

For user experience (as measured by interactivity), BFS would appear to be best choice.
However, I would like to see a study that measured power used vs unit of work done. Since CFS's turnaround time appears to be lower, this suggests it may be a more power-efficient kernel?

Netarchy vs Kingx vs New Fresh Stock Kernels
I don't have SetCPU, so my test were done just flashing the kernel and running the benchmarks. Haven't tested the battery yet, but I'm going to keep netarchy on for awhile and see how it does. I'm using the new Fresh 3.2 ROM btw.

Question about setcpu and overclocking

I'm using kings kernel #5 and i currently have its over clocked to 720 (and of course profiles clocked under that) I was wondering would i have significantly shorter battery life if i clocked it up to the highest (1.119) and set it to conservative

You'll most likely freeze up and crash at the highest clock speed, that's what happens to most of us. But that really depends on your hardware... You MAY be able to sustain that, but there's really no guarantees.
What I do (and I have pretty good battery life, it's 9:36 pm here and I just now dipped under 20%) is let the kernel do it's own thing and only set up a screen off profile that maxes out at 460.
But yeah, higher clock = more battery drain.
I cannot get over 1.113, reboots constantly over that. I get amazing battery life and performance with what I am running below.
Sent from HTC Incredible, Redemption 2.0.4, King's BFS #5 kernel OC to 1.113, s-off, Launcher Pro Plus
Oh I can run it sustained i have my charging profile of 1.119 and interactive. Its 11:15 and my battery just dropped under 50% (i like bragging) But i figure it i put it to conservative it probably wont ever need to really run at max will it? Im not 100% sure on how everything works just yet
The word of the King
When King released #5, he was specific in saying that if using SetCPU w/ #5, only use it to overclock, as the composition of the kernel handles battery life.
That doesn't mean you can't, obviously, but I'm just conveying what I read when it was released.

Oh well thank you i had no idea. I actually messaged him on here about the kernels

King's notes and his d/l site go into uber-geek detail on the differences - take a look. Short version (to my understanding and probably way oversimplified) is they do different things - battery preservation or speed or a blend of the two.
That said, the kernel you should use depends on the ROM and what's important to you [speed/battery/both] - certain kernels won't/don't/shouldn't work w/ certain ROMs.Take a read thru the development section, and read thru the 2 threads for King's kernels. He's got 5? (or more) kernels out in the wild. Between those two threads, you'll see where one set is for AOSP ROMs only, the other for Sense and/or vanilla, whatever.
I've made the error of bootlooping myself by putting the inappropriate kernel into a Sense ROM - fortunately I did no permanent harm - actually it was good learning. Why? Now I look for, and use, kernels specific to the type of ROM I'm using.
They aren't one-size fits all - don't make the mistake I did - read up on what's there and you'll see what I mean.
Kind regards.
Yea I learned that not all roms work... I have virtuous 3.0.1 and want performance but mainly battery life can you suggest a kernel for me?

Lee - best suggestion I can offer is for you to read up on the kernels available and choose the one that works with the ROM you are running, that gives you what you want.
The reading/learning will do as much for you as a super-speedy or battery-sipping kernel.
Good luck.
I've been reading but just can't find any real information
Sent from my Incredible using XDA App
The Kernels King post are defined by whether they can be used in Sense or Vanilla. His AOSP/CM are for Vanilla Roms only, and will more than likely cause bootloops if applied to a Sense Rom. The HAVS kernels are for Sense only. I change out between 2 and 5 and can't decide which is better. I also never run above 1.15 or I get constant reboots. 1.15 still reboots, but not as often.

[Q] Flashing kernels

So I've just started trying kernels. I decide to start with the popular Kingklix kernels. So I backup up my Cyanogen 6.0.2 and flashed his BFS #2
The kernel was very very snappy, but the benchmarks were really low (in the 600's) they seemed to lag at the "testing I/O" portion. But I didn't care because the phone felt as fast as the Captivate.
I charged it full, and went out for the night. The phone was dormant in my pocket for most of the time, maybe 10 texts sent... the phone died in 3 hours. This made me done with the kernel, as much as I liked it I need my battery.
So, I reverted back to stock and installed his CFS #1 kernel, I cleared Dalvik (I did this before and after the kernel flash like I did with the BFS version) and booted.I cleared the battery stats since the phone was off now and I might as well bump charge. This previous charge stayed forever! I got 1d 4h and 40m on this setup before getting 14% and the phone saying to plugin
The CFS isn't as snappy as the BFS version and I'd love the speed of the BFS one but I need more then three hours of battery... so I have a few questions.
1. Can you flash kernels ontop of eachother? or do you have to restore to stock in between flashes (much like themes on AOSP roms)
2. Are the low benchmark scores normal for Kk's BFS #2 kernel?
3. Is clearing battery stats part of the procedure? and is that what made the difference between the two kernels? or is BFS just poor on battery life?
Clearing battery stats really isnt needed, kernels can be flashed on top of each other, and king BFS 2 was really buggy, use 1 Cfs, it may not be as high in quadrant, but quadtant doesnt mean anything. Cfs is more stable, and the code for the cfs is 2.6.32.21 whereas bfs is all buggy and is 2.6.32.51.
Sent from my ADR6300 using XDA App
I knew quadrant didn't mean anything when I saw BFS and it's low scores but amazing performance. I hope he patches it up, the alternate scheduler really makes a noticable difference.

[Q] Best Kernel For Me!

I have the HTC EVO Hardware version 0003 (old camera chip)
I do a ton of WIFI Tether in places with not the best signal, so signal is huge!
I want something with relatively good battery, but will compromise
I typically have my phone in my pocket most of the day, and i do have a spare batt
I use my phone as a computer so i would like it to not be super laggy
I am on Koni's Elite Series 3 Rom currently but I like all modified sense roms.
Just trying to see what people think and get ideas. Oh and im currently using HTC kernel #15. Im not sure if 15 is CFS or BFS. Anyone know?
Well its hard to say; kernels react differently on each phone. I've had the best performance/battery with netarchys kernel 4.3.4 CFS LESS HAVS SBC build. It also has HDMI built in. You have to test drive kernels to see what your phone likes. I usually run a kernel about a week before I test another one.

good idea. should i be wiping my battery stats every time i flash a new kernel or rom?
any suggestions for a few kernels to try. there are so many out there and im not exactly sure what to look for. i mean i have a basic understanding of what cfs and bfs, havs, and smartass governers are but i just dont know where to look. thanks for any help

I love koni's rom and I've had the best of luck with the cfs havs less kernel. It also has hdmi support. You should get setcpu and set the Max frequency to 1075, and min frequency on 245(with conservative or smartass governor). My battery was great and performance was insane. You can overclock to 1190 if you want but I just sit around 1075 or 1113. Here's my personal fav for all sense roms. P.S I usually wipe my battery stats once I hit 100% before or after kernel flash doesn't matter(for each kernel).

New to Evo 4g From Epic 4g- Battery Life Stinks - WHy is Epic 4g so differenT?

I've been reading around the forums in different threads and Man there is a lot to catch up on since I've always been an Epic 4g owner and not an Evo 4g owner. I've found a few threads about battery life and so far have installed 4 roms to test briefly battery life and none are giving me the same as my epic or close to it which was 0-2% drop an hour when Idle.(Sitting on my desk on 3g or wifi) Gone through cm7, Miui(Currently on) and 2 of the new sense 3.0-3.5 roms (Energy and nocturnal)
Kernel currently Tiamat 3.3.7 and I've tried the latest one 4.0.1 or something.
So far i've found the Vipermod kernel undervolt tweak, V6supercharger Option 7 (used before), 3g turbo charge script, and also applying gps fix from Miui thread.
Any suggestions on other tweaks I should flash ? Is myns tweak out dated or needed from this thread? http://www.xda-developers.com/android/tweaks-for-superb-battery-life-in-evo/
I always freeze DRM but with the epic I found other processes starting with SNS to freeze, are these not on the Evo4g? or are they called something different? Also I don't see a System Update process that I used to see on the Epic and would freeze.
Calibrated method I use is charging to 100 percent and just using the Battery Calibrate app in the market. Its the first one that comes up when you search.
Any rom suggestions that I should flash to get better battery life? I need to use my phone for pleasure and work so everything needs to work except 4g and video recoding 720p. I need everything else operational.
Also any suggestions on other battery saving techniques would be greatly appreciated. I've got plenty experience with the Epic 4g but the evo 4g is so old school i feel like this device loves to eat battery way more than the epic when being used and when not being used.
FYI i have a moderate to heavy user.
EDIT: for those who could gain from this post, I'm going to be following Carhaulers recommended settings. Hopefully i get better battery life and everything runs smooth.
GB-evo-deck 1.3d or MIUI's latest creation
Tiamat v3.3.7-SBC aka the "LEE" kernel
Under Clocked @ 128/499MHz <<128/499MHz IS the new 245/998MHz>>
Under Volted @ -100mV total w/ IncrediControl
Results SO far and a Sense Question.
So as an answer to my own Question i've added the following items in my signature for my Evo 4g and I have no idea how this phone is operating so well at 128 HZ - 499HZ but wow its working smoothly. Battery is pretty sweet also. Still calibrating, drained it completely today and am charging right now to full with it powered off. Only time will tell.
I've had the phone off the charger for roughly 20 hours with no use for 50 percent of the time and the other 50 percent I was playing pandora, browsing xda/engadget, and playing 30-minutes to an hour of games. Not bad so far. Its better than it was before. Now this goes to saying i am uving like a mofo and underclocking.
New Question for those who read this, Is there a Sense Rom that will give equal if not better battery than what i'm seeing so far? and does COD tweaks work with sense roms?

The Epic's up to Gingerbread now, as of early November (finally). Froyo ROMs did get excellent battery life... I did like Myn's Warm TwoPointTwo, paired with a Netarchy SBC kernel... An incredible combination. I can still match that on Gingerbread, but Warm was awesome.
