While I could link, I'll throw a few quick comments up for quick reading...please note that generally I follow the following pattern when chosing a kernerl
First
SBC or No SBC - SBC gets alot of bad rap, all I'm going to say is that I've been using SBC kernels only for months and haven't had a single issue. I've found that actually having my phone at 100% when I take it off the charger really makes a difference during my daily usage. However do your own research and make your own decisions on this.
SBC kernels have a trickle charge tweak that powers on and off to keep the battery at 100% instead of the stock kernel which considers "Full Battery" to be between 90% and 100%, this is why when you plug in your phone from a full nights charge, that it may discharge 5-10% within an hour. No SBC would be stock charging
Second BFS/CFS (I don't really know how these function, but my lamens take is below...)
CFS (Completely Fair Scheduler) - Use this one, it's the most friendly and stable and is my preferred choice just for stability reasons
BFS (Brain **** Scheduler) - Faster burst readings on various speed tests, but often doesn't play well with many phones, less stable but possibly faster.
Third (Havs, Less Havs, More Havs)
Havs or Hybrid Adaptive Voltage Scaling - adjust voltage to cpu depending on certain conditions of the phone, this generally helps battery life as it won't provide full voltage to the cpu when not needed. SVS which is not usually listed in kernels would be standard or stock, and if no HAVS or other Under Voltage is listed then this is likely the case. Less havs, means "Less aggressive scaling, More would be more aggressive scaling. It is not suggested using a overclock program as this can cause worse battery life as havs may work harder when you fluctuate the cpu speed with a program like setCPU. Go with less havs if unsure.
Optional
UV - Undervolt - a static undervolt that does not fluctuate.
Smartass Kernel - basically lowers cpu when the screen is off, this would help battery life, Less/More applies similiarly to havs.
Enjoy, Net's new 4.3.4 is very stable - I'm currently using 4.3.4 - cfs - nohavs - suv - sbc, with Koni III rom. I've had a couple of random reboots but otherwise it's sittin pretty. I'm going to try a less havs tonight to see how it affects battery. I try to carry and extra battery or charger so I don't have to stress and can use my phone to the fullest enjoyment. Stressing over to many little things ruins the fun. Don't worry about everyone else, flash away, almost all mistakes are fixable.
Can someone please suggest an overclocking range for use with setcpu? Id like to gain some extra performance and dont mind a higher battery drain,but I am concerned about going too high and cooking the tablet
Any suggestions would be appreciated, thanks!
i believe you need a custom kernel or ROM to overclock; SetCPU will definitely let you underclock just rooted.
Once you have a kernel w/ OC enabled, I'd suggest starting with 1400MHz, then load a cpu-intensive game & play for 30mins or so. If SetCPU doesn't show the temps going north of, say, 110F/43C, increase the max speed by 100, repeat until temps get past your comfort zone, then drop back to the prior setting.
I was unable to find a max suggested temp range for Tegra2, so you may want to err on the side of safety and/or comfort and aim for a lower max temp.
As stated above you need a custom kernel to overclock, but it isn't rom related at all. I have been running mine sense i was able to load a custom kernel at max freq 1,504 Ghz and min 216 Mhz and have never had a problem at all. Using setcpu you can set profiles to save battery life, like screen off profiles and also use different governors to help battery life. I usually just leave my governor set to ondemand and can't complain about battery life or over heating.
thank you to you both! Much appreciated
hi
i have a htc evo 4g running android 2.3.5 and kernel 2.6.35.10-g4b48446 [email protected] #1 and i have a few questions on setcpu. its a stock rom and it is rooted.
I shut off my profiles and disabled the perflock - it said success. So i ran the long bench test and only got 2078 ms, not 5000. so i dont know if its really working. I reengaged the profiles and i think it works with the screen off. the rest of the time i am not so sure. in fact it seems to still drain fairly rapidly unless i turn on some battery saver or something. I have the following settings on my profile all are set to ondemand except charging which is set to performance. the only other setting i can choose is user
in call 998 max and 245 min priority 91
screen off 384 max and 245 min priority 88
charging any 998 max and 245 min priority 85
battery <25% 460 max 245 min priority 81
bbattery <50% 883 max 245 min priority 65
Temp> 42 C 614 max 245 min priority 50
what am i doing wrong? I have it enabled and i have notifications off
i have system panel to try and monitor but its not recording and it also drains the battery like crazy so i think thats set wrong as well but i dont know why.
i also tried juice defender but it doesnt work right because it says the AOSP file isnt found in the system/app folder. I looked there and also in teh data/app folder and its not there. So i dont know what to do about that.
thanks
stock sense is just not all that efficient really. (well thats my opinion) profiles seem to look ok but also finding a different kernel with different governors (smartass v2 is rather efficient and changing around the frequencies as needed)
auto sync settings as well? turning some stuff of that you dont use or look at and so on can help too
and calibrating battery a bit can help aka a full discharge a full charge and full discharge will sure help (also what i have found personally)
kernels
thanks for the reply. You mentioned different kernels. I understand about rooting my phone but not so much about how to load a different kernel or different rom. Where do i go to learn about that?

look around in the development section as there are some great kernels available right now...Ca1ne just released a new version of the underworld SBC v6 that i personally like with great battery life ...Mason kernels are also great with great battery...just make sure u read the threads completely to make sure u are using the right kernel for the rom u are using...ie there are kernels for ics...sense....and so on......also the kernels load through recovery...just load kernel to sd and wipe cashe and dalvik and flash zip...hope this helps...Carp
Hi another question about kernels. I am a bit of a newbie other than rooting my phone so i want to understand what advantages/disadvantages different kernels have. You mentioned smartassv2. i have seen others like
chopsuey kernal
freedom kernel
golden monkey kernel
savaged-zen kernel
tiamat kernel
all of these i think support sense roms.
as i understand it , you have to go into the recovery screen and load hte zip file off the sd card and reboot with the new kernel. What are the risks/rewards of doing so? I guess i am trying to understand which one would suit me best.
i have the current sprint lovers rom i guess since it is factory stock so should i also be considering changing the rom? Maybe i am getting ahead of myself here.
thank you again.
which rom are u wanting to run....this will help us steer u in the right direction
im sorry your entire post didnt load on my end i see ur running sprint stock....that is a fine rom but i have not ran it myself....
---------- Post added at 01:53 AM ---------- Previous post was at 01:36 AM ----------
i personally have switched to sbc kernels when they came out with a sense version...i am addicted to sense 3.5...just my personal likings...sbc is superior battery charging whichcarp will give u better full charge on your battery so when the light turns green and u unplug it it wont drop down to like 90% battery in just a few mins....i can squeeze another couple hours out of my battery with sbc and even more depending on light usage....but u will stil need to play around with different cpu speeds like 786..921 and so on to see what your individual evo can stand....what works for 1 may or will not work for another....lags and bootloops etc...
You don't need to change Roms, you can if you want, but changing kernels will unleash new features. Some features are:
Full hdmi mirroring
The ability to over/under clock CPU
2 way call recording
Improve battery charging
Enable swap space
Improved performance of phone
Some kernels allow under volting CPU to further save battery (this can cause some stability issues so start slow with undervolting)
You may want to take a look at Lionfish kernel also, just note first boot may take a while.
Also ditch the profiles in set CPU, I tried profiles and it never seemed to work right. A good governor will handle all your profile settings.
I like smartass, and intellidemand the most on my set up.
As an idea ok the battery life I am getting, I streamed Pandora over 3g for about 8 hours not much other phone use, screen off most of the time, and my phone was at like 20 %. I thought that was pretty good.

thanks detcup4evr for helping out explaining that better...i blew out my back and between no sleep and pain meds the brain just dont want to fire...thanks for stepping in bro....carp
smartassV2 vs InteractiveX ... which one giver better performance AND battery life??? currently I am running LIONFISH 1.8 with interactive X
Using profiles in setcpu actually uses more battery life. Because it has to be running all the time and monitoring phone state to know when to change to a different profile.
interactiveX vs smartassv2 all depends on how you use the phone and really which kernel it is. I've noticed little things like on mason's I got better battery with smartassv2 but on other kernels I get better battery with interactiveX. As far as performance, you won't realize a difference.
ok so it sounds like i should try the sbc sense 3.5 kernel with the smartassv2 governor. Did i get that right? i will look around to see where i can download that.
Were you refering to this kernel?
Underworld Sense Kernel v0.6
yes this is the kernel i run with ODJDub HD Bliss!! Sense 3.5...if u choose to run this rom it will give u alot of different options of kernels and apps and other things from the installer....if i can help u more just feel glad to hit me up....carp
Ok so with lionfish 1.8 kernel and interactivex, I should not use a profile? What does CPU go to on screen off? also where does it mention profiles use battery? I'd like to read more into this..
Thanks

Sense rom with Underworld v 0.6
At Carp -
thank you for the advice. I was thinking maybe i would use my ROM still (its a sense i believe) and load the underworld v0.6 kernel with sbc and see how that goes. I havent done very much research on ROMs so i dont know that i want to get that deep into this just yet. It seems like underworld has alot of nice features. One thing that i am wonderig though is with the new kernel would have any further ability to unload some of the sprint bloatware or do i need a new rom to do that or is there another way to do it? Things like qik video , gmail, accuweather blockbuster etc all load themselves periodically. I kill them but then they come back like weeds. Even programs i do like , like pandora, wheres my droid etc come back also. But i dont want them to.
no u will be fine getting rid of apps and bloatware u dont wont...u wont need a special rom....i use a free app in the market called root uninstaller to get rid of useless bloatware,apps etc...then u can go in and manually uninstall what u don't want...be careful not to uninstall anything which the phone needs to boot and operate such as android system...you will see the things u are looking for when u load the app...hope this helps...carp
I actually did something unusual.
I have universal aggressive lionfish SBC 1.8, swagged out stock N, and smartassv2
I set the ideal, sleep, and wake freq for smartass v2 to 128, while setting the up rate to 245. I used set cpu to lower the min freq for my device to 128. I set max load to 100, and min load to 85, and down time to 0. I then set a profile for "ondemand" during screen off, of 128-384.
I actually have pretty awesome battery life (I'm an uber heavy user).
Sometimes it reads that I spend over 70% of my time at 128mhz.
I feel no lag. It clocks to 998mhz maybe 15% of the time, mainly when loading web pages.
flashed underworld v 0.6
Hi Carp,
well, i flashed the underworld v 0.6. So i see in set cpu that i can underclock to 128 and overclock to 1228. however, i slid the slider over to 1228 by accident and it froze the phone even though it says its still at 998 mhz. then it rebooted by itself. so i guess that wasnt a good idea. Anyway, theres a ton of governor choices now in the profiles section. i am not familiar with alot of them but i was wondering which of those would provide the most benefit. they are as follows -
ondemandx
interactive x
intellidemand
smartass
interactive
conservative
smartass 2v2
performance
along with ondemand and user space from before.
thanks
Good to hear....u will need to try different settings as each evo will be a little different...ie.. some can take alot of overclock and as u said when u went to high it locked up......my evo likes min 245 and i dont go very little over 998...mine does not like high overclock....i run between 768 and 998 or until i can see a lag or slow down in performance..depends on which rom i am running...i like ondemand x and smartass 2 on my evo but there is a good read in papa smurph's smurphed out v6.6 thread in development on governors and such...go to post #2....i wish there was a perfect setting i could give u but u will have to see what your evo can take...part of the fun of android.....carp
Governors
Thanks carp. I guess experimentation is the only way to know. i charged my phone last night ad i noticed that it does take alot longer to go from 100% charge to 90% but i also noticed that the phone temp was at like 110 deg F and a voltage around 4.263 or so. i have read some thread where they claim its bad for the Lithium ion batt to be over 4.2 V but as soon as i unplug it it drops to 4.1 something usually. I am using battery indicator app to measure it. i am using the underworld w/sbc kernal currently but the voltage being higher has me a bit concerned that i am damaging the battery kind of like pumping water into a jar with the the lid on tight til it bursts. Or in the batteries case - too hot i guess or until it plates.
Can you guys give me the best GPU govenor for any kind of rom? thanks!

That'll depend on what you need your phone for.
If you want all your cores to run at max speed thereby maximizing performance on games and browsing pick the performance kernel.
Otherwise for normal usage just pick the interactive governer.
There's a lot of governors available but these 2 are the only ones that are important and actually useful. Major kernel developers only give support to these 2 governors as they are the most useful when compared to others.
Dont use any battery saving governer. Trust me, your phone will slow down and make it unusable.
Hope this helps!
Best for what?
Governors are built into the kernel, so if you want choices, you'll have to flash a kernel that has those choices. Some are for high performance. Some are for saving battery. And then there's ones in between. Some might work better if you underclock or undervolt to save battery. Some might work better if you run only 2 cores. Some have better wake-up speed from sleep. "Best" depends on what you plan to do with your phone.
Don't forget about profiles either. For example, I've been playing around with HellsCore kernel and HellsCore Manager. You can create profiles depending on what you're doing. Like, if you're plugged in and playing a game, set it for max performance. If you need it to last as long as possible, limit the max clock speed, run only 2 cores, and use a battery saving governor. With HellsCore Manager you can even mix it up; Performance or normal until battery hits 50% (or whatever), and then switches to a battery saving profile. Pretty nifty.
Hi there.
I have problem with battery drain and my CPU have 90° C. I want to underclock CPU. I want to have small ROM with CPU over/underclock but I don't know which one it is. Please help me.
Thanks
CPU Over/underclock is mostly kernel dependent.
With that in mind, pretty much all kernels available for this rom have the posibility of underclocking.
But if you want overclock then only Hulk kernel offers that.
If you want a small rom you might try SlimLP. I haven't ran it myself, but judging by the name it should be slim.
Another to try would be SaberMod CM12.1. You will have to download Kernel Adiutor, or another kernel tweaking app, for this one.
