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.

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

I honestly dont even know what kernel i should be using... I dont even know the difference between bfs and cfs

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

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] Question about custom kernels and why we don't have certain features

Is there a reason we don't have things such as under-volt, cfs, bfs, the smartass cpu governor and other things like that on our custom kernel? All we have is over-clocking and under-clocking. Ive noticed many other phones have all those other features but this phone. I'm not trying to complain, Im just trying to see why we don't have these things.

I really don't know. I would love to have smartass and BFS. Dumfuq's is the only kernel for the slide, and all it adds is OC and the interactive governor. I just don't think any of the devs that make kernels with bfs and undervolt and smartass for other phones are working on the slide. It would be awesome if dumfuq could at least get smartass governor on the kernel. I get at least 12-15 hours of battery life anyway, sometimes over 20 hours, so undervolt isn't actually all that important to me at least. The rest would be awesome though. Maybe politely ask on dumfuq's kernel thread in the dev section?

Ill give it a try, hopefully he responds and makes the kernel haha

Whats better no havs with setcpu or havs?

Hey guys, I'm just wondering, after reading around the forum, it seems the general concensus is that using setcpu with a havs kernel is not recommended and that it is recommmended for use on no havs kernels. Thus my question is, for better battery life, is a havs kernal such as netarchy's bfs with havs or netarchy's with nohavs +setcpu the best for battery life?
Sorry if i missed something or my facts are wrong. Thanks in advance.

It really depends on your phone. Every kernel works differently on different phones. However, the BEST battery life (to my knowledge/experiments) can be obtained using noHAVS and the Collin battery tweak. It essentially does all the work for you (instead of tweaking SetCPU). However, Netarchy is pretty much a boss and ALL of his kernels are written so that your battery life will be awesome. It's really about trial and error with your specific phone

alright sweet, thanks for the reply

Swyped From Eva Running Myn's RLS4.95 On The Now Network!

after trying to get decent battery life for a long time using SetCPU and Juice Defender combined with other kernels I have finally ditched both of them for the Netarchy more aggressive superior battery charging 4.2.2 v2 kernel with HAVS. I have never been more satisfied with my battery life (well on the Evo that is lol).

Battery Kernel

I just rooted my DInc today and I heard about a kernel that ups the battery life. Is there such a thing, and if so, can someone point me in the right direction? Thanks in advance

Most kernels try to improve battery life. Are you running a sense rom or aosp rom?

If you're talking about Savage kernel, be careful... that thing uses an SBC (super battery charging) mod that can potentially harm your device in the long run. I personally am using VirusROM 1.5.1 with its stock kernel and have seen better battery life than SBC, but that's just me.

With this kernel my battery quite literally does not go down when it's sleeping (screen off), unless I'm in an area with bad reception. Screen on is also somewhat better than stock - it's hard to improve screen on at all, since that uses the CPU pretty aggressively. However, it does use improved scaling to always try and minimize the CPU load while keeping performance up. All that + HAVS (Hybrid Adaptive Voltage Scaling, which lowers the amount of power the CPU is drawing) = win battery life

The superior battery charging kernals will not harm your device, but instead may shorten the life of your battery over time. But at 15 dollars a battery, some believe it to a negligible side effect. Its all personal preference, really.

If you're sticking with the stock ROM then search for a Sense based kernel, then read the OP and associated reviews in the comments following to learn how to install it, current features (what works and what doesn't) and any other possible info you'd need.
If you're planning on installing a different ROM, those already have kernels baked in, so give that a shot first and then try other kernels if you feel the need.
DInc/XDA App

I've had EXCELLENT results with the kernel from Myn's Warm TwoPointTwo RLS5 (NOT 5.2)
I forgot which one it was though... D: I think it was the ziggy 12/19...?

Kernels for Battery
I use the Newest Ziggy Kernel (BFS) with SetCPU set at conservative.
=Great Battery life !!
This kernel also enables other options like SmartASS and Performance, but conservative is a winner for battery life.

[Q] Fuel Effecient VS High Powered

Well we all know that some ROM/Kernel/Radio( R.K.R. for the rest of this post )setups have benefits and draw backs, usually pertaining to battery life versus function. I've yet to find one that is the best on both. I know of some arrangements that are balanced, but never full blast on both. What I would like to start discussing here are different RKR arrangements that have created either a high speed environment and those RKR setups that extend the battery life significantly. Being both a traveling person and a nerdy techi enthusiast , it'd be nice to know what I should use in my phone to allow me to listen to music / movies/ simple games the longest for 8 hour flights and what I can do to really enjoy my 3D gaming without any lag for when I don't care about my battery life.
Your thoughts?

I have good luck with the following:
ROM: CM7.0.0
Kernel: SavagedZen 0.0.1 BFS
Radio: 11.19
Also, I'm OC'd to 1.152 GHz and am using viperboy's undervolt mod at -100mV.
For me, this results in great performance and very good battery life (at least for the last day or two, during which I've made it a point to stress it and see how it runs).

1) The kernel: Some say that SZ is a ripoff of Tiamat.. I don't know if that's true or not, but I've had better luck with SZ, so I run it.
2) The radio: If you've never flashed a radio, be careful and read the instructions in the thread closely.
3) As far as OC'ing, CM7 has that built in under the CyanogenMod Settings menu, no need for SetCPU.
4) Undervolt Mod: I was one of what seemed like very few people that got the -100 undervolt to work.. if it is not stable, try some of the others viperboy has posted.
Good luck!

On a side note of this make sure whatever kernel you choose uses havs. A large group of people seem to be doing just fine with -50 voltage script. Radio can make a difference also. I'm currently using and have had the best luck with the 4.08 radio.
These are just my opinions, there what works for me. However not two phones are alike. In the end I'm sure you'll find your perfect setup.

So what does undervolting do? I am assuming it reduces power consumption yet at the same time you are over clocking. It seems like two factors that'd defeat eachother. However, again, it's why I started this thread is to learn more techniques than I already know.

I am fairly sure the downloads are gone saddly. Any chance you still have the downloads for the SV? And from your experience what's the difference between Tiamat and SV?

Yes, it does reduce power consumption. I'm pretty sure the reason that it works to OC is that all the undervolt script does is change the max draw of the CPU at any given frequency. So even though I'm running at a faster clock speed, the new max voltage draw at that speed may be lower than my previous max for stock clock speed.

Yeah, I kinda figured that might be the case, but I wasn't going to rule out the POS computer I use for work. As far as why I run SZ instead of Tiamat is that the one time I tried Tiamat, I could not get my SD card to mount to my computer, despite the fact that it had been mounted just five minutes prior in order to put the Tiamat zip on for installation... After that, I gave up on Tiamat and don't bother trying it anymore.
Also, I have attached the zip of SZ for your flashing pleasure.

Which undervolt level(s) did you try? Please keep in mind that like I said, most people haven't been able to get very far with -100 or -75mv, so I am a bit of a rarity in that regard.
If none of the undervolt mods work for you, I'd advise posting in the thread and seeing if viperboy has any ideas; he's been very supportive if people have issues.

Well none of the other downloads work *cries*
Are there any other "Undervolting" kernels or mods that you know of? I know Hydra is supposed to but their site doesn't work, it seems to have fallen off the map. Ideas?

Some kernels are undervolted as part of their design. invisiblek is one of them, and I know a lot of people run it. You might give that a shot.
Also, if you mean that viperboy's links are down, it might be nice to message him or post and let him know that if he does not already.
