I want to overclock my phone. I have doom kernel v14 installed. I installed no frill CPU on my phone. The min frequency I seleted was at 300 MHz (approx) and the max was 1.4 GHz (approx). Does this mean that the phone will automatically go between these values if I run a heavy app (eg GTA 3)? And what does the 'governor' and 'i/o schedular' mean and what does it do? My current settings are :
sio - I/o schedular
Performance - govenor
Min - 245
Max - 1.2 Ghz
Governor : Smartass v2
Mine is like this.
and what about the i/o scheduler? And what does govenor and i/o scheduler mean?
I'm also on Doomkernel v14 and my battery is draining so quicky. Its dropping 5% every 10minutes even when I'm using any light application. I have SetCPU and my sttings are Max 1401MHz and Min 134MHz with smartassV2 and deadline. Although speed is amazing but battery performance is terrible.

Performance governor is a "special" one in that it goes to the max. clock speed, and never uses the min., or any frequency in between. You can do that if you want to do benchmarking reliably, but I'm not sure it's good for battery life.

^ That page explains all the governors, but from what I can tell from using Cool Tool onscreen system info app, "lagfree" on Doomkernel seems to be a higher performance governor like you'd expect from the name and not how he or she describes: it seems to scale down only quite slowly from a high clock, I'm guessing to eliminate any possible lag while scrolling the interface that might result if it scaled down quicker. And we don't have anything relating to multiple cores
Anyway, I think I saw you say you were on JokaWild as well. Looking at the Joka init.d scripts the SmartAssV2 parameters are tweaked towards performance and it comes as the default for the rom, so maybe try that as a more balanced option than Performance governor.

I wondered as well if v14 was not as good as v13 3013 for battery life, but better for performance, but 5% in 10 minutes is a lot. Have you tried using the BetterBatteryStats app to find an explanation? Has it got better just through subsequent use / recharging?
Battery life really sucks on jokawild (actually in all CustomRoms).
I have mine like this (r800a):
-smartassv2/sio or bfq
-.62 stock rom with a couple of build.prop mods
-64 baseband
-juice defender
-brightness around 25%
-supercharger v6
My phone has been for like 4hr and still with 100%

Was it charging? That's impossible. I left my phone idle,lowest brightness and wifi off for about 30 minutes and it dropped to 96%.
I have deep sleep enabled,juice defender,

First off:
Rom:

Kernel:
1.8ghz bolted BFS uv kernel
if you overclock, your battery life is less. more power = more usage
so, in theory, if you underclock, less power = less usage..
when I'm at work, I barely use my phone. Maybe to text or a call here and there..
So I wanted to improve my battery life as much as I could,,, I have SetCPU and I have the minimum at 350mhz and the maximum at 650 using the smartass governor when not in use.. Since this is underclocking, the battery life has improved drastically,, though is it safe? I don't see any reason why not, just though I'd like some input on it.
Yeah, you're fine. With the Smart-Ass governor you don't really need to underclock. It's called smart-ass for a reason. It will only use as much is needed. So when your phones screen is off not running any tasks, the governor will underclock itself.
Another thing to add is if you are using SetCPU, then you really do not need to set up any profiles that would underclock the phone if you are using smartass.
question... I see all the govener setting in ns tools, setcpu, ect.... just wondering something.... What setting is.used in factory otu roms? lets say a.unrooted nexus s, what is.it natively set at? 100/1000 ? and ondamand? or is.it 1000/1000?
Sent from my Nexus S 4G using XDA App
100/1000 ondemand is the default.... but I always change it to 200/1000 smartassv2 it works best for my phone

I usually use "ondemand", it seems to work best. Once I decided to try "powersave" and my phone slowed down to a crawl, pretty much unusable. I don't know what that was about, but I definitely don't recommend it...

Powersave limits the cpu to the absolute lowest frequency at all times. It is not usable for normal operations, except for Setcpu screen-off profiles.
Performance governor is the opposite ; it keeps the cpu running at max frequency (1ghz with stock kernel) and is useful only for speed benchmarks.
The other linux kernel governors are described in detail in numerous threads... All you have to do is search "kernel governor ".
My personal choice is smartassv2 since it's responsive, efficient with battery consumption, and features a screen-off sleep profile.
Ezekeel recommended me lazy with proof screenshots
Governors control how the CPU frequency adjusts. They work like this:
Ondemand: Starts at a low frequency and when there is any CPU activity it uses max frequency. It goes back to low over time.
Conservative: Like ondemand, but instead of using max frequency on CPU activity it uses the next step. It's less responsive than ondemand since it goes like: "100% CPU > Higher Freq. > 100% CPU > Higher Freq..." instead of "100% CPU > Max Freq."
Lazy: Like ondemand but there is a small delay between frequency changes. I use this one.
Performance: Max frequency all time.
Powersave: Min frequency all time.
Interactive: This is a bit complex, actually it's sampling the CPU usage and trying to predict what will come up (I think).
Smartass: It's like interactive, but rewritten. It should give better results.
Default is ondemand 100/1000 and it works pretty good.
Hope I helped.
Hey what are the best battery saving + good on performance settings for air kernel e. G governor and scheduler and btw I'm using slim ics 3.5 so is there any better kernel for battery saving.
P. S I'm running lion heart noop atm with 100/1200 and not too sure if it's killing batteries or not..

My suggestions:
use a lightweight, stockish kernel
---> slim ics is a fast, streamlined ROM and coupling it with a heavily modded kernel may only burden it with unnecessary overhead, so i recommend using stockish kernels like Franco's, _thalamus', or Pete's
play with the right governor-scheduler combo that works for you
---> if you're vent on using Air, you have to try out the different combinations that will work for you. Every phone is different and your phone has its quirks and strengths. When I used Air, I used a noop-lazy combo as this gives me the best battery life and performance when I need it, but this may not be true for you. So experiment and benchmark. This is what makes Android special: the power of choice and customizability.
Cheers!
go for the air kernel weekly 4.0
smartass v2 with noop scheduler and deep idle on .. works smooth and amazing battery life ..

+1 smartassV2/noop. New Weekly works also flawless.

What would you consider amazing battery life?
air 4.0 [Only Voodoo Colors (Original)]
with 400-1200mhz cpu freq ,deep idle on
smartassV2/ noop is not stable for my used.
have no reason, reboot random ...
try to ondemand dadeline
200-1000 cpu freq , deep idle off,
I think this is helpful

Your overclock isn't stable then.
It's a not a "per use" thing. It is just as stable as ondemand with deadline.
I had my best experience with
ondemand (lower the up threshold to ~85% via nstools, than it's smooth as butter)
200-1000 Deep Idle ON (ensure that deep idle works properly with TOP=OFF)
Deadline
Just wondering what changes I can make in Trickster Mod for the first gen Moto G for the best battery life? Currently only have the sd card read ahead changed to be a bit bigger and the CPU frequency set to conservative (don't see an option to underclock GPU).
I found that ondemand and noop worked best on stock kernel for me.
Ah okay I'm using Faux123 kernel for 1st gen (dunno how this one rates in terms of battery life) and it gives a few added options like intellidemand though I'm just on conservative and cfq.
I find that even when I put it on something like intellidemand or conservative, it either uses the 300 mhz frquency or the 1.19 Ghz one rather than using some of the other lower ones much unless I limit the maximum to 998 or something.
I'm using no frill cpu on a stock CM12 ROM with ondemand and noop. Based on the cpu stats, mine also spends most of the time at either 300 or 1.19.
Just curious out there on what everybody is running their CPU frequency, governor, and such, Just looking to see all my options and how I can save battery and increase performance
You won't decide anything until you try. The freq and other settings are highly subjective. As per my usage, i can even survive on 1497Mhz and the phone would still feel buttery smooth, but i use 19xx Mhz step. GPU at 389Mhz. Using default SAOSP kernel with alucard governor + hotplug and the system is performing like a nexus device.
