hi all which governer and I/o scheduler settings use for great battery life ? :/
Hello @absolute1543, in my experience different governors are the best for different people due to different usage. If you're a heavy gamer, I would suggest Performance, considering it'll stick to the highest frequency to process and render the game. This governed doesn't have any toggables or anything of that sort, so it'll save battery by not checking the usage of the CPU of the phone, checking costs battery. If you're a light user (Web browsing, email, no Facebook, etc.), you might want to use zzmove, luzactiveq, or hotplug.
For IOs, I'm not really sure. Google is your friend.
Again, these are just my recommendations, you should do some research and test each of them out before finalising on a governor or IO.

Click "Thanks" if I was of any help!
thx for answer bro

Last time I had installed SetCPU, I couldn't get it to work. Looks like it's been updated to support Tegra processors, and now works with the A7. It doesn't give you a choice of governors (guess the kernel doesn't support it), but you can underclock and set profiles.
I haven't had a chance to play with it enough to tell for sure, but I suspect that underclocking will help battery life. I'd be interested in finding out others' experience in this regard.
Jackpot. I was hoping this would get solved. This may be the key to unlocking another hour or so of battery life.

Have you gotten a chance to play with underclocking and profiles yet? Any results on improved battery life?
I haven't done any formal testing. Subjectively, it does seem to last longer on a charge. I have been playing with the settings to see what would be the minimum acceptable speed for flash video and found that at 450 MHz it still plays reasonably smooth. I wouldn't expect any miraculous increases in battery life from SetCPU since the processor will run at the slowest speed it can while still meeting demand, so if there is not much going on, it will run at 200 Mhz or so.
So, if you are watching video non-stop, I would expect a significant increase in battery life at the expense of smooth playback, but if you are just typing email, I don't think there will be much difference. Still, any gain is worth it.
Hello everyone.
I am looking for a relative best rom and kernel combination for daily use which focus on heating and battery life.
I’ve tried AOKP38 with franco185 and did't change the setting of CPU model. The temperature raised to almost 50 degree. I only open the instrgram and twitter for 10min.
I also tried the slim4.0. The heating is much better than B38 with franco. But battery life seems not good.
Wound you mind recommending the best rom and kernel combination you have ever used?
Thanks! Sorry for my bad English.
I too will like to know. I will be watching this thread very closely.
After browsing through many threads where talk regarding heating issues take place, I'd say underclocking are undervolting are your best bet.
If you don't play any 3D games or do anything that requires some real juice from your CPU, I'd say you'd be fine with underclocking to like 1036 MHz and maybe do some slight undervolting.
If you only want do to the underclocking part, and if you got heating issues with Franco, then try Morfic's trinity kernel.

185 seems to have quite a few problems (see Franco's thread). I jumped ship onto the 181 kernel - wireless tethering (encrypted) works, the GPU is fast enough, and it doesn't seem to overheat. I don't use the kernel for benchmarking (although..... ) but rather, to improve the GPU performance.
And I'm on stock ICS, not AOKP.

I only pay the Temple run sometimes. Does this game require a high CPU?
And how about the battery life on your nexus? The screen on time? 2H?

I changed the franco nightly to milestone4 and now heating is gone, even play Modern Combat 3 us no problem. AOKP with milestone 4 is best for me bro! ;-)

I've been underclocked to 1036MHz for a while now and I've never had and problems running any games. NOVA 3 and similar games runs great. The only issues I've had are when I get a call or SMS. Then my phone starts to lag, but eventually picks itself back up.
Every device is different. What works great for someone probably won't work great for you. You have to try them all to see what suites your phone the best.
There are already many threads discussing this, please use an already established thread instead of creating a new one.

Ok im looking at kernels and im not going to ask "whats the best?" but im really not understanding the difference.
What im looking for is a kernel thats stable (that seems like all of them), one that allows under-clock/volting (and any other batter saving tricks) and one that will work well with my rom (XenonHD rc3) as most of the kernels seem to be using anyrom i dont think this is an issue.
i have been using the stock kernel then tinys kernel but im wondering if Zen or Air are going to serve me better?
Here is the order im looking at things
Stability
battery
speed
cosmetics
From what i can tell the governors dont seem to matter much as long as there are a few available (performance, interactive, conservative, power-saver) and the schedulers are even less important as they can handle normal use just fine. SIO or no-op or CFQ all work just fine for me. never tried FIFO but it seems kinda restrictive when multitasking
So from a development standpoint could someone explain whats so different in TINY, ZEN, and AIR i would much appreciate your input. They all seem to start from google source, are the compiled different?
Ok so i am trying Zen and i like that the CPU can be clocked lower. but im still not sure about whats best for me. A comparrison chart would be grand but i have no idea what to compare
The major differences between kernels are what kernel version they're compiled from, what modules are compiled into the kernel, which I/O schedulers are included, and which CPU governors are included. Depending on what the kernel dev has included, the kernel tends to run better or worse on specific devices. Unfortunately, it tends to vary quite a bit even within a single device line.
Zen is the best one I've found yet for my device. Others swear by Franco, Air, Trinity, etc. It's really a matter of trial and error on a device-by-device basis.
Finally, your statement about governors and schedulers not being that important is a bit wrong, in my opinion. Schedulers are definitely the lesser of the two, but depending on your usage, you can get a little bit of an I/O performance increase by using the "right" scheduler. The same thing goes for governors. A properly tweaked governor can save a bit of battery and/or boost your performance. Just like the kernels themselves, though, it would vary device-by-device and based on the user's usage type.
Ive currently got my setcpu set up to scale the cpu down from max to min dependent on my battery life. I was just wondering what governor/scheduler is the best for battery life? I'm currently running the ktoon gov with the default scheduler which is noop. is this good or bad? what could I run better to increase battery life?
Im not gaming or anything Im just talking day to day internet usage, text, call..Very rarely do I game as I can't find any good games to play thanks in advance for your help!
Completely depends on how u use it. No one really uses it just like u use ur phone. So u just have to experiment with wat gov and what ever.
But if u r using KT747 kernel I would refer to this forum it is extremely informative and gives u preset tweaks if u want balanced or battery saving performance options just take a glance read thru it and hope it helps u out!!!!

Hey guys, just wondering if anyone can help me or point me in the right direction of info to help me choose what's best for my phone....
I'm running kitslim evo5 and doomkernel...
I've got trickstermod installed and have my setup as follows:
Read ahead buffer - 512
Scheduler - fiops
CPU Governer - smartassv2
GPU Governer - msm-adreno-tz
Max freq - 450
My main questions are based around me moving from lagfree to smartassv2 my phone seems to run quite warm but battery is still good??
Also what's good to do with my read ahead buffer etc??
I don't game ever, infact I only use my phone for calls, texts, music and web browsing.
Would I benefit from using zRAM?
I've got trickstermod on "eco mode".
Also my CPU clock speeds and voltage are standard.
Can ANYONE give me some realistic figures to apply to minimise resource usage, power consumption and increase battery life?
When I had my Xperia Ray I had it underclocked quite a bit running gingerbread (I think I was running it at 650mhz!) but it was an absolute ROCKET and underclocking that low saved quite a bit on heat and definitely helped battery without me noticing any performance loss. **I couldn't run the CPU that low on jelly bean at all though it would lag like hell and stutter at the most basic of tasks like opening the app drawer**
I'm hoping to achieve something like this with this phone, or is it out of the question as I've got 4cores and am running kitkat?
Sorry for the essay but just trying to get across all my info and explain as when I try researching it most people give the response "everyone's phone needs different values... It depends how youre using it blah blah"
ANY help/input would be greatly appreciated and met with +1's :good:

That's essentially what it boils down to, it's your Phone so you need to play about with it until you find your perfect setup.

Yeah i was just hoping to get a ball park or rough idea of values that i could start from, assuming that there is at least a few other people trying to do this already

There's a great guide here, which although was written for the Evo, it does list a lot of the governours and schedulers that the Sony has built in.

thanks Didgesteve i have read a few webpages like that :good:
At the minute ive brought my GPU down 2 steps so running at 320 and ive got my CPU clocked at 1.4 and the governer on lagfree as it seems to keep the phone temperatures down, smartassv2 definitely makes the phone (well, THIS phone) run hot
im thinkin that lagfree probably isnt as power saving as i need though, also i turned off ECO mode as this is just for 2 cores apparently.
kept my i/o scheduler as fiops as it seems to be the newest and best? lol i dont really know i could be gettin this all wrong.
had my phone clocked at 900mhz yesterday and noticed a slight drop in performance but for the most part it ran fine:laugh: was a little laggy whilst listening to music and web browsing so turned it up to 1.4, and it runs fluidly :fingers-crossed:
