Performance settings in CM9

Sorry if there's a thread to post this in and I'm completely missing this but....
I was wondering what some good settings would be under the 'performance' tab in settings. I'm kinda worried to mess with them, but i'd like to set it up to optimize my battery for the most part. Any tips?

Well, I don't use CM9 so I can't really give you the kind of answer you're looking for but my guess would be just stick to the stock settings. The people who put that whole ROM together know what they're doing and the settings they set the ROM to run to are probably the best. I could be wrong, but this is just logically thinking.

But remember every epic is different as far as hw goes...then take in the aspect of the user (gamer, streamer, just text/call, etc...) and you really dont have 2 phones that run the same. So im sure the preset settings in cm9 are probably best-for a particular user.

I am moving from the samsung moment and am in search of a new I/O + Govener setup...everything runs so different (better) than the moment. I have yet to be satisfide with a good combo that fits my usage as well has good battery life+performance+stability...ill get one of the 3 here...and maybe 2 of the 3 there...but i want it all

I set my cpu governor on power save.... Still fast and definitely increases battery life. Any other performance setting is really personal preference. CM9 beta3 for liiiiiiffffffeeeddd!!!!

[KERNEL][GPL] franco.Kernel - r17

Hey all. I hate bloated OP's so this is a simple one. I don't post changelogs in here, only when I released new versions so you'll have to search for it.
Just for general awareness this is compatible with CyanogenMod based roms.

F.A.Q.
1. My tablet exploded, halp!
A: I don't answer to problems without a log. The log file is in /proc/last_kmsg. Retrieve it from your device and attach it to your post.
2. This kernel works on Y or X rom?
A: This is one of the worse questions you can ask on my threads. This is a Nexus, it works on every rom you can possibly imagine.
3. OMG BETTARY SUCKZ, IT DEAD IN 45 MINUTAS, HALP!
A: As you can imagine I don't build kernels to decrease battery life. All the battery life problems come from your apps, either Facebook, or Maps, or some Location Service being enabled etc etc. Check your damn wakelocks and fix them, the kernel is not responsible for them.
4. How do I flash this?
A: Reading the OP, theres a reason why I added instructions on it.

What exactly does the thermal throttling patch do?

First! Excited to see your kernel making its way here. Love your kernel on the Galaxy Nexus. Thanks again!

Basically just ensures that after that constant is true the thermal_throttle function call is called.

Joking aside, awesome This was my kernel of choice on the Nexus 7.

AW YEAH!

Yea!!! Now I need to buy a Nexus 10. Thanks Franco for supporting the Nexus 10

What kind of features do you plan to try and add to this kernel?

I see. Sounds good. Overclocking is pretty useless on the Nexus 10.
If you haven't already read around, thermal throttling is a big issue on the Nexus 10 which makes it seem a lot weaker than it is. So hopefully your kernel can cater around that issue.
Thanks!

How? Throttles too much?

Won't boot on aokp. I know the op said cm, but I tried anyways. So for the others that will ask, aokp is a no go for now.
Sent from my Nexus 4 using xda app-developers app

Throttles too easily. Run stability test app on the stock kernel and you will see the clock drop from 1700 to 1500 after a minute or two.

Yeah. When playing games at stock speeds, it'll start to throttle and lag.
People have been fixing this by undervolting, underclocking to about 1.2 ghz, and raising the thermal throttle temperature.

Kernel inquiry

Ive been working(slowly due to work) on a kernel for the lgog. I've been able to do some pretty heavy overclocking but I need some community preference.
Overclocking obviously causes more heat and reduced battery life. Higher overclocks require overvolting beyond required to maintain 1.5ghz set by Qualcomm/lg. Keep this in mind before asking for 2.0+ overclocks in daily kernels.
What top clock are you guys wanting for a performance kernel? Also are you guys interested in a reduced clocks kernel. 1.0-1.2 top clock with a lowered low end clock along with lower GPU and system clocks.
Personally I Dont see a big need in heavy overclocking on a quad core. However I would like some opinions before I release test kernels. I will attempt to see just how far the lgog can go at least once, but that will take around 10-20 test kernels to find the top speed.

I like the idea about under clocking. This bad boys fast already. The battery savings would be nice.
Sent from my LG-LS970 using xda premium

The highest overclock that I would like to see is around 1.7-1.8Ghz even though I don't know what I would need my phone running that fast for. Now the under clocked kernel sounds very interesting .

Would like to see underclocked as well. Phone is plenty fast.

I don't see a need for anything over 1.6. The underclocking idea sounds great though
Sent from my LG-LS970 using xda app-developers app

Just looking at how this governor uses CPU, it hardly uses the middle ranges. Maybe some better governors? Just another thought.
Sent from my LG-LS970 using xda premium

I would be interested in a kernel with A 1.8 top speed slightly lower bottom end and different governors. While 1.5 is fast 1.8 with a better governor along with a 128 minimum speed would be a good comprise kernel

I don't know of anyone having speed issues to warrant an over clocking kernel, seems more for bragging rights.
I think most people would want a kernel that saves battery but doesn't compromise on speed. Also, have you looked into the wake lock issue yet?
Sent from my LG-LS970 using xda app-developers app

I would love to see some undervolting, while maintaining a decent clock rate. Battery life is important, but i love to game too and wanna see consistent framerates.

You won't see a 128 min. I'll be lucky if I get 256 stable, but it is in the works

I'll probably use faux's volt control. This is my first Qualcomm kernel so I've been mainly running through it. The n4 is far far far cleaner. Our source is a jumbled mess to an extent.
Also the other devs have found a way to run n4 stock ROM with kernel. However finding the best way for everyone to benefit is being sought after.

Faster is always better in my book. Pump that baby into overdrive!

and is n4 better?

Something to consider. The n4 if pushed to far will actually brick. Our device might be the same.

Haven't looked but how far can most n4 go I hope it can take at least a 300mhz oc.

Best Kernel for Overclocking Galaxy Nexus

I'm thinking of flashing a different kernel to my Samsung Galaxy Nexus so I can overclock the CPU/GPU. I've noticed that franco.Kernel and Trinity seem to be among the most popular kernels, but I'm not sure which one to choose. In your opinion, what is the best kernel for overclocking and why? FWIW, I have the Verizon model of the phone (toro) and am currently running CyanongenMod 4.1.2, which is based off of Android 4.2.2.

Antutu or CF bench are good apps.. And a warning: overclocking will decrease the life of your phone! Be careful! If you want to use your phone a little longer I wouldn't do it (I wouldn't anyway because I think this phone is very fast especially with Android 4.3)..

Hi,
I've decided to bump this thread because all other GNex OC threads are very dated.
I recently received the extended battery 200mah and I'm ready to overclock. I wish to retain battery life to have screen time 3-4 hour on moderate usage.
I'm current rooted on stock ROM, and I wish to simply stay with stock ROM provided battery life will remain the same (perhaps I have to undervolt)
I want to hit 1.5GHz CPU and 384MHz GPU...which is what the OMAP and PowerVR SoC's true default clocks.
Given my circumstances of stock ROM, which kernel would give me the best stability/battery life? Any kernel that somehow has OC settings built in or do they all require me to buy setCPU?

They all use setcpu or trickster mod. Regarding the kernel you just should try some out.

What type of OC are you running?
Do you actually notice it day to day usage? I cant think of any apps that could benefit from it besides gaming which I do very little of on mobile.
How has it affected your battery life?

I don't OC myself. I want my gnex to last some longer. OC will wear out tour CPU.. I die it once for a day maybe two but didn't notice any improvement. I was at 1.5 GHz or something.. I think it may have some speed improvements but your battery will drain like a maniac. If you don't game I suggest you underclock: even more battery life with no speed loss!!

Kernel feature ideas

Hi fellow HTC 10 users,
So I've been using the HTC 10 long enough that I know the current state of custom ROM/kernel development. Now, I have some interest in kernel development.
Anyone have ideas what features they would like to see should everything go ahead? I will of course include the standard CPU governor, IO scheduler as usually.
Cheers, Saber

I have always wanted the vibration to be stronger. I have seen ROMs with this added as a tweak but not sure if it can get even stronger. I'm sure I'll think of other items in time.

I'm currently using cleanslate/leedroid and it seems this can be controlled via a voltage slider. Not sure what the limits are with our device, but will see if some of the tweaks already allow tweaking to the max safe limits

under volt
will help reduce the temperature
