How to minimize CPU usage when touching screen on Qualcomm CPU.? - Android Q&A, Help & Troubleshooting

My battery drains alot faster when I touch my screen like when I text, Whatsapp or browse.
It's not draining as fast when I simply stream video or watch movies which require minimum screen interaction..
I stream a lot of videos on YouTube and use torrent in background when watching videos (usually downloading the next episode of a a series). And yet my battery doesn't drain as much. I think it's the CPU usage is high when I touch the screen.
I want to minimize CPU usage when touching screen.
In Mediatek CPU devices we can edit etc/perfservscntbl.txt to minimize CPU usage when touching screen. Is there any such file for Snapdragon CPU (S410 in my case)?

Are you rooted ?

Yes my phone is rooted and I have installed both L Speed and Kernel Auditor mod.
Is there any specific settings in those apps which might reduce CPU usage when touching the screen?
I can't seem to find any specific touchscreen related CPU settings apart from Glove mode(which is disabled) in Kernel Auditor mod which I believe increases CPU usage.

Undervolting on Siyah 1.5..2

Hey All,
I have installed Foxhound ROM for ICS and loaded the Siyah Kernal.. The ROM itself is great, I have also overclocked the CPU to 1.7Ghz, But i see some battery warming issues. I have installed NStools as well.
Any recommendations what under volting can i use with this config?

Why overclock,do u experience any difference in speed in daily use,except in benchmark..
Btw an app is installed with siyah called STweaks,it controls all kernel features.read first page post 4-5 by droidphile,excellent guide

Yes I have observed changed after overclocking.. The s3 boots up way faster plus for gaming it showed me real difference specially playing real racing 2 with 1.4 and 1.7..Now I only need to undervolt correctly so I can save on my batter life.. Can we set a custom voltage for 1.7 below stock values??

stock voltage for 1.7 ghz is 1400mv, try undervolting by -50mv to -100mv and stick with one which is stable
use setcpu
keep changing it down in increments of 12.5mv and do the strees test keep doing that till u find a value that works
ps once u've done that let's us know what it is.
1088mv for 1200mHz that's the top freq I use so I never played with the voltages for the freq above it.
Hope this helps
remember thanks if it did

k did the testing for ya
on MY DEVICE (Every device slightly diff)
1704MHz voltage 1288mv (put in 1290mv it will round it down)
if that don't work or is not stable for u then the next step up is to 1300mv .
775 mv for 100MHz .
hope this helps and if it did thanks is only 1 click away.

Thanks Bala, Stressing the phone to -50mv at the moment.. Have you tried at -100mv? whats the result so far?
Also when charging I observe my phone warming a little.. Is that good?

[Q] What's The Best CPU Clock Speed for Daily Use?

Title says it all. What's The Best CPU Clock Speed for Daily Use? At the moment I'm at 1.2GHz by the way. By best I mean highest without burning out ect. Cheers in advance.
Noone will be able to tell you what the best speed for your processor is because of the variations between processors even in the same batch. Besides, define "best"? What's best for you? The most stable? The quickest? In computer industry overclockers follow this rule - keep overclocking until the processor starts to fail, then either overwolt and make it stable or decrease the frequency slightly. Extreme overclocking involves extreme overwolting and pushing your proc. to the highest frequency it can possibly go. Different processors can handle different speeds because of the slight variations in them. Whenever you overclock you should remember that you are shortening the live of your processor and the more you overclock, the more you do it, due to the process called electromigration, your processor will gradually start to "leak" current.
i made 2 profiles.. use 1.5 ghz for games and surfing and 1.2 ghz when i use for playing videos or music..
Sent from my YP-G70 using xda app-developers app
Im using 1.5 Ghz @ 1.3V ( stock voltage) . Runs just fine , get about 2500 points in quadrant and fairly good battery life .
For those, who only uses the music function could go this way:
Set with antutu min 100 mhz max 200 mhz and ondemandx or interactivex governor. Battery life should be very nice. Poweramp was a battery drainer, but since 4 months of using this setup Pamp only uses 2-3% per hour. Battery life @standby is also better.
How do you guys make it to 1.5Ghz?
Im using Chips 1.5 and RJ's kernel..
using setcpu and no frills i can set it to 1.2Ghz..and cant go beyond that as there are no other options..
i've also used tegrak (not the ultimate version) and still the same..
I'd greatly appreciate if someone could help..
thanks in advance!
You guys use some high clock speeds lol. For music and videos you can get away with 200 mhz min to 400 mhz max and have no issues. Web surfing I keep both a 400 mhz and for gaming (like snes and genesis emulator no 3d ) I use 400mhz min to 800mhz max. I use smartassV2 or ondemamd for the governor.

u must use ultimate version of tegrak..i use 1.5 ghz on 1310 mv core and internal 1125mv ..that is just tiny more then stock voltage (1300 and 1100) so i get veru good speed and good batery life...and i dont now how u use player on such low fq and so very slow speed and heavy lag..i use mine on 1.5 ghz and it gets all day no probem and i fill him when i go to sleep..

[ Thread ] Your underclocking recommendations.

We all know that our ace sucks on battery & after finding that calibration is a myth, I was kinda broken The only thing that helps us long on our battery is underclocking. There was no thread for this, so I decided to create one ! So guys, please share your frequencies, governors, I/O scheduler, rom name, kernel used & battery life for varied usages ( less, moderate & heavy ). If underclocking hasn't decreased your performance but at the same time if it has improvised battery life then it's worth sharing ! Help people love their battery that hate it like hell now

Why underclock the whole thing if you can just set a screen off profile? Using the phone while under clocked won't really give much battery. The Ace is a battery hog during screen on either way no matter what clock it's set at. All of you guys use your phone differently so that's why your battery usage varies.

Rom : PacMan Rom v22.0.0
CPU Max : 748MHz
CPU Min : 122MHz
Governor : Smartass V2
Stable and less never heats (which means less crashes)
I use Screen off Profile for underclock, Smartass, around 700 max and 200 min..
Dont use now as I amon ultimatum rom and I am testing it so dont need that but mostly I use these settings and Battery lasts 2 days
I dont play games
After trying out many ROMs and trying various combinations of Clock Speed and Govnors, i personally feel that:
FOR BETTER BATTERY LIFE- Clock Speed: 245 - 787, Govenor- ONDEMAND (am getting 1d 5 hrs battery life with 2 hrs talktime, full time 2G connected and 3 hrs wi-fi browsing using Battery Extender 1.2)
FOR PERFORMANCE: clock: 245- 806, Govnor- SMARTASSV2
To save Battery you can further UnderClock it but I feel 787 is apt.

[DEVS ONLY] Nexus 4 camera recording v0.2 (AVC high profile & LEVEL 4) (60FPS)

Hi releasing a quick kernel to test the camera quality
Compiled for Android jellybean 4.2.1 & 4.2.2
Ive tested it needs more modified but ive activated high profile & level.
For testing the boot.img boot in fasboot mode in terminal via fastboot boot boot.img
Test and post results thank you
Log outputs this
OMXCodec: [OMX.qcom.video.decoder.avc] AVC profile = 100 (High), level = 51, ive changed kernel and set the level to 4 for now.
High profile avc h.264 has been achieved along with changing of profile level upto 5.1.
Now my focus/attention is on FPS attempting to achieve 60FPS recording
This is a quick kernel based off motleys for testing purposes on camera quality so thank you motley!

Since it is for testing a I recommend a
"fastboot boot boot.img" to test without flashing, just in case something goes bad, then you just need to reboot.
Flash went well. Going to try some pics and video and then compare to stock and let you know. Colors need adjusting, does this support gamma changes?

Actually is it possible to enable HDR video? Or is it a ROM-level thing not kernel?
This is awesome news if it works. I followed this thread: http://forum.xda-developers.com/showthread.php?t=2039553
but they seem to have reached a dead end in terms of actually improving quality, rather than just file size. I'm curious how you managed to enable high profile AVC, since the last I heard, it seemed to be locked in the driver somewhere (http://forum.xda-developers.com/showpost.php?p=35804435&postcount=160)
Also, I don't think there's hardware support for 60fps 1080p, only 60fps 720p.

For performance tweaks, change cpu governor to Pegasusq, i/o scheduler to SIO. Since you use dorimanx (it's ok but I don't like it), it already comes with the latest maliv3 tweaks (graphics). Have a try using Pedestre's Apolo kernel and use the settings suggested.
For compatibility, there is not much you can do until developers of the games you are interested in releases updates to improve compatibility with kitkat. If you have ART enabled, disable it since it can make some apps incompatible with android.
Hope this helps, gsstudios.

I don't exactly know what you mean with you cannot play these games, but if the problem is that they are lagging you may want to try flashing "pure performances x Zeno edition" it'd make your phone faster and overcome this problem.
