can i turn off s600's cores ?

hello
can someone help me ?
can i turn off s600's cores ?
from 4 to 3 or 2 cores

HTC One doing this automatically. Install CPU-Z You can see in this app activity of your cpu. In daily use most time Htc use 2 cores or 1.

Honestly there is no real reason to do this. Like xnobex said your device does this automatically to save battery. It only uses as much processing power as it needs to so its never at 100% load all the time and if it was it would be killed quick and overheating like crazy. Doing this would only mess up the experience and cause lag, with very little to show when it comes to improved battery life. Your device rarely ever needs to use a lot of processing power unless you're playing games. Your best bet is just to lower clock speed which the power saving mode does already setting it to 1.2 GHz when its normally at 1.7. Personally using custom kernels and under clocking helps my battery life. Also greenify is a life saver.

Is second core of Xperia V disabled?

Hello,
Is XV's second core disabled in default? In trickster mod I see "core1: disabled"

Nope.. The second core is used dynamically whenever additional cpu power is required. And in the times where one core is enough, core 2 goes "offline", which might be detected in your app as "disabled"

I have made the same observation.
But it is a valid question. It's a documented trick to disable cores in multi-core CPU's, and only have them triggered by benchmark apps. At least German magazine CT was unable triggering multi-core operation under normal usage. Only when certain benchmark apps were used the other cores jumped in. Another case is CPU speeds, where they throttled the CPU frequency for getting good battery marks. They never managed to induce max speed, only benchmark apps did that. In particular Samsung mobiles have become infamous for that.

[Q] Havy Battery Drain on [ROM][4.4.2] CyanogenMod 11.0 20140315 [DAILY] [FULLY WORKI

HI I am having heavy battery drain
running version from 15/03/2014
I had a maybe 3 minute phone call but still the phone app has eaten up 37% followed by 31% android system
total 72% left after 1h36min
This is a new behavior, up to last week it all worked smooth.
the CPU governor in nofrills CPU is now set to performance since on demand or power saving make the phone very sluggish
Also Video app is not working, just crashes same result in Focal
Any ideas or tips?
Thanks Merlin

You do realize the performance CPU governor makes the CPU constantly run at 1 GHz? This will of course drain your battery.

It's maybe the 1GHz bug. The 1 GHz bug cause the heavy battery drain. Try this, turn off wifi and reboot.

its 1ghz bug if you are using ondemand. but i hope you know performance governor keeps cpu freq. at 1000mhz.
im using abbysplug/sio governor. and my battery lasts for 18 hours.(wifi or mobile data on. sms Messaging. whatsapp. facebook games rarely)

abbyssplug change the processor performance. You can find it in Settings > performance > processor > CPU governor

go tp settings>about phone and press repeatly to build number. you will see "you are a Developer now" text. go back. performance menu must be appear. you can set it there cpu governor.

A fellow user thankfully redirected me to this thread and told me about this governor setting you mentioned above and i must ask you some questions if you dont mind of course
1- What's the difference between Abbysplug and Powersave governor? I have my phone underclocked at 200 at all times and the sluggish speed never seemed to bother me much, so is there a difference between these 2 governors when it's at 200 all the time?
2- Have uninstalled/frozen/disabled any system or built in apps?
3- You leave the mobile data on for 18 and the battery lasts????
Please give me your exact settings, man; i'm desperate. :crying:

QUAD Core Question

Is there a way to disable cores individually to save battery life? I don't need to continuously use the quad core in this phone. I've searched for applications but everything is old... back in 2013... any help or advice would be great.

as far as I know the phone already does this on it's own
the cores are only active when needed. power saver mode turns off even more stuff. if you want complete control of all the cores manually you need a custom kernel (ElementalX) and software to control it

1GHZ bug in stock ROM?

The last days my girlfriend is complaining about battery drain in her i8190. I installed No-Frills CPU and it seems that the min CPU frequency is stuck at 1GHZ. Applying the 200MHz setting does nothing, when i restart the app i see that the min freq is 1ghz again. The phone is with stock rooted firmware (XXAMJ3).
Any ideas about this really annoying problem?

Thanks for your answer but i am a newbie fish i didn't understand that. What am i supposed to flash?

@volanis1980
Tell your girlfriend, she should reboot her phone with Wi-FI OFF. This will solve the problem

Did you or your girlfriend change the CPU governor to performance? No-frills CPU control can change the CPU governor. Try it out
Or
Set the phone in airplane mode and reboot the phone if it still didn't work then please attach/send some screenshots from the battery statistics in settings > battery in this thread.
P.S : Download "CPU spy" from play store and check if only 1GHz is in use.

She hasn't change the cpu governor (was with ondemand). The trick with airplane mode didn't work either!
These are two screens from no frills and cpuz where you can see the problem. I checked yesterday the real battery performance, it didn't seem that bad. Was 100% to 35% in about 9 hours with 2 hours screen on time. But isn't that strange, the min freq bug?

that is an unnormal behaviour. I think it is app-related.
try THIS to see which apk´s wake your phone up.

I installed wakelock detector but i don't see something strange.
Really frustrating, i can't find any solution!

noLED 107x (a playing tool in my opinion)
Handcent 104x (stoneage)
... many wakelocks
btw who uses sms in this time ?
use threema and greenify noLED
m.

if you still have problem try to change govenor and i/o schedular then switch wifi off then reboot.
