Will using setcpu on i9505 will help to improve battery life - Galaxy S 4 Q&A, Help & Troubleshooting

Will using setcpu on i9505 will help to improve the battery life. If yes what frequencies should I set for screen off and screen on.

Yes it can if you under clock.
Try a few and see what's best for you, every phone is different.

Yes as mentioned above. Just under clock and remember to under volt as well.
Alternatively without root and stock, just use power saving mode

SetCPU

I need a setting for my Mytouch 4G with the best battery life, can anyone help me out here?! Thanks in advance plus i can't go lower then 245MHz cause the phone obviously starts freezing....
Not all phones are the same..my best battery life is on fauxs latest gingerbread kernel..using the smartass governor

baller1 alot of things depends as it's not single factor. First the biggest battery consumption on our device comes from the screen so change the blacklight to lowest possible. The second is service/process which runs this would actually depend user to user and based on that your own SetCPU settings. If you have alot of service you never use then disable it on startup and from restarting. Also cut down on media intensive stuffs like widget and live wallpaper or other elements that's always updating. The last one is network bases which would depend on the overall network quality and type of service your connected to in this case find the best radio that works for you first and then depending on your setup push data on given interval. If you stay connected you use more power.
Find a nice rom for example CM7NB and use cfs-lv kernel from faux and let the gov in setcpu be smartass and scale the max/min frequency be 245mhz-768mhz and you can run it with no problem. If you need more power for something then just add next one in setcpu. Also you may want to setup a profile for idle/screen-off mode and set it to ondemand 245-368mhz.

I'm on RoyalGinger 2.0 with the latest kernel that faux had for stock voltage.

you can set a profiles up that change how much power u want, you can make 1 when you shut the screen off and its in stand by and another 1 when you turn the screen on...i do that and it helps alot.
Pm me and ill send you my profiles I use, you'll just have to open setcpu and import them

[Q] Effective CPU Settings for Battery Saving

Hello guys,
I just want to ask some cpu settings that will increase battery life,
Im contented in my tweaks , customizations but my problem only is the battery llife,,
hope you guys can help me
Thank you very much
Use battery saver pro. Adjust the battery saver meter acc. to ur wish, but remember that battery saving is directly proportional to lagging.
The higher the battery saver level, the more laggy the phone will be. Its ur choice...

Remember this will underclock your device. So dont try to run heavy games with these settings (they may lag). Alternately be an advanced user of Tasker, and you can save a lot of battery.
Hit thanks if you think this was informative.

use ondemand and noop..
i already make some reseach 2 day ago on google..
this combination is the best for battery life without decreasing in perfomance..

[Q] Setting CPU using governor for battery saving

I have been using SmartassH3.
What is a good governor that can potentially save battery life?
I like to have it so when the screen is off it is using the least battery as possible.
When it is on I'm not draining battery (like if I'm only using facebook for example) it shouldn't go to the max setting.
Here are my setting
162MHz and 1998MHz
Kernal 3.4.49 AGAT Gs3 v0.3.3+ on MF9
Thanks for the input
As a new s4 owner im wondering thr same thing.

[DISCUSSION]Governors and Schelduers

Okay,so i made this thread so that development thread become less spammed with your questions.
Please,share your opinions here and ask questions,someone will answer you,and share your screenshots of battery life.
I personally use PegasusQ+VR,it gives great performance and good battery life.
My second choice would be Abyssplug+SIO,especcialy for the hotplug feature.
(In case you dont know what Hotplug is,its the feature that turns off the second core when your phone is not in use.)
I cant decide wich is better,tommorow ill test Hotplug+sio,and ill post screenshots of both tommorow.
Please,ask any questions here,dont spam Benz's threads.
Thank you

OnDemand + CFQ (Like in stock ROM) the only way that don´t dry my battery.

Hi, can you tell me the best combination of governors to use. I'm using latest cm
10.1 maclaw build with hotplug and noop, but i think CPU its not sleeping cause i loose about 5% battery in 2hours withought using my fone at all. Thanks
Sent from my GT-I8190 using xda app-developers app ?
Hotplug governor is indeed a joke, at least in Maclaw's CM (not surprised). There is no way to set it up for low battery drain /and/ reasonably smooth functionality. Right now I am using Ondemand + CFQ while playing with the powersave bias and up threshold parameters. The only thing I wish I had from Maclaw/Benz's kernel is the vr/sio schedulers.
You have VR and sio schelduer in Benz's kernel,and Abyssplug governor with real hotpulg feature,when you dont use the phone cpu shuts down one core and the remaining core runs on 200Mhz and 1% usage.
Sent from my GT-I8190 using XDA Premium 4 mobile app
I would gladly use that kernel if it didn't have the dirty flickering fix. And if it didn't require CM10.1 reboot edition.
Also, when I was on CM i ran a logcat with hotplug activated. The second core would often reactivate even if the phone wasn't doing anything, with the screen turned off, then soon turn off and after a few seconds repeat the process. Maybe this phone really needs the core.
What flicketing fix? I got no flickering on the latest Maclaws cm and benzs kernel..and it shuts down the core,you can see with system monitor when your screen is on..dunno for screen off,but i get like 1% drained for a hour with screen off
Sent from my GT-I8190 using XDA Premium 4 mobile app
The 63 fps refresh rate, which "fixes" the UI flickering.
And yes, I saw the second core turning off myself. However, I am not sure if it keeps being off enough time.
Well in maclaws rom i dont have flickering,but in olivers i had. I dont know,i got decent battery life. Not good as stock,but its ok

Pegasusq said to have hotplugging but doesnt seem to work with screen on
Based on what I read, my best guess would be Abyssplug. I'll run some tests and will post my results.

Yes, it only turn off one core when the screen off. I'm testing pegasusq + sio
For the next days, I'll be on abyssplug + sio.

And what exactly is so wrong with 63 fps refresh rate? Will your screen fry because of it? No it won't because it can't. Will your phone explode while being used? No it won't because it can't. What's the issue here then? Tell me.

Have you considered the battery drain implications? The battery is weak enough as it is, a higher than normal refresh rate only wastes more GPU power thus more battery.

setting the Lowest Maximum CPU Freq

hello guys.
i just want to ask this very simple question, what MAX lowest freq i set on the G2? stock at 2.3ghz. can i set it at 1.5ghz? will it battery life?
thanks
Yes you can adjust cpu but you should have root. If you have root then use setcpu
Sent from my GT-I9001 using xda app-developers app
thanks man! yes i have root, and i already set my Freq at 1.7ghz. so, will it somehow increase battery life? or battery will be the same?
thanks
Not that much if you do a lot yes but if you use it moderately it will be useless

Create different profiles in setcpu . I had made a profile in which when i yurn off the screen the cpu comes to 252mhz(maximum) which saves battery
