Battery

Hey fellas.
I just want to know which is the best settings for governer and i/o scheduler so that i get more battery life.
Im using Ussr v5 and i' ve set max frequency 624MHz and min 312MHz.

use gov:conservative i/o sched:deadline
this wud save ur batteryy..

Droidwall is a much better app than juice defender, it saves a lot more juice than juice defender does and that too without any RAM and battery consumption.
Best Power Saving Governors
Best for Screen ON: Ondemand
Best Screen ON + performance: SmartassV2
- Good choice if you need a performance governor with some power saving
What about when my Screen is OFF?
Best Governor for Screen OFF
Without Deep Idle: Same as Screen ON > Ondemand
With Deep Idle: Any governor

U need root access for droid wall.. And juice defender is fine for un rooted devices.. Was talking about an unrooted phoneView attachment 1320249

The OPs phone was rooted..btw juice defender might save some battery but it takes a lot more since it runs background all the time, monitors every system function (wifi disabling per app settings) which needs more juice than normal, it depends whether it saves battery or not, for an aggressive user who shifts to wifi, 2g very frequently, it definitely saves, but for those who use 2g/wifi rarely or not actively, it wont matter much on the battery

Its because galaxy y stock kernel does not support droidwall.
Use a custom kernel which supports droidwall.

Does merruk kernel supports it?

Hmm.. I don't use merruk kernel, so m not sure. I just checked its features which says "NETFILTER Compatibility with DROIDWAL." so thought it supports.
Though it also have a to do list listing "DROIDWALL App Fully Working"

Smartassv2 and vr

from my experience governor give very small impact on battery live. if your phone mostly in sleep, like mine, i find best governor is performance. performance does not save power but it's maximize suspend (aka deep sleep). faster cpu working, faster it's job done, faster it's go to sleep. for moderate usage like browsing, any governor that design to work with android phone will work. the different is not too much. for heavy work, none governor can save your power.
for i/o scheduler, it does not have any impact to your battery.

best cpu settings for jellyblastv3

i have installed jellyblast v3 in my phone i need to know which is best cpu govner setting i tried conservative+sio..it lags when i type in keyword n also feel the lag through headset can anyone suggest me plzz..its so laggy i cant use my phone now..
Sent from my GT-S5360 using Tapatalk 2

If u want to save batttery use conservative + sio
for performance use Performance + cfq
and for balance use activecats + sio

thanx bro..can we use battery saver with this rom to save more battery..because the battery drains within 4hrs if i use internet continuously..

that's normal..
And battery saver will make your battery drain faster than before.
Continuous data exchange drains your battery faster, specially when you are using 3g.

[Discussion] Cpu Profiles

Hello guys,
I'm here to ask for all of your opinions about the cpu Profiles, frequencies and governor.
For screen on I'm currently using 1200mHz on performance, I would like to know if it would save more battery by using on demand governor.
Some months ago I had a discussion with few xda members about this subject. But that was on aurora v4. Now I'm currently on v5 u17. Let me know your opinion. Thanks
Sent from my U8800 using xda app-developers app

To be honest, I've never experienced any benefits of setting cpu profiles for screen on, screen off etc. Your phone will work much more smoothly if you stick as close to the defaults as possible.
I don't use profiles. My min is 245 and max 1200, using on demand governor.
For a while I experimented with profiles, and had bad lag when unlocking the phone, and terrible battery use when screen on.
Independent of profiles, your governor will put your phone into deep sleep when the screen is off anyway.
Do a search for "race to idle" this explains in more detail the benefits of using ondemand as opposed to other governors in terms of battery use etc.
IMHO, Android as a platform would be far better served if people stuck close to the default settings and cpu profiles. Most of the time, any negligible benefits are just placebo.

So according to the race to idle running with performance governor saves battery
Sent from my U8800 using xda app-developers app

In theory yes, but if your cpu is always running at max frequency, ie even when doing nothing, then no.
I have done tests, and my battery always lasts longer using ondemand as opposed to performance, or other governors.

Use interactive/bfq that's the best in my opinion

[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.

With that combination my phone is slow like hell..have you tried those that i wrote.

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
