[request, forum] setcpu configuration

Hello, anyone know how to configure setcpu to save the battery while maintaining a smooth flow of the phone?
I saw that we could create "rules": those who did, can you post your configuration.
Thank you

Yes, i've good settings!

These are same settings as teknologist have. This is the man who did the kernel for MCR ROMs. In my eyes he is a god in this things. So I belive him full!

see this and I think should be added here. http://www.pokedev.com/setcpu/

With this configuration, you save the battery?

If yu wanna have the longest battery time, just use all 245/245 Mhz.
But this makes no sense.
I think you wanna have it between battery/speed, isn't it?

obviously! I want my battery will hold at least two days! I will try your setup throughout the weekend and I'll make a return Monday.
thx

Don't hold your breath. Im being serious here. It wont last unless it sits in standby most of the time and then you're still pushing it.
Spend the 25$ extra and get a second battery.

2 DAYS?! Let me know if you are able to accomplish that somehow! I've tried everything; ROMS, Kernels, Juice Defender, SetCPU, anything you can think of and about the best I can get is 15-16 hours with moderate to heavy usage. I think I am actually going to buy a spare battery today.

.. that's not hard to do, 2days... even more.
Just stop all apps to update, stop auto sync, stop background sync...
you will be surprised*

I knocked down my cpu to 500 or so in all conditions, phone still feels responsive.
If you want two days, turn off 3g, turn off sync, turn off brightness. You'll not only get great battery life but a $600 dumbphone to boot!

this is what you need to do...
sleep/standby 245min 245 max cpu governer: powersave
charging 245min 883 max cpu governer: on demand
'normal': 460min 998max cpu governer: conservative
if u find that with normal use the phone isnt as snappy as it used to be, and this bothers u, then change the cpu governer back to on demand for the normal profile.
i've had amazing battery life since i tried these settings.
Also....some apps prevent the phone from sleeping so keep an eye out if ur battery is just literally disappearing!

Setting the max too low on any profile is not a good idea. This can cause tasks to take too long to complete and queues and memory to fill. This can make your phone unstable and arguably increase battery usage due to increased management overheads.
Some overhead above minimum is always preferable. I would consider anything less than 245/576 quite extreme and normally undesirable.

yeah i heard about this but i have never encountered any problems. obviously its different for everyone but i would say try 245/245...if your getting too much drain with the phone on standby then use 245/576 with on demand governor.

To be honest everyone "thinks" you can see a night and say difference just by tweaking the clock's and installing more efficient kernels. You can't and wont.
Those things may save you 5-10% over the course of a day but don't expect miracles. If you look at your battery history information you'll see that the system and any CPU related item can become relatively low doing all the efficiency modifications yet the battery still poops too soon.
Now look at the display. Thats where it's all going and as far as I know there is nothing anyone can do about that on our side. I run with the display back lighting 100% OFF and it still shows at a HUGE portion of my energy use. ~50% and sometimes more.
The day we get more efficient screen technology is the day we will be able to possibly use these things for 2 days on one charge... Either that or more powerful battery technology.

You know guys, I only have 3 scales on the application. Userspace, ondemand, and performance. I also have no idea what Priority means and how high or low to put them for a good profile! What do I do?

Set a default scaling type that suits you, typically On Demand or Uberspace and then set up your profiles. All of your profiles can use the same scaling (mine do).
The set your profile priorities in the order you want them to apply, 100 is the highest priority. For example, you might want the phone to run with less overclock when the battery is low and you want this condition to apply all of the time then you would give it a higher priority than other rules so it always executes. A better example might be a temperature profile. If the phone is hot you want to clock it down and want this to NEVER be overridden by another profile then you would set this to very high (say 99) so it could NOT be substituted by another rule.

SetCPU usage/benefits?

I was thinking about installing SetCPU but I have heard stories of it not working very well on the Captivate. Does anyone use this, and if so what kind of battery life improvement are you seeing? Post config settings too please!

Its working just fine. I have a live background so my battery usage isnt very great so long as the screen is on. I had some trouble with the system being slow to respond every time I turned the screen back on when I had "screen off" profile set to max 200 and min 100. then it dawned on me that it would always just underclock to 100 I set it to max 200 and min 200 when the screen is off and also started using launcher pro and it is no longer sluggish at all.
This has saved me a gratuitous amount of battery life when the phone is idle.
Default profile
Max 1Ghz
Min 800Mhz

Same as default but scales on performance
Battery <50%

Thanks for these, I was looking for a some decent settings. Mine were close to that to start, but I had no idea what I was doing, haha

I had some stability problems with it that I am now fairly certain are related to adjusting the polling frequency in advanced settings. After disabling setting advanced settings on boot, and a reboot, it has not caused the phone to hang once. I am also fairly sure that the phone boots with the conservative governor enabled and min/max frequencies set to 100MHz and 1GHz, even without SetCPU - so the main benefit here is profiles to force lower clocks with screen off, or during overheat or low battery.

CPU throttles itself. Any effects of setCPU is placebo effect

Err if you set the clocks yourself, you can produce a difference depending on what it's catered towards. I'm sure if I set the max clock to 200 (assuming the app works) for all situations there will be a difference.

Does the stock ROM have a perflock like the EVO that we need to disable?
Also, does the stock ROM automatically underclock at times, or???

I've now verified after clearing user data, the stock firmware already sets the conservative governor and allows it the full range of frequencies supported by the CPU. Only benefit from SetCPU should be profiles - reduce max clock when hot or low battery, that sort of thing.

I was going to make a screen off profile of 200mhz, to save battery. Should I bother doing this?
Edit: Nevermind, I'm just going to uninstall it. It's locked up my phone twice already

Default Profile: 800 MHz
Profiles:
Temp > 46 C -- 400 Max 100 Min Conservative
Battery < 40 -- 400 Max 100 Min Conservative
Screen Off -- 400 Max 100 Min Conservative
This now gives my phone life of about 2 days with moderate use (1 hour calls, 1 hour browsing and another 30-45 mins of using apps that need screen on like games, etc)

One thing u got to keep in mind, CPU scales up when woken from low speeds (like when u set for 200 n this takes a second or two). After some R&D i realized 400 MHz when sleeping is optimal with hardly noticeable lag.

well, i have tried playing heavy games like asphalt 5, dungeon hunter, assasin's creed... these all games seemed to work with no lag even at 400 MHz when my battery was less than 40. Most apps I have or used or saw were very comfortable even at 400 MHz. But with multiple apps open, sometimes there was lag, so i set the max at 800 MHz, instead of 1 GHz.
Also, I set my connection to EDGE from 3G. This helped reduce phone from getting heated up with long calls.

I tried using this app myself but uninstalled it after a week. While I'm sure there was some underlying cause, it made my phone never wake up from sleep mode when it turned off.
Honestly thou, I know several android phone owners with s lot of phones That didn't see any real change in their battery life as s result. And based on my experiences, I'd say stay away from it.
Just my 2 cents thou

[Q] Optimal CPU settings

Hello, I tried searching but didn't find a thread about this. Sorry if there is one that I didn't find. I'm playing around with SetCPU and trying to figure out optimal settings. I know its a matter of preference but I wanted to see what everyones opinion is and what they have theirs set as. I have:
CheckROM Revo noteHD v5
Abyss Kernel
On Demand governor set
Max 1500MHz
Min 200MHz
I want a happy medium between battery life and performance.
I set a profile for screen off to min 200 and max 500.
I've been reading mixed reviews as to whether or not lower speeds actually increase battery life. I originally had the min at 50 but increased it to 200.
Another question is what would be a good temperature to set the temp profile to? Not sure when the phone begins to get too hot.
Thanks in advance

I used FM kernel with ondemand with min of 500Mhz and max of 1400Mhz with 2nd core always enabled, didnt notice that much of a battery loss.

go for rocket rom v22 with abbys note 4.2 kernel
set cpu min 50 max 800
on demand (if u want both cores active)
abbysnote (if u want single core running and 2nd to be used only if required otherwise 2nd would be off)
i got normal usage batt backup of 3 days least

Incredicontrol

We finally have root permissions, so i decided to try incredicontrol... anyone has already tried it?
I lowered the max freq up to 640MHz, and lowered the minimum freq up to the minimum (51MHz). The phone remains agile, no lags.
I noticed an improvement of the battery life, and the phone doesn't overheat like before.
The system uses more cores, not just one as with the base frequency.
I verified with the options "show cpu usage" in the hidden menù.
I suggest to use the interactive governor, because other governors don't use the shadow core.
We still cannot undervolt because there isn't a kernel that supports undervolt...
ps sorry for my bad english, but i'm italian

this app is simple, but unfortunaly it crashed for me to often, i use cpu master, set max speed to 1000 and min speed to 51mhz,
i think these tools are not full tegra3 rdy right now

mmm maybe.... maybe we have to wait new versions....... but on mine incredicontrol does not crash

CPU master
My CPU master doesn't (never) crash(ed) when i set max min CPU. Perhaps your app is buggy?

[Q] Which setting (cpu frills) for the energy saving?

hola a todos
which minimal or maximal frequency of scaling cpu is necessary?
(sorry my english is bad)
my setting:
min freq. 384mhz
max freq. 1242mhz
governor ondemand
scheduler noop
ps: no frills cpu is recommended?
thanks

cpu fre unninstaled...because not save battery...
see you

When not playing games i have 0 lags on min 384 max 1024 mhz. Governor Ondemand.I have huge battery saving with this but im on cyanogenmod. Have about 5 hours screen on and 1 day + time.

Faux CPU allows you to setup profile so max frequency can be raised for specific apps, such as games.

my xperia zr: 4hr and 30min screen on, with stock rom..... because im freeze apps and uninstalled bloatware.
tomorrow or later, create new post with full list.
regards n sorry for my poor english.

??
have you already tried the cpus frills on last version .101?

Guys i have been using the ZR from the last 5 days and noticed that the cpu don't sleep most of the time. Whatever util I use it still runs more or keeps itself busy.
Any ideas? Still I am using Stock 4.3 and i have frozen many apps that are been running in the system and removed a few. Fearing that i shouldn't have a bootloop because i am removing a system file.
Anyway, any suggestions to what to do with the cpu using itself unnecessarily? without any of my intervention?
Also noted that it is going to the max most of the time when I connect the USB to PC to charge the phone. That skyrockets itself and the temp rises more than 40C.
