Hi,
I have detected the reason why the battery at JVK is always so quickly. The Android OS syndrome.
It is the CPU running at 1000Mhz permanently. Even if the phone is in standby. Otherwise, switch the MHz number in stand down even more. What can you do?
Cpu doesnt always be on 1ghz.You can see in what frequency the phone is using setcpu.
The CPU is not running at 1000MHz constantly. And if you are afraid that it is, do the following:
1. Download SetCPU from the Market.
2. Enable profiles, and set following profiles:
- Charging: min 1000, max 1000;
- Screen Off: min 100, max 200;
- Normal: min 100, max 1000.
This will also increase your battery life!

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
scaling Conservative
Charging/full profile
Same as default but scales on performance
Battery <50%
Max 800Mhz
Min 400Mhz

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

Which is the best setting to keep your setcpu for day to day use? Userspace? Performance? Conservative? On demand? Ineractive?
On demand probably.
Anybody else any suggestions
I use interactive... and screen off interactive..
Sent using SkyRadier 3.2 RC3 Incredible ROM with King Kernel #5 and the 2.15 Radio.
I kept stock myself, Min 245 Max 998 I believe, but here's a thread for this( n1 setcpu)

I have my set CPU to on demand.
But you should also enable profiles...
Such as "screen off" set to 245 for max and min that way when you lock the screen your saving the most power. Also for my own sake I set it for "battery<20% to be around 600 max and of course 245 min, just in case I'm low on power and need to conserve for some phone calls.
On a Samsung Galaxy S with MIUI Stable 2.11.26.
What are the best settings, profiles, ect. for saving battery? Also please label the specifics like max/min, scaling, and your advanced settings.
Thank you...
For Saving Battery keep both max and min at 800000 and scaling should be on conservative....
Worked for me
..
I'm on Onecosmic's ICS Port RC3 with Platypus Kernel. It runs fine at 1460 Mhz and CPU Spy tells me 38% 1460 Mhz, 42% 800 Mhz and 18% Deep Sleep. Temperature is between 33 and 38°C. Battery life is just fine, one day, sometimes two (depends on usage surely).
My question is:
46% overclocking seems to be much for me, but as temperature stays fine, do you think i risk a sooner death of my cpu? would you change to 1.3 or 1.2 GHz?
If the CPU temperature is fine then therez no need to take any tension.. ur cpu will work fine..

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.
Hi
My s5 default frequency CPU are 300 Min And 2400 max.
I have root. stock rom And kernel. I have Read about clocking And if i increase CPU sped in its Min values The CPU should be more reactive. (i have stock kernel for mantain knox To 0x0 And i don.'t need a overclock up 2400 because 2400 is enought i think..) So, if i have 300 Min And 2400 max which Min value Can i set without problems? 400?652?728?or 883?
Now i have 883.. It' ok for CPU or i should have problems ? I Can set more than 883?if yes what CPU Min frequency could i set?
I have set when The Phone is charging or screen is off or calling The CPU turns To normal values (300 Min 2400 max).
The governor i use is stock interactive scheduler row.
I dov'è care about battery. If The change drop fastly is Not a problem for me. I want The Phone more reactive And responsi possible without problems on the CPU ecc..
Shouldn't have any problems, you might experience a bit more battery drain, that's about it. Sometimes when my screen is on, my phone automatically adjusts to 1190 as min, so I don't think you need to do anything.
Stock kernel, rooted
883 is too Hight or i Can set more? Like 960 or 1036 or 1190?i think more that 1190 is excessive.
In My experience when you open setcpu And do Nothing normally The CPU is 300.when you simply touch The screen it increase To 1190 so The 1190 i think is the minimal value of CPU when you use The Phone for operations. So maybe i think i could be ok if i set 1190.
