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.

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

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?

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.
Hi fellow androiders......have loaded Set CPU and would like to know what if any is the optimum profile(s) setup for the Captivate.....Thanks
I turn my CPU back to 1 ghz if temp > 50
I also go 600mhz max when the screen is off.
I don't see much need for the rest, but I'm curious to see what others add.
What is the lowest the CPU can go on the Captivate?
Sent from my iPhone with the bigger Gee Bees.
Pretty nice app, although I can't seem to be able to go above 1ghz in cognition 2.3B2... But I have set to.
Temp>60 400mgz (I live in the desert)
Temp>50 800mhz(totally nessicary)
screen off= 100-400
charging= 800-1000
and some other little battery things thrown in.

lowest is 100mhz... would NOT recommend setting MAXCPU on anything to that!!
It will idle at 100, but if it can't clock up, you'll never be able to use it. 400 is functional for call/txt.
I never have heat issues with my Captivate, and I don't do any oc-ing/uv-ing. I personally use:
Screen off: Max 200, Min 100, Scaling Conservative, Priority 100
Charging/Full: Max 100, Min 400, Scaling Performance, Priority 75
Battery<101%: Max 800, Min 100, Scaling Conservative, Priority 50
With Darky's ROM and Speedmod K12N kernel, 800MHz cap gives plenty of performance. 200MHz while the screen is off is just fine for playing music in PowerAMP with headset controls.
hello i am searching for the best setcpu settings for G1 so i will get the hell out of my g1 !! please help and if double post sorry i didn't see the other at related threads
576 max, 528 min
122 122 on sleep
This is the setting that I have been using, the good thing is it has failsafe profile as well to prevent overheating
Profiles are listed according to order (high priority to low)
Main setting 528 max 245 min
Screen off 245 max 122min (245 max to allow background apps to function properly)
temp>38.6 352 man 245 min
Charging 537 max 245 min
Battery<40% 480 max 245 min
u can set your own max speed, but not advised to go beyond 576
245 is set as minimum when awake because that is the original minimum clockspeed of the cpu
remember to check 'set on boot' and 'enable profile' setting
change them to your liking n have fun!
p/s: my setting is based on this http://forum.xda-developers.com/showpost.php?p=6762470&postcount=208

try it out for yourself, set it, and forget about it, and do your normal daily usage, after that you'll notice of the extra juice available

Keep in mind, the best settings may be none at all.
SetCPU does take a few MB of available RAM - a precious commodity on the G1. I've been going without it using Farmatito's kernels - it defaults to 528 and 245, I think. Only drop about 1% an hour on standby.

Good idea! It may be wise to remove the SetCPU to get more available RAM if the battery won't drop fast without SetCPU.
It seems the CPU scaling is not set properly with the kernel that cause the phone runs warm and decrease battery life. Checked with CPU Spy and I noticed it often idles around 1134~1026MHz, instead of all the way down to 384MHz.
What you need:
1. Download any CPU control apps, like AnTuTu CPU Master, No-frills CPU Control, CPU Tuner...etc...
2. ROOT!
3. Set the minimum frequency to 384MHz. Leave all other parameters unchanged.
4. Check Apply on boot.
Now check with CPU Spy again you'll see your CPU idles at 384MHz and your phone is running cooler.
Yeah seems the kernel needs to be tweaked a little. It will most likely be patched by .1
Sent from my Nexus 7 using Tapatalk 2
the phone goes in standby, but the cpu stands over 1000Mhz instead of scaling at the bottom?
Mine already goes down to 384mhz without intervention of any CPU apps. At this very moment my CPU is at 1% and clocked at 384mhz.
I don't think doing this will have any effect on battery life or heat.

Mine aswell. Clocks down to 384 Mhz when doing nothing.
Thermal throttling is NOT supposed to throttle to minimum, its not a rollercoaster. It would lag terribly intermittently. Perhaps the threshold needs to be brought up, but the throttling clocks seems about right. Something else that could be done and help a lot is adjust the voltages.
Edit : sorry I misread your post.

Mine does go down to 384MHz. But my point is the CPU does not go down to 384MHz when it should be.
From CPU Spy it seems like when idling the CPU half time stays on 1134MHz and half time goes down to 384MHz.
After the tweaking the CPU goes down to 384MHz all the time, and does NOT affect smoothness or fluency of the system.

Mine oscillates between 1 and 1.5 Ghz while in use, and goes down to 384 when lightly used or when WifFi is on (Wifi prevents my phone from entering Deep Sleep). The rest of the time, it's in Deep Sleep.
384 is the minimum? Damn, I remember when 384 was the maximum.

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.
