[Q] The perfect SetCpu settings for powersaving

I'm really struggling with battery life at the moment. Has anyone got settings I can use to save on battery life in SetCpu? Profiles etc

+1
I'd like to know too.

I would also like to know =[ my battery dies wayy too fast. I have the darkstone froyo build on my htc hd2 phone energy rom. Any programs or SETcpu settings that will help out?

If your on a rom with preflock disabled then you can underclock.
The only thing you need to change in setcpu really is to make a profile for screen off and set it to 245 (or whatever is the lowest I can't remember) both max and min (leave it on demand, or interactive if your rom has that).
This should give you about 10-15 hours longer battery life

so i wouldnt have to make any other profiles like battery? temperature? stuff like that? should i get rid of my green power and advanced task killer?

No you can keep them (well I don't know what green power is....)
The other profiles are mainly only needed if your OVERCLOCKING, however if your not touching the default max (main profile) then your not overclocking (1ghz).
To save power you UNDERCLOCK which setting a lowered screen off profile would do.
If your slowing the CPU down then the temperature will not rise, so that profile is not needed.
And you don't need to slow the phone down when your using it so none of the others are really needed either.

i think im kinda get what you're saying (sorry im kind of slow) so i had just deleted my other profiles and made a screen off one have it set to max all the way right and min all the way left, on demand, priority 100. Now on the main screen i think i touched it cause i read somewhere for max all the way to the right and min all the way to the left. This is confusing lol

The settings I have for my Desire:
Default:
Conservative 245-998
Profiles:
Screen Off - Priority 100 - Powersave
Charging/Full - Priority 50 - OnDemand 245-1305
Battery < 30 - Priority 0 - PowerSave
Running along side JuiceDefender, battery life is acceptable to me

That totally defeated the purpose of my question and others before me. Our battery lifes sucked without any programs so now we delete it?

I used darkstones froyo for awhile too. Battery drain killed it for me. I had no luck with anything. Changed to a nand build and its much better. Apparently SD builds just use more battery. With the SD froyo I could never stay below 60ma a few times would drop to less than 10ma but just not consistent. I lost about 8% an hour in sleep mode. Give a well designed nand build a go. In sleep I hover AT 4ma. My battery with Moderate use easily last the day, heavy use (multiple calls, emails, and browsing for an hour or two) still does require a recharge

Im using carbon ara theme with pcb just turn data off wen aint using it via toggle and have a profile for sleep in set cpu for min and max of 245 and from full charfe at 7am by 6 pm im still 65%. Thats using fb checkin email playing angrybirds and checking the forum

bad idea as you are actually making your battery work more by doing that.

New to SetCPU!

I know there are quite a few threads on setCPU BUT this is my first time using and i was wondering for my rom, kernel, and phone usage what you guys think is best to save battery but still be snappy when the screen is on.
My phone setup:
2.2 Android
2.15.00.09.01 Baseband
King CFS 10 kernel
Evervolv v0.2.1 rom
pri 1.77_003
PRL 60670
I have the phone on wifi about 90% of the time because some of my reading says it saves battery. I use my phone for browsing facebook and a few forums, send a few hundred texts a day, talk on the phone maybe 10 times a week ( im a college student), regularly on email. NOW with that said how would YOU set up the set cpu for battery life but no lag while operating.

You need to update your PRL ...

I always leave my main profile at 245 mhz min and 998 mhz max (ondemand mode). Then, of course, you'll want a screen off profile, and as far as that goes, I've heard that 128 and 245 draw the same voltage, so I have mine set to 128 min, 245 max (powersave mode). Other than that I just have some low battery profiles and a temp one. I don't really get any lag with this setup, but I've heard some people do. If that's the case, and I'm only talking about lag when first turning on, just up the 245 to 384 or something and I'd make it ondemand.

do i need to check set on boot under the scaling option

No. I would leave it unchecked. This has been known to cause some issues.

what kind of issues are you talking about? i've only heard and practice leaving it off when experimenting with overclocking (since it can put you in a boot loop). once you find a stable overclock speed, you can check it to start on boot so that you don't have to open setcpu every time you reboot if you decide to run it at that speed.
on-demand is a little less laggy (barely noticeable to me) but may consume more juice than conservative.
most kernels will step down to 245 when the screen is off so creating a profile to do that is redundant. you can verify this with the app android system info under the system tab > cpu.
having said that, i don't use setcpu unless i'm benchmarking and want to overclock.
kings #6 bfs kernel is awesome for battery life (default is conservative governor). it's what i use. give it a go when you've gotten a good feel on how kings #10 cfs is working out for you.

Here's what I would hit up..
set it to conservative. Conservative starts your phone at your minimum clock speed and works its way up, as opposed to on demand which starts at the highest and works its way down.
then for advanced i have sampling rate at 50000
Up threshold at 95% <- that's saying that when the workload hits 98%, crank up the processing speed
Down threshold at 70% <- when the load hits 70% turn it down
That stuff right there is agressive as hell, and when I say agressive, i mean...you probably won't ever hit your max frequency unless you are seriously doing some heavy lifting. The settings there are what I use to save up battery, you can get through a day easy with everything on (GPS, Wifi, sync, 3g, the works) and with your current usage, since its similar to mine (except that i also run beejive, skype and twitter at refresh rate of 5min).

Yeah I think you've probably just seen that on some custom kernel pages. They only say not to do that because if you're testing battery life with say...HAVS, it could interfere w/o you realizing it. Set on boot just means you don't have to turn setCPU on everytime you reboot your phone.

just go set a profile on minimal mhz and on powersave mode if kerenal allows if not just use ondemand

My problem with the "Set on Boot" option is if you accidentally fat finger the slider past your stable clock with it checked, you're looking at boot loops and possibly having to restore from a backup to sort it out. SetCPU really needs the "Set on Boot" option grayed out and a "Lock Settings" option that must be checked before "Set on Boot" becomes accessible (unchecking "Lock Settings" would also uncheck "Set on Boot").
Another option would be a user defined field for max stable clock in the advanced settings that would limit the slider on the main tab. Either one should eliminate accidental boot loops.

SetCPU Gingerbread

Is anyone using SetCPU with gingerbread?
I'm using GingerVillain 1.5 but I can't seem to find the right profiles with SetCPU.
Oc'd @ 1,2 Ghz without profiles.
Because when I use the screen off profile, my screen sometimes won't turn on.
Screen off - min 245 max 1200
Can someone help me finding the right profiles?
Share your user experience.

In my experience and many others too, the profiles are not needed. The only profile you should ever need is a temperature profile and that's only if you really have it cranked up.
Having a screen off profile is always bad since switching to another profile doesn't happen instantly - there are polling intervals involved and until the next cycle runs your phone will still be using the screen off profile. That makes the phone slow which causes SetCPU to take longer in switching profiles, bogs down the cpu and it becomes a vicious cycle for a few seconds (sometimes a couple minutes). All the while it's draing your battery because the cpu has to work harder. Even regular profiles eat the battery due to the constant querying of the systems status and processing power used for that - which is the main reason you'll hear people whining about their battery life (some aren't effected as much).
Profiles are just not a good idea except for a temp profile for those that oc to the higher GHz (probably 1.4+).

You could try using cpu tuner instead. Gives you way more options.
CM 7

You have a lot of options with cpu tuner.
What triggers and/or profiles do you use?

My screen on/off has been working fine with CM7 nightlies before and after the RC1. I've been using SetCPU with a normal profile of 1017max/245min and a screen off profile of 365max/245min.
I think your issue is with overclocking. Idk about Gingervillain but as far as CM7 goes lots of people are having issues with the on/off animations and wakelock issues when overclocked over 1ghz. Try using your profiles and clocking at or under 1ghz and see how things change.
Not sure why anyone would really need a higher clock than 1ghz but what do I know. I dont see any slowdowns at 1017mhz and I feel that anything faster than that would lead to heat or battery issues?

Yes, screen off profiles work. But they drain your battery faster than if you have no profiles.

thanks bro, i OC'd to 1017 and there are no issues

I'm not so sure about this. Have you tested this at all? Starting using screen off profiles of 365max/245min have really increased my battery life, especially when my phone sits idle for a decent amount of time. I don't think you could see more battery life by leaving the clock at 1ghz while the screen is off.

Every kernel that I know of out there drops down the clock cycle when the screen times out. The reason not having the screen off profile saves the battery is because SetCPU isn't constantly sending requests about the phones state and then checking that against your profiles to see if it meets the parameters set in them.
Now it could be a bit different for you. You might have a different set up or different apps that make having a screen off profile useful (ones that constantly update or run in some way). You just have to watch your phone for a few days and get an app that keeps track of that stuff so you know which route to take.

This is very true. It is definitely hard to make a blanket statement because no two people have the exact same setup. All I was saying is what I've been doin with the screen off animation and I've been having pretty solid battery numbers.

[Q] Underclock below 300MHz for Defy / Defy+?

I recently have bought a Defy plus.
Stock 2.3.4 ROM used so far with LauncherPro.
Doing OK with battery life so far, but now starting to look at the CPU over/underclock capabilities. Started with Antutu CPU Master and CPUTuner also.
One thing I haven't seen as yet is the ability to underclock clock below the min 300MHz.. or even whether this makes sense. I guess undervolting is the other option, but perhaps someone can guide me here.

use setvsel to oc/uv, thats the easiest and best app imo. although underclocking your phone below 300mhz may cause instability and makes the phone wake up much slower in my experience.
sent from my cm7 defy...

I agree with zakoo2: Going below 300 will not be a good idea and it will most likely not improve your battery life in any significant way:
My Defy is running between 300-600Mhz and right now the LCD screen is the biggest consumer: Changing the (auto-)brightness settings in CM7 will do *much* more to your battery life than going below 300mhz.

What really helps saving battery life: use setvsel and leave the minimum clockspeed at 300MHz, but set a vsel value of about 20 for it, then scroll down and enable "limit to vsel1 while screen is off".

Also, going below 300MHz will probably make the phone sluggish when waking up from sleep like if a call comes.

im just change from 300mhz to 330mhz lowest. 300mhz will make my defy+ lag when got incoming call. im using smartass govenor.

I heard some guy out there got 80 MHz and running, but I'm not sure of it.
As people said, clocks lower then 300 MHz would make your phone run horribly while waking up (i.e., it would take a long time for the screen to turn on when receiving a call, and you would probably miss it most of the times). Setting 300 as VSel1 and limitting to it while screen is off (2nd-init enabled bootmenu has this option, and downloading SetVSel - free at Android Market - will also do the trick if you have a rooted, but stock ROM) will help you save a lot of juice. Using a lightweight launcher (I personally recommend MetroUI or Zeam) also boosts up batt saving. Last, but not least, setting brightness to auto or minimum (using frosted/mat screen protectors will help a lot while using the phone under direct sunlight) also saves loads of charge.
Obviously, using a light ROM (I think Barebones may be a good option, though I think it's not suitable for me, but it's a personal matter) and calibrating your battery in a monthly basis (via manual calibration - you can find how to do so by googling -, wiping batt stats in custom recovery and/or using the batt calibration app included in most ROMs - but also free at AM) also help.

[Q] SetCPU Randomly Rebooting One X?

Hi All,
After being a long time iPhone user i recently purchased htc one x, as a result my android skills are almost non-existent; so please bear with me.
I managed to flash clockworkmod recovery and rooted with SuperSU with no issues.
Purchased setCPU after reading the reviews and enabled. However the phone would reboot randomly a few times a day. Ususally when the screen was off.
After disabling setCPU there was no rebooting issue.
Has anyone got this app to work on the OneX, and if so which settings did you use?
Also has it been confirmed to work with all 4 cores?
FYI I had the following profiles setup.
Screen Off
Freq:640Mhz-51Mhz
Gov: conservative
Temp > 44.5
Freq:880Mhz-51Mhz
Gov: conservative
Battery < 30%
Freq:1000Mhz-51Mhz
Gov: powersave
Charging Any
Freq:1500Mhz-51Mhz
Gov: ondemand
Please note these profiles are based on no evidence, just on what I estimated to be about right...
Cheers

I did not start using SetCPU on my phone yet because it's not rooted, but first I would check if SetCPU doesn't require some kernel support? and if that's implemented in the custom ROM you're using? (if it's needed, I'm not sure).
Or maybe SetCPU needs an update to properly support our phones?
That Temp > 44.5 Profile, wouldn't that interfere with gaming? I have never used Temp profiles before (is it really needed?), only the other ones, like battery and screen-off and charging.

my one x has unlocked bootloader, recovery and root. I was running into some serious intermittent lagging issues, the phone in any app would just stall for 5+ seconds. after hours restoring after failure , it came down to the problem that using ANY cpu controll app, messed my phone up... BADLY! it seems at the moment (im assuming) apps like setcpu and cpu master are not quad core ready...

thanks for the responses guys.
I guess ill just wait until one of the devs can confirm this as working...

The reason is simple. We don't have rooted kernels yet. Until then stay away from messing with CPU speeds or under volting. Etc.

DO NOT mess with your CPU speeds yet. Undervoltage is causing reboots!

the software is not up to the hardware capability, i dont think the cpu control apps can handle quad core yet. and there is a lot of apps (esp. games) that lag a lot, and amazingly the cores are too lazy to work... im hoping for a better kernel that will address this issues.

If you want to at least see what's going on with the cores, I can confirm that Tablet CPU Usage Monitor works on HTC One X
It shows 2 icons in notification bar, each icon showing usage of 2 cores. Not sure how accurate it is, but so far had no problems with it and it seems to be reporting correctly. Developer is working on single icon with all 4cores in it, to save space.

I had the same problem, but if you delete your profiles you won't get reboots.
I'm just running default profile Max: 1500, Min: 760 Ondemand gov. and it has been a straight line for 6 hours when I was sleeping and no reboots.

I was having that problem too... In my opinion, I don't think that the phone can handle the Conservative governor setting. I set my governor to Interactive (On Demand works too)
Right now, I have my profile set to 1000mhz max and 475mhz min, with screen off profiles set to 475mhz max and min. I have not had any problems with the phone rebooting at all since setting those freqs. (And I don't want to quite go any lower yet). And I have it Set on Boot.

im now using rooted HTC One X(HOX) and installed RD-MIUI ROM quite sometimes. my kernel is still in stock. Im using setcpu and NO random reboot happen like what you have said. Yet, i am still confuse whether setcpu is good for my phone. based on my review, in the leading rom developer thread they not mention setcpu for their choice. they play alot with kernels to govern their hox cpu-s. could anyone do some comment.
