SetCPU

Hi all,
I've set some profiles in SetCPU but haven't noticed too much in battery life savings. I was wondering what others who are using CM 6.1 have been doing/would recommend. Should I get rid of the profiles and just have it set to on demand? Do I really need it at all with CM?
Many thanks!

How high are you overclocking?
What's your usage?
What's are your profiles?

Overclocking to 1401 on demand
I use power amp with scrobbing to last fm for probably an hour or two when not charging, while playing games that aren't to elaborate (boring stuff like sudoko) during my commute to/from work, which is probably my heaviest usage. I also do the same music set up while at work but I'm plugged in most of the time for that and volume is way down. Calls range from 30 min to an hour a day. Some intermittent web and video streaming while at home and on wifi. Typically only on wifi when at home, only when I need heavy data. Data sync is turned off when I'm not charging unless I want to sync.
I have profiles of 368/245 while sleeping, 75 priority; 738/245 when temp is 40.5 C, 60 Priority, 1401/245 when plugged and fully charged, 50; 368/245 when battery less than 10, 60; 806/245 when battery less than 40, 50 priority.
I'm thinking the fully charged one is probably redundant. Should I raise the priority on some of them?

I always set temp as the highest priority however i OC a lot higher then you. What oc kernel are you useing? This makes a huge difference some have a lot more steps which allow better power use. Pershoot is the most efficient imo right now.

I think I'm just using the cyogen mod kernel...but I'm new at this so I am a little clueless on that part. I did set higher priority on the temp and the screen off, got rid of the charging profile. I'm at 13% battery after about 15 hours, which isn't horrible but not the 30 hours some folks have been posting.
Sent from my HTC Vision using XDA App

had to dig back to find a good thread to post this on....
so I'm really leaning toward deciding that setcpu profiles do more harm than good in terms of battery. I had profiles set for temp, screen off, charging, battery below 30, and battery below 10. its pretty clear to me now that it wasn't helping my battery. and the only time I even had it overclocked was while charging.
next I'm going to just enable only a screen off profile, and see if having setcpu monitor for less profiles makes a difference. i'm not going to overclock at all. we'll see what happens.
btw I've had a rooted android phone since the G1 so its not like I don't have experience with setcpu. seems that setcpu affects different phones in different ways. so I'm still figuring out how it is on the G2.
anyone have any thoughts on this?

The screen off profile does not work.
Just use the phone out of the box and charge when its empty

really? I hadn't heard that. is this confirmed?
though, it never seemed to make all that much sense anyway, as I wouldn'y think there would be any reason for the cpu not to remain at a low freq with the screen off

The screen off profile works for me. I just set to "ondemand". Lately I've been using "cpu tuner" instead and have noticed better battery life then with set cpu. Plus with cpu tuner you get more profile options.

To be honest, not sure if its the case for you but profiles was the cause of my battery life drain. I took off all profiles and only kept screen off. Even since I did that I get about 24 hours + of battery.

I had a similar experience. The more profiles I had enabled, the faster my battery would drain.
I am using the same setup now and have great battery life. Even with heavy usage I can make it through the entire day without needing a charge.
Running On Demand 1209/245 and screen off 245/245.

Haha this was an old thread. I'm now on CM7 nightlies and would say that in my experience I've had the best battery life running no profiles whatsoever in setcpu. I only overclock to 1017 and it's been pretty snappy still. My experience in going higher than this on CM7 has lead to issues with wake, temperature and battery drain. I personally Have no need for more than 1017.

agreed. this setcpu stuff did not help at my device. nor did it work reliant.
i am managing 1day with heavy use and a full weekend with moderate use without any "tuning".
that is enough for me.

I used setcpu for awhile, but I have been much happier using cpu tuner and "power control".
My battery life is increased by 12 to 24hrs. The key for me is really using power control to manage the screen brightness and under clocking rather than overclocking. The only time I found overclocking usedful was when playing fifa10.
Good luck

Cm7 with setcpu??

Does setpcu really work? With making battery better. I have it set with profiles just not sure if its really helping or making it worse.
Sent from my PC36100 using XDA Premium App

I dont think it is really needed with the CPU settings in CM7 now. Does the same thing for the most part im guessing?

you can do baisic clock scaling from within cm7 settings. as for profiles, if you have a custom kernel and run smartass (on tiamat) or savagedzen (on savaged-zen) governers, you shouldn't need it. those governers do basically the same thing, just smarter.

I was wondering the same thing. On sense roms with setcpu I could easily go a whole day and still have 50% battery left. With cm7 I can only go about 14 hours before its completely dead. The odd thing, I have a profile in setcpu to lower the speed to 245 (the min) below 50%. On sense, I can totally notice it slow down, and can totally notice the battery draining much slower below 50. With cm7, I don't notice any slow down and the battery will actually drop quicker below 50, much quicker than if the battery is above 50. I am using whatever kernal cm7 came with

Try using Tiamat or SavagedZen. I get great battery life on both. You would definitely benefit more from an SBC kernel, but you will still get better battery life with the non-sbc builds of those kernels as well. Which you choose is up to you. Despite a bad name, most users have no problem with SBC kernels. However, the risk is still there. I'll take my battery possibly pooping out early for the extra hours I get out of SBC.
Once you've flashed whatever kernel you want to use, set the governor to smartass (or SavagedZen, if that's what you're using).

Undervolting

I thought an Undervolting thread would be good for me and I'm sure it will help others. Messed with it a little bit on my Inc but haven't on this phone yet.
How much do you undervolt by?
How much better is the battery life?
Any kernels that work better with undervolting in your opinion?

Well, it's not really needed.
I think most kernels already undervolt themselves to the possible max.
I know Franco has something called Smartflex, which takes in a bunch of calculations and undervolts it at the most optimal level (I think) and undervolting manually doesn't give any more real world battery savings compared to it.
But either way, I'd recommend Franco kernel for some of the best battery life.

Straight 175 seems to be safe for most people. I can undervolt lower. I can UV much lower but then I get a reboot at least once a week. The nexus is so efficient at many things uv'ing helps but doesn't impact usage that much. Honestly I don't think you get but about 30 minutes tops extra screen time and I'm being very generous. Uv'does help keep temps down and helps longevity of phone life.

Undervolting shouldn't be relied on for better battery life. It is such a minuscule amount of electricity change. The only thing undervolting should be used for is stability in OC.

underclocking the CPU..

Does anyone know If underclocking the CPU actually save battery life?

It would technically save an incy teency bit but I doubt you will really notice a difference given the small window of safe underclocking. When I tried it my phone ran like crap but what do I know. The way I figured it was the phone was optimized at 1.2ghz. It's like putting 87 octane gas in a high end sports car. Some people swear by it though. Just try it and see if it works for you.

It can but if it's not by much I would doubt you would notice a difference..

Very true. I would just slightly under volt it then under clock it. Like 25 to 50 mV under. Any less than that and you can run into issues. Tagraz has an OC/UC module within the app.
Sent from my SPH-D710 using xda app-developers app

I like to underclock but noticed that if I underclock + undervolt + use any tweaks my battery drains faster... I've been experimenting with different mods and I know on my phone if I just underclock + under volt I get no issues.. if I run just the tweaks ( kob's or td's ) without underclockin and undervolting everything is OK... so trying to see which one is better on battery + performance...
Sent from my SPH-D710 using XDA Premium App

It's been my experience on gb that under clocking from 1200 to 800 vastly improves battery life. It's possible it's placebo, as I've done no specific testing, but the battery life does appear substantially better. Oh and that is with no undervolting

Juice Defender - Should I keep using it?

So over in a Development thread I mentioned that I use Juice Defender Ultimate still, I got some heat for it because it's old.
What's new that I should be using instead? Running CM10 11/30 Nightly that I v6 Supercharged (Die-Hard, so I don't think Tasker will work).
I don't need anything to sync or notify me when it's in my pocket, just calls/texts via radio. I also already use CPU Sleeper and it's locked in memory via v6 bulletproof.
My goal is to make the most out of my battery.

not sure exactly. i used to use green power battery. these data killing apps used to work miracles on gb and froyo. but nowadays i think the main battery killers are the hefty processors. i now focus on kernels and governors and whatnot to save battery. i think killing data will help if it stays off most frequently. when you have the settings to turn on data as soon as the screen turns on, the device is toggling data and constantly searching for signal, maybe even killing more battery than saving.. idk thats just my opinion. and on the other hand.. if your not really using your phone so much i think it would save more in the long run. i would just test it yourself and see what works

Only thing that will improve the battery is a new phone .
I've tried everything. The best result has been ditching AOSP and going back to TW. It might not be fancy schmancy, but it functions and has marginally better battery life (at least in my experience).
Good luck on your quest. I'll probably keep my eye on this thread to see if there are any new suggestions (but not very optimistic).

I unistalled JD and set a CPU profile to reduce clock speed on lock, testing for wakelocks now as well.
Anyone know best governor/scheduler combo for battery on CM10 while still keeping it buttery? Im using OnDemand/Deadline for a few minutes and it has not dropped yet.

Sorry but no one can say for sure whats a rock solid combo. I suggest you try them all like I have to see what works best for you. After trying everything I came back to Ondemand and felt it gave me the best results but thats me.
Good app to try is Llama and its free and does all JD stuff and more

to add, regardless of what kernel i use sometimes the processor will climb to unnecessarily high frequencies when the screen is off. to tame it a little more use setcpu and enable profiles. my profile, when the screen is off, is min 384 max 540 and conservative/noop. then when the screen wakes, interactive/noop 384/1512. but im sure most of you already know this. cpu sleeper will do the trick too. beware of wake lag

I'm using the same Anket battery. I followed everyone's advice, ditched JD and made a SetCPU profile.
I think it was Google Music draining my battery so bad. It's absolutely amazing now.

I no longer use Juice Defender and, for me and my set up, JD did not have noticeable impact.
Nor did more complex strategies using Llama.
The ROMs, governors, CPU settings, and tweaks seem to be where it's at.

I have found that to be the case with every such app I've tried. The best results I've always had have come from removing apps that I don't need or use. I can get thru a full 8 hr shift, so I'm happy.
