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.
Sent from my HTC Vision using XDA App

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

[Q] Terrible battery life on Zedomax.v3

Just updated to the Zedomax v3 kernel and its been great but last night i unplugged my phone at 99% and 5-6 hours later it was at 49% and I also was using power saver under clocked at 800mhz the whole night.
Why is battery life so bad? should i find a new kernel or delete power saver and cpu master?
Also my battery usage says "Android system" is using 35% and display 22%
Usually is higher than everything...?

You need to recalibrate your battery after installing a new ROM. There are apps on the market for this.

If you want to find out what is causing your issue.. download CPU spy and watch dog. Run them on s full battery cycle and check.
CPU spy tells you if your processor is staying in sleep mode and wd tells you what apps/processes are polling CPU for usage

Suggestions on a better / more current kernal?
Have almost the same scenario as OP... was at around 75% at bedtime (with Juice Defender running, and phone in Airplane mode). I usually lose maybe a few points of battery life, but I went from ~75% to 18%. Ouch. Can't go more than 1/2 a day without having to recharge. Ouch. P
lus, phone won't stay shut down. If I power off/shut down, it reboots itself and comes back on after a few minutes. Ouch.
Thanks in advance.

Any ways for ultimate battery life?

I strive on my battery. Using cm7, I make sure everything is toned down and my interface is set at night mode. I was thinking, since I really never need nights on my keyboard, how much more battery would I save by them completely disabled!? They stay off when my battery warns me, so surely their should be a way to rid them all together.
Sent from my SPH-D700 using XDA App

My god how can you stand night-mode colors all the time? There isn't any functionality for changing the keyboard backlight timer in CM7, it will typically stay on as long as the screen stays on. All in all I don't think it will make a huge difference on your battery since it needs the screen to be on for it to be on and the screen uses way more battery. I doubt you would see any major increases in you battery life anyways, considering you're pretty anemic on your battery as it is 0_0

Just having a second battery is a life saver for me. I bought the spare from sprint -it come with a charging case and a wall plug. I just swap out my battery when it gets down to like 30% and then put the low one on the charger.

Ultimate Battery life solution (one of many)
here is what i did. I invested in the donate setcpu app on the market. Of course you need to be rooted in order to take advantage of this.
Make a profile for "Screen Off" and underclock your processor to max = 200 and min = 100, and set the priority high. That way, when you are sleeping or not using your phone, while your screen is off, ur processor has absoutely no reason to work hard, and therefore will drain your battery VERY little.
Try it, I tested how it works, and had a 100% battery life when i went to sleep at 11pm, unplugged my phone and turned off my screen, and when i woke up at 7am still had 100% battery life.
oh, I'm also on CM7 as well, i'm sure that's helping too. haha

I do the same on my tw rom and I go to sleep at 100% and wake up at 100%... if I go to sleep at 80% I wake up with it still at 80%... underclocking the processor while not in use works very well to save battery...

When I try this, I'm not able to turn on the screen again after I shut it off. Apparently the frequencies are too low to process the screen turning on? I have to pull the battery, restart, and then turn off the profile before the screen shuts off again.

Instead of using 100-200 use 200-400 for the screen off profile and it should work better...

Juice defender works the best,what really kills the battery is screen brightness and 3g/wifi/4g data syncing in background for apps that require data.Use juice defender and set profile to extreme,when phone is on standby mode it will turn off radio until you wake the phone back up

Phone feeling hot

Hey guys, I had my phone for no more than an hour. Rooted and flashed cm10. Phone seems to get warm like 100 degrees f. And that's not using data or WiFi.
I had stock on for a little and noticed the same thing, is my phone jacked or is this normal? I have warranty so if none of you guys experience this I'll take it in. I just don't think it's too healthy for the device...

My phone gets pretty hot sometimes too, but only during heavy usage and multitasking. If you're finding that it's heating up when you're just browsing the web or installing apps, try using another kernel. I recommend Lean Kernel with CM10

My s2 barely gets hot :/ and thats with no back cover on just a case. but the battery temps are much lower as well on the S2. usually around upper 70s to lower 80s degrees farenheit under normal load.

yeah
my phone does the same it sometimes does the same it gets hot on the bottom back part

Personally I believe it can be rom/kernel related too. Usually it doesn't get really warm for me except under load. But with the latest leak, if im using it at all, it just stays warm. When I was first using it this morn it actually got pretty hot and when charging got even hotter. I let it cool and hasn't been that hot since.

Mine use to get a lil warm too under heavy usage,until i flashed Faux kernel(<<THIS KERNEL SUPPORT UNDERVOLTING) on sonic Gs3 rom & then i used system tuner to undervolt cpu further(yes undervolt not underclock) although i am running at default clock speed with conservative & cfq settings.Since then my phone runs pretty cool even on heavy usage.I heard the default voltage are sometimes higher than what is needed which may increase phone temperature faster,My battery life is even better now than it already was on Gs3 rom, KEEP IN MIND YOU MUST RUN A CPU STRESSED TEST IN THE SET CPU APP WHEN YOU CHANGE YOUR PHONE VOLTAGE SETTING TO MAKE SURE THERE IS NO ERROR,RANDOM REBOOTS,BOOT LOOP,LAG OR JUST A LIL SLUGGISHNESS BECAUSE YOU UNDERVOLT TOO LOW & KEEP IN MIND NOT ALL CHIPS ARE CREATED EQUAL,So my settings may only be stable of my phone,you may have to take that risk & experiment around.
I attached screenshots of my personal undervolt in system tuner & also a screenshot of default voltage of I9300 variant but i figure.
check the option to use settings on boot in System tuner or you will have to keep setting it on each reboot

Well in my life of hacking phones, under/overvolting seriously reduces life of the CPU.. i dont quite feel comfortable undervolting my brand new galaxy s3. lol. Unless someone can provide scientific evidence to undervolting not causeing long term harm to my CPU.

No reason to undervolt or overclock this hardware. Overclocking became irrelevant when dual cores came out. Undervolting was never relevant. People do it because they like to play around with their hardware, which I understand, though I've always been more interested in software myself.

What are you doing when the phone gets warm?

Mine seems to get hot as the battery gets low (not even on the charger).

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).

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
