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

What Rom/kernel are you on? Voltage Control might be the better option.

On leaky gingerbread eeo3, don't know what kernel but kernel version is 2.6.35.7, firmware is 2.3.3...

The lower the maximum speed you can tolerate will give you the max battery life. A lot of people keep 800 Mhz as max for that reason.

If you want a good mix between battery and performance, I recommend keeping your maximum clock at 1000Mhz (default) and lowering your minimum clock to 100Mhz (default should be 200Mhz) if your phone will allow it.

Yeah, just make sure you have journaling on if you are going to try 100 Mhz. A lot of phones get the sleep of death from that. Mine is one of those. Then you will have to pull the battery and adjust your settings to 200 Mhz minimum on SetCPU.

Or....You could not use 100mhz at all!
It uses the same voltage as 200mhz. And by increasing the amount frequencies scaled makes the phone slower.
800mhz max, 200mhz min. 800mhz is volted -75 over 1ghz. Which should increase battery life.

Awsome stuff guys. Thanks for all the great info and to all that reply... Thanks again

I'd quote him but I'm on my phone. Rodderik has stated that all the frequencies use the same internal voltage except for 100mhz, which uses a slightly less internal voltage. What we're adjusting and seeing read in voltage control is the arm voltage, or the processor voltage at each frequencies. I'm not sure the exact difference, but there is a slight drop in voltage at 100mhz compared to the other frequencies? A battery saving difference? Who knows

GN and Setcpu, powersaving.

As far as power saving goes, we all know dark wallpapers, small data usage and brightness can drastically reduce power consumption. CPU is also a large part of power usage especially the GN's dual core. I haven't messed with SetCPU since my nexus one. What might be some of the SetCPU profiles you might be using? And some of the other power saving techniques?
So far I just have a flat black wallpaper, auto-brightness, and a setCPU profile of the lowest MHz when screen off, although I can't tell if the profile is making a difference.

I have screen off at 350/700 because 700mhz only costs me an extra 100mv with my undervolts. And battery <20% @ 350/700 Also but my battery life is so good i havent made it to <20% yet.

You need a kernel such as this
I'm currently using the UV only kernel as I dont find an overclock is necessary on the Gnex.
Basically, the stock kernels on this phone (like every other phone) don't support voltage control out of the box

I have the same screen off profile, with conservative governor. On the stock 4.0.1 kernel. No problems with this at all. Probably saves quite a bit of battery.

Not sure how effective they are, only second day using the profiles.

Any ways to get better battery life when listening to music?

Title says it all. is there anything I can do to get better battery life besides the basic turn radios off and brightness down? Thanks.

You could try HoloMusic. It's supposed to be the most energy efficient music app.

I use Franco Kernel, and just change the CPU frequencies. I use min 192, and max 500 - great battery life with it!

just connect the phone to charger while listing to music and you wont lose any battery

Actually, i used 192 as lowest step, 1200mhz as max step for a long time, never seen a sod.
The issue lies in maximum freq for screen off, and the time cpu takes to execute stuff in the background.
Min freq can be 192, np. Just control voltage at that freq.

HoloMusic is definitely the way to go, along with custom voltage and cpu settings.

[Q] Underclocking Query

How much can the phone be underclocked while maintaining the stability of the system?
What would happen if i set Max freq to 600 Mhz?
What is the best thing to do to save up the very last bit of juice in the battery for emergency situations where i would only need the phone and message facility? Besides switching off Bt,wifi,sync.
Im asking because i was wondering if underclocking "too much" saves a substantial amount of battery when my battery is quite low and I am "hours away" from a charging port!
And is there a way to change the carrier name on the notification drop down to whatever we want.
Sorry if i sound noobish or if a similar query has been asked before
Thnx.

Underclocking the CPU dramatically isn't going to gain you a great deal in the way of extra battery life because:
1. Unless you are heavily taxing the CPU (complex 3d games etc), the biggest drains on the battery are the screen and the radio.
2. If the screen is off, the phone will drop the CPU frequency right down anyway.
The best way to get extended battery life is simply to carry spare batteries!

Dave

I think 600mhz is way too low and counter productive or for that matter anything less than 1ghz. The phone will lag alot and you'll have freezes. You'll probably end up using up alot of the battery life trying to get tasks completed. You could try leaving the stock clockspeed 1.6ghz, set minimum cores to 2 and slightly undervolt to -25mv, leave the gpu setup to its default 533mhz and also undervolt to -25mv using a kernel that supports stweak app. Then run an app called Stability Test for 10minutes to check for errors.
Also I tried Go Power Master, which can be assigned to disable certain features once your battery hits critical low levels.
