I'm running calks rom, and i have setcpu with his profile settings, i just flashed the the newer kernel in the development section for superior battery charging and it has the "smartass" scaling as an option?
Which scaling governor works best? with battery and performance both in mind
"smartass" or "on-demand"
A lot of people say that interactive is really good. my phone doesn't like to play nice with it. I use performance with screen on, battery life isn't a huge factor for me. I set mine to the lowest possible with screen off. I have also heard a lot of good things about smartass, but I have never used it. I would play around with smartass and interactive and see which one works best for you
Swyped from my dark and cyanogenized EVO
I have mine all set to Smartass.
If you select a governer leave setcpu turned on and let your phone idle with the screen on and watch it.
You don't want you CPU maxing out when it's not in use.
I find smartass to keep it at the lowest clock (245 for me) better than any other governers.
Probably should add, i'm getting 20+ hours off a charge with pretty heavy use. but that's with profiles scaling my cpu down as my battery dies, all set to smartass.
With an evo and fresh 3.5.1, n4.3.1 kernal havs, bfs, sbc, the phone has been running very stable @ 1190 but the smartass setting doesnt seem to be playing too well w my phone after many benches w basic setcpu program "long bench" I have determined my phone runs optimal at conservative and performance. Battery isnt terrible on performance as if I stayed by a router for 60% of a full seidio 3500 would be 48-55 hours. This has been best combo for me for speed and life that I have found. no reboots or basic lockups occasionally for an extended time. Maybe its the way smartass looks for what to do by scaling when performance is all way looking for next task that would help it work. But thats my phone, my old droid reponded very dif to kernal swaps as I flashed many too. Battery life off the wifi more has netted me in the 40ish hour charge point.

I want to over clock my HTC Desire using Set CPU
What should my max over clocking be , and what temperature should my CPU run at to be safe ?
I'm currently using the RCMixHD kernel.
Depends on your kernel.
Also, li-ion batteries are designed for use around 20c-60c, but as it goes past 40c, I think it has higher discharge rate.
Depends on your phone & kernel combo - 1113 Mhz is stable for the most of the people.
I suggest playing around with and test it - 1113+ is OK for some, but if you'll get reboots and the phone gets hot, then it is not recommended.
Also if you are OCing, you'll get more power, but worse battery life.
wont it consume more battery ??
I have Coutts 2.6.38 kernel and it allows me to underclock to 128MHz and 1190MHz overclock and I use ondemand since games don't like other governers. The underclock is bloody great to have as it consumes bugger all battery life and kind of balances out the overclock. However, as nagypapi said, you might not be able to get these speeds since your phone might get hot or reboot. I think people fail to realise that not all devices are the same and what works for one person, might not work for another.
Max. clock should depend on kernel support(if the kernel supports it, then that's your maximum clock). As for temperature, I have a profile on SetCPU which down-clocks the CPU when the temperature reading goes above 36 degree celsius. All other times it works between 806MHz-245MHz OnDemand.

Sort of goes without saying that the higher the CPU cycles the more battery juice your phone will consume and the quicker your battery will drain. I use GingerVillain which supports speeds 128Mhz - 1113mhz and using Richard Trips 2.0b OC kernel (based 2.6.37.4) seems to keep battery alive for a good 24hrs. If it's any help my SetCPU profiles are as follows :
On Charge : 128-1113 performance govenor
Sleep/Standby : 128-576 conservative
Battery < 100% : 128-998 performance
Battery < 75% : 128-883 ondemand
Battery < 30% : 128-652 ondemand
Failsafe Temp > 45.1c : 128-768 conservative
Seems to give me a good balance of speed and battery life, but would be interested to hear from anyone else that thinks my settings are wrong, always looking to improve my phone!

I would like to try this settings, but could you please also add priorities for each setting?
Also what is your main governor? (when you startup SetCPU)
Other thing i dont understand why people use such high cpu freq for battery charging (when its charging and im never using phone then, isnt it better to put some low freq. and power saving profile?)
Same about Standy/Screen off.
128 is too low, it makes my phone slow, 245 is better IMO.

I know it, but weird, when I set the lowest value to 128, my phone's reaction become laggy, but 245 has no such problem. Maybe it's affected by kernel or rom.
sorry for my poor english
I know some roms/kernels have issues with dropping to 128 but my rom seems quite happy with it. I use higher CPU on charge and with battery above 75% to give me the performance when I have the most charge. When my phone boots it will adjust CPU according to battery life or charging profile. The settings seems to work fine for me although battery does drain quicker when I have it fully charged but that's my own fault for setting the performance govenor when I have high charge!

I'm using your way! thanks!
No!
Using any CPU frequency that is not default ( underclocked or overclocked ) requires testing and manipulating the various variables. The CPU needs to be in sync with the GPU and the other parameters. Needs modifications in the kernel itself. The device is not made to run at those frequencies. You will burn your device, sooner or later.
I'm wondering if anyone's undervolted and to what values.
I'm also wondering waht the deafult values are and if they change per kernel.
Is there a way to disable SetCPUs undervolting settings?
Has anyone improved battery life with profiles? On the Eris this was the only way to get usable battery life.
Or not. I gave up undervolting after I actually compared battery life at stock values vs undervolted (on my old phone, sgs4g) and discovered it does nothing for battery life.
Edit: undervolting "might" marginally increase standby battery life, but considering how good this phone already does... it certainly won't increase actual screen on usage.

Depends how low you under volt. Got more battery life, maybe about an hour, after finding optimal battery life on my gfs Gnex.
If you don't under volt correctly, of course it won't improve battery life.
From my sexy white, Nocturnaled HTC One X
If you're not overly comfortable with undervolting, then using one of the many kernels with Smart Reflex will do a mild undervolt for you. If you are comfortable, then the only way to find numbers good for your phone is to try and test. I tweaked mine down to the point that I was occasionally getting hot boots when the screen was off and media was playing. Tweaking the numbers back up added the needed stability. Even little things like kernel or ROM revisions can change what voltage is or isn't stable. Another example is that when I updated my Jellybro CM10 version the other night, along with updating leankernel from 4.1.0exp3 to 4.2.0, I had to increase a few of my voltages to avoid hot boots.
Just for example numbers, here are mine:
Code:
1350MHz -- 1200mV
1200MHz -- 1150mV
920MHz -- 1050mV
700MHz -- 950mV
350MHz -- 825mV
These numbers will vary from device to device and even between ROM/kernel combinations, so don't use them as hard fact.
Thanks. On a phone like this it might not make a huge difference but on the Eris (Where stock battery life could sometimes be 6 hours if you actually used your phone) an undervolted kernel with setcpu could turn those 6 ours into 48.
Thanks Cilraaz, I'll try those voltages out and benchmark a bit to see if they're stable for my system.
Two things I can say for sure:
1. you will have very limit battery gain by undervolting with Gnex, no matter how low you try.
2. undervolting will bring some stable issue if you get too low, like lose signal and reboot.
I am using Kernel Franco GPU 384 Stock rom on my 4.1.1 and did undervolting
Current configuration:
384Mhz
950mv
------------
729Mhz
1050mv
-----------
1036mhz
1125mv
----------
1228mhz
1275mv

I did not change the frequencies of overclocking, because I'm not using them.
I felt an improvement in battery consumption unless the unit is heating up.
Just curious - what kind of profiles are you using? I have a "Screen off" that's 350min and 700max. I figure that's fast enough f someone calls me.
I've read many times undervolting isn't worth it.

I'm using the following with SetCPU: default (1350MHz-350MHz), charging, CPU temp > 64, and battery < 35%.
If you're using a kernel and governor that support hotplug, then you likely don't want to use a screen off profile. The combination of the two can tend to cause sleep-of-death or hot boots.

Most people don't want to spend the time to do it right.
I'm actually not used to the new kernels. I haven't messed with my eris in about a year and back them there was "smartass, on demand, performance," and some other one that clocked down instead of up
Can you explain th escreen off profile causing issues? I don't even know what hotplug is lol I've been out of Android for a long time.

Hotplug disables one of the CPU cores when the screen is off. Some governors, like hotplugx, will also attempt to disable a CPU core during periods of low CPU usage. For some reason, this combined with a screen off profile can cause some problems. I assume it's because of the "screen-off-max-freq" that Imoseyon mentions in the quote below.
Personally, I prefer the interactivex governor with leankernel by Imoseyon. From his kernel thread:
With interactiveX V2 (for gnexus), things are a bit different, since gnexus has built-in support for screen-off-max-freq for all its governors. I took the new interactive code in gnexus, added early_suspend support (screen off/on trigger), and then added logic to the code so the governor uses the phone's built-in hotplugging capability to turn off cpu1 when screen is off (and then turn it back on when screen comes back on). Cpu1 goes offline entirely - no idle, no sleep.

I think undervolting helps - my phone is running 728 - 1228 using the interactive governor, with voltages of 600 mV, 700 mV, and 800 mV (728 MHz, 1036 MHz, 1228 MHz respectively) and I haven't had any issues so far. I know there are some reports that say undervolting doesn't help much, but those are when people undervolt by like 50 mV, whereas here I'm going like 400 mV under lol. (Yes, smart reflex is off).
Thanks Cilraaz. Good to know.
So turning the screen-off profile could improve things? Honestly, my system does fine at 350mhz with screen off. Turning a core entirely off would probably help though.
If I use hotplugx governor that would disable one core when the screens off, right?

Hotplugx will disable a core when the screen is off or when there is low system load. Depending on your kernel/governor choice, other governors may do it also. On leankernel, for instance, interactivex will disable a core when the screen is off, but not on low system load.
Ok, thank you.
I haven't done any comparisons of before/ after since I undervolted/ underclocked first thing. But I was browsing for hours while listening to music while talking to a friend with GTalk. talked for about 1.5 hours with someone, Left it on overnight (10 hours), woke up, used it to talk (voice to text) to someone via GTalk, and it's 3:25PM right now and I still have a fair amount of battery life left.
I'd heard mixed things about the battery on this so I'm happy.
My voltages:
1650: 1300
1520: 1250
1350: 1175:
1200: 1125
920: 1000
700: 925
350: 900
I stress tested each one without a crash.
Hey guys, I'm just wondering what settings do you have on your setcpu for the best performance and battery life? I'm totally new to this lol

i i think that ondemand is the best for daily using... i'm using cm10 rom and i have some music problem so i'm using interactive and it's ok. if you don't use games or heavy apps, you can underclock it to 1ghz or even less and put on powersave.. but you have to try and find the best for you
My setup is a little complicated. I use the ondemand governor, then for the profiles I make it use powersave and under 760mhz between 1am and 8:30am which seems to really help during the night. Also set it to use 760mhz max when the screen is off.
When charging or above 40% battery I allow it to run full speed, but only when the screen is on, therefore helping charge times. On charge or above 80% I set the governor to performance.
In call I set the clock to max 1000mhz and conservative to try and allow calls on low-battery to work properly without lag but also without killing the battery.
I have a couple of other options set for very low battery ( < 12% ) too, but those are only to extend the battery if it's dying.
I wouldn't say all this is necessary... but I need my phone to keep working at all times as I use it for receiving business calls.
It's just a matter of playing around really... depends what you use the phone for. For the most part tell it to use lower clock speeds when you don't need them so much (when phone is off, during the night, during call etc) but you will really notice the speed difference if it's underclocked while you use it, so I tend to allow it to use full whack when screen is on, unless the battery is low.
I also set up profiles to make things like Bloons TD4 run in performance mode and min of 1000mhz, to keep them smooth . Drains the battery though!
lol setcpu does a really good job at battery saving. When using ondemand, my phone can last more than 2 days (if it's on standby)
Have you guys tried under-vaulting? What does it rlly do?

If you mean decreasing the voltage on the CPU, no I haven't. From my experience in desktop PCs however, if the CPU voltage is too low it can lead to hardware issues and instability.
If something needs a certain amount of power, and you give it less, it will either try and draw more amps which increases heat and can fry components, or won't work properly. You could probably "under-volt" the CPU at the same time as reducing the clock speed however, but your performance will suffer. When the processor is set to be ondemand it underclocks itself when not in use anyway
The biggest battery drain is screen and radios, concentrate on using them less. Underclocking the CPU will make the phone last longer when in use, but usability will suffer and turn your super fast smart phone into a sluggish one. I only make mine stay underclocked when the screen is off, during a call, or on low battery. During general use I let it do its thing .
UV(Under volt) is actually not to bad. Don't ever set those values at boot, else when they are too low, it will cause BOOTLOOPS. It just reduces the amount of power allowed for the cpu to use, thus it won't use more than required. You can't really ask a person for his/her uv values, as no 2 chips are created equal.
People stating that they UC(underclock) their device is not quite right. We don't have much control over our cpu's to be honest. If you run tegra stats whilst using you're phone, you'll see what I mean. It will sometimes(happens quite often) just bump up to higher frequencies to which you UC them. Also as soon as the screen is locked and unlocked the max cpu frequency set by the governor will just return(for example: say stock is 1500mhz, and you set it to 1400mhz, it will return to 1500mhz after an unlock). Ondemand is very very good for battery and performance. But remember you have to tweak those values individually in order to optain the best possible performace for the given task you want. Whether it is for battery or performance.
It's actually also a lot better to just tweak those values as to TRY and uc. Uv will stick, UC not!
Here is a small example as to battery saving and performance values for ondemand governor:
sampling rate:---------60 000 ----- 30 000
up threshold:--------------95 ----- 60
sampling down factor:-------2 ----- 8
powersave bios: ------------3 ----- 0
ignore nice load:------------0 ----- 0
io is busy:------------------0 ----- 0

afaik and base on their details. personally, i use interactive+row on stock then smartassv2/ lulzactive+sio on custom.
SmartassV2:
The motto of this governor is a balance between performance and battery
SavagedZen:
Another smartassV2 based governor. Achieves good balance between performance & battery as compared to brazilianwax.
edit:
Q. "Ok. Enough of explanations. Tell me which governor is for performance and which one is for battery life."
A. Tough question! lulzactive and smartassV2 for a balance between performance and battery. For light weight tasks, lulzactive should be better for battery. And for heavy weight tasks, lulzactive should be better for performance also.
NOTE: It's not so easy to tame luzactive. If you don't know how exactly to do it, stay away from it or you will end up complaining about battery drain!

I use SmartAss V2 and SIO as governor and scheduler.
Like you, my wifi is permanently on, but screen is not on for long periods, and using this combo since Alpha releases of CM10 onward I have had good results, getting up to 2 days plus on CM10 EOL, and currently on LiquidSmooth 2.9 am getting well over a day from a charge.
Performance is good and LiquidSmooth ROM runs beautifully at stock CPU speeds (I currently use educk's Phenom Kernel ported by Madridii with 370Mb RAM, but have had great results with any Madridii kernel)
