Any idea how to underclock I've heard it increases battery life?

If you are using a custom ROM then the ondemand governance will take care of the underclocking when not in use and increase the clock frequency when your usage demands it. That provides reasonable battery saving while not compromising on performance.
Fixing the frequency to a lower limit might increase the battery life but has serious performance issues. Might be handy in critical battery saving situations though.
SetCPU, CPU Master etc.. Such apps can let you modify the upper and lower clocking limits.
Cheers for the replies,where do I get the oc,as for set CPU..you mean one of killersloths kernel scripts?
Sent from my Desire HD using XDA App
Most of the kernels that you can find in the development section have OC scripts already in them.
SetCPU is an app and can be found in the market : https://market.android.com/details?...wsMSwxLDEsImNvbS5taHVhbmcub3ZlcmNsb2NraW5nIl0.
keep in mind that undervolt = giving less power to CPU = can cause damage overtime or reduce battery life.
I mean all these undervolt things don't increase battery time by a huge difference than stock and risking your CPU for just 15 minutes of battery life isn't worth it in my opinion...
Hey there ,
so i wanted to share share my awsome Undervolting results with you
At first im running on Chasmodo's latest CM 10.1 i really appreciate his work ! I use the latest CM 10.1 Kernel.
With his rom and this voltages u find under this introduciton text i could get nearly a month with Standby time
(without doing anything , Wlan turned on , Data off) i attached a screenshot (29 Days and 5 Hours sorry for the German language)
Every day i plug my N7000 out from the Loading station its 5am on 3pm i lost 1%.
to change the Voltages i use SetCPU (full version)
1400 MHz
1200 mV (Stock: 1350mV)
1200 MHz
1100 mV (Stock: 1275mV)
1000 MHz
1000 mV (Stock: 1175mV)
800 MHz
925 mV (Stock: 1100mV)
500 MHz
900 mV (Stock 1000mV)
200 MHz
800 mV (Stock: 975mV)
So i dont know my Voltage group sorry guys , if this values are not working just go in 25mV steps lower from your stock voltage
until the CPU gets unstable or crashes than u know that u cant go lower just do this with every clocking !
I also used this voltages on XXLSC Ultimate Rom with the HydraCoreNirvana Kernel i had fantastic results too but not that good like i get with the Asylum CM 10.1.
PS: Just this Voltages wont give you very good Battery life if your Rom / Settings is/are eating your battery. If you get better results with
lower results (stable) just go ahead and post it but im sure this values are nearly the lowest stable u can get
Code:
Its [U]impossible [/U]to hard brick your device with Undervolting , you only could get a soft brick if you use (Set on Boot) and your voltages will crash your System after boot. thats easy to fix just after the phon booted up fast go into SuperSU and delete the root rights for your Undervolting tool.
Thanks for Reading and if i you liked this push the Thanks button =) !:victory:
Thanks man
I think you should say which Voltgroup (A, B or C) your note is. Because those freq are really low (I think too much low for my note, that's voltgroup B).
Do you remember which voltgroup has your note, when you installed hydracore kernel?
Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

Hey there i dont remember never looked at the Voltgroup sorry so there is no other way to view my Voltgroup ?
Btw just try the voltages without autostart and u will see if your system reboots or if it works if not just go in 25mV steps higher :highfive:

It's a feature of the hydracore kernel only I think, because its read a particular value (something about mainboard and/or cpu) and the kernel automatically apply dedicated undevolt values. You could see it in system information, where hydracore kernel is detected. Without it, I think you can't do anything :/
Anyway, sincerely I remember some time ago I tried to lower my already undervolted cpu voltages, and I got freezes. I will try to go lower a bit, hoping it will works. A very important thing, is not only the lower battery drain, but also the lower cpu temps.

I bought rom toolbox full sometime ago, when there was sales. If I remember correctly, there is a section relative to the cpu control, but I don't remember if it was undervolting capable also. You should start to search it from there (I'm sorry, I don't have the app installed anymore, so I can't help you properly... In case, use voltage control app)

What do you mean by Rom Toolbox doesn't have voltage control?
Tap kernel tweaks, then any frequency and you'll find a voltage slider in there.

never had any problems and just logical cpus could brick if you give them too mutch voltage , if you give them less voltage the system only can crash your sound could have been beacuse it crashed so really u cant hard brick your device with undervolting ... maybe a softbrick if your unstable voltage settings are on autostart.

Hey there , you cant uv with Philz kernel just read his thread check his FAQ there hes writing that hes not supporting
oc/uv its just a repacked stock kernel
use HydraCoreNirvana but when you download the kernel check that its the OC version if not than you cant change your voltage like with Philz kernel.

Just use tegrak ultimate Overclock app. I bought it because I think it's the only who give you the possibility to Undervolt the gpu also. Initially, philz kernel wasn't supported, but now it is. I undervolted my cpu setting the values that I had using the hydracore kernel oc. And today I lowered them of another - 25mV also. Everything works nicely until now

Nice attitude you are showing there. Oh, there is plenty of power, let's waste.it! Really, that kind off attitude is definitely going to make the world a better place
What's more why do you think undervolting does influence the performance? It only influences the power consumtion and if you go too far it does render the phone unstable. But it certainly does not in-, or decrease the cpu's performance.

Yep tegrak definitely does the trick with PhilZ kernels. I have been using it for at least 8 months now and my phone is undervolted too. Only the highest cpu state is overvolted because I overclocked it to 1552 MHz instead of 1400.

Please explain why you overvolted AND overclocked the highest cpu state. Doesn't this shorten your batteries performance?
Did you changed cpu governor or something else (like screen off profile to reduce CPU) to achieve 1% battery loss at 3pm?
And was that with mobile data on?

I overcloked the highest cpu state from 1400 Mhz to 1552 Mhz because I want more performance. And because my phone became unstable with the 1552 Mhz and the standard voltage. So now my phone saves energy when the lower cpu states are active and it has a bit of extra power at the expense of battery life when it needs the most processing power. All in all that gives me better battery life than with stock settings and a snappier device when needed. For me this is the ideal solution.

Default settings are fine for a decent battery life. UV doesn't really increase the battery life; its used to reduce the heating when using processor intensive apps (games). But if you don't know what you are doing, its recommended that you don't change any settings.

I haven't notice any significant increase in battery life, if any. However, the device runs so much cooler than before.
I am now experimenting with 150mV UV. Haven't had any problems with stability or camera.

Undervolting can somewhat increase battery life. Undervolting is meant for lowering CPU power to reduce thermal heat and it will definitely increase the life of the CPU. It doesn't really increase battery life, it might save a little bit but not much.

Do you have the hotplug control in Frequencies/Voltages menu? It seems to be not there for me. If I flash it with stock kernel then the hotplug control is there but can't change anything. If I flash it with Franco's kernel, then the hotplug control is missing.

Something similar happened to me while I was using faux. You have to flash the rom first and kernel later. If you flash kernel first and then the rom some of the features on kernel settings might disappear.
Hotplug is available since quite long time.
Nothing to do with flashing Roms.

thought I'd bump instead of starting a new thread.
what's the best settings for the cpu hotplug control? I've set suspend frequency to 384000, suspend frequency is the CPU frequency when the screen if off?
cores on touch is how many CPU cores get used when screen is touched? I kept this to 2.
now I'm not too sure what first_level is used for though. so I left it at 60.
the new app is good but lacks description for some of the settings.

Do u want to apply the 'best settings' to increase battery life or performance? And I'm using the ones you have stated, pretty balanced stuff. Keep it that way
Battery life on this phone is abysmal - on a fresh phone. Didn't restore much from titanium backup.
Would like to drop the CPU down a good 25% or so, can this be done without too much stress? It's an unbranded, rooted i9505 in Australia.
I suspect I'll need to flash something to do so, is that right?

Define "superb" for me.
Apologies for jumping in here. Can you define abysmal too? I would say my battery life is more than double my S2 (that was Cyanogen niggtlies but this is currently djembey's slim). Biggest drain is usually the 3G but I have that off most of the time. It is hard to compare to be fair as we will all use different settings but I have a lot of the bloat removed or disabled, power save on and screen at half brightness. How is yours setup as maybe we can shyc settings a little to compare more closely.

If the reason to underclock is to save more juice, you should understand that the phone doesn't work on 1,9ghz most of the time, on average it's 200-800mhz depending on task, so you would not probably win a lot battery if you underclock let's say to 1.7 unless you're a heavy gamer.

I know this tread is already pretty old, but that answer is only partially true.
On stock configuration the GS4 uses the 'ondemand' cpu gouvernor. That gouvernor ramps up the cpu speed to the max when cpu activity is detected and will then slow down the cpu depending on the task. So everytime you open/close an app the cpu is running at 1.9ghz. (At least that I heard/experienced) using a custom kernel you can choose a different gouvernor which is more battery friendly, or lower the max cpu speed(from 1.9 To for example 1.7ghz). You can also lower the min cpu speed so that when the device is idle, it will consume less power (I think standard is around 350mhz and I put mine on 189). Some kernels even allow to underclock the GPU. Undervolting will also save battery.
In short: using a custom kernel you can really save some battery, increase performance, or get a better balance between the two, but you will have to take the time to find the settings that work best for you. I personally use KT kernel, with an overclocked CPU and GPU, but I also undervolted them both by 75mV, and with some tweaking with settings for when the screen is turned off, my battery lasts longer than stock configuration.
Correct me if I'm wrong on something, I'm not a Cpu expert
And sorry for bad english

Check this out, if you long press the power saving icon in the notification pull down, it will bring the settings for it, Uncheck all but the cpu. It will run no higher than about 1.3 ghz and is plenty fast for all tasks. I use that setting on the s4 and note 3. I never ran into any lag except TouchWhiz home launcher but I use Nova Launcher anyways.
You will see a better battery life as well.
Currently running 4.4.2. stock with ART enabled. This combo suits me well in terms of fluidity and everything works great. Now I would like to have an option on disabling 2 cores to extend battery life. is there an app to do so on stock kernel and is it even possible to do it on some custom kernel? If there's no option to do it on stock id like recommendation for custom kernel that works on stock rom and would enable me to do this via some app.
And id like that ART can stay enabled.

try a custom kernel like ak or hellscore
after that disable 2 cores using trickster mod/kernel specific app
Yes, Darkrai is right. Test a custom Kernel like AK, Matr1x, Hells core, Franco or Faux.
You can easily flash the zip via recovery. After that, you should download a Kernel App like Trickster Mod or Kernel Tweaker from the Play Store to customize the whole kernel, gpu, cpu, govenors, schedulers (2wake) etc. And also the cores of the cpu. But you need not to stop 2 cores, you only have to underclock the cpu, so you have all 4 cores but they, for example stop at 1ghz, which save battery at all
I don't really think it helps your battery life (a lot).
More cores at a lower frequency are more power efficient than less cores that have to work at a higher frequency to get the same job done.
And hotplug is there for a good reason, if cores can sleep they will.
Or does anyone have personal experience where it really helped a lot?
I don't understand why people complain about battery life. They say 1 day is not enough, well it is considering their usage.
You can easily pull of 2-3 days without playing games. The problem is that everyone spends like 2-5 hours looking at their phones every day!
On topic: If you want to have performance and fluidity with 2 cores, you will save 0% battery because cores will work on higher frequencies. Just try not to using your phone 24/7

Short answer: No.
Long answer: No. But you can undervolt them (All 4 of them at the same time).

Try Franco kernel ... it by default supports dual core mode ... moreover u can play with hotplug values according to need
You can using a custom kernel, lots include the ability to but the best implementation is faux's eco mode which is found in Faux's kernel and Ak kernel.

No big difference with other custom kernels where I was using all 4 normally. And the worse about 2 cores is the lag at many applications.

Great, its the kind of discussion i hoped to start. My logic was that n4 might have enough cpu power for surfing and casual usage with 2 cores only. So if i disable another 2 i might extend battery life.
Its great some of you tried and show me that my logic was flawed
Now undervolting. I suppose that i cant fiddle with stock kernel and undervolt cpu? Any recomendations for custom kernel. id like it to be as similar as stock, with undervolting feature enabled.
And are there any real gains in undervolting?

Many custom kernels support uv like Franco, hell God etc.
Uving is offering a little cooler cpu, which means more time till thermal throttling to start.
Let's say it helps system in general, but not something to notice in big way.

Undervolting brings much more than turning off cores. As a side effect your phone won't heat as quickly under heavy load.
What will save you a lot of power while having the phone awake is screen brightness. So you should look for a clever auto brightness solution or, like me, use a mod that let's you adjust brightness by swiping the status bar. I keep my screen dimmed to the low at all times and only make it brighter temporarily if I am outside and the sunlight blinds.
