it does, just prolong it from heating...once the phone get hot enough, it will start to thermal throttle which downclock your cpu anyway...i tink the preset is 902mhz and 712mhz(?) not a good phone if you wanna play game long...

Stock kernel on leaked .407 (Jelly Bean 4.2.2) doesn't support undervolting.. :thumbdown: so I am pretty limited atm. And moving back to 4.1.2 isn't ideal because of wakelock issues on latest .253 and .307 Firmwares..

under clocking is essentially undervolting, but undervolting too much lag the phone.

Nope, underclocking is lowering lowest and highest frequencies that the CPU can provide and use for certain tasks.
Undervolting is lowering the voltage frequencies of the CPU cores at their CPU frequencies so they drain less power from battery. Lower this too low though will cause lag and reboots because less power to the cpu..

underclocking using a lower freq, since the freq have different voltage, the lower the freq the less voltage, since you are using a lower freq you are using a lower voltage.

Not necessarily. It is quite often that the voltage between two neighbouring frequencies doesn't differ.
Besides the voltage differences between highest frequencies are small so to effectively prolong your battery life by underclocking you'd have to limit the CPU a lot. So usually undervolting is the way.

Undervolting or underclocking - which one of them is best?
Sent from my C6603 using xda app-developers app

I'd go with undervolting. You get the same performance and longer battery life but it might cause reboots if you undervolt too much.
With underclocking there's no rebooting issue but it's simply limiting your phones performance.

[Q] Laggy games?processor running at 1000mhz max?

i m on v10D, i just rooted and intalled setcpu, 1500 max 1400 min gov: performance, now just after i restart/turn on my device, the frequency is right..but then after a couple of minutes it drops to 1000 mhz..i have 2 questions:1.is there a way to fix this,2.does any other version( other than v10D )offer better gaming experience...and if so, which is the best?
Thanks for your time :good:
Well i have mine when I game set to 1500 low and high plus performance. It never drops and other then that. One issue I did encounter is that as long u have profiles set up and checked it will still use them regardless if u set it in the front page to a certain speed. So u need to uncheck all profiles and also uncheck the use profiles. Basically uncheck it all then even if u uncheck use profile it still will use the profile if u select one. Here a picture from what I mean. See how I unchecked everything. U need to do this to or it still will the profiles even if not checked the use profile box.

It didn't change anything for me to put the CPU @ 1,5GHz constantly. I did a test with the game Horn and its lagging exactly as with the default CPU governor enabled.
If you think about it for a moment, it makes sense, as the GPU is doing the majority of work.
Tegra 3 CPU Clocks
Based on what I understand about Tegra 3 from this thread- http://forum.xda-developers.com/showthread.php?t=1664391, the CPU has 3 different "modes". 1.5Ghz single core, 1.4Ghz dual and triple core, and 1.2Ghz quad core (At a certain temperature, remains on 1.4Ghz or 1.3Ghz until that temperature is reached... quickly). The reason why the frequencies go down is because when the phone is utilising more cores, the frequency drops too. The move from 1.5Ghz to 1.4Ghz causes lag in games at times, which is why the maximum should be set to 1.4Ghz to prevent this from occuring. Also they said that the performance governor causes 2 of the 4 cores to no longer be in use, which is NOT good for Tegra games such as ShadowGun as all 4 cores cannot be used, so they advised people only to use it for Non-Tegra games as they do not use all the cores. Hoped I helped in any way, even though I'm a new guy. I'm not sure if this applies for ALL Tegra 3 devices or just the HTC One X, but it still looks like useful information.

Thanks for your reply..but for me, the frequency doesnt drop to any of the values above, it automatically drops to1000 and mostly its on 1 core
Which brings me to another problem...i need a way to force the activation of the 4 cores simultaneously...in most games the cpu is stuck at 100% single or dual core

Most games are not optimised to use 4 cores, so I guess using only 1 or 2 cores should be normal. What governor are you using for games, because this might have an effect on the performance.

I tried all governors..performance isnt the best, idk why..userspace seems to work fine, but still when i set min and max freq above 1000mhz, it automatically drops to 1000mhz ._. and that isnt quite good for gaming, and since i bought this device over s3 for gaming, i feel f*cked
so would an update to v10F or a hard reset fix anything??
EDIT: and there 's 4 other people with the same problem and one of them has v10F so hardware problem??if so, im hanging myself

Nexus 4 Undervolting

I've always been a big fan of undervolting. These are the lowest voltages I can get stable at these common speeds. I found I can underclock the Matr1x kernel further than some others I have tried for some unknown reason. How low have you been able to go? Also, what programs do you use to test stability? So far, I have been running Antutu test completion as a measure of stability. Any suggestions otherwise?
288MHz - 650mv
1.02Ghz - 800mv
1.51Ghz - 1000mv

Kernel: Matr1x 6.5

To increase battery life,
The Long answer is that the CPU has a number of parameters where Clockspeed (MHz) and voltage (mV) are two. Clockspeed, well that is speed. Voltage is related to the amount of energy provided to the cpu, undervolting means that you feed the CPU less juice but demand that it runs at the same clocks. You are essentially starving the CPU,it uses less energy, but can become unstable if the voltage is insufficient to maintain operations. Manufactures always have extra voltage as a safety margin so power users can check their CPU bin (slow, normal, fast or faster) and lower voltages step by step until they crash the phone during a stress test, increase the voltage slightly and boom, your phone uses less battery power while being just as fast.
I undervolt to reduce heat. It makes a significant difference. The battery saving is minimal, but the temperature difference is VERY noticeable.

Took words from my mouth. This this and this. It reduces heat, which in turn reduces battery use. UV by itself doesn't save a lot of battery, it's the consequences of it. I'm normally not a fan of UV, but with current N4 sw/fw it NEEDS it. It's way too high.
Interesting observation. As of recently my phone jumps up by 3-5c from 37-38 hover. Never used to do it before, not until i got it up to 50c for about half an hour last week. Previously it would stay steadily at 37-38, now it spikes up now and again during use. What's interesting about is that once it goes over 40c battery use increases drastically. So i wonder if people that have really good battery life don't have phones that go over that temp often and vice versa.
I haven't played around with the values too much yet, just a -100mV across the board. This seems to work just fine, so I might experiment some more..
Using Franco test-r69 at the moment.

I undervolt to prevent heating like others say. My Antutu scores drop like a rock when I'm at stock clockspeeds mostly likely due to thermal throttling. Now I can run it repeatedly without having scores drop. It saves battery and runs faster while running games even for very short periods of time, so I am a big fan of undervolting. :good:
Undervolt to reduce power usage, think of the stock voltage as normally being more than is required, think of running for a bus yet you have 2 minutes why waste energy when you can walk and still make it .
Undervolt for less power usage and less heat produced meaning battery performance is better (cooler battery is a more efficient one) and performance is up as you avoid any thermal limits in place .
Great stuff undervolting, I have managed to get -150mV across the board ( 1.5ghz @ 1000mV) and 288mhz is 162.5mV .
I came from a nexus s ... And one member of xda went to amazing lengths to show that undervolting really made very little differences in battery life ... And it def wasn't worth the instability .
He did loads of tests and I mean loads and basically showed that in helped so little that if you had a reboot you would use more power in rebooting then saving via undervolt
However . it is worth it for the heat decrease for sure

The more the heat, the faster the battery drains. Since undervolting decreases heat, im sure it should increase battery life. Maybe not for browsing or calling, but playing a heavy 3D game.
is it normal that the higher the frequency the lower the voltage in setcpu?

You can do it from franco kernel updater, from frequencies and voltages - voltages - cpu voltages

Former nexus s user here, the reason nexus s didn't benefit in battery life much was that it only had 1 core, and used a higher nm manufacturing process, 65nm -> 28nm. Lower voltages in the 28nm means that it multiplies the heat/power savings more than a 65nm, and the 4 cores multiply the savings by up to 4.

Download system tuner or get this app: https://play.google.com/store/apps/details?id=com.teamkang.fauxclock
And then just look at your cores. 97% of the time there is just 1 core working (on my phone).
Faux's app is about the same as CPU Spy, but Faux123 Kernel Enhancement Pro can also tell/show you the amount of time that all 4 cores were being used. Which is really barely never. If it's different in your case then you could do some tweaks, but I really doubt that it will be different then my phone. In the end it also depends what you use your phone for of course.

Overclocking

So, I overclocked my CPU frequency to 1836MHz and my GPU frequency to 450MHz and after playing a game for like 10mins, my phone gets really hot. I know its normal but I would like to ask, did I overclocked my phone too much that it can destroy my phone? And what is the overheat temperature for my phone(HTC One)? So I can monitor it.

Yes its possible to permanently damage your phone if your overclock is too much aggressive or your phone get to hot. Every chip is slightly different so you'll have to test your phone for each frequency steps you do. Like a computer, you should start overclocking in small increments till you reach a maximum stable config and then reduce it a bit for safety. And always monitor temperature, over-temping is your worst enemy when overclocking.
For the max temp question I don't really know, you might want to check qualcomm site for max safe cpu temps. Don't forget some other components doesn't like high temperature. Semi-conductors components life are reduced in high temp conditions and generally, lithium-ion battery doesn't like high temperatures...

Guys,
I'am wondering if its possible to set min CPU to lower than 200Mhz????
I used to have a HTC Incredible S and lowering the min CPU to 133Mhz it helped with battery saving.

Hi mate,
Have you tried playing with the CPU frequency settings located in:
/sys/devices/system/cpu/cpufreq/pegasusq/
You will need Root Access and to mount the System as read/write in order to save the changes.
They are also referenced in /init.rc, so you can probably change the settings in the Kernel too
Have a great day!

if this trick works you can set it to 1MHz....But the big question: will the phone work normally? i mean if i get a call phone will act as normal?

No, in deep sleep the frequency is different. That's why a idling device wastes more battery than a deep sleep one.
