I use xperia x8 and i have nAa11 and 2.1.9 CM7... I have the processor speed, my minimum speed is 600MHz, 806MHz is max speed... I am interested in what else I can do or put on my xperia x8 to be a better, more beautiful or fast?
When it comes to speed, I think you have reached the X8's limits. There is only so much the devs can do - and for the record, they've done a far better job than SE (I guess it's just S now) will ever do.
Why 600Mhz for minimum speed? That will drain your battery very fast.. I have my minimum speed at 19Mhz and my phone is smooth as butter.. Your governor will raise the speed when needed.

Well, i have nAa too and no reboots at all. Because i don't overclock i also undervolt which also helps saving battery. One thing i like is the fact that phonecalls always use 19MHz
What governor are you using?

Hey guys i am currently using CM7 kittenlinux base (in fact autoradios cm7 light ics modded)
I just want to know which is a safe overclocking frequency for the mini. I plan to use 710hz but u guys tell me =)
Thank you.
Each phone have not same. ...not every phone stable in the same MHz like i am not stable in800MHz...but someone is stable..so try it by urself...and dont overclock too much...waste battery
Sent from my GT-S5570 using XDA
i always use 729-748 as max cpu frequency and the lowest frequency as min cpu frequency... as governor i use ondemand or lilgV2... for me works fine but you should find your own configuration because it depends from the use you mean to do with your device... for example if you use you phon for gaming so you need high freqency for lagless gaming experience but a governor and a shleuder that make long battery life... try by yourself xD
For maximum freq 710, for minimum freq 245 (less chance of hanging when waking device) and governor smartassv2. That's how I roll

By putting phone in horizontal position, display facing south-west, and perfectly balanced lol but really, you'll notice how it performs, any fc's or hangs or random reboots are bad signs
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
ROM: Bionic AOSP V3
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
But i dont recommend you to undervolt if you dont know what you do.

How are you able to undervolt with SetCPU? I'm not seeing that option using CM10, and Harsh's kernel.

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.

Go for stock rom with stock kernel.
It gives the best battery backup..
Or you can also go for primehd with naa kernel..

I think PrimeHD 10 with nAa-14 be the best power saver combination.

+1 "he's always right!"
And I could use my phone three days without simcard on gingerdxv31 plus nobodyAtall's nAa14 super kernel(medium usage ,2 hour gaming ,1hour music ,20min video ,1hour other #and still I've been got 20% left!?!)
In my opinion every rom has almost the same performance , all you have to do is to select "ondemand governor " + underclocked min freq to 19 mhz max to 480 or 600 , and cpu undervolt option (gingerdx31 doesn't suppurt this feature)
Currently on minicm10 ,drains battery like a monster! :/

Not so much diffrent comparing to 120mhz - 600mhz but phone will wake up a little later
(If you wanna play games set max to 600 or higher otherwise 480mhz is enough for scrolling , browsing ,running apps ,because our ram and I/o is slow so the cpu clock speed won't be important here)
#Voltage usage in diffrent freq:
320mhz=3mv
480mhz=5mv
600mhz=6mv
729mhz=7mv
#480 uses 20% less energy than 600 I think
#On sleep mode freq will stay on 19-120 mhz most of the time so its very helpful for saving energy.
(Usage on gb might be diff. Cause these numbers are for minicm10)

Hello all,
I'm planning to buy a Xperia Z but I'm also interested by the Xperia ZR that has a better battery life but that is harder to find where I live.
So I'id like to know whether the Xperia Z has a good battery life, let's say a day in advanced use, and no lags if underclocked @800-1000MHz.
Thanks in advance.

If you buy an unlockable device (not from a carrier) undervolting with a custom kernel will make the most difference
@ kingvortex: Thanks for the link but I'd already read the thread and I didn't really find an answer. I saw that for some users underclocking wasn't working properly... Does the problem still exist ?
@ DrKrFfXx: Yeah I won't buy it from a carrier, and I plan to underclock the Z if I buy it, freeze or unistall some apps etc. But I don't want to lose performance. Is the interface and most of apps very smooth at 800MHz ?
Thanks.

Is laggy at that speed.
But don't confuse undervolt with underclock, mister.
Undervolt as the name implies, is lowering the voltage of the processor to generate less wattage and thus, less heat and battery consumption.
You can undervolt your device to consume the energy of the stock 1000mhz and retaining 1500mhz. Undervolting combined with a slight underclock, say to 1350 will achieve decent performance while mantaining great battery life.

Yeah I knew it, that's just a habit for me to say underclock ^^
Anyway thanks for your answer. If at the end of the week ZR isn't available here I'll turn my choice on the Z.

I'm using iodak v7. It gives great performance, smoothness and CPU throttle doesn't kick in until high temps like 80-85 are reached. Most games reached around 80 max in my case and cores were still running at 1.5GHz. I really love this because it doesn't cause lags! Try it. Btw, while gaming, I OC CPU to 1.7GHz and GPU to 600Mhz which gives additional performance.
