Hi all,
Has anyone tried using SetCPU on his rooted legend? I tried on my non rooted one just too have a look at the CPU frequencies, to see how it behaves at idle and so, and while max is 600MHz the min is "only" 480MHz.
Doesn't that sound a bit high for the min frequency? The snapdragon is clocked at 1GHz and idle is 250Mhz. Has anyone tried lowering the idle frequency on the legend to gain some battery life?
Hi Bricolo_fr,
I found this entry in the FAQ of SetCPU documentation fount here (http://www.pokedev.com/setcpu/):
"Why aren't there more speeds to choose from?
The speeds which the CPU can run at is in part a kernel limitation and in part a hardware limitation. Attempting to set the CPU frequency to anything else won't cause any changes in CPU speed. On some devices, the kernel can be modified to enable certain other frequencies. There are other speeds that would be useful, the capabilities of the processor itself often hinders which frequencies are available on a device."
Anybody has the skills for making a kernel change?or some ideas for us being able to use this properly?
Hi,
Today I rooted my legend and tested again SetCPU. At the begining, it was only possible to set CPU from 480 to 600 mhz, but then I red this in SetCPU documentation:
http://www.pokedev.com/setcpu/
--------------
10. Disabling Perflock
On most stock HTC kernels and some custom kernels, HTC has enabled a driver called "perflock" that constantly resets SetCPU's Max and Min settings. This does not apply to mostly "Google experience" HTC devices such as the T-Mobile G1, the myTouch 3G, any Google development device, or the Nexus One. It does, however, apply to "HTC Sense" devices such as the HTC Hero, Droid Eris, HTC Desire, HTC Incredible, EVO 4G, and myTouch Slide. Non-HTC devices never have perflock enabled.
SetCPU can disable perflock on newer HTC kernels, giving you control of the Max and Min settings of the CPU. To do this, press the Menu button on your device in the Main tab and choose "Disable Perflock." Read through the notice and then press the button in the dialog. If successful, you should be able to change the frequency with SetCPU. If this process fails, please e-mail the developer with your kernel version and device so support can be added.
Keep in mind that disabling perflock does not enable overclocking, though some overclocked kernels may require perflock to be disabled. Overclocking, in most cases, requires a custom kernel.
-------------------
So, in the last version of SetCPU there is an option in the menu called "Perflock Disabler" With this option, it is possible to select the minimun frequence to any value from 0 to 600 Mhz.
I have not been able to modify maximun to a value higher than 600 mhz (overclock) but I think the best target is to reduce battery consumtion decresing the minimun mhz value. Actualy I set minimum 128, maximun 600.
so, are you sure you could set it to the minimum of 128? because i think it doesn't work actually...at least without a modified kernel
I got a min at 19 MHz. to 600 Mhz.

Yes. Also confirmed with the app Os Monitor:
-Saling range: 122880-600000
-Frequency range:19200-600000
-Governor: ondemand
-Current: 122880
Software version: unbranded 1.31.405.4 (just rooted with Monodaco method and applyed all OTA updates)
In SetCPU Info:
-Time in state:
19200: 22
122880: 1169071 (Currently I set minimum at 122880)
128000: 0
245760: 269491
480000: 362472
600000: 347583
SetCPU in Legend allows the following governors: userspace, ondemand, and perfromance. Ondemand works fine. Userspace and performance makes extrage things (i tested quickly, to be honest)
I defined several profiles in SetCPU, depending of battery chage, and seems to work fine. But, I did not enable "Set on boot" option in SetCPU and need to activate "Perflock Disabler" in SetcPU menu everytime I reboot Legend (I prefer to test a SetCPU a few days before enabling "Set on boot")
well...this is nice... after disabling the "perflock" option...
I set the minimum value to 19mhz....lol... with "ondemand" management of the cpu...
I think I'have seen a HUGE improvement of the battery...When I mean HUGE, I really mean HUUUUUGE!
Like, for a 12hours use always with 3g data on,and 2 hours of wireless...lost only 30% of battery...
Testing today for more results...
I use the profile manager in SetCpu to set the CPU to 128-256 while screen off, max mhz while charging, etc.
I have seen big improvements.
Yes, battery improvement is very nice. This solution is great.
I am testing a profile to 122-245 while usb charging. So, when I use Googla Mobile Navigation it is able to load a bit battery while using GPS (normaly drains battery a bit while charging)
out of charge at 6am...it's now 10am...3g ON...wireless ON now for 2hours...
So, in resume, on 4 hours of use the battery loss - 6%
At this rate, and with these settings it should last for about 66hours, about 2,7 days.
Let's see...

I can only say...in 3g mode and with the wireless ON 90% of the time from 6am to 00.00, i had more than 40% battery left at 00.00 when i went to bed.For me it's a new record.

In my case, tested yesterday:
Battery consumption:
battery at 100% at 10:00 am. 3g data on 1 minute every 15 minutes (JuiceDefender), 30 mínutes call and 8 emails received and red a long de day. Battery was at 41% at 1:00 am. I spent the day in a place with low 3g network (between 1 and 2 bars in the top right corner)
SetCPU Configuration:
-Profile 1: when battery is between 50% and 100%: min 122 mhz, max 600 mhz
-Profile 2: when battery is between 30% and 50%: min 122 mhz, max 480 mhz
-Profile 3: when battery is between 0% and 30%: min 122 mhz, max 245 mhz
So, battery save is very nice.
this is soooooo interesting....
I couldnt find the app in the market...i found the apk in the HTc Dream forum...version 2.01 by coolbho. Is it ok to use that ?
i think so...
in worst scenario...it won't run lol...(i think!)
If i use linpack i can see someone with a legend that runs on 711mhz? Am i missing something can we overclock..

I've made some profiles too, and it's working really well.
Are you guys using the auto detection of the device? I've used it in the first time, but it detected my device as a Hero(?) since the max frequency was only 528mhz. Then I've changed the device and selected MSM7x27 manually and got the 600mhz max and many middle frequencies like 120, 122 and 128mhz. Now I've changed the device again to auto detection and it worked this time, got the 600mhz max, but less middle frequencies (no 120 or 400mhz). Also, i'm using 122mhz as the minimum frequency in all profiles, isn't 19mhz too low? Or the demand feature really works that well and I will not even notice any difference?
wasup!
19mhz is not too low, i've used it and had a huge increase in battery life.
I am using profiles also at the moment.
Regards

Hi,
You can download from this link:
http://forum.xda-developers.com/showthread.php?t=505419
If you like the app, you can donate getting from Maket. Look for "setcpu for root users". It is only 1.99 USD.
I need suggestions to setup good config in SetCPU i have kyrilos rom 7.5 beta and Galaxy 3 phone of course. thanks
There is option to automatically detect optimized setting.You can create profiles and enable them.Setting speed to powersave mode while charging and while screen off saves lot of battery.You can still experiment and see what suits for you.By the way setting some extreme values might affect life of your phone so be careful.
It is strange but in setcpu on my galaxy 3 conservative mod is not working. So ichoose userspase

Try latest version it works for me.Maybe you can try rebooting phone see if it works then.
Use 400Mhz-800Mhz on demand for battery.
Go to full 1300Mhz for performance but this will drain battery

I have g3mod 2.0 OC kernel
My config its
Main 400-800 Mhz Ondemand Set on boot
Profiles
Temp >45°C 200-500 Mhz priority 100 Ondemand
time 2am-6am 83-83 Mhz priority 95 powesave
screen off 83-500 Mhz priority 90 Ondemand
Battery <20% 200-600 Mhz priority 80 Ondemand
Greetings
Tested on rooted NST with firmware 1.1 and stock kernel.
Simply install SetCPU and set this configuration:
1- go to Main. In scaling select ondemand. Mark set on boot
2- go to advanced. Mark set on boot. Sampling rate=300000, Up Threshold=90, Ignore nice load=0, Powersave bias=300. Apply.
(See attached pictures)
This is the configuration i like, but isn't the one working. You can try new ones.
Underclocking is possible with a free app like CPU tuner (and maybe with other apps, i think), but configuration is a little bit more difficult.
After trhree days of use i can say that really improves battery life.
Enjoy!, and sorry for my bad english.
Has anyone tried this trick?. Works it, really saves battery. Some opinions, please.
I did these settings with SetCPU last night at a full charge, and about 10 minutes later turned off the screen with the battery at 98%, wifi off.
24 hours later, powered on and battery is at 95%.
So I do not see much improvement with battery life during sleep. I'll see how it goes during normal use.

of course you cannot see any difference in deepsleep mode, it changes the cpu behavior while not sleeping (i.e. when you are reading)
by the way, you can also use AnTuTu CPU Master (Free) to do the same for free
Celeborn, I've downloaded Antutu CPU Master. Do you have any recommended setup for this app???
i used the same setup of the [OP] hombretranquilo, it seems to work good
Thanks a lot for the easy settings. I already own SetCPU so it was a piece of cake. Let's see just how effective the app is.
Did anyone tried to underclock it more, to 600 MHz for example?

Hi!
I have a D802 with cyanogenmod 10.2 .Everything is perfect except the cpu controlling. My problem is that when i set a maximum cpu frequency it wont stay there. After a couple of minute the phone override it and change it self.. I have tried setCPU , cpu adjuster and the system default settings. Do you have any suggestion. I would like to underclock my cpu because it generates lot of heat while on heavy load.
Thanks for your aswers!
Sincery,

I am having the same issue. Have you found the solution?
I'm searching for the perfect gaming rom
For me a gaming rom need to have good performance and great battery life.
I tried a lot of rom but didn't find the perfect one.
Please share your experience (rom, kernel, settings) which make you stay with.
Well, I'm using the GPE rom by Danvdh. I'm running the default kernel that comes with the rom (Googy-Max kernel)
It seems to perform pretty well.
I underclocked the CPU to 1242 (1.2 GHz) and it seems to be running GTA San Andreas (on default settings) and The Walking Dead just fine and without any issues like stuttering and slowdowns.
I could get about 2 hours playing those games on battery before the battery dies (But the phone is only a couple of moths old, so the battery isn't worn out). This of course is just an assumption as I generally don't let the phone go below 50% or 20%.
I've disabled the button backlight and vibrations. Set the screen brightness to the lowest setting (adaptive brightness off). Turned off GPS.
Turn off wifi and mobile networks if you want maximum battery while gaming (duh). Heck, you might as well turn off the radio if you want to maximize battery while gaming, (put it in airplane mode) cuz that eats the most juice (aside from the screen).
CPU Governor: Intelliactive
I/O Scheduler: FIOPS
GPU Governor: OnDemand
Every other option in the STweaks app is set to default.
Also, make sure there are only a few background apps running.
