Now that we have root, what's everyone's favorite root apps and things to do with root?
I don't do much with root myself, but I do use Titanium Backup and SetCPU.
What do you guys use?
I'm using SetCPU but I'm trying to determine whether the clock speeds actually change on the stock kernel. Seems to be working for me, can anyone confirm?
titanium backup, root explorer, voltage control, adaway for me.
Titanium Backup, Root Explorer, Root Call Blocker, Adblock.

We almost definitely cannot overclock with the default kernel. At least that's how all devices have operated in the past. I doubt HTC would ever include that function on the kernel, as it can damage devices.
Underclocking might work though, and I'm pretty sure changing the governor would work.
To test it, run some CPU benchmarks while using various settings. If it's working, you should see a noticeable difference in your results.

I will do this now.
Not planning on overclocking at all! I never overclock phones, only underclock to improve battery life. I'm using the 'powersave' governor but it doesn't seem to be functioning correctly. Will post screens soon.

This kernel module allows you to run any stock HTC Froyo kernel with lowered CPU voltages. Reducing voltage decreases power consumption by the CPU, thus lowering heat and increasing battery life.
INSTALL:
You need root or an unrestricted recovery image (e.g ClockworkMod) to install this. The default settings decrease voltage by 75-100 mV which seems stable on my device (HTC Desire) and is reported to be fine on the EVO. Just download the attached file and select it from recovery or ROM Manager.
I've built "update.zip" files for the EVO 4G with Linux kernel versions 2.6.32.15-g746f4f0, 2.6.32.15-ge2fb08e, and 2.6.32.15-g59b9e50. You can check your kernel version in Settings->About phone->Software information.
Other HTC devices running Froyo are supported. If you have a different device, please give me the full version number and I can add an update.zip for it.
Full details and source are in the original thread in the Desire forum:
[KERNEL] Undervolt driver for the stock HTC kernel for Desire and others (2.6.32.15)
Update, 2010-11-22: Added driver for 2.6.32.15-ge2fb08e.
Update, 2010-11-23: Added driver for 2.6.32.15-g59b9e50.

Sounds like it would go well with Fresh's new rom.

Too weak... funny considering there is more work involved in setting this up than most linux guys even do on a pc... let alone a phone.

Maybe not. I run the netarchy kernel but don't OC because it seems to crash at random times. I use it because the battery life is better than stock.
I'll revert to a clean back-up and give this a try just for giggles.
I would like to see some results.
I say that because I have tried a few havs roms and get worse battery life.
I think what a lot of people don't realize unless they are heavily into overocking is that microadjustments just dont have much effect there needs to be some substantial drops to really have any effect on battery and heat.
I realize that this is no desktop or laptop cpu, and that this cpu is based off such low voltages but such minor voltage adjustments, 80-100mv just arent going to have the desired effect unless that equates to a "substantial" voltage drop.
Not to mention the fact that most of you are going to overclock your phone without the faintest idea that doing so, even with a lower cpu voltage, will still cause worse battery life. This is a fact.. to argue it is futile. Its the nature of the beast.. do some reading and find out for yourself.
You can overcome some things by using on demand overclocking but you have to do extensive testing to find the sweet spot.

Nice work. I'm not interested in oc'ing, nor flashing a custom kernel. I may give this a go after a few others check in w/ results. I just want to know that it's stable.
I went to your other thread and saw the source. Clever solution, nice work. I really do like that you wrote a device to /proc that does a little more than report the frequencies back. This will make it very easy to write some scripts, or even a UI, that lets me tweak the settings. Hopefully I have some time to work on that in the upcoming weekends.
Will take a look at this first chance I get. Trying to finish my battery logger since everything available now doesn't log exactly what I want to know. Kudos.
Does this make HAVS obsolete ?

Undervolting meaning only when screens off or on and off ?
I installed and will get the best battery life yet. Better than when I was with King and other kernels....thanks!!!
Anyone have any results from flashing this yet? How is battery life? Any stability issues?

No stability issues and it seems to help on battery a little bit but I really can't tell a big deference. I was expecting for it to help out more. Thanks anyways OP for the share
i did say those little microvoltages aint gunna make any difference.
plus if you try to overclock you just cancelled any lowered voltages and actually cause higher power draw than stock mhz at stock voltages.
higher mhz equals higher power draw whether you have it undervolted or not.
you have to make a signifigant drop in voltage to make any difference at all. let alone if you try and overclock.
not trying to dog the guy who discovered this i am just sing plain and simple math, heat, and electronic voltages.

This isn't a kernel its just a couple of files that go with the kernel. One file for initial boot ect/initd and a .ko file that goes in system/lib/module folder.
I have an Evo, [email protected] #11. I would like to try it. Please build an update.zip to support it.

Hello,
I am running stock ROM with S-oFF and rooted. Ive got setCPU running via the methods used for temp root. (Basically pulled the code from the BAT files everyone used to overclock and temp root). It works alright, but after a reboot, I have to redo it.
I see people are running ROMs that include setCPU. How does a custom ROM manage to keep setCPU "set" after a reboot? Can the methods be used for the stock ROMers?
Also, I see that setCPU requests SU hundreds of times a day when I look at the SuperUser logs. Why is this? Is it bad?
Thanks,
Matt
They are using custom kernels and oc daemon.

thank you for the reply! Is this something that a stock rom could implement in its own? Or, should I consider flashing a custom rom?
Thanks,

Its a little hit and miss right now unfortunately. The kernels can still be buggy on some devices, though they, in theory, should work on a stock device. If you have issues you can always just flash the stock kernel back. Some love it and have no issues, others not so much. In fact some devs have stopped bundling their kernels with their roms and leave them as optional add ons because of issues.
Is cm7 expected do implement overclocking? If so, I may just wait for them to finish.
Matt
Not sure...they are playing cm7 for the sensation very close to the chest, lol, but I don't think so. Just a guess though.

Ahh...I guess that only time will tell what sort of advancements come in the way of overclocking (reliably and efficiently).
My theory is that setCPU is the cause for my headaches and may be the cause of most others using it as well. (Crappy battery despite conservative governors as well as phone freezes and data connectivity issues). Seeing setCPU request SU a few thousand times a day seems suspicious. I have it frozen for now, well see how things go.
Matt
I don't know for sure either, but I suspect you might be right, at least to an extent.
With the stock rom on a rooted MT4GS, can SetCPU be used either to underclock or overclock? Or both?
And if so, what would be safe settings to use?
You can certainly underclock (or at least try) with setCPU; however, overclock cannot yet be achieved since HTC hasn't released the kernel source code yet so none of that can be manipulated.

Great, thank you!
I've used SetCPU with the stock ROM because sometimes the max speed is set to 972MHz instead of the maximum 1188MHz. One problem though is that I get those 'SetCPU has been granted superuser permissions' every few minutes. Is the OS killing SetCPU or trying to prevent any changes to the clock speed?
Interesting...I haven't had that problem.

Hello all, i rooted my tab today. Installed Superuser, Set CPU and Titanium backup. I froze a few of the pre loaded Samsung apps that came with the Tab. What other things can i do to speed up performance now that i am rooted? Any suggestions?? Thanks!
(Also if anyone else is currently using Set CPU on their Tab7 +, what settings work well for you? )

Which model? (There are at least 4 different ones.) Are you willing to give up battery life for that speed? What do you want to use your tablet for?

I have the Wi-Fi_GT-P6210. I guess my main issue with Set CPU is what are the limits i can go to without locking up the device. I have Set Cpu on my EVO 4g so i am familiar with it. I guess i was just seeing what advantages rooting gives me. I have my EVO rooted so i know the benefits on my phone, but what about the TAB. What apps can i remove without effecting performance. Thanks
If you want to overclock or undervolt, you'll need a custom kernel (see my sig.) At that point, you can OC to 1.4GHz. (I didn't include support for 1.6GHz has the processor in my own 7+ wouldn't stay stable at that speed, so I can't test it properly - it was also extremely easy for me to only add 1.4.) For voltages, you are also kind of going to have to experiment. I'm stable with 1300/1225/1125/1025/950/900 on my tab plus, but I can go much lower on my SGSII (which has the same processor.) You can search on the SGH-i9100 and SGH-i777 subforums for what other people have done with voltages.
As for which apps can be safely frozen, there's a post or two on that from a couple months back... I'd suggest searching for the full list. Nearly anything that looks like bloat really is.
I'd never suggest actually removing stuff - much better to just freeze it... then if you figure out that you really needed it, it's trivial to defrost it.
Good luck

I have a couple of question/advices I want to receive an answer for about CPU.
So I am struggling to get better battery life without hurting performance.
1) Can CPU apps hurt battery life by themselfs. I mean could only using an app not regarding the settings damage the battery life. Is it better to let the cpu work by itself and not any apps managing it?
2) Which is the best CPU control app?
3) Will Underclocking improve my battery life a lot and will it make performance worse. What are the best settings to keep battery life and performance optimized at the same time. If I want to play heavy games I will overclock for the time I play the game. But I don't want my cpu to be working at 1600ghz for instance when I am not doing gaming or similar heavy processes. What are the best settings to improve battery life but not hurt performance?
If you use an app like SetCPU, you can have profiles. I used to have it so that the phone would underclock when the battery reached a certain % or was too hot.
If you're S-Off and rooted, you can get way better battery life if you flash a new kernel. I'm using Faux v004, I've set SetCPU off and just let the kernel do its thing, and my battery life is at 1 day and almost 15 hours.
(I also play a lot of games and the Faux kernel is very resposnive. My games load much faster that they did on stock kernel)
Thanks! I am using this Kernel http://forum.xda-developers.com/showthread.php?t=1216197 and I find it good. I am rooted and used SetCPU in the past so I know all about profiles and etc. But my questions were. Do programs like SetCPU drain battery? And which best CPU program? And what about undervolting?

Apps like that don't really have any more of a drain than checking your email or receiving a text. If using Faux Kernel, there's an app out there designed for it that helps with clocking and undervolting it, made by the man himself. If not, AnTuTu has one on the market, I think.

Fauxclock hasn't been updated in ages and it's by Romanbb, not faux, afaik.
As for the OP's questions:
1. Not really. I haven't noticed any extra battery drain with CPU apps so it's probably not significant.
2. I don't think there's a 'best' CPU app. I used to use SystemTuner, which worked fine for me, but I switched to SetCPU because I wanted to underclock the intellidemand governor on faux's latest beta.
3. Underclocking will lead to some improvement in battery life. As for undervolting, some people say it helps, others say it's a placebo; personally I've never bothered with it. You could try using faux's kernel with the intellidemand governor, which sets the clock speed (and whether the second core is online/offline) depending on the CPU load. As for best settings, it depends on each individual kernel and your own personal needs, so you might want to try flashing a few custom kernels to decide which one is for you.
