Hey,
So I'm on the fence about perma rooting and over clocking my G2, but i have a few questions:
1) Will my battery life suffer greatly due to over clocking say to 1Ghz or 1.4Ghz?
2) Are there any real world noticeable real world performance gains besides benchmark scores?
3) Will perma-Rooting it decrease performance? (Back when i had the mytouch 3g, the phone never felt as snappy after i rooted and installed custom roms, as compared to stock).
Thanks
1) battery life is the same if not better when overclocked with setcpu in ondemand mode at 245/1100mhz
2) there is a definite performance increase
3) custom roms can decrease performance depending on the rom and ui (sense is a bit heavy). Just simply rooting will not decrease performance. Also, CM6.1 is super snappy, especially using Launcher42
DO IT!

Launcher42? that's a heck lot of upgrade from Launcher2 I'd like to check it out
but he's right overclocking is not going to eat up your battery much. Heavy graphic ROMs do however suck up battery and performance. I personally like to stick to rooted stock roms and tune up here and there to fit my personal needs.
You should however read carefully and make sure to understand every steps you're doing if you want to root your phone.

Alright I'm going to give it a shot later tonight probably, i forgot about the SETCPU profiles where you can have the phone under clocked while the screen is off. That should definitely give me better battery life. Ill be back to post results

Good luck and I'm sure you will enjoy your G2.
Oh, and don't forget to show it off to your friends. Let them see how this thing "Fly"
I oc to 1.4+ with setcpu and a few profiles set up i get much better bat life then stock. Im also running a sense rom which feels sluggish until you oc. At 1.4 it runs smooth as can be with live wallpapers plus all the pretty sense animations. The only problem i have is i hate the sense dialer and msg system also i want to change the "personalise" tab....do people really change theyre settings everyday that they need a dedicated button for it? Anyway i digress

No, that's not entirely true BUT with SetCPU you can profile it with different mode which can benefit the battery life.

I don't notice any difference in battery and I have the 1.9ghz kernel. I normally keep it at 1ghz though. I enjoy it overclocked. My games run incredibly smooth, when navigating my phone it literally almost feels like it knows what i'm pressing a split second before i do and benchmarks rape the face off anyone else I know with an android phone. It's just sooo smooth. It really boils down to being the kind of person who likes to hold a powerhouse of a phone in the palm of their hand. (Literally) with even just the 1.4ghz OC you'll never have to ask yourself "can my phone run this without being sluggish?" because the answer is yes, it can probably even run two or three instances of whatever made you question yourself in the first place without being sluggish. Any if you're worried about custom roms from the past, just remember how outdated your old android is compared to this one. No offense because I can relate, I used to have a G1 that is now a hand-me-down to my brother and whenever he asks me to mod something on it, I'm just amazed at how slow it is and really don't know how I tolerated it for the last 2 years. I mean I'd score a 150 quadrant on the G1 (on a good day) but with my full OC on, the G2 scores 3000~3100. That's roughly 20 times faster...
Bottom line is that you won't need to worry about "will this make my device sluggish?" for quite some time.
Hey
Alright guys i got the phone perma rooted now, but i havent installed an OC kernel yet, two questions.
-Which kernal should i install if i want 1.4Ghz? there seems to be two threads with 1.4ghz kernels
-Do i need to install Bacon Bits for the kernel?

just install cm6.1 and setCPU and you will be fine, then you can tweak it up to 1.42 if you like or whatever you want it at
Any heat related issues? Let's say I get into a zone and play some graphics intensive game 6 hours straight on USB power at 1.4Ghz? Wouldn't that put out more heat then the G2 was design to handle possibly shortening its life span?

It doesn't. However, overclocking is misnomer. What we really mean is over and UNDER clocking. For example with SetCPU is can create a profile that greatly slows down my CPU when the screen is off. This saves the battery a lot, since my screen is nearly always off.
Also, I can create profiles that slow down the CPU as the battery lowers in order to offset the fact that I overclock the CPU when the battery is fuller.

Probably could shorten the life span. I keep phones for a year or two, though, and shortened life span for me isn't an issue. The phone becomes outdated before the CPU gives up.

I've gone a full 10 hours with my battery still reporting 100%.

my default sense rom does not feel sluggish at all.
this oc is not really required from my point of view. and it also does not increase battery. the thing what increased is the underclocking when screen is off.
and this you can do even without overclocking. and THEN it brings even more gain.
an example of "real world" for me is how well my g2 plays PSX games on the emulator. I have it overclocked at 1.5 on setcpu and it runs chrono cross pretty much flawlessly with no noticeable slow down.
i use setcpu for underclocking since i don't do enough just yet to overclock, i haven't noticed any battery increase just yet and i've been using it for a few days now. i almost questioned my self if i was losing battery life due to my system mhz always fluctuating? is this a possibility? i just added a profile for screen off 245/245 but i still had to choose on demand? what should i put there. thanks for ur help everyone
I installed the bacon bits 1.4ghz kernel and setup some setcpu profiles.....battery life is much better now.

screen off profile doesn't work with G2
noone has any proof it does change anything.
with or without widget running
Ok so I have searched all over the forums and through google to find an answer to this and I can't any where so here goes. I am currently running the syndicate rom with the extreme kernal installed and when I go to use set cpu I have it set to conservative but any time I try to limit the cpu speed with the sliders it doesn't tae effect. The green numbers above the sliders will change stating my preferences but the white numbers that show the actual speed of the processor will continue to climb past my desired bottleneck. It looks like thecpu always stays between a range of 200 mhz and 1.2 ghz no matter what I set it at. If I change the style to something other than conservative it will change the behavior like performance will keep it at 1.2 or what I select and battery saver will keep it at the minimum. On demand and interactive seem to respond as well but are a little buggy and any little touch on the screen will make the processor jump straight to the maximum and stay there fr a bit which I would assume would kill my battery quite a bit faster. Does any one know if this is an issue with the phone, rom, kernal and if there is maybe a better settng than conservative or a different kernal I could use I was looking into the phoenix or fluff kernal. Any help or recomendations would begreatly appreciated. Thanks

Its been a long time since Ive used it (2.2.1 scales pretty good) if I remeber right,interactive is what you want to select,but on some kernels conservtive is what you want to select.I never used the profiles,I think they dont work all the time.
That's odd I never had that problem with syndicate. And I know for sure that almost every overclocking kernel recommends conservative, for some reason the other profiles can cause problems. There's a couple things that I've learned.
Conservative, for one thing, is never going to be an on demand setting. Typically it will just up the cpu to the max you set it at whenever there is some sort of activity on the phone. Which begs the question, what do you have the max set at? if its 1ghz, remember that the kernel is overclocked, so a setting of 1ghz will allow you to go to 1.2ghz. (I'm almost positive you don't want to set it at 1.2, because then it will peak higher than that) I think the max you set it to should be the listed physical limit of the processor (ours is 1ghz obviously), and the overclocking handles it from there (at least that's been my experience).
Also, remember that when there is no activity (your phones in your pocket), the cpu will be at your minimum. So you save battery in that regard, because with out setting cpu limits, like if you're running stock, I think it might run at the max all the time. (I don't that for a fact tho) again, we pretty much have to run conservative, (I've read its something to do with these hummingbirds and setcpu and overclock widget aren't built fot them) so its an all or nothing deal, you can't get "just enough" processor setting.
Try creating different conditions to help yourself out. When I had syndiccate I had a different setting for the screen being off, for being plugged in to a wall, for being plugged in to a computer, and for being below a certain battery %. Those are really cool features and help out a lot.
And as far as other roms...I use baked snack right now with his ultimate kernel. Its only sllliggghttly less stable than syndicate (but most most most defintly stable enough for a daily driver), and I get much better battery life and performance. He recommends using overclock widget, which isn't as flexible as setcpu, but defintly gets the job done. You'll have to google baked snack and find his website since they kicked him off of here.
Hope that helps, let me know if I didn't quite answer your question correctly.
Sent from my baked and emotionless SPH-D700
From my experience,you need to set it to 1.2 to activate OC...That being said,there are some kernels that need the interactive setting to work right...and 2.2.1 scales to the lowest setting when screen off even without setcpu,thats why I dont use it anymore.I will again once we have an official OC kernel for 2.2.1.

I actually used to have bakedsnacks rom and I liked it but it became a bit glitchy on me but I did think the battery life was a bit better. I only am using eclair as I want to wait for a final build of froyo to come out from sprint so the developers can utilize it better. I tried some of the leaked ones but I prefered the 2.1 better, all of the 2.2 ones were missing minor things that I used so I switched back. Also interactive setting just keeps the processor at max clock for a really long time before it scales back down and I didn't like that. Has anyone used the fluff ondemand kernal that is supposed to be for bettery battery life with syndicated 2.1? So I have deleted setcpu but it seemed to eat my battery faster so I put it back on. Maybe I will try some other kernal configurations since I was told that I can swap kernals without looseing data.

Fluff was glitchy for me,I liked Xtreme kernel the best.
For those of you on CM7 (preferably RC2 or later nightlies), are you using SetCPU or the built in CMSettings CPU manager? Which is giving you better performance/battery life?
I can't help but think that the built in CM Settings CPU tuner is going to be conflicting with my SetCPU profiles.
Been using nightlies since #30 or so, and I currently run SetCPU with a normal profile, a screen off profile, and a profile for <10% battery and haven't touched CMSettings' CPU manager.
I'm contemplating just uninstalling SetCPU for a day or two and seeing what a 1017max / 245min Ondemand or Powersave governor via CMSettings ends up doing to my battery life considering there will be no screen off profile.
Any thoughts?
I dumped setCPU after a lot of testing (and even bought it on market)
I'm finding I'm much happier using inbuilt CPU settings. I think battery life is the same but performance is better due to the fact that SetCPU would sometimes get stuck in my screen-off profile when turned on causing the phone to be really slow.
I recomend uninstalling setCPU, set your ONDEMAND governor with ~1Ghz and run it... You'll find your battery about the same but much less hassle.
I have yet to try that, I somewhat feel obligated to use SetCPU since I purchased it lol. But it probably won't be the last time I waste money at the market.
Neither. CPU tuner works best for me.

I've been wondering about this too. I don't quite understand how it works. Can I just set the frequency higher till a certain point without changing the voltage and get the same battery life?
What's the best way of doing this? Just change the clock speed or do I need to change something else or update the kernel?
Whatever you tell SetCPU to do, you'll see the same settings mirrored in the CM settings.
I say setCPU cuz as battery gets lower... I have my CPU speed lower also. Basically, 15% battery lasts me forever :] lol

Definitely. This is the one thing I like about SetCPU is having the 10% and 5% profiles so that I can get the last few % to last forever if I need it. Although in normal day-to-day use I'm never pushing it below 20%.

Yea I see this, as far as the governor changing etc.. This is why I'm wondering if it would be easier on my phone to just run only the CM Settings one.
I notice that every 5th or so time I unlock the phone, there is an obvious lag switching from the screen off profile, and my unlock sliders jitter around and it takes 4-5 tries to unlock the phone. I think this is probably partially due to both settings switching over trying to change.
I think I might try backing up and uninstalling SetCPU for tomorrow to see how it goes.

I've read on here that overclocking the Vision's CPU up to 1 GHz requires no over-volting, and in theory should not affect battery life (but not sure exactly where that information originates from). But there has been lots of debate on these forums on whether the SetCPU app helps or hurts battery life depending on screen-off profiles (underclocking to save battery) or its constant polling of the CPU clock (possibly killing the battery faster).
A kernel that supports overclocking is already part of the CM ROM. If you are on CM, you can just adjust the clock speed under Settings>CM Settings>Performance>CPU settings. Or set the CPU clock using an app like SetCPU. Choosing one method over the other is what is being asked/debated here. If you are on the stock ROM, you need to be rooted, flash a custom kernel that supports overclocking, then install an app such as SetCPU or CPU Tuner to set the CPU clock to your liking.

I'm not sure about CM's kernel with the over-volting but I do know that Pershoots kernel can be overclocked to 979mhz without over-volting (Pershoot told me himself).

Well obviously.... But why the hell would you ever need to be running at 1.8ghz? The fact that you are always using a temp-specific profile method should show you that consistent 1.8ghz isn't good for the phone...
Okay so I uninstalled SetCPU last night and I'm going to run just the CM Settings CPU manager all day to see how it goes. Running like this:
ONDEMAND governor
Min CPU: 245 mhz
Max CPU: 1017 mhz
On nightly #19 also.
Okay so its midnight almost, and I'm at 13hrs unplugged and 52% battery still. Pretty general/light use, phone is just as snappy and the lack of a screen off profile doesn't seem to effect battery at all. Liking it so far! very interesting to see the screen off profile not mattering much.
SetCPU for me. I like to have a temperature and charging profile, to prevent the phone from overheating. Even at 1ghz the possibility exists, nice to have a backup incase.
I'm thinking set cpu conflicting with the cm built in caused my ****ty running problems. I have not used setcpu since and been good so far

With multiple tries... If you change the settings on one, it cancels the settings on the other... Maybe it's because you had set on boot enabled on both?
im going to run the CM tuner and uninstall Setcpu and see how it runs. i never thought about this but i do get that lag when i turn my screen on sometimes. im gonna miss having the profiles but ill see how it runs over the coarse of a couple days.
Hey there, I just a few days ago rooted and flashed the Syndicate Frozen rom and am not getting such good battery life...
I was wondering how big of a difference SetCpu makes on battery life/performance in general? With moderate/heavy use (internet browsing, facebook, email, txt messaging) how much should it improve battery life? am getting around 10hours at the moment with moderately light use... Is there any free alternative app that runs comparatively well?
I guess what I'm really asking is: is it worth it to buy setcpu, and will it make a dramatic difference on my battery life? This Rom is supposed to improve battery life, and I think I read is overclocked to 1.2... Will setcpu let me set this underclocked to 1,0 and then like 800 with screen off, 600 idle? Am new to the android thing [have had my EPIC only around 2 weeks today]
Thanks for any help!
Overclock widget does pretty much the same thing, and you're going to want to set something like
20mhz min 1 or 1.2ghz max
Then 100mhz min 400mhz max for screen off.
You can set the speed to.anything you want. If you want battery to be the best then.set it to 100/1000 on demand. If you emwant performance then 100/1200. Also I don't set profiles cause I was reading somewhere that they aren't good to use on any galaxy phone.

Nice info read up on it and yes you can set it anyway you want like stated above. I bought mine from the market to support the dev for the hard work involved in making setcpu, dont know if you know but it is free for xda members just search for setcpu. It is only $2.00 well worth the price so please support the dev if you can.

Don't expect it to magically give you another 4 hours up time. 1 extra hour would be high hopes.
I use SetCPU with the CPU set to 200/1000 and ondemand, and the battery life has improved GREATLY, well worth the $2 to support the Dev, IMO, even though XDA members get it free.
I've abandoned SetCPU and uninstalled it. Unnecessary consumption of system resources.
Same with any other user-space app/widget to control CPU speed scaling.
In the Bonsai ROM, the exact same capability, sans the profiles which I (and most people) don't use anyway, can be achieved by setting clock range and governor in /etc/init.d/24-cpufreq script. I expect that all the other OC kernels, if not every custom kernel, has a similar way to set CPU clock governor.
I have mine set to 100/1200 on demand, and it works well for the demands I put on it. Way low consumption at idle, but when I need something it instantly responds.
I routinely get 16-18 hours off the charger, and put it back on the charger with sometimes as much as 40% remaining, but as always YMMV. A lot of it has to do with the ROM, but I'd say that CPU scaling has realized a tangible gain for me.

Talking about Bonsai ROM tweaks on a Syndicate thread would be like me talking about BMW mods on a Honda forum. Either way, I looked around in the system folders and I can't find the 24-cpu file you're talking about. I upgraded yestereday from the 2.1 SyndicateROM to this, and for the first few hours, the ROM itself was definately quicker...I don't know if that's just because I came from 2.1 to 2.2, not to mention all the other 2.2 tweaks. After a few hours, I completely forgot that I could overclock this to 1.2Ghz. Installing SetCPU and bumping it to 1.2Ghz felt like just another jump. System resource consumption aside, it makes the phone all that much quicker while going between screen, apps list, closing apps, etc.
I could care less about battery life because I've learned to always have a charger around me since my days of the Moment, of hell, even my Treo's. I want fast, SetCPU is something I can see the difference in just from turning it on and off and seeing the differences.
I'm running Bionix V 1.3.2 with the Immortality 2.1 kernel.
What I'm curious about is everyone's preferred overclocking app?
From what it looks like, it comes down to SetCPU, No-frills, Tegrak, or CPU tuner.
No frills advertises doing the overclocking without running in the background- which is appealing.
What are your thoughts?
Im not familiar with anything other then set cpu. I like it because I set up profiles for charging, screen off and temp. Ive used it for a while even when not overclocking, just for the screen off profile.
go with set CPU that's great the profiles really help save battery

You can use Voltage Control to OC too...
Sent from my XDA app cuz I'm stalking your mom....
So it looks like there are a couple of categories the overclocking apps can be divided in to- those with profile management and without, and those for the SGS only.
Profile Management: SetCPU ($1.95), Tegrak ($1.95), CPU Tuner (Free)
Without: No Frills (Free), Voltage Control (Free/$3.84)
Both Tegrak and Voltage Control are specific to the SGS family- why would I want to buy a program that only works with specific phones when I can get a solution that will work with all my future phones?
I know SetCPU is the most commonly used solution, but I keep reading so many complaints in the forums. Does anyone have any experience with CPU tuner in comparison to the others? I'll at least tinker with it when I have time since I'll have more than 15 minutes to see if I like it.
Set cpu is horrible, atleast from my experience.
Constant screen of death, meaning after I lock phone,it won't turn on until reboot.
Instability. Lagged my phone even with oc only up to 1.2
Voltage control is what I prefer.

Well I'm using voltage control right now because its tailored to the hummingbird and I like the undervolt settings. Once you find the right voltages, your battery will be (more) amazing.
However, I've used setcpu since I've had my htc hero and it works wonders...at first when the galaxy s came out, there were conflicts and setcpu couldn't tune the hummingbird(atleast for the Epic 4g, the Galaxy S for Sprint), but that's since been worked on.
Setcpu is very straightforward. When you start it up, just tap autodetect speeds and it'll have a slider for min/max and yyou just slide it to the appropriate speeds. Then you use "governors" that dictate how the processor clocks...for example, on "conservative" the cpu scales up to the speed it needs to process what you're doing and slows down really fast when not in use. "Ondemand" is basically the same thing, but it scales high up and then lowers itself to the needed speed. "Performance" keeps your cpu clocked at its highest speed and keeps it there. Its good to run performance when you need to run benchmarks or do a lot of stuff on your phone at once, because it kills the battery faster (obviously)
Just try em out...setcpu is free on xda, just look for it in the apps section on android general I think or the g1 boards
Voltage control, be wary about, because if you mess with the ettings and don't know what you're doing, it'll corrupt your phone.

I like voltage control too and pimp my CPU mainly because SetCpu hardly ever supports the kernels I use and when it does it gives me reboots
Thank you, I'll give Voltage Control a try. Do you have any 'safe' recommended voltage settings when using smartass, and then I'll see the limits of my phone from there?
No sorry idk about the vibrant, but it sould be able to handle the uv since we're both hummingbird
When you use VC, do it one clock speed at a time. The voltage slider moves in -25mV increments. Each processor is different. For example, my phone can handle 1.4ghz unervolted by -50mV but if I put it down one more notch, my phone freezes and its FC galore. So its good to have a backup.
If you're not turned away by the amount of time it takes to tune VC, then it'll be worth it. You just have to thoroughly test the phone each time you undervolt to make sure its stable before you set it as Boot. To test just scroll around and run acouple of benchmarks.
For example, when I started my UV, I started with 1.4ghz and worked my way down to 1.3, 1.2, 1.1, 1.0, .8 and .6 ghz. Slide it to 1400MHz and then slide the voltage bar one notch to the left to uv it by 25mV. Hit apply and then run smartbench, quadrant, neocore, linpack, w/e just to make sure your phone can handle it. If it can, move it one more notch and test it out. Rinse repeat for the rest
Setcpu is way more user friendly and does what its supposed to, but vc is for power users I guess

If I do recall you could also change the voltages in setcpu. Ya know if your kernel supports it.
