[Q] Real world noticeable benefits of Over clocking G2?

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

Excuse me, since when does increasing the clockspeed of your CPU INCREASE battery life?!

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.

^This.
I've gone a full 10 hours with my battery still reporting 100%.
Sent from my HTC Vision using XDA App

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.

SetCPU app and it's effectiveness? Syndicate Frozen ROM

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.

20Mhz would freeze the phone. :O
I personally like running it @ 100 Mhz when screen is off and 1Ghz when screen is on.

I am pretty sure XOBX meant 200, cause your right 20 is pretty much crawling...

Yep, I meant 200, the damn autocorrect kept changing mhz to Hz and I must've clicked backspace one too many times.

Thanks, so it would make a big difference in battery life?

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.

Please share your voltage and governor

Please share
1. your favorite governor (do you use any different governor on different profiles?)
2. your voltage parameters
3. Your benchmark using quadrant
Thanks

No one wants to play?

Maybe like me, they have no idea what you are talking about
What is a governor?
What voltage do you mean?
My quadrant score is 3900 ish

Thanks for the reply, I don't think I'm good enough to explain but, in a nutshell,
A governor is a a piece of code in the kernel that decides on the cpu speed. each kernel has multiple governors
voltage is where you can decide what voltage is delivered to your cpu at certain frequency. undervoltage will usually help you save battery. we have to pay attention not to go too low or it phone will freeze
download setcpu it will all become clearer

I will give this another bump before letting it die

Even I would be intrested in sharing this
currently I am using CF root with ondemand and its working all good

FM kernel with interactive. I find my phone snappier with this governor. I liked it the most with smartassv2 on Abysssomething (don't remember now) kernel, but too many teething problems with this one, had to revert to FM. I'll give it another shot soon though.

Have you tried InteractiveX? Or, better yet, know the differences between the two? I am currently using smartassv2, FM kernel and have no complaints but would be interested if there was something a bit snappier when opening an app (I still get a bit of lag if I quickly select an app after unlocking the phone).

Yes, I've tried InteractiveX and OndemandX - they're both absolute rubbish (at least from my point of view). Both responsiveness and benchmark results were dismal (2800-3300 quadrant advanced). These are governors for anally retentive battery life lovers. Nothing wrong with that itself but beats the purpose when buying state of the art top shelf performance smartphone IMO.

Good to know. I appreciate the advice. Does that mean you also tried smartassv2 with the FM kernel? Any discernible difference between that and interactive, if you have? And sorry for all the questions but it saves me the trouble of trying them!

I just flashed the 1.3 FM a moment ago. Now running 100-1704 smartassv2, haven't played with voltages yet. Responsiveness in terms of screen scolling, lags & stutters seems better than 200-1400 interactive. Performance in Quadrant Advanced and Nenamark2 seems a tiny bit worse (but I don't really care about that, I use benchmarks only to roughly estimate, smoothness is what I'm after). I can't give you direct sources because I don't remember, but having spent several hours digging last weekend I concluded that for people who put performance slighly over battery life governors to be considered are interactive, smartass(v2), savagedzed and performance. Funny enough - I'm getting consistently worse benchmarks on performance governor on all kernels. I wonder why?

Thanks again. I will play around with some of the governors and settings to find the right fit. I think I will try savagedzen next but I am pretty happy with smartassv2 and may just stick with it.

Smartassv2 and vr. After reading a bit about it they seem to be the best for performance and balanced battery life.

i share with you my SetCPU config, voltage ...
it's very stable for me. It's not performance oriented but battery friendly.
what you think ?
EDIT : I use AbyssNote Kernel 1.2

I'm getting nice results here on FM Kernel 1.3. 1704mHz (1375mV) - 100mHz (775mV), lulzactive governor. 5000-5872 in Quadrant advanced, 32-35 in Nenamark2. Battery life good with low to med usage, poor when playing games, running satnav etc. - hardly a surprise We'll see about stability but so far so good.

This thread is finally picking off ! thank you all
I am currently on FM 1.3 and preferring lulzactive
I don't use any over clocking I guess I don't dare. is it safe?
I think i'm pretty aggressive with under voltage i'm running 1175mv at 1400mhz and 775mv at 200mhz. For some reason my phone freezes any time I use the 100mhz no matter the voltage .
Can you share the whole voltage for a comparison ?
with all this I can hardly get a full day of use with my battery but I guess I'm a pretty heavy on usage. no gaming or anything extensive but wifi-browsing-emails-3g-bluetooth all day

I read on some other kernel thread that Samsung's implementation of the 100mhz step is incomplete/buggy. That's probably why it doesn't work properly.

Is Super Performance Phone Really Important ?

As we can see in many forums, people like to overclock their phone to increase It's performance although overclock can increase battery live and may broke their phone. I think the increased performance can only be felt through benchmark software. The effect on the apps is almost negligible specially on high end phone (like our Note). Why do you overclock your phone and use overclock on daily usage (I understand if the reason of overclocking phone is for satisfaction) ?

Never saw the slightest reason to overclock my phone.

Emulators and because I cannot resist getting extra performance. My captivate was a beast OCed.
Some people don't get it others do...like everything in life. Some don't get how we can live with a phone this big but we do...
Sent from my GT-N7000 using XDA

On GB (LC2) I overclocked to 1.6gHz and it made everything run smoother (screen transitions, opening and closing apps etc.
On ICS I haven't felt the need to OC. It runs super smooth and fast as it is.
But maybe I'll get bored some time in the future and do it just for something to do...

I'm on stock GB LC1 CF rooted and I OC to 1.55.
Differences when I open apps. They open faster. And not that huge battery life drain because cpu stays at 1.55 a little time and for me the faster app opening matters
*only 2% at 1.55 (not even 1h from 40) - with CpuSpy

Its not bout whether its "important" or not... Its more like, If you can...then why not!? I did overclock my sgnote till 1.6ghz at 1.7 it would reboot.

Its like gettin more for less
Just as Overclock with your desktop, some take a step further by changing heatsink, better ventilation, water cooling, etc.

Exactly, its just free power and if you are not dumb, you are not going to kill anything. This is not the dark ages of overclocking and those fears people seem to still carry from those times.
Take for example on GB running 1.6Ghz Nenamark2 scores me about 34fps or so..Damn close to my record with the Captivate which is 33.5! Then I ran 400Mhz on the GPU and boom..53fps...that is some kick ass gains there. While I will probably run 300Mhz mostly, if I find a game that needs the extra performance, I know I have it there so why not use it.

Very true.
On my desktop I have an Intel i5 2500k (original 3300 MHz) OC to 4500 for daily use and when needed 5 GHz.
From 1 year and a half the CPU runs like this and never had any stability issue. And my PC kinda stays on A LOT.
So yes, we don't live in the dark ages of overclocking. Why people STILL HAVE FEAR OF OC!?
These days OC is very easy. Most of the times you can't broke a device / component from OC, because the "drivers" of some microcontrollers from your motherboard won't let you (a lot of protection these days )

Indeed. Plus if you are too afraid then dont push higher voltage, just OC with stock voltage as much as your CPU can do.

Overclocking and underclocking suggestions

The first thing that comes to our mind is overclocking for a better performance and underclocking for better battery life.
I tell you what, you might get bettery battery life by underclocking. But a big problem starts here:crying:,
The processors are tested vigorously and out of the box you get the sweet frequency.
UNDERCLOCKING: Sweet frequency for DEEP SLEEP is 200MHZ.
If you think you can get a better battery life by making it sleep in 100MHZ your are completely wrong, It takes more voltage operating at 100MHZ and thus further drain.
Overclocking: Don't do it, Games like Real racing 3, NFS most wanted plays without a lag, The MALI-400 and Dual core CPU does a great job. So u really don't need overclocking.
CPU GOVERNERS: Don't try switching between CPU Governor's often. By default it comes with ONDEMAND and that is good enough for multi tasking and it is good as a daily driver. ONDEMANDX is a slightly better one. Both of does a pretty good job. So i suggest you stick with these two if you want the phone to working like a S2:good:
Hit the thanks button if you like my suggestion :good:
