Battery life on this phone is abysmal - on a fresh phone. Didn't restore much from titanium backup.
Would like to drop the CPU down a good 25% or so, can this be done without too much stress? It's an unbranded, rooted i9505 in Australia.
I suspect I'll need to flash something to do so, is that right?

Define "superb" for me.
Apologies for jumping in here. Can you define abysmal too? I would say my battery life is more than double my S2 (that was Cyanogen niggtlies but this is currently djembey's slim). Biggest drain is usually the 3G but I have that off most of the time. It is hard to compare to be fair as we will all use different settings but I have a lot of the bloat removed or disabled, power save on and screen at half brightness. How is yours setup as maybe we can shyc settings a little to compare more closely.

If the reason to underclock is to save more juice, you should understand that the phone doesn't work on 1,9ghz most of the time, on average it's 200-800mhz depending on task, so you would not probably win a lot battery if you underclock let's say to 1.7 unless you're a heavy gamer.

I know this tread is already pretty old, but that answer is only partially true.
On stock configuration the GS4 uses the 'ondemand' cpu gouvernor. That gouvernor ramps up the cpu speed to the max when cpu activity is detected and will then slow down the cpu depending on the task. So everytime you open/close an app the cpu is running at 1.9ghz. (At least that I heard/experienced) using a custom kernel you can choose a different gouvernor which is more battery friendly, or lower the max cpu speed(from 1.9 To for example 1.7ghz). You can also lower the min cpu speed so that when the device is idle, it will consume less power (I think standard is around 350mhz and I put mine on 189). Some kernels even allow to underclock the GPU. Undervolting will also save battery.
In short: using a custom kernel you can really save some battery, increase performance, or get a better balance between the two, but you will have to take the time to find the settings that work best for you. I personally use KT kernel, with an overclocked CPU and GPU, but I also undervolted them both by 75mV, and with some tweaking with settings for when the screen is turned off, my battery lasts longer than stock configuration.
Correct me if I'm wrong on something, I'm not a Cpu expert
And sorry for bad english

Check this out, if you long press the power saving icon in the notification pull down, it will bring the settings for it, Uncheck all but the cpu. It will run no higher than about 1.3 ghz and is plenty fast for all tasks. I use that setting on the s4 and note 3. I never ran into any lag except TouchWhiz home launcher but I use Nova Launcher anyways.
You will see a better battery life as well.

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!

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?

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.

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

Excessive overclocking really did damage your hardware, depends on the quality.. Overclocking from 1.0ghz to 1.5ghz really give a performance boost, in benchmarking.. In real life, only noticeable in process hungry apps, such as 3d games.. Gimmick? Well, if its a gimmick, it won't give any sudden resets or lock ups.. The processor have a safety switch if the temperature increase because of oc'ing.. If it's to hardcore, for example, 1.0Ghz to 1.8Ghz or even 2.0Ghz, for sure you processor will overheat and lock ups.
Well, mine running at 1.5Ghz, no lock ups or whatever..

You will barely notice the difference in most circumstances. Even if your phone runs fine at 1.5 or 1.8 ghz it will probably reduce the life of the chip over a prolonged period.

it will help in cpu intensive tasks, that which require lots of calculations, math stuff, 3d drawing done via cpu, faster cpu, better...
in other tasks, don't even bother, there are lots of other things far slower then cpu.
downside, heating, battery drain, increased rate of damage..!
Im using SetCPU for saving battery life. Set the cpu for 384 while screen is off. Noticed quite a difference.
OP, your asking if a overclocked cpu will give a better performance or if it's a gimmick? Really??
Of course it will give you better performance, that goes without saying but the question is, are you willing to sacrifice battery life? The chip will most probably last for years and years if overclocked but 1 thing that kills chips is heat and volts.
I only overclock when I need to and when I'm done I go back to how it was, usually.
My phone is fast enough at 1GHz, dont need overclocking, all games and apps goes fine fine
Most OC kernals are also undervolted anyway so I wouldn't worry about it
to be honest, i use mine with "underclocked" at 800mhz, trying to get at least a half-hour of battery life... i don't see the point in overclock a 1ghz processor, imo, even with a speed gain, the bad side effects easily override the good ones...

I'd look at other reasons for your battery life, if it's really that bad.
I'm running at just a touch above 1GHz with no side affects what so ever and get 24+hrs with heavy use, 30+hrs with moderate use and 40+hrs with light use, and that's never turning wifi / 3G off unless I'm in bed when I switch to 2G.
At 1GHz the OCUV kernal I have installed uses less voltage than stock kernal at stock speeds so in theory it's actually safer.
It's not that bad, but it's not so great as yours too. I got about 16hrs with 'hard' use, what is enought most time, but sometimes i get in home with the blinking orange led. Quite annoying...
I try my best to improve the battery life, but i was becoming a battery freak, or something like that, always checking currentwidget...
I get 3 or 4ma at stand by, what is considered normal, i guess... and always use full brightness, hate to use anything bellow...

From what I understanb, the A500 and other mobile devices are under-clocked at the factory to save on battery. The allows you to adjust the CPU up to 1Ghz. So, not really overclocking, but you will see a big difference.

just so you know this app is not needed for our CPU to run at the full 1ghz. the CPU runs full speed when the system demands it by default. this app is more for setting profiles to extend battery life. if you use system panel or a similar app you will see that the CPU runs full speed when needed. CPU tuner seems to be a great app for extending battery life though, so thanks for the tip.

Wrong. None of the devices are "under clocked" at the factory. There is just no reason that your device needs to run at 100% speed 24/7, so the CPU and the OS scale the speed back if the device is idle. Just like a laptop or desktop PC.
so if honeycomb automatically scales back the CPU when its not need does that mean that this kind of app is really needed to save battery?
Sorry, I must have miss-read something some place and was understanding it incorrectly. All I know, is thing are running faster.

Depending on your preference. One thing this app will do is scale down your frequency according to the profile you select ,for example, if your battery is at 50% and you want it to last longer, than what it would at stock settings, you can create a profile for your CPU to run at a lower speed like 800mhz. That way your battery will last longer throughout the day if you can not charge it. You can set multiple profiles for different battery levels of your preference and have the cpu run at slower speeds to preserve battery. So if your anal about your battery state then it can be very useful. Becuase at stock settings the sytem will run at whatever the speed is demanded by the system. Whether it be the minimum or maximum processor speed.
I usually prefer performance over battery life myself so unless I am going on a long road trip or I am out camping I would not use it as I have no need, but every one is different.
Very general question. I'm on 2.3.4 4.5.91. unlocked rooted. cam Does anyone use setcpu or JD on this release. It seems as if settings has some battery controls in it. Just curious. Thanks

If you are overclocking, SETCPU allows you to control clock speeds with profiles and set lower CPU operating voltages to save battery.
See here for some undervolting info:
http://forum.xda-developers.com/showthread.php?t=1183059
I have not found any software like JD that works on gb.
forgive the noob question, but what is JD?
i use SetCPU, bought it off the market (gotta support our devs, right?) and i'm LOVING it. it does everything i need for managing my CPU, i have custom profiles setup for all sorts of situations, and undervolting gives me amazing battery life. when i'm running Ninja SF, i can use my phone for 25-30 hours without charging (moderate use, no hardcore gaming or music)
but on CM7, i can unfortunately only average about 20-25 hours of battery life with the same use.
JD = Juice Defender

Hmmm ok. I'm on stock not over clocked. Setup may not do much for me. Juice Defender could control the radios. But settings seem to have some battery options for extending battery life.
I didn't know if setup since I am rooted would at least help with scaling and throttling down processor speed when battery reached certain levels. I'm sure these would help on a custom Rom.

I'm wondering what is the battery life difference between 1000MHz (as max) and overclocked 1400MHz?
In most [low-end] phones little OC consumes a lot of power, but I don't see this issue in SGS.
Are you using your phone overclocked? How long last your battery?

I dont know why would you do that... I use SGS in max 800mhz(underclocked) and its perfectly fast... But regarding your question, prolly would be about a day and a half of battery with those settings on OC.

i cant see how it shouldnt impact battery.
