A few weeks ago when I still had my HTC Hero it was overclocked to 672Mhz (standard = 528Mhz). It gave me a little boost in performance on Froyo, also the batterylife wasn't decreased too much.
But with our N1 running on 1Ghz, will it give much difference when clocked to 1113/1152Mhz? And what about batterylife?
If SetCPU is used what are your settings then? Mine is currently running on stock speed, no SetCPU.

I have my nexus one rooted and flashed to MIUI Rom and clock @ 690mhz I get way better battery power. Before I would only get 6hr to 8hr if lucky now I get from 9hr to 13hr depending how much I use it.
set to 1.13 ghz
then screen off to minimum 245mhz

So you underclocked it, what about the speed? It's not to laggy?
Nexus one can run reasonably smooth @ 600mhz and above. It might not open applications as fast as it will be @ 1GHz though.
i think 1Ghz is enough for n1
why do u want an overclock?

I didn't said I want an overclock. It's allready very fast on 1Ghz (compared to my old Hero ), just wanted to know your thoughts about overclocking the N1.
im overclocked at 1152 mhz and profiles set for 245 max with screen off. Overclocking is nice because i like the snappiness but most people cant tell the difference between 998 mhz and 1152. its not needed to overclock but i think profiles help alot. just my two cents
Ok thx, I will try 1150Mhz and see (if it's stable and) what batterylife does. I'm also going to try underclocking.
I have my N1 only for a couple of weeks now and I must say, this phone is awesome. It's VERY fast compared to my old Hero. I remember when I was installing apps on my Hero it became very slow and couldn't do anything untill installing was finished. With the N1 you still can do things while installing apps without lag. The responsiveness and smoothness is also a lot faster. I loved my Hero Because it never let me down, ok it was all a bit slower, but it was getting there. Now with the release of Gingerbread (custom ROM) it became to slow for me and that's why I sold my Hero and bought the N1. It was very difficult to find one, because of the EOL (end of life). But eventually I found one and i'm very happy with it. The N1 is allready more 1 year old, but it still competes with the best phones out there.
I generally run overclocked at 1075MHz, which gives a good balance between battery power usage and processor power. My understanding is that a different voltage scaling method is generally used above 1075MHz, so power consumption will increase above that point.
Didn't knew the voltage would increase above 1075Mhz, will keep that in mind

This is, of course, dependent upon how the kernel is constructed, but this is what I have generally found to be true.
Give us some feedback
I overclocked it too 1075Mhz when screen is on (screen off 245Mhz). Will give my thoughts in a day or 2.
Just report that my battery drain is almost the same as on stock settings. I think it drains a tiny bit faster on 1075Mhz, but nothing major. On the other hand, I don't feel it's faster on 1075Mhz then on stock speed. Only benchmarks give me performance increase.
I'm now on CM6.1.1 with stock kernel (cyanogen), I tried other kernels like Wilmonks kernel,.. Although it was more responsive, battery was going down even faster. I get best battery results with stock kernel.
Hard to choose
more speed = more battery drain
less speed = longer battery
I think I stay with the last option (less speed = longer battery), because Wildmonks kernel doesn't give me enough performance increase over the stock kernel on stock speed.
I have mine at 998mhz, but overclocked 1152 while plugged into power.
Either way, its so easy to play with the clock settings, i'd just have a play with a bunch of different settings if i were you.

You can use SetCPU to create profiles based on different circumstances.
Me, I have mine clocked to a max of 1075 and min of 245 with the screen on, 576 max / 128 min screen off, 998/128 charging (to reduce heat - overclocking while power is applied can make it silly hot), and a failsafe to clock down to 576/128 if the temperature gets over 50*C.
Fabulous app.
Correct me if I am wrong. When you use setcpu to "ondemand", the CPU speed can ramp up to max whenever necessary, otherwise the speed will tune down to min especially in standby mode. In that way, you can enjoy the advantages of overclocking and underclocking the CPU speed i.e. increasing performance when needed and saving power when not in use, right? When I loaded Rod's MIUI and Wildmonk's kernel, I can underclock down to 128Mhz and overclock up to 1.152Ghz. At the end of the day, I still have over 60% of power left after not so heavily use (some web browsing, checking email and listen some music). Overall, setcpu is a great app for me.

This is probably a stupid question but I'll ask it anyway. I've noticed my phone draining lately (or maybe it's not, I'm not quite sure what the battery life used to be xD), and I recently overclocked my phone to 1.25 GHz (my profile on SetCPU is ondemand), does overclocking affect the battery that much?
I run Froyo (rooted with wifi fix and the 1.25 GHz kernal)
I'm using an ultra low voltage kernal at 1ghz and haven't noticed a difference, if anything it seems like it's better.
I guess it probably largely depends on what kernal.
I've been overclocked for 4+ months. The first month before I rooted, I was getting around 16-18 hours on a full charge at the stock 550 speed. After I rooted, a lot depended on the rom (lesser so) and the kernel (more so). I think the best performance I got was on ChevyNo1's SS rom (2.1) with one of his kernels ... 40+ hours overclocked conservatively at 800. My first shot some time back with CyanogenMod got me 3 hours with the early Bekit kernels but the past several versions up through 5.0.8 I was getting about 30 hours clocked at 800 with a jdlfg kernel. Now on Froyo I'm getting close to 30 hours again conservatively at 800-1000 ... which on a 2.2. rom is more like 1200+ since its faster.
So, in short, my battery life has significantly improved while running faster than stock. But no 2 Droids are identical in terms of how a rom and/or kernel perform. With 2.1 roms my Droid seems to like jdlfg's kernels, while on 2.2 the P3droid kernels do good. But that's what I found out via a lot of trial and error, not anyone's post saying "You must try ______'s kernel (or rom) as its da bomb!"
I would like to include that the post above by "cvhovey" provides some valuable information that might interest you and suggest anyone untreated in this thread to read that post.
Using an application like SetCPU you can throttle down the processor speed when the screen is off, this reducing heat and gaining better battery life. This doesn't mean you will get better battery life if you use your phone all day and never turn the screen off. But is totally worth it because u feel like I'm getting awesome battery life, plus an amazingly fast phone because SetCPU will overall me to my personal preference of 1100mhz on demand.
The answer to your actual question depends on how well you set up your phone preferences according to what benefits you the most, and what method of adjusting processor speed. I only mentioned one here, there are mire ways than just an APK.

1+ on that. But how one uses SetCPU can also make big differences, such as which governor is selected. SetCPU at 400-1250 with the Performance governor will essentially run at its highest speed all of the time (if I'm correct), whereas with the Conservative governor will ramp up from 400 to 1250 at a slower pace, or at a faster face with Ondemand.
This thread can give you some helpful tips: Battery Saving Techniques - Theories in Test
Alright, thank you for your help ^^
i used SetCPU and my phone had continuously reboots...
I just had to uninstall it..
Were you using profiles in any way? A specific ROM? I've had similar a experience with certain ROMs (specifically UltimateDroid).
Best guess is that it just didn't play nice with the modded kernel.

Hey all,
My phone is rooted. I'm wondering how Overclocking might effect battery life. Better? Worse?
Also, what is a solid speed to OC on the Captivate?
It will be worse, but if you do UV it will last a bit longer...
Battery life will go down, but its by such a small amount, you wont even notice it(depending on how much you OC it)
and stable OC values will be different for every phone since all processors are not made equal. For example, my max stable overclock is at 1.2ghz, but my friend was stable at 1.4 with undervolting by 100.
You really just need to play around with it and find what works for you.
If you really want a solid stable number, im pretty sure every captivate I've seen can go up to atleast 1.2 ghz.

That is very untrue. I read an article (for the life of me can't find it) that overclocking is actually better for battery life. I have in fact had better results on my LG Optimus V with overclocking at 806mHz (highest stable clock setting) than with 600mHz (standard). LeslieAnn (Harmonia dev) linked to the aforementioned article in one of her posts. If I find the link I will post it.
I've only OC a couple of times but 1200Mhz should be stable for the majority of phones out there. The most I've got out of my phone was 1440Mhz on MIUI with Glitch kernel, while my friend was able to hit 1600Mhz with same rom and kernel. It took me quite a bit to figure out what voltages for what steps etc to get it to work well so if you do not feel like tinkering with it for a long while I wouldn't try to push your OC too high.
Battery life doesn't usually decrease unless you over volt. That being said most Galaxy S will get 1.2ghz-1.3ghz on stock voltage. Usually a good idea to undervolt most "steps" except the high clocks (1ghz+) but this varies on phone, rom, kernel, etc.

ohh... i thought that said undervolt... but over clocking as well will make it decrease some.
If you ran faster you would burn more energy in the same amount of time. (over clocking)
If you reduced the weight of your legs or gravity you would burn less energy. (under volting).
Most people dont notice battery drain when overclocked because the processor speed doesnt run full speed all the time. it governs to different speeds for what it needs to do.
go stock speed and play a game till it drops to a percentage.
recharge
overclock with NO undervolting and play the game again till the same percentage.
less time. guaranteed.
just sitting at the homescreen and flipping through your app drawer and using face book wont kick your phone into high gear, with stock or overclocking. you will never notice.

I have my phone and nook's clocking speed set at the same for min/max settings. I play a mean game of RUA and AirAttack HD. I've in fact timed my battery life on standard clock settings and my overclocking. While overclocked, my nook lasted 10 minutes longer than at standard speeds (while playing AirAttack HD, which has intense 3D graphics). And you might suggest I undervolted, but I never touch that stuff. My volting stays where it is.
Cyanogen 8? Is this next? Or is this in the works? Also is 2.3.5 next and would it be numbered a different version when Ice Cream comes out? Also is anything coming from the devs to overclock to 800 yet?

It's been done. So very very few phones are even stable at 800, and those that could generally performed worse in benches at 800 than at lower clocks. Many of these devices bootloop above 700.
Cyanogen 8 will not come out yet since will most likely be ice cream sandwich. I am not even sure is 2.3.5 will even come out and no the devs can not overclock this device to 800mhz because is 768 is the limit of the processor. Most people's phones do not even run that smoothly at 768 anyways. If somehow the dev found a way to overclock it to 800 (impossible btw but this is just a what if kind of statement) since the processor can not handle 800 it would just overheat the thing and cause crashes.
Also, on a side note, this should not be in the Development section. This should be in general or Q&A
This belongs in Q&A for future reference.
CM8 will be next, obviously. It will be based on Ice Cream Sandwich, so no, it won't be in development until ICS is released to AOSP so that the CM team can start using that code. 2.3.5 is an update coming out soon for the Nexus S 4G that fixes wifi and network speed, as well as adding more secure NFC for Google Wallet. It won't really affect us when it is merged into CM7. ICS is expected to be Android 4.0, but it could be 3.5 if Google decides.
There is a kernel that goes over 800Mhz, but anything over 768Mhz can be unstable on some phones. I tried it and there were no real performance gains, but battery life was a lot worse. Performance was actually worse at the highest CPU clock, in my experience. Just stick with 768Mhz. It's stable and chances are that you can get even better performance at a lower clock. I get better battery and performance at 633Mhz. It all depends on each unique phone.

I can confirm that the Godmode kernel was able to push some phones, such as mine, past 800Mhz. Although I had a faster processor speed, my battery would drain incredibly fast as well as overheat. Even though I never hit a bootloop with the kernel, the battery life, overheating, and loss of performance kept me away. Sacrificing too much for having a faster processor speed. Normally I overclock to about 729Mhz and have great battery life, speed and performance in conjunction with a min of 19Mhz and a smartass governor.

Yup, I'm at 806 - 19 ondemand while posting this and I can already feel it slowing down a little. 729 - 19 on demand is my best setup. I've tested a lot with trying higher setups than that but so far 729 seems to be the best for battery life and performance on every rom I've ever tried

i bought mine at radio shack back in september and it was still on 1.5 and ive never been able to get over 768mhz without it freezing and bootlooping its different with every hero.
i stay at 352-691 ondemand and thats plenty fast for me
Mine was running 1.5 also and it will run fine at 768 but battery life suffers so I usually run at 352/710 and battery and performance are good (depends on rom kernel)

Hey rubyknight,
just wondering why 19? Ive seen people do that but can the processor really ever do anything at 19? if so, doesnt it affect stuff like wake. Im trying it now just to see for myself. Ive been playing with a really high min value between 480 and 576 with the high at 748 and it actually doesnt only seems to affect battery life a little, both on the .29 and .35 kernels on jaybobs roms and on OMFGB.
Thanks

Just the slightest UI lag... this is on jaybobs 7/8 with the .29 kernel, with background data off. And my regular usage which is not a lot. but for me its good. i wish I had tried it ages ago.

Hello
I recently acquired a nook color and i am going to install cynogen mod 7.1 and google apps from clock work recovery method, but i want to overclcok to 1.2 or 1.3 ghz, i understand that cynogen mod has an overclock facility built in, the part i am not sure about is to reach 1.2 ghz or 1.3 ghz do i have to use dalingrin overclock kernel to achieve these speeds, or is it possible in cynogen mod 7.1 without the kernel.
Any info would be appreciated.

Dal's kernel has been included in there for a while now. If you use 7.1 stable to later nighlies you are definitely safe.
ok, thats great, thanks for the reply, appreciated.

It appears the GPU may run best at 1200, even thou the CPU can do up to 1300.
It certainly seems to be true that going past 1200 can slow down graphic intensive operations. I am guessing that's probably because the graphics processor has to run at a ratio of the CPU and going past 1200 ends up with a lower graphics frequency.
But depending on the type of applications used there can be benefit in going higher and most Nooks seem to be capable of 1350. This can be seen in two different benchmarks. Quadrant gives significantly higher scores at 1350 than 1200 whilst the graphically more intensive Nenamark is slower at 1350 then 1200.
I ended up using 1200 anyway as it feels fast and probably also helps with battery life.
Check the voltage settings as well as these can normally be lowered a bit to help again with battery life. I use the one's originally quoted by Dal and don't have any stability issues. ( 09.25 / 1.05 / 1.2 / 1.275 / 1.325)
I did a comparison of 1200 and 1350 MHz with the Sunspider JavaScript bench. 1350 is faster but frankly I have a hard time telling the difference between even stock clock and 1350 in actual practical usage.
The most obvious speed boost I've found is running 16bit color. Big difference in browser scrolling performance.

I have run at 1200 / 1350 for the last 4 months and it has been stable and I have not seen any real detectable difference in battery performance or in how warm the device gets. The governor means that a lot of the time the Nook is running at lower clock speed anyway.
I don't recollect seeing any reports of damage on this forum to the Nook through over-clocking. Increasing voltages from the stock values on the other hand is probably not a good idea. There may possibly be longer term effects from overclocking but I'd guess the effect on lifetime is small enough that most people will have changed their device before it is significant.

A lot of people say that overclocking the Nexus 4 is useless as it's so fast to begin with, but that turns out to be false, yes, it's useless for making e.g. games run smoother, as they all already do, but it's very useful for reducing loading times, and it turns out that the % of time saved is close to the % of increased clock speed.
My setup: Nexus 4, franco.Kernel updater v9.3.3, Franco Kernel #666, Jelly Bean 4.2.2 JDQ39, Governor Interactive. Angry pigs HD 1.1.0 app loading. Fresh reboot for each speed. I did three measurements for each clock speed and left voltages at Franco's defaults. I would suggest looking into the undervolting threads to figure out how low you can go with voltages, undervolting is good underclocking is usually not.
1026 Mhz 1025mV default Franco
15.4s
15.9s
15.7s
1512 MHz 1150 mV default Franco
11.5s
11.3s
11.3s
1620 MHz 1175mV default Franco
11.1s
10.6s
10.6s
1674 MHz 1175mV default Franco
10.3s
10.6s
10.7s
1728 MHz 1200mV default Franco
10.5s
10.3s
10.3s
Conclusion
12.5% faster clock speed = 8.85% faster load time, which means increasing clock speed is 70% effective at reducing load time going from 1512 Mhz and upwards.
40% faster clock speed = 35% faster load time, meaning that people who think running their device at 1026 Mhz is as good as 1512 Mhz are wrong. Nearly doubling clock speed nearly halfens load time.
The reduction in loading time is reduced a bit as you reach higher frequencies, but it's still 70% effective so every extra Mhz helps cut down the wait. Overclocking the Nexus 4 is meaningless in terms of increasing smoothness IN APP, but meaningful in reducing load times significantly and in increasing the responsiveness of your system.
please tell me for saving the battery and still maintaining a little smoothness

my brother uses a galaxy s3, and after using it for a few months he tried my n4... he was amused how fast things open and how smooth everything was, and it was all stock frequencies. i think it makes no sense overclocking this beast, it is already fast enough. +/- a few seconds doesnt make that much of a difference but drains the battery significantly more. just sayin'.

Sorry but little OC can help you save more battery in day to day usage. (If you are not playing only games on your phone).

not according to my experiences, and i did play with oc/uc and voltage quite a bit. i always ended up going back to stock on the n4 (not on my old motodefy though) because of the drainage.
So, a 50% increase in clock cycles pushes the performance by a bit.
Who would've thought...?
well that's normal, overclocking = more power draining, more speed; just like with CPU or ram on pc, no rocket science here.

OC? Don't you mean Downclocking or Undervolting?

Nope , also OC can (in theory) improve battery life because the CPU finishes its task faster.

But er... Wouldn't it would theoretically need more power and therefore generating more heat than stock frequencies which in turn will have a negative effect on battery life?

It REALLY depends. I'd say most day-to-day usage, an overclock can actually help save battery by 'racing' to sleep (hurry up, finish, drop to deep sleep on cpu AND radio). I think being on 3g makes it even more pronounced because you're letting the radio drop back down to a lower power state as well as the CPU. So if you need to quickly open an email attachment, and cpu is the limiter, it can help it finish, get off the network, and back to idle state faster and save some battery. Now if you go on running benchmarks instead where you just keep throwing more work at it that's a seriously different story. There is also a point of diminishing returns (usually 1 or 2 steps before the absolute limit, in our case about 1670mhz) but in general, a moderate overclock can help.

I agree with u, but remember its a theory.. U finish faster so the time it uses more power is less....
^^Look at the post above me, he got a good example^^
The best of both worlds (if your phone is capable to do this) is when u UV and OC. U would use less power on a higher frequency. Win-win in theory.
But I know what u mean and its hard to believe, but I think that's what @alan1901 wanted to say.

If you are lucky, you can overclock using STOCK voltage for the maximum clock.
IE, i see many undervolting their phones by alot. I would just try 1150mV (default voltage for 1.5ghz) for your highest speed (OC as high as you can with this voltage), which means you are not using more power, but still making your phone faster.
Haven't tried on mine, but say 1.6-1.7ghz should be possible with 1150mV for a few at least.
No, 50% OC is not = 50% reduced load time
Let me summarize:
OVERCLOCKING > UNDERCLOCKING FOR THE AVERAGE (POWER) USER
You load a lot of apps, you don't play games or watch videos for hours, productivity is your focus. Depending on use you could save probably 1 - 6 hours a year (see assumptions below). Battery gains won't be significant, but spending less time with the LCD/Wifi etc on could give you some gains as the CPU is one of the lower power drain components.
UNDERCLOCKING > OVERCLOCKING FOR THE 3D GAMER
You spent a lot of time playing CPU intensive games, keeping the CPU cores at max clock speed for extended periods of time. In that case you could get some battery life gains at the cost of responsiveness and app loading times - your call.
IN MORE DETAIL
-------------------------------------------------------------------------------------
UNDERCLOCKING + UNDERVOLTING PROs/CONs
+ Reduces CPU temperature, if that matters to you.
+ IF keeping the CPU at max clock speed for extended periods of time, a lower max voltage could give you enough extra battery life to negate the time lost waiting for apps to load - your call.
- Increased load times - even on the Nexus 4 a lot of apps take > 10 seconds to launch, and don't forget in-app load times, reboots etc.
- No significant battery saving in most cases, potential for loss (if doing a lot of app loading you could even get worse battery life as the screen, wifi etc has to stay on for longer, and the screen is the main battery drain).
- Time spent finding stable voltages.
OVERCLOCKING PROs and CONs
+ Potential small battery life gain, as your device spends less time with the screen/wifi etc ON.
++ SAVES YOU TIME. I'm estimating 1 - 5 hours a year depending on usage.
- Times spent finding stable voltages and clock speeds.
-/- Apps does not RUN smoother.
Why 50% CPU does not = 50% reduced load time and why you test things
---------------------------------------------------------------------------------------------------------------------
It'd be more like 40-30% depending on relative clock speed. I did a simple test as we did NOT know that app loading was mainly CPU limited, could have been memory. And If load times didn't go down there wouldn't be ANY reason to OC and underclocking would be a good idea.
Assumptions behind an estimated 1 - 6 hours saved a year by overclocking
---------------------------------------------------------------------------------------------------------------------
Say that you're on average waiting 4 minutes a day waiting for apps to load, rebooting your phone, waiting for web pages to load, waiting for in-app content to load etc.
Overclocking can cut down that wait time up to 10%, that's nearly 1/2 a minute saved every day, 3 1/2 minutes a week, 3 hours a year. This means you can get a good return on the time it took you to overclock your device, assuming you'll keep it for a couple of years. So if that's the case, why not do it? You'll save some time and you'll enjoy using your device a bit more.
Currently I'm OCd at max 1674 Mhz @ 1225mV, otherwise using default Franco voltages and interactive governor. Stable and very snappy Might be able to reduce voltage and retain stability but this is fine.

I said little OC. Example. Stock cpu clock is 1000mhz and 1000mv. Now, you OC your phone to 1200,1300mhz without changing voltage, or by increasing it a little bit(+25, +50mv, to make phone stable), it will use higher cpu frequency with the same voltage like on lower frequency or with a little higher voltage. So it would finish tasks faster, going to idle faster without getting any heat and give you more battery. On my nexus s and galaxy s3, galaxy s2, i tested it, and it helped (about 30min more screen on time for me). But if you play games a lot and doing some heavy tasks then underclock and undervolt are best for you. But on that beast of phone, i woldnt underclock it beyond 1.2, 1.3, not sure what frequencies are there. If you UC that phone a lot, you can easyly go with some weaker phone.

is there any kernel that can overclock with 4.3?
