hey guys i install custom karnel on my xpera mini...now i can overclock up to 2 ghz..i just wanted to know pros and cons of overclocking..
pros- increased speed and less lagging,
cons- short battery time, increased temprature.
Is it possible to underclock it to get more battery or shelf life from the phone?
we can overclock and underclock if we install custom karnel..

Yeah. Root your phone, and install SetCpu, and you can Underclock freely and thus save lots of battery

Overclock will give you temporary boosts and lets you to showoff, and to get super high benchmark scores , but its not for regular use
Overclocking reduces battery performance and increases heating of device, which might cause your device to get unstable
and of course high temp = bad for the hardware so be careful
My SE mini works very well at 1610 Mhz.No crash,no instability but I use high frequency for max 2-3 hours or when I want to play without lagging
Pros
Immensely fast speed
Massive score on Quadrant
No lag or crashes
Cons
Battery life goes down fast
Phone temp goes up - Massive problem
Phone might get bricked if the phone gets unstable (Happened to my friend)
I only overclock my phone whenever I play games or need to switch between apps constantly. Though I always keep on 1024 as that is the default setting
Recently I overclocked to 2ghz was chkin stability and gosh I burned my battery, its workin but fone keeps restarting n I had to buy new one!! Dis is d con
Pro: faster n better performance!!
Overclock can cuz serious damage too!! But its fine to showoff a lil but in controlled envionment for a short tym!

Overclocking is not actually advisable because there are chances that it will affect your phone and might screw it up in the long run .
Battery drain is inevitable and you will experience it .
Phone will heat up
It may not be good for the other internal components because of the over heat-unlike computers a mobile is not actually equipped with much of cooling system.
There is a good reason why the manufacturer has set a clock speed ,otherwise isn't it better for them to just overclock a phone and sell it for a higher price ?
People who design the custom kernels are just telling the maximum possible value they could overclock to.
Pros-
Bigger numbers
Little more faster performance
it recommended to not overclock always..just overclock when you really need it..
What are peoples thoughts on a modest overclock to bring me back up to the performance I am used to?
Say taking an ACTIVE up to 1300 or so.
With these new NON-OC kernels, are they undervolted? I have seen claims of absolutely massive battery life and I'm reasonably sure some of those were using cpu throttling and an overclock.
So confused at this point. Also heard some of the newer ACTIVE handsets cannot even be rooted.

As in most things if you not overdo it you can enjoy the benefits of better performance without risking your phone.My xperia mini is running up to 1200 (1024 stock). Also minimum speed 122 instead of 245.So better performance when you need it and lower consumption when phone is sleeping.Overall i got the same battery life, 2-3 days as with stock rom.The best thing to do is get an app that lets you make profiles.Like when screen is off min cpu 122 - max cpu 384 etc...
I don't know about these new kernels you're talking about but cpu throttling is something stock kernels do also (if by cpu throttling you mean cpu speed adjustment)

I installed the webtop over hdmi mod on my Atrix and while testing it out, it got very warm in my hand. I opened the setcpu app and noticed that while overclocked to 1.3GHz, the CPU was running at 75C! I lowered it back down to the stock 1GHz and the temp slowly went down and settled at 63C.
It seems that while in webtop mode, the CPU is taxed at 100% all the time so I'm wondering if it's safe to stay overclocked when using webtop.
Everyone has different opinions of what is too hot around here.
IMO the cooler the better. IMI No Atrix should have a temp above 60c and I'm not even comfortable with above 50c either...

I have experienced the same problem and worried that something may fry.... I have had mine overclocked at 1.45 using debian linux and all of a suddent he phone freezes and restarts.... Since it did it to me the second time I have kept my phone at 1Ghz... I am new at this so please don't beat me up too bad for being a noob... Just want to see if maybe undervolting it a little might help or hurt it?
Thanks in advance
Here are some tips I can offer
1.Try re-flashing your custom kernel and see if that fixes the web-top thing and over heating
Whenever the phone is plugged to the web-top it will naturally overheat so it's kinda expected remember now it's gotta work harder since its displaying on lap-dock or TV,but if you can cook an egg on it it might be too hot...lol
2.Set profile for temperature on setcpu so this way once you reach for example 100F your phone will clock down a little and so it might help the heat issue.You can set even more than one temp profile so this way when it reaches 96 it goes down a little then when it reaches 100 it will clock down a little more and such.
3.If that doesn't help,which in my situation it did.Flash a different kernel mayb it's just the one you're using that is causing funny stuff to happen.
Edit: not sure but i think undervolting helps battery but causes more heat,I myself don't undervolt I just created litterally a bunch of setcpu profiles for battery level,screen off,incall,charging,temp,and time and I'm getting 13 hour days at 1.3Ghz and temp profiles have been helping by clocking down when it's too hot therefore saving battery and drastic overheating.I dontlike my phone going anything over 104F it gets me paranoid,but that's just me.
I tried reflashing the kernel but it didn't change anything. I'm using Faux's 1.3GHz overclock kernel for Gingerbread (2.6.32.9). Is there something else I should be using?

Do what sktrix said in rest of his post.
I use the stopgap 1.0GHz kernel, and UV does lower temperatures. I would definitely try UV'ing a wee bit. You don't need to go crazy. I am using the following with great results for both temp and battery life:
-50
-50
-75
-75
-75
-100
-100
My setcpu profile clocks it back if I reach 60C, (I idle in the low to mid 30's). Under heavy load I reach around 52C max which is quite acceptable.
Now, granted I am not using Webtop, but the end result for UV should be the same. Lower temps and better battery life. You may also want to try just using 1.0GHz when on Webtop. The phone has more than enough power at this clock speed.
There is a bug with faux's kernel that causes the webtop to clock the phone at max speeds until restart.

I know I'm straying from my correct forums here, however I have an LG Optimus 2X which like the Atrix, is a Tegra 2 CPU.
Our phones get VERY hot, I have had my CPU up to 86C before I decided to back off the stress test. CPUs are very good at handling high temperatures, and IMO you will see no ill effects from doing so, I am unsure of whether or not the Tegra 2 has thermal throttling/shut down, but in my experience they should be fine to around 80C.
The only issue I can forsee is the battery, batteries HATE high temperatures and it is awful for their life span, this is why your laptop batteries turn to crap after 1-2 years, even if low charge cycles, because they are always hot.
I would not be concerned about anything in the 70C realm, at all.

Experienced this countless times. More with the latest 1.45Ghz, but it did happen on the previous release. When I dopped the mhz with setcpu, it wont scale but stay at max cpu. It even did it a few times without using the webtop.

So which overclocked kernel is best for webtop? I too have noticed where the CPU hangs at 100% at 1.45Ghz for a while when disconnected but it is always there when im in webtop mode.... How is Faux 1.3Ghz kernel with webtop?

It will still hang at 1.3ghz, though it's a known bug. I just stick with the 1.0 enhanced, there's no noticeable real-world difference from going over 1.0ghz anyway, it's just a benchmark gimmick. Right now, the software that's out there is optimized to run on existing hardware w/o overclocks. I've run Shadowgun at 1.45ghz and didn't see any difference over the 1.0 enhanced.
Now, if we were trying to run games that were coded specifically or faster-paced chipsets then we'd need overclocking to catch up much like you would in the PC arena. That, however, is not happening in the cell phone market just yet.

You will see a lot more optimization than just upping the clock speed. One of the reasons the 1.0GHz kernel works much better than the stock kernel. Also, the ability to undervolt saving battery life.
IMO there is no need for 1.3GHz or 1.45GHz in everyday use of a phone. The only benefit is for OC'ing bragging rights. Until we can control phone temperatures better, it's pointless to risk the substantial heat increase on ALL internal components for extended periods of time which results from much increased CPU temperatures.

I see... guess that explains why the phone doesn't really feel any faster when it's overclocked. I'll flash the 1GHz kernel then.
Thanks for the info.
Not sure if this is the same with phones but normally a CPU should stay at 40C idle and 50C load. Maximum would be 60C while benching or something.
If it goes above that I would definitely underclock/undervolt.

Just curious is most people who root/use custom ROMs overclock, and if so, what settings do you typically use in SetCPU?
I'm using a S2, rooted with latest Unnamed ROM and find myself contemplating if I should make any changes with SetCPU. Lots of options, and Unnamed has all the different governor options, etc. just really looking for some best practices that people who overclock often.
Would appreciate seeing what you consider to be stable overclock options that give a good boost without causing excessive heat/stability issues.
I'm coming at SetCPU with limited experience so I do appreciate any tips that might see rudimentary, or if there are better resources that teach about this I'd appreciate any links as would like to get a better technical understanding of all this. Thanks in advance.
I use No Frills CPU, and I just set it to 1.6 max/ondemand. Absolutely no heat issues or stability issues, so I just stuck with it. Battery life is good.
most maybe but only by a little bit. a good number of people underclock and undervolt their devices to try and get better battery life. to be honest, the newer phones dont need overclocking to handle the current apps and stuff. the older phones like the nexus one and older need overclocking tho. i leave my gs2 stock. what we really need is dual core support before OC becomes worth it on my phone. ymmv
I have never overclocked mine, phone runs smooth as butter at 1.2 so I don't see the need to go farther. Plus I like my battery lasting more than 24 hours...
I overclock my s2. im running unamed 1.3.0. I like run different speeds at different at different battery percents. 1.6 till 75% 1.4 till 50% 1.2 till 25% 1000 till 15% 800mhz till dead. i had some problems with 1.4 ghz but i tweeked the voltage and that did solved my problem. I'm at 50% battery with normal usage. display 1hr 25mn phone calls for 47min and android os for 56min. my phone doesn't get any hotter then it did before i overclocked. I just did it to say i did. It will prolly help a little unless you like emulators then it will help alot. i have to overclock my iconia a500 to 1.6 if i want to play n64 games.
I'm on UnNamed 1.3.1 with the latest entropy dd kernel and am very happy with the stock CPU speed

Opinions from people who really know? I can't imagine that overclocking increases battery life.
It doesn't. At least from my understanding. In fact as I understand it running at higher clock speeds would decrease your battery life no? I usually under clock, so...

The theory is that overclocking allows you to complete processes quicker, which in turn allows the processor to go back to a idle/deep sleep faster. In practice it doesn't really work that way though.

doesn't the increase in voltage also come into effect?
They did talk a little about undervolting to increase battery life. Personally I don't worry about it. I'm not using my phone to sort out heavy algorithims at the moment, so running how it does is fast enough for what I use it at. Just found the article interesting.

They say the undervolting on lower clocks should balance out the higher voltage on overclocks.

Undervolting rarely makes a difference on mobile SoC's, but on the desktop/laptop CPUs you can really save a ton of power with undervolting and underclocking.
Why to overclock and understand it?
Here is a good reason to know what you are doing..
and the battery avg's lasting at least through the day, but most of the time, I have a charger near me...

The article says its not the actual overclocking that is saving battery life. When you put SetCPU on your phone not only can you overlock but you can underclock and set different voltages. I'm not 100% sure how the voltages play into it but you can set the processor to run at really low speeds during certain acts ei. when the screen is off, or any other time you don't necessarily need alot of power. That's and I changed all the voltages (I got them from a post where the guy knew what he was doing and tested them). I get almost 2 days moderate browsing, apps and text. If I talk alot or use my hotspot I only get 1.5 days. It is a little time consuming to get everything just right but when you do you really see it.

This isn't a SetCpu feature there are other programs that can do this as well. It just so happens SetCpu has it built into the program. I bought SetCpu back in my Atrix days and loved it so it does work great for a simple tuning program.

I'm running a kernerl and a custom ROM that allows me to underclock and overclock.
I tried it out both ways and the battery lasted for almost the same amount as on the stock option. As I tend to play games a lot on my phone, the underclocking ran into some issues with stuttering and sometimes force close of a couple of games.
Personally, I've never been a big fan of either .
hello guys im new here and i want to ask how far... the CPU can Overclock without Risk... and i know that a safe O.C is 1.7GHz but use 1.89GHz is good? and how far the Phone is goiing to handle this and the life of the Phone? as i know overlock a Video CArd,CPU can make more short the life of the Device... so is the same with this phone? i know the The Qualcom CPU is 1.5GHz but the normal Speed is 1.7GHz... i dont know why HTC DOWN CLOCK THE CPU... if the CPU can Handle 1.72GHz

I'm not sure how far you can OC this device, but the reason they usually underclock slightly is twofold, heat and battery life. The higher the CPU clock speed, the more heat generated, and the lower the battery life.

SetCPU is probably the most popular and to be 100% honest Overclocking is harmful to these devices there is a reason why HTC decided to place the clock speed at 1.5GHz... there isnt enough cooling provided to really push it past the limits but to each thier own I guess... Ive done it before and I really havent found it to increase the overall usage to my device... I had my old phone OC'd to 1890MHz and the only thing that changed was the benchmark numbers the normal day to day stuff still stayed the same like switching between apps and what not...

I agree with that. I'm mostly interested in lowering the CPU speed for better battery life. Was curious of what everyone was using. I currently have the NoFrills CPU Control app. Although it is very basic, it does the trick. I've been running 1ghz max and battery life has greatly increased. If I feel the need for speed, I just set it back to 1.5ghz. As you said, I haven't found a need to go beyond that.
Same here, OCing increased benchmark scores but no noticeable difference when using it. And when it got hot (really fast when OCing and benchmarking) the thermal protection pulled the reins in and scores plummeted.
You just need to get rid of the bloat and unused services, or install a slimmed down rom.

Any feed back on your experiences yet? I'm currently looking at this as my next phone.
There is an argument to be had that underclocking it wont make any difference to your battery life (unless you keep it fully loaded for the majority of the time). You better off keeping it at the same max clock speed and experimenting with the guvnor settings. The faster the clock speed, the faster you can get something processed and the sooner you can get the phone back into the lower frequencies the better.
If you half the max clock speed and it takes twice as long to process the data you will end up using the same power normally than if you left it at its default clock speeds. Again whether this will yeild battery savings or not is dependant on how you let the CPU ramp up and down. Id rather have a snappy phone when I need it and concentrate on keeping it at its lowest power conuming mode as much as possible.
