What are the benefits of OC/UV (particularly for CM7)?
I know of improved performance due to OC, but what does UV do in regards to performance. Also, how does an OC/UV kernel compare to one without the option?
your processor doesn't need as much voltage as the stock settings--undervolting lets you save battery
personally i want to know.. do you have to UV to OC?

You can do either or both but don't have to do both. At some point UVing will cause a crash. Right before that point it can cause performance issues. See the link below for instructions on how to find an optimal UV level to maximize battery savings and performance.

OCing improves speed but can also cause stability issues. For a captivate this usually isn't a problem until you get past 1.2 ghz. After that, it depends on the kernel but I have yet to find a kernel that is completely stable past 1.2 ghz under stressful conditions. Samsung designed the processor to handle 1.2 ghz and in theory it can go up to at least 1.6.
Like everyone before me has said, OC will make your processor work more (which will eat up more battery, and send the temps a bit higher).
UV is a way to "fix" that problem by controlling the voltage used by each Mhz/Ghz range. The mini guide that QuarkGluonSoup posted is a great way to start off.
Most Captivates start have random errors past 1.2Ghz, but the highest I've seen (stable) are 1.4Ghz.

Odd as it sounds, my battery life on CM7 is close to 50% better when it is OC'ed to 1.2 ghz and UV'ed than it was on the froyo ROMs under the same conditions.
That really is odd :S I think I'll try it myself.
Hello, everyone. I know that it possible to double the original clock speed on the motorola milestone 1, but how safe is it, in terms of overall reliability? a friend gave me a milestone that has been previously overclocked to 1.2 ghz, and i want to reduce the speed back to about 800 Mhz, but i`m wondering if it`s possible to have already permanently shortened the life of the processor....any opinion is welcomed !
is it possible?? YES
does it reduce the life of the CPU?? YES
did it already reduce the life of the CPU??? i think YES. every overclocking reduces the life of the CPU no matter if its 1,2GHz or 800MHz
AND... YES underclock to 800MHz. i think 800 is a very stable and good speed for the milestone. you will not see or feel any difference to 1GHz or more.
a very precise answer. thank you

Mhh.. 800 GHz seems a little much i think. Try around 700 GHz, your phone should also be a lot cooler
[ sorry couldnt resist ]
Napsterr hit the nail on the head. ANY overclocking will reduce the lifespan of the processor, and harm battery life.
I personally have mine OC'ed to 1.25ghz without any problems, but that is because I know when it kicks I can replace it. If you aren't able to replace it, the safest option is always stock clock/voltage.
yeah i agree with all of you above, 800mhz is a sensible speed……over 800 will make milestone heat up a real lot and drain out battery at a alarming rate……
hello,
im just wondering first of all whats the best speed to OC without permanent damage. I have done over 900 Mhz but I will get maybe 1 or 2 reboots a day so I went down to 864Mhz and its been smooth no problems. but what do you think is best to use.
also taking the first question to mind, what governor and i/o settings should I use to give the best balance between battery life and performance? I have tried smartassv2 and the battery like suffers.
Please give me your opinion for what is the best combination for my phone
Well first of all you can't have both performance and battery life.
If you are after performance go for 883 ( I think. I don't exactly remember the freq so forgive me for that) or what you suggested yourself (864) and set the governor to interactive and min frequency to 245. Personally I would set the governor to performance and Max frequency to 864 min 245 though it may sound crazy but that's my settings, phone doesn't get as hot as it used to battery life has kinda increased actually well if you think about it you will see that your phone will complete a given task in a shorter time and therefore ...
If you are after battery life then don't think about over clocking. In fact you might wanna under clock to certain level.

Hello all,
I'm planning to buy a Xperia Z but I'm also interested by the Xperia ZR that has a better battery life but that is harder to find where I live.
So I'id like to know whether the Xperia Z has a good battery life, let's say a day in advanced use, and no lags if underclocked @800-1000MHz.
Thanks in advance.

If you buy an unlockable device (not from a carrier) undervolting with a custom kernel will make the most difference
@ kingvortex: Thanks for the link but I'd already read the thread and I didn't really find an answer. I saw that for some users underclocking wasn't working properly... Does the problem still exist ?
@ DrKrFfXx: Yeah I won't buy it from a carrier, and I plan to underclock the Z if I buy it, freeze or unistall some apps etc. But I don't want to lose performance. Is the interface and most of apps very smooth at 800MHz ?
Thanks.

Is laggy at that speed.
But don't confuse undervolt with underclock, mister.
Undervolt as the name implies, is lowering the voltage of the processor to generate less wattage and thus, less heat and battery consumption.
You can undervolt your device to consume the energy of the stock 1000mhz and retaining 1500mhz. Undervolting combined with a slight underclock, say to 1350 will achieve decent performance while mantaining great battery life.

Yeah I knew it, that's just a habit for me to say underclock ^^
Anyway thanks for your answer. If at the end of the week ZR isn't available here I'll turn my choice on the Z.

New to android systems, I want to try and improve my battery life and the last thing on my list after looking about was underclocking.. I've got a rooted z3 and the rom toolbox app, after reading the comment what would I need to do to get an ideal battery saver?
Just wanted to share with you guys about the this Konabess - GPU overclocking app. Needs root obviously.
So what does it do? Its an overclocking utility. Which means you can over/underclock and over/undervolt the GPU.
Many of us on the 11 series are experiencing overheating issues and battery life issues. (I myself am, what a ****ty 5000mah battery and horrible heating problems)
So what you can do with this, and my recommendation is to add a lower GPU frequency and at the same time undervolting all of the frequencies.
Just tested it today GMT+8 2021-7-10. What I did is just simply added a 200mhz clock speed and undervolted each frequency by 2 levels. Will see if this helps with the heating and the battery life.
NOTE: This is not a support page or a tutorial. Just a share post.
You guys can refer to this page [TuT] [Guide] Undervolt / Overclock SD865 -Updated 03/14 which is a rather good reference and starting point.
Did you check my battery thread?
Honestly if I would ever make changes to the clocks it would be for increasing the speed and never to decrease
Miui.eu with some debloats. Yeah I did. Some people want more speeds but others want better thermals and battery life.

No I use official global ROM not Xiaomi.EU
