My phone is overclocked. but i always lower Maximum Mhz of it to 1113Mhz or lower by useing SetCpu. so i need to know even if i lower the processor speed will my battery drain because my phone is overclocked.
Overclocking will drain battery more, undervolting less
It will unless you also undervolt....undervolting and overclocking on the same time sends the phone in another dimension and without losing to much juice.

What's the purpose of overclocking and undervolting. What's the reason for the undervolting?
Sent from my ADR6400L using XDA App
It reduces CPU temperature and the amount of battery needed. It is especially useful when you overclock your CPU as both benefits are seen then.
Undervolting typically increases instability, unless it is also in conjunction with underclocking.
If you overclock, you might add voltage to keep the processor running higher than its rated speed. Similarly, if you drop the clock cycles, you may be able to drop voltage and run a cooler, more power-friendly processor.
I am currently underclocking to 768MHz on stock voltage.
Is that why with the speedtweak on 1.92 with the under volting makes the phone lock up.

Likely. The only time I experienced frequent locks was when I was undervolted extremely. If you're running an overclocked and undervolted simultaneously you increase the odds that the cpu won't have enough juice to run properly.
Virtually every device will tolerate speedtweak's extreme undervolt/overclock to 1.41GHz with complete stability. Most will also remain stable running within stock voltage up to 1.222GHz. I've never been a fan of running with a hard cap on speed. Adjusting governor settings makes more sense. I'm also thinking underclocking and using HTC stock voltage scaling is a waste since the CPU will definitely remain more stable at more extreme undervolting at those speeds. Some kernels will run well with a minimum voltage of 650.
Is overclock make battery drain?
are you overclocking ? as in are you using frequencies higher than 998MHz?

Yes sure it will consume more battery if you overclock it,but better performance

That's not 100% correct. if you download an app like CPU Spy you can monitor how much time your phone spends on each CPU state. unless you do a lot of gaming and other CPU intensive activity your phone will spend most of it's time in lower CPU states. unless you specify that you want it to run at 1113 MHz at all times which yeah, would kill your battery faster. just looking at CPU Spy on my phone OC'd to 1228 MHz it has spent 70 hours in Deep sleep and 25 hours on 245 MHz. only 3 hours at 1228 MHz.
So unless you do CPU intensive things on your phone you shouldn't notice an overly dramatic change in battery life.
Heya folks. Is it normal for my battery to consume so much since i overclocked my cores to 1.5 ghz each ? xD
Need powah and i like it very much but it fails cuz battery gets consumed very fast. Help !

Yes it is perfectly normal, battery consumption increases exponentially after 1.2ghz and especially even more so after 1.4ghz. All you can do is add a dark wallpaper as your background, under volt each cpu frequency as much as possible for your device, and undervolt your gpu as much as your device can handle. This defiantly won't solve the problem, but it will help off set some of the power consumption. Also, I'd probably recommend if you want to OC but are battery conscious, to only overclock to 1.4ghz. The power consumption at 1.4ghz is a lot less than 1.5ghz for almost no noticeable speed difference. Basically, for our cpu, 1.4ghz is the overclocking/battery sweet spot I hope this helps you
Edit: If you really want good battery but at 1.5ghz, the only really option is to get an extended battery, the Samsung one is really good and adds almost not extra bulk. See here: http://forum.xda-developers.com/showthread.php?t=1239719

do underclocking/overclocking influence battery backup time?
Define battery backup time. Do you mean how long the battery last?

If you mean battery life, under clocking will get you better battery life but less performance. Over clocking will get you less better life and better performance.

Underclocking gains is entirely dependant on how you use the phone. If your phone spends most of its time just sitting around you wont gain anything from underclocking. On the otherhand, if you play a lot of games (CPU intensive) then underclocking will get you a little more game time. For things like texting, checking Facebook, etc, underclocking wont help much as your cpu doesn't spend much time maxed out anyways. On top of that, underclocking means it will take your cpu longer to complete tasks and therefore your cpu will spend more time at higher freqs to accomplish things it could've done faster at a higher clock speed.
Same goes for overclocking, you will only really see a difference if you play a lot of games or do cpu intensive tasks. Another area you might see higher battery consumption is by overclocking the MINIMUM frequency. This will affect battery even while going the little things. How much the effect depends on how high you go.
Neither oc or uc affect your phones stand by time.
Thank you dear for your detailed explanation

What about undervolting? Seems like a much more delicate operation of all things.

I haven't ever really experienced much battery life difference when undervolting. Then again I don't undervolt seriously, just lightly. There may be more of an impact when u do it hardcore.

I underclock 200-800 on demand gov and under volt a decent amt each phone is different how far u can under volt without sod but never set u voltage to set on boot or u mite get stuck but I notice a difference if I forget to apply voltage after a reboot I lose battery much quicker maybe I gain two more hours on my battery but I'm a heavy user with 5 plus hours screen time everyday

First off is this a good idea? can such small devices be over clocked in a safe way without risking damaging the hardware?
if yes which would you say was the best app for doing so?
Hi,
A good idea... maybe, maybe not... it depends on what you want... higher scores in bench?A shorter battery life?A very very hot device while browsing or gaming (if you run at 1.8Ghz for example)?A little extra power for some apps/games?
With overclocking a little (1.5/1.6Ghz) I noticied that some apps open a little faster and the genera UI is a little more responsive...
There is always a (little) risk to overclock our phones, generally due to overheat but also some CPU's can't handle high overclock.
For me I don't remember reading someone burn her CPU with overclocking but...
There are still some software protections before to burn a CPU (thermal throttling, CPU temp limit before shutdown, etc...).
Obiously the duration of life could be reduced mainly if you always run at 1.8Ghz with playing games... So the "safe" way would be no overclock or a little overclock like 1.5Ghz... For you to test and decide...
For the apps: SetCpu, System Tuner... there is a bunch on the Play Store.Just for the CPU settings I would say SetCpu.
For me i will never overclock my cpu. Just install siyah kernel and it's pretty smooth in games. Overclocking will damage your cpu and maybe loose some of the performance.
I can't see the need on this device, I might experiment with uv, maybe even underclocking, but as above, super smooth on siyah, and Slim Rom

Talking about battery life i installed darkys rom 3 onto my i9300 and the battery life is already suffering a loss of maybe around 25%. In saying that over clocking will only cause me to lose even more so ill leave it for now

Overclocking won't damage your CPU unless you set crazy voltages, or let it overheat. Also, it won't lose performance... that's crazy talk. Only if it overheats will it throttle, but that only happens on large clock rates like 1.8GHz or if you're in a hot environment.
I had my old LG GT540 overclocked with no heat problems mind that was only a 600mhz cpu, had it up to 825mhz.
But we already have a powerful cpu in this phone, foe now I don't see the need to overclock.

The best app depends a lot on your kernel and device. For example, for my Galaxy S2 the best OC was with TegraK Overclock.
With my Xoom CPU Tuner is still the best.
With the S3 I suppose CPU tuner would be alright as well, but I haven't had the urge to OC it, because I find SiyahKernel still quite unstable in the S3.
You need an overclockable kernel in order to OC your phone.
As for damages, it is hard to tell if they are permanent, but picture this: your battery will have to be recharged more often, because it will drain faster. Since batteries have a limited lifespan which depends on how many charge cycles they go through, the more often you discharge/charge them, the shorter their lifespan will be.
Also, there is no telling what kind of ill-effects the added heat can do to the phone. It may be totally harmless, but it may also affect the quality of the display, since the added heat will be right underneath the screen.
The lifespan of the CPU will be shortened: instead of being able to work well for 20 years, it will work well for 18, 17, 15, but more than enough time for us to already have replaced our S3 for organic, intradermal smartphones!
