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

I'm running Bullet 1.420 Kernal, what's a good setting for setcpu for profiles and such? I've been a vibrant rooter for a long time and never looked into it, thanks!

Are you aiming for battery life or performance? If battery life is your goal, try what's in my signature. If you're going for performance, the simplest approach is to set your screen-on profile to 1420 (or performance governor) and nothing else, and your screen off profile to 800.

Oh okay, thanks, but what will happen if I put 1420 high and 100 min? Cause I want my Kernal to be free and not suppressed at the standard the phone puts, will that "free" it and will it kill battery faster? I hope you get what I mean, lol

Shouldn't be a problem setting 1420/100. The biggest problem I've found with overclocking is the "Sleep of Death", which occurs when you don't have the proper settings for screen-off mode. At 1200 OC, it's recommended to set your minimum frequency to 400 to avoid Sleep of Death. I believe at 1420, 800 is a safe bet to avoid Sleep of Death.

Oh okay, and Overclocking OBVIOUSLY kills battery right? Ans would 1420 high, 800 min kill much battery?

All depends on how you use your phone. When your phone is on and you're gaming which will ramp your speed up to the maximum, then yeah. You're gonna burn more battery. I'm more battery conscious myself, and find my UI and experience smooth as silk at 1.2 with Bali-X while still getting massive battery savings with the phone spending most of it's time under 800mhz when I'm doing less intensive tasks like SMS.
At this point, your best bet is to simply test it out. Your mileage will vary depending on the ROM and kernel version you use.

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

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!

lol... I would always underclock to the 1200Mhz range to save battery, or use the stock 1512 with a more conservative governor like Intellidemand, rarely ever overclocked and when I did it was just to test something or run a quick benchmark, never really saw any real gain to it at all, always thought it was better to lower the bottom end as low as you could get it to 96-192Mhz so that even if something kept it awake, it would barely be running.
Whenever I'm running "Intensive items" I sometimes overclock. Most of the time I try to underclock to save battery as ace said. Although Doesn't really save that much battery. I stay at stock 1.5GHz a lot though...

True... Underclocking the top end doesn't do much, although if you can lower the bottom end, and undervolt some, it can make a big difference when sleeping.

O you're saying when sleeping. Holy crap YES!! It makes a HUGE difference. I run sense 5 a lot (running that right now) and the battery life on "sleep" is already great, but when I underclock like I did the other day, I forgot to plug my phone in that night, it was at 5% I woke up and it was at 4% 8 hours later only 1% lost. Of course thats on Snuzzo's funky kernel and underclocked, but DANG!!! NEVER seen my battery life that good. The 4% also lasted another 5 hours without use! Don't know how but it did. :laugh::good:
Depends what I'm doing, usually under clocked to save battery throughout the day. I used to record YouTube videos on my rez, I would over clock for recording and benchmarks, finding the perfect i/o scheduler, governor and clock speed to run stable was fun.

I'm on OOS + SPHINX and using kernel auditor I've set the big frequencies to max at 2803mhz and the big governors to Performance, little frequencies and governors are unchanged. Will it damage my hardware in any way?
I think not.. coz it's supposed to work that maxed out.. and the only thing that will be affected is the battery life..

Okk thanks a lot bro
Not much of an effect as long as you didn't also set the minimum frequencies to max! (that will just eat up your battery and decrease its lifespan due to needing to recharge more often).
TBH, why are you messing with the CPU anyway? The 845 is so overkill for today's apps to the point where underclocking it to get better battery life is a very sensible thing to do especially if you're using Franco kernel.
