Can over clocking the phone can burn or cause damage to the hardware except excess battery usage and does overclock an 1ghz processor to 1.5 will really give a boost or its just a gimmick

Excessive overclocking really did damage your hardware, depends on the quality.. Overclocking from 1.0ghz to 1.5ghz really give a performance boost, in benchmarking.. In real life, only noticeable in process hungry apps, such as 3d games.. Gimmick? Well, if its a gimmick, it won't give any sudden resets or lock ups.. The processor have a safety switch if the temperature increase because of oc'ing.. If it's to hardcore, for example, 1.0Ghz to 1.8Ghz or even 2.0Ghz, for sure you processor will overheat and lock ups.
Well, mine running at 1.5Ghz, no lock ups or whatever..

Good for you though.. Mine can only be stable at 1.7Ghz.. At 1.8Ghz, only about couple of mins gaming, and then hang till forever..

You will barely notice the difference in most circumstances. Even if your phone runs fine at 1.5 or 1.8 ghz it will probably reduce the life of the chip over a prolonged period.

Someone Swyped my idea.
I think it will give minor boost at the cost of burning your hardware

it will help in cpu intensive tasks, that which require lots of calculations, math stuff, 3d drawing done via cpu, faster cpu, better...
in other tasks, don't even bother, there are lots of other things far slower then cpu.
downside, heating, battery drain, increased rate of damage..!
Im using SetCPU for saving battery life. Set the cpu for 384 while screen is off. Noticed quite a difference.
OP, your asking if a overclocked cpu will give a better performance or if it's a gimmick? Really??
Of course it will give you better performance, that goes without saying but the question is, are you willing to sacrifice battery life? The chip will most probably last for years and years if overclocked but 1 thing that kills chips is heat and volts.
I only overclock when I need to and when I'm done I go back to how it was, usually.
My phone is fast enough at 1GHz, dont need overclocking, all games and apps goes fine fine
Most OC kernals are also undervolted anyway so I wouldn't worry about it
to be honest, i use mine with "underclocked" at 800mhz, trying to get at least a half-hour of battery life... i don't see the point in overclock a 1ghz processor, imo, even with a speed gain, the bad side effects easily override the good ones...
i truly believe that overclock my old milestone was the main cause of the problem that happens after...

I'd look at other reasons for your battery life, if it's really that bad.
I'm running at just a touch above 1GHz with no side affects what so ever and get 24+hrs with heavy use, 30+hrs with moderate use and 40+hrs with light use, and that's never turning wifi / 3G off unless I'm in bed when I switch to 2G.
At 1GHz the OCUV kernal I have installed uses less voltage than stock kernal at stock speeds so in theory it's actually safer.
It's not that bad, but it's not so great as yours too. I got about 16hrs with 'hard' use, what is enought most time, but sometimes i get in home with the blinking orange led. Quite annoying...
I try my best to improve the battery life, but i was becoming a battery freak, or something like that, always checking currentwidget...
I get 3 or 4ma at stand by, what is considered normal, i guess... and always use full brightness, hate to use anything bellow...

Full brightness is your problem. I bet it uses like 70% of the current while you use your phone.
going up to 1.8GHz still running stable, thats crazy man!

Very general question. I'm on 2.3.4 4.5.91. unlocked rooted. cam Does anyone use setcpu or JD on this release. It seems as if settings has some battery controls in it. Just curious. Thanks
Sent from my streak7 using Tapatalk
If you are overclocking, SETCPU allows you to control clock speeds with profiles and set lower CPU operating voltages to save battery.
See here for some undervolting info:
http://forum.xda-developers.com/showthread.php?t=1183059
I have not found any software like JD that works on gb.
forgive the noob question, but what is JD?
i use SetCPU, bought it off the market (gotta support our devs, right?) and i'm LOVING it. it does everything i need for managing my CPU, i have custom profiles setup for all sorts of situations, and undervolting gives me amazing battery life. when i'm running Ninja SF, i can use my phone for 25-30 hours without charging (moderate use, no hardcore gaming or music)
but on CM7, i can unfortunately only average about 20-25 hours of battery life with the same use.
JD = Juice Defender
Sent from my MB860 using XDA Premium App
Hmmm ok. I'm on stock not over clocked. Setup may not do much for me. Juice Defender could control the radios. But settings seem to have some battery options for extending battery life.
I didn't know if setup since I am rooted would at least help with scaling and throttling down processor speed when battery reached certain levels. I'm sure these would help on a custom Rom.

I'm getting the Nexus 4 in about a week, just wondering what the battery life is like
if the CPU is down clocked all the way to 1.0Ghz an you under volt it by a few MV?
Also what's performance like at 1Ghz?
Just relax and enjoy your phone when it arrived. You will see that there is no need to do anything about battery. Battery is just good out of box.

Try it yourself in a week, not every phone is setup equally in terms of installed apps and widgets and usage. Other factors like gaming, streaming music and video`s etc etc play a roll in battery life. No one can answer this question for you.
Battery life on this phone is abysmal - on a fresh phone. Didn't restore much from titanium backup.
Would like to drop the CPU down a good 25% or so, can this be done without too much stress? It's an unbranded, rooted i9505 in Australia.
I suspect I'll need to flash something to do so, is that right?

Define "superb" for me.
Apologies for jumping in here. Can you define abysmal too? I would say my battery life is more than double my S2 (that was Cyanogen niggtlies but this is currently djembey's slim). Biggest drain is usually the 3G but I have that off most of the time. It is hard to compare to be fair as we will all use different settings but I have a lot of the bloat removed or disabled, power save on and screen at half brightness. How is yours setup as maybe we can shyc settings a little to compare more closely.

If the reason to underclock is to save more juice, you should understand that the phone doesn't work on 1,9ghz most of the time, on average it's 200-800mhz depending on task, so you would not probably win a lot battery if you underclock let's say to 1.7 unless you're a heavy gamer.

I know this tread is already pretty old, but that answer is only partially true.
On stock configuration the GS4 uses the 'ondemand' cpu gouvernor. That gouvernor ramps up the cpu speed to the max when cpu activity is detected and will then slow down the cpu depending on the task. So everytime you open/close an app the cpu is running at 1.9ghz. (At least that I heard/experienced) using a custom kernel you can choose a different gouvernor which is more battery friendly, or lower the max cpu speed(from 1.9 To for example 1.7ghz). You can also lower the min cpu speed so that when the device is idle, it will consume less power (I think standard is around 350mhz and I put mine on 189). Some kernels even allow to underclock the GPU. Undervolting will also save battery.
In short: using a custom kernel you can really save some battery, increase performance, or get a better balance between the two, but you will have to take the time to find the settings that work best for you. I personally use KT kernel, with an overclocked CPU and GPU, but I also undervolted them both by 75mV, and with some tweaking with settings for when the screen is turned off, my battery lasts longer than stock configuration.
Correct me if I'm wrong on something, I'm not a Cpu expert
And sorry for bad english

Check this out, if you long press the power saving icon in the notification pull down, it will bring the settings for it, Uncheck all but the cpu. It will run no higher than about 1.3 ghz and is plenty fast for all tasks. I use that setting on the s4 and note 3. I never ran into any lag except TouchWhiz home launcher but I use Nova Launcher anyways.
You will see a better battery life as well.
Hello,
I have a peculiar problem with my OnePlus Two
The faster A57 cores don't get activated, I have tried using Antutu, played Asphalt 8 And NFS NL for hours.
But the cores just won't get triggered
I'm using A1 CPU tool to monitor the same.
Even CPU Z wouldn't show me any activity on the other 4 cores while Antutu was running.
Any ideas? It's brand new can be returned

I just installed A1 CPU to verify your issue.
It shows cores 0,1,2,3,4 are used at 1344ghz for me as well.
When i check with synapse (i'm on AK kernel) it shows all cores are used.
I guess it's a limitation with A1 CPU tool. Try with other tool that supports such architecure.
I was sceptical on the same but, out of the box I remembered seeing 1777 MHz frequencies.
Thanks a lot
I shall try more tools and get back.
Though I think if you're on a different kernel and had the A1 CPU tool been correct it would be redundant, Because core allocation would be done on kernel level (in my knowledge).

I know that it was already discussed but maybe someone has found a solution.
The problem is that performance of device gradually decreases proportionally to the level of the battery.
For example:
- battery is 90%, Real Racing 3 runs perfectly,
- battery is 45%, some lags appear during gameplay
- battery is 10%, heavily FPS drop, almost impossible to play
Battery saver is turned off, device is cold in all tests.
If I would like to save my battery level - I will turn on battery saver manually,
but I WANT to have good game experience not depending on battery level
This is really crazy.
Tested on stock OOS 2.1.1, with stock kernel, with Boeffla an AK, tested on Exodus ROM - everywhere I can see this weird behaviour.
May be some system files must be edited to overcame this issue?

Hi Jemcik, hi Denhot!
I'm facing the same issues on my new device and it's definately not normal!
With a battery level of 19% I was not able to get the 4 A57 cores online, which results in lower system performance. Have you found a solution?
@Denhot!
Maybe we should rename the thread into: IS OPT PERFORMANCE REALLY DEPENDENT ON BATTERY STATUS AND IS IT A ROM FEATURE OR AN ISSUE!?

It looks like some system configuration files with kernels activation policy have to be edited,
but I haven't found yet which files exactly.

I've never experienced such a function!
CPU power depending on battery voltage!? 62k with full battery, 49k with 20% battery both with same CPU temps!
Hopefully not a general problem on our side with the motherboard Voltage Regulator or something.
Have you been to a kernel thread and asked this question? If not, I will ask this in AK's kernel thread. Maybe he knows more about it!
The 4 high performance cores will only be activated when needed. What app are you using to check the core usage? Every now and then you should see 2 of the high performance cores sometimes coming to life every now and then, with the other 4 power efficent cores being more busy. Use CPU-Z to check.
Due to the way Oxygen OS's stock kernel works, only 2 of the high performance cores will ever be active, alternating between the 4 cores in an attempt to keep the phone cool and not throttle as often. If you want all 4 high performance cores to be active as well as overclocking it back to its original speeds, you'll need to flash a custom kernel.

Hi,
would like to share I don't have a similar experience, with NFS NL or Asphalt, phone was consistent with no lags even when it got unbearable to hold.
I as playing and simultaneously screen mirroring over to a TV.
Going from 65 to 25% over a long course.
I normally won't let my battery fall below 20%.
So the thing about Li-ion/pro is that as you go lower voltage decreases so to provide same power draw current increases.
Basically it would heat up faster.
That can be a reason combined with that their might be inbuilt measures to save battery like you said, nor as an engineer I would recommend you to stress your phone at those levels.
I can't explain the lag at 45%, didn't find it might try real racing 3 later to check.

This is consistent with what I've noticed. The time It didn't, a simple reboot helped solve it and it hasn't occurred since.
Also these tools can't monitor the other cores, if you're rooted why not try synapse as helkat suggested

Thanks man!
I know how the S810 should work!
But I thought the performance issues have only to do with the temps. But now it seems it have also to do with the battery level.
It would be good if someone tries to reproduce the following to verify it:
1. One run Antutu benchmark with fully charged battery and room cool temps.
To be sure the conditions are the same, shut the display off for one or two minutes, than start display again, kill all recent apps and run Antutu test and note the results.
2. Than wait or do something until your battery is down to 20%, shut the display off for the same time, kill recent apps and start Antutu test run again and compare the results.
I've also tried the same after a reboot, with always the same results.
With 100% I get scores between 60 and 66k and with lower capacity (20%) I get only 48 till 50k!
I am not interested about the benchmark results, but I need to know if this only occurs on my side.

So, guys!
I have tested it the last few weeks and it is a fact that the performance in benchmarks is dependent by the battery level.
We have tested it with 3 devices and it is always the same.
But thank God, it seems on the devices perfomance themselves (in apps/ui) this has no effect!
But each one can replicate this behavior very easy!

I have the same issue! When battery level goes lower than 20%, my A57 kernels become offline. I checked this with CPU-Z and PerfMon. And this is the same on stock or custom kernel. Now I am using Boeffla kernel. The most frustrating is that my UI suffer from this. I have lot of lags in simple apps, such as calculator or some messengers.
Same issue here, there are threads in one plus forums.
I think the threashold level is at 40 % ?? They made this to keep the battery up. You can also see faster battery drop till the 40-30% mark then it is harder to kill the battery.
I am also dissapointed in this, maybe we can search the kernel sources ? Or is there a daemon app that triggers this?
I received the phone with 20%-30% battery, started an antutu knowing how powerfull 810 chip is, then boom 45k same as the previos phone i had with 801 chipset...i was like what the fxck....runing antutu again with full battery - 66k.
well i have run benchmark in back ground with few game and apps .. and checked with cpuz max that i have notice was around 50-60% cpu load still 2 off those a57 cores were off using this device for 2-3 days it always turns off 2 cores for me rest 6 is working most of the time :/ Even in battery saver mode .. i am not sure if this is a cpuz issue as i have not rooted my device yet so cant say properly ..
Also i face some freq. benchmark issue like in benchmark it scores around single core - 690 multicore - 2.6K .. and if i restarts device it scores normal - 1.1K and 4.5K .. i have no idea whats wrong with this :/
20% Battery Mark
The drop in performance at 20% Battery is standard behavior of the Rom and Stock Kernel. The Big Cluster (A57) is completly shut down to save Battery. If you dont want this you have to use a custom Kernel which is able to switch this Battery saving strategy off. Boeffla Kernel for example can do that.
Read http://www.anandtech.com/show/9828/the-oneplus-2-review/2.
They "optimized" the soc.....
No they just turned off some cores so there is no heat problem.
So I think this is my first and latest oneplus.
they've hit the mark! What the hell, i think they must be sued for false marketing. Its just like buying a car with 400 hp and those hp are only there when i'm parked or listen to music, if i'm on the highway or on the ridge the car has 100 hp...wtf :|

Calm down lol it's actually good on their part. Shutting down A57 cores on low battery is a good thing because the A53 cores use much lesser battery. If you're out on a trip and have 10% battery, with the A57 cores this will probably drain off within an hour of intermittent usage. When only the A53 cores are active, the battery life will increase greatly.
Companies design phones for average users, not just gamers. If you don't want this feature, root your phone, flash boeffla's kernel and disable the BCL Battery Driver. It's as simple as that
