I have a doubt , whether enabling two core and disabling the other won't cause damage to the enabled one as they will be overclocked when performing some high end task ?
I am afraid of that and not disabling the two . But I like to use if they save battery.

Overclocked? They will run at a maximum of 1.5GHz, regardless of how many cores are active, unless you overclock them.
I have my One X constantly set to dual core mode and haven't experienced any problems as of yet. Quad-core is massive overkill at the moment on Android and is completely unnecessary.

Won't they get destroyed as they are running at maximum clock ?
Do they save battery , enabling only two cores.

Setting it to 2 cores is really pointless for batery savings since it almost never goes to 3 or 4 cores unless you play graphically intense games.
Besides that, yes it is safe.

No, I highly doubt it. 1.5GHz isn't the maximum this processor can physically reach anyway, it's just the cap that has been implemented. It's the Battery and CPU heat you need to be worried about, these can cause real problems. Fortunately, disabling 2 of the cores also reduces the Battery temperature quite drastically. I've not done much testing with CPU temperature though, but it certainly doesn't seem to increase it.
As for battery life, I've not noticed a huge increase in battery life but it does seem to be a little better. This could just be a placebo effect though

I'll add to meltus post.
CPU will only hit 1.5 on 1 core, 1.4 on 2 cores and 1.2 on 4 cores.
CPU is good upto 90c so CPU temp isn't a worry but HTC seem to think that 48c is over heating for the battery where it is ok up to 60c.

This goes along with a thread I was in earlier. You could use tasker to create a profile to enable 4 cores (and in the case of our other thread, the interactive governor) when playing a game, then disable 2 when exiting the game. You can set up Tasker to do all kinds of cool things for battery management and all automated too.

This is a short guide with a few apps that can save a lot of battery life when used correctly. They will not drastically affect performance for most users.
Root is required for these.
First App - Juice Defender Ultimate (https://play.google.com/store/apps/details?id=com.latedroid.ultimatejuice&hl=en)
There is a lot of talk about if this uses more battery than it saves. But from my experience it saves a lot of battery. It mainly does this by turning off data/wifi while the screen is off and schedules it to turn on for syncing. Sure, you could do this yourself, but why not automate it?
Settings for this go as follows.
STATUS TAB---advanced
CONTROLS---mobile data, enabled---wifi,enabled---autosync,ping---disable everything else
SCHEDULES---enabled---frequency,15m or 30m.---duration,30s---controls,default---night,enabled,whenever you go to sleep to when you wake up,---
TRIGGERS---battery,enabled---threshold,5%---charger,ac---screen,enabled---traffic enabled---threshold,normal,30s---location,enabled.
If I didn't list an option keep it on it's default setting.
Second App - SetCPU (https://play.google.com/store/apps/details?id=com.mhuang.overclocking&hl=en)
This is what we will use to keep the processor at the power it needs to be for certain situations.
PROFILES
Temp>40.C------1000max 51 min---priority 100 (this keeps the phone from overheating and damaging the battery)
Screen off-------340 max 51 min---priority 95 (saves battery while screen is not on)
Charging--------1500 max 51 min--priority 90
Battery<10%----1000 max 51 min--priority 51
Battery<31%----1200 max 51 min--priority 46
Battery<51%----1400 max 51 min--priority 41
Battery<101%---1500 max 51 min--priority 31
Third App - CoreControl (http://forum.xda-developers.com/showthread.php?t=1652136)
This app while allow you to turn off cores of your processor.
Set this to use only 2 cores. This will save a good deal of battery, the only time you really need 4 core is for tegra gaming. You can just set it back to 4 if you plan on doing a lot of gaming.
Other tips:
Use a tweak such as the one in leedroid tweaks to lower autobrightness levels. This will save a noticeable amount of battery.

Yea but it still actives more than 2 cores when doing general tasks sometimes, it's more of a guarantee it won't ever cross 2 by using the app, or editing the tegra_hotplug file itself.

Yes it doesn't use all 4 cores all the time, but occasionally it will use more cores than it needs to so to get around that you force it to only use 2.

And you think that "occasional" usage of 2 more cores will drain the battery significantly enough to make this change?

It may not save tons of battery, but every little bit adds up and it's worth doing because it doesn't affect performance for many people. You could also play games using only 2 cores which would also save battery, versus using all 4 cores.

Well its to save battery, and it's exactly like your analogy to fuel consumption. You sacrifice some potential, most likely never used performance for more battery life. How many people with a v8 race it on an open track everyday full-throttle? But how many people use their v8 to commute to work? There's are other reasons people may have bought this phone then to run it at its max performance all the time. I didn't buy this phone with the intent of playing tegra 3 games 8 hours a day. I liked the build quality, the camera, the software in addition to its processing power. Obviously if you want to use all the performance your phone has to offer then disregard battery saving options, I just know there are some people that would rather have more battery life.

I agree I've tested locking it 2 cores vs 4 and there is not enough battery improvement to even consider it and as for juice defender I can do that using power options widget or the sense quick toggles removing the need of that app saving more power.
And set CPU still allows for your clock speed to go over max set.

I have to say that maybe you have a point here. Some people will be surely interested in some more battery juice.
not a great believer myself regarding juice defender or any other similar apps..but kinda changed my mind regarding them few days ago and have seen some considerable difference..i know with the way android is now you can set them all yourself and i fell for the hype and got juice defender ultimate....but so far not complaining...time will tell

Relax.
Battery life for the first two weeks will be appalling, but after two weeks it settles down. You should expect no mpre than 24 hours with average/moderate use though.
Plus for the first 3 or 4 charges, mine was also getting quite warm. What is happening to you sounds completely normal and should get better over time.
What software version is it? (Settings > about > software information)
How much screen on time does he get? (When almost flat: settings > power > battery use > screen)
What is he normally doing when it gets hot?
I noticed my phone was over heating (red/green flashing led) when using YouTube desktop page while charging. Then I turned of the 2d hardware acceleration in developer options (This is off as default) and it stopped. I also gained 30 minutes of screen time.
Also, when you say overheating, these things do get hot, that's normal, can you define overheating?
I use Android Revolution HD 6.0.0 (1.29.401.11) and my phone gets "very" hot after 5 minutes while playing Shadowgun THD.
Not only the backside of the phone, but also the touchscreen gets very hot, so that it doesn't feel comfortable to touch it for more than 3-4 seconds...
Hope this issue can be somehow fixed by new Tegra-Drivers or something else...

You do realise that ambient temperature across the world varies by over 60c? Your statement is meaningless for somebody who lives in northern Sweden or Egypt, for example.
I'm in the middle east our temp is 25c today I just gamed Sonic 4 episode 2 for one hour CPU ne er crossed 72c and batterry around 45c
.....by the way lots of apps in the background will increase temps during gaming
and remember firmware 1.29.401.11is the best in terms of temps, worst was 1.26
Wait for a week or two before you root. In case something is wrong it would be hard for you to return. By the time the hardware will settle down.

i have the same suspicions, were you ever able to confirm this?
How much can the phone be underclocked while maintaining the stability of the system?
What would happen if i set Max freq to 600 Mhz?
What is the best thing to do to save up the very last bit of juice in the battery for emergency situations where i would only need the phone and message facility? Besides switching off Bt,wifi,sync.
Im asking because i was wondering if underclocking "too much" saves a substantial amount of battery when my battery is quite low and I am "hours away" from a charging port!
And is there a way to change the carrier name on the notification drop down to whatever we want.
Sorry if i sound noobish or if a similar query has been asked before
Thnx.
Underclocking the CPU dramatically isn't going to gain you a great deal in the way of extra battery life because:
1. Unless you are heavily taxing the CPU (complex 3d games etc), the biggest drains on the battery are the screen and the radio.
2. If the screen is off, the phone will drop the CPU frequency right down anyway.
The best way to get extended battery life is simply to carry spare batteries!
Regards,
Dave

I think 600mhz is way too low and counter productive or for that matter anything less than 1ghz. The phone will lag alot and you'll have freezes. You'll probably end up using up alot of the battery life trying to get tasks completed. You could try leaving the stock clockspeed 1.6ghz, set minimum cores to 2 and slightly undervolt to -25mv, leave the gpu setup to its default 533mhz and also undervolt to -25mv using a kernel that supports stweak app. Then run an app called Stability Test for 10minutes to check for errors.
Also I tried Go Power Master, which can be assigned to disable certain features once your battery hits critical low levels.

This might be a question better answered by Samsung (unless it is a carrier model). Many questions though....
Does it get too hot to hold? Are you charging it while playing? Is your tablet oc/ov? What is the ambient temperature where playing?

But its not a problem. Your device will power down or turn down CPUs when you reach a certain temperature threshold. At least I know my phone does. I've never seen temperatures like that on any of my devices. The most I've ever seen even when over clocked to 2.1 GHz is in the 50s. Even then I'm not worried about it damage isn't done until the high 80s 90s. But how are you getting these temps. Are you outside in 90 degree heat gaming? I even have my GPU way over clocked and I never seen 70.

And I have an app that monitors cpu temperature while im playing so I can see it in real time. Maybe your device is having a problem. Oh do you have a real thick case? That can cause heat buildup. If I leave , y case on my note 2 while playing a game it causes less heat dissipation and runs almost 10 degrees warmer. You might wanna consider that

Why will undervolting harm your CPU or battery? I can see stability issues with undervolting and have experienced them while experimenting with the settings. I cant see how it would harm the hardware though. As someone said above. The device should shut down if the processor gets too hot to protect itself. Also, undervolting should reduce the temperature.
The built in powersaving option in touchwiz will underclock your cpu to 1.1GHz. you can set it back to your standard setting with a push of a single button the menu.
I overclock and undervolt and have no worries about damage. I have had issues with my tablet turning itself off sometimes, but it has only happened on particularly hot days. I reduced my OC from 1.8 to 1.7Ghz. And i reduced my undervolt from -75 to -50 vs stock as I was having the occasional crash.
Are the CPU and GPU on the same processor or located in the same area of the tablet? I hear alot on hear about the CPU temp making the device extremely warm but wondered how the GPU acted. If you underclock the CPU, does this put more load on to the GPU when playing games or will the GPU load be the same regardless.

i cant undervolted because the CivZ-Sb kernel is not working with 4.2.2
Hello all, I've been away from Android for almost 4 years. I've been reading about the Snapdragon 820 and I'm not understanding why Samsung has 2 cores at one speeds and 2 at a lower clock speed. Is there a reason for this? Seems kinds strange seeing as the 820 is capable of 2.2Ghz on all 4 cores. Just trying to understand why this is and if this makes any difference in performance.
Thanks!
However they are using them, the primary reason is almost certainly reduced battery consumption, with reduced heat production a strong secondary reason.
If I was guessing, I'd say the low clock cores are handling things like doze mode and the always on screen.

Thanks, that's what I figured. So I'd the SD820 a quad core or 8 core SoC? I'm seeing conflicting things about this all over. I do know the Exynos chip is 8 core SoC.
Sent from my iPhone using Tapatalk
It is a 4 core cpu but they are divided in 2 clusters and work independently one of the other. The cluster clocked at 2'2GHz is tweaked for high performance and it is dedicated for heavy stuff. The cluster clocked at 1'6GHz is tweaked for lower power consumption and might be more efficient at lower clocks than the other cluster. It is not a Samsung thing, the SOC was designed like this by Qualcomm, you probably could not run all 4 cores at 2'2 without draining too much power and heating up.
