Has anyone tested ECO Mode (labeled "Quad Core Control" under settings)?
I'm curious if it improves battery for anyone else. I have gotten about the same results with it on and off. Same goes for performance, no noticeable difference with it on or off.
What's everyone else's results?
I've kept Eco Mode on all the time but I've only had the phone for three days though so not enough time to really test out the difference yet.

Same here no difference. Maybe it overheats less with it on but I haven't fully tested that either

I believe it dynamically sets the affinity for each process on different cores.
So for instance, process A might be on core 0, while process B, C, and D are on core 1, 2, and 3 respectively.
This doesn't account for dual and quad core optimizations by developers, and just assumes that only 4 processes are running (in reality its dozens or more).
The main goal is to spread the work to keep the load down.
Less load = lower clock frequency.
If you've ever done any underclocking or overclocking, each step up uses more power.
Of course, this could also be all wrong, and it could just make the kernel undervolt and underclock and raise the response time between steps.

I have a widget on the home screen that shows clock speed, temp, and cpu load. I have yet to see any differences on it. The temps reach the same levels, it still goes from .384 to 1.512, cpu load seemed to go up maybe 10% if any. The only thing i noticed was that when i would click Home, it seemed to take a bit longer to load my layout. I can't say i noticed any thing different on battery life, which to be honest i have been very impressed with.

I read your post and looked at the screen shots but can't read that language, so I'm not sure which is Eco mode on and which is off.
Can you elaborate on "it really works" please?
the second one is eco mode...
Sorry if I'm late in this information, but apparently Eco mode disables core 2 and 3, and leaves core 0 and 1 running.
So if it's Eco or not really depends on the workload on the processor.

no, with eco all 4 cores work. every bench says that
Hm, well it's either the program just reporting that there are 4 device Id's for the CPU, or it could actually be that the four cores are working.
My last post was just something I picked up off a Google search.

Thought eco mode switches off 2 cores
And only runs in dual core mode
Some sort of hot plug feature

Does using setCPU with the Tegra 3 and it's 5th core muck up the Tegra 3's native power saving capability (ie. using the fifth core as a low energy solution for minimal activities)?
Has anyone seen tests of battery use with and without?
What I have seen from my use over the past week or so with SetCPU is that you can set the governor and the minimum clock both of which have an effect (although minimum clock is not strictly adhered to).
I don't believe the 5th core is exposed to the android OS so SetCPU shouldn't effect that at all.
I'm testing the beta and no it does not effect the max 100% of the time the tegra power management seems to kick in. I have informed mike (setcpu author) about this issue he is looking in to it.

I guess set cpu is not supported quad core yet
As James pointed out, the 5th Slave core is Transparent and not visible to Android, so it 'shouldn't' be effected by SetCpu

It supports quad core CPU scaling, the question is about the 5th core.
That the 5th core is invisible does make it seem like it wouldn't effect this issue, however I would like to understand a bit more about how it works to be sure.
From what I understand, when processor use is low and the CPU is scaled below 500mhz(?) then the 5th core alone is used, whereas at higher frequencies the other 4 cores are fully engaged.
I would just be worried that setting the CPU speed through methods other than whatever method HTC/nvidia had arranged for might negate this benefit. It'd be good to know from the setCPU guy what's going on, since he likely understands a lot about how CPU scaling works...
Here's my Feedback on using SetCPU with HOX:
When trying to underclock my phone
Max: 1000 Min:51
Result: rebooted within 5 minutes and then kept on doing this untill I reset the SetCpu settings to phone defaults and uninstalled
similar user experience here: http://forum.xda-developers.com/showthread.php?t=1596992&highlight=setcpu
I have seen that there is an app created for the HOX:
CoreControl: http://forum.xda-developers.com/showthread.php?t=1652136
I want to give this a go and I feel this a relevant topic to be stickied maybe under a different Topic Title ie. Custom CPU settings
Will install CoreControl and revert...
BTW: what settings have you tried using with SetCPU to underclock that doesnt result in a random reboot and that works, also what version of setCpu are you using
system tuner will allow to set the clocks for T3 properly
CoreControl is for enable/disable cores, not for overclock/underclock, I've been using it for a while, at least my HOX doesn't heat up much

I can now concur with @vegasphinx it doesn't heat up as much and I dont notice the difference besides the toastie popping up every so often saying CoreControl has been granted SU
can any of you give me an idea how to setup the Battery Stats within CoreControl
It crashes because there's no kernal that supports overclock/underclock.

While turning it on. Running some benchmarks. Off. And running benchmarks. I definitely see while its on, its raking smaller numbers. My question is, what does this setting do? Is it under clocking?
My phone doesn't stutter while bits on. And I haven't used it long enough to notice battery gains. What's your experience been like?
Also, I'm not on irc. How's the boot loader unlock coming along? I'm dieing for aosp
From what I've found out so far, it shuts down 2 of the cores. I've noticed very little change in the feel of the phone. Battery for me seems to be about the same. Ymmv.
As far as aosp, read in the development thread. Its close.

Most likely it is changing the cpu governor from performance to power saving, etc. If you've played with custom kernels or over clocking before you will know what this is.

Hi guys, here are results of LS970 in antutu Benchmark X.
http://www.mobile-inform.com/content/view/1194/1/
Benchmark X version is a special version of Antutu in wich all the cheats that manufacturers use are disabled. As far as you can see - maximum cpu speed is only 1188 even if 1512 set in SetCpu or CPUMaster.
please do not compare usual version and this one - the results are different - the results on the right - are from the usual version of antutu at 1500 mhz
Ok...

Our devices automatically lowers the cpu to 1188 when the phone reaches a certain temperature. Try the benchmark when the phone cools down.

it was as cool as ice-cream
i did not feel any heat at all
That's interesting because I have run quadrant in eco mode and had it indicate the clock speed was 1188 and the run it with eco mode and the clock speed register as the expected 1512. Though I'm not sure what is meant by manufacturer tricks. It's not a trick that the cpu can be clocked down when it's not needed.
the trick is any unusual experience.
Usual antutu shows 1,5 , while this one only 1188

It's funny but our stock kernel doesn't support the 1188 frequency we have 1134 then 1242

Weird, I've always had the phone tell me it's running at 1188mhz, regardless of whether that setting is on or not.
I hate how the system decides for me when my phone is too hot or not.
Compared to my GNexus, this thing is an ice cube.
I can only guess, but sometimes the GNexus would feel like it was ~120-140°F during movie playback at 50% brightness.
This thing has never reached more than 30 °C (I do have an otterbox)
It really rustles my jimmes how they think anything above a 30°C core temp is outrageously hot, and gives them the right to restrict screen brightness and core frequency.
Just.. I need my AOSP back.

It puts your un-needed cores into a deep sleep when not needed faster... it's like power saver vs performance mode.
If you want to physically see what it does I suggest this.. download an app that lets you see the state of each of your cpu's like, CPU-Z. Turn quad core off open cpu-z and look at the start of your cpu's, try pulling down your notification bar or volume up and down, and take note of you cpu states and how long they stay that way...now turn quad core optimizion on and do the same. You should notice a difference... with quad core on three of your cores will go into deep sleep quicker thus saving your battery. I personally LOVE quad core optimizion.
Hope this was helpful..:thumbup:
When the f*ck did we get ice cream??
Thanks man summed it for me, I personally can't tell the difference in performance.
Edit: performance as in speed, as in battery life OMG wow!

When on, this option allows the cores to power down and perform at a lesser output in order to save power. When off, the cores will fire up and perform at optimal level with higher output. It's basically a battery saving feature.
For e988 indonesia quad control on mean only 2 core active..core 0 and core 1...never see activities on core 2 and 3...become dual core ...
See with cpu-z and play q internet and q video

It uses different governors, like "powersave" in quadcore turned on, and "on-demand" in quadcore turned off. And those governors not handmade but optimized directly by Qualcomm therefore work better than CyanogenModes ones

For anyone using a Kernel tuner that can register big/little activity.... does ANYONE see the big ever being ramped at all? mine shows deep sleep for about 99% of the time I use my phone and its kinda pissing me off because the phone does lag at times, and if the big cpu were to ramp up, I'd assume the lag would be gone. whats also weird is my current uptime is 26 hours, and while my "little" set shows that as the uptime, my big only shows 7 hours.
T-Mo, stock, rooted...
I've been wondering this for a while. Lots of lag issues and missed taps (for me) seem as if processor scheduling isn't being handled efficiently.

FWIW it hasnt mattered what gov I've used... ondemand, interactive (which was the stock setting) both of these, no big core being used at all
chrisokaly, what are you using to monitor this? I'm using CPU Spy 0.4.0, and it has never made a reference to 1.8GHz. The highest it ever shows is 1440MHz.
But using CPU-Z (which only shows live data, while you're looking at it, not history), that does at least acknowledge the 1.82GHz cores. I'm not sure if I've seen them hit 1.8, but I don't look at CPU-Z often.
Mine is Verizon, VS986, not rooted.
and now that I'm playing with this a bit more... the "frequency table" in Kernel adiutor for the big core seems to reset itself every time the screen goes off...
