Disable the second core? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Possible to disable second core to save more battery life? I noticed whenever I pulldown the notification bar my second core goes straight to 100% use so I wonder if I disable it I could save battery.

You have to adjust the ratio of the fluxcapicator . To do that

lol don't listen to this guy. I believe faux hss by default set 2nd core to offline, and it only turns on under load. which app are using to monitor cpu usage

Here read this http://forum.xda-developers.com/showthread.php?t=1329585
Would actually cause qorse battery life.

Yes i know thata a diff device but same principal

Yeah, I notice when not touching the screen the second core is put offline, and I would use fauxclock to see that, but I gave up with that and use system tuner now, also shows second core offline but as soon as I bring the notification bar down just a bit, it comes out of it's offline state and that isn't even a 'serious load' occasion so I'd like to just keep it offline

I've seen that post before, but I have a lot of experience I. The technical field and I know as a fact the processor draws more power to use both cores instead of just one

Suposidly the second core only gets used when needed. If your phone was put under the same load with no second core to pick up some of the duty then you are drawing more electricity anyway. 1 core running at twice the load vs 2 cpres runing at half the load. No one knows unless u have a digital multimeter and can test yourself

I haz multimeter also I help manage the military network for my state and have plenty of knowledge on the hardware end leave the second core be it will only use what it needs bro your gonna work the processor in ways it wasn't meant to be worked. But if you don't trust faux who's made some 16 kernels then have you used the disable second core option or was that something you tried

Well i'm looking to totally disable it, as the tasks my phone handles on a daily basis does not require a second core. The hardest tasks it'll complete all day is opening up the messaging apparently which is instant even at 328mhz.

I have to be honest. Why buy an android phone with an S3 dual core processor then? That's defeatist. If your simply using the phone for basic messaging, maybe some email and youtube, a windows phone would have been better suited. Mango 7.5 is very stable, and it runs on all single cores

Thoughts on disabling one core when using CM7 variants

It was suggested to me that in order to prevent excessive battery drain and heat when using CM7 I should disable one of the cores. Has anyone done this? What negative impacts could doing this cause (if any)?

If anything it would increase battery drain due to all the processing being put on one single core, what I would recommend for a decrease in battery drain is different kernels with under volting options. That's what's worked best for me.

It was my perception that the older single core phones had better battery life. Do you really think it would hurt the battery?
Dual core isn't properly utilized yet so it might not be a bad idea.
Here is an example of my battery drain for today with the bricked kernel v1.4.

Changing kernel and undervolting did the trick for me. Getting 20 hours moderate use.

What are your settings?
Most of the time when both cores are on the 2nd isn't doing anything, because the first core isn't even pushed enough to reach max. So, I feel 1 core is sufficient, I'm running 4.1.x w/ 1 core @800 and the battery and speed are fine. Although I see others running speeds of 1.2 and higher, but I barely notice the difference of the freqs. The S3 is so fast that the higher clocks are overkill IMO.

I tried Faux's and it was ok, I plan on trying Bricked tomorrow. However if disabling a core gives even better results then that might be the way to go.

I do see a difference in battery life, which is why I prefer this setup, when we have ICS I will use both cores. But I feel cheated on Ginger so I use 1 for now, and whoever said two cores has better batt is wrong...Logically two cores use twice the voltage, that means 1 cores will save a significant amount of power. A weak dual core w/ 1 core on will have bad life, but a fast on is different.

Every boot, you can make a linux script(.sh) if you want, and then use script manager. But, I'm only testing this for comparison, I can't see the speed difference w/ 1 or 2 so I just use 1. 1 @800 core feels how fast my MT4G did when OC'd @1.4Ghz.

How long have you been running like that?
I run Faux kernel, Joe's RCU, undervolted -50mV and underclocked to 1Ghz, I can now easily make it through the day and I'm a moderate to heavy user. I'm pretty sure disabling the second core isn't necessary, and frankly, if you check out how little it's used, it probably wouldn't benefit that much anyhow.

Completely false. Just because something has voltage across it doesnt mean that it is doing anything. Voltage times current equal power. Using power uses the battery.
You guys need to SERIOUSLY change the way you make decisions. Just because something SEEMS logical to you, doesnt mean it is correct. I see alot of BAD info being pushed around here.
I have CM7 and run Fauxs kernels. I FORCE both CPUs online and run at 1.56Ghz. My standby is around 30mAH...Nuff said.
Something else is messed up. Chase facts, not fiction people.
Another issue? UVing. You guys break so many rules in electrical engineering that it isnt even funny. Ive explained things so many times that I am sick of it. I wont anymore, but will let you know that you have missed some key facts.

Dual-Core Mod

Just saw this on the front page and I thought maybe One X owners will want to give this a try:
http://forum.xda-developers.com/showthread.php?t=1681183
Seems pretty easy to do but i'm guessing this will hurt battery life. Thoughts?
You guys already have a mod like this...kind of:
http://www.xda-developers.com/android/take-control-of-your-htc-one-x-cores-with-corecontrol/
While it's not a mod per say, it's essentially the same concept: turn the cores off and on at will. The mod for the EVO LTE is simply turning on the 2nd core and leaving it on...pretty sure this gives you the same power.
I posted in vipers thread about getting it to work with the One X. I posted the file from our phone that needs to be modded for him to look at, when he gets back to me I'm going to post it over here.

CM based Kernel (In-kernel Hotplug, Optimized defaults)

This is my attempt at making AOSP on the HTC m9 a little better.
Code:
#include <std_disclaimer.h>
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/
Features :
-Hima hotplug (optimized hotplug for big.LITTLE architecture.)
Algorithm that will turn core on and off depending on the load. Currently, it will use the LITTLE part of the cpu (cortex-a53 cores) when the screen is off and it will use BIG part when the screen is on. The core 0 will always be on, for compatibility reason. It will also online a maximum of 4 cores at the same time. (4 LITTLE or 1 LITTLE + 3 big). Trust me, it will still be butter smooth.
-ElementalX governor.
@flar2 governor. It's based on interactive with some additional performances tweaks. This governor focuses on performance, not battery.
-Sweep2Sleep
Allow you to turn the screen off by swiping your finger horizontally on the status bar.
-Usb fast charge
Allow you to charge your device faster with USB port. This will disable data connection.
-Savoca's KCAL interface.
Tune the colors to your liking very easily.
-Dynamic FSync
Allow you to keep writing operation in a buffer while the screen is on, to get better performance. Enabling this might cause you to loose data if the phone crash or runs out of battery.
-CDG congestion algorithm
Advanced TCP congestion algorithm.
-Reduced Wi-Fi wakelock
Should provide a better battery life.
-Boeffla sound
Sound tweaking interface made by @Lord Boeffla. This feature is still experimental and might or might not work.
-Build with latest UBERTC 4.9.4
Optimized through the toolchain provided by @Cl3Kener.
-Various enhancement to CRU, SCHED, EXT4, workqueues and others.
Behind the scene fixes that will make your device smoother or more stable.
Beta version :
Beta version of this kernel can be found here : temp.bbqdroid.org . Those are beta, they might work or not. Use your head.

It is nice to see devs beginning to create something exciting.
This is f**kin awesome. I was actually just thinking the other day that I almost miss the hotplugging I had on my Nexus 5. Also love that it's a CM-based kernel as I've been running Candy5 for a while now. Just flashed this kernel, booted up fine. No crashes or anything weird to report as of yet. You're awesome for including Westwood as a TCP congestion avoidance algorithm, as I think it should be standard in many ROMs and kernels and simply isn't. Temperatures seem to float below 40C during light use, which was pretty hard to do with almost any configuration I had previously.
Very excited to see where this goes. Awesome job so far.

Impossible
About to flash the kernel, thanks for creating one. I can't wait until AOSP is fully functional on the M9 like it is the M8. Do the Faux applications, namely Fauxsound, work with this kernel?
So far I'm really liking this kernel. Battery life seems to be much improved over the regular CM kernel, especially with the screen off. I usually charge my phone up before I go to bed and leave my phone unplugged overnight when I go to sleep because there are no outlets near my bed and I need my phone near me for important calls or sometimes texts from the gf. Usually, my phone used about 7-10% battery (if not more) overnight just laying dormant. Deep Sleep on the little cluster would be somewhere around 50%... This morning when I woke up, I was pleased to see that my phone, despite having received over 9 MMS, used only 5% overnight (9 hours of sleep -- Day off, I slept in lol). Maximum CPU frequency while the screen is off was capped at 1248MHz, Deep Sleep came in at 75% overnight, which is a huge improvement.
I'm going to mess around with the settings some more to see if I can improve screen-off battery. I've got the maximum CPU frequency capped at 960MHz now, so hopefully that improves things a little. What I don't want it to do is wake more cores because of the lower frequency. The tasks the phone is performing while sleeping isn't as important as the workload the phone faces when the screen is on, so I don't care if something takes longer to execute due to a lower CPU clock. If a there were an option or tuneable to set the maximum allowable amount of cores awake while the screen is off, I think this would be fantastic.
Currently there is no tunable for it. You can only change the max screen off freq. I could however implement a max screen-off core, that would limit the ammout of core to the said limit or a single core screen-off switch. Whichever would work best. Working on fixing the screen-on time first tho. I believe the load is poorly calculated and therefore the hotplugging algorithm jump too much around. I am trying to find setting that would be suitable for the calculated load, if that doesnt work well, I'll have a look at how things are calculated.

I think the first option would be better. Have it set as a tuneable that people can change, but set the default maximum amount of screen-off cores to 2. Having only one core going while the screen is off is bound to create music playback issues (skipping and hitching) much like it did with my N5. The Hotplugging doesn't seem too bad as far as bouncing around too much, but I have noticed it does like to go from 2 cores, to 4 cores, and back to 2 cores pretty frequently. This is while the screen is on obviously, but nothing really going on in the background. The amount of CPU this phone uses while idling is staggering. I have no idea whats going on behind the scenes, but there's no reason to be using 30-50% sometimes just sitting at the homescreen.
Just doing some interesting testing, if you guys want to try "BETA" kernel, have a look at this : https://temp.bbqdroid.org/
Those kernel should not kill your device, but they are beta so expect bugs. Always keep a clean zip to flash. Also, don't download one if the size seems suspicious, my script does not make the difference between failed and succeed build.

I'm about to buy this man my favorite French Canadian beer. Just flashed the latest beta (R22l) and I'm loving the new features. Minimum # of cores set to 1 for supreme battery life. Maximum # of cores with screen off is set to 2, which is perfect for battery life and smooth music playback. Can't wait to see how my battery life is tomorrow with a full day of usage.
One thing I did notice, however. The phone seems to utilize the Big cluster much more often now. Sometimes only two cores will be online in the little cluster and when they get hit with a moderate load, 1 or 2 big cores will fire up instead of waking up the other two dormant little cores. I'd much rather see all 4 little cores get hit with a workload first before waking up the big cluster. Unless that actually results in worse battery life or something?

I updated the intelli_plug driver to latest version from faux which use a completely new way to online core. I don't think it use the 1 after another way, but, the Online which ever core works best for you. I suppose, AND THAT IS ONLY SUPPOSITION, that the decision is made by the soc instead of the hotplugging algorithm, which might end up in better battery life. Still some test to do tho.

Ok, so i checked this out a while and actually currently still am....once i get done charging the device I'm gonna give it a battery cycle for everything to set in, but I'm using a slightly tweaked base of the profile you posted with certain settings adjusted for responsiveness of UI, that I'll share once my experiment is complete, along with a clean install of ds battery saver pro set up to toggle all connectivity when the screen is off based on all kinds of configurable settings and scenarios, but basically mine is set up to not totally dialect mobile data during the day when the screen is off, but at night it'll kill everything and just correct and sync for 2 mins every 2 hours- it's pretty slick i think- anyway I'll share my settings and results after a battery cycle or two and maybe a bit of fine tuning for anyone that's interested- in fact maybe I'll just pop it into another thread and keep Tek's rom thread from clutter
I just wish I can find a way to make sky high kernel v 3.9 and synopsis work where I get faster speeds then the stock not five. I have tried everything and the only thing I cam close to was 83598 for speeds. I want to get around 9 if it's posable. With out the phone shutting off

Clear settings in synapse and restart-> wait 2 mins, launch synapse-> hit understood then the square box at top right, then three dot menu and hit select all globally and apply to set some defaults-> now set a57 cores to 500min 2400 max, all governors to performance profile, a53 cores set to 200/1600, performance profiles, multicore performance and everything else disabled, gpu 160/852 and leave gov alone, leave all voltages stock everywhere-> set row scheduler and leave else default-> turn on everything in crontab, network all default-> restart synapse hit the X At top of it pops up AND LET DEVICE SIT FOR 2 MINUTES, now reboot and put your device in your freezer for 5 mins-> During this time synapse boot should've shown but you can check synapse if you like and make sure there's no X at the top-> check thermal and temps should be near 20 degrees or under-> run antutu, start test and return to freezer til compete- > remove from freezer, be amazed

Amazing guidance. What are the deault volts of 2.2, 2.3 and 2.4 GHz freqs for you? If these are 1062,5 on yours too; performance governor for a57 may causes reboot. Fyi
Awesome thread gang!! Thanks for starting it up. This will keep @TEKHD rom thread on topic and allow us geeks to lean and master Synaose (hopefully,) lol. I'm OK in it but not so good when it comes to the under/over voltage sliders so that's what I'm here to learn more.about personally. I have a pretty good grasp on most of the other stuff in general so prob about a 69% out of 100 as far as know how but this is great! +1 all and esoecially to @drbveb88 !! Woot!!!

All my frequencies from 2100 up are 1025mV default and i start undervolting from there -50mV @ 2300 and step down from there

@muffinsmuffy (Dont know much about it -shutting down- but). I think, Exynos needs the hotplug support(I saw that on my lg g3 -SnapDragon processor). (6 days deep sleep and just %1 drainage, woahh I want that so badly.)
So, Only cpus stay offline when I set them under 'multicore' section. (6 cores work sweet ). Sim-sung is really not behaving friendly but UITA likes to play with their sources, umm maybe not#
Well on stock A57 cores remain off until needed then kick in under load but that can't be implemented sadly on our kernel or we wont have frequency control over the cpu i noticed that once before on note 3 but had completely forgotten about i just find it a shame that cores stay on for no reason but it shouldn't effect anything

Like they completely shutdown on stock and stay at off state not on minimum frequency would have loved that on a custom kernel

I've never realised that on stock, I bought the device, first day realised deep sleep issue was remaining. In the third day it lost its virginity. Stockish stuffs are really not my type, am happy with whats been developed for us ?
Here here you said mate as long as we even have development im happy because these Samsung aholes dont release nothing

I wouldnt call them like that. They're just not doing perfect but we're still using their devices. They dont release sources right but what would be even no release of device to use lol Think twice, Hallelujah.

Ah then we move to different manufacturers if they don't release me and allot of people are about to completely give up on Samsung if you see the replys to emails i had sent when i asked when are the updates due and there response was they dont have an eta sadly if they don't bring back sd card and removable battery i wont be on the Samsung train anymore ive loved there device's so much but the knox and other rubbish they are putting and removing from devices its like they dont know what they are doing and what customers want not to mention fixability just to replace usb board will have tear the screen apart open the device to replace the battery is a huge risk i feel the note 3 was the last honorable device from Samsung been with them since the s2 and first note but they are losing everything that made them great might move to lg heard they are working on a custom core [emoji108] hmmmm excellent

Quick question on the gpu point ive undervolted mine -50 overclock 852 but on 852 i thought voltage was a bit high so undervolted to 806 mv to so far seems stable but anyway other then antutu to test gpu stability

You're right but, they dont care what people think about them and wish.
Moving to another brand? Exactly what I've done before. Too many years have used Htc, lg, asus, Imate and bunch of devices. I was happy with LG G3 and Meixu mx4 combination.(I was done with Samsung after S3) LG and Htc developers have had all of the rom/kernel capabilities and they have done too many perfect job with snapdragon devices. Appreciate for that. For me, physical looking is a priority. If it looks good, I get more interested in. G4 _ v10 not looks good as edge plus. Its now ok with me, it should be. I will move to another brand when I find a better looking device than edge plus Also removable battery and micro sd support specs are what I am looking for a good device in. Another off topic lol. Sorry for my sick grammar, but my accent is good lol, seems British

I didnt touch the gpu volts much. Its gettin me annoyed when the device is shutting down during the 3d test of antutu. Here is mine. 266- 700 always.

Yup.
Yeah I'm just gonna go ahead and subscribe to this thread. Good on you, OP.
I'm a total Synapse noob and I'm looking for the best possible battery saving profile while maintaining a smooth UI. For now, I'm gonna stay away from the voltage sliders and just set my governor profiles to battery and see what happens. If anyone else has any other suggestions for better battery with a smooth UI, I'm all ears. Not too concerned with benchmark tests.

Can anyone help me understand?

Can anyone help me understand this?
What program are you using? think the antutu benchmark is screwed right now as it CANT detect multiple cpus for our device...

That's what I was using. Any recommendations for a good benchmark?
I believe a lot of people are using the 3dmark for benching... honestly, i benched my phone when I first got it and it was around 58k I rarely have ever seen it higher. I was reading a while back that the antutu program cant see all of our cores correctly and thats why we get such low scores atm. I havent used 3dmark on this phone so cant really give you a comparison to mine. Are you super anal like me and just want to see the max capabilities of your phone vs others or just for piece of mind to know your phone is rock solid/fast? I go for both =D I want to see what my phone is like compared to others, but in the long run i think that does more damage than good. All these notes should be running identical and we dont know what settings and or apps other people have when they run the benchmark, the only for sure would be to make sure that every single person that is benchmarking is on a stock phone with NO tweaks or apps installed other than the benchmarking software..then compare..

Also, if you go to the main samsung note 5 page on XDA there is a benchmarking forum you can read through to get a better idea.

There is a link to it, but, I think you might end up driving your self crazy like I did going through it all.. lol..

Thanks, I really dint cate about the score, I just want to make sure that I don't have a problem. Dunce my multi core, and 3d don't appear to be skirting at all.
My antutu also would NOT run the garden scene correctly with out crashing after a few runs. had to reinstall to work and then eventually said F it.. lol..
Its hard to say when things happen to the phone that slow it down, most of the time it is an app... but the best option if unsure is to master reset and install only that app that is giving you issues and see if it fixes it. Also paying attention to comments on the app to see if any other users might be having the same problems before doing that master reset..
I usually find a new game or a game I know is graphic intensive, like hearthstone, GTA games or other and if the phone plays it fine, then no worries!
