This application was tested on JB (Android 4.1.2) and requires "root" permissions.
None of the settings are permanent. Default values will be restored when you restart your phone.

LG Optimus 4X decreases CPU frequency after battery temperature reaches 43 °C to cool the device.
If you play a game for a long time, battery temperature reaches 43 °C rapidly and the game starts to lag because of frequency decrease.
This application sets the Tegra3 "temp_throttle_skin", CPU governor and GPU frequency values according to your preferences when you switch "Boost" on.
So you can play games with higher frequencies and more CPU cores without being effected by the heat increase.
Boost Preferences
Temperature threshold (temp_throttle_skin) value can be set to 46, 48 or 50 °C.
CPU governor value can be set to interactive (default), ondemand or performance.
GPU frequency (3D and 2D) value can be set to 200 MHz (default value), 330 MHz, 380 MHz or 416 MHz.
Your device may feel hotter than before after you set "Boost" on and play a game for a long time.
Other Functions
It's possible to see the CPU usage and frequency by setting the "Show CPU Usage" switch on. This has the same effect as enabling "Show CPU Usage" setting from the hidden menu.
If you enable "Unlimited Temp. Charging", you can continue to fast charge even if slow charge is activated because of high temperature.
New function: If you set "Keep Brightness" switch to "On", LCD brightness will be kept at the level you specify at the "LCD Brightness" preference. Temperature rise will not lower the brightness.
"Keep Brightness" function does not work properly for high temperature conditions.
Although brightness seems to stay at the level you specify in the notification tray, it is actually decreased when temperature rises.
This side effect occurs only when you play games for a long time with high temperature levels.
Please follow the new versions of "Tegra Overclock" application for a proper way of avoiding LCD brightness cutter.

WARNING
Use at your own risk.
Turn "Boost" off after you play your game.
Battery will drain faster when CPU governor is set to "performance".
Overheating may damage your phone hardware.
The code to change CPU governor was taken from the "No-frills CPU" project. Thanks to Luca Santarelli for making his project open source.
Shell commands to change GPU frequencies was taken from the "Tegra Overclock" application.

Release Notes
v1.5.1
If the kernel supports GPU frequency higher than 416 MHz, this maximum frequency can be selected in the GPU Frequency preference.
v1.5.0
"Keep Brightness" switch was added. Now you can keep brightness at the level you want regardless of phone temperature.
Note: This function requires that "Brightness Service" keeps running. If you kill the service with a task killer application, brightness will not be kept.
v1.4.0
"ondemand" CPU governor option was added to preferences.
Current CPU temperature is displayed under "Temperatures" section.
Minor user interface changes.
v1.3.0
"Unlimited Temp. Charging" functionality was added.
v1.2.3
Minor bug fixes
416 MHz was added to GPU frequencies list
v1.2.1
"echo 'Y' > /sys/module/tegra3_clocks/parameters/detach_shared_bus" command was added to program startup to prevent crashes that happened when GPU frequency was set.
v1.2.0
GPU frequencies for Boost can be set from "Boost Preferences" section.
v1.1.0
Temperature threshold and CPU governor values for Boost can be set from "Boost Preferences" section.
v1.0.0
First release
FC on kholk's CM10.1, ups!
I think this is for stock kernel only.
just a small tip from me, use more than 48°C for skin temp. i'd suggest at least 50.
'cause the throttle will kick in even before the temp_throttle_skin value is reached.
also performance gov is not the very best choice IMO. it produces too much heat, 'cause it would be enough to run @ 800MHz (or another freq, just as an example)
But nice work anyways

Thanks for your precious comments.
So you recommend to set 50 °C for temp_throttle_skin, no change for CPU governor and 800 MHz for maximum CPU frequency.
Is that right?

Interactive is the default CPU governor and is fine on JB but it really helped to boost games on ICS.
Maybe I can make CPU governor change optional.
New version (v1.1.0) was released.
CPU governor and threshold temperature settings can be adjusted under the "Boost Preferences" section.
Thanks for your precious comments.

partly yes
- I'd use at least 50°C for temp_throttle_skin.
- CPU gov, maybe ondemand, it "likes" higher frequencies --> good for gaming
- and no, please do not cap the freq it was an example of what is bad at performance governor. (800MHz actually needed, but it is forced to keep @1.7/1.5GHz)
but you could increase the min freq during gaming to 500MHz or something. that way the quad core stays online and doesn't change to LP mode. this can slightly improve the performance a bit
Can you suggest if i should add gpu frequency change option for boosting as in the Tegra Overclock application?
I would be glad if you have an optimum gpu frequency to play notoriously lagging games without any problems.
Some of my friends suggest setting gpu frequency to 416 mhz to play need for speed and real racing. Is that the right frequency?
Sent from my LG-P880
Nice idea..
Great idea for our 4X! :good:
will test it soon..
But, i think this should be moved to themes and apps..
New version (v1.2.0) was released.
Now you can set GPU frequencies to use for Boost mode.
Can a moderator move this thread to "themes and apps" section if that's the right place for an application?

well, the N7 uses 416 by default. this should be a pretty good value, regarding performance AND battery.
if you want more battery life, i'd suggest 330 MHz.
for really, really hardcore gaming 520 (564/600) MHz. but this will cause heat, too...

See where it starts going down in 25mV intervals, do that all the way to the bottom (the app there is Kernel Tuner). The top two frequencies can be dropped by 25, but from there and any lower on the top two and you'll get an undervolt forced reboot. Some of the low end freqs might be able to go a bit lower than what my scale gives, you'll just have to test yourself since every phone is different in the undervolt department. And do not set it to activate on boot until you've pushed your phone a bit and know those voltages work. It is possible to undervolt brick a phone forcing you to do a factory reset to remove the saved undervolt values (or a full rom install if you save bad undervolt settings in an init.d script).

Guessing at the rom....probably PAC 4.4, but like Techno said, that really doesn't matter. And those are lowered.

It doesn't make a big difference for me, but you should just try and see it yourself.
Note: I'm not referring to the CM Profiles such as Home, Work, etc.
I haven't purchased Tasker, nor have I used the program before. Is it possible to get Tasker to change CM11S kernel profile to Performance when screen comes on, and Power-saving profile during night hours? I am preferring Performance instead of Balanced at the moment because it makes quite a difference in responsiveness and smoothing out scrolling, but it's probably eating away at battery during non-use.
Or am I just better off waiting for a non-mpdecision custom kernel to be more stable and just use that instead? Franco for e.g.

U can modify the highest and lowest CPU frequency with tasker which is sort of what you're looking for
Yes, you can modify the performance profile using Tasker but I you need to be rooted to change it. This is how I am using Tasker to change my CPU profile when my screen is on and off. Obviously you can change CPU settings on your own accord.
Screen off (powersave mode):
(leave CPU at 0)
CPU governor to powersave
max frequency to 1036800
(everything else leave alone)
Screen on (balanced mode):
(leave CPU at 0)
CPU governor to interactive
max frequency to 2457600
(everything else leave alone)
You don't have to limit the CPU frequency, but I figured it would be the best way to maximize the benefits of powersave mode, not to mention restricting any apps to crank up the CPU while phone is sleeping.
I would not recommend using powersave mode normally. The phone will become very unresponsive. However, I am setting my phone to screen off setting if battery is between 0-15%. That may change to 10% if if ever becomes troublesome.
Here are all the different governor settings: http://tasker.dinglisch.net/userguide/en/cpu.html
So I just updated my OPO to 30O and now Tasker says the CPU option is not available one my device.
Anyone know what is going on? Is there another option to use?
[UPDATE] Oops, I lost root.
Bump! I want this too...
I've used this but i noticed battery drain.

hmm i consider if it's needed to use Tasker on Lollipop

What about having one profile to set the CPU to Balanced mode when the screen is on, and having an exit task to set it to powersave?
I think I'll try that, but maybe with a delay of a minute or two before running the exit task.

That's how I have it set up but my profile is screen off. powersave when off, exit task (screen on) is back to balanced. I do like your wait a minute after screen off idea. I just implemented that. Thanks!
Thanks, this is what I was looking for. But why only CPU 0, do we not have to repeat the same for CPU 1,2,3. I guess CPU number refers to respective cores.
And how much is tasker effecting the battery discharge being in background.
I had up and downs using Tasker to set CPU Governor, so ended up using Boeffla kernel which supports this kind of management natively as described in the FAQ page: http://www.boeffla-kernel.de/index.php/faq.
Boeffla kernel has both CM 11s and CM 12 versions, so you are covered whichever ROM you are running.
it is possible, but not with tasker!
i will write an app therefore
it's just a hour task or so, will upload it to the playstore later this week.
i don't know exactly but i think you need to be rooted, but maybe i'm wrong, will look into it later

Not sure what you mean about the scheduler. But the screen off and on is controlled by a new profile. Add a profile and select event, then display off. When display off is active, you select your powersave task. The exit action of display off profile, or screen on, should be activating the ondemand task, returning the device to full speed.
I did it like this to have one profile to control that one action. More efficient than two profiles, one for screen on and off.

Hi there! How do you set the 1 minute delay to start task?? Thanks
For example, i have it set to display off, governor battery saving and 1036800 max freq and min 300000 freq, but i want it to start the task about 1 min later, becouse sometimes rigth away we go tether again, for some reason...

GPU undervolting
Adjusted stock CPU & GPU governor thresholds for better performance
DoubleTap2Wake
Sweep2Sleep
init.d support
set_immutable binary removed from ramdisk for 4.4.2
Speed up system startup
Now more detail about some features:
Governors
PegasusQ
Governor from Samsung with hotplug support. Perhaps, the most tunable and flexible one.
Parameters description:
sampling_rate: the interval with which governor will be carried out. Less value - better responsiveness, but at the same time, more load for CPU by governor itself.
sampling_down_factor: amount of iterations governor will stay at highest frequency before go down.
up_threshold: load threshold in % above which CPU frequency will be increased.
up_threshold_at_min_freq, freq_for_responsiveness: at frequency lower than freq_for_responsiveness will be used up_threshold_at_min_freq threshold - provided for better responsiveness.
down_threshold: load threshold in % below which CPU frequency will be decreased.
freq_step: step of frequency encrease in % from maximum frequency.
hotplug_freq_*: high and low frequency thresholds for making decision about hotplug of each core.
For clarity, it looks like this:
Code:
static int hotplug_freq[4][2] = {
{0, 1596000},
{208000, 1795000},
{416000, 1996000},
{624000, 0}
};
In this array left column is frequency at which core will be disabled; right column - frequency at which will be enabled next core.
hotplug_rq_*: analogous parameters set (array), defining queue task length for making decision about hotplug of each core.
Code:
static int hotplug_rq[4][2] = {{0, 50}, {50, 100}, {100, 150}, {150, 0}};
For example, second core will be disabled after reaching 208MHz frequency and amount of tasks must be less than 50;
third core will be enabled after reaching 1795MHz frequency by second core and amount of tasks more than 100.
cpu_up_rate: amount of governor iterations cpu should stay at defined frequency for enabling next core.
cpu_down_rate: amount of governor iterations cpu should stay at defined frequency for disabling last active core.
down_differential: defines load in % which must be less than up_threshold to go to lower frequency.
hotplug_lock: lock amount of active cores.
min_cpu_lock: limits min value of enabled cores.
max_cpu_lock: limits max value of enabled cores.
up_nr_cpus: defines how many cores to enable at a time.
AbyssplugV2
Based on Conservative, has hotplug support. Pluses: pretty simple, hence doesn't load CPU by himself. Frequency increases sequentally, after reaching max frequency - enables next core. And vice versa. Minuses: often enables / disables cores (what in itself is energy intensive).
Distinctive parameters:
up_threshold_hotplug: load threshold in % above which will be enabled next core.
down_threshold_hotplug: load threshold in % below which will be disabled last active core.
boost: load threshold above which frequency will be increased through step (for exaample., from 208000 immediately on 624000)
Optdemand
Governor by Hisilicon, based on Ondemand. Backported from Honor 4X/4C. Distinctive feature is each frequency has its own thresholds to go to higher or lower frequency.
Distinctive parameters:
go_hispeed_load, hispeed_freq: after exceeding go_hispeed_load threshold, CPU goes immediately to hispeed_freq frequency.
up_thresholds, down_thresholds: above and below load thresholds for each frequency. For clarity:
Code:
static unsigned int operating_points[7][3] = {
/* kHz up_threshold down_threshold */
{208000, 60, 0},
{416000, 60, 30},
{624000, 70, 40},
{798000, 80, 50},
{1196000, 85, 50},
{1596000, 90, 60},
{1795000, 95, 70},
{1996000, 100, 80},
};
For example, for frequency 624MHz, if load will go below 30%, will be calculated new lower frequency according to new load value; if load will go above 70% - frequency will be increased.
boost: frequency will be increased to hispeed_freq
bostpulse_duration: duration of boost in microseconds.
Interactive
Google's gold standard governor. Updated to 3.4 kernel branch
Impulse
Based on Interactive governor. Good responsiveness.
USB Fast Charge
Increases charge current when connected to USB. It has sense only when connected to USB 3.0
Can be enabled by writing "1" into /sys/kernel/fast_charge/force_fast_charge file or by third party applications.
Disabled by default
Intelli-Plug
Hotplug driver for governors not supporting hotplug.
Activated and deactivated automatically depending on chosen governor.
Parameters are in /sys/module/intelli_plug/parameters
nr_possible_cores: max cores affected by driver.
nr_run_profile_sel: has several profiles :
0: balance default
1: performance
2: conservative
3: eco
4: eco extreme
screen_off_max: max frequency at screen off.
touch_boost_active: enables additional core at screen touch disabled by default
CPU undervolting
Undervolting values can be set for each frequency individually. Regulator has step 8mV starting from 700mV. I've got such stable values:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But you should start from higher values. I've made a test: CPU locked at frequency 1795MHz, RAR creates archive with 4 threads in 10 minutes. Average CPU temperature during this time was 56.124 degrees, with undervolting average temperature became 51.119 degrees. I.e. average temperature became lower for 5 degrees which means less power consumption.
Comparative graph:
GPU undervolting
Since I couldn't find any common used sysfs interface and applications supporting it, you can make it using script (see init.d spoiler).
My stable values are:
Code:
160: 860 -> 700
266: 860 -> 732
355: 876 -> 764
533: 956 -> 860
700: 1052 -> 924
But most probable, you will have troubles with such values, try to find suitable for your own.
3DMark Ice Storm Extreme showed average temperature decrease from 61.587 to 55.502 degrees.
Comparative grapth:
DoubleTap2Wake
Screen on by double tap on it. Has two parameters in /sys/android_touch
doubletap2wake: enables dt2w. Possible values are:
0: disabled default
1: active at all screen
2: active at top half
3: active at bottom half
4: active at navbar
dt2w_duration: Since I couldn't implement waking up device from deep sleep by irq from touch panel, so kernel doesn't go to deep sleep when dt2w is active, I added parameter defining how long dt2w stays active after screen off. After this duration dt2w becomes inactive and kernel can go into deep sleep.
Sweep2Sleep
Swipe on navbar for screen off. Can be enabled by writing "1" into /sys/android_touch/sweep2sleep file. Disabled by default.
s2s_length: swipe length in dots. By default, equal to 25% of screen width.
init.d
For executing scripts at startup, put them in /system/etc/init.d folder and set permissions to 0755
Several scripts examples (doubletap2wake, sweep2sleep, fast_charge, gpu_undervolting): View attachment scripts.rar
Scores
For correct governors switching I recommend to use Kernel Adiutor
It also lets to manage IO schedulers, TCP congestion, fast charge, CPU undervolting.
Requirements:
Unlocked bootloader
TWRP
Installation:
Just install zip-archive from TWRP

Updates:
31.10.2016
CVE-2016-5195 "Dirty COW" fixed.
Now CPU voltage values take effect right after frequency changes.
30.07.2016
Adjusted voltages for overclocked frequencies due to cases of appearing stability issues on some devices.
15.05.2016
Removed GPU undervolting applying at booting due to some users had stability issues. Now for GPU undervolting use init.d script individually.
Adjusted governor thresholds.
Reduced min online CPUs from 3 to 2 when screen is on for stock pwrctrl_hotplug governor.

Battery is better from stock kernel??
Version lollipop compatible?

Thank you so much! I've been waiting for ages for a kernel which isn't only for emui 2.3
I'd installed kernel 5.1.1 ktuned on my P7 B852 and it's continuously restarts. Anyone had a kernel stock for TWRP?
What is your preferred setting?
Mine:
GOVERNOR: Impulse
CPU : maximum frequency 1596mhx
I/O : fiops with 128kb readahead
INTELLIPLUG :disabled
I discovered that with Intelliplug enabled, my phone has some glitches.....
With the settings above i get 50-60% battery when i go home, 8-10 pm
What are your settings ?

Someone else tried it on P7?
Installed with cwm on B861. Working, but I see no difference.
@Kostyan_nsk kernel comes overclocked, when I try to select the default clock and start the cell with the standard clock is not, always coming back to overclock, so I went back to stock kernel
@roxkiller, just set "Apply on boot" in Kernel Adiutor after limiting max. cpu frequency and enable Kernel Adiutor in Startup Manager, so KA will aplly your settings after reboot.
And btw, if you didn't notice, cpu voltage at 1996MHz is the same as at 1795MHz, therefore I doubt that power consumption will noticably increase relatively to 1795Mhz frequency...
I have set the cpu undervolting according to your recommandation. Today , i received a message on whattsap , when i picked up the phone to read it, the phone was already rebooting. It enter the system but saying no root available !!!
Rebooted the phone again, all ok.

It is not a recommendation, it's just my stable values as "play around" point.
@Kostyan_nsk it would be possible to compile a version without overclock ? I and perhaps most people do not like under / overclock the device, just heating up ... or pack the kernel to the option selected remain in next boot?
Kostyan what are you settings?
Updated version and details in first post.

I really want to try it on my p7
As my memory serves me right, this issue was solved a few months ago. But you better have to ask P7 owners about it.
I thought the problem was solved for 720p but with 1080p there were still glitches?
720p never had glitches at all.
I am running the latest version of Pure Nexus, with the latesst version of the Elementalx Kernel. I have also installed the EX Kernel Manager. This is my first attempt at a custom kernel and it is working very well.
The only 'issue' I am having or the last hurtle I am trying to get over is the CPU throttling at low battery power. I haven't done extensive testing but in the small amount of testing I have done it seems that when the phone gets around 40%, the Max CPU speed reported in the EX Kernel Manager drops to 1958MHz, with all the cores still enabled. It will remain that way until I charge up the phone above approx 40%, and at that point it will go back to 28800MHz (max value).
I have tried this https://forum.xda-developers.com/nexus-6/development/mod-disable-throttling-battery-low-t3440814 but it doesn't seem to work for me.
Is there a way to achieve this through Elementalx itself. I believe if I change the CPU Gov. to Performance the CPU returns to its maximum value of 28800 MHz even under 40% but using the Elementalx Gov. yields such a good mix of performance and battery life I would rather keep it.
Any thoughts or suggestions welcome.
Thanks.
Just looking at it again...... I'm hitting a max CPU frequency of 1985 MHz earlier than expected. It has happened at 50% battery usage. I can also confirm that changing the Gov. to Performance will up the CPU to the expected, max, value of 2880MHz.
I have discovered a couple things..... First, throttling, from the posts I have read means ' Throttling is turning cores off at lower percentages and keeping frequencies down, not at regular.' So the issue that I am experiencing is not throttling entirely as I have all 4 cores working throughout the battery range. What I do have happening and want to resolve is the Max CPU value, in Ex Kernel Manager changing from 28800 MHz, which is the maximum CPU frequency I have set, to 1958 MHz when the device battery drops below approximately 45%. Second... Changing the CPU Gov., while the battery is under 40% (1958MHz), will increase the CPU frequency back to 28800MHz until the phone drops another battery percentage, which will trigger the underclock (1958Mhz).
EXKM - Tools- User Settings Navigate to file sys/devices/qcom,bcl.39/mode and set "disabled".
And, ofc, edit threshold (99) in thermal conf file.

Phone was at 43% and running at an underclocked speed of 1958 MHz. Made the changes in EXKM to the Mode file and enabled the 'Apply on Reboot'. Rebooted the phone. Once booted took a look at EXKM and the CPU speed was still underclocked at 1958 MHz. Check the Temp and it was at 45. Checked EXKM and the CPU temp threshold is set for 60. Didn't change the ofc value. I don't want to disable the thermal as I don't want to damage the hardware accidentally. I also couldn't find the value. It isn't in the Mode file. Where could I find that? Is the ofc file required as well to allow this method to work?
I will continue to tinker.
Thanks for the reply and your help.
ofc= of course. [emoji12]
For me, work ok, only edited thermal conf file (cpufreq, hotplug, gpu threshold 100 threshold clear 99). Please wait some time to.phone cooling down (sleep phone 10-15 minutes) and open EX Manager and see again. Sometimes does not change max freq value at the begining. At least, i had this situation.

Thanks for the reply. I'm getting closer. I am able to run at 28800 Mhz until 20% battery life and then it underclocks to 1958 MHz on all cores. This is definitely a step forward. Below are the three sections you referred to, CPUFreq, HotPlug, and GPU. This is the modified file. My understanding of what this configuration accomplishes is that at 5% battery power the CPU will throttle back (underclock) to conserve battery power. Unfortunately this isn't happening.... yet.
Any other ideas on why this isn't working as expected? Is there another part of the file that needs to be changed?
Also is there a resource that explains what each line in these files do? I couldn't locate one.
Thanks!

@monteie2016
I find your shamu thermal conf file a bit strange. I have a pure nexus and elementalx and it's not like that. All you need to edit in this file (with text editor) is set the thresholds to 100 a thresholds_clr at 99.
Thresholds is the battery percentage at which the throttling occurs (at 0% (100-thresholds))
Thresholds_clr is the battery percentage at which the throttling clear (at 1% (100-threshold_clr)).
In practice, this will never happen because in that time your device is already dead.
I will upload a screenhoot of EXKM dashboard to see max freq in my case when battery was bellow 20%. It's stay on 2.6 Ghz.
Can you also post the CPU, GPU, and hotplug values. I would like to see how yours is configured.
Thanks

Also, I have an older version of the elementalX 4.23 as you can see on screenshot (with july security patches) , because the PureNexus rom does not have august and september kernel patches.
Here is SS thermal conf:

Couple of things...... Above you are showing me a status from EXKM at 62% battery. I don't have and underclock issue anywhere between 100% and 20%. When the battery life drops below 20% is where I get the issue (Underclocks to 1958Mhz from 2880Mhz).

I should also mention that I have disabled BCL, /sys/devicds/qcom,bcl.39/mode and changed the value to disabled.
I have attached two images. One is the battery at less than 20% and what I am seeing for CPspeed (underclock) and the other is above 20%.
Off topic thoughts @monteie2016
What you had asked for was posted in the previous post. The additional information was provided additionally. But you jumped on the extra info. And not one time in this thread have you "thanked" (thumbs up) the only person who had been trying to help you.
I did thank nemanja066 for his post on 20th September 2017, 04:51 PM (thanks button in thread) and my reply on September 23rd had a thanks and a thumbs up.
Also is there a resource that explains what each line in these files do? I couldn't locate one.

Looks like a bug with the aroma installer. Try again with flashing kernel in recovery and then in aroma set max freq cpu to 3033MHz. After flashing, reduce the frequency to the desired one in EXKM. After that, it might be fine, and the freq can be reduced only due to the increase in temperature, which is quite OK. When the phone cools down, freq will go back to the old value. If all this fails, then I do not know what to do next.
