Screen off that low is just asking for trouble with no benefit .
[Nexus 5 Original Android Development] nunoleite46:
so far without problems, do not need to 1.2GHz when the display is off.

[MENTION=4684315]flar2[/MENTION] I'm not sure if this a bug or what mate.

But since the earlier EX app i haven't been able make the screen off limit stick, by default it is 1.2, i would like to change it 960 MHz, but when i select it and tap the "set on boot" icon and reboot, the Max Screen Off is reverted back to the default. I don't think the ROM would be the problem but I'm Running Cataclsym.

Maybe you can advise me on why this is happening? Thank you.
[Nexus 5 Original Android Development] tcat007:
Changed my screen off to 960 and seems to stick. Using Kernel Adiutor and Chroma. Just switched from Code Blue and feels just as good. Battery seems to be draining a bit faster, but I need to give it a couple days to officially comment.
[Nexus 5 Original Android Development] flar2:
I just rebooted about five times and found that the setting does apply, but if you set it lower than 1267 and happen to be touching the screen at the moment the setting is applied, it will be set to the touch boost frequency.
[Nexus 5 Original Android Development] LiamAtkins90:
I will try that now thank you.
[Nexus 5 Original Android Development] flar2:
Careful using kernel adiutor, it doesn't have all the settings for EX and does something to permissions on cpu freqs that can cause problems.
[Nexus 5 Original Android Development] tcat007:
Just switched to Trickster, all is well.
[Nexus 5 Original Android Development] slmklc:
just a noob question, I want to use color profiles but don't know will using them make games laggy etc ? I mean will using color profile putting extra stress on cpu/gpu ? and battery drain wise ?
[Nexus 5 Original Android Development] mrro82:
I've always had mine set at 300 with screen off and haven't had any issues. Notifications, calls, everything still comes through. YMMV though.
[Nexus 5 Original Android Development] drawde40599:
There is no added benefit having that low , your actually doing the opposite of what your trying to accomplish .
[Nexus 5 Original Android Development] mrro82:
How is it opposite?
[Nexus 5 Original Android Development] cocchiararo:
i remember something about it taking too long for stuff to complete with the screen off, wich resulted in more time [MENTION=1785406]300m[/MENTION]hz, instead of little [MENTION=1206410]higher[/MENTION] freq, and then more time in deep sleep.-
[Nexus 5 Original Android Development] Hatshipuh:
Instead of using higher frequencies, finishing the task quickly and going back to deep sleep (race to sleep), with low freqs you keep the device longer awake, resulting in more energy usage compared to higher freqs.
[Nexus 5 Original Android Development] mrro82:
Ok. I'll give it a whirl. I'll set it to 1096 and see what my battery does. Not saying you're wrong at all. Just like to see what my apps and settings do with it ramped up.
[Nexus 5 Original Android Development] flar2:
Just be careful your min freq doesn't get locked at 1267 with trickster.
[Nexus 5 Original Android Development] tcat007:
Seems to be sticking. Can that min. be set lower?
[Nexus 5 Original Android Development] walpurgisnacht30:
People really loves to playing around with frequencies, yet when they have a problem with it they'll simply blame the kernel lol
[Nexus 5 Original Android Development] magnamentis:
seconding that my friend, so true unfortunately :)

have a good time :good:
[Nexus 5 Original Android Development] slmklc:
anyone ?
[Nexus 5 Original Android Development] zerosum0:
I'm having issues with the app, when using power save. When I take it off the max frequency is 15##.no matter what I do it take an age before I can get it set at max again. Also during charging the phone gets really hot, 85c plus. Running stock rom and have used EX for the last year. I've had the max frequency problem with the last few kernels. I just cant set the highest 2 frequencys often. The heat issue started with the latest kernel. Ive turned fast charge off and set up the cooler setting but it was 85°C today! Hate to moan about this as I love the kernel and app. By the way when I update the kernel I normally get you a coffe. Does all the money from the donation go to you, or do Google grab some??
[Nexus 5 Original Android Development] magnamentis:
ok, the answer is no but you could as well choose a profile and play your game and you'd know how it behaves in your specific environment, that's probably what many thought and why there was no reply earlier ;)
[Nexus 5 Original Android Development] slmklc:
I already tried it with game "relic run" seems a bit laggy for me after applying a color profile but I am newbie to android you know :)
[Nexus 5 Original Android Development] Midomad:
Regarding color profiles,

What profile are you using guys with EX?
[Nexus 5 Original Android Development] magnamentis:
cooler colors, it's not a profile but a feature. hassle free and a close to perfect amoled imitation when it comes to brighness and whites not being yellowish. ;)

OMG battery drain on cm12.1!
[Nexus 5 Original Android Development] flar2:
Battery drain is never the kernel.
[Nexus 5 Original Android Development] AndresOrue:
Use better battery stat, use greenify and use wake lock detector to see where the problem really is ...

I am Using default setting and I never had a problem

Don't hate what you don't understand

[Nexus 5 Original Android Development] Chirag7:
[MENTION=4684315]flar2[/MENTION] can you add the power aware cpu scheduling feature and partial-resume from Electroactive Kernel? I've been using the latest release thanks to [MENTION=6008473]Electrex[/MENTION] and my battery life has improved greatly due to the cpu scheduling improvement. android system now uses much less battery when I checked the battery stats in settings. It would be a great feature for your kernel.

Cheers!
[Nexus 5 Original Android Development] tylerdurden83:
No offence taken man, but you are overly on the defensive side. I've seen you post countless times how this is stock, how that is userspace, without really any evidence.

I've just reported a KERNEL issue on the N10 forum that caused the device to never enter deep sleep: http://xdaforums.com/showthread.php?t=2778248&page=95

So absolute sentences like yours that I'm quoting make me laugh, battery drain can EASILY be caused by the kernel.
[Nexus 5 Original Android Development] y0nigt:
I'm on latest cataclysm, using the latest version of the old ex kernel manager.

My second core is stuck at 1267MHz@idle since updating to 4.02.

I've tried:

Resetting the kernel app

All available CPU governors

mp-decision on/off

various screen off frequencies
[Nexus 5 Original Android Development] sjknight413:
False, what you've reported there is a bug that has a side effect of battery drain because it keeps the device awake. Kernels can have bugs yes but what flar2 is saying is that the kernel is never the cause of miscellaneous battery drain that just happens. There are no bugs in this kernel, nothing preventing the device from entering deep sleep, nothing making cores stick at high frequencies, therefore no battery drain.

Get over yourself.
[Nexus 5 Original Android Development] tylerdurden83:
Lol, get over myself? I simply stated a fact, which you magically transformed into a lie.

Did Khaon's kernel cause the rom/device/tablet/whatever it was paired with to not enter deep sleep? Yes / no answer, no bs excuses.

Would changing Rom and keeping the same kernel resolve the issue, since <quote>Battery drain is never the kernel.<unquote>? Yes / no answer, no bs excuses.

If you wanna state that THIS kernel is working properly, I have no problem with that, but saying that "Battery drain is never the kernel." is as retarded and false as saying that dogs can fly.
[Nexus 5 Original Android Development] GS2Giova:
I have a gmail drain never had on cm12.1 kernel..I'm sure it's not fault of your kernel but it looks so weird!
[Nexus 5 Original Android Development] flar2:
I been doing this for a long time and know exactly what I'm doing. I've answered many thousands of questions and can say with confidence when something is or isn't a problem of the kernel.
[Nexus 5 Original Android Development] tcat007:
I get 4 hrs SOT, this build, previous build, Code Blue. Only time I see a battery hit is some app gets stuck doing something it shouldn't, or I turn on cell service where there is no cell service. This kernel feels as good as CB, so this is what I use now. Default settings with -50 uv.
[Nexus 5 Original Android Development] jaibar:
Just for curiosity, what do you achieve by undervolting by 50mV?
[Nexus 5 Original Android Development] cocchiararo:
IF the SoC can operate at a lower voltage without crashing, he gets lower temps and lower battery use.
[Nexus 5 Original Android Development] parkson:
Decreases heat, helps stability, improved battery life (marginal)
[Nexus 5 Original Android Development] jaibar:
I think it is an urban legend. Except the improved battery life being marginal, which is true.

For most people UV results in more instability, "freeze of death" and all that.
[Nexus 5 Original Android Development] DroidIt!:
Well, I've been uv'ing by 25 global for probably years and never had any instability. If you do it and do have instabilities just back it off a bit. So, I think there might be some truth that it MAY cause instabilities, but I've personally never had any.
[Nexus 5 Original Android Development] walpurgisnacht30:
Screen of death and random reboot are often caused by undervolting, so it's not helping stability at all.
[Nexus 5 Original Android Development] Stryder5:
I can see your point about how battery drain can be caused by A kernel. But the post in this thread refers to THIS kernel. It sounds like OP is pretty certain of his work, and that battery drain shouldn't be caused by THIS kernel.

In any case, just flashed 4.02 yesterday so looking forward to see how it performs :)
[Nexus 5 Original Android Development] tcat007:
Actually now that I looked, I am only 25 uv, but normally go 50, mainly for battery. Never had any issues on Chroma (or Purity). I had checked benchmark yesterday at -25, tested today at none and got an extra 900 performance. I prefer saving battery to performance (unless something lags), so far fast and smooth at -25.
[Nexus 5 Original Android Development] Balino:
I have a strange problem with the M version. When I change something in the graphic option in ex kernel manager, frequency of one core get stuck at 1267mhz, instead resetting everything to default solves the problem. By "change something" I mean everything, like change min GPU freq or the GPU governor from ondemand to performance. Try it yourself. Running stock factory image of course.

Ah i forgot, it happens with mpdecision and custom hotplug aswell

[Nexus 5 Original Android Development] menting:
Not an urban legend.

As with any chip based on transistors, every chip has a spec voltage range that it can operate correctly in ( I think it's usually +/-1.5%-3% nominal voltage with recent process nodes), and they will be tested to that spec before it gets sent out to be packaged up. Besides the spec voltage range, each chip also has an inherent voltage range that it can operate correctly in (will be same or greater than the spec voltage range), depending on PVT corners the chip is at.

If you go over that spec or under that spec, there's no guarantee of correct operation, but some chips can handle it if they are a faster silicon, and thus have more margin on the low voltage end.
[Nexus 5 Original Android Development] dechronic:
Sounds reasonable as I have seen people able to under volt and be stable with lower voltage than mine, which may not even boot with the same settings.
[Nexus 5 Original Android Development] Zidane23:
Same results here. Can you consider this feature?
[Nexus 5 Original Android Development] Neverendingxsin:
Just installed the kernel last night on SOKP (which is now AOSP) and had a hiccup today. Screen froze and black screened, only thing I was able to do was get to the reboot menu and reboot or hold down the power button to reset. Any idea what could cause this? Can't remember for the life of me the easiest way to get a log while out and about.

How to disable the power button

Hi, a friend of mine is running this kernel on his nexus n5 and would to disable the power button. Is there a funtion built in that would let you do that? If so, would please share 'how to' with screenshots. Thanks
[Nexus 5 Original Android Development] :
Try flashing permissive.zip
[Nexus 5 Original Android Development] Neverendingxsin:
Will that mess up anything if it's not needed? The phone booted up fine and worked all day yesterday, had the first reboot today.
[Nexus 5 Original Android Development] drawde40599:
No won't mess anything up , but I wouldn't do it unless that roms OP says you need it . If it was just a one time thing I wouldn't worry about it . If it keeps happening then you would need to post a log
[Nexus 5 Original Android Development] dioxide95:
Does this Kernel support Multicore Power Saving (as shown in TricksterMod) ?

Also, what will be the effect on my phone if I change the min frequency as well as max screen off frequency to 300MHz?
[Nexus 5 Original Android Development] MrKaon:
I take it back, 4.0.2 has no problem regarding lag.

Thanks
[Nexus 5 Original Android Development] Neverendingxsin:
Easiest way to get a log while out and about? Usually doesn't happen when i'm near my PC.
[Nexus 5 Original Android Development] drawde40599:
If you own the app just go to tools tab there's a option to pull log for you .

If not use your file Explorer go to

cat /proc/last_kmsg & sys/fs/pstore/console-ramoops
[Nexus 5 Original Android Development] Wibin:
Sadly this does not appear to work for me. As far as I can see, the system interface doesn't exist. Dead-end after subsystem. ElementalX the only one with this voltage limitation support? Any thoughts? :eek:
[Nexus 5 Original Android Development] Neverendingxsin:
Just bought the application, I assume when it happens again after it reboots just hit the "Last Kernel Log" button and then upload that for someone to look into?
[Nexus 5 Original Android Development] drawde40599:
Yep . It will pull the log and put it on your SD . Then just post it here attach flar2 to it .
[Nexus 5 Original Android Development] Neverendingxsin:
And like clockwork it happened again, good thing I grabbed the app.

https://drive.google.com/file/d/0Bx4sftkd1mSvV3BlV3pGVThCZ3c/view?usp=sharing

That's the link for the log, just a bit of info, phone was idle at the time, went to check it and the screen lit up but it wouldn't show the lockscreen or anything. Was able to hold down the power button and hit reboot but that was about it.

Changing scheduler back to cfq seemed to have helped in the micro stutters when scrolling through some apps.
[Nexus 5 Original Android Development] DoesntPostAThing:
I don't know, ever since I stopped caring about the stutters (as an experiment), they've gone away. Now only when I'm looking for stutters so they appear. So just forget about it, use default settings, and enjoy. BTW, not sure what you did, but I've never had Riptide play so smooth.

Also, I was able to get 015 to "stutter" by accidentally thinking I had flashed 019, and then everything was slow. On the other hand, I once accidentally flashed 019.1 thinking I had flashed 015 and things were faster than ever. I then flashed stock kernel and everything was slow. A day ago I flashed stock kernel and it was smooth. So I'm guessing it all depends on how you think. What you think is what you get.

Sent from my Nexus 5
[Nexus 5 Original Android Development] letmedanz:
I think that helps as well.

The stutters were very minimal, but you could notice if you paid attention.

i changed to cfq & rebooted and can see a difference..
[Nexus 5 Original Android Development] DoesntPostAThing:
May I suggest something? Don't "pay attention". Looking very hard for something that might or might not exist is causing your brain to think that they do exist. Instead, relax, and use your phone naturally. Also, the cfq might be "counter-placebo" as well. You think it's smoother because a dev said it may help fix a "non-existent" issue. I was there, looking at every frame drop, but after a day decided to just screw it. Phone is much "smoother" now. I'm on fiops btw.
[Nexus 5 Original Android Development] letmedanz:
Lol.. True.

I do hope the fact that the phone seems smoother is not placebo..
[Nexus 5 Original Android Development] :
Dumbest thing I've ever heard!

It's not in my head I'm sure of it, you just keep ignoring it I'll use a version where the issue doesn't exist, that 'it's your imagination' stuff doesn't help development of this kernel

I'll check again when flar2 updates
[Nexus 5 Original Android Development] DoesntPostAThing:
What I'm saying is that there is no issue to begin with, we were all probably still paranoid of stutters since 018. Flar likely reverted what was causing it already so there's no logical reason for stutters to occur now.
[Nexus 5 Original Android Development] epithetic:
Scrolling in applications is fine generally. From what I've seen stutter tends to be most noticeable after waking from deep sleep or periods of inactivity (a somewhat reproducible method to elicit stutter is to wake the device and keep opening/closing app drawer and/or scrolling in the app drawer).

Did some testing with .20 and it seems noticeably better although not completely eliminated. Curiously, setting the GPU governor to simple on elementalX gov does eliminate stutter issues as has been pointed out (while CPU response looks to be similar) and is undistinguishable from ondemand governor/stock settings.
[Nexus 5 Original Android Development] :
I wasn't even aware there was a problem until I experienced it, I first used this kernel a couple days ago, came from Bricked and noticed its smooth but on home screen it stutters once in awhile, like irritating stutter not slight I can ignore kind, I flashed back to Bricked its not there, I flashed 0.19 its there, flashed Bricked its gone, flash Faux its not there, I flash stock kernel and rename mpdesicion.bck to mpdecision and thermal-engine-hh_bck to thermal-engine-hh to remove Bricked stuff and then boot system and flash Elemental everytime so that's not the issue, after back and forth for past two days I just flashed 0.15 and its perfect, no annoying stutter and yes scheduler is cfq as flar2 pointed out.

TL;DR version

Its not in my head, not placebo, the stutter is there, and I flashed stock image again just to be sure, after all that effort last thing I wanna hear is some theory that its an illusion

BTW I always use ondemand for GPU and CPU
[Nexus 5 Original Android Development] DoesntPostAThing:
I don't know, stock was nowhere near as smooth as 020 for me. Faux was even more stuttery than stock. Which version did you first notice the stutters on?
[Nexus 5 Original Android Development] AhmedFaiz:
I am having micro lags while scrolling tapatalk which is not there for me on 0.19. Flashed all default settings for 0.20. Going back to .19 for now which is working rock solid and smooth.

Nexus5/PA4.0beta/ElementalX 0.20
[Nexus 5 Original Android Development] :
It was on 0.18 and I was using Slimkat 1.95 and Nova launcher at the time, got really pissed..... explained previous post.

I most easily notice the stutter if I do something in another app and go to home screen and scroll back and forth like you would when searching for a shortcut there and bam stutter

As I said issue is solved for now on 0.15 so I'm happy that I have a smooth and customisable kernel with great colors and faux sound, was actually looking for a mpdecision kernel and Elemental fit my needs completely thanks flar2
[Nexus 5 Original Android Development] nealkoy:
Have you tried using show-p bricked_uninstall.zip instead of renaming the two files? Maybe it helps for a cleaner installation later on.
[Nexus 5 Original Android Development] flar2:
If you have annoying or noticeable stutter, there has to be something else going on with your phone. Because I have no stutter at all with any version.

I thought we were talking about minor occasional stutter in the app drawer.

Yup noticeable stutter in home screen in certain situations not all the time, and 0.15 fixed it, so something changed between then and now that's causing it on my phone and others

Agree , I can't make this kernel stutter if I wanted to , 19-20 have been great . ran 20 yesterday 2 cores OC at "2400" step , and simple GPU gov , cool colors ( brightness 50%) . first charge pulled 3.3 hours screen on time , with EVERYTHING turned on 24/7 , GPS , google now , sync, WiFi, and Everything else Google that can run . I'm not a battery guy at all but just wanted to see being new to this kernel and that's pretty impressive for MY use.
