Nice to see you here, mathkid. Wow, its been a while since I've posted to XDA.
[Nexus 4 Original Android Development] digweed4me:
Use CPU stats from Google play it will show u all the cores .all four not active all the time it will when it needs too or run quadrant you will see all the four cores hitting max.
[Nexus 4 Original Android Development] Nitroz:
Very true, not all cores run at the same time, they deactivate when there's less stress on the CPU. If you do a benchmark, it will activate all cores. Its very rare you'll need all cores for real-usage.

Yes, that seems to be common. You'll notice this device get warmer than basically any previous phone with a plastic back since glass is more heat conductive. I would not worry about it
[Nexus 4 Original Android Development] barondebxl:
I've reverted back to 1.0. 1.5 has some serious battery drain issues.

Edit: example, on 1.5, I noticed some drain last night but I wanted to give it a little more time so I charged it fully and took it off the charge this morning. Lost 4% in a min 30sec literally, not touching the phone and no apps running in the background. Then I reverted back to 1.0, battery and was at 93%, used tapa talk for more than 5 min and battery didn't move at all.

System Tuner does work well.
[Nexus 4 Original Android Development] morfic:
People can't flash Trinity over Franco without getting stuck on google logo either, as anykernel scripts inherit the ramdisk left behind by franco kernel, so you are probably right.
[Nexus 4 Original Android Development] tengen:
I can't seem to get the voltages tab to show up in SetCPU with this kernel - is this expected behavior? I've switched to System Tuner for the time being, but I prefer SetCPU's interface. Is this just something I'll have to live with?
[Nexus 4 Original Android Development] bigmase521:
I didn't get voltages in SetCPU either. System Tuner works now, and a new version of Trickster Mod will work (currently in beta) once it's updated. If you've purchased Faux's or the Franco's apps, I'm assuming (not tested) either of those would work as well.
[Nexus 4 Original Android Development] luke05dee:
mathkid95, do you think it will ever be possible to have a GPU and Ram UV interface please? As how much the cpu can be UV'd it could be very interesting how low the other parts of the system can go. Like on my int s3 and nexus 7, their GPU's can be both undervolted by quite a bit. It's just while the gpu is on heavy load, a gpu UV can have a noticeable possible effect on temp. :)
[Nexus 4 Original Android Development] Harsh:
Will kernel devs stop using mods in RAMDISK? Its too much to loose for little gains.

And @morfic I wanted to ask if you notice any big change between Google & Linaro in kernel. Also same question for 4.6 and 4.7 toolchain.

Which one you prefer to have stability? And does stability effect with change from 4.6 to 4.7 as later one is fairly new on google git.

And mathkid95, did you notice any extra drain when making very UV. When I go -120 UV i get best battery, for -160 I have my phone heat up more. And going further down makes it unstable/camera glitch/reboot.

Hows is it possible to have phone stable at -160 mV UV but bad battery than -120 mV UV?
[Nexus 4 Original Android Development] Zanr Zij:
Maybe your phone not stable @-160mv so system try to recovery from unexpected problem.

[Nexus 4 Original Android Development] barondebxl:
Now how the hell did you achieve that??!!??? That is impressive cause it looks like you really used the phone even though it was WiFi pretty much the whole day.
[Nexus 4 Original Android Development] tengen:
That's interesting. Could it be caused by some minor instability at -160 mV? Something that you might not notice while using but would force the system to do extra work?

Also - how long is it recommended to wait before drawing conclusions about battery usage?

[Nexus 4 Original Android Development] dcop7:
14.0 is the latest version.

What CPU govenors and I/o schedulers do you guys use again? Just want to make sure for best battery life and possibly performance. GPU govenor would be nice too
[Nexus 4 Original Android Development] CalculatedRisk:
Most use the interactive and wheatly cpu governors for best battery, and use simple or Ondemand for gpu. I/O schedulers are all over the place for people.

Hey guys!

I installed matrix v. 14 kernel with Mahdi ROM and enabled d2tw but I have a question: why the phone doesn't wake when I knock on edge of screen and it work only with the center? How can I make d2tw work with every part of the screen like in another kernels?

Thank you in advance :)
[Nexus 4 Original Android Development] HiM@L:
it is done that way so that while in pocket... it doesn't accidentally turn on and drain battery.....
[Nexus 4 Original Android Development] Ciao600:
Oh... This feature is really uncomfortable . Isn't there an option to disable it?
[Nexus 4 Original Android Development] HiM@L:
well you can turn off double tap feature entirely.
[Nexus 4 Original Android Development] ilyadan:
I just finished testing 2 other kernels, and back to matr1x. Had no sound problems with the other kernels. I still have the sound statter on matr1x when screen is off. I set max cpu at screen off to 1.3g, but the statter is there. Can't fix the sound.

Did anyone find a solution for this trouble?

P. S. I'm using the latest stock ROM (KTU84P) and Matr1x 14.0 kernel.
[Nexus 4 Original Android Development] imru07:
Try increasing the voltage☺
[Nexus 4 Original Android Development] ilyadan:
Bumped by 25mV to same values I used in other kernels (-50 from stock). Didn't help, same statter.
[Nexus 4 Original Android Development] imru07:
You mean you added -50 on top of stock matrix configuration?.....
[Nexus 4 Original Android Development] ilyadan:
No. Matrix default is -75mV undervolt. I added 25mV and now was at -50mV.

Before Kitkat I always been at -100mV without any problems. When I try other kernels, I undervolt to -50mV.

Now I added another 50mV so currently no undervolt at all. Will check if this helps and report tomorrow.
[Nexus 4 Original Android Development] badaas:
Have you tried setting minimum cores to 2?
[Nexus 4 Original Android Development] ilyadan:
No, as it will miss the whole point of low battery consumption and the main reason I love this kernel.

I still investigate this issue, but it seems unrelated to CPU voltage at all. Checking diferences with other kernels on user level.
[Nexus 4 Original Android Development] imru07:
Also check on screen off max frequency if you haven't yet....some ppl had to raise as hi as 1ghz
[Nexus 4 Original Android Development] ilyadan:
Thank you very much for your advice, I tried 1.3Ghz but it didn't help.

Am I the only one at this thread with this problem??? I personally know at least two other people with Matr1x kernel that have same problem. We all love this kernel too much and stick with it, but it's driving me crazy. Together we can solve it, I'm sure of that.
[Nexus 4 Original Android Development] hellsgod:
Some users have this problem on this kernel, some on other kernel... I know from hammerhead (N5) it could be solved with allowing a second core to come online during screen off. Do you have this stutters everywhere, or only if you travel?

hells
[Nexus 4 Original Android Development] ilyadan:
Thank you for your advice.

The sound corruption happens everywhere. It happens after phone been in deep sleep for a while. I tried few other kernels, including yours undervolted -75mV, and it's OK there. For 2 days no problems. When I get back to matrix, it happens even with stock voltage (+75mV from default matrix). So I'll stop playing with CPU voltage.

I will try 2 minimum on-line cores and report back. It takes a couple of days to check this issue though.:fingers-crossed:

I'll take this opportunity to thank all members for their support :)
[Nexus 4 Original Android Development] Almayce:
From my experience nothing works. You can only reduce it with higher lowest freq, disabling max screen off freq or setting it to 1512. Increasing voltages across the board also help a bit, but still if a kernel does this for you, you don't get rid of it. At least I haven't.
[Nexus 4 Original Android Development] ilyadan:
Well, setting minimum 2 cores online didn't help. The sound is actually stater also at phone being on.

Any more ideas?
[Nexus 4 Original Android Development] simmac:
Try using a alternative music player if the problem also occurs.

For me, I only experienced this problem with Google Play Music, but not with Spotify.

Gesendet von meinem Nexus 4 mit Tapatalk
[Nexus 4 Original Android Development] ilyadan:
I'll explain. The sound is disturbed when I get a call, SMS, talk using Skype etc... It's not related to any specific software. It happens only with this kernel, and was good before Kitkat. It happens randomly and I can't reproduce it when I want to.

The CPU voltage is not affecting, also min. cores set to 2.

Setting min. screen off to 1.5GHz + whitley governor minimizes stater to minimum, but it still present.

Any ideas will be welcome :)
[Nexus 4 Original Android Development] Almayce:
Well, I posted tips to reduce it. Also, poweramp causes the most trouble. It's bearable in other programs. It will not go away completely. Trust me I spent many hours solving this issue. I just want to put your mind at ease, because u look awful lot like me back in the day :D maybe it could be device specific, I'm no expert, but this is my experience.

Yes, you can use TricksterMod for nearly every kernel.

Doubletap2wake stops working for awhile, so I have to tap a lot of times then it start working again. Have you noticed this? Looks like the dt2wake feature "sleeps". All I can think is greenify doing something to save battery and disabling this feature.

Other thing is that the dt2wake doesn't work when I turn on the phone, only after I wake with the power button first.

I used Trickster MOD to activate it.

I get the same issues where I have to double tap repeatedly to get the phone to turn on. I use Greenify and Trickster Mod too (I have not greenified Trickster Mod). I've tried different Max Screen off frequencies and the problem still occurs. I have also tried different CPU governors. I think that may help as now use interactive instead of wheatley as the issue with DT2WAKE seems to occur more when using wheatley.

I've also found that to play Google play music with the screen off without stuttering you it helps if set the Max Screen Off Frequency 594MHz or higher.
