No I'm not going lower with the UV. It will stay at -100. I mean the minimum voltage for voltage control interface.

Hello there,

first of all let me tell you that you made the best kernel for nexus 4!!! i dont know a lot about this stuff, i'm pretty new to this but i have tried every kernel possible available on this forum and i think yours is the best by far far far, so huge congrats there. As for UV limit and everything, everyone wants a bit of this and a bit of that, well i'm telling you, do things like you feel, we should be already super thankfull for the effort and work done to help us.

To tell the truth i have tried trinity kernel and i got 19.258 at antutu and with yours 18.222 max but hell what do we actually care about this duh!!! not to mention after 2 days of trinity kernel, my phone died suddenly watching a youtube video. Google sending me replacement. My bad trying to change from your kernel!!!! big lesson learned here... Anyway all this post to ask you just one question, I have read that the xiaomi mi2 has same exact hardware, but with the special ROM MUI this phone goes way smoother and score antutu more than 22K easily so i was wondering, is there a way for you to port this kernel on nexus 4 and mix it with yours to get the killer kernel above all???

Thanks for consideration, regards.
[Nexus 4 Original Android Development] undercover:
What you guys don't understand that having lower uv limit doesn't change anything for anyone. It only allows one to go lower with UV shall they choose to. I'm glad it's coming, and if it's unstable, well, I'll just go higher, but I'm happy to have that option. If you don't need it, don't use it. Simples.
[Nexus 4 Original Android Development] ctfrommn:
Are people stable at 700mv? Up to what frequency? Mine wont tollerate less than 725mv at 384 and needs more like 750 above that.
[Nexus 4 Original Android Development] bigmase521:
+10

700mV stable @ 384 here. My chip reports that it's "nominal" but I don't believe it. Frankly, I think it needs to have more self esteem :p
[Nexus 4 Original Android Development] Nshih422:
I understand why he wouldn't want to go lower right now. It will probably cause more "My phone is rebooting and I don't know why posts", or "how to do I get to the lowest voltage, my phone just reboots", etc. It seems that you convinced him pretty easily though so :good: :D

I don't UV because I haven't had time to sit down and find a stable UV table for my phone yet so this feature to me is irrelevant, at least right now. The rest of the kernel, performance and battery life, are unbeatable.

PS. Undercover, I am quite fond of the quote you have in your sig. It made me :) when I saw it. I'm stealing it for use on my social networks.
[Nexus 4 Original Android Development] undercover:
Feel free. :)

Words of a genius deserve to be spread.

Re UV. It's amazing by how much our CPU is obervolted. No wonder bastard runs hot. You'll see some amazing cpu temps when you start playing with it.
[Nexus 4 Original Android Development] eep2378:
I hate obervolting! ;)
[Nexus 4 Original Android Development] Vangelis13:
You have it all wrong: it's übervolting! ;)
[Nexus 4 Original Android Development] ctfrommn:
Anyone having issues with cores not offlining? I flashed and all 4 just sat at 384. I left it like that for a while (2-3 min) and they were still staying like that.
[Nexus 4 Original Android Development] tengen:
For me, it wasn't artifacts in the picture. Instead, my camera app would suddenly lock up after about 10 seconds and crash if I tried to take a picture after the lockup. Bumped the voltage up 12.5 and it's fine now.
[Nexus 4 Original Android Development] chappy824:
What rom are you on? If its cm then we know about the problem and are trying to fix.
[Nexus 4 Original Android Development] ctfrommn:
Nope....CFX.
[Nexus 4 Original Android Development] chappy824:
Weird...this isn't a problem on other aosp ROMs. Can you flash stock kernel then flash matr1x again to see if it still happens.
[Nexus 4 Original Android Development] ctfrommn:
I can....
[Nexus 4 Original Android Development] Haomuch:
Tested the 3.5 kernel but the msm_hsic_host wakelock doesn't improve at all
[Nexus 4 Original Android Development] undercover:
Because it's related to radio. I guess it will be the same until Google does something about it.
[Nexus 4 Original Android Development] ctfrommn:
Nada...still the same. disappointing as I wanted to try this new kernel.

How do I download 3.0? I don't see it on the download list anymore.
[Nexus 4 Original Android Development] yym789:
I went back to 3.0 from 3.5.

I think 3.0 version is an amazing version for battery.:p
[Nexus 4 Original Android Development] m_zet:
How long did you spent on 3.5 to come up to this conclusion?
[Nexus 4 Original Android Development] yym789:
only 1 day. I never install new app and use it as before.

If I use 3.0, the battery only spend 3-6% for 8 hours sleeping time. For 3.5, at least 10% - 12%.
[Nexus 4 Original Android Development] chappy824:
After settling in I'm getting great battery life...5 1/2 to 6 hrs on screen time and lasts over a day. V.3.5 is the best to date IMO.
[Nexus 4 Original Android Development] eep2378:
You need at least 3 full charge cycles before you can make a verdict on battery life.

[Nexus 4 Original Android Development] noneabove:
Two questions, what's special about the CM version? Do you work on that one to allow particular tweaks done in CM that rely on kernel to work? Also what app can I use to control kernel? With all of faux's changes does his app work well or should I just use system tuner?
[Nexus 4 Original Android Development] chappy824:
Cm devs do things different so kernel devs have to make some changes to make it compatible. I use system tuner for changing voltages and no frills for CPU.
[Nexus 4 Original Android Development] noneabove:
That's what I figured with the CM kernel, so if they make a change to their ROM that has kernel reliance, i'll be fine since he has a CM specific version? Just wondering since most other people only have one version. Of course I would wait for him to update his kernel before updating the CM nightly :P There was just a comment made from a CM dev a few days ago where he mentioned some custom Kernels may break some compatibility so I was a little concerned with hearing that
[Nexus 4 Original Android Development] chappy824:
Yeah there are definitely issues with compatibility... This latest version is not playing nice. Matr1x with any aosp ROM is fantastic though. Hopefully these minor bugs can be straightened out sooner or later.
[Nexus 4 Original Android Development] MattyPW:
Is PA 2.99 based on CM??
[Nexus 4 Original Android Development] noneabove:
Dam.. I wish CM wasn't the most stable featurefull and most promising of future development ROM :( I want to try out these kernels for their benefits (i only got 4 hours screen on time today while some people here got 7?!?!) but afraid of like you said, it not playing nicely :(

Do you know if it works well with rasbean? What're you running?

Side note, does CM incompatibility explain no better than average battery life on any kernel?
[Nexus 4 Original Android Development] chappy824:
I'm running rasbean and its the best yet!

Oh quick question then about rasbean, slightly OT from this kernel but what the hell, do the quick setting tiles work like in stock or in CM (in CM they're toggle on click, open settings on long press)
[Nexus 4 Original Android Development] chappy824:
Its aosp based

---------- Post added at 10:20 PM ---------- Previous post was at 10:18 PM ----------

They work like stock ones. Its not that bad though because rasbean is so smooth and runs perfect with mathkids kernels.
[Nexus 4 Original Android Development] noneabove:
Okay okay you've convinced me I'll give it a shot ;P Hmm.. Time to titanium back up all my ****! Hopefully I don't lose stability from doing that, it used to on my Desire Z, do you know if it'll be a problem on an advanced device like the Nexus 4?
[Nexus 4 Original Android Development] Vangelis13:
Don't install system app & data backups, you'll be fine.
[Nexus 4 Original Android Development] DowntownJeffBrown:
I love rasbean its the best like butter all over my screen and that's saying something considering how smooth all of the N4 ROMs are.

I've been using titanium backup and it works great. Just one suggestion only restore the app not app+data.
[Nexus 4 Original Android Development] noneabove:
Oh not data ? for any of the apps? Dam was hoping to do that for games haha
[Nexus 4 Original Android Development] Vangelis13:
Not for system apps, all other apps you can.

Sweet kernel you got here. Much thanks. Running it as is, no additional undervolting.

Last night I left my phone plugged in to the USB port on my laptop to slowly charge. Woke up this morning to see that my phone had seemingly un-charged, dropping from 80% to 45% overnight, despite being in a charging state. Was on wifi all night. Normal passive drain is about 1% per hour or less, so I don't know what's going on.

Not sure if this has anything to do with the kernel at all, or if it's some weird error on my part. I'm currently running stock rooted 4.2.1 with matr1x 3.0. Had no other problems so far; the kernel's been amazing.

Oh, I wasn't accusing the dev; just reporting the issue in case it was a bug. The strange part is that battery drain was fine before I went to bed, so unless an app suddenly started acting up after I went to sleep, I don't think a rogue app was the issue.

I'm using gsam battery monitor, but unfortunately it didn't record any useful app data since the phone was in a charging state.

I agree. I don't like this feature because it can't be disabled for people who want to charge completely. That is at least, from what I read from ezekials thread. It can't be set past 96%. I'd rather it charge to 100.

BUGFIX #2:

The charging limit is set to 96 by default which will mimic the behaviour of the stock kernel. Also, the maximum value accepted by 'charging_limit' is set to 96.

So for people that are having problems or ones that are going to try matr1x, 98% of ROMs available are aosp based. If its cm official or unofficial cm or cm jellybro kangs you should flash cm version of matr1x. All others should flash non cm version: Aokp, pa,stock,rasbean jelly and on and on....

If you are coming from another kernel it is advised that you flash a reset kernel or "stock mako kernel" boot into the ROM....then back to recovery to flash matr1x. :)
