Decided to download V1.0 of this kernel due to the 1.5 (possible) battery issues. My first kernel download - Hopefully it'll give me some great battery life :D
[Nexus 4 Original Android Development] ibegary:
If you dont see any battery life improvement check on other things before you blame the Kernel. In my case, I had to get GSAM to see what was actually eating may battery. It took a day but I finally got it to be better.

In my case:

1) CPU spy was showing that the CPU was operating at a minimum 1026 regardless of what SetCPU and Trinity set. Had to use "No Frills" to keep it 384Mhz

2) The sleep timer widget I had kept the device awake using 384Mhz instead of deep sleep

3) Google Maps (Location Access) was waking the device up more times than I felt it should.

4) Disabled Cell Broadcast Settings (as a suggestion from another thread, but I may re-enable to see if battery life gets worse).

My tips after all this is to use CPU Spy to ensure your device is going in to deep sleep and use GSAM to see what apps are eating your battery.

Good luck! :highfive:
[Nexus 4 Original Android Development] GeneralRam:
Cheers mate! My battery life hasn't been bad - just not what I would like it to be! Just got myself Better Battery Stats at the moment but will look into those other apps. Noticed my Android OS battery % being a tad too high but been told that is from the maps so will look into Location History.

What does the original post mean by voltage and gamma interface. This is just a kernel, when I hear interface I think of a ui that runs like an app. What am I missing here?
[Nexus 4 Original Android Development] morfic:

Not every interface is a GUI

Giving access to kernel internals through sysfs files you can read from and write to is still a interface.

I still have this behaviour too. Experienced it on v6.0 as well, although on v6.5 it *seems* like it is more sporadic and happens less often. Running aokp official build 2. Not a big enough to force me to revert back to v5.5 though as it occurs less often than not.

It's been happening to me too. It's always been sporadic for me so never bothered me that much. Mostly a minor annoyance when I do the "double tap" because it lags, and it turns the screen off on the 2nd press because I didn't think the first one registered.

Do you use any kernel utility like trickster? Make sure you don't have the "Frequency Lock" option enabled as this will force the CPU to stick to the levels you indicated in the app.

Not sure if this is a matr1x or aokp issue, but the colors were perfect on aokp official build 2 (well, not perfect but behaved as expected {I do like them though after slight modification to rgb}). updating to build 3 gives a prominent blue tint (not immediately, but after a few minutes, which is weird on it's own) and I have to turn down the blue temp to about 220 to rid of this. (matr1x v6.5)

Maybe even has to do with the trickster mod app update as I updated right before flashing build 3.

My first time flashing Matr1x kernel. I have to say coming from a previous custom kernel, Matr1x offers improved battery performance with 3H screen time off 3G/data. To me, that's a huge boost as I could not get past 2.5H with stock and from the other dev. The colours were definitely darker and now that I flashed PA 3+ w/ Matr1x kernel, it's grown on me.

I don't need a reason to flash to a different kernel (yet). ;):angel:

Re: [KERNEL] *Matr1x* v6.5 | JB - 4.2/4.2.1

The issue is definitely caused by the trickster update, and this is acknowledged by the app dev, although he is quite busy at the moment. If I understand the issue correctly, the gamma controls in the app are incompatible with the PA gamma control interface implemented in this kernel (and a few others).

Luckily for me I did a titanium backup right before the update.

[Nexus 4 Original Android Development] bigmase521:
Re: [KERNEL] *Matr1x* v6.5 | JB - 4.2/4.2.1

Mathkid, have you thought any more about adding Max Active Cores to the kernel for like in Motley,Faux kernels? This would allow users to set to value to say 2, for battery savings when wanted, and back to 4 for performance.
[Nexus 4 Original Android Development] knapz:
how much battery savings are you getting by switching to 2 cores?
[Nexus 4 Original Android Development] bigmase521:
Re: [KERNEL] *Matr1x* v6.5 | JB - 4.2/4.2.1

Dunno, haven't tried it yet. Have been hoping MK would add it so we can find out. Might add even more to Matr1x's already stellar battery life as an option!
[Nexus 4 Original Android Development] cheech87:
Reboot the device and run the query again.

Yes, having a slow chip shouldn't really affect stability (w.r.t. undervolting). This is because a different voltage table is applied depending on which binned chip your phone has. Hence, the kernel's default voltage is 100 mv lower than the stock SLOW voltage table (if, in fact, you do have a SLOW chip).

---------- Post added at 10:50 AM ---------- Previous post was at 10:47 AM ----------

I would also be willing to try this. However, I suspect capping the max online cores to 2 might actually reduce battery life as it may inhibit "race to idle".
[Nexus 4 Original Android Development] bigmase521:
I thought about this myself, but considering the success folks running Faux seem to have with his Eco Mode (max 2 cores), I'd love to try it.

[Nexus 4 Original Android Development] cheech87:
If you already flashed a recent version of matr1x, a workaround is to just look up what voltage table is being applied against MK's source and imply your cpu bin from that. Navigate to sys/devices/system/cpu/cpufreq/vdd_table and compare vdd_levels to what is found here:
