Maybe either keep it or remove it for next version for some blind testing to see

[Nexus 4 Original Android Development] iscraigh:
I am trying to understand the big advantage to undervolting with electronics.

In the real world higher voltage equals less draw over the same wire, OHMs law. I will run something at a higher voltage to combat the resistance and still arrive at my endpoint with sufficient voltage to do the job at hand.

In my job if I run at a higher voltage I reduce my draw and increase my standby battery life. The increase in battery life is very dependent on the resistance of the cable I am using. If I am using a large cable then I see only a small difference but if I am using a small cable I can gain battery life. Generally speaking higher voltages are more efficient over distance. If I operate a device at a higher voltage it will draw less amperage, lower voltage more amperage to do the same work. Resistance would not seem to be a big factor in electronics. What I am asking is if I hit a chip with lower voltage would the amperage not just increase? If so the net gain on battery life should be nil. If not why does ohms law not apply. Thinking about this even more a lower voltage/higher amperage should produce more heat, lower voltage = more resistance the byproduct of which is more heat.

Again I deal in ac volts and very long runs of wire and am by no means claiming any expertise, I may be applying ohm law incorrectly, so please enlighten me, I am sure someone here has the answer.

Re: [KERNEL][GPL][N4] franco.Kernel - r86

I am well aware if I leave the settings open it will go back to that but if it was not open in the first place why should it open to it when I unlock the phone, never happened before and now it has and the kernel is the only thing I have ever flashed so it could well be related hence the question

[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
I posted my lengthy post as a study. I'm not saying to put them back. I noticed msm wakelocks disappear, but I was reporting that my battery usage is roughly the same on an hourly basis.

Sure from a wakelock perspective I love seeing the figure go down, and so I need to drill more into why my battery life hasn't significantly changed.

It's these posts that get to me. 1.3% to 2.2%. Is that statistically significant? What's normal usage variance? I saw my battery use per hour change from 5.8 to 5.5 moving from r85 to r86. If it helped it helped very little. That's not saying I don't appreciate franco's work, I do. I love the guy, but it doesn't mean that one little change is going to give you 5 hours of extra battery.
[Nexus 4 Original Android Development] halluci293:
It's been a while since I've learned/used it, but isn't Ohm's law V=IR? So higher voltage is higher current at same resistance?

In any case I think the relevant factor here is power. Heat is proportional to power, P=IV, so lowering voltage lowers power, all other things constant.

But these are just the basic equations I remember from physics and I can't claim to have any sort of knowledge about how silicon chips work.

Edit: Well, since you got me curious about the topic: http://en.wikipedia.org/wiki/Dynamic_voltage_scaling

Essentially, capacitance charges faster the higher the voltages applied, so the chip can keep up with higher frequency operation more easily. Decreasing voltages increase time for capacitance to charge, but since power dissipation by the chip is proportional to voltage squared times chip frequency times capacitance, undervolting is great for reducing temperatures.

Stock Screen Color Values

First time Franco Kernel user. Been searching and reading about the color values of this kernel. It does look slightly different to me than stock CM10.1 colors. Does anyone know if any gamma or color changes are made vs stock colors that can be adjusted in the Franco App?

Edit: If the values are changed in the Franco App and then I hit default values, it seemed to be a little bit different than the stock colors after a reboot. It is 1:30AM and I may be going crazy lol.
[Nexus 4 Original Android Development] dhruvmalik:
I think they have been changed within the Kernel. Somehow it looks different than CM10.1 standard. After flashing Franco, its got a better brighter cooler colors.

The only Issue I am having now and I think its a 4.2.2 issue is that my Signal is fluctuating drastically and switching dropping 3G (H / H+) more often while before in the same locations it didnt. Its everywhere, not just my home.

Does anyone know if its a known issue?

Before on 4.2.1, 3G was strong, now I could see it dance around.

Vodafone India is not experiencing any issues, so its not them.

My SGS 3 is full bars while my N4 dances its Signal bars.

EDIT: Running CM10.1 Feb 22nd nightly. Franco r86, .48 Radio and newest bootloader.

Had the same issue when running .33 Radio and Old bootloader.

Leads me to believe its CM10.1 and or 4.2.2
[Nexus 4 Original Android Development] CBX133:
Did you install the new 4.2.2 Radios? I have heard about more finicky 3G switching on the new .48 radio vs the old .33 radio version. I have stayed with the .33 and have not had this issue with CM10.1. Just flashed Franco r86 tonight so have yet to run into that issue yet.
[Nexus 4 Original Android Development] digitallysick:
So if i get the franco kernel app and the franco kernel what values are optimal to fix the nexus 4 colors? Currently on stock black looks grey and it seems to bright how do i fix that?

Bull****. The phone still throttles when hot. I would post screenshots but I just rebooted and I'm too lazy to test it out again. Go play GTA3 for an hour and look at your cpuspy stats. It still kicks down to 1ghz ish. Although I will say that r14 seems to be a LOT smoother, especially during after playing GTA3 for a while, and the phone seems to be somewhat hotter than the r9 that I was previously using. Although this could be a placebo, I really doubt it. The difference in the heat of the rear glass is very noticeable.

Again I have no evidence to back me up because I didn't bother taking screenshots, but the CPU seems to flip between max speed and throttled clocks a lot more with r14 whereas on r9 it would kick down to 1.1ghz or 1ghz and stay there.

Something has been bugging me greatly. Few months ago I was snooping around github.com/android kernel sources and I saw they merged a completely renewed android power management tree (wakelocks, suspend, etc etc) and I was hoping they would use it for the Nexus 4. They didn't, but they used it for manta (Nexus 10). Apart from different code (old wakelock etc drivers has been around for 4 years) it has some cool features like a maximum amount of allowed wakelocks and a wakelock garbage collector. I'm trying to port it to our kernel (shouldn't be too hard since both kernels are 3.4) and if I'm successful see if its any good against what we have at the moment. I still have to read most of the code paths to understand the changes, but from what I could read from the commit description etc it looks good. I'll will keep you guys posted ofc.
