Sorry i haven't gotten to the dual core test, however i believe that 4-core up and running is the ultimate goal.

I believe that there's much more to be discovered in this kernel build, some key things that i wanna know is

1) Dual channel memory optimization (can processor 0 and 2 be turned on, with 1 and 3 offline Franco?)

2) Can the kernel or the Franco utility monitor "power state"? (i.e.: on external vs on internal power)

I've taken a look at the latest compiled kernel that was published with Paranoid Android beta 7 (3FEB) and the minimum processor speed is

no longer locked @ 1026Mhz as was previously stated. It sits @ 594Mhz now. hispeed_freq still goes to 1026Mhz.

So for my current running setup, I'm on r61, with Minimum CPU set to 594Mhz and Max set to 1188Mhz.

IMO the phone runs very well. As i stated in my earlier post, the difference between 1.5Ghz and 1.2Ghz (1188Mhz) FPS wise seems minimal.

The phone seems to be faster to respond since it doesn't have to come out of deep sleep and run @ 384Mhz,... and I'm UV'd so the power cost for 594Mhz is nearly identical to the stock voltage of 384Mhz. YMMV but this is my input on the matter so far.

Re: [KERNEL][GPL][N4] franco.Kernel - r53

Never in the past 10+ years of owning a smart phone or 2 way pager have I been able to go 2 full days without recharging!

Right now I'm at 31% left after 30 hours with 3.5 hours screen time using r62! Extremely pleased and more so that I get to rub it in to the sg3 owners at work that bashed my nexus4 because it didn't have a swappable battery!
[Nexus 4 Original Android Development] yoyoz808:
Hey franco, i tried r61 &r 62 and like them both but i decided to go back to r53 to try messing with the online cores thresholds. I found a good balance with smoothness and battery life. I don't really think UV has any substantial impact but was wondering since a lot of people like having 2cores on all the time, maybe you could give the options like r53 to keep 2 cores on all the time or control single and all cores and when to turn them off.

Thanks for the reply.

Any other tricks you can share to survive that screen on time?

Because with Wi-Fi only I struggle to get even 3h30m....I never touched 4h, let alone 5h or 6h, regardless of franco.kernel version (or any other kernel for that matter; for ROM I tried PA, CM, AOKP, and stock. Battery is about the same on all these ROMs).

Re: [KERNEL][GPL][N4] franco.Kernel - r53

I think Franco got it right with r62... It works flawless!

I do understand some people wanting the other two cores online on demand... That should be cool as well, especially when gaming.. That way the load is shared by all 4 cores instead of maxing two cores to the top... I believe that can save some battery as well. But coding a widget would be to out of the way in this development project.

If that's the case I suppose Franco would need to implement hotplugging for the last two cores... But also hotplugging taxes the battery... So it might be under an extreme demand circumstance. Which doesn't sound like a bad idea... Especially if you're gaming for a long period of time.

I don't really see a need of the extra 2 cores for 99% of things... That 1% would be gaming and we can benefit from the 4 online cores saving a bit of battery sharing the work load between all 4 cores... But just for extreme situations... Otherwise we end up in the same place using 4 cores for little things like loading an app, scrolling, etc.

Just my 2 cents ;)

Franco, I gotta say, I like your philosophy. I even call you putt in a few of my OPs (even on RootzWiki) I all for the "allow app to turn on more cores for people who want it" concept but the way you build the Kernels, I never tweak anything and am pretty darn happy with the results. Please keep up the ideal that the kernel is perfectly balanced right out of the box, but tunable for those who want it because it really makes your kernels outshine the competition. Cheers!

Yup, it changes some screen on while plugging or unplugging option and allows the phone to deep sleep via power button and uh saves 60 ma while charging (thus making charging faster/more effective) by doing something...

Re: [KERNEL][GPL][N4] franco.Kernel - r53

Pretty simple.... Leave your phone idle for about 18 hours... Then use it with screen on for another 6 hours until you drain the battery... Also keep it connected to wifi. ;)

Regular use with decent battery should allow you 8 to 10 hours with 3 hours of screen on time. There's no silver bullet after that. And that's actually great comparing to Stock kernel!

People that are saying they're impressed and posting battery life will be amazed when Franco adds undervolting. Some kernels have it, and let's just say 3.5 hours screen time with 20 hours idle turns into 4.5 or 5 hours screen time with 20 hours idle.

He's working on other aspects first, which I can appreciate because it will be more stable. I would trust this as a daily driver for anyone, whereas I wouldn't some others. Definitely looking forward to future improvements here!

Re: [KERNEL][GPL][N4] franco.Kernel - r53

Franco, may I ask what is wrong with the way stock kernel handles the cores? I flashed stock today and it seems to manage things pretty well. For example, I set the min to 384 and when I'm just staring at the screen only cpu0 is on and stays mostly at the lowest frequency. Upon touching the screen and scrolling through the xda app 2 cpus come on (cpu0 and cpu1). When I start doing more intense tasks the other cpus will come on, sometimes it will be 3 cores, sometimes all 4. For me this seems to be a good balance and usage of the cpus and I'm still getting 5+ hrs of screen on time.

I set governor to interactive and tweaked the settings to try and keep it from ramping up. Maybe someone else could give it a try and see if it works well on their device as well.
[Nexus 4 Original Android Development] drawde40599:
Im not franco but i have used stock kernel for weeks , Stock kernel dose work well , its actually a great kernel , but battery sucks , it throttles after very light use , it heats up , it stays at the 1024 freq almost whole time u use it witch is max after throttle , I could go on and on but I won't , Franco has fixed all these issues with his kernel IMO and when he gets to milestone build pretty sure no one will ever mention stock kernel agn ;) I have no idea how u get 5 hours on stock , I couldn't get 2 I now get 4.5 , so u should get 10

[Nexus 4 Original Android Development] lightosx:
Re: [KERNEL][GPL][N4] franco.Kernel - r53

What am saying is with the custom interactive tunables I set on stock kernel I'm getting similar battery than r62 which will keep 2 cores on all the time where as on stock it may use 4 cores, but at times it also only uses 1.

I agree with drawde40599 that the throttling is better with franco kernel and I love the other changes he's implemented, I just noticed that the hotplugging on stock doesn't cause those microstutters, so maybe there's something we can take from it or make it a little bit less aggressive, so it won't go up to the higher frequencies as often.

This weekend on r61 performance optimized (interactive tunables, cfq, UV-125), I got 5 hours screen on time with normal usage on WiFi, brightness set to auto/low, and this included about 1 hour live TV streamed to my Nexus 4. Same usage on stock kernel would last only about 3 hours SOT.

With r62 you probably get some more battery life (someone here posted 6 hours SOT on WiFi), but currently at the cost of capping performance to 2 cores, which definately shows in benchmarks and heavy gaming, actually in any multithreaded or multitasking heavy usage szenario or apps.

I fully agree with consensus here to request next Franco kernel to be r62 with the option to either manually add the other 2 cores (e.g. thru a switch in his kernel app, don't need a widget), or automatically add them thru throttling in heavy load szenario.
