I didn't see any battery improvement from -25 to -175 and every combo In between on builds when UV first became available ( 62-63 I think ) tested for days no diffrence at all here .. Didn't bother with 67-69 , .. Every phone different though . but - 25 not going to do anything , but good starting point to see what your phone can handle

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

100 across the board should be fine for everyone (stated a few pages back)

I am at 150 less across the board and running fine. Just take it one clock speed at a time.

How I tested:

Set max clock to the clock speed your undervolting, decrease 50mV, set to performance governor, do normal tasks of the phone for 30 mins or so. Rinse and repeat for each clock.

If you get no freezes/slowdowns in that time you should be fine.

Thats what i am saying, your sarcasm is inappropriate because most users here get 6 hours screen on time on wifi doing usual stuff messaging browsing music phone calls so get your facts straight. But if u play need for speed of course wont last 6 hours.

My device can handle up to -150 but to be safe i decrease constantly by 25 until i see it is not stable so i increase the frequency some volts more. Dual core & -100 gives me great battery life.

Care to provide links to those pages where 6+ hours were obtained using the phone for regular things by MOST users?

You're always feisty dude....chill out...get laid...enjoy life.

I monitor this thread just like the rest of the people...i talk to someone using the test kernels. Him and I both receive 4-5 hours of screen on time.

Most that provided a screencap of 6 hours weren't using their phones for browsing, calls, etc....some showed being on airplane mode.

But maybe you live under a cell tower and have great reception..making you an exception.

[Nexus 4 Original Android Development] Silencer96:
My nexus hasn't arrived yet, but judging by all the complaints about the screen's graininess due to the bad pre-set colours, I reckon it'd be best to change my kernel on day one. So let me get this straight, if I install this kernel, my battery life will improve noticeably and so will the screen, right? The only trade-off is that two of the four cores will be inoperable most (if not all) the time, but that will hardly make a difference, as in the end user won't notice anything other than slight lag every now and then?
[Nexus 4 Original Android Development] kioshi:
If you install this kernel on day 1 of powering on the device, you'll enjoy the colors. Right now its half and half. Some like the new colors, some dont.

Battery life will improve based on what users have been reporting coming from stock kernel on here.

With 2 cores on or single core on, it shouldnt lag, at least it hasn't for me. This kernel will provide butter smoothness when operating your phone. You can always input the command in Terminal Emulator and have all 4 cores on.

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

[Nexus 4 Original Android Development] deltatux:
It onlines cores when needed since r69 (latest revision) supports core hotplugging unlike r61 and r62. r61 was all 4 cores on, and r62 is 2 cores on only.

There's still a great debate as to which is better but with r69 hotplugging, the battery life is much better than r53.

With r69, does it basically tweak CPU like pistons in an engine: turning two of the cores off from day to day use, and only using the remaining idle cores when more intensive processing is needed? And from what revision on has the PA colors?

Sort of but instead of the cores being idle they go offline. Also it goes down to one core not two.

Meesa back! Lets see what I come up with today after wrapping up whats been happening in the thread!
[Nexus 4 Original Android Development] drawde40599:
69

Been testing 69 since u dropped it some feedback from MY phone

Hot plugging ----very good , its smooth and fast , but found it stumbles during normal use , almost like it got confused if that makes any sense at all

Dual ----- also ran very good faster than hot plugging no stumble at no issues at all

Quad _--- best out the three , very fast so smooth no issues its what I'm running permanently ATM

All 3 gave me 4+ hours screen on ,I can't say what one was better for battery I shoot for 4 hours and anything more is a gift , had no heat with any of the builds at all , all testing done with 100% stock settings besides fync off loggers off .

Im going to try quad with your cfq settings from build 37 i belive it was faster build with same 4+ hours on battery

Thanks franco its but much for detail but .....;)

---------- Post added at 06:20 PM ---------- Previous post was at 06:08 PM ----------

U no what I forgot to add , I ran the stock kernel this week for a day and noticed a pretty good difference in data connection , stock kernel didnt have the issues I'm having loading pictures from falcon pro twitter app , and loaded internet faster on data connection , no issues with WiFi on either tho . don't no y but it was noticeable

Thank You. That dude always has **** responses to people...ignoring him.

Franco - Def seeing better screen on time on r69. Whatever you do on the next nightly build, keep it like r69!

I usually get around 1 hour of screen on time per 25%. On r69 I was at 1 hour and 15 mins of screen on at just 79% battery! Impressed.:good:

[Nexus 4 Original Android Development] jtwlbz:
Yeh I like 62 better than 69 as well
[Nexus 4 Original Android Development] franciscofranco:
Thanks.

I'm changing the hotplug driver code to never hotplug cpu1 so it keeps cpu0 and cpu1 online all time (screen on only ofc) and hotplug cpu2 and cpu3 depending on load. This mode will be different from dual core and quad core modes because those modes run without any hotplug mechanics what-so-ever.

I'm also playing a little bit with the color defaults, I think I found a good balance between PA's deep color saturation and natural color level. Having a little fun now and will release as normal nightly as soon as I'm happy with it.

What RGB gamma do you guys get with Display Tester app? A gamma of 2.2 is what any calibrated screen should be and I don't get it for any color with r68.

Gamma is the only issue for me. These settings are no good on my device, nor are PA's. Is there any reason we don't have faux's gamma control? Matrix and others have it. I used to have 2.2 with them.

Damn, for a second I thought you just pushed out r70 lol.

As for the hotplugging in r69, I find that if I make it easier to online and harder to offline seems to have the best effect in terms of smoothness. Here are my values:

Online single core: 265

Offline single core: 120

Battery and performance seems to be similar to r61/r62 based on my usage scenarios ... can other people test this?

I can vouch for this. Bought his app when it first came out and his kernels has been nothing but exceptional.

Updates come regularly and only gets better, if there's a problem with the kernel causing critical reboots or whatever it may be, franco responds to it and pushes out an update asap (as he already demonstrated with r12 and r13 :) ) sometimes if people are in the testing fever, he'll release a new update to a kernel without any changelog to have unbiased feedback which is always nice because without honest feedback, it can't get any better :)

[Nexus 4 Original Android Development] franciscofranco:
This is basically the summary from r53 up to r70. Its a very small version of all the testing I made, but its enough. I hope its a great release :)

r70:

* Big Hotplug driver changes that made me push its version to 1.0

* Made Deadline IO scheduler default tuned with values tested by users (thanks guys)

* Improvements in the thermal throttle driver to better react on thermal changes without derping

* Improved screen colors, more saturated, deeper blacks, better white

* Sync with JOP40G kernel changes

* Lots of small misc changes visible on github

The hotplug driver during screen on will never offline more than 2 cores, and it will load the other 2 if the load is high. This is a mix between a the standalone dual core and quad core mode while using the hotplug routines. Using the paths I posted some pages ago its still possible to toggle between using the routines or either dual core or quad core mode.

Have fun, and I hope the colors are good for everyone :)

Re: [KERNEL][GPL][N4] franco.Kernel - r70

Yo Franco, was loving r69s color but just flashed r70 due to all the new hot plug changes. So far, r70s colors are a little too blue for my tastes. Can the color values from r69 be applied in the current version, or are the values "hard coded"? If so, what were the values from r69?
[Nexus 4 Original Android Development] franciscofranco:
Colors are hardcoded. It looks blue because your eyes are just used to the previous yellowish tones. Let them get used to it and it will be fine. Its whiter than blue.

You can always tune the blue RGB value a little bit - easy if you have any of my apps that maintain the colors on screen on/off.
