I take it we can't set our voltages anymore? I've cleared app data, uninstalled and reinstalled. Kinda weird. Shows up on my phone and not my wife's. The option to change voltages in the app on my wife's phone is gone. It is the paid for app.
[Nexus 4 Original Android Development] andyli1985:
Your wife's phone might not be running francos kernel. The option is not there if the kernel doesn't support undervolt.

She's been running Franco since she got the phone. Just flashed 121 on it tonight.

Thank you Franco!

What's next?:) Also, is the volume already improved with your current KERNEL?

Thank you.
[Nexus 4 Original Android Development] ÜBER™:

Next on the kernel I don't know, not really fussed about it, current r121 works great, I can focus on the app. Check my G+ if you want to see what I've been up to.

[Nexus 4 Original Android Development] whittikins:
I haven't had a chance to try your kernel yet, but I wanted to point out what I think is a big issue on stock kernel. I've had the phone a couple days and noticed very fast battery drain while the screen is on. Definitely faster than my galaxy nexus experienced. I then noticed the phone is using 1.5 GHz step pretty aggressively even when I'm just using gmail, reddit, and tapatalk. I've attached a screenshot of it when I've only been doing light tasks like this.

I also noticed that input boost seems to be enabled and locking to the highest clock speed the whole time for 1 core and another core stays between 1 GHz and 1.5 GHz until you release the touch input. I think this is destroying battery, especially for those of us using swipe typing.
[Nexus 4 Original Android Development] ChongoDroid:
Thank you, so in theory a higher min CPU speed won't really effect battery life as the device still gets into deep sleep. (Actually goes to sleep faster if I remember.) I'm gonna play with 486mhz min for a while and see what its like for battery life.
[Nexus 4 Original Android Development] kabauterman:
the Stock Kernel clocks the CPU while screen on from 1026 to 1512 all the lower steps are not used.

with ondemand now from build 5 the CPU clocks lower some times but most of the Time it is still over 1 GHz.

I don't understand why the CPU burns so much energy because I think not all 4 Cores are active but the Phone sometimes realy burns..
[Nexus 4 Original Android Development] whittikins:
That's not what I'm seeing at all in system tuner. I see the CPU idle down to 384 megahertz.

[Nexus 4 Original Android Development] Testraindrop:
Wow thats some useless energy waste :eek:

I can only say that my Galaxy S2 is mostly at lowest level (200Mhz) and on touch input is stays on 500Mhz of 1200Mz max. and on only one core.

Those Krait cores should be way faster than what the S2 has, so 2 cores only for touch input and max frequency on one of those is only wasting battery...

Smell some extreme battery improvement there :D
[Nexus 4 Original Android Development] exadeci:
Nice !! Could you create a small changelog on the first post so we know what you change/add (so we don't have to look at all your posts and you won't need to repeat it :)

PS: Btw in fsync_enabled there was a N does it works with Y/N too ?
[Nexus 4 Original Android Development] kabauterman:
I my case 384 is just used while loading.

If screen on 1026 to 1512

if screen of without loading just deepsleep

all between 384 and 1026 is not used at default with stock kernel here (no CPU changing apps)

I read out with CPU Spy Plus (no root just read states out),

because system tuner changes CPU settings why would you say It's no System tuner setting it it works for you??

if I use System Tuner the Clock jumps pretty heavy every sec no matter if I touch the screen or something else.
[Nexus 4 Original Android Development] Noobla_Khan:
Getting on 2 days here with the various iterations of franco and I think it's safe to say battery life is vastly improved over stock. Came from an SGS2 to N4 and battery life was the only thing I missed about my SGS2 but looks like that's no longer an issue.

Thanks Franco!
[Nexus 4 Original Android Development] lamlux:
Just flashed v5 over and ran Quadrant for whatever reason, scored 5266!

Antutu is 9821

Sunspider is 1900 Chrome

i'll continue testing and test battery life as well.

Last kernel I ran (I think it was 2) I had 20 hours on battery with 32% left... !! :good::good:
[Nexus 4 Original Android Development] Serious_Beans:
I hope Franco can confirm/deny this but I don't think the clockspeed of the phone matters too much for battery life, I've tried many different variations of clockspeeds on my GNex and other Android devices before it and I've never really had vast batterylife improvements lowering clock speeds. Even undervolting isn't too useful.

http://xdaforums.com/showthread.php?t=1478406&highlight=undervolting.

There are more things to improve battery life rather than underclocking and undervolting. I really don't notice a difference doing either of those. Not 100% sure about this but from experience and reading random things here and there about it, don't see a reason to bother with adjusting clock speeds.

Just my 0.2c :)

Have had something strange now:

Was writing a text in Whatsapp as the screen suddenly goes black and no reaction to the power on Button. After aprox. 5 sec the power on Button worked and I was back on Lockscreen. After Unlocking I was back to Whatsapp with the message I started writing and all, so no reboot I think.

What was that ?

Have had thad Issue also yesterday but wasn't sure about that. Have had a look into logcat and kmsg but couldn't see anything in it....
[Nexus 4 Original Android Development] b4ifuru18:
What build are you running? I had this happen on build 4 and others had it happen on build 3 and 2.
[Nexus 4 Original Android Development] IAmAN00bie:
Aside from the screen your CPU should be the biggest battery drain. Changing the CPU frequencies makes a big difference in power consumption at least compared to changing the voltages only slightly. You just won't notice the battery savings that heavily because the screen drain is far more in comparison.
[Nexus 4 Original Android Development] Stretlow:
Just updated Franco's app,

When I look at the freqencies it says max 1512, min 1026.... i that right?

I just went into my G+ app and its scrolling was as smooth as butter on r18. I am using it with PA beta8.
[Nexus 4 Original Android Development] estallings15:
Same, but on MinCo v6.
[Nexus 4 Original Android Development] akhan47:
I'm also using PA B8 and I don't seen evidence of any lagging or jitters on R18. Smooth sailing as always with Franco.
[Nexus 4 Original Android Development] CMNein:
I'm not either (latest CM10 nightly). For those that are though, it's hard to use G+ or Tapatalk as gauges of lagginess however (for the most part) as they do lag in scrolling from time to time since they're data dependent as well.
[Nexus 4 Original Android Development] scream4cheese:
I'm guessing tonight's kernel will be updated to reduce the reported lag. I hope there will be more improvements for tonight's update.
[Nexus 4 Original Android Development] estallings15:
I let a bunch of images load and then scroll as fast as I can in both directions. You make a good point, though. One would think people would know that, but one would probably be giving them too much credit.
[Nexus 4 Original Android Development] drawde40599:
I'm not going to waste my time commenting on those Childrens comments out of respect for Franco , all I'm saying is if u go back to page 1 of this thread to current , cm10.1 mentioned having " kernel" issues more than any other ROM , no ROM is perfect but there are more issues with CM .
[Nexus 4 Original Android Development] jarjar124:
i didnt mean to disrespect anyone especially Franco! If you saw my post, i quoted someone that said cm was the problem with the jerky lag. i proved him wrong by saying its not just a cm issue. please look at what i said before saying that i wasted your time...

Anyone having issues where the phone locks up and then does a reboot after being in a deep sleep state?

The last few days I'll go to bed, and then in the morning when I wake up the screen is locked up and then does a reboot. It doesn't happen during the day ever. Is there a good way for me to troubleshoot this? Can I turn on some logging before I go to bed and check what the phone is doing?
[Nexus 4 Original Android Development] cchant:
I haven't had any problems on any version of Franco's kernel besides screen on time. The phone goes in to deep sleep no problem. If I leave it alone I can get well over 2 days without charging. But regardless I always get about 2 hours of screen on time. I've tries auto brightness and leaving it at 50% and taking it all the way to as dim as possible. Doesn't make a difference

[Nexus 4 Original Android Development] GFXi0N:
If I leave my phone without Google now, Google sync, data off, wife off and directly switch it off, I get 3 weeks battery life!

The true benchmark is seeing how the battery behaves under normal usage, not disconnecting everything and letting it be for hours and hours..... Try browsing, doing some social networking, etc... Then check how the battery behaves, if not, you are just testing how the kernel handles deep sleep states..... IMHO

For me, between stock and Franco kernel the only difference has been the idle time. I still never get above 3hrs SOT. Greenify, Wake lock detector, GSAM Battery, CPU Spy, all this stuff I run to little to improvement. I'm just gonna uninstall all that stuff and use the phone. Franco is great anyway but so was Stock. At least I can increase the volume and change the screen color though.

[Nexus 4 Original Android Development] getaceres:
I don't know how you get better battery life than an iPhone. Crappy battery life is the price we pay for having multitasking. I had an iPhone 4S with iOS 6 and I hated that the applications were continuosly killed (you open one, you see it loading, it loads and then loads the data) but not having anything running in the background guaranteed a good battery life (not so much better than Android but definitely better) and it applies to onscreen time too which was way much better.

I prefer to get a notification from gmail or whatsapp, opening it and seeing the message or the email immediatly but the price I pay for it is to have less battery, and I understand that it must be like this. Having said this, I think that Android can improve a LOT when working (on screen time) because this kernels do the work when it's idle extremely well.

The first drop down box where it says "Other", you need to also look at the "Kernel wakelocks" and "Partial wakelocks" to see what is actually keeping the phone awake. Just looking at the "Other" page alone isn't enough.
