I couldn't believe those people talking about a flickering screen but I just encountered it too...

First my device didn't wake up after pressing the power button. After several tries it worked but the screen did this sort of flickering or however you call that :D

I rebooted 2 times but it still showed the symptoms AND my homescreens were empty (maybe the risk of fsync disabled?!), had to redo my homescreen setup.

Well, I got it fixed by flashing a different kernel and as I have no LOG to share I'm blaming myself but just wanted to point out that this problem really exists.

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

Franco, I had to post because I wanted to share my results with everyone! Thanks to this awesome kernel, I managed 18 hours, 5 hours screen on time, 10 hours on 3g, 8 hours on WiFi. WITH 20% left over :D This is with default settings, except for the fsync and logging which are turned off. AND I have Facebook, twitter, email, gmail, drop box, and tumblr syncing in the background! Thank you so much!

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

I just had a reboot whilst updating an app on play store. Weird thing is the status screen says uptime of 14hrs but the battery stats clearly shows there was a random reboot...

I have a problem with r53 regarding synchronisation.

My sync is not working with r53.

I only get new emails, when i manually refresh and i to get whatsapp messages, i must open the app.

back to r50 and everything works fine.

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

How many wakelocks do you have? Wifi or 3g. Because that doesn't sound like good battery life to me at all. I'd have about 70% left after that time.
[Nexus 4 Original Android Development] shr33kant:
I had this also, all default settings. I couldn't reproduce it either. It happened right after I flashed the kernel actually...just re-flashed stock then r53 and it went away.

Hey Franco,

Can you please tell me if there is a conflict between your kernel and this mod?

http://xdaforums.com/showthread.php?t=2028289

I'm asking this because when I use this mod with your kernel the touch screen barely senses touches (I have to press on the screen pretty hard...), when I use this mod alone without your kernel it works completely fine and when I use just your kernel it works fine (but I find the touch responsiveness is not sensitive enough for me...)

I would love it if you could take a look at this for me.

Thanks!

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

I did post a few/lot pages back that r53 was ok @morning, but then I came back home, 3g was down in my town, and r53 gave me no signal or emergency mode (a reboot fixed it for a few minutes, then dead again).

Maybe something in it has issues with low signal or no 3g? (only GPRS or edge was available, chequed with other phones)

Anyone know where I can download the stock kernel to test this gmail issue?
[Nexus 4 Original Android Development] DerKiLLa:
I have double checked it.

First i upgraded to r53 and have this issues

Then i downgraded to r50 and didnt have problems

then i installed again r53 and had the sync issues again

finally i decided to stay on r50

Just flash your Custom-ROM to get the Stock kernel. Or are u using StockROM?

Min frequency showed as 1188 on my device after update although wasn't sure if that was just an initial display issue, so I'd ensure that you wipe app data to correctly pick up any new defaults.

You may also wish to set the I/O scheduler to deadline after stats shown in previous pages, default is still row. Personal Choice.

Incredible amount of customization now possible. If I felt like I understood all the options more the @FF I'd tinker - so very happy with default! :)

Need help in maximizing my Nexus 4 and my Franco Kernel

Hi guys, I'm not active in XDA, but I'm a Nexus 4 owner, a proud Franco Kernel user, now rocking r53 it's a very smooth kernel indeed, and I've been keeping watch of this thread almost daily since r20. Thanks for your kernel Franco, awesome job dude! I believe in the rationale of all the modifications of this kernel, why certain things are adjusted in certain way, thanks everyone for educating me of these things!

I would like to ask one more favor from you guys, I need enlightenment. I'm still clueless on how come my battery never lasts up for 2 days, meaning it never reaches its 40th hour no matter how light I use it. Yes, I'm also a power user but only occasionally, on the regular working days, I'm a very light user. I use Franco's default kernel settings, because I believe its the optimum setting. But I still keep getting 50% battery after a whole day at work, just leaving my phone on the desk at work, just sending some SMS and made very few short calls, that's just for 14 hours and only 1 hr 30 mins screen time. No games, no videos, streaming. See screenshots below:

I really envy those other users who can just use their phone without too much worry, and I believe r53 is responsible for make their phones reach such limits, quite unreachable in stock, and just being carefree on phone use yet reach 5-6 hrs screen time, with some surfing, some games, and wifi on for long duration, and running on battery for more than 30hrs. My sister has an S3, and she is able to make it last for more than 2 days, she is not a poweruser, but she is also not a techie person to religiously conserve battery, sometimes she even forget to turn off her mobile data, and that doesn't seem to have a kick on her battery. Don't get me wrong, I'm not into S3 vs N4 thing, but I'm just here to look for answers, how come vanilla android and its stock kernel is quite of a disappointment for me battery-wise, not matter how meticulous I'am in switching off stuff, I thought Nexus 4 will be more promising in the battery department coming from a Nexus One.

I'm not blaming it to franco's kernel, its been like this for me since stock, and I don't expect a magical leap of difference in using a modified kernel, the difference is too minimal for me to notice yet, or maybe I'm just too ignorant to feel the improvement, I don't know. This is in practice, but in theory, I so much agree with all the hotplug driver improvements, and why constricting the 2nd core in light swiping is good for the battery, etc.. I know my apps are to blame, I get the whole rationale of the apps causing wakelocks thing and not the kernal, but I don't even have mobile data, and all my social accounts are signed out before I switch my wifi off. I don't see the point that I have to uninstall them since I've already disabled location services and NFC.

I think, there is something I'm really missing here. It seems that everyone is dancing the same song, yet I'm the only one who is off the tune. Can anyone please help me?
[Nexus 4 Original Android Development] tweaked:
I don't no what you are complaining about. I'm getting the exact same. Always have. With kernels and roms I can add - maybe an hour here and there. No one is getting more then 5 hours screen time and 15 hours battery. If they say they are, they lie. I can get maybe 2 days if I never use it. If I play game and stream Music, and text and use it like a tablet, i get minus 10 hours and only like 3 hours of screen time.

Still better then any phone I ever had. I could kill an iphone in 4 hours doing the same. My HTC would last 3 hours total if I played with it in the same way I do this phone.

[Nexus 4 Original Android Development] mikarbach:
I am using Xylon-4.2-ROM together with franco-kernel more or less always the latest version, and stick to the franco defaults. I am not a gamer or power user. My usual average usage over one day is: 1 call, 2-4 SMS, 3-5 whatsapp, google-now, 3-10 gmail, falcon-twitter-widget, fancy-widget, some 5-15min music and occasionally using some apps like, chrome, dropbox and something else. With this usage I have at least 2 days of usage with roughly 4h screen-on time and usually 15-30% battery left. But I also have made sometimes with three days of usage. So I am very satisfied with this combo.

[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
Franco, one thing I never understood about Android was that in vibrate mode the speaker turns on for any notification or sound event. I have touch sounds enabled, and the N4 speaker seems to crackle upon turning on.

Why does it need to turn on even in vibrate mode? Is this something the kernel controls? Pardon me for my stupid analysis but it seems to me turning a speaker on and off when phone is in vibrate is using excessive power? It probably isn't a huge amount of power, but it does take *some* power I imagine to turn on and off the speaker.

[Nexus 4 Original Android Development] rlpaul:
For some reason on my N4, I have to sometimes flash the kernel twice. The first time, I'll get grey bars, can't get rid of them no matter what settings I set. Then I'll reflash the same kernel version, and I'm OK, reboots, change AP settings, doesn't matter, everything's good.

I think there might be some timing issue during the flash process that occasionally causes problems, so I'd reflash the kernel first before passing judgement.

+1.

Put r53 to sleep for >10 mins. Send email to self (from PC). No notification for >5 mins whereas previously HSPA notification is usually less than a couple of minutes. Turn on phone. Signal bars are usually greyed. Whether blue or grey, no notifications.

Same test on r46. Notification are nearly instantaneous.

Edit: Strange... but tried r53 again, and I can't reproduce the problem. Even though I still get the odd BBS stats (e.g. 0% battery drain)

FYI, I chose r46 since it seemed to provide best standby time for me (on an older version of PA). I can accept microlags (if any). Curious to find out how others are testing for smoothness. (For example, Xda often disables its search function -- indicating site overload / maintenance -- so I wouldn't be using this forum or tapatalk as an indiication at all. Unless you have a sniffer online, you can't account for stutters caused by internet or site. )

I test by flinging the apps list in TB or a file manager... but even then, the stutters disappear after all the info is cached (as others have already noted). With perfmon, you can see how the number of cores and CPU freq drop when you fling the same list over and over again.

BTW, I know about about significant changes in r52, but what changes were between r51 and r50? (r51 was initially a blind-test.)

As great as this kernel is for battery life, performance takes a nose dive. The device just becomes far more prone to lagging and stuttering. The most annoying is when opening the app switcher or unlocking the screen, it's painful :p I haven't found a custom kernel that matches stock for lag free butteryness yet :(
[Nexus 4 Original Android Development] Vangelis13:
Re: [KERNEL][GPL][N4] franco.Kernel - r53

With minimum two cores on at all times, yeah, of course it's lag free. There are plenty of users here that find it lag-free as well though.

Are you on cm? Auto-brightness?

Try another scheduler as well perhaps, maybe on demand is better for you.
[Nexus 4 Original Android Development] mikarbach:
I could not confirm this. I am using r53 (with defaults) together with max-CPU-freq-1350. In addition I am using pgm with swipe2wake (which might be an additional overhead). I could not see how smother it should start and in addition the app-drawer (Apex-Launcher) starts immediately and completely smooth. Could it be ROM or Launcher-related?
[Nexus 4 Original Android Development] 3dawg:
Well I'm running CM10.1 and I don't think the launcher has any effect on how laggy the app switcher is. I also don't see how the launcher will affect the lock screen lagging slightly occasionally or just general U.I interactions occasionally stuttering.
