I'm confused, do you mean just within your kernel or in general?

(Anecdote) Screen off idle time was one of the first things that for me hooked on your kernel. At home, on WiFi, I was dropping 20%+ while sleeping on stock whereas with your kernel it's 5% or so. (/Anecdote)

In general.

That was because when the Nexus 5 was launched they had a bug on the Wi-Fi drivers that frakked the battery life. Before they launched 4.4.2 I merged a couple patches from kernel_common (base Kernel tree from Android) that fixed it ;)

You have a wakelock problem for sure.

Just noticed with the test kernel I am getting SoD. Phone rebooted and went to Dalvik instead of ART. Was running fine on r55.

Same thing happened to me, was on ART, phone crashed and rebooted on Dalvik.
I see that you're also using PA, that might be the issue.

For me, changing to Dalvik and doing a more conservative UV (-50 instead of -75) than what I had in R55 got me through the day without a crash. Will try again on ART with the same stable UV to see if I can isolate the source of my reboots.

Ah right. I'm undervolted a fair bit. However r55 and ART with my UV runs well. May go back to stock voltages.

Go back to stock and then UV bit by bit until you find how low you can go while being stable. For me it's between -60 and -50. My previous -75 UV that worked fine with R53,54 & 55 is not stable in R56 with my configuration. Also, just changed to ART, will run a couple cycles to see if it any problems arise

Rooted apps as is aren't safe on L. I was sent into a bootloop for loading up Greenify and granting it root.

And for good reason, too. There's many bugs that can only be squashed by Google right now, people stating that L is stable clearly haven't played around with it enough.

Seeing a stupid comment on Google Play about an app you love and marking it as "spam". You've done it too.

I've been on it since day 1 and no issues for me so don't count everyone in that statistic.

My voltages have been fine on all previous versions with ART except r56 test. So I guess it is voltages.

Only issue I found was Facebook comments being transparent and my carrier widget being transparent. It was solid otherwise.

Sorry for going OT.

Here we go, I think I have finally finished the init.d script for my settings.

This makes your life easier as you don't need to apply these settings in the app manually now.

VomerTweaks allows you to get insane battery life with minimal/no performance impact. Who doesn't like that!?

NOTE: franco's app does A LOT MORE and I highly recommend you buy it and support his work :good:

Note: Users on STOCK ROMs will need these BUSYBOX & INIT.D apps to enable automatic application on boot.

Current Features:

  • CPU Under clock
  • GPU Under clock
  • Hotplug Optimizations
  • Color Profile Application
  • Governor Optimizations
  • Vibration amp set to 75 (default is 100)



What do I need?


  • Start by downloading the latest version of the script from this link. Make sure the downloaded file is named 01VomerTweaks (no file extensions)
  • File Manager that allows root mounting
  • Optional: Users of Tasker can get Tzfardaya's file (HERE) and import it into tasker

If you flash a new ROM/update - you will need to re-do the steps below as the script will get erased in the process

Let's Roll!

Method 1: Flash via Recovery (easiest)

Note: Please ensure you are running TWRP v2.7.0.0 or higher when trying this method.

Thanks to @no.one.writeme for help with the script

Simply flash this file using TWRP (I do not use CWM so I recommend you use TWRP with this file)

Method 1a: Manual init.d Application

Open your file manager, go to your root directory, and remount your /system partition as RW instead of RO.

Once the /system is mounted as RW we can move our script to the init.d folder and change the scripts permissions.

The init.d folder is located here:

/system/etc/init.d

Move the downloaded script to this folder

The name of your script determines the order in which it is executed. The first two characters determine the order of execution. The ordering is as follows - numbers from 0-99, then letters from A-Z. I have already named the script for you and does not need a re-name unless you really want to change the sequence. I have it set to execute first because I want to get kernel tweaks done as early as possible.

Now, long-press it and select "Change Permissions" (or however this is done in your file manager).
Give User, Group, and Other read, write, and execute permissions (755). See Screenshot

Your init.d script will now optimize your device to my tweaks quickly and efficiently at every boot ;)

Method 2: Manual Execution

If you like doing this manually:

  • Open Terminal Emulator
  • Type: su -
  • Type: sh /sdcard/Download/01VomerTweaks
You will see a pause/delay of 20 seconds and then all things should be set for you

Try it out! It is work in progress so I will keep everyone posted on changes/updates.

Please do report any issues you might face (it's unlikely) :)

Special thanks to @franciscofranco @The Gingerbread Man @bigknowz @Tzfardaya and everyone else who contributed for their help :good:

is this working fine with latest r55 build

That was because when the Nexus 5 was launched they had a bug on the Wi-Fi drivers that frakked the battery life.

It's still frakked on stock though. If I use stock, there is no way that it'd look flat like it does on your kernel.

In case you missed my previous post, I wanted to ask you something. On Play you wrote:
You have to make your profile again as I had to change the backend code for portability.

Does this mean that if I load for example the Piereligio premade gamma profile, I get different results than before?
Because I loaded it, and frankly I can't really say that it looks good to me, so I'm wondering if that is why.
Thanks!

Hi guys, i updated from r47 to r55 yesterday and got 2 SOD's since then :crying:
Can someone confirm/contradict this issue?

Device was N5 and ROM was Omni from yesterday, too.

Since r47 and some Omni-Nightly from 1-2 months ago there wasn't a single SOD/any other issue.

Thanks4advice!

I haven't had a SOD since r52 or so. Just throwing that out there. :)

That's only for the Nexus 4, it doesn't apply here.

I have a question. i put input boost freq to 300,000 but everytime i touch the screen the franco kernel boosts to 1036000 mhz why is tat?

It's 300000.

    Hi all.

    Compatibility:
    It should work on any rom by following this logic:
    Builds (starting with r65) are Android 5.0 Lollipop only.
    Builds (starting with r72) are Android 5.1 Lollipop only.
    Builds (starting with r76) are Android 6.0 Marshmallow only.
    Builds (starting with r97) are also compatible with Android 7.0 Nougat and Android 7.1 Nougat .
    Builds (starting with r114) are also compatible with Android 8.1.0 Oreo.

    This does not work with "CAF" roms.

    Download:
    https://francokernel.app

    Installation:
    Flash the zip in your recovery
    or
    Auto-flash from Franco Kernel Updater app

    Features:
    1 - Legendary battery life
    2 - Flash & forget
    3 - Typical interfaces like display adjustments, sound control, vibration control, and all that boring stuff
    4 - Idle power consumption reduced to the absolute minimum (if you have wakelocks from 3rd party apps you're obviously on your own)
    5 - Support for FKUpdater's Performance Profiles
    6 - Magical support, I'm here every day, checking posts almost hourly, ready to help anytime (well, unless you fail to read the OP, which contains most info you need)
    7 - Seemless integration with my app FKUpdater
    8 - No crap placebo patches, or "magical" optimizations
    9 - Probably more, check my github for all the details - the code speaks for itself

    Disclaimer to moderators:
    Slight OT is fine, but when users decide to act stupid they should be dealt with with the appropriate means - its really annoying for me when OT turns crazy. Please put the warning/ban hammer anytime any of you think there's lack of respect and/or too much unwanted OT crap - but if it doesn't meet this criteria let the OT posts alone. Thank you.

    Cheers!

    r33 is pushed! Thanks for all the tests during this last 5-6 weeks. Before you ask yes this build is newer than the last r33-test. Most of you that followed the changes know basically what changed, so this is a generic changelog:

    * FK does not work with CM or derivates anymore so don't flash if you're in one of those roms. Also make sure you're not undervolting too much, this new build might be a little extra nervous regarding low voltages
    * This is a huge release with more than 1 month of consecutive testing. It contains probably more than 250 new commits which include a lot of patches from Codeaurora with fixes, performance improvements and battery improvements. Subsystems like cpufreq, audio, video, display, thermal, power management etc have been improved. For a complete list of changes please visit my github repository
    * My hotplug driver has been improved as in having a complete new set of tunables for advanced users. Visit my repository for the documentation of each tunable

    Enjoy!

    I'd like to wish you all a Merry Christmas, lots of food, kisses, hugs, and quality time.

    From my part thanks a lot for the great 2 months since the N5 was released, that, for me, is a great gift, thank you all.
