When I thought r98 was the best, I did a clean install for AOKP M4 + franco.Kernel M2 and I have to say battery life is ridiculously good now, without sacrificing "snappiness".

In a poor 3G reception area I managed to pull 2hrs screen on time (browsing) and still had 60% left :eek: (brightness @ ~40%, just plain stock M2 kernel settings)

It's just so good now I'm hesitant to flash another rom/ kernel/ combo to try and get the best Nexus experience (although I want/ need to) :D hehehe

For those having problems with your GPS, this is what I do with every rom I flash. I live in Greece, and most roms are set for US. Open build.prop and find the line that says ro.product.locale.region=US. For me I change the US to EU (Europe) or GR (Greece).

I have never had an issue with GPS and lock within secons. Hopefully this sorts some of the problems out.

is that M2 provides you a less smooth Gaming experience than the r98? I know M2 has a lower GPU frequency than r98.. let's take GTA3 as an example

Thanks

If im not mistaken, somewhere in root explorer settings you have to mount the system as RW.... Mount the system, and then it should let you make the changes.

Hi there,

i try your tip, but i must say that i have no probs with GPS. But the sync is slow, so is this workaround maybe fix the GPS Sync Speed? and what is the Setting for Germany? DE?

Franco's kernel is so good that not only did I not lose battery during standby, but I actually GAINED extra battery ;)

On a more serious note, I assume this 'charging' thing will go away eventually, since the battery is still new. Or maybe I should wipe battery stats since I've been flashing around a bit?

By the way, awesome bit of work franco, until our phone can charge themselves this kernel gives me awesome battery life :D

First time user of Franco.kernel since last night.

When I first used the application, I'm sure the sound control description stated that the value range was between 0-13, at some point it changed to 0-3.

Is this normal? (Running M2 by the way)

im on M2 and today i got a freeze where i couldnt wake my phone using power button, nor plugging in power cable light up the screen for charging, and long holding power button couldnt turn on my phone either (my phone was on before with 7x% remaining so i dont think i ran out of battery..)
had to pull battery and put it back in for it to work again.. anyone with me?
if it happens again im going back to M1 to see if it is becos of m2

That sounds like a SoD, you using Hotplug mod? If so, try without for a while...

Hi,

Firstly loving the battery life! but I enabled the bootanimation and now can't change it back using either 'Boot Animation Changer' or 'Boot Animations'. I've unticked the box in the kernel updater programme and tried deleting the zip file on system/media (which refuses to delete or rename).

Any ideas?

You need to replace the bootanimation.zip in /data/local.

You will get instances of the battery going up slightly, this is due to the reporting interval - the handset makes estimates between reports so can be slightly off if it goes from decent usage to idle...

Hi Francisco

Using M2 and no problems whatsoever. However, i just happened to glanced at the changlelog and you mentioned no more blueish color but when i input your suggested values for Gamma (-4,0,5). Everything goes blueish. Also, i am using your recommended RGB values

Just wondering. Thanks

I dunno but to my experience it depends on the rom u are using. Gone through 4 diff kinds of roms. Aokp with francos settings has is a tad on the blueish side. Liquidsmooth abit of blue as well. Im back using modaco now and the color is just perfect with francos app/color settings. I dunno maybe its just me. :D

    I hate big OPs.

    Works on all roms. r390 and newer versions are ONLY for 4.3 or newer.

    F.A.Q:
    1. My device rebooted or crashed, how can I help?
    A: Get me /proc/last_kmsg on pastie.org.
    2. Battery sucks, my device is not entering deep sleep. FIX PLOX!
    A: Fix it yourself, it's an app waking your device up not the kernel's problem
    3. Signal is dropping since I flashed the kernel, amg u sucks!
    A: The kernel has nothing to do with gsm/cmda signal. Make sure you have the latest radios
    4. Do I need to wipe anything when flashing this kernel?
    A: No.
    5. Does this kernel has X or Y mod?
    A: Learn to read, everything you need to know is in the features list, changelog or public repo.

    I got these from that thread:

    so it makes much sense, to make the min_sample_time as low as possible (?), but how low? what's the most appropriate sample time for battery and performance?

    for the timer_rate, franco suggested 30k to consider the CPUs latency. What has it to do with the cpu's latency?

    he also said min_sample_time doesn't have to be in multiple of timer_rate.
    in my case, all my timers are in 20k, which works fine as of now. But i must be missing some things, because I just saw somebody post these values, and no detailed explanation for having them.
    Click to expand...
    Click to collapse

    Yes and no. Here's what we're thinkin' so far.

    THIS POST WILL BE A RECAP OF THE LAST FEW PAGES OF RESEARCH! :)

    This was my original settings that I've been using for weeks:
    above_hispeed_delay: 20000
    go_hispeed_load: 50
    min_sample_time: 40000
    timer_rate: 20000
    Click to expand...
    Click to collapse
    So to make the short hand easier, we kept it in that order and just said: 20000/50/40000/20000 became 20k/50/40k/20k became 2/5/4/2. Make sense?

    Here is a breakdown of what they each mean:
    -above_hispeed_delay: Once speed is set to hispeed_freq, wait for this long before bumping speed higher in response to continued high load.
    -go_hispeed_load: The CPU load at which to ramp to the intermediate "hi speed".
    -min_sample_time: The minimum amount of time to spend at a frequency before we can ramp down.
    -timer_rate: Sample rate for reevaluating cpu load when the system is not idle.
    Click to expand...
    Click to collapse

    This is a good explanation that I wrote back on page 3038:
    -above_hispeed_delay: higher = better battery, lower = better performance. (100k is default)
    -go_hispeed_load:.......higher = better battery, lower = better performance. (50 is default)
    -min_sample_time:......lower = better battery, higher = better performance. (60k is default)
    -timer_rate:.................higher = better battery, lower = better performance. (20k is default)
    Click to expand...
    Click to collapse
    So Google's default is 10/5/6/2. Lower numbers are all better for performance except min_sample_time (there higher is faster). So our goal is to find a sweet spot.

    The default 10 is for "Once speed is set to hispeed_freq, wait for this long before bumping speed higher in response to continued high load." So we think 10 is too high, but if you go too low, then you'll be using the higher freqs a lot more than you need and it will hurt the battery. So we are leaning towards 6 (60000) for above_hispeed_delay.

    The default 5 is for "when the CPU hits X% amount of load, then jump to the hispeed_freq." Again if this one is too low then it will cause the higher freqs to be used more often then they need, so we actually turn go_hispeed_load up a little bit to 7 (70).

    The default 6 is for "how long do I wait before lowering the clock speed from what it's currently at." So the lower we put this, the better battery will be. We're still trying to decide between 3 (30000) and 5 (50000). Osm0sis is getting more lag at lower levels, and finds the best performance mark at 5. So we turn min_sample_time down a little from stock to help with the battery.

    The default 2 is for "wait this long before changing the clockspeeds from what it's at now." While technically 2 sounds better because it's changing more often, Franco believes that by setting the timer_rate to be the same thing as the CPU sample_rate (which is preset at 30000), then that will make the CPU more efficient at switching. So we increased it from 2 (20000) to 3 (30000).

    So TO RECAP: Using the stuff from above, Google's defaults for these settings are 10/5/6/2 and we are changing them to 6/7/3/3 or 6/7/5/3 (again, still testing that third number for the min_sample_time).

    Does that make sense for everyone interested in following along? Any questions? Feel free to try out these settings yourself (the easiest way is with Franco's app or something like Trickster). We want as much feedback as possible on this.
    The next kernel release will have the totally tweaked settings for everyone to test without having to change their own stuff.

    Kernel Emergency Settings Reset Zip

    Alright so here's something that's been requested for awhile.

    I wrote it up recently with Franco's stamp of approval, so I'm posting it here now. Please direct people back to this post from other threads.

    This can/should be everyone's go-to when experiencing problems after updating to a new kernel build, you get stuck in a bootloop, or you think there's a conflict between ROM and kernel (or kernel tweaking app) you can't track down, since likely some leftover settings (voltages, etc.) are at fault. It's also useful if you just want to make sure you're running clean defaults. This should work on any device franco.Kernel and f.Ku support, as well as a variety of other devices, kernels and control apps: eXperience (Free/Pro), GLaDOS Control, TricksterMod, Trinity Kernel Toolbox, ROM Toolbox (Lite/Pro), SetCPU, Faux123 Kernel Enhancement Project, Performance Control and Synapse.

    Flashing this via custom recovery of your choice will delete the kernel app settings file(s), disable init.d and userinit.d scripts by moving them to a subfolder (/system/etc/init.d/off/ and /data/local/userinit.d/off/ respectively) and wipe cache and dalvik-cache for good measure.

    Hopefully it helps!


    Note: If your ROM has a Performance/Tweaking App built-in you should also manually disable any Set On Boot options it has. For example, I couldn't include clearing CM's Advanced Settings since they're built into the main com.android.settings/Settings.apk along with a lot of other Android OS settings (APNs, Developer Options, etc.), so to run clean and without conflicts on CM you need to unset them yourself.

    You should also avoid having more than one control app installed at a time. Conflicts have been reported even with everything "unset" in two apps.

    I also chose not to disable anything your ROM may have in /data/cron or /system/addon.d since some rely on it heavily, so you can choose to review those directories' contents and whether you want to leave them enabled on your own. I also left out disabling sysctl.conf since that's done by f.K and the Franco's Dev Team scripts, and also seemed a bit heavy-handed for this zip script.

    There are some battery savings from UVing but they aren't extreme. If you do not know how UVing works and/or you can't/won't read to properly build your own voltage profile, then just stick with the defaults Franco has already UVed. If you do still want to learn to UV then, once again, everyone should build their own voltage profile for their own device. Read this, this, this, and this for starters on UV methods. You don't know how your device will do until you learn and try.

    As a sidenote, if anyone else wants to share their voltages for comparison the easiest way is to copy the contents of the 3 voltage files (mpu/iva/core) in /sys/class/misc/customvoltage/ - they look (almost) exactly as the sections above.
    Fsync on just in case anything ever happens I want my data protected. That said I do disable it temporarily if I ever want a bit more performance in an app or game. SR is hardcoded disabled in the latest builds.

    The other thing worth noting is I set my color settings on boot with an init.d script. Doing it that way you can end up with a completely different result from the same values. The contrast, blacks and colors are much more natural. Also it's seamless which is nice; they take effect during the Google logo. Attached is my init.d script for that. Alter it to your own color settings, remove the .txt extension, push to /system/etc/init.d/ and set the correct perms; rwxr-xr-x (chmod -R 755 /system/etc/init.d in Terminal Emulator).

    900colorsettings can be found with my other init.d scripts (from Franco Dev Team), here: https://s.basketbuild.com/filedl/devs?dev=osm0sis&dl=osm0sis/scripts/900colorsettings

    Note: On my new replacement screen, setting the color multiplier too early in the boot (any time before the boot animation) made everything look dark, oversaturated, uncontrasted and dusky; basically the opposite of the way it used to work on my old panel. Adding sleep 2; before that line in the init.d script fixed this, so experiment if your panel is more like my new one, and the init.d as-is after you put in your settings makes it look worse.

    [ New init.d script with my new colors. I need the sleep 4 because of my problem in my "Note" above, so comment it out if you don't need it, it will make it look worse. Previous download counts were 1880, 646, and 307. Thanks everyone! ]
