I don't use CM 10.2, but JB variant of ROM. Just waiting patiently for the new release and see what happens.

---------- Post added at 08:47 PM ---------- Previous post was at 08:43 PM ----------

It could be the radio driver of 9195L. You just need to wait for the new JB variant kernel and see if it will fix it for you.

As for battery saving governor, generally ondemand/interactive works for the JB variant of F4k's kernel.

Thanks for your reply.

I hope the creator takes note of this so I could use this great kernel.

Hi,

I'm using "SetCPU" for VC and it works fine.

But I've realized that "Performance Control" does not work for VC manipulation.

My config: i9195, CM10.2.1, F4k 1.3.0 JB lte kernel.

I bought a 3800 mAh Akku for my device but the kernel "expects" 1900 mAh this is why I'll have to reboot if my device says the akku is empty and then I'll have ca. 50% again. So can anybody please tell me how I can change that the akku expects 1900 mAh so that I havn't to reboot my device?

I've got the same issue, battery "dies" but after I reboot it shows between 40-50%

I've ordered a zerolemon battery for our device, it's still in transit as it's being sent from America to United Kingdom.

No doubt I'll experience the same minor issue, however I'm not sure if this can help but I installed Android Tuner, which I've now uninstalled because the reason I installed it for I no longer need.

I did see an option in there to change the battery mAh, but I be honest, I was too afraid to try it seeing as I was in a hurry at the time and had no nandroid backup, I think it was in the battery tweak option somewhere...

You can try this if you like and report back on if it worked or not?

As mentioned before by myself in previous posts, "calibrate battery" there's a app in play store that does this, you need to empty your battery down then change the mAh, then fully charge the battery then calibrate it

how did you apply -75UV? I was trying with PerformanceControl by f4k but it seems it doesn't change voltages...
[Galaxy S 4 Mini Android Development] Grobie13:

[Galaxy S 4 Mini Android Development] coldgin_:
Hi,

Im using Android Tuner Free, you can download it from Play Store.

With this tool you can hack cpu, gpu, kernel, etc.

Like the other user said, Trickster MOD works just fine to do the same.

UV -75 is the max I tested as stable, but it depends on a lot of things like programs running, screen brightness, governors configuration, etc, so the energy your device needs to work will limit the UV you can set up. If you run into several reboots a day, you have to UV less. And if you are overclocking your cpu, forget UV .

Hope it helps!

You've posted in multiple thread and even started a topic on this issue, including more than one post on this very thread. You don't have to raise the issue multiple times to get the attention. Nor it will happen just because you so persistent on multi-posting. In the very own thread of that post, the modder even mention the risks. If it can be done, it will be done eventually.If you want it so bad, try modding it yourself as the modder did indicate what to do. Stop trolling please.

[Galaxy S 4 Mini Android Development] Whosat:
Post #2 tells you that you have to do those listed actions to enable those kernel features. The default values that come with the kernel are the same as before you flash the kernel.

To OC you need to raise the maximum clock speed by flashing one of the hardlimit zips, otherwise it stays at 1.78ghz

To fast charge via USB you need to use one of those commands to change the maximum charging current otherwise you will charge at the usual speed.

Same question here. He tried it on KitKat Pac-Rom. I tried it on 4.3-based Pac-Man with f4 JB kernel and it wouldn't boot neither (yet it worked on the old JB Carbon from early November).

It would be nice to have some alternative on Pac-Rom because the stock kernel is not very good.

Hi [MENTION=3261191]F4k[/MENTION], CM 11 nightlies for the S4 Mini have recently been updated to detect appropriate model numbers for differing variants of the device and thus custom kernels need to be updated to use the new init.

FauxSound

Hi, I downloaded it from the Play Store and worked as it should. It's a paid app, with no free "ads version" options nor trial period.

So if you can't download it from the PS and you found it in some other place, just be carefull that its not a trojan.

The same this app does can be done with Trickster MOD app, but I'm afraid that you need the paid version too.

The power supplied by your power adapter is used to run the device you attached to the USB-OTG.

This is because the phone does not supply the power to the device so you need the OTG-Y cable to use an external power source.

[Galaxy S 4 Mini Android Development] Phenom2122:
Thank you very much! I wasn't sure exactly which files would be needed and if it would differ at all from the last one. I use the 3G version so I repackaged your zip with all the same files from the 3G Carbon.. Tested and working.

I assume the kernel within any rom will always be the same folders?
[Galaxy S 4 Mini Android Development] GNUDroid:
at least for all cm11 based roms it should be always the same folder structure.

but we always have to be careful because (rarely every some month) it could be that other libs in the rom changes (like graphic libs) then it will not work to fill an old kernel-zip with the new corresponding files.

to the honor of the dev: normally we should wait if f4k is OK with repacking his kernel from an maybe newer ROM of himself by us users?

hi !

i have generaly noticed a big problem with F4k kernels ( AOSP ,and stock too ) :

i assign one of the governors like smartassV2 ,H3 ...etc ...with "performance parameters for customs and "no-frills" for stock , i use the phone for a period and i decide to look with "CPU spy" the frequencies variations :

=> i see that the cpu is near to always want to going to the "max" frequency

and stay on it when i use the phone

!!! incredible ! it seems that all governors look like to "performance" governor (the same things) !

And it suck very much baterry compared to original kernels (CM and stock) ...logic ! : always to the "max" ... only going to "deep-sleep"

(it's impossible that all apps need to have a very big power with 2 x 1.7 Mhz ! )

[Galaxy S 4 Mini Android Development] impactor:
It only affects your battery life when the phone is doing nothing, because it does not let it sleep, or even downclock. Get a program like Android Tuner or System Tuner, and check what is the offline time of your processor. Because of the governor flaw of those kernels, it should be around 0.

BTW, how is the weather in Marseille? I wonder if it's time to pack and move there already.

Hi !

try using Intelliactive governor, it works just good, much better than smartass-es, interactive, etc. With those I had the issue you said too, but with Intelliactive had no problems at all it scales very good and got impressive battery life (2 days with normal use, using sioplus as IO gov) because it goes to lower freqs as like you said no apps need high freqs all time. And the phone deep sleeps as expected.

a quad-core,it's the same as dual-core i think but more amplified.......in managment, compared to the mono-core .

"row" would be very very great for a quad-core !
