I just dont think that there´s much difference in

your

case in relation to the stock kernel. I dont believe that there is that much difference in standby-time between them.

In my opinion, the kernel gives a very good balance in performance and energy saving. It´s faster than stock and has reduced battery consumption. And this, plus the extras, are the main benifits of a custom kernel - not the standby time.

I dont want to offend you, just wanted to clear things up.

1 thing we have in common: It´s definitly a great kernel.

Hello slim80! First of all let me say I have been enjoying your work since iB4STiD left us, really great stuff. Since the 2.2 update I have been dealing with an issue where apps including Kernel auditor and faux sound are not recognizing headphone gain as an option (2.1 they did). However, I can still increase the volume, but it will reset back if I turn the phone to loud mode, or receive a notification on loud mode. Any ideas?
[Galaxy S 4 i9505 Android Development] slim80:
You have to use STweaks for the sound controll
[Galaxy S 4 i9505 Android Development] xell75:
I have a strange bug after set from MPDecision to Intelli-Plug, everytime I charge my phone, everything seems freezed after a couple of charging time. (No charging procent updates or time updates anymore and when I open an app, the screen remains blank and it won't open) The only fix then is to do a full reboot for this. But after changing back to MPDecision, the bug seems gone, never had this in earlier versions of the Kernel.
[Galaxy S 4 i9505 Android Development] radz_:
I always use Intelli-plug, i never had issues with it..
[Galaxy S 4 i9505 Android Development] vman10:
Thanks [MENTION=4543502]slim80[/MENTION] for the great kernel.

I am getting good battery with Imperium ROM LL v9.

Over the past day, I used little mobile data, some wifi and no games. Apps used are shown in the screenshot and I easily managed over 4 hours SOT and still had plenty of juice left. When I was playing games that also required internet connection, I would only manage just over 2.5 hours SOT. There is no "perfect" kernel settings. The kernel is good as is but I did change a few settings (nothing major).

STweaks changes:

- Reduced CPU voltages by one step on all frequencies

- Reduced GPU voltages by one step on all frequencies

- USB charge up to 700mA

- Disabled Android logger

Everything else is untouched

Also note: Not using Greenify, Xposed not installed, Calendar Contacts Drive Gmail Keep and People are set to autosync, Air Gestures and Air View disabled, Date and Time set on manual, not sure why battery creeps up during deep sleep and maybe some other settings..
[Galaxy S 4 i9505 Android Development] Calaisz17:
Why everytime i open stweaks its empty? Says kernel not supported?
[MENTION=4543502]slim80[/MENTION] just looks like picture attached? Nothing there?

Anyone got a link to stweaks maybe try re instal
[Galaxy S 4 i9505 Android Development] Calaisz17:
Link to latest stweaks apk please anyone?
[Galaxy S 4 i9505 Android Development] radz_:
Latest stweaks already comes with this Kernel mate .

Try to reflash the kernel.. download in 1st page
[Galaxy S 4 i9505 Android Development] Calaisz17:
yeah its a bit odd. should i try unpack the kernel and put stweaks into priv-app manually?

i have done a few times the 1st time itll show then after reboot its just blank? any ideas mate?
[Galaxy S 4 i9505 Android Development] radz_:
Have you tried to flash Kernel Cleaning script then flash the Kernel again?

Usually that issue cause by busybox not working properly.. but by flashing the kernel again it should fix the issue since the zip file comes with busybox..
[Galaxy S 4 i9505 Android Development] Calaisz17:
yeah that and hawkerwipe will try again tho thanks mate. should i leace the stweaks app by itself in oriv-app or make a folder for it?
[Galaxy S 4 i9505 Android Development] radz_:
Hmmm thats weird... same thing if you flash the zip, stweaks will be installed in priv app...

What ROM are you using?
[Galaxy S 4 i9505 Android Development] slim80:
Check if you denied the SuperSU permission
[Galaxy S 4 i9505 Android Development] xell75:
Whenever I change the voltage of the cpu/gpu, is it set instantly after click on apply in stweaks or do I have to do a reboot?
[Galaxy S 4 i9505 Android Development] JASONRR:
The no kernel support in STweaks is due to permissions not getting set in the /res folder when you flash directly over exisiting kernel not having STweaks suport. Formatting boot manually before flashing the kernel fixes it.
[Galaxy S 4 i9505 Android Development] w3nZ:

[Galaxy S 4 i9505 Android Development] Jimmy Mossiba Floyd:
does it need reboot??
[Galaxy S 4 i9505 Android Development] Seth25:
Could you guys recommend some settings for a performance oriented setup? Thanks!

Battery is important, but I want a smooth rom first. Thanks!
[Galaxy S 4 i9505 Android Development] xell75:
It seems it doesn't need a reboot, I found out myself. And I can confirm yet, even 2 steps undervolting of cpu and gpu seems to be stable, eats less battery, same power and with dvfs disabled in combination, it's an good performance boost. And because of that undervolting, my cpu heats up only to 60 - 65 degrees celsius, not 80 - 90 as before while playing heavy games such as Chaos Rings 3 (with dvfs disabled) I'm using the great Rom S6 Port v3.0 by Albe95
[Galaxy S 4 i9505 Android Development] Seth25:
Whenever I disable DVFS my phone is charging excruciatingly slow... is this normal?

Same problem on KK and LL.
[Galaxy S 4 i9505 Android Development] xell75:
I don't know what's wrong, but I don't have this problem, my phone is charging full in less than 2 hours with dvfs disabled, no change at all. Maybe it's some app that eat the battery more in background?
[Galaxy S 4 i9505 Android Development] Seth25:
Thanks for the answer, definitely no app is doing this, since all I am doing is enabling DVFS or disabling it. Had the same problem on previous KK ROM and it seems to persist on latest Imperium LL ROM+Kernel.

How to disable DVFS?
[Galaxy S 4 i9505 Android Development] HITMAN-CREED:
Using Xposed & Wanam Xposed
[Galaxy S 4 i9505 Android Development] hubciopl:
Ok. But there is any other way not using Xposed and Wanam.
[Galaxy S 4 i9505 Android Development] HITMAN-CREED:
Wanam introduced DVFS for the first time and made an option to disable it..

So the only way is using Wanam Xposed.
[Galaxy S 4 i9505 Android Development] hubciopl:
Big thanks. So install Xposed & Wanam

[Galaxy S 4 i9505 Android Development] :
Hi,

Was trying to get a picture of the battery usage screen but to be honest do not know how as I am new to this phone. Will search for that option and update as my next battery cycle winds down.

I am a basic user spending most of my time on WiFi reading news - watching Youtube videos, etc. I use this more as a basic phone.

Thanks,

Wow 5hrs SOT :( I can't even reach 4hrs yet (currently 3hrs + some minutes) , is your device new? Btw, I'm from Montreal too!! :D
[Galaxy S 4 i9505 Android Development] :
Hi, phone is relatively new to me - picked it up about a month ago (build date is Sept 2014)

I've had some pretty crappy phones with older versions of Android that often had apps that remained active, drained battery, etc - so I found work arounds and ways of improving battery life. With these kernels and the ability to alter them has appeared to only increase these work arounds.

For instance, I do not use the Facebook app - I find it to be a pig, and usually remains open and active even after closing. I use the mobile address on my web browser instead. No lag with the browser, appearance wise - the mobile address looks the same as the app, so for me it's all good.

I close WiFi and Bluetooth if not in use - and with drop down toggles, this is relatively easy. I suspend all sync operations since I have a very limited data package, it serves two purposes. I do not waste data - and apps are not trying to sync in the background.

On this phone, after much reading about newer versions of Android, decided to remove all battery saver apps, task managers, etc and let the OS take care of itself.

I'll post up some screenshots (now that I know how :)) as the battery drains down.

Thanks,
[Galaxy S 4 i9505 Android Development] xell75:

[Galaxy S 4 i9505 Android Development] stevtec86:
Thanks for update!

Thanks for Report!

My Opinion;

Just installed the V2.3 after the Kernel scrip cleaning 1.9! All fluid! Great job as always.

The only flaw (personal taste), I preferred STweak Material Design. It is possible to have him back?

Why you prefer Revert STweak?

Edit: The new Governor "Barry Allen" that features? is better to fluidity, performance or BatteryLife?

[Galaxy S 4 i9505 Android Development] kfallz:
I think I actually prefer this stweaks, it fits a lot more into less space, don't really care about the design :)

One thing I don't like about stweaks, at least the versions I've seen, guess you could program it in there, is that it doesn't have "decrease/increase all cpu steps by 25mv (for example)"

[Galaxy S 4 i9505 Android Development] Buckycasuals:
[MENTION=6396069]Nana Ayeh[/MENTION] It's based on interactive. A cpufreq governor for latency sensitive workloads. The gov was created to be more battery friendly + good performance. The gov itself was created by [MENTION=3794588]javilonas[/MENTION], although he is not very often on xda.

For more smoothness, use with sched - FIOPS.
