You can try setting the voltages individually for each state. I can lower the voltage at 384 MHz by 125mV and at 1GHz only by 75mV. So there still might be some room left for improvement. Just do it slowly and check for 1-2 days if everything is ok. Took me a few days to find stable settings. Just be careful and don't overdo it, because lowering the voltage by too much, might cause data corruption. I've already seen this after 2 reboots when testing.

As for governor: It depends on what you want to achieve. If you wan't to get the best possible battery life, you can try the same settings I posted earlier: http://xdaforums.com/showpost.php?p=41815734&postcount=832

With the governor set up like this, it won't change clock speed so often and not always jumping to full speed. But still, when you touch the display, the clock speed is set to 1,1GHz so there's no lag and I don't have any problems with performance (see attached benchmark scores).

You can change the settings as you need them, but I think 1,1 GHz with quad-core processing is more than enough for daily usage (even when playing games, as the GPU is the limiting factor here). Samsung is limiting the CPU in Eco-Mode to 1,35 GHz.

I get incredible battery life with these settings: With light usage, around 1 hour screen on time, 30 minutes phone calls, auto sync google (gmail ~30 emails per day, contacts, calendar) and 3G only, I get around 4 days out of one charge. My SGS2 or LG O4X only managed 2 days with the exact same usage pattern. 2 days with heavier usage is no problem and even with nonstop touching the phone I have no problems getting through the day. :good:

AnTuTu overrides the max clock speed setting. So it sets the speed to 2,1 or 2,2 GHz depending which kernel you are using. Not all phones can handle that all the time...

I'm wondering if you got a bad download, I had that problem with Chrome and when I used Next Browser it didn't happen again but that's what it sounds like.
[Galaxy S 4 i9505 Original Android Development] Mebborne:
Thanks, but I don't think that's it. I've tried multiple ways to download it. The strange thing is I had downloaded and installed it on a different ROM using the same base a couple of days ago without issue. The only difference I can think of is I'm using a different recovery. I was using CWM and now am using TRWP. Do you think it doesn't like TRWP or do I need to do something different in TRWP? I'm just wiping cache and dalvik and then flashing. Thanks again.

Thanks for the reply Faux123! I really enjoy your kernels. Came over from the HTC Sensation. However, the downloads I had match exactly whats on your server, so I don't think that's the issue. I don't know why it keeps failing on install. Do you know if your kernels don't play nice when flashed with TRWP recovery? Don't know why that would be the case, but that's the only change I can think of that I have made. Thanks again. Mebborne

Interesting. Well, I guess it must just not like the ROM I'm on. I'm currently on this: http://xdaforums.com/showthread.php?t=2274795 It's basically just a slightly modified stock ROM. Since it is so close to stock, could that be causing some problem? Thanks.
[Galaxy S 4 i9505 Original Android Development] Orical:
The tough part is I can't recreate the problem on my end so trying to fix it is just blind guessing but I had a problem a long time ago with TWRP on another device where I had weird errors using it and had to flash CWM first to have something to use for the rest of this so that's important and go to the SDCard and delete the folder labeled TWRP (sdcard0/TWRP) and also if you have one installed (EXTSDCARD/TWRP) but before you do make sure you move any backups to another folder first, I chose Downloads in EXTSDcard. Then go to Goomanager and hit menu and hit install openrecoveryscript, this will install the latest 2.5.0.2 but more importantly it will install the correct folder/files that needs to be there, it's a weird problem that very little users have but just deleting the files in the TWRP folder wasn't enough for some reason but the one file was for the build and wouldn't change when it was updated so it created problems in backups and flashing as it checks it before doing anything.

EDIT: That's the ROM I'm on as well at the moment but TWRP works fine here.

I'm not sure this will be the problem or not but that's what happened to me and that's how I fixed it. Hope that helps.

[Galaxy S 4 i9505 Original Android Development] allandacruz:
Are you talking about Touchwiz launcher? If yes, forget it! It's a crap, heavier launcher I've seen in android world since my first device (I9000).. Handle the heavy by default Touchwiz launcher on 1080p screen will lag independently of kernel or SOC..

Now look other things, I doubt that your note 2 is faster than s4 in Multi View feature, on web browsing, games, and other things that requires CPU power...

[Galaxy S 4 i9505 Original Android Development] Sammath:
Actually no, I never use touchwizz I always use nova or next 3d.

The note 2 was oced to 2ghz. Never had any stutters or lags or whatsoever.

Games require gpu power actually more then cpu, don't know where you get that from. Yes the s4 has a much better gpu anyways.

But the feel of it was allot smoother than the s4.

The s4 needs more fixes and newer smoother firmwares.

Ever had a note2? If not, you don't know what you are talking about.

This kernel makes up for a lot of the problems the s4 is suffering from tho.

If the game is not optimized for our Adreno it wont use the GPU at all..

I've had one Note 2.. I bought with one week cause I can't handle this big size phone..

Ok, you overclock it.. and note 2 has a 720p screen, it can make difference..

I've been using faux kernel (no overclock - -12.5uv) with omega ROM.. this combination is super smooth.. can't notice any lag.. maybe you need try omega 3.1..

I love the S4 audio with this driver by faux, I think it can be equal to IPhone 4S audio (don't hate me cause I said that)..

I'm not on a full stock rom tho, already tweaked the swizzle out of it myself a lot of build. Prop tweaks etc.

Having this kernel is the best what's happened to this device :)

[Galaxy S 4 i9505 Original Android Development] faux123:
This reset of max frequency is triggered by stock thermald when temperature throttling. So if your phone is running cool all the time, this will never happen to you.

Flashed the fix but sampling rate still not sticking. Anyway, love the kernel Faux!
[Galaxy S 4 i9505 Original Android Development] faux123:
Sampling rate is not an issue. the problem with it not "sticky" is due to its dynamic feature ;)

While Screen On with NO TOUCH inputs... it will sample @ 50K

While Screen On with TOUCH inputs.. it will increase it to 15K for 3.5 seconds to give you that buttery feeling ;)

While Screen Off, it jumps to 300K to save battery ;)

So when using fauxclock, it will read the 15K always since you have to touch it :D Don't worry about it!!!

[Galaxy S 4 i9505 Original Android Development] hiazn:
Quoted from Opening Post....

This is due to LACK OF SOURCE CODE from Samsung/Microsoft for exFAT. Samsung licensed Microsoft's CLOSED SOURCE exFAT implementation. But Samsung under agreement with Microsoft DOES NOT release the source code :(

[Galaxy S 4 i9505 Original Android Development] faux123:
yeah.. if you formatted to NTFS.. that's why my OP highly recommend formatting to FAT32 and be done with it. FAT32 is recognizable by recovery as well.

Until a fully working FUSE based exFAT is ready or Samsung/Microsoft (MS primarily) decide to open source the exFAT, FAT32 is the next best thing.. (it just waste a bit more space due to larger blocks).

exFAT's only advantage is the ability to use smaller blocks for larger than 32 GB SDCards.. it is just more efficient use of space if you have TONS of small files. If you have lots of larger files like photos, than exFat and Fat32 are almost the same. (FAT32 is universally supported, exFat is not).
