Use CPU Spy or Android Tuner Free to see how all 4 cores are doing. Perhaps there is a rogue application that locks the CPU to the maximum frequency...?

@ktoonsez

If I select BFQ, go to "I/O Scheduler adjustments" and scroll all the way down... well, just have a look at the very last line.

It's nothing major, obviously. BFQ is the only scheduler this happens for, since it is the only scheduler that has so many adjustment settings, I guess. Still, perhaps this is a more entangled issue, more prominent across the board than it appears to be.

Hey ktoonsez and community,

take care of 4.4.2 leak. I heard with it comes again a new Bootloader, that can brick your Device. It will check of original Software and set an Efuse. I heard of it, i can't prove it.

So take care pls.

I'm on latest kernel and had really strange event at the middle of the night.

Woke up and phone screen was going on and of on its own. Blue led was blinking. Don't know why.

I unlocked my phone and was really laggy. Then I just lock it and leave it alone. Now it's working OK.

Anybody here that can move apps to the external SD? After flashing the kernel, all my apps that was moved to the external SD are now unreadable. Even bards tale(game) tells me to download data again to the internal storage. Though in the settings I can see that my external SD is mounted, and I can see its contents in esfileexplorer. Gallery also sees my media in the external SD.

[Galaxy S 4 i9505 Original Android Development] rauschkugl:
Moving apps to external SD is supported since mea so if you flash a kernel that hasn't mea sources you probably could lose this function. And mea sources aren't released until now so you have to stay on stock kernel or use foldermount.

But I don't know if there's something in the kernel for app to SD. Could also be another problem.

Awesome, I just cut and paste the script into the ktweaker script I am using and now fast charge is enabled on boot - happy days :)

I am now trying lateralus script with Lucretia profile and everything feels smooth and fast but I can see that the cores are ramping up quickly when needed and hotplugging and shutting down quickly also - battery drain looks reasonable so far and also when using nav I see a small charge going in rather than discharge without messing around with power save governor for GPS (which I have found is floored as soon as you get a call whilst using nav).

For me I think this set up is definitely a keeper! Too many good ones to choose from though lol!

I was having similar problems with some settings from KTweaker Shop. The phone sometimes did a soft reboot and I lost the data for a few apps (not all). In the end I solved it by setting stock voltages to CPU stock -50mV and GPU stock -75mV and it hasn't happened since.

[Galaxy S 4 i9505 Original Android Development] Formhault:
Ah, I see. That's my setup, as well :D. Guess it's pretty standard, as I see KT has this in his profile as well, and many others, I bet.

Back in the days when I had time (like 3 months) to test, I remember I managed to go as high (or low?) as 100 milivolts for the CPU, and 75 for the GPU. Or the other way around... Anyway, I forgot the exact values (could be 95 instead of 100) the moment I jumped ship to KitKat, because apparently the same ones that were stable for SlimBean were not stable for Android 4.4 ROMs, so I started from scratch. :(

Regardless, that doesn't seem to be the case anymore, as my phone now randomly reboots when I starve the CPU 25 milivolts pass this 50 mV threshold. :confused:

---------- Post added at 04:24 PM ---------- Previous post was at 04:22 PM ----------

I'm not too sure about that...

There's this very intensive game I play, called Arcane Legends. I tried overclocking the CPU to 2 GHz (sowwy, can't go past that point while maintaining stability) and the GPU even up to 600 MHz (at least for the short time in which it DIDN'T cause a crash)... and guess what... the game still stuttered every now and then, and the frame rate wasn't as smooth as on a Galaxy Note 3 (where it was lightning fast).

EDIT: Oh yeah, I didn't think about changing the I/O scheduler to ROW. But even so, I doubt it would have made a difference and add the 3~7 extra fps that game needed to be smoother :).
[Galaxy S 4 i9505 Original Android Development] Mussels84:
-65 cpu / -50 gpu here, i find that at higher undervoltings on various phones, it works fine on a full charge but can get unstable as the battery hits lower voltages.
[Galaxy S 4 i9505 Original Android Development] Formhault:
Really? Hmm, that's interesting. I don't see any reason why the CPU would behave like that at lower battery levels, since the battery is supposedly able to deliver enough power for any conditions, so even overvolting a bit should not cause issues. Undervolting should make the battery stress less when it comes to power delivery, so... it really should make it easier :confused:
[Galaxy S 4 i9505 Original Android Development] Mussels84:
i've always assumed that the circuitry that changes the voltage from the battery to the CPU/GPU isnt perfect, and fluctuates a little - so your phone could be stable at -75mv but not at -80mv, and going to heavy load could cause it to droop to that for just a millisecond too long.

i've seen that kind of behaviour in PC's (my main hobby) and its called Vdroop, so it should apply here as well.

edit: i definitely saw this on my galaxy tab 2.0, it OC'd stable to 1.4GHz, but would freeze randomly - and i realised only when OC'd, and under 30% battery. upping voltages made it stable.
[Galaxy S 4 i9505 Original Android Development] Chelonee:
Noticed that, too. As soon as my phone hits less than 15% battery left it gets noticably laggier. Only reverting the voltages to stock helps.
[Galaxy S 4 i9505 Original Android Development] s3icc0:
Don't forget that there is a CPU Throttling limit!!! (in KT kernel) So too much OC can cause the phone will actually go slower ... you have to test your piece ...

But the logic is clear:

- use the most performance focused governor - which is performance (and you can make tuning to it as well in KT)

- use the most read focus scheduler - which is 100% row ...

- use most power you can get from the phone - OC GPU and CPU ....

- don't forget to check stability and limits of your device .... and along with your UV it may also cause problems ...

So I think I am 100% right this time :)

---------- Post added at 04:22 PM ---------- Previous post was at 04:19 PM ----------

check the Battery Mhz Control under Extras menu in KTweaker .... for no difference on low levels the settings should be: 0 0 Disabled Disabled Disabled

Vdroop may be the issue as well as with lower voltages settings the change in Vdroop will be almost not change so finally you are not giving enough juice to the phone.
