I never asked about anything. I jumped in because a bunch of clueless people, who are jacking on other super battery saving techniques attacked a guy who asked about killing apps feature.

MPU runs the code, but that code has to be in RAM. When one kills the app, removes it from RAM, it will instantly stop working, and stop consuming power. Now, I never said this is a super solution, and it will double your battery life. But neither the hibernation will. I was running greenify for a month to test it, and I saw no improvement. All this is about apps which misbehave, and user habits, and his behavior, what apps one uses etc.

Regarding RAM again, for example Samsung suggests removing apps from recent apps, thus from RAM, to save the battery. But never mind. People who are not aware that app has to be in RAM to be executed by the CPU, what means, purging app/service /process from RAM will stop it executing, have no clue about the most basics of this arch.

the best kernel out there :) just my suggestion, can you please update the UI of KTweaker? like in Extras, its dirty in my eyes. STweaker or Trickstermod has nice UI. its ok if you dont want, just my suggestions :highfive:

That s really a personal opinion.

I really do not like the STweaks interface. Talking about hurting my eyes, now there is an example :D

It's impossible to please everyone.

Actually I also have incoming call lag.

I'm on aosb 4.4.2 probam.

I've searched and couldn't solve it.

Also setting super conservative to 0 didn't help.

At the moment I use ktoonsified v4 profile with ondemand governor but I really wished I could figure it out because ktoonservativeq is really awesome...
[Galaxy S 4 i9505 Original Android Development] !crazy:
Could someone point me to the location of GPU configuration files?

Has anyone noticed anything strange with simple GPU governor? For example with efficient kernel, which is based on KT, other apps like faux clock and trickster mod, recognize the governor and offer the configuration options, but that's not the case with KT kernel. Faux clock shows only performance and ondemand, and Trickster too doesn't give any configuration options for simple...

You might wanna set "Screen Off Profile Mhz" to "Selected Scaling Max" (basically, no custom screen off frequency).

Side note: I discovered that even setting it to a pretty high frequency (like 900 something MHz) is not enough... Looks like the screen needs >1 GHz processing power to come online fast.

Disabling that suddenly made the problem go away for me. Anyway, the screen still goes on half a second after the call actually comes in, but I doubt we can eliminate that...

I've tried many different settings with different governors. But Ktoonsez for governor! Lol. It's simply the best governor for all around performance :) Gaming, browsing etc. Strongly recommend KTGaming even running for everyday use. I tested a battery saving profile, didn't see much difference, maybe 2-4% more battery consumption.. But its no big deal.

Tried it, didn't change a thing. It isn't the WiFi itself that's slow it's Internet access.

On my local network (pulling files from the server) I'm getting a constant 4.5 Mb/s but downloading from the internet is sometimes around only 20 Kb/s. downloading KT's kernel using OTA takes about 10 minutes.

I'm not seeing this all the time, in ~20% of the time WiFi to internet is OK.

The most annoying is that my wifes S2 with stock FW and kernel is has a blazing fast wiFi/Internet connection n the same network.

Updating the same app from Google Play on her phone is long finished while mine is still downloading it :crying:

Definitely something strange going on with the wifi. My phone and PC are connected wirelessly to my router. My PC gets 30mb/s and my phone gets about 5mb/s, same server too. I can't work it out, my phone was always getting the same speed as my PC when I used other kernels. It isn't a major problem, the slower speed is still quick enough for browsing and I love the battery life of KT.
[Galaxy S 4 i9505 Original Android Development] Mussels84:
i have the same problem and i'm on 4.4 GE. keep in mind the wifi in these is a lot weaker than on a PC, so interference would grealy affect the phones more than a PC.
[Galaxy S 4 i9505 Original Android Development] kantjer:
I would already be very happy if I could get 5 MB/s internet speed on my phone, I'm getting it on my local LAN, but downloading from the internet it's about 10% of that. My WiFi connected laptop on the same network gets 80 MB/s internet download. :crying: and my wired desktop 160 MB/s
[Galaxy S 4 i9505 Original Android Development] Mussels84:
if we CAN speed up the wifi i'd love to know how - i use ES file explorer to copy files off network shares all the time and get stuck at about 5.5MB/s and would love to be able to speed that up.
[Galaxy S 4 i9505 Original Android Development] !crazy:
I haven't done any test with KT kernel. I'll try to find some time for that later.

With stock CM kernel I am getting 52 Mbit/s on 5 GHz frequency band, and somehow 47 Mbit even if Android report link speed 24 Mbit/sec with 2.4 GHz frequency band.
[Galaxy S 4 i9505 Original Android Development] kantjer:
My results, the upload is what I would expect but the download speed is horrible (150/10 Mb/s connection)

I realy hope somebody finds an answer. My 3G (H+) download speed is much better than WiFi.
[Galaxy S 4 i9505 Original Android Development] Formhault:
I don't think you can get more than that. Although Wireless N can throughput 150 Mbps maximum, you won't be able to harness all that power. Dunno how that works...

I have a D-Link DIR-600 router at home; it can output a maximum of 150 Mbps via Wireless N, but my phone never gets more than ~70 Mbps (maximum I ever got was 6 MB/s, but averages at about 5.5 MB/s). I think you need a hell of a wireless adapter / processor / whatever in order to be able to profit from a full 150 Mbps speed. That, plus a fast internal memory...

Anyway...

It's funny. In the weekend, I got to test my girlfriend's Wi-Fi, with my phone and hers. Her S4 mini got 5 MB/s while my S4 got about 1 MB/s (tested multiple times).

Same router was giving me 5 MB/s a month ago.

But at home, on a very similar router, I get the same ~5 MB/s I always got. :confused:

Am on SlimKat, so AOSP, for what it's worth.

Jfltexx mark is still there for current nightly. Download/changelog site also. But basically nothing should change from kernels point of view.

[Galaxy S 4 i9505 Original Android Development] Solace50:
there's definitely one minor thing thats causing rr's even if they only occur once in a blue moon. on ASOP i still had rr's randomly with kt'z settings minus the undervolting to eliminate stability reasons. ASOP usage was stock cm 4.3 rc builds and i still get the odd RR on tw golden eye na4 based rom. using kt's settings + additional profile settings under extra's. is there some form of continuous logging that can be done to pick up on whats happening before the rr kicks in. im sure it happens the odd time while i sleep as just playing music and nothing else on the way home had the rr happen. i could just play music while sleeping and run some continuous logging to see whats happening.

Yeah aosp is fine. It's the obb folder that's broken in GE. I figured out how to work around it by linking and entire folder called obb with contents using folder mount but since I dual boot this cause major conflicts with my other rom
[Galaxy S 4 i9505 Original Android Development] Shocky2:

With GE you lose Foldermount and in some cases the HDR camera as-well, with AOSP you lose the HDR camera, it's replaced with a fake HDR mode in most cases which looks horrible.

its possibly the file types too. for example. 10 bit H264 (commonly used for anime) will only work in software mode, and with positional subtitles its gunna lag badly.

some files with AC3 audio wont play properly either without a custom codec (MX player has instructions on that one)

MX player is smooth for me except on the really demanding files i mentioned above, so it'd have to be some CPU or GPU setting causing it.

guys am I the only one who doesn't see any advantage in underclocking the CPU? My main usage is tapatalk, whatsapp/fb messeger and browsing so very light tasks. No games whatsoever! If I set the cpu to 1.2Ghz or use only 2 cores the battery stays the same for me with the same screen on time. Is it correct to assume that for lights tasks there's no difference because even if more power is needed the CPU will spent more time working using less energy instead of a fraction of time using more energy.

it doesnt make a huge difference, but for me it keeps my temps down a little.

i downclock to 1.5GHz quad

underclock GPU
