No, its lower. But here can also start some problems. Look it this way: 384mh is a low frequency but can also handle some background load, like networkt activity, music streaming and so on. If you lower it to 192mhz it can still handle music streaming and some activities, but it will scale up sooner then with 384mhz. If you have an intelligent Governor it will only scale up to 384 or one higher. But every calculation and scaling cost you some battery, so in the end you'll maybe save more power, if it stays on 384mhz for example 10mins, then scale between 192mhz and 384mhz in 10mins.

Thankyou for your explanation on this ?

So is it wrong use this as a comparison ?example an engine requires to idle at say 1000rpm lowering the rpm to let's say 800rpm will cause it to stall for each gear the engine has it needs to run at higher rpm or it will stall so trying to

apply this theory here doesn't really work??

It's a nice analogy but gasoline engine work different ?.

There's another factor then just scaling up to a higher freq more frequently, it's called metastability.

Basically it mean that the data at CPU output will be corrupted and the system will crush.

I'm not saying that if you lower the min freq to 81MHz the system will immediately crush but there is the possibility that in some circumstances there will by an error.

yesterday I had the bug where I can't slide from the left or right in an app like g+ anymore. I only experienced this bug with other dt2w but now it also happened here. I disabled and enabled it and it worked again.

sometimes dt2w doesn't work. but it never froze my screen, so still the best implementation :)

If I can help you, I switched like you from N4 to N5 in February and I now use Linaro kernel (based on Franco). It's not Semaphore but a really good one too!

Very trool question..

Sir [MENTION=3750240]stratosk[/MENTION], why in other kernel as hellscore, franco etc antutu have 20000-22000 points and in your kernel "only" 17000-18000???

Battery life is fantastic but at what price?

Thanks;)
[Nexus 4 Original Android Development] Slymobi:
At the price of free ;)

Benchmarks are worthless and have no bearing on day to day usage.

My advise is to delete your benchmark app and just enjoy a smooth ride.

Regards as always
[Nexus 4 Original Android Development] capoooro:
No price at all... Do you believe benchmarks?

This is the smoothest and rocky stable kernel I've tried. Good Easter to everybody

[Nexus 4 Original Android Development] autoradio78:
My question was made on purpose to tease..

I have a lot of experience with Android os and I know that the bench can be skewed..

But when we talk about cpu intenger, float-point etc I have a doubt..

2 way: or 90% of rom and kernel are biased with unnecessary optimizations that turn into cheating, or this kernel and stock kernel-rom not have performance optimizations;)

Happy Easter!
[Nexus 4 Original Android Development] Holer Togni:
For whatever it's worth, IIRC the Antutu score doesn't differ that much between kernels if you're using those optimized dalvik and bionic libs.
[Nexus 4 Original Android Development] stratosk:
Just a shot.

I think that other kernels score much because of modified thermal thresholds.

I don't touch thermal configuration at all.

So, when you start a benchmark app, the CPU is getting hot very easily and the thermal binary caps the max CPU freq to 1.2.

If you raise the thermal thresholds then you can end the benchmark with the highest freq.

Happy Easter everybody!
[Nexus 4 Original Android Development] autoradio78:
Thanks for technical explanation, I wanted this Sir;)

Happy Easter!

Thank you Stratosk, your kernel is a masterpiece.

And by the way I've scored 21000 some months ago with your kernel and motoX_4.4_qcoptimized dalvik's.

Even if it's pointless because I prefer to underclock my cpu to get a good battery life and smothness over big score that does not reflect anything.

I only fear the day you gonna change your phone... ?

You can try undervolting a bit. Also lower the max cpu frequency to something like 1ghz if you don't game on it much. Otherwise try something like 1 or 2 levels below the original max cpu frequency.

Hi Stratosk,

So you're running the latest, okay. Don't know if kernels and radios have such a connection but the wifi connection problem was one of the "features" of .97 radio so that's the reason I asked ... the only one more thing that can I recommend is clean flash of ROM and kernel.

If you have twrp recovery it takes 5 minutes to install ROM+kernel. Once I had a problem with my gps, I've just reinstalled the kernel to solve the problem, then wipe cache and dalvik cache.

Long time lover of semaphore but I have had to cease usage due to acestream (used for xbmc) not being compatible. Maybe a big ask but can [MENTION=3750240]stratosk[/MENTION] / other users maybe test for me or figure out reason why ? I thought the latest version fixed it but after I rebooted it ceased to work again. Ace stream works fine on stock kernel and also slimkat inbuilt kernel. Hate being away from semaphore but xbmc and acestream is a much needed app for me ;).

I'm on holiday and unable to send logs as I'm not using semaphore :( because I need my acestream. The issue is that ace stream on semaphore just crashes. I understand that without logs its hard to pinpoint the cause and hence why I stated it maybe a big ask !

Ace stream apk is also used with torrent stream controller ( installing this will auto install the acestream apk) from playstore . if anyone else can provide needed logs of the crash I would be grateful but if not then I will on my return home get the needed logs to upload.

It works up until a reboot after a semaphore kernel install.

I've been on HellsCore and HellsDoctor for a couple of months, and they were... well, in a word, good.

Yesterday evening I installed SlimKat last stable (build 5) and Semaphore again. I have to say, I can really feel the difference. Mako is faster than ever! Now I'll watch for battery after some cycles, without changing much. I only raised/lowered a couple of parameters of the ondemand governor, as Stratosk suggested, but only a bit, not at all huge changes.

Have a nice day everyone, I'll write back about power consumption.

Do you use uV on Semaphore kernel? Is it safe? Is there any profit on battery juice using it?

What are the parameters for a safe application: Lower uV - Higher uV - Boost Voltages y/n ?
[Nexus 4 Original Android Development] Italico:
Start with -50000 on both high and low, try for some time (days), then try remove the 25000 boost and run again for some days. After that, you can go lower, but do small steps. I think you can go to -100000 without problems, under that level it depends on the SoC you have. Never tick the 'set on boot' option if you have never tested the reduced voltages.

No hardware damages will come from UV abuse, maybe only hard or soft reboot
[Nexus 4 Original Android Development] jimyiak:
i think UV is unique for every phone..when i use UV my phone reboots on camera so i mostly doesn't UV at all!!for example with hells core and hells doctor kernels my phone doesn't boot at all and i think it's because of default UV!try yourself step by step to see when it's stable..my opinion is just disable UV boost and use it like that..there is not so much gain when you undervolt..
[Nexus 4 Original Android Development] Italico:
In fact Hell's kernels are UV yo -100000 by default.

That's why I said to try small steps.

Please that's not the kind of attitude you have around here. Some kernels work for some phones.... Maybe semaphore doesn't work for your phone.
