Lets get testing guys, post your findings below
for anyone having problems downloading in your region, find file in attachment below.

Thanks, I will try in one moment xP

Do you know if it modifies kernel or interferes with setCPU?
I sent them a message about it, let's see what they say.

No it don't mess with kernel, I also don't think it adjust cpu frequency as I think it would need root permission, which this app don't require.

yepp, I installed it, and looks like what it does is that it organises when apps connect for sync and update, which sounds really good, and others don't do that.

yep, they said:
Thank you for your enquiry.
BatteryGuru does not modify the kernel or CPU settings in and way.

[Q] Important CPU governor question to those with rooted HTC One

Guys with a rooted HTC One, please confirm what CPU governors are supplied by default on the device also what IO schedulers
ie: ondemand, interactive etc...
there should be an MSM-DCVS governor which would bring the most performance out of the device
please confirm
you can find out by apps like SetCPU, trickster mod and system tuner

Stock = ondemand-cfq

****ing awesome
and correction deagleone, it seems to be using noop instead of CFQ (which is vastly better)

yes it doesn't mean much
GL benchmark already demands full performance regardless of the governor, unlike 99% of games which require CPU governor change to prevent fps stalls usually caused by ondemand governor
but i was still kinda hoping...
anyway many thanks mate, very helpful :good:
more info here

Seems like the fps is locked down on 34fps on kernel level. If this was the maximum the gpu could provide it should fluctuate to lower or sometimes higher score instead of giving a consistent 34fps score.

Screen color temperature

Is there a mod or a kernel to flash that allows to change the color screen temperature? Mine is a little too warm and i'd like to became more cold.

With CyanogenMod 10.1.2 I could change the colour temperature, but with 10.2 I just can't find that setting anymore. Was it removed and is there a way?
If not, that app is good? I read Chainfire3D, but it's for older android versions.

Faux kernel, if you mean this

Is there a smaller and more specific app? Faux kernel does a load of things, which explains the price, not worth buying if all you need is to make your screen slightly colder in temperature.
Can't believe it is so hard to find this. Like I could not believe nobody ever seemed to have made a Galaxy S3 analogue clock widget.

I don't know mate.
Fauxclock is built for faux kernel in advance, but probably is compatible with a lot of kernel.
However, try to search on the play store or here on xda.
p.s. The kernel have to support this feature too

Latest ElementalX-Versions support changing colors, best is to read the last pages as some spotted this topic. Faux's Kernel Tuner was the only mentioned app though for changing the colours AFAIR..

8.4 do not have hmp

just wonder about that.
some say exynos 5420 support hmp by theory, yet samsung disable it, while 5422 / 5430 / 5433 support in reality.
i check it by cpuz, it clearly shows cluster switch and only 4 cores can be use at the same time.
5433 (note 4)

5430 (samsung alpha)
5422 (ODROID-XU3 Lite System)
5420 (note3)
even note3 get lollipop update, kernel is still a 3.49, no hmp will be given, it shows only linux about 3.10 can support hmp.
and i don't think samsung will update kernel for us.

Heat and battery-life wise I do not reckon they would enable this.

What is hmp?

Ah this conversation again. The exynos5420 was supposed to support hmp but ended up being broken and as such will never work. Sorry guys.

Yep. According to AndreiLux it is impossible to be implemented for our Exynos5420. He has stated the exact reasons why in various posts on the Web.
I have seen evidence of working HMP on Samsung Exynos5420 at one of the developer shows a year or so back though, but doesn't necessarily mean a software patch will make it work here. Hardware needs work too, which we can't change. ...

CPU-z
i just noticed something else wrong with my galaxy tab s 8.4 the CPU-Z info "http://i.cubeupload.com/3LpKj0.png" the exynos 5420 suppose to be with 4 slow cores at 1.5 and 4 fast cores at 1.9 but on this info from CPU-z it shows them all as 1.9 somehow , and also here "http://i.cubeupload.com/vUgZnP.png" it shows the screen dpi 320 instead of 359 . is it the same on your device as well ? can you share any screenshots or info thanks im using CPU-z 1.1 btw

Either the app is wrong or you have the later model with Exynos 5433.

Undervolting and Kernel Settings Discussion

I've been wondering about what to expect when undervolting. There's only one kernel for this phone that I know of, the Render one; if there are more, feel free to point them out. Additionally, what kind of global offsets can I expect, and what are your settings?

Does anybody tried undervolting yet ? Is it worth to play around with lower values and save some juice or not ?

i've tryed to set lower voltage setting via kernel auditor on custom Krait kernel but, as i think, had random reboots while CPU loading growed up in short time...
Still testing on new kernel build

No undervolting but try interative governor tweaks. There is a guide how to in Nexus 5X general.
