I do know that 9.0 betas are causing some music playback issues during screen-off.

The reason is simple. Your music player somehow requires more than 2 Cortex-A53 cores to be properly played(and it's most likely that it will drain much more battery than a *decent* music player), and 9.0 betas lock down all the rest of the cores during screen-off.

The 9.0-beta5 actually have this behavior user-configurable.

The default value for this will be stayed "on", so users who have issues with music playback and stuffs should disable this feature manually.

I'll post full intructions on how to do this when 9.0 stable goes live.
[Galaxy S6 Edge+ Android Development] citytrader:
Today I made a good test of music with 9b5, I have done 35km with my bicycle today and hearing mp3 with bluetooth all the time, I had very small glitches but this are the normal ones I had with other phones too, I could say that 9b5 is an improvement over the other versions, the battery was really amazing, all time with bluetooth and Jetaudio (I didn't find in the market a player with better quality of audio than this one) I've 5%~6% of battery consumption per hour.

The only issue I noted but I need to do more testing is with Skype and bluetooth, after sometime Skype hanged the call (not the app), this happened with 3G and Wifi, so maybe Skype needs more cores to work.

Arter97, maybe could be a good idea to use Tasker to turn on the cores depending on the applications we are using.

Please flash recovery one more time -----> Done

After do not let the phone restart to system. Restart to recovery first (hold vol up + home button +power button together until you see recovery)

One last question. So is WiFi calling workibg or not. And I believe the answer is no but I just wanted to make sure.

This is my second Sammy device. Had the spri t nite 4 which I got pretty comfortable flashing stuff on it nand I have a bunch of nexus line up including the nexus 6 with custom roms and all that.

Here is the step by step I took in case someone wants a clearer breakdown of the process:

Download Package

Download SuperSU

Copy recovery, superSU zip files to SD Card (dont copy tar.md5)

Enable developer options

Enable OEM mode in developer options

Power device off

Boot to download mode (hold vol down + home + power) and connect device to PC, pres vol up to 'continue' to download mode

In Odin 3.10, click AP and select the tar.md5 recovery file and click start

Once device has booted into System, power it off.

Boot to recovery (hold vol up + home + power)

Flash the recovery zip file.

Select power options, reboot to recovery, no to the "fix root" prompt.

Wipe options, factory reset

Install zip, from sd card, Flash kernel zip file

Install zip, from sd card, Flash SuperSU zip file

Reboot to System

And here I am. Rooted device.

Things to note as a TMo user:

No WiFi Calling.

Unable to disable/enable WiFi calling feature while WiFi is on - just greyed out.

Randomly receive IPSec error when connected to WiFi.

EDIT: Had an issue, realized I flashed the Note 5 kernel on accident. Cleaned up steps.

[Galaxy S6 Edge+ Android Development] superman1979:
Very well said bradahhh :)

We are Guinea pigs for testing. If u dont test, there would be no future improvements.

If ur afraid for alpha and betas. Stay away. Just stick with stable

I salute all the testers for their brave soul :)

And especially Arter, It takes time and effort to program. Without him my s6 edge+ wont be rooted, it would be just a regular phone.

[Galaxy S6 Edge+ Android Development] SetiroN:
I don't understand the elitism behind this reply. So what if some people like to have a music player that automatically downloads lyrics and album art, caches cloud music or does any other kind of additional operations? You seem to imply that those people deserve playback glitches. That's just silly.

In any case, the whole reason for going big.LITTLE is that you can keep lower power cores active without consuming battery. Four active 800MHz A53s consume way less power than two 1500MHz ones. By limiting the number of active cores you're forcing them to run at higher frequencies or causing slowdowns in exchange for extremely limited savings. It made sense when we only had high power cores (SD <805), but in this case I don't think it does.

I'm glad you're adding a sysfs tunable for that option but I think the default setting should be to leave all A53s active while disabling the A57s when the screen is off.
[Galaxy S6 Edge+ Android Development] arter97:
I apologize if my post sounded offensive. I definitely did not meant that crappy music player listeners should get crappy playback. What I meant by decent music player is one with a good quality audio decoder that does not relies on CPU that much, and those are the ones that most users will have.

I don't know if you got a chance to look at Samsung's default hotplugging driver. It turns on all CPU cores, including A57 ones during screen-off if QoS gets called(which is quite frequent, unfortunately) or there is a slight usage bump. This is very inefficient and inspired me to improve it. So I had to write a bit of code myself to limit the number of cores that are allowed to be turned on during screen-off. I went with 2 because 2 A53 cores outperforms most single A9 and A15, and most A9 and A15 devices limit themselves to leave just the cpu0 during screen-off.

And I had a bit of testings myself to ensure 2 A53 cores are enough by using ViPER EQ(which eats CPU), Bluetooth audio streaming(which also eats CPU) with APT-x disabled(so that's AAC) and SW audio decoder(which would be the biggest CPU consumer). I did not encounter any music playback issues so I went with it and I'm sure most users would be fine with 2 A53 cores.

And FYI, fewer cores running at higher freqs is much more power efficient than many cores running at lower freqs.
[Galaxy S6 Edge+ Android Development] qsy124:
i feel like 2 a53 are already too much for musicplayer, if2 a53 cant handle it, how come some old device which only have 2 core to play music through that player....

Why people write its SOT is something I don't understand... is totally useless
[Galaxy S6 Edge+ Android Development] xanthrax:
Ok, can you tell us then which is the useful measurement standard?

You obviously miss something here pal, you don't realise that one claims the sot based on his usage but when that individual returns a result, better or worse, it's based on approximately same usage so, that's extremely useful for him to figure out whether the kernel or ROM fits his needs

I realy hope that you won't expect, for the sake of the accuracy, that every sot posted must be accompanied by all personal usage details, there are way too many variables but please, let people post their sot that someone can have a small idea about how this kernel can bring something better for the users

Not everyone it's that experienced to perform a deep analysis on a kernel so, the sot may be generally the first point of reference

Sent from my Darkside of the Edge+
[Galaxy S6 Edge+ Android Development] citytrader:
There is not useful measurement standard, each one uses the phone in diferent way, if someone post a SOT of 15hs I will say: "I don't care", my SOT is 3hs and if other user is using the phone exactly like me, it will get SOT of 3hrs, at this point SOT is totally useless. If I change the Kernel and if the kernel drains to much battery I will see the difference, but if the change is minimal, I won't see anything.

So at this point if someone post a SOT of 25hrs, 10hrs, 5hrs,etc on the other side will be someone that will say: "who cares!"... :D
[Galaxy S6 Edge+ Android Development] arter97:
I appreciate SOT feedbacks.

Yes, it's not meaningful when someone posts 3 hrs of SOT and complains bohoohoo or 10 hrs of SOT on airplane mode.

But I still need some average among different users. If average got all the way down to 2~3 hrs, it's most likely that my kernel's screwed.
[Galaxy S6 Edge+ Android Development] citytrader:
I think that putting the consumption of %battery / hour is much more useful than SOT, because SOT is very subjetive...
[Galaxy S6 Edge+ Android Development] Ha3ks:
This is my battery with 8.1 over 12 hours use
[Galaxy S6 Edge+ Android Development] selferng:
I beg to differ bro. I m using my phone in a standard method through out my days. Some gaming, some videos and web browsing with h+ internet. Without root and kernel , my sot is always around 4 hours before it completely dead. With artel kernel it hit 5 hours of sot. Which is a huge improvement by almost 20%. :D
[Galaxy S6 Edge+ Android Development] arter97:
Those who're wondering, most of my kernels are backwards compatible with older releases.

You're completely fine to switch all the way from 3.6 kernel to latest alpha/beta releases.

If you don't like latest development of this kernel, I'd appreciate some feedbacks and logs but also, you're completely free to choose to go with older kernel.
[Galaxy S6 Edge+ Android Development] xanthrax:
This is my simplest way to observe the kernel behaviour

On the pic below there is this app called cool tools

I've added this basis parameters: cpu freq, cpu temp, battery temp and cpu voltage

Based on what I do with the phone those parameters tells me how the kernel behaves

The voltage when using Tapatalk for example is 106 now when I'm writing which is awesome comparing to more than 200 on other kernels, the speed stays 400 almost all the time and so on

If I notice anything abnormal, I go to other tools to check, better battery stats or Wakelock detector or system info monitor and I try to draw a conclusion

At the end of the battery I check the sot, I revise my usage, what I've done with my phone and conclude

The sot along with some other small details speaks about the kernel, isn't totally useless

Measuring the % per hour is the same as the sot if isn't accompanied by some other small details

Of course, feedback on how certain apps behaves on certain conditions may be important as well, the music player for example

Good job arter mate, keep it up!

[Galaxy S6 Edge+ Android Development] xanthrax:
Not really, the speed spikes are quite fast according to what is happening in the system but an average voltage usage it's useful, for me at least, showing the battery consumption at some points

Of course the voltage it's directly proportional to the speed but certain kernel tweaks may deal different with it
