No. There is no tutorial because this is a development thread. As stated in Post #3, all devices aren't created equal. Generally, you need to tune any voltage or frequency to suit your own specific device.

All that can be suggested is:

1. Don't UV too much at a time. Start at -25 mV

2. Don't UV all frequency whilst testing. You can then narrow down any particular frequency causing reboot.

3. Don't UV all CPU and GPU etc whilst testing. You can narrow down cause of reboot.

4. Ensure Synapse app settings ARE NOT APPLIED ON BOOT whilst testing. May cause issue during boot trying to apply unstable settings.

5. WARNING: Random reboot may cause for corruption and or data loss. Maybe disable Dynamic FSync whilst testing. No guarantee though.

6. Once you've found stable frequency sets, increase all voltage + 6.25 mV for reliability

7. Underclocking frequency may cause instability too

I haven't noticed anything on my N920C. Make sure USB debugging is enabled in device developer settings. Also try without Synapse

I think I used the wrong words saying guide. I meant tips lol...the way you just explained it. Thank you sir. And much props to you for understanding all what you work in. It is amazing to understand and develop kernels...to me, quite difficult. Blessings and best of wishes. Thank You. I was on Arter...and this kernel flies. I followed your battery saving tips in the 1st page. ..already seen SIGNIFICANT BATTERY SAVINGS.

Just flashed 3.9, anyone want to help me out with a profile. I have looked through most of the thread and haven't found much so any help would be appreciated.
[T-Mobile Samsung Galaxy Note5] muffinsmuffy:
Had your issue once on note 4 turned out to be usb port had liquid damage im suspect you might have the same try flashing stock first and see if it does the same thing you might have a damaged usb port and you need to take in for sammy to swap it out

---------- Post added at 04:09 AM ---------- Previous post was at 04:04 AM ----------

Make you own profile to suit your needs mate thats why they are "CUSTOM" kernels if you use our profiles you might have trouble

I wish I knew why Kernel 3.0 is the only one that works well with my GEAR VR.
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
You must have "missed" Post #3 and my previous post !! A good place to start ;)
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Ahhh

This IS NOT working as hoped...

Once the screen goes off, it works once and that's it. A lot of time into another failure, but anyway still many success up to v3.9 :)

Time to remove it and look at something else. Maybe i'll add the CortexBrain later on with some other screen on off functions
[T-Mobile Samsung Galaxy Note5] Rx8Driver:
What does this service adjust between screen states?

Edit- nevermind, i see...
[T-Mobile Samsung Galaxy Note5] lightninbug:
Awesome kernel man!!!! Screw the haters! This kernel MAKES this phone!! All settings are stock. Nothing has been done except flashing the kernel and following directions in OP.. Look at my screenshots!! http://imgur.com/a/2C9AP

Gotta admit he knows his stuff been using his kernel for a while now and i caaaaaaanot believe how good this is
[T-Mobile Samsung Galaxy Note5] NickMidd91:
Hey the kernel skyhigh v3.9 was the reason for me having signal issues and I switched to arteries v11 and know have no problem.
[T-Mobile Samsung Galaxy Note5] muffinsmuffy:
Thought the modem handled signal
[T-Mobile Samsung Galaxy Note5] NickMidd91:
The the kernel does

---------- Post added at 03:54 PM ---------- Previous post was at 03:52 PM ----------

I'm getting full signal with arter97 and I was going from 5 bars to 2 or 1 with skyhigh kernel v3.9 don't get me wrong that kernel is good but I'm not going to use it till I know that problem is fixed.
[T-Mobile Samsung Galaxy Note5] guaneet:
Only true way to gauge your signal is to look at settings>about phone>status> sim and look at signal strength

And make sure they are in the same exact spot when you test the signal with each kernel
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
And also same network type for test.

Mostly down to mostly the modem, but also ROM RIL, and the modem driver.
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Last night had extreme battery drain caused by wlan_wake. ~40% in ~5 hours.

The only difference (to kernel) made was setting the Synapse wifi wakelock control to 4. When waking the phone, I noticed the wifi was not connected but still trying to connect all that time. I've set the control to 2 and will test. I've never had that issue before, except for the additional 2x SIP VOIP accounts connected might be a factor (but weren't the night before).

I think that the values I've set are too high, making for (for wifi and GPS) controls not long enough wakelock time.

So I might change some (control) limits for future releases (whenever that is).
[T-Mobile Samsung Galaxy Note5] CanMan1:
I don't think it's necessary to limit the wake lock values. I've been setting bcr (GPS) and wlan wake lock controls at both 4 and 6 with improved sleep time and battery life as a result.

If you haven't already, I think you should be looking at other sources of wake locks rather than just the kernel when diagnosing the issue.
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
No. They will be limited. Setting wifi to 4 is too aggressive. Thats why it would not keep active.
[T-Mobile Samsung Galaxy Note5] muffinsmuffy:
+1 battery hogs suck
[T-Mobile Samsung Galaxy Note5] CanMan1:
Is it the same situation with GPS?

I find it strange that nobody else who's changed these values has mentioned battery drain as a result.

This problem doesn't exists unless you've changed this wake lock value.
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Setting wifi wakelock value too high was an indirect cause of the drain. Preventing the wifi becoming active was the result and hence no deep sleep.

I couldn't imagine the GPS being affected unless it is actually active (in use) such as in maps with appropriate location settings.

I'm going to reduce the max allowable for GPS to 4 and wifi to maybe 2 or 3.
[T-Mobile Samsung Galaxy Note5] CanMan1:
Even though I don't have GPS enabled, I still get bcm4773 wake locks, and increasing the value seems to reduce bcm4773 wake time. Any idea why?
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
I don't know. Perhaps some app or ROM feature. You could look through logcat if you're that interested.

Anyway. My overnight WiFi idle battery drain sorted after some adjustments. WiFi wakelock set at 3 max. ~4-5% in ~7+ hours with WiFi on, GPS on, 3 Google accounts, 1x exchange, 2x SIP VOIP (1000+ wakeups) and more. .. So happy enough. . .
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
As you can tell, this is just at an early stage of implementation. I'll be adding xbox module as well and descriptions etc.

I will at some point discontinue Odin support and have these modules flashed/installed from zip (instead of in-built). I can then shrink the boot.img to hopefully allow a better compression/decompression algorithm. The faster ones increase boot.img size, so need to make room.
[T-Mobile Samsung Galaxy Note5] CanMan1:
Can you make IPv6 a loadable module?
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Maybe possible. I don't know if it would compile and load. In any case, doing so, would screw up the IPv6 controls in Synapse. If that's the case, not going to happen. I might give a brief test at some future point, but no promises.
[T-Mobile Samsung Galaxy Note5] tazzysingh1731:
So finally got the best settings suitable for deep sleep . Here are the changes I've made to get this out of sky-high 3.9(WiFi on )

Power suspend =users pace enabled

WIFI DTIM interval while screen off =10

WLAN_CTRL =4

Rest all is stock

Deep sleep improved from 84 to 98%

P/H usage was 0.8-0.9 and now 0.2 -0.3

Huge huge improvement

Cheers
[T-Mobile Samsung Galaxy Note5] LiL_Assassin:
Nice mate. If you ever manage to get it lower than 0.3% let me know. I got mine down to 0.3% but no lower.

Because you aren't probably doing it right and reading / following the instructions.

Backup:

1. Enter profile name and apply in Synapse

2. Press the backup profile button

3. Press restart Synapse button down bottom to refresh list

Restore:

1. Select profile mane and apply in Synapse

2. Press restore selected profile

3. Press restart Synapse button down bottom to refresh list

4. When Synapse restarts, press the X button !!
[T-Mobile Samsung Galaxy Note5] sshafranko:
Mine works. I named my current set up Battery and Synapse saved it as Battery.txt...
[T-Mobile Samsung Galaxy Note5] danon.brown:
How are you saving it? I don't have the check at the top to apply it.
[T-Mobile Samsung Galaxy Note5] sshafranko:
When i named it the check appeared...let me look again hold on
[T-Mobile Samsung Galaxy Note5] sshafranko:
I named the back up then hit done on my keyboard and yhe check appears. If it doesnt wotk for you i would try wiping data in synapse. I wiped data in synapse before i flashed the kernel. If your coming from another kernel and you are using Synapse with it, if you dont wipe data before you flash skyhigh a lot of issues will be present.
[T-Mobile Samsung Galaxy Note5] danon.brown:
It appears after you hit done on the keyboard. Thanks!
[T-Mobile Samsung Galaxy Note5] sshafranko:
Awesome glad you got it danon....Heres my battery stats for the first full charge cycle. Very happy with this kernel so far. So now only thing i have left to test is the loss of audio after 8min or so on a call with Volte on, which i experienced on the previous kernel i used not this one yet....Up i really hope your not leaving us and you continue to support 920T...Thanks
[T-Mobile Samsung Galaxy Note5] danon.brown:
Maybe you could attach the saved profile text file. I could use that as a base to tweak or leave it as is. Its in the skyhigh folder.

If you randomly reboot or your screen freezes with my profile, raise the voltage a notch or two.
[T-Mobile Samsung Galaxy Note5] Monsi:
I'm reading great things about this kernel... Jumping ship to here. Great so far.
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Please ensure user posts the asv_summary along with any profiles.

There are no specific "defaults" for CPU or GPU voltages. It depends on your "build quality" as defined by your asv_group / asv_summary. So not all are created equal. Users need to post the their asv_summary when considering voltage adjustments etc.

Read the INFO section in Synapse about asv and Google the rest of you need more info ;)
[T-Mobile Samsung Galaxy Note5] dandroid7:
Been running this kernel for about 36 hours so far... it is running very stable and smooth.

No random reboots!!

[T-Mobile Samsung Galaxy Note5] sshafranko:
My input is at 1000 and my charge is at 1500...honestly not gonna make much of a difference because the charger itself is limited. You need the fast charge wireless charger for what your looking for i think.

---------- Post added at 02:33 PM ---------- Previous post was at 02:30 PM ----------

You might have a rogue app..check it out with wakelock detector or such. I had arters kernel, wiped data in synapse, booted to recovery wioed caches, flashed sky, wioed caches again and booted. Left alone for 5 min. Then i let kernel set in for a couple hrs and then applied my settings. Been great for me so far.
[T-Mobile Samsung Galaxy Note5] drbveb88:
I want this!! How do I install your profile above? I am a noob to Synapse. Lol

Thanks!!
[T-Mobile Samsung Galaxy Note5] sshafranko:
Can you post a screen shot of your avs table first please? Its in the info page of synapse. Depending on your Avs ill create and upload another profile for you if mine is too steep.

That is with aeroplane mode on though. Turn data on and tell me if you get the same thing. But nice either way
[T-Mobile Samsung Galaxy Note5] tazzysingh1731:
Lol the only thing was draining battery in idle mode with skyhigh was wifi wakelock I don't I got it right from 80% deep sleep to 98% that's all I wanted

Cheers
[T-Mobile Samsung Galaxy Note5] LiL_Assassin:
I dont get this wifi wakelock. Ive heard a few people get it even on stock mode, but its still a good result. I was just hoping to see if anyone could get it lower than 0.3% with wifi and data on. But i dont think its possible. .maybe with marshmallow
[T-Mobile Samsung Galaxy Note5] NotATreoFan:
I was (and still am) running a test version of 4.0, and the WLAN wakelock is definitely better than I had before. Still sitting around 3%, but I'm OK with that since I was waking up to 5-7%/hr loss just while sleeping before. If I went to sleep with WiFi off, then my drain was close to 1%/hr sitting on T-Mobile LTE.

I've also narrowed one of the battery drain causes to the Note 5 RAM fix nearly everyone has done in order to stop their apps from getting killed as soon as they idle for 10 minutes.

But based on the last 4 days testing various ROMs and configurations, I have no doubt the WLAN battery drain is not exclusive to SkyHigh, and there are several other factors in play.
[T-Mobile Samsung Galaxy Note5] muffinsmuffy:
Whats your sot
[T-Mobile Samsung Galaxy Note5] NotATreoFan:
My average SOT tends to be around 3 hours before I plug in and recharge to start the next test. But my battery will still be around 40-50% with that time.
[T-Mobile Samsung Galaxy Note5] muffinsmuffy:
Not too bad mate
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Thanks again for your time to test mate.

I've just changed some default wakelock timeouts at source level which I feel will help/beneficial. Nothing "new" as such, but user won't "have" to set in Synapse (although control is still optional to adjust to stock or other value).

Just woke up with ~0.5%/hr drain over 6 hours on my stock N920C. Wifi on + 3x Gmail sync, 1x exchange sync, 2x SIP VOIP registered (1000+ wakeups), GPS location on, and more. Network signal strength is poor -107dBm with LTE. All Cron tasks are enabled.
[T-Mobile Samsung Galaxy Note5] tazzysingh1731:
Thanks for the update and making it easier for those who aren't familiar with tweaking synapse settings and definitely improved deep sleep

I've a small request if you could add that in next update . I definitely get better deep sleep less wakelock time when I set wifi wakelock at 4 but on 4.0 the max is 3 so if you could make it to 4 as optional that'd be great again different settings for different device

Thanks mate keep it up the good work
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
3 is the limit I'm comfortable with and set for reasons as previously stated. Saves user induced issues coming back to bight.
[T-Mobile Samsung Galaxy Note5] Lifeis4real:
Awesome kernel hands down the best for note 5.

Would it be possible to add Zen for the i/o scheduler for the next update? I heard it would go nice for gaming xD.

Thanks Again
[T-Mobile Samsung Galaxy Note5] NotATreoFan:
You're welcome, and thanks for letting me test them.

I'm looking forward to any changes you can make to WiFi, so that I can leave it on overnight. I do have unlimited data, so no worries there, but my 150/150 fiber internet does help stream just a bit better than LTE.

[MENTION=3511708]UpInTheAir[/MENTION]

I made a few changes inside Synapse last night, and my idle drain dropped to an average of 0.9%/hr from 11PM until 5AM when my alarm went off.

WiFi Power Mode (Screen On): Set to Off, instead of Fast

WiFi Power Mode (Screen Off): Set to Fast, instead of Max

Wireless Wakelock Timeout Control: Set to 2, instead of 1

Chrontab Enabled

Google Service Restart Enabled

Turned the screen off/on to set the WiFi state, then rebooted the phone and charged back up to 100%. Battery was at 96% when I woke up.
[T-Mobile Samsung Galaxy Note5] jdidtht:
Max brightness on 4.0 seems to have been decreased, it's set to max at 255 but it seems to be decreased overall across the board . Same rom and all that
[T-Mobile Samsung Galaxy Note5] Лithium-Фusion:
If you're on Tekxodus, try outdoor mode in display settings. Its 255 while outdoor mode is on(v3.9).
[T-Mobile Samsung Galaxy Note5] jdidtht:
I'm on 6.0 tech, and between 3.9 and 4.0 100% seems like 60%. All display settings are default. Max of 255 on 4.0, 3.9 I flash and it's just seems overall brighter for me
[T-Mobile Samsung Galaxy Note5] Jhfreeze:
It's his (tek's) services.jar, I figured that out a while back because I couldn't stand it. I actually modified it to stop the mandatory auto bright and just manually push it there each update. If you put the sensor under a light it'll go full bright but I like mine to stay where I put it.
[T-Mobile Samsung Galaxy Note5] jdidtht:
Okay, well on the rom, I literally can flash 3.9, have normal brightness, flash 4.0 and have it cut by 30 or 40%, flash back to 3.9 and it's fine. So, I'll stay on 3.9 since it works normally
[T-Mobile Samsung Galaxy Note5] Jhfreeze:
Weird, no matter what kernel I was on until I modified that framework file my brightness was cut by 40%, only reason I brought It up. If you want at some point to test it yourself let me know.
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
Thanks for sharing. Changing that screen off power mode should increase consumption. Some things might just be to do with router protocols etc. Just guessing. Let's hope your success isn't just a one off

Nothing is changed. If using auto brightness, you should always toggle it off > on after any kernel flash
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
The A-Team "I love it when a plan comes together" Ha-Ha

A couple bugs though. ..

I need to "Noob proof" it a little / somehow. Things will come back to bight, even if it's "beta"

[T-Mobile Samsung Galaxy Note5] NotATreoFan:
Here is a screenshot of my time spent in the office today. Connected to WLAN, but no WiFi Calling so LTE was also active throughout the day. I purposely limited my use in order to get a good idea of idle drain since this is the worst place I spend time, from a coverage perspective.
[T-Mobile Samsung Galaxy Note5] steve97ta:
Nice! Can't wait!
[T-Mobile Samsung Galaxy Note5] UpInTheAir:
The post you quoted has nothing to do with the KT auto hotplug governor. He had only used the core control function in MULTICORE to disable. They won't HP back on, but KT governor will. Also, have tunables to set many things, including individual core up/down thresholds to turn on or off each core. You can disable HP for either/both A57 & A53 domain. As I said heaps of options.
[T-Mobile Samsung Galaxy Note5] muffinsmuffy:

[T-Mobile Samsung Galaxy Note5] UpInTheAir:
I might push out a BETA release :)

Managed to fix the previous attempts where cpu frequency would not change. Thats the clincher!

Some boost don't work as I've not complied with Input Booster enabled. Tried that and was laggy as hell. Also the Synapse layout will change a little to accommodate the KT hotplug governor. Single gov control to set A57 & A53 at same time, otherwise reboot. .

Users can play with the hotplug tuning and hopefully have some feedback for better generic values for me whilst I tinker here and there. ...well, at least try ;)
