[size=+2]Introduction[/size]
This kernel is based on Lineage OS's kernel source code for OnePlus 2, the main aim of this kernel is to provide Good battery life,
and to do so I have added bunch of stuff and tweaked code to improve battery and also to make sure that you don't get lag and delay I have improved the performance enough, and you can be the boss of your own device(Check Features you'll understand).

[size=+2]Features[/size]

[size=+1]Compactibility[/size]

RC / Beta 2.x Works with all Nougat ROMs

Bluebolt Kernel Tweaking App - One Dot One HotFix​

[/size]

Beta : They are compiled with new commits and some bugs might be there. If the things work the way they are supposed to be, those commits will make to the RC
RC : Release Candidate, it is supposed to be stable

Flashing and tweaking

• Installation / Flashing - Download the zip, beta or RC which ever you want to, now boot into recovery and flash from there and then boot into system Voila the kernel is flashed
• (Optional) - Clear cache and Dalvik
• To tweak use Kernel Adiutor Mod or EXKM.
• Spectrum - I've made 4 predefined settings in kernel (Battery, Balanced, Performance, Gaming) which can be switched through this app as per your need, default is balanced. Download Link is in the change-log post.

BlueBolt Kernel Tweaking App (Requires Root)
This app is made to give users feature which they want to control but are not supported by other Kernel tweaking app, this app might not work as intended on other kernels.
The app is in its initial stage, So, if there's a issue report it so that I can work on it, also in case any crashes or issue provide logs also if possible steps to reproduce it.
V OneDotOneHotFix (Oreo):
- Fixed App FC when pocket mode was activated.


V OneDotOne (Oreo):
- Pocket mode Notification won't stay on top and neither will it show up in status bar.
- Pocket Mode quick tile has been added for more convince.

V OneDotZero (Oreo) :
- Added Apply on Boot option. (Only I have tested it so far, and it worked fine. If you find any issues provide me steps to reproduce it.)
- UI / UX improvements.
- Performance improvements.

v 1.3.Beta : (Oreo)
- UI Fixes and Improvements for screen with lower DPI.
- Backlight control are reworked.
- Give user an appropriate message in case device is not rooted.


v 1.2.Beta : (Oreo)
- Added true Splash screen till the time app doesn't loads fully.

- Fixed issue with PocketMode not applying right away.
- Fixed issue with app using unnecessary SU permissions all the time.

 

[chxei]

is it undervolted? little bit undervolting on lowest frequency can improve battery life ?

 

[ShreyanshLodha]

is it undervolted? little bit undervolting on lowest frequency can improve battery life ?

It is in a way.
As its min frequency is 302MHz and it is volted at 780mAh
Before it was 384MHz at 855mAh

you can undervolt yourself by changing it in KA app
KA -> CPU Voltage
change it for the frequency you want
Beware that. After changing the default rates in CPU voltage I wont be responsible.

 

[PeterImmel]

If I use it with dirty unicorns can I enable dt2w in kernel adiutor?

 

[chxei]

@ShreyanshLodha music stops playing if i turn off screen. using latest rc build and blackplayer

 

[ShreyanshLodha]

No it'll breaks, This is the issue with every Lineage OS Based kernel.

 

[ShreyanshLodha]

I'll check and revert back to you!
meanwhile just add the music player in whitelist of battery optimisation.

There's no possibility to make it work?

 

[ShreyanshLodha]

At the moment no, Request the dev to add the commit that I have mentioned in OP.
Which will make atleast DT2W work.

now it plays but it slutters and is very laggy

---------- Post added at 13:50 ---------- Previous post was at 13:47 ----------

tryed different hotpluges, governors and schedulers but with no luck

Its probably a bug of pdesireAudio I'll check if I can fix it
Or I'll revert back to just Faux audio...

If you want You can flash RC 1.1 It doesnt have pdesireaudio.

 

[ShreyanshLodha]

@chxei just tell me what music players have you used and are you using any audio mods or not and also tell me if you were playing music online or music was stored on device.

music player: blackplayer
music mods: none
music stored localy

I'd suggest you use phonograph or play music, and test it with them, none of my testers have reported this issue!!
I am personally using phonograph and the playback it smooth and clear!


And if you get equalizer or some music mod app that comes with your ROM like in DU, RR and AEX then also put them in whitelist for battery optimisation.

Had the similar issue n now it solved!! i'm on Unofficial RR+Viper4Arise+Play Music. Songs play just fine:good:
Also charging speed increased far better than stock kernel.:highfive:

Minor thing is, i feel bit laggy while using Google now, FB & Insta. Is there anyway to speed it up a little?? what governor do you suggest?? let me know buddy?!!

Thanks @ShreyanshLodha for such an effort maann! appreciate it very much.

If you feel that there's lag then,
make sure you are using any one hotplug (dont disable it and you cant use multiple)
And also you can increase min freq of the big core to 38X MHz
There are many ways, I'd suggest that you google it or read this thread.
And adjust make adjustments accordingly.

This kernel is los based !They only way for it to work is the kernel to be based on aosp so those gestures will not work on any aosp-caf roms!

There's no possibility to make it work?

Reported. This is not original development. This thread belongs to the android development section
It looks like a bunch of stuff pulled in from my repos and also from darkbeast kernel
