No, it depends by the ROM too.

You're welcome.
The default configuration (Interactive + Zen) is good.

OK it's only been a few hours but battery already looks better with this kernel. I'm using lionfish + fiops. Good stuff.

Since flashing this kernel, I have no call function. Keeps ending milliseconds after calling.
Any suggestions?

EDIT: fine now. Had to adjust APN settings

So while the kernel seems to boost battery life with the right governor, it also seems to cause the phone to freeze up randomly and eventually reboot, at least with the 10/09 build of the AOSP Nougat ROM. It happened a few times after the screen had gone to sleep and it just wouldn't come on again. I only tried 2 governors - lionfish and bluactive - so I have no idea whether it's the governors or the kernel.

It works fine for me with latest AOSP 7 build. Try with Interactive.

Good to know, thanks for report.

Kernel looks great, no issues yet. With standard settings. ^^ Hope for updates in the future

The phones does go to hard sleep if governor is lionfish. Interactive seems fine.

Well the whole point - for me - of installing the kernel was to try goverors other than interactive That said, I did give Interactive a try, and I got a reboot. But I was suspecting the problem might be the Instagram app, which I installed right after flashing the kernel the first time. Sure enough, removing Instagram has gotten rid of the problems with all the governors I have tried - no more reboots or freeze-ups.
To be honest Instagram might even cause problems with AOSP 7 even without this kernel, I have to admit I haven't tested that (though I don't think so). In any case, beware the Instagram app...

It's definitely a Lionfish related problem. Thanks for report.

You may have something else going on in your phone. I am using it on 7.0 and it works perfectly.

Yes, and someone reported problem with the Blu active governor as well.

I spoke too soon. Another reboot with Interactive, but without Instagram - so it's not that. Suspect it's Greenify actually, I had it in Shallow Hibernation (forgot, thought I had turned it off). Would be consistent with the issues I had with bluactive and lionfish, and the issues reported above.

What value do I set for notification light? I can see for charging, etc but no notification.
