Which ones do you think make battery worse?

I'm already thinking about changing rq_affinity.
And renicing hd-audio0 has no impact except when audio is playing.

Yeah well those were on my mind, but I also didn't see why you had to modify Wi-Fi power or the way GPU scaling works. They seemed OK as it was, and were designed for a mixture of battery life and performance. The battery life of my Nexus 7 certainly isn't great after a few years, so it's something I keep an eye out for now.

Renice hd-audio0 fixes the irritating audio "frame drops" when multitasking so I think it's worth it.

Re: wifi power: it is only changing MAXIMUM power not default, so only reduces battery at low signal. This made wifi speed in my room (at exact opposite end of house from router) go from 2 to 7mbps.

Same thing for GPU scaling, the kernel code only enables it if GPU has been at 90% load for 10 seconds, which is almost never during non gaming.

Thanks for responding though.

UPDATE;

I posted a new version which reverts rq_affinity to 1 (0 made audio worse)
but makes another VERY SLIGHT eMMC speed compromise to even out the battery effects of rq_affinity

echo 1 > rq_affinity # bouncing around between cores makes audio worse
echo 1 > nomerges # try slightly less hard to merge requests, less cpu load

Gotcha. Sounds reasonable then. I'll give it a go. Thanks for your work and taking the time to explain the technicalities

Just a little suggestion: to allow people to understand which is the actual release, could you please add the date to the title, something like: "ParrotMod_Grouper_Universal2-2016-04-18.zip", "ParrotMod_Grouper_Universal-2016-04-19.zip" etc... and if there is more than a release a day, something like "ParrotMod_Grouper_Universal2-2016-04-18.zip" (initial), ParrotMod_Grouper_Universal2-2016-04-18[2].zip(2nd etc..., otherwise one cannot know what (s)he is using and if it is the latest...
Thanks,

Is this suppose to reboot the tablet on the first boot up like the older version because I'm not seeing no reboot on the latest beta. not unless this has changed where it's not needed. Only thing I was unclear on.

To be fair if you look inside the zip file, all the files have a creation date & time.

A little more clarity on the main page would be a welcome addition regardless. Then I wouldn't have to post minute questions. Like for example my post above weather or not the tablet should reboot like the old version. More clarity goes along ways. But I do appreciate the work done here.

I've just spent the last 10 mins trying to find where, but the OP has said somewhere that the script no longer auto reboots as it is now unnecessary. Forgive me I wasn't trying to be one of those XDA - self appointed - police, I was trying to be helpful.

It is *exactly* what I do every time. Anyway I appreciated the huge effort made by parrotgeek1. Mine was, as I said just a little suggestion.
