not a huge deal, but just wondering if there was a work around?
This could be due to core teo off on screen off. Set a higher max on screen off but leave core two off like that, might be all you need and maybe be abke to keep volts where you like.

I used that program from trepn and it looks like core two turns off automatically as soon as screen goes off and that's with no assistance app.
Burntrat I'm having a similar issue with streaming music just doing but I thought it might of been because of the area I drive through and it just randomly does it, I'm not under volted a lot so I know that's not the issue plus it's happening a different kernel, I upped my min mhz while on Bluetooth but that hasn't seemed to have done it.

Nice research as usual. Ill try these row over stock. Is this for bettery and performance?

I have been using Android Tuner to record activities using different governors to compare the CPU frequencies and load. You can set it to record for an hour at 1 minute intervals and it doesn't consume many resources. I'm determined to find a governor that works well under a fairly large load, so I am using Candy Crush Saga as a benchmark and the results are pretty interesting.
I started recording with my governor set to OnDemand, played the game for a few minutes. Switched to Interactive, then finally conservative. Each time I switched governors I played the game for around 5 minutes, then gave a small break in between to make things easier to see in the graphs.
The first screenshot shows the CPU load and the 2nd shows frequency. You can see that the higher the frequency, the lower the load. OnDemand seems to just peg the CPU at max speed, but keep the 2nd core fairly low. Interactive tends to hang around the "hispeed freq" which I have set to 1134mhz. This can be set lower and I may experiment with this later. Conservative jumps around a bit, but stays low compared to ondemand.
Battery drain seemed fairly steady throughout the testing, but because of the 1 minute sampling time, I think a longer test would be needed to get better data.
The big question that I am trying to answer is which has a bigger impact on battery, high CPU load or high frequency. Sitting at max speed may not be as big of a deal as we think if the loads remain low.
I couldn't agree more. But everything is good in moderation. I think this is true but to a certain extent. I am seeing less battery drain having up thresholds around 60. Seems to keep load down and creat less heat even at higher mhz. But this is not true past a certain point. Set min max 2.1ghz and even idle tasks could lose many percent an hour even with an undervolt. So we need to fond efficient ranges and boost to them early before load gets excessive. But dropping when unneeded efficiently so just the same down threshold must tail right behind and be im close to same range.
