Yes, try to use your iPhone with 1% battery and it will stutter as if you were using iOS 7 on the iPhone 4! 6s with 10.3.1 here.

That doesn't happen to me, ever. With same 6S. And I'm super sensitive to stutters and sub-60fps refresh :) In fact I don't notice any slowdowns, but they do take place according to benchmarks.

Okay try this:
When your battery level is below 20%, open a video in the YouTube app, and scroll through your subscription feed.
Do you see lag now?

With LPM, I see much more stutter (irregular stutter, not just generally lower fps). Without LPM enabled, scrolling is okay even with <20 % battery.

I did a little test of boot speed on my iPhone 6s with LPM disabled:
On 5% : 35 seconds
On 94%: 20seconds
So I think CPU throttling is happening..
EDIT:
On 100% battery, with LPM ON, the phone booted in "only" 24 seconds. Seems strange to me.
