does this do open tuning?

Not specifically, it reads out the note that is being played. You can tune the strings to whatever notes you like as it is a chromatic tuner, but it does not have specific settings for open tunings.

What is detection accuracy in polyphonic mode?

I don't know for sure but since the other answer described the display of the notes, I'm going to guess that the polyphonic mode (though dependent on your instrument) probably reads 'in tune' when the pitches are within 1-2 cents of the assumed pitches. I too would like to know Polytune's official answer to your question. I'm assuming their .02 cents refers to a totally pure, fundamental heavy articulation of the note being measured. Plucking technique and observer bias can cause all sorts of different observations (accuracy/inaccuracy) but intonation of Em7sus4 chords are definitely averages of harmonic content, I'm not sure it's possible to decide on a specific frequency (at a resolution of .02 cents) when the instrument is moving sympathetically to other pitches. The Polyphonic feature is really for when you don't have time to tune it note by note but you need to have the confidence that you'll be close enough not to come across as deaf to your own sound.

Is the auto off defeatable? A few minutes is unacceptable. I need it to stay on.

I’m not sure what you’re using it for, but if your stringed instrument won’t stay in tune for more than a few minutes, you might need a more robust instrument. And it should stay on as long as it’s recognizing the tuning activity. I’ve never had one power off while I’m tuning up. Play hard, rock on.
