Sleeping with partner

I have pretty steady sleep schedule, but even when I start tracking sleep during bedtime, my phone registers me falling asleep after two hours, even though I fall asleep in like 5 minutes. I keep my phone next to my pillow but my man is really active sleeper so I think that affects my sleep ratings (specially because I get better rating after going to bed earlier than him) so I was wondering if anyone has same issue or if there is any advice for better sleep tracking when sharing bed?
