I've noticed that mine drops when I have more than one set of Bluetooth earbuds nearby.  See if that's your problem.  I'm not a massive fan of AirPods, but they're good enough for working out, which is what I primarily use them for.  I also like that they charge quickly.

I bet this will be an unpopular opinion, but I've tried for years to get on the bandwagon, since AirPods are supposed to pair nicely with my iPhone.  However, they constantly get disconnected and have to be paired again, their noise cancellation abilities are laughable, and they're uncomfortable to wear.  The worst bit is that audio tones sound muddled rather than crisp.  Music has no warmth or nuance.  I think it's time to admit that these don't work and to find a different set of wireless earbuds.  Hopefully there's something better out there.
