I use them with Android exclusively for regular use. They work great, Pixel 3 here. Occasionally only one connects and I either have to turn Bluetooth on and off again, or put Airpods back and take them out. But only occasionally and usually if the phone is in my back pocket or something.
But the iPhone experience is significantly better. They connect via their special chip so it's more reliable afaik, you get to easily check battery status, and the tip fit test seems to only be available on iPhone. I use my partners iPhone to set it up with the fit test and to occasionally check firmware. But I charge them regularly and have never had a need to check battery life tbh, thorough there is at least one Android app that will check battery life, I didn't think it was that great.
Overall with the Pixel 3 they're still the best noise cancelling and general experience Bluetooth headphones I've ever used.
