Moto dual-sim phones are active dual-sim, and have replaceable
batteries. I have this one, and it has all of the features you mention
except 32GB built in (but it has an SD card slot which provides me
with that): https://amzn.to/2jQA12b

Looking at more recent models, I think this one would tick all the
boxes: https://amzn.to/30vN60j (It has a notched display, though,
which really irritates me, and has moved the fingerprint sensor to the
back, which I'm also not keen on, so I suspect I won't be upgrading to
this when I need to replace my current phone).

The current OnePlus lineup is dual active SIM. The 7 Plus does not have a notch
and uses the screen for fingerprint sensing.
