Ask HN: Best Android phone under $400?

I like the Sony XPeria XA2 phone, which doesn't seem to be shipped with a weird android version, has a lot of custom ROMs and is well-supported.

how is the battery like?

If you would have asked me a few weeks ago I would have said a Honor 10. As of right now it would probably have to be a Xiaomi Mi9 SE.

The Pixel 3A seems like a good fit. Just picked one up and am quite impressed with it so far.

the small screen or the big one? how is the battery like?
