A smart watch doesn’t require very much current. A ribbon cable should be more than sufficient for a device that can last days on a 185mAh battery. Especially since a ribbon cable is already delivering most of the power to the device’s main board.
But I agree that a soldered on battery isn’t a big deal.
At this size battery connectors add way too much bulk.
I mean you see a ribbon connector right there for the daughterboard, but yeah, maybe it’s too bulky for the current case design.
How much current does that thin ribbon cable carry? Battery connectors need to be more robust.

Should still be able to carry 1 amp, shouldn’t it?
