Is there a way to replace the battery on Android 8.1.0 smartwatch? I mean for devices with small square displays of ~139 mm.
In such a case, where to purchase the battery and how to replace it? I mean, when the manufacturer does not document or does not have a service to do it.

Aliexpress is always a good source.
It is not supposed to be replaced by the user.
A battery can be ordered from Aliexpress as @G1NT0N1C says, but due to the different connection types and controller chip types, it’s not easy at all.
The brand you purchased from has no customer service so the only option is ask for a replacement watch under warranty (if you have battery problems) but they will probably never reply to you.
