Is there a backup battery similar to a CMOS on the circuit board of a XUMO remote?

As far as we’re aware, the Xumo Stream Box remote does not contain a separate CMOS-style backup battery like you’d find on a computer motherboard.

The remote is powered directly by the removable batteries, and once those are removed, the remote should fully power down. Any pairing or configuration information is typically stored in non-volatile memory inside the remote itself, meaning it can retain settings without needing a backup battery to stay “live.”
