Control of a Display Panel of a Barcode Reader to Indicate a Battery Level

A controller of a data processing device is disclosed. The controller may receive, via a user input, a charge threshold associated with presenting a battery level indicator on the display panel. The controller may monitor, during a charging operation, a state of charge of the battery. The controller may determine that the state of charge satisfies the charge threshold. The controller may cause, during the charging operation, the display panel to indicate the battery level indicator.
