A fully charged employee badge lasts about 200 days if its content changes twice a day. The e-paper display uses power only when its content changes, so a badge whose content rarely changes lasts longer.

- On the badge: press and hold the button on the back for about 4 seconds. The badge shows its battery percentage and MAC address. Anyone holding the badge can do this.
- In the Joan Workplace mobile app: admins and office managers can see the battery level of badges in Bluetooth range.
The MyJoan web portal doesn’t show battery levels for employee badges. Employee badges only connect when they’re near a phone running the Joan Workplace mobile app, so the portal has no current reading.
An empty badge shows a red battery icon at the bottom centre of the display. The rest of the content stays on screen, because an e-paper display keeps its last image without power. A badge that still shows an employee’s details can therefore be empty, so look for the red icon.
Place the badge on any Qi-compatible wireless charger. Joan doesn’t sell chargers yet. We’re testing Qi chargers and will recommend one here.
