You can see the battery status of ZEEQ in the ZEEQ app by clicking on the settings (the 3 stacked lines in the top left of the app). Once pressed you will see a battery icon showing the ZEEQ battery status.
You can also check the ZEEQ battery status when you power up your ZEEQ. The ZEEQ remote will blink white 1 time for each 25% of ZEEQ battery charge.
