BatteryManager.dischargingTime
The BatteryManager.dischargingTime
property indicates the amount of time, in seconds, that remains until the battery is fully
discharged,
or Infinity
if the battery is currently charging rather than discharging,
or if the system is unable to report the remaining discharging time.
When its value changes, the dischargingtimechange
event is fired.
Note: Even if the time returned is precise to the second, browsers round them to a higher interval (typically to the closest 15 minutes) for privacy reasons.

<div id="dischargingTime">(discharging time unknown)</div>
