BatteryManager.chargingTime
The BatteryManager.chargingTime
property indicates the amount of time, in seconds, that remain until the battery is fully charged or 0
if the battery is already fully charged. If the battery is currently
discharging, its value is
Infinity
. When its value changes, the chargingtimechange
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.
