BatteryManager.chargingTime

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Indicates the amount of time, in seconds, that remain until the battery is fully charged.

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.

Syntax

var time = battery.chargingTime

On return, time is the remaining time in seconds until the battery, which is a BatteryManager object, is fully charged, or 0 if the battery is already fully charged. If the battery is currently discharging, this value is Infinity.
