ACTION_CHARGING

static val ACTION_CHARGING: String

Sent when the device's battery has started charging (or has reached full charge and the device is on power). This is a good time to do work that you would like to avoid doing while on battery (that is to avoid draining the user's battery due to things they don't care enough about). This is paired with ACTION_DISCHARGING. The current state can always be retrieved with isCharging().

Value: "android.os.action.CHARGING"

ACTION_DISCHARGING

static val ACTION_DISCHARGING: String

Sent when the device's battery may be discharging, so apps should avoid doing extraneous work that would cause it to discharge faster. This is paired with ACTION_CHARGING. The current state can always be retrieved with isCharging().

Value: "android.os.action.DISCHARGING"

The time period over which the average is computed may depend on the fuel gauge hardware and its configuration.

Value: 3

BATTERY_PROPERTY_CURRENT_NOW

static val BATTERY_PROPERTY_CURRENT_NOW: Int

Instantaneous battery current in microamperes, as an integer. Positive values indicate net current entering the battery from a charge source, negative values indicate net current discharging from the battery.

Extra for android.content.Intent#ACTION_BATTERY_CHANGED: integer containing the resource ID of a small status bar icon indicating the current battery state.

Value: "icon-small"

EXTRA_LEVEL

static val EXTRA_LEVEL: String

Extra for android.content.Intent#ACTION_BATTERY_CHANGED: integer field containing the current battery level, from 0 to EXTRA_SCALE.

Value: "level"

EXTRA_PLUGGED

static val EXTRA_PLUGGED: String

Extra for android.content.Intent#ACTION_BATTERY_CHANGED: integer indicating whether the device is plugged in to a power source; 0 means it is on battery, other constants are different types of power sources.

Value: "plugged"

EXTRA_PRESENT

static val EXTRA_PRESENT: String

Extra for android.content.Intent#ACTION_BATTERY_CHANGED: boolean indicating whether a battery is present.

Value: "present"

EXTRA_SCALE

computeChargeTimeRemaining

open fun computeChargeTimeRemaining(): Long

Compute an approximation for how much time (in milliseconds) remains until the battery is fully charged. Returns -1 if no time can be computed: either there is not enough current data to make a decision or the battery is currently discharging.

getIntProperty

open fun getIntProperty(id: Int): Int

Return the value of a battery property of integer type.

getLongProperty

open fun getLongProperty(id: Int): Long

Return the value of a battery property of long type If the platform does not provide the property queried, this value will be Long.MIN_VALUE.

getStringProperty

open fun getStringProperty(id: Int): String?

Return the value of a battery property of String type. If the platform does not provide the property queried, this value will be null.

isCharging

open fun isCharging(): Boolean

Return true if the battery is currently considered to be charging. This means that the device is plugged in and is supplying sufficient power that the battery level is going up (or the battery is fully charged). Changes in this state are matched by broadcasts of ACTION_CHARGING and ACTION_DISCHARGING.
