power_supply_properties.proto:19Power supply status sent from powerd to Chrome.
optional PowerSupplyProperties.ExternalPower external_power = 14
Current state of the external power source.
optional string external_power_source_id = 17
ID of the PowerSource that is currently providing power to the system.
repeated available_external_power_source = 18
Currently-connected external power sources.
optional PowerSupplyProperties.BatteryState battery_state = 15
Current state of the battery.
optional double battery_percent = 7
Estimated battery charge as a percent of its total capacity, in the range [0.0, 100.0]. Unset if a battery isn't present.
optional int64 battery_time_to_empty_sec = 5
Estimated time until the battery is empty, in seconds, or zero if the battery isn't discharging. -1 if the estimated time would be huge (e.g. because the current is zero or close to zero). Unset if a battery isn't present.
optional int64 battery_time_to_full_sec = 6
Estimated time until the battery is full, in seconds, or zero if the battery isn't charging. -1 if the estimated time would be huge (e.g. because the current is zero or close to zero). Contains the best estimate for when the battery will be full when Adaptive Charging is delaying charge. If there is no current estimate for when Adaptive Charging will finish, the value is zero. Unset if a battery isn't present.
optional bool is_calculating_battery_time = 12
True when |battery_time_to_*| can't be trusted, e.g. because the power source just changed. Unset if a battery isn't present.
optional double battery_discharge_rate = 16
The battery discharge rate measured in W. Positive if the battery is being discharged, negative if it's being charged, or unset if a battery isn't present.
optional bool supports_dual_role_devices = 19
True if it is possible for some connected devices to function as either sources or sinks (i.e. to either deliver or receive charge).
optional double battery_voltage = 20
Current battery voltage level.
optional string battery_vendor = 21
Battery manufacturer reported in sysfs as either "manufacturer" or "vendor". Ex.: "SIMPLO"
optional int64 battery_cycle_count = 22
Battery cycle count representing the total number of times all the battery's power has been used.
optional string battery_serial_number = 23
Battery serial number reported in sysfs.
optional double battery_charge_full_design = 24
Battery design capacity measured in ampere-hours (Ah).
optional double battery_charge_full = 25
Battery full capacity measured in ampere-hours (Ah).
optional double battery_voltage_min_design = 26
Battery voltage min design measured in V.
optional double battery_charge = 27
Current battery charge right now, measured in ampere-hours (Ah).
optional string battery_model_name = 28
Battery model name reported by |model_name|.
optional double battery_current = 29
Battery current as of now, measured in amperes (A).
optional string battery_technology = 30
Battery technology read from sysfs.
optional string battery_status = 31
Battery status read from sysfs.
optional double preferred_minimum_external_power = 32
The device's preferred minimum external power input in watts (W). When requesting the user use a higher-power external power source, this value can be displayed.
optional bool adaptive_charging_supported = 33
Indicates if the system supports Adaptive Charging required functionality.
optional bool adaptive_delaying_charge = 34
Indicates whether charging to full is delayed by adaptive charging. If so, |battery_time_to_full_sec| indicates the time until the battery is planned to be fully charged. The planned time to fully charge the battery may change over time based on predictions from adaptive battery.
optional bool adaptive_charging_heuristic_enabled = 35
Indicates if Adaptive Charging is currently allowed by its heuristic, which disables Adaptive Charging if the charging behavior of the user won't benefit from the feature. Unused unless Adaptive Charging is supported on the system.
Next ID to use: 36
Used in:
FULL = 0
The battery is full or close to full.
CHARGING = 1
The battery is being charged but is not yet full.
DISCHARGING = 2
The battery is discharging. Note that an external power source may be connected but not supplying enough power to offset the system's instantaneous power consumption. This state is also used if the battery is neither charging nor discharging (i.e. current is zero) in a non-full state, which may indicate a battery defect.
NOT_PRESENT = 3
The system doesn't have a battery.
Next value to use: 4
For any of these power sources, the system may be consuming power at a high enough rate that the battery is discharging rather than charging; see BatteryState. See the PowerSource submessage's |type| field for more details about the active power source.
Used in:
AC = 0
AC/line/mains or USB PD power is connected. This is typically the highest-power source that can be attached to the system.
USB = 1
A low-power USB source (SDP, DCP, CDP, or ACA) is connected.
DISCONNECTED = 2
No external power source is connected.
Next value to use: 4
message
power_supply_properties.proto:50Details about a potential source of power to the system.
Used in:
optional string id = 1
Opaque ID corresponding to the device. Do not use this for any purpose beyond comparisons with |external_power_source_id| or as an argument to powerd's SetPowerSource D-Bus method.
optional PowerSource.Port port = 7
The charging port to which this power source is connected.
optional PowerSource.Type type = 8
Power source type.
optional string manufacturer_id = 4
Raw strings read from |manufacturer| and |model_name| files in sysfs.
optional string model_id = 5
optional double max_power = 6
Maximum power this source is capable of delivering, in watts.
optional bool active_by_default = 3
True if the power source will automatically deliver charge to the system when connected (assuming there isn't another |active_by_default| source doing so). If false, the source will not deliver charge unless requested to do so by the user.
Next ID to use: 9
Used in:
UNKNOWN = 0
The location of the port is unknown, or there's only one port.
LEFT = 1
Various positions on the device. The first word describes the side of the device where the port is located while the second clarifies the position. For example, LEFT_BACK means the farthest-back port on the left side, while BACK_LEFT means the leftmost port on the back of the device.
RIGHT = 2
BACK = 3
FRONT = 4
LEFT_FRONT = 5
LEFT_BACK = 6
RIGHT_FRONT = 7
RIGHT_BACK = 8
BACK_LEFT = 9
BACK_RIGHT = 10

OTHER = 0
Unspecified type.
MAINS = 1
Dedicated charger. Typically single-purpose and non-USB (e.g. barrel jack plugs). Corresponds to kernel-reported type "Mains". This source is reported by the ACPI driver and may also appear (along with a USB_PD source) on Type-C-only systems if the ACPI driver is present.
USB_C = 2
USB Type-C, including dedicated Type-C chargers. Typically >= 7.5W. Corresponds to kernel-reported types "USB_C", "USB_PD", "USB_PD_DRP", and "BrickID".
USB_BC_1_2 = 3
USB Battery Charging r1.2. Typically <= 7.5W. Corresponds to kernel-reported types "USB", "USB_ACA", "USB_CDP", and "USB_DCP".
