Struct BatteryStatus 

pub struct BatteryStatus {
    pub voltage: u16,
    pub connected: bool,
    pub full: bool,
}

The battery status info.

Contains only stats that can be accessed from the hardware. It’s responsibility of firefly-runtime to calculate State of Charge and any other metrics it might need.

Fields

voltage: u16

The current voltage of the battery.

A healthy li-ion battery voltage ranges from 3.0V fully discharged to 4.2V fully charged at 25°C. However, the range changes with age, temperature, and star alignment (the last one is a joke, probably).

Also, the firefly-hal Device implementation doesn’t define the units in which voltage is returned. it can be volts, microvolts, or anything else. The only promise is that it linearly correlates with voltage.

connected: bool

If true, the device is connected to a charger.

It indicates that the battery is charging, unless it’s full.

full: bool

If true, the device is fully charged.
