Runtime
Runtime is how long the machine works on a full charge. The figure in product sheets is declared by the manufacturer and refers to specific conditions (set voltage, load, temperature): in real use it can differ.
Why it matters: It is one of the most useful specifications to compare on wireless machines, but it should be read with caution because measuring conditions are not standardised.
