// We can safely ignore this approach for most (or all) boards because MCU turned off
// earlier than battery discharged to 2.6V.
//
// Unfortanly for now we can't use this killswitch for RAK4630-based boards because they have a bug with
// battery voltage measurement. Probably it sometimes drops to low values.
