    Itty Bitty Joule Thief

    The circuit will reduce the life of the transistor because the -ve spike is developed across the transistor base-emitter as well as the +ve that actually drives the transistor On . They don't like reverse voltage above about 3V.. You should have a decently rated diode eg 1n4001 in circuit with the +ve end to the Base and the -ve end to the -ve line.
