80 years on a battery charge

The micro LED--which is significantly smaller than conventional
light-emitting diodes--requires only a few billionths of an amp to
operate. Thus, it can survive for quite a while on a limited power
source. One of the researchers on the project had one running
constantly for two-and-a-half years on his desk. Then someone damaged
it while moving it around. One member of the group calculated that it
could last 80 years (assuming no accidents) on the power stored in a
coin-size battery.
