I think there's a kind of mini battery built into electronic devices which is there to store settings - these eventually wear out.

Typically this is just a capacitor. Capacitors have much longer service lives than batteries, but store much less energy, so they discharge in a short time. The capacitor gets its recharge from the removable battery.
