A 3mA draw seems high even for this circuit. Maybe putting the LEDs on a constant duty cycle PWM would reduce current consumption, oftentimes attainable without any reduction in perceived brightness.
I wonder if it's possible to also have a series resistor between the battery and microcontroller to bring it down to its lower end of acceptable voltage range for longer. Just a thought.

A hearing aid battery with a small boost converter for the LEDs should give you several days of power per battery, and is about the same size as the battery used here.
