Battery lifetime and lifetime of other components?

Sorry for not explaining my measurements in more detail in the first place.

I've used a CR2032 coin cell as energy source and measured the voltage drop on a 10R high precision resistor (uCurrent). Therefore the see-saw supposedly shows the different phases of the uC cycle:

1. power up
   
2. pre-processing
   
3. transmit (I assume 3 consecutive re-transmits)
   
4. power down
   
   

I'm using the DSO's math functions to calculate the integral (shown in purple) on channel 1 (yellow). The integral of this particular measurement is 11.44uU = 11.44uA/advertisement. However measurements are never exact. Hence I decided to state the value at ~12uA/advertisement, in my post above.
