Fibaro Motion sensor dead battery when status says 77%

[U5tabil 2]

So my first Fibaro died after 6 months of use. Not bad though considering how much i have fiddle around with it, testing a lot etc.

But what worries me a little is that the device never showed that it was starting to get low on power. The last state before it died was 77%. Anyone else have had this "problem"?

Here is my parameter changes:

 

 

Parameter, Value, Hex, Bit

Motion Sensor Sensitivity 1 8 8 1
Motion sensor blind time 2 0 0 1
PIR sensor window time 4 3 3 1
Motion alarm cancelation delay 6 5 5 2
Tamper Sensitivity 20 0 0 1
Illumination report threshold 40 50 32 2
Illumination reports internval 42 900 708 2
Interval of temperature measuring 62 900 12C 2
Temperatur reports interval 64 0 12C 2
Led signaling mode 80 0 0 1
