Beschreibung
 
This widget calculates a battery lifetime prediction for different types of usage.

The lifetime-calculation is based on the following "100% charged" values:

- GPS & GLONASS: 15h

- GPS: 20h

- Activity Tracking: 28d

- Clockusage only: 90d

Will update this values based on my experiences with my own FR920xt and your feedback.

Please note that this is a rough estimation. The battery lifetime depends on a lot of 

influencing factors like number of cycles, operating time or outside temperature.


Versions & Corrections:

v 1.4: changed calculation basis for battery lifetime (more defensive)

v 1.6: "division by zero"-problem at battery level 0% solved

v 1.7: fixed problems with "on update"

v 1.9: Battery percentage with 1 decimal place

v 2.2: No refresh within the app for no battery consumption after startup

v 2.3: Widget-Version

v 2.6: more defensive lifetime calculation. More efficient coding for less CPU-usage at onUpdate

v 2.7: changed calculation GPS&GLO 15h, Act-Tracking 28days

v 2.9: corrected demo coding entries

v 3.0: changed in code documentation

v 3.2: improved algorithm (less CPU usage)

v 3.28: corrected calculation problem at 0.0% capacity

v 3.31: changed accu capacity calculation - displays now the percentage of rest-lifetime instead of percentage based on battery-voltage

v 3.32: support for epix

v 3.3.5: changes for SDK compatibility
