Shows the battery consumption over time and estimates how long the battery would last (better than the build-in estimation).

I don't know exactly how Garmin predicts how long the battery of a watch would last, but I have been unhappy with that prediction. Specially during power-draining activities the battery on my Instinct2 is drained much quicker than predicted. This app tries to solve that problem.
During a longer activity you can check how much battery charge you have lost so far in the last x minutes/hours and see how long your battery would last if you keep on using it the same way.
The battery status is collected every 15min and then used to calculate the battery drain between those data-points. The app displays how much the battery was charged/discharged over time (15min - 24h) and calculates how long the battery would last if the battery would be discharged at the same rate like on average during the displayed period.
The prediction is rather pessimistic, so it will always floor decimal results (an estimation of 5.9h will show 5h)
- add the app to your glance carousel
- in the glance view press the GPS button to view the battery graph
- in the graph view press the GPS button to view details of different time periods
- in the details view use the UP/DOWN buttons to cycle through the different time periods
- last 24h battery graph
- Garmin Instinct 2
- Garmin Instinct 2 Solar
If you think that tool would be also useful on your device please open an issue or contact me on twitter
- only calculates battery change till the last recorded data point not till now (this data can be already nearly 15min old)
- allow user to pick which time frame to show in the glance
- calculate battery change from the current time and not only between data-points
