Battery percentage #57

Closed ltguillaume closed 6 months ago

Would it be possible to display the current charge percentage of the battery? I found it pretty annoying of the original TomTom software that there wasn't a proper indication, but it at least showed when the device was fully charged. It would be really nice to have an indication (ideally the raw percentage) in TomTomWatch as well.

As you can see in my reverse engineering page I did not find a proper function to read out the current battery level. The battery level however seems to be logged every 30 seconds when performing an activity. So I could add it to the GPX (I don't see a real benefit from that other than to track how fast the battery discharges over time)...

You write 'but it at least showed when the device was fully charged'. Where did it show this?

Below the circle that indicated when it was syncing (blue) and charging (yellow), there were the words "Charging" or "Fully charged". The circle itself provided a very imprecise indication of the charging progress.

During activities battery level is logged. I don't know how to get the battery level when the device is attached to the PC...
