Very high battery consumption during tracking
I have been using the app for some years and I like it very much. But I found always the battery usage during tracking little bit too high comparing to other tracking apps like OsmAnd.
I can monitor the cpu usage of your app during tracking and it's constantly using around 1% of the cpu time. Which forces the governor to increase the voltage and by this it eats up my battery in about 4-5 hours which is just not enough for a tracking. If the tracking is paused the cpu is still used. Thus it's not related to the accuracy of the tracking and so on ... If no tracking the app is stopped when the screen is off so no problem.
Mobile data is disabled during tracking to conserve energy.
I attache a screen shot which was taken when your app and the OsmAnd were tracking movements.
