My main concern for having a dedicated GPS logging device is the battery drain of the tracking apps on my phone. Used to have a Transystem 747ProS [1] which uses a Nokia BL-5C battery and would last a few days. However, that device was quite dated even then and its accuracy often lacking.

Now I am carrying a dedicated Android phone with me (a Xiaomi Mi 11 Lite 5G) on which I have PhoneTrack [2] installed. The app starts tracking as soon as the phone is moving and saves all the data on device. I used to have an instance of Owntracks [3] running, but now I just run a simple Flask app which pipes the GPS points to a PostGIS database on my local network when I am home. To visualize the tracks, I import them into QGIS. As the phone is solely used for tracking and only when I take it with me, the battery lasts about three days.

Very interesting! Thanks for this. I am worried about the same thing so might end up having to do this.
