Technical information

This function uses a lot of the battery resources of the phone and the watch. If the phone no longer has enough battery, the watch will continue to guide you. However, in this extreme emergency situation, the minimum remaining life with just the watch battery cannot be indicated.

GPS signal detection is sensitive to electromagnetic disturbances and geographic location. It is really necessary to hold the watch flat, facing upward and a long way from metal surfaces to obtain the best possible GPS signal reception.
