This night woke up at 4am because my forerunner 945 had only 10% battery left and signaled. Few seconds later it went out completely. This morning on the charger checked.....no update (still firmware 5.0) and maps still unchecked (seemed the reason for battery drain few months ago). This is really frustrating for such a fine watch.
Anyone else have sudden battery drain returning even with maps switched off? Any solutions?
