Forerunner 45 sometime doesn't turn on

Since I only use my watch for tracking my runs and hikes, and not as a daily activity tracker, I usually turn it off in the meantime. However, I had two times now in the past month where the device had problems turning on again, despite it being (nearly fully charged). What eventually helped was connecting it to the charger again, and pressing buttons for a long time (30 seconds or so).

My Forerunner 45 runs the latest software (3.10). I also have the impression that the problem started after the 3.xx software updates. Is this a known issue, or may it be hardware related? Apart from this issue (which has occurred twice now), the watch is completely fine.

Thanks for any recommendations!

  • I am having the same issue as everyone else.  Only had the Garmin 45S for 2 months, worked fine with my old Samsung for a good few weeks, no problems.  Changed by phone to a new iphone X, so now it won't stay connected or sync properly with my new Iphone X.  For some reason as soon as I leave the house for a run and don't take the phone with me, it won't connect when I get back home and sometimes the phone can be within arms reach and still not stay connected!!!   Having to keep switching the Garmin off and then rebooting it again, which sometimes I can't get it to switch back on!  Losing faith in the item.
