Is there any impact on watch battery life with Garmin Connect Mobile constantly running in background?

It seems I can't get weather updates without GCM running, but I'm concerned if there will be any impact on watch battery life when constantly syncing with GCM via bluetooth.

  • Just solved!
    Keep Connect IQ app running in the background also updates weather, without syncing health data with phone.

  • Maximizing battery usually comes at some sacrifice, so if you have access to charger... yes you would likely want to keep the automatic sync with GCM/phone enabled.  I would think that if you had it off, but had wifi setup for at home/office/etc that it would still get some updates when near your wifi areas.  If I go on a super long ride or ultra run, often i will turn off wifi (optical HR, screen dimmed, turn off some sensors that I am not using on activity, etc) on watch.  Probably all marginal gains of time... but better than watch dieing 10hrs into a run/ride.
