Battery Life in Smartwatch Mode

Former Member

Hi, I just bought the Forerunner 945 and used it over the last couple of days. While it is a great watch, I am a bit underwhelmed about the battery life. It should last up to two weeks in Smartwatch Mode but it seems to use 12-14% per day with little usage which would just give me half of that (this is without doing exercises...as said, minimal usage, which is checking pulse from time to time or reading an incoming msg). I have mostly just factory settings on. I also already checked the tipps on the garmin side of how to optimize battery life (but not going to switch off pulse measurement as this should be part of a Smartwatch Mode). I have it paired with an iPhone Xr. Any views or similar experiences?

Many thanks,
Marc
  • Did you see a big improvement once you removed the widgets? Mine lasts about a week, half of the advertised lifetime

  • Good gracious I don't know what has changed but the last week I am averaging about 1.5% per hour whereas before I had a "long term" average of about .7%/hour.  So for some reason I am doubling my rate.  No changes on watch faces and I am still around 1-1.5 hours of GPS use per day.  The battery on this thing has been a roller coaster to say the least.
