After I updated my Garmin watch vivoactive 4s a couple of weeks ago, the battery life has been much shorter. It will only last 2 days max and before the update it lasted about 4-5 days. I have reset it back to factory settings and it has not helped. I have checked the common things that might be using up battery life such as gps, music, etc. and they are not on. Any tips on how to get my battery life back to normal?
