- My vivoactive 4s is 1 year and 2 months old. For that time, I was happy with my battery life and only had to charge a couple times per week. 2 days ago, the watch froze up. After turning it off and back on, it would no longer connect to my phone. I did every troubleshooting tip I could find online, but ultimately had to reset the watch. I have gone through everything and have verified that I have all settings the same as before the freeze up. I do have it set to have Bluetooth connection to my phone and I have activity tracking on, but I always had those on before, too. I do not use it for texts. I have the headphones off so that they are no constantly trying to connect, and I turn on the connection when I go for a workout. Now the battery is draining fast and needs recharging today after 9 hours. It seems like it is not just a routine battery life issue at this point, but that something went bad inside and I am likely to need a replacement. Has anyone else had this type of sudden dramatic deterioration in their battery?
