My Garmin vivo 3 battery lasts maybe 7 hours. It also has difficulty tapping on even when it is charged. Do I replace the battery? Is this a potential class action as happened to Apple for their batteries? Sounds like planned obsolescence to me. It has gotten quickly worse over the course of the last month or so. Nothing helps. I am very disappointed in this. I bought one for Christmas for my brother and he is having the same problem. His is only a few months old. Shoddy product.
