Some 2 weeks ago I bought a Vivoactive 4. The battery lasted normally a couple of days.
Recently there was a firmware upgrade, the device is on 4.40.0.0. Yesterday evening I had 20%, then it died during the night. I charged it to 100% at 10am, at 2pm I got a notification that battery is low at 10%, within 15 mins it turned off. I am just sitting in my office, no GPS, activities.
Any one else having a similar issue?
