I have same problem, issue started after a software update on Fri 8 Sep. My Vioactive 4 won't charge or hold any sort of charge and won't connect to my phone via Bluetooth. I've emailed Garmin support but had no response. Anyone have a solution please…

Same story here.  Bought the VA4s for the wife.  Stock default settings, updated to V3.6, first charge not good result. Second got 6 days in smart watch mode as no activities recorded.  3rd charge it started doing strange things like freezing up and then…

Same issue. Bit of a swim with half charged watch. Ok, warm day but definetely below 60 degrees Celsius. Screen blacked out. No connection with app, no charging, nothing. All reset options tried, nothing, nada. In NL no option in mentioned link. Sent…

wow, if that difference wasn't cause by firmware changes or other factors that would be a huge battery degradation for rather short period of time. Have you charged your watch from 0-100% or used some gentle charge policy like 25-75% to prolong battery…

Are you using a downloaded watchface?  I found that I could only get a few days on a full charge using a non-stock watchface.  Using a build-in venu3 specific, I can go about 9-10 days on a charge - that's with sleep and spo2 tracking at night.

Battery issue. I had same problem, charged to 100% in morning and by afternoon it was at 30%. then I let the battery drain to 0, and then charged it to 100%. After doing this I haven’t faced this issue again and battery now lasts for 8-10days. 

Is it fully charged yet? Once it is, can you reset the device to factory settings?
