My mother's watch has this annoying problem. I use Garmin charger + Garmin cable. My watches always charge perfectly, her VIVO5 is making me angry because when I insert the USB cable the heart rate light goes off (this is a sign that it has detected the cable) but it does not start charging. Sometimes it start charging after 5 minutes, other times it does not start unless I turn the watch off and on again. The contacts are clean, what should we do before returning it under warranty?
