When I plug in my Vivosport for charging, I see a gold icon of a vertical battery. It has a tip at the top for the battery connector and a horizontal line within the battery image rectangle at the bottom of the rectangle. The small horizontal line never changes or enlarges. This icon looks like a different icon from the battery charging icon. I would call the charging icon a pixel based symbol and this one looks like line art.
When I plug the device in, this image appears for a few seconds and then disappears.
My device does not charge and does not work.
I think this icon means you have a battery that no longer will charge.
Can anyone confirm this or otherwise identify the meaning of the icon.
