Some smartwatches struggle to make it through a single day. Some have a two day battery life. In my use, a Pebble Time watch has a battery life up to 8.5 days. Any way you cut it, charging is an issue for smartwatches.
Except the MATRIX PowerWatch – the tiny amount of current required to power it is generated using heat from your body. Strictly speaking, the heat gradient from the back of the watch (against you wrist) to the front of the watch (in contact with ambient air).
