Nowadays we always need technology, one of which is a smartwatch, nowadays the relationship of this kind of device
with the natural environment is becoming more important to study because the power extraction that is commonly used
is through non-renewable energy. Recently, there has been a shift in the way batteries are charged on some devices,
including smartwatches, from wired to wireless charging. Wireless Charging is considered a transformational technology in
the world, many major manufacturers have invested in this technology. However, the current wireless charging mechanism is
considered slow and energy inefficient compared to wired charging. Such inefficiencies may in turn exacerbate the adverse
impact of smartwatches on the environment. This paper addresses the issue of energy inefficiency during wireless charging
of smartwatches by comparing different charging practices to identify energy saving opportunities. Overall the wireless off
state charging experiment was found to be more energy efficient than the other two states potentially saving 0.098 Wh and
likewise the wired based charging potentially saving 0.096 Wh . The highest average energy consumption in wired and
wireless charging occurs when the smartwatch is ON + WiFiON where wireless charging consumes 0.228 Wh while wired
charging consumes 0.205 Wh.
