Alongside the evolving smartphone industry develops another one: accessories for these can’t-live-without devices, and particularly smartphone cases. Most of them are meant to protect the smartphone in case you drop it, other are designed with a heightened sense of fashion and put vibrant colors and intricate patterns on it, some add juice to the battery life, some add protection to the holder, while others add physical keyboards for those less attracted to the touchscreens. The possibilities seem endless. Nikola Labs, an Ohio-based company, has found the way to build a case for iPhone 6 that converts RF (radio frequency) energy to DC power, in other words it pulls battery power out of thin air. Incredible? It sure sounds so, but behind this magic trick there is a scientific explanation and an issue in meeting your great expectations after reading up to this point. According to Nikola Labs co-founder Dr. Rob Lee, over 90 percent of the smartphone’s energy is lost into the environment while spending it to forge data and voice connections by using radio frequencies. Besides protection, the case has a harvesting antenna and a RF-DC power-converting rectifier circuit that through Nikola Labs’ formula can be collected and redirected to the battery life. However, this can only add about thirty percent of battery life to your iPhone 6; this is a slow process as well. On the positive side, as long as the case is connected to the smartphone, the process of collecting and reusing the wasted energy is ongoing. This translates into a slower battery depletion and not into a sudden burst of charging process. The case doesn’t have an internal battery or the capacity to store the energy, thus having a thinner figure than the already popular Mophie case. The company...
