WattUp Distance Wireless Charging Coming To Major-Brand Phone
Energous has revealed that a "tier 1" consumer electronics company has agreed to implement WattUp wireless charging technology in a number of consumer products, including a phone. WattUp is an RF-based wireless charging technology that can be implemented in a number of ways, including transmitters that can send power wirelessly up to 15 feet, using a large array of antennas and beam-forming technology to send focused energy in the 5.8 GHz radio band. Smaller transmitters using fewer antennas can be pocket-sized, but only send power about an inch. In both cases, typical power sent is about a half a watt, enough to charge a wearable, or trickle-charge a phone, although higher power is possible with more antennas and shorter distances. Energous representative Gordon Bell gave an example of a computer monitor with the company's transmitters built into the bezel, that could wirelessly charge any wearable device on the user's desk, or trickle-charge a phone. A wearable device might ship with a small WattUp charger in the form of a USB stick, eliminating the need for a wired charger and wired connector. WattUp receiver antennas are smaller than wireless charging antennas from competitors such as Qi. Energous expects this tier-1 manufacturer to release WattUp-enabled products by the end of this year or early next year. Further details about products and configurations has yet to be announced.

Apple Adopts Qi Wireless Charging, Teases AirPower Charge Mat
Apple today announced new iPhones that are for the first time capable of charging wirelessly. The company has adopted the Qi wireless charging standard for the iPhone 8, iPhone 8 Plus, and iPhone X.
Qualcomm Intros Wireless Charging Through Metal
Qualcomm today announced new technology that allows metallic handsets to charge wirelessly. Most wireless charging pads are tolerant of some metal in the charging field, but Qualcomm says it was able to boost the sensitivity enough, via Near Field Magnetic Resonance technology, to allow for wireless charging through metal handset enclosures.
Quick Charge 3.0 Promises Even Faster Device Charging
Qualcomm today revealed its third-generation rapid-charging technology called Quick Charge 3.0. The revised technology relies on what Qualcomm calls Intelligent Negotiation for Optimum Voltage (INOV), an equation that lets phones, tablets, and other devices determine just how much power they need at any particular point in time — all while remaining efficient.
