  1. Motorola reveals over-air wireless charging plans for new phones Motorola is the latest mobile maker to signal its intentions to bring remote wireless charging to future smartphone releases. The company has announced a partnership with a company called GuRu Wireless in a bid bring over-the-air wireless charging to its handsets, minus the need to place its best phones on a charging mat. In a press release, GuRu explains its proprietary technology can power ‘watts-over-meters’ energy transfers between a central wireless unit and a compatible device. This will bring about a “new generation of wirelessly powered devices,” Moto says. “GuRu RF Lensing powers devices at watts-over-meters, bringing a new wave of energy to consumer devices,” the media release says. “This proprietary technology revolutionizes the consumer experience and helps to remove power as an everyday concern. GuRu’s patented, miniature modules will enable devices to be powered at long range by precision power transfer. Motorola and GuRu, will work together to match Motorola’s rigorous requirements of quality, power efficiency and safety.” The release contains no mention on when the first phones packing the technology might be announced, but we can’t imagine it will be within the next couple of years. We’ve requested comment on the matter from Motorola and GuRu. Moto isn’t the only company seeking to innovate in this regard. Earlier this year Oppo and Xiaomi both outlined their vision for the future of wireless charging. Xiaomi’s planned tech would be able to deliver 5W of power around the room, using a base station, but has greater range. The new tech uses a base station containing 144 antennas, which can transfer energy to the phone using a “extremely narrow millimetre-wide beam” capable of transmitting continuous 5W charging (within a few metres) to a compatible smartphone. Oppo’s concept involves hovering the phone above the wireless charging pad. The phone is still able to receive charge at 7.5W over a short distance of 10cm or less, which might be ideal if you want to use and charge the phone at the same time Source: Motorola reveals over-air wireless charging plans for new phones
  2. Xiaomi announces Mi Air Charge tech capable of 5W wireless charging over several meters It's a tech demo for now, but Xiaomi says we've entered the era of true wireless charging Forward-looking: When it comes to gadgets, nothing is truly wireless unless there’s freedom of movement in the user experience. Wireless earphones accomplished this feat a few years ago, and it now seems that wireless charging has done so as well, according to Xiaomi. The company says its new Mi Air Charge technology can remotely charge multiple devices (5W each) over several meters without interference from physical obstacles. The Qi wireless charging standard that most electronics employ these days still requires the host and receiver to be in very close proximity, accepting no more than 4cm (1.6-inches) of distance for charging. And while power output has been gradually improving over the years, companies like Xiaomi have been coming up with their own proprietary fast-charging wireless solutions that have been recently touching an insane 80W, though with the distance limitation still in place. In its latest announcement, the Chinese conglomerate revealed Mi Air Charge, a technology which it says allows for true wireless charging “within a radius of several meters.” The in-house developed tech uses phased antennas for locating and steering radio waves to the receiving device that also has a built-in antenna array for converting these waves into electrical energy for charging. Xiaomi also notes that Mi Air Charge can simultaneously juice multiple devices at 5W, and that physical objects do not interfere with the tech’s charging efficiency. The company aims to make it work with smartwatches, wearables, and smart home products like desk lamps and speakers. Don't expect, however, for Mi Air Charge to appear on the market anytime soon since a Xiaomi executive tweeted in a response that the tech won't be arriving on consumer products this year. It remains to be seen how Mi Air Charge will affect Xiaomi's hardware prices going forward and whether users will trade their fast-charging equipment (cables, power banks, wall chargers) for 5W truly wireless charging. The company might also need to address concerns around safety and actually ship Mi Air Charge to prove that "it's not science fiction, it's technology."

  3. Xiaomi's 80W wireless charging tech can fully charge a 4,000mAh battery in just 19 minutes Xiaomi has previously demoed a 120W fast wired charging solution and a 50W fast wireless charging solution for smartphones. The latter can wirelessly charge a phone with a 4,000mAh battery from 0-100% in just 40 minutes. Now, Xiaomi has announced an 80W Mi wireless charging technology for its smartphones which it claims is "an order of magnitude ahead of similar solutions" offered by other brands. The company claims that its 80W wireless charging tech can wirelessly charge a 4,000mAh battery to 50% in just 8 minutes. A full charge takes just 19 minutes. OPPO had announced its 65W AirVOOC wireless charging solution earlier this year that could charge a smartphone with a 4,000mAh battery to full in just 30 minutes. The company used a dual charging coil solution to achieve these speeds, though it requires users to place the device vertically on the charger. Xiaomi has not detailed its 80W wireless charging tech and has only boasted about its charging speeds. It has posted a video showing the wireless charging technology in action. There's no word from Xiaomi as to when this 80W wireless fast charging tech will show up inside its smartphones and what the company is doing to effectively manage and dissipate the heat generated by charging a device this fast. The company already offers 50W fast wireless charging and 120W fast wired charging on the Mi 10 Ultra so it is possible that it debuts this 80W wireless charging solution on the device's successor next year.
