Share with friends and circle of friends with wechat scan QR code < / P > < p > on January 29, Lei Jun announced on social media today that he officially released the space isolation charging technology, which can realize the 5-watt long-distance charging of a single device. < / P > < p > Lei Jun said that the space isolation charging is realized by Xiaomi's self-developed space isolation charging pile, with five built-in phase interference antennas, which can carry out millisecond level spatial positioning for mobile phones and accurately detect the location of mobile phones. The phase control array composed of 144 antennas can directionally transmit millimeter waves to mobile phones through beamforming, and the mobile phones can receive them through micro beacon antennas, which can realize 5-watt long-distance charging within several meters . < p > < p > Lei Jun said that Xiaomi's self-developed space isolation charging technology will provide space isolation charging for smart watches, bracelets and other wearable devices. In the future, the living room, including speakers, desk lamps and other small smart home products, can realize wireless power supply design, get rid of the shackles of wires, and truly realize the living room wireless.

Lei Jun issued the personal official account" Lei Jun: millet self research spaced charging technology, 17 patents. " 》。 He said: < / P > < p > in the field of wireless charging, Xiaomi has always been a well deserved leader in the industry and is far ahead. < / P > < p > since 2018, Xiaomi has repeatedly broken the < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E6%89%8B%E6%9C%BA%E8%A1%8C%E4%B8%9A "Style =" box sizing: inherit; color: rgb (0, 140, 210); text decoration: none; "> wireless charging record of mobile phone industry < / a >. In August 2020, Xiaomi launched the 80W wireless second charging technology in the world, with charging efficiency almost comparable to the fastest wired fast charging technology on the market. Today, we have achieved another revolutionary breakthrough: we officially released the space isolation charging technology and took the lead in realizing it on Xiaomi 11! < / P > < p > < / P > < p > imagine the charging mode in the future? Maybe you don't need any < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%85%85%E7%94%B5%E7%BA%BF "Style =" box sizing: inherit; color: rgb (0, 140, 210); text decoration: none; "> charging cable < / a >, charging base, whether the mobile phone is carried in the pocket or in the hand, can realize automatic space charging. This kind of scene only exists in science fiction movies, has become a reality. < / P > < p > < b > self developed 17 technical patents of the air separation charging system < / b > < / P > < p > millet air separation charging, the core of which lies in the spatial positioning and energy transmission. The self-developed isolated charging pile has five phase interference antennas built in, which can locate the mobile phone in millisecond space and accurately detect the location of the mobile phone. A phase control array composed of 144 antennas transmits millimeter wave directionally to mobile phone through beamforming. < / P > < p > on the mobile phone side, Xiaomi has also developed a miniaturized antenna array with built-in "beacon antenna" and "receiving antenna array". Beacon antenna broadcasts position information in the space field through low power consumption. The receiving antenna array composed of 14 antennas converts the millimeter wave signal emitted by the charging pile into electric energy through the rectifier circuit, realizing the space isolation charging experience of science fiction. < / P > < p > at present, Xiaomi air separation charging technology has realized 5-watt long-distance charging for a single device within a radius of several meters. Not only that, multiple devices can also be charged at the same time (each device supports 5 watts), and even the foreign matter shielding does not reduce the charging efficiency. < / P > < p > < b > in the future, the living room will fully enter the wireless era < / b > < / P > < p > in the near future, Xiaomi's self-developed air separation charging technology can also provide air separation charging for smart watches, bracelets and other wearable devices. In the future, the living room, speaker, desk lamp and other small smart home products can realize wireless power supply, completely get rid of the shackles of wires, and truly realize the living room wireless. < / P > < p > < / P > < p > < b > the free scheme of Xiaomi 11 charger failed, only 5% of which were not selected, and environmental protection became a false proposition? < / b > < / P > < p > Xiaomi 11 is the second mobile phone to cancel the charger, following the cancellation of the charger for the full range of iPhone 12, iPhone 11, iPhone XR and iPhone se (the second generation) in 2020. However, the practice of Xiaomi is not quite the same as that of iPhone. Apple is a one size fits all approach. No matter whether you have a charger or not, you have to add 149 yuan for extra purchase if you want. Xiaomi uses another way. Under the condition of keeping the same price, it introduces the standard version and the package version respectively. The standard version does not have a charger, while the package version has a charger, so users can choose according to the actual situation. < / P > < p > however, according to the data released by Xiaomi, the sales of 1.5 billion yuan means that about 375000 Xiaomi 11 have been sold. Among them, 20000 people chose the standard version and did not want a charger. This proportion is only 5%, which can be said to be very low. After all, the number of users with chargers at home must be much higher than this proportion. In this way, more people choose the suit version under the psychological effect of not being in vain, and environmental protection has become a false proposition. This result shows that Xiaomi's strategy of providing chargers free of charge for users in need of chargers is a failure, and basically has not played a role in environmental protection. < / P > < p > in fact, many people are not particularly concerned about environmental protection, because it is far away from life. In this case, it is reasonable that if we take a voluntary approach, the effect will not be good. If you really want to protect the environment, it may be the best way to cancel the charger. After all, the price of 149 yuan is not cheap, which is enough to make people think about it for a while. Many users will give up buying chargers in order to save 149 yuan, so as to achieve the purpose of environmental protection.

当然这样的强制做法在开始的时候会引起一定的反感，但是时间久了消费者也会变得无感，就像是不送耳机一样，开始有人不能接受，现在不送耳机或许成?
