China’s new wireless charging regulations!
80W will become the standard, but the Apple iPhone suffered a disaster!
In recent years, cell phone charging technology progressed speed amazing, charging power from the initial 20W to 65W, and then progressing to today’s 120W and 240W. In August, 320W super flash charging came out. Fast charging so that charging time is greatly reduced, drink a cup of coffee, casually flip through a magazine of the time, and the phone can be from “empty blood” instantly restored to full power, with a high-capacity battery, a lot of consumers’ power anxiety is also cured. However, the progress described above in wired charging was due to “getting rid of the boundaries of the line” of carga inalámbrica, but presented another picture, three years ago a policy like the Wukong head of the golden hoop, so that many brands of flagship cell phones have to adhere to the 50W wireless charging power line, who do not dare to step over the minefield. Today, in wireless charging the gold hoop finally came “loose” There is good news, but also a few happy and a few sad: some cell phone manufacturers can finally let go of their hands and feet boldly do, but there are also cell phone manufacturers not loose, wireless charging power still have to cut another knife tearfully. According to the latest regulations of the Ministry of Industry and Information Technology, from September 1, including cell phones, laptops, wearable devices, including mobile communication terminals, wireless charging equipment operating frequency shall be in the range of 100-148.5kHz, 6765-6795kHz, 13553-13567kHz three bands, the rated transmission power of not more than 80 W. This new regulation lifted the previous This new regulation lifts the previous restriction that the maximum transmission power is only 50W.
In terms of charging power, Chinese cell phone manufacturers have always been at the forefront. As early as 2021, Xiaomi Lei Jun posted a blog, saying that the Xiaomi 11 Pro Magic Modified Edition realized 200W wired and 120W wireless charging in a laboratory environment, and 120W wireless charging of a 4000mAh battery took only 15 minutes.
But then China’s Ministry of Industry and Information Technology issued an exposure draft, requiring cell phones and other terminal equipment wireless power must be less than 50W, which also greatly limits the Android phone manufacturers in the wireless charging play. For example, the Millet MIX 4 released in 2021, its wireless charging power can reach a maximum of 100W, but in the way of the new regulations, millet officials can only default to open 50W wireless fast charging for this phone.
The new wireless charging regulations have landed, good news for Android phone manufacturers, but a little awkward for Apple. Apple’s iPhone models wireless charging when using MagSafe and Qi2 two wireless charging protocols, although the highest power is 15W, but it so happens that the two protocols work in the frequency band 360kHz, and not in the new requirements of the working band. And the new regulations, since September 1, to stop the production or import in China’s domestic sales, the use of wireless charging equipment does not meet the requirements of the regulations. That is to say, the upcoming iPhone 16 series or no longer be able to use 15W MagSafe or Qi2 protocol.
