In recent times, there has been widespread innovation in the smartphone industry. One area that has seen a major overhaul is the battery capacity and charging power segment. Just a few years ago, we were talking about 18W charging maximum. Presently, 120W fast charging is already available. The speculations so far are that 200W fast charging is already in the works. At the end of last month, Xiaomi did some upgrades to the Xiaomi Mi 11 Pro and it successfully supported 200W wired and 120W wireless fast charging. This means that the device breaks both the wired and wireless charging records.
Recently, Xiaomi solicited some questions about its "200W wired" & "120W wireless" charging technology. The company invited Mi Fan representatives to ask Xiaomi engineers face to face. The first question to Xiaomi engineers is whether the 200W fast charging is safe or not. Obviously, this will be the first question that anyone would ask.
Xiaomi's response shows that this charging capacity is as safe as the 120W charging capacity. The engineers said that the 200W fast charging is safe. They further claimed that the 200W fast charging technology has gone through a long process from research and development to release. There are safety procedures from the charger end to the motherboard end to the battery. In the end, Xiaomi claims that this charging capacity has up to 40 safe and active protective measures.
Mi Fan also mentioned the impact of 200W fast charging on battery life. Xiaomi engineers replied that after 800 cycles of use, the energy of Xiaomi’s battery remains above 80%. This is much higher than the Chinese requirement of "after 400 cycles, the battery life should not be less than 60%". This means that Xiaomi's 200W fast charging beats the Chinese industry standard.
Xiaomi’s 200W wired fast charger can charge a 4000 mAh battery from 0% to 100% in 8 minutes. This charging capacity will achieve 10% in 44 seconds, and 50% in 3 minutes. This is the first time that wired charging has entered the ten-minute timeline. The Xiaomi 120W wireless fast charging can be used to charge a 4000 mAh battery to 100% in 15 minutes. This is also the first time that wireless charging has broken through the 100-watt mark.
In addition, Xiaomi's official WeChat account also used 8 pictures to explain some doubts about the "200W wired" & "120W wireless" charging technology. When it comes to safety, one has to talk about heat generation. This time the Xiaomi 200W fast charge uses a parallel design. The power conversion efficiency is 98.6%, which will be the industry's highest if true. In terms of software, Xiaomi adopts a multi-level gradual current algorithm.
