Lu Weibing reveals more details about Xiaomi's 100W fast charge technology

Xiaomi teased its 100W "Super Charge Turbo" fast charging technology capable of completely charging a 4000mAh battery in just 17 minutes a year ago.

Technical Implementation: Weibing didn't get into the details about the implementation of 100W Super Charge Turbo, but said it requires an ultra-high voltage charging solution. The battery capacity loss encountered in 100W fast charging estimates up to 20% when compared with 30W PD fast charging.

In the Weibo post, Weibing mentions 5 hard technical aspects to be considered while implementing 100W fast charging.

Battery Capacity Loss: Batteries don't like heat, which is the reason why fast charging cells are quicker to lose their capacity over time. In essence, a 5000mAh battery's capacity would practically reduce to 4000mAh. He said that it is in the early-stage of mass production but as not revealed much in terms of timeline.

Performance: The company wants to make 100W Super Charge Turbo sustainable and not just implement it with the resources now available.

Security: It will be offering multiple security features in the device with support for 100W charging, such as motherboard, battery, overcharging, voltage, etc.

Multiple charging scenarios: While 100W Super Charge Turbo is a wired charging tech, Xiaomi is also considering wireless charging scenarios as well as charger compatibility. Weibing also asked users whether they would prefer a 4,000mAh battery with 100W Super Charge Turbo technology or a 5,000mAh battery with 30W PD fast charge technology. Given that 5G phones require a lot more power, the battery capacity losses he refers to earlier become even more of a concern with devices using the next-gen networking tech, making companies wary of increasing charging speeds at the expense of the already shorter battery lives of 5G devices.

Apart from these, Lu Weibing has revealed that the company has reached the stage where it seems that the 100W fast charging technology could be mass produced in the near future.
