Xiaomi hosted the technical conference organized by the Wireless Power Consortium (WPC) at its headquarters in Beijing. At the event held between 22-25 June, engineers of many technology companies, including Apple, Google, Huawei, Honor, Oppo and Vivo, participated in the new generation Qi 50W wireless charging standard evaluated its technical infrastructure. The focus of the meeting was on the draft standard, prototype verification processes and efforts to ensure full compatibility between devices from different manufacturers.
WPC has been gradually increasing the power capacity of the Qi wireless charging standard in recent years. Offering magnetic connection support in late 2024 Qi2 The 15W version of the standard was accepted as an international standard by IEC. After this, while the transition to the 25W level was made in 2025, the consortium has now changed its target to 50W level. According to the current road map, the Qi 50W standard is planned to be completed and put into use in 2028.
Xiaomi brought the new architecture it developed to the standard draft
One of the highlights of the meeting in Beijing was the new wireless charging architecture developed by Xiaomi. According to the company, the coil design used in the current Qi2 standard brings certain hardware limitations and poses various difficulties in terms of heat management, especially in foldable phones and wireless charging units used in automobiles. For this reason, Xiaomi developed a new charging architecture with low inductance and low voltage as a result of nearly two years of work.
The company states that this approach reduces coil-related energy losses, improves heat dissipation and enables easier integration of charging modules into different devices. Xiaomi submitted the design in question to WPC in late 2024. Compatibility tests were carried out on both 25W and 50W prototypes with different manufacturers throughout 2025. Following these studies, WPC officially included the architecture developed in the first quarter of 2026 in the drafting process of the Qi 50W standard.
The four-day conference organized plugfest More than 20 companies came together at the event. Plugfest refers to comprehensive compliance tests organized to verify the applicability of industry-wide standards. In this process, chips, coils and prototype devices from different manufacturers are tested together to try to detect possible incompatibilities. Companies such as Anker, NXP and Southchip also included the hardware they developed in these tests, aiming to ensure that future 50W wireless chargers work safely with different brands and models.
Wireless charging technologies continue to improve in recent years, not only in terms of power levels but also in terms of the spread of common standards between different manufacturers. The standardization of magnetic alignment support with Qi2 allowed Android manufacturers to more easily adopt solutions similar to Apple’s MagSafe approach. While the Qi 50W standard offers higher power transfer safely, it will also bring new technical requirements in critical areas such as efficiency and temperature control.
For China-based hardware manufacturers, the inclusion of low inductance charging architecture in the global Qi standard is of particular importance. Thus, it will be possible to use components developed in local supply chains with the same standards in international markets. This approach could contribute to broader compatibility across the global device ecosystem, while reducing the need for manufacturers to develop separate wireless charging solutions for different regions. The final technical specifications of the Qi 50W standard are expected to become clear gradually over the next two years.
