1. Slow wireless charging speed makes users indulge in uncertain waiting

"Wireless charging" sounds like a bright future, but the reality is often so "slow". Although Apple claims that its 7.5W wireless charging technology meets the new industry norms, the speed has not been significantly improved compared to the previous generation of iPhones. This makes people wonder: "Why do we have to spend extra time waiting for charging?" Especially compared with faster wired charging solutions, this slow speed has become an obstacle to the user's "experience".

2. Slow charging hinders the development of wireless charging

Even at 7.5W, the wireless charging process for an iPhone still takes about five hours to fully charge. This time means that users may be trapped in the "charging anxiety" of their phones while waiting. This is not only a user experience issue, but also a huge obstacle.

3. Openness and standardization are the key to the future of wireless charging technology

Although wireless charging speed and efficiency face challenges, there are still good reasons to believe that it will make progress. The article believes that improving charging efficiency is the key to achieving a more impactful user experience.

• Power Optimization: While pursuing higher power levels, like potential 1000W wireless charging, could drastically reduce charging times, this might not be entirely practical given how current technology works.
• Open Standards: The importance of open wireless charging protocols such as Qi2 for widespread adoption and convenience. Lack of standardization has hampered progress toward faster and safer wireless charging.

4. From electromagnetic induction to a higher future

Wireless charging technology faces new challenges during its development.

• Power peaks and safety: Currently, most wireless charging solutions rely on traditional electromagnetic induction technology, which has its limitations in terms of power output and safety issues. These limitations are particularly prominent when pursuing high power levels.
• Infrastructure and Accessibility: Integrating wireless charging into everyday objects such as restaurant tables, train seats and cars has revolutionary potential. This could completely change the user experience but depends on developing reliable infrastructure and standardized protocols.

5. In the future, wireless charging will become an ideal alternative

From speed to safety to the future, the future of wireless charging technology is full of hope. I believe that through multi-faceted efforts, wireless charging technology will have more opportunities to become popular and bring users a more convenient experience.

Attachment:

• Apple's wireless charging stalemate: Although Apple claims that its 7.5W wireless charging technology meets the new industry standard, it has not been significantly improved compared with the previous generation of iPhones. This slow speed has become a focus of controversy.
• The dual challenges of user experience and efficiencyEven at 7.5W, the wireless charging process for an iPhone still takes about five hours to fully charge. This slow charging further widens the gap between Apple and Android devices in terms of performance and user experience.
• The future of wireless charging protocols: The importance of open protocols such as Qi2 for widespread adoption and convenience. Lack of standardization has hampered progress toward faster, safer wireless charging.
