Charging a Glass iPhone with a Metal Backplate: Is It Possible?

Have you ever considered attaching a metal backplate to your glass iPhone and still want to charge it wirelessly? While it might seem plausible, there are several challenges to overcome. This article will explore the feasibility of charging a glass iPhone with a metal backplate, and provide tips and information for enthusiasts who wish to do so.

Understanding Wireless Charging and Metal Backplates

The concept of wireless charging relies on the principle of electromagnetic induction. When a coiled transmitting circuit is activated, it creates a magnetic field. This field, in turn, induces a current in another coiled receiving circuit, which is the wireless charging coil in your smartphone. However, the presence of a metal backplate can significantly impede this process.

Effect of Metal Backplates on Wireless Charging

Many modern smartphones, including iPhones, utilize a magnetic ring called MagSafe to align the wireless charger with the phone. The ring serves to enhance charging efficiency and also allows for the attachment to magnetic phone mounts. However, if you attach a metal plate to your iPhone, this ring and the magnetic alignment will be disrupted. As a result, the magnetic field that couples the wireless charger to the coil in the phone will be blocked, preventing effective wireless charging.

Testimonials and Experiences

To better understand the impact of a metal backplate on wireless charging, consider the following testimonies:

One individual mentioned that they had successfully charged their S20 with a metal plate on the back by using a ring-style magnetic mount. They noted that the ring was centered in the back, suggesting that their S20's wireless charging coil was centrally placed and relatively small. Another person stated that they had glued a metal plate to the back of their cellphone, indicating that their device was not capable of wireless charging. In this case, since there would be a magnet embedded in the back of a wireless-charging capable device, the metal plate would interfere with the magnetic alignment required for wireless charging. A user familiar with MagSafe mentioned that this system requires careful alignment for optimal charging efficiency. However, they also mentioned that the metal plate would block the magnetic field, making wireless charging impossible.

These experiences highlight the challenges in overcoming the interference caused by the metal backplate.

Alternatives to Metal Backplates

Given the potential issues with a metal backplate, it is advisable to consider alternative solutions:

1. Removing the Metal Backplate

One straightforward approach is to remove the metal backplate entirely. This will restore the magnetic alignment needed for wireless charging and ensure your iPhone can charge efficiently.

2. Using a Cable Instead of Wireless Charging

For scenarios where wireless charging is not feasible, consider using a charging cable. This provides a reliable and uninterrupted power supply, bypassing the interference caused by the metal backplate.

3. Custom Design Solutions

For those determined to keep the metal backplate, a more advanced solution would involve a thorough understanding of the phone's design, ensuring that the wireless charging coil is correctly coupled with the magnetic circuit. This requires significant expertise and is a complex project.

Conclusion

While attaching a metal backplate to your glass iPhone is achievable, it poses significant challenges to wireless charging. The best solution is to either remove the metal backplate or use a cable for charging. However, for those willing to explore more advanced customization, a thorough understanding of the phone's design and magnetic circuits is necessary.
