When choosing a phone case for the iPhone 15, wireless charging compatibility is a key concern for many users. The iPhone 15 series supports MagSafe wireless charging and Qi standard wireless charging. Whether the phone case will affect this convenient function depends on a variety of factors.

　　Material affects compatibility: The impact of iPhone 15 phone cases made of different materials on wireless charging varies significantly. Plastic and silicone materials usually do not impede wireless charging because they lack conductivity and do not interfere with the transmission of charging signals. Like the common silicone soft shell and transparent plastic hard shell, they can ensure the protective function while allowing wireless charging to proceed smoothly. But metal phone cases are the "archenemy" of wireless charging. Metals are conductive and can interfere with the magnetic field of wireless charging, causing a significant drop in charging efficiency or even making it impossible to charge. If the metal phone case has a built-in magnetic attraction function, although it can be attached to the MagSafe charger, the charging power may still be limited due to the interference of the metal to the magnetic field. Therefore, if you value the wireless charging function, you should try to avoid phone cases made of metal materials.

　　The design structure is different: The design structure of the phone case is also closely related to the compatibility of wireless charging. Some phone cases are designed with the need for wireless charging in mind, reserving a charging area or using special techniques to make the charging area more in line with the wireless charger, reducing charging obstacles. For instance, some phone cases adopt an ultra-thin design in the wireless charging area on the back to ensure that the charging signal is not overly blocked and can maintain a good charging efficiency. Conversely, if the phone case is too thick, especially in the wireless charging area, it will increase the distance between the charging coil and the charger, weaken the magnetic field strength, and reduce the charging efficiency. Some phone cases with complex designs, such as those with multi-layer structures, excessive decorations or special functions (such as built-in stands and located close to the charging area), may also interfere with wireless charging. Extra caution is needed when making a purchase.

　　Whether it supports MagSafe: For the MagSafe wireless charging function of the iPhone 15, not all phone cases can be perfectly adapted. MagSafe technology achieves fast and efficient charging through precise magnetic positioning, with a maximum power of up to 15W. If the phone case is equipped with magnets compatible with MagSafe and their arrangement and performance meet the standards, it can be closely attached to the MagSafe charger and charge efficiently. The Magsafe protective case officially launched by Apple has a built-in magnet that precisely aligns with the iPhone 15 series. It is easy to install and enables quick wireless charging without the need to remove it during charging. Some magnetic phone cases of third-party brands, by obtaining the Apple MFi (Made for iPhone) certification, can also ensure compatibility with MagSafe and achieve stable and efficient wireless charging. However, uncertified or poorly designed magnetic phone cases may have problems such as insufficient suction and inability to align precisely, which can affect the charging effect and even lead to unstable charging and severe overheating.
