Why is wireless charging slower for my iPhone on my Xiaomi SU7 compared to other phones?
The Xiaomi SU7 comes standard with a mobile phone wireless charging pad with a maximum charging power of 50W, but the actual charging power varies depending on the phone brand/model and the phone's status:
The Xiaomi SU7's mobile phone wireless charging pad supports Xiaomi's private protocol and the Qi protocol, resulting in different wireless charging powers for different phones.
Xiaomi series phones use Xiaomi's private protocol for wireless charging, allowing them to achieve a maximum charging power of 50W on the Xiaomi SU7's mobile phone wireless charging pad. However, the Xiaomi 13 Pro uses a low-inductance receiver coil with low heat generation and high efficiency, so it can achieve a maximum wireless charging power of 30W on the Xiaomi SU7's mobile phone wireless charging pad.
Other Android phones use the Qi protocol for wireless charging, so they can achieve a maximum wireless charging power of 15W on the Xiaomi SU7's mobile phone wireless charging pad.
Because Apple phones use specific frequency bands of the Qi protocol, they can achieve a maximum wireless charging power of 7.5W on the Xiaomi SU7's mobile phone wireless charging pad.
Additionally, the wireless charging power varies depending on the phone's status.
If the phone is currently in a high-power operation state, the wireless charging power will actively decrease for thermal protection.
If the phone's current battery level is relatively full, the wireless charging power will also actively decrease for battery protection.
If the phone is placed off-center, it may also lead to reduced wireless charging power. You can try adjusting the phone's position to obtain the maximum wireless charging power.
