Xiaomi SU7's phone wireless charging supports up to 50W, so why does it sometimes feel slower?
The Xiaomi SU7 comes standard with a phone wireless charging pad with a maximum charging power of 50W, but the actual phone charging power may vary due to differences in phone brand/model and phone status:
The phone wireless charging pad in the Xiaomi SU7 supports Xiaomi's proprietary protocol and the Qi protocol, resulting in different wireless charging powers for different phones.
For Xiaomi series phones, wireless charging uses Xiaomi's proprietary protocol, allowing them to achieve a maximum charging power of 50W on the Xiaomi SU7's phone wireless charging pad. However, the Xiaomi 13 Pro, which uses a receiving coil with low heat generation and high efficiency (small inductance value), can achieve a maximum wireless charging power of 30W on the Xiaomi SU7's phone wireless charging pad.
Other Android phones use the Qi protocol, so they can achieve a maximum wireless charging power of 15W on the Xiaomi SU7's phone wireless charging pad.
Since 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 phone wireless charging pad.
Different phone statuses also result in different wireless charging powers.
If the phone is currently in a high-power operating state, its wireless charging power will be actively reduced for thermal protection.
If the phone's current battery level is relatively full, its wireless charging power will also be actively reduced for battery protection.
Additionally, 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 achieve the maximum wireless charging power.
