Hello, there may be several reasons for the slow wireless charging speed of Tesla mobile phones:
1. Lack of charger power: Tesla mobile phone wireless charging needs to match the Tesla brand charger, if the use of lower power charger, charging speed will be slow.
2. Wrong charger position: The charger must be aligned with the phone's charging coil, otherwise the charging effect will be reduced.
3. There are obstacles between the charger and the phone: if there are obstacles between the charger and the phone, such as metal plates, magnets, etc., it will affect the effect of wireless charging.
4. The phone heat is too high: If the phone overheats, wireless charging will automatically reduce the power to protect the battery, resulting in slower charging.
5. Other factors: the limitations of wireless charging technology itself may also lead to slower charging speed.
