If you feel that Tesla wireless phone charging is too slow, there may be several reasons:
1. Insufficient power output: Tesla wireless phone chargers need to be connected to a power source to provide charging. If the power output is insufficient, the charging speed will be slow.
2. Mobile phones do not support wireless fast charge: Some mobile phones support wireless fast charge technology, which can charge faster. If your phone does not support wireless fast charging, the charging speed will be slow.
3. Other interference: Wireless charging requires a certain distance between the charger and the phone, and if there is interference from other electronic devices or metal objects, it may also lead to slower charging.
If you are not satisfied with the charging speed, you can try to change the power supply or location, as well as check whether the phone supports wireless fast charge technology.
It could be because the battery is faulty
