The impact of wireless charging on mobile phones mainly depends on the quality of the charger and the charging protocol of the mobile phone. First of all, if the wireless charger is a legitimate brand and matches the charging protocol of the phone, then it usually does not cause significant damage to the phone. However, if the charger has quality problems or does not match the charging protocol of the phone, it may cause damage or overheating of the phone battery. Second, if the phone supports a wireless charging protocol, it will usually be charged as needed. If the phone is fully charged, or the wireless charger is turned off, the phone will automatically stop charging. Therefore, in this case, charging all the time will not cause additional damage to the phone. However, it should be noted that if the phone overheats or has other abnormal conditions while charging, it should immediately stop charging and contact the manufacturer or after-sales service center for repair or consultation. In addition, for some special types of phones, such as those with removable batteries, the use of wireless chargers may be limited or not applicable to the device. In short, if the car wireless charger is a formal brand, matches the charging protocol of the mobile phone, and the mobile phone supports the wireless charging protocol, then the charging of the mobile phone usually does not cause significant damage. However, in order to ensure safety and extend battery life, it is recommended to turn off the wireless charger when it is not needed to charge.
