The detection method is:
Connect the iPhone to Ace Assistant via WiFi to check the real-time charging power. If the battery is below 50%, the iPhone will keep full speed fast charging, and the original charger can reach 18W. At this time, Ace Assistant will show \"Fast charging (18W)\".
< br >
When the battery power increases to 50% ~ 80%, the iPhone will automatically adjust the charging power to 12-15W, and the charging power displayed will also change accordingly.
< br >
If the power number displayed during charging is not up to standard or does not change with the current power, there is a problem with the adapter.
