Hello, the Apple XS wireless charging full time depends on a variety of factors, including the power of the charger, battery capacity and usage. In general, using a standard 5W wireless charger, the Apple XS takes about 3-4 hours to fully charge, while using a higher power charger (such as 7.5W or 10W) can shorten the charging time. However, if you use your phone during the charging process or turn on some power-consuming functions (such as using GPS or gaming), the charging time may be extended.
This depends on whether your charger is 18W fast charge, if it is not 2 hours
