Hi Justin,<br /><br />Charging performance can vary depending on a few factors. If the device is charged using the USB-C cable, it is designed to provide a full charge for an iPhone 17 Pro Max under normal conditions. When using wireless charging, the amount of charge delivered can vary based on several factors, such as:<br /><br />The starting battery level of the phone<br /><br />Whether the phone is being used while it is charging (streaming, gaming, or running apps can significantly reduce the net charge gained)<br /><br />Background processes running on the phone during charging<br /><br />If the phone is actively being used while wirelessly charging, it’s possible for the battery level to increase slowly, stay the same, or even decrease slightly depending on the power being consumed.<br /><br />For the best results, we recommend using the USB-C wired charging option or allowing the phone to charge wirelessly while not in use.
