The original 5 watt Qi was good for overnight charging. USB-PD quick charging can yield charging in 20 minutes for 50%, full charge in an hour. Qi EPP can yield 15 watt charge with appropriate devices, which is close enough to wired USB-PD useful for top-off day charging. Using the manufacturer recommended charger (typically USB-PD) to power the wireless charger is vital to meet full power specs.
The closer the phone (thinner the case) and better aligned the phone is, the faster and cooler it will charge. If the device is getting too hot, it will backoff the charge rate to maintain appropriate temperature. The thermal insulating effect of the phone case retains extra heat from charging.
Be aware that some stands like the Pixel Stand 2 do not allow for sideways (landscape) device orientation while charging.
