Charging will be supported in two forms. The first is Qi 2.0 Charging. When attached to a supporting charger, you can get up to 25 watts for charging. This is good if you don’t want to physically plug in the charger. There will also be support for magnetic connection for charging without any special adapters. This is the Qi 2.0 standard. Putting the phone in a horizonatal layout while on a charging stand will show the the time, and any silenced notifications for when you look at the phone in the middle of the night. You would also see your next alarm, and the percentage of charge.
In addition to Qi charging, you would also have 45 watt charging for direct plug into the USB-C port at the bottom of the phone. This will give you a quicker charging method, and allow for higher charging capacity than you would receive in Qi charging.
