Seems with the beta version 1 there are some issues with phone charging. sometime even though phone is put to charge it remains at same % even after 15-20 minutes.
I had purchased Samsung S22 Ultra last month. The battery backup is not upto the mark. Charging with 45w charger is talking 1.5 hour to charge. When remaining battery goes under 10% then it drains to 0% almost immediately, like in 2-3 minutes.
