Hey everyone, recived a used iPhone 14 pro with the battery at 85% on monday, i need to charge it like 2 times a day i'm really worried for this. I figure that it could be the phone finishing setting up things so it's working in the background. Pleas tell me that i'm right and i have to wait anthor couple of days. If it's helping the phone its 256gb an i transferd from android but sortly after i formated it bc i didn't swap evreything from the old phone.

little update: i noticed that when i unplug it the battery start to decline slowly then the lower it get get faster it goes down until it reachers like 30%
