Transferring iPhone se to iPhone 13 mini

I got a new iPhone 13 mini and I am trying to transfer from my iPhone se it has been 16 hrs the new phone seems to be updated from my old phone, but my old phone says Transferring Data to iPhone

keep your other iPhone nearby and connected to power until the transfer is complete ( time remaining About 1 minute) this is on a locked screen. When will I know it’s done?
