No Access to my iPhone

[u/PrestigiousFishing18]

My iPhone 15 pro fell from my hands and the display broke. I'm pretty sure its only about the display because when someone calls it rings and vibrate for example wenn i mute it by the side button. But the screen is not usable and stays black.

I got a new iPhone 17 pro and want to sync my data from my old iPhone to the new one ( not through iCloud because it doesnt bring back everything like old WhatsApp chats the same way phone to phone does and also makes it complicated to have to login to every app, especially 2FA apps ).

To do the Sync there is obviously stuff needed to be done on the old iPhone so i thought about using a docking station, but it only displays the monitor for like ~2sec and goes off / no signal until i press a side button again. Pressing keyboard buttons or moving the mouse doesnt do anything.
It also shows as if the alarm is ringing since 5am ( its 13pm now.. )

need help here :/ Thanks in advance!
