I am really grateful for finding a solution within these replies. [br]
Even though the problem might have been a different one, it looked like the battery was dead.
I have iPhone 13 Pro Max and this hairdryer thing worked! [br]
The battery was not even dead it was 79% charged!
A little background detail if it might help other people with similar issue:
The phone was left to charge over night close to an open window. [br]
It was raining overnight, so there is a possibility a few drops fell on the phone, although it did not look like there were. [br]
It was turned face down, so even if there were a few drops they would not have fallen on the actual phone. Outdoor temperature was about 8 celsius. [br]
In the morning the phone was dead. [br]
It was still plugged in.
I tried different chargers, wireless and wired. [br]
I tried rebooting or hard starting or whatever the word for that is.
Eventually I tried the hairdryer. [br]
It booted up after 2 minutes.
Note: I always charge the phone overnight in same place with open window and this never happened, even when it rained and even the temperatures were below zero.
