hello sir i have bhought a new i phone 14pro max but in an accident it has been damaged can i know will it be done repaired by the warranty or should i pay any money for that

warranty by definition only really covered production defects discovered after purchase, not accident, theft or loss

Legal - Hardware Warranties - Apple

if you have purchased apple care+ then read AppleCare Products - iPhone - Apple

otherwise you should reach out to whatever other insurance companies you have policies with

Accidental events are not covered by warranty, sorry, unless you have subscribed to an Apple Care Plus Protection Plan within 60 days from the date of purchase.

Regards

Giulio
