my ip 7 suddenly take longer time to boot up in d apple logo screen (4-5 mins). I cant make any related calls (phone, whatsapp etc) unless i use my airpods. Not just that, any audio input related function is toasted....but d sound output is still fine.

Is it repairable and actually worth to do so? My phone is 2.5 years old and was actually thinking to change soon....but idm keeping my ip7 as a spare.
