We quickly cleaned the speakers and the connector on the iPhone, now everything is audible as on the first day of purchase, I was already going to change the speakers, thanks for the time and money saved
It was necessary to change the battery on the iPhone 2020, They offered to leave the phone, an Apple ID with a password and a phone password. Otherwise, they refused to change the battery.
