On December 29,2018, I applied to Apple service for a replacement battery under warranty. After a full and long waiting period, the battery of my phone was changed and delivered.
However, when I got the phone, the touch ID didn't work, and the phone reactions were slow. When I showed my phone to the authorities again, they said that they had to adapt for a while and then handed the phone over. However, although I did not charge the phone with the original charger, the phone did not charge and did not turn on.
The next morning on December 30 I brought my phone back to the same service, and I reported the situation to the authorities. However, they said my phone should be serviced and that there could be a repair period of 20 working days.
