45 minutes - 1 hour
When my daughter called people they could not hear her but she could here them.
The repair went well but the parts I ordered did not solve the problem. The solution was to take the logic board out and take the chip plate off and put a very small square (cut from credit card) over the chip. The phone work perfect after that. It was an IPhone flaw.
If you have the same problem with the IPhone ck the the chip before ordering parts. But due the age of the phone it did not hurt to change The particular parts. The docking port and antenna.
