Iphone 7 Plus Charging Flex

What the charging flex cable includes

• Charging port: The Lightning connector at the bottom of the phone.
• Microphone: The lower microphone used for speakerphone calls.
• Cellular antenna: Connectors for the phone’s antenna.
• Headphone port function: Since the iPhone 7 series removed the 3.5mm jack, this part also manages the audio functionality that goes through the Lightning port. 

Symptoms of a faulty charging flex

• Failure to charge: Your phone does not charge when connected, or the connection is intermittent.
• Charging issues: Your phone charges very slowly or loses charge quickly.
• Microphone problems: People can’t hear you during calls, especially on speakerphone.
• Connectivity issues: The phone doesn’t sync data or recognize accessories when plugged in.

Professional vs. DIY repair

• For professional repair: Take your device to an authorized Apple service provider or a third-party repair shop. The repair cost can vary but is often between $60 and $100 for older iPhones.
• For DIY repair: For those with experience, sites like iFixit offer detailed step-by-step guides. You will need specialized tools like a pentalobe screwdriver and caution is advised, as improper installation can cause further damage. Keep in mind that opening your phone will compromise its waterproof seals, which should be replaced if you want to maintain water resistance.
