Overview
Bluetooth on an iPhone handles everything from wireless headphones and car audio to Apple Watch connectivity and AirDrop file sharing. When Bluetooth stops working, it disrupts multiple aspects of daily use simultaneously. Like Wi-Fi, Bluetooth problems sit on a spectrum from software glitches to hardware chip failure — and a greyed-out Bluetooth toggle is a reliable indicator that the latter is the case.
Common Causes
- Damage to the combined Wi-Fi/Bluetooth chip on the logic board from a drop or water exposure
- Corrupted Bluetooth pairing database causing conflicts with previously connected devices
- iOS software bug affecting Bluetooth stack operation after an update
- Disconnected or damaged Bluetooth antenna cable inside the iPhone housing
- Overheating causing solder joint failure on the Bluetooth IC over time
- Network settings corruption following a failed iOS restoration
Signs & Symptoms
- Bluetooth toggle is permanently greyed out in Control Centre and Settings
- Bluetooth enables but no devices are detected despite being in range
- Previously paired devices (car, headphones, Apple Watch) cannot reconnect
- Bluetooth connects briefly then drops repeatedly within seconds
- Wi-Fi and Bluetooth both stopped working simultaneously — a strong indicator of chip failure
Should You Try DIY?
Attempting to repair iPhone Bluetooth hardware without proper tools and training can cause permanent damage. The Wi-Fi/Bluetooth chip requires micro-soldering to repair or replace and cannot be addressed with standard tools. Always consult a professional technician.
Professional Solution
iTech Repairs technicians first attempt software-level fixes — network resets, iOS updates, and pairing database clears — before assessing the Bluetooth/Wi-Fi IC hardware. Where hardware repair is necessary, our technicians use micro-soldering equipment to address chip and antenna faults. Every repair is tested with multiple Bluetooth devices before the iPhone is returned.

Frequently Asked Questions
- Why is my iPhone Bluetooth not working?
- Bluetooth failures range from a simple pairing conflict — resolved by forgetting the device and re-pairing — to a hardware fault where the Wi-Fi/Bluetooth chip has been damaged by a drop or water.
- Why is the Bluetooth option greyed out on my iPhone?
- A greyed-out Bluetooth toggle means the Bluetooth hardware has failed. The Wi-Fi and Bluetooth share a single chip on iPhones; damage to that chip disables both. This requires a board-level repair.
