Overview
What this part is
The side (power) button on the iPhone 15 presses against a small switch on a flex cable inside the frame. The supplier lists this flex as the power button and Bluetooth flex, so it also carries an antenna section. A drop or liquid damage can leave the side button dead or unreliable.
This part replaces that flex. The volume buttons use a separate flex. If the button feels stuck or loose, the fault may be the metal button cap rather than the flex.

Professional installation
How a technician fits this part
- Power the iPhone 15 off, remove the two pentalobe screws beside the charging port and warm the edges to soften the adhesive.
- Open the phone carefully and disconnect the battery before anything else.
- Remove the parts covering the button flex and peel the old flex carefully away from the frame.
- Fit the new flex, line up each switch with its button and seat the connector firmly.
- Reconnect the battery, then test the repair before sealing.
- Apply new adhesive, close the phone and press evenly while it cures.
- Test the side button: lock, wake, Siri and power off.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my iPhone 15?
Yes, if Settings › General › About shows iPhone 15. It fits models A3090, A2846, A3089 and A3092. It does not fit the iPhone 15 Plus or iPhone 15 Pro.
Does it fit the iPhone 15 Plus?
No. The iPhone 15 Plus uses a different part. This one is made only for the iPhone 15.
Does this part fix the volume buttons?
No. On the iPhone 15 the volume buttons use a separate flex. This part covers the side (power) button.
Is it made by Apple?
No. It is a brand new, OEM-quality power button and bluetooth flex cable made to fit the iPhone 15, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. Opening an iPhone needs heat, pentalobe and tri-point screwdrivers and new adhesive, and the battery must be disconnected safely.
