Use this guide to replace the electronic portion of power button and the attached ambient light/proximity sensors.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Your phone's rear cover may have two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws. Check which screws you have, and ensure you also have the correct screwdriver in order to remove them.

    • Remove the two 3.6 mm Pentalobe or Phillips #000 screws next to the dock connector.

    • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.

  2. Push the rear panel toward the top edge of the iPhone. The panel will move about 2 mm.
    • Push the rear panel toward the top edge of the iPhone.

    • The panel will move about 2 mm.

  3. Pinch the rear panel with your fingers, and lift it away from the iPhone. Alternatively, use a Small Suction Cup .
    • Pinch the rear panel with your fingers, and lift it away from the iPhone. Alternatively, use a Small Suction Cup .

    • Be careful not to damage the plastic clips attached to the rear panel.

  4. Remove the single 1.5 mm Phillips screw securing the battery connector to the logic board (if present).
    • Remove the single 1.5 mm Phillips screw securing the battery connector to the logic board (if present).

    • Remove the metal clip covering the antenna connector.

  6. Pull up on the exposed clear plastic tab to peel the battery off the adhesive securing it to the iPhone. If the tab breaks before the battery is freed, carefully slide a spudger under the battery tab to release the adhesive. Prying in other places may cause damage.

This one was a bit difficult with the routing of the cable, but overall easy for a first timer.

My power button quit working. I bought the cable assembly and replaced it per these instructions. Everything seemed to work at first but later I noticed my phone kept trying to shut itself off. Any ideas what is causing this? It only seems to occur after I use the power button. It is almost as if it is getting stuck down.

Please remove your screen first, before replacing power button or sensor cable. I advise you to not dare attempt to remove those Step 25 screws (power button cable bracket ) while screen is mounted.

It is too risky! Display's ribbon cable interferes with driver access to these screws. While driving these screws, I unknowingly broke my display cable. It is actually a delicate circuit, not just a simple flexible ribbon. If I knew just how delicate is display cable, then I would not have ventured to perform this replacement. (In my case, only proximity sensor was not working; power and and ambient light sensor were both functioning. In my case, it was not worth breaking a pricy screen for sake of a cheap sensor.)

With a broken screen cable, iPhone endlessly repeats a diagnostic sound or vibration.
