What you need

  1. Battery Disconnection, Prepare your phone for disassembly: step 1, image 1 of 2 Battery Disconnection, Prepare your phone for disassembly: step 1, image 2 of 2

    • Let your phone's battery drain below 25% before starting this repair. A charged lithium-ion battery may catch fire if accidentally damaged.

    • Completely power off your phone and unplug all cables.

    Edit

  2. Battery Disconnection, Heat the bottom edge: step 2, image 1 of 1

    • Mild adhesive secures the back cover. Heating it will soften the adhesive, making it easier to separate.

    • Heat an iOpener and lay it on the bottom edge of the back cover for two minutes to soften the adhesive.

    • Alternatively, you can use a hair dryer, heat gun, or hot plate to heat the cover.

  3. Battery Disconnection, Apply a suction handle: step 3, image 1 of 2 Battery Disconnection, Apply a suction handle: step 3, image 2 of 2

    • Apply a suction handle near the center of the back cover's bottom edge, as close to the edge as possible.

    • The back cover is secured with adhesive around the perimeter of the frame. Use this picture as a reference while you separate the adhesive.

    • When separating the left and right edge adhesive, don't insert your pick more than 3 mm to avoid damaging the wireless charging coil and interconnect cable.

    • Continue sliding your pick around the entire perimeter of the back cover to separate all the remaining adhesive.

    • Remember not to insert your pick too far under the long left and right edges.

    Edit

  9. Battery Disconnection, Remove the back cover: step 8, image 1 of 2 Battery Disconnection, Remove the back cover: step 8, image 2 of 2

    • Remove the back cover.

    • If you're having trouble, check the perimeter for any remaining adhesive and use your opening pick to separate it.

    • During reassembly:

    • This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

    • Check your rear cameras for any smudges and gently wipe them with a clean lint–free cloth if necessary.

    • Your replacement back cover adhesive will be applied to either the frame or the back cover. Use cutouts and contours to see where it lines up best. If it matches the back cover, follow this guide. If it matches the frame, use this guide.

  10. Battery Disconnection, Disconnect the wireless charging assembly: step 9, image 1 of 2 Battery Disconnection, Disconnect the wireless charging assembly: step 9, image 2 of 2

    • Use the point of a spudger to pry up and disconnect the wireless charging assembly press connector from its top edge.

    • Getting the spudger under the connector can be tricky. If you're having trouble, try using the tip of an opening pick instead.

    • The wireless charging coil is connected to the loudspeaker with delicate tape. It's easiest to remove the coil and loudspeaker together as one assembly to avoid damage.

    • Use angled tweezers to pry up and unclip the loudspeaker by the notch on its left edge.

    • During reassembly, press down firmly around the perimeter of the loudspeaker to engage its clips.

    • Every press connector has a corresponding gold arrow on the board that shows the proper location to pry—nifty! Prying at the wrong location risks damaging the fragile surface‑mounted components on the board.

    • Use the point of a spudger to pry up and disconnect the battery press connector.
