Allow your phone's battery to drain below 25%, as a charged lithium-ion battery is a potential safety hazard. If your battery is swollen, take appropriate precautions.
Unplug any cables from your phone.
Hold the side key and the volume down button, then select "Power off" to turn off your phone.

Step 2 Heat the right edge

Heat an iOpener and apply it to the right edge of the back cover for two minutes.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are susceptible to heat damage.

Apply a suction handle to the back cover, as close to the center of the right edge as possible.
Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Insert an opening pick into the gap.

Step 15 Remove the back cover

Grab and remove the back cover.
If the back cover is not lifting easily, use an opening pick to separate any adhesive that may have resealed.
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.
Retaining water resistance after the repair will depend on how well you reapply the back cover adhesive, but your device will lose its IP (Ingress Protection) rating.
Use tweezers or your fingers to remove all adhesive from the back cover and the phone. Use heat or isopropyl alcohol (90% or greater) and a coffee filter or lint-free cloth if you're having trouble removing the adhesive.
If you're using custom-cut adhesives, follow this guide.

Use a spudger to pry up and disconnect the wireless charging coil press connector from the motherboard.
There's an arrow printed on the board near each press connector that indicates the recommended prying location.
To reconnect press connectors, align the connector carefully over its socket and press down with your fingertip—first on one side, then the other—until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.
