    • For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

    • Unplug any chargers/peripheries and power off your phone.

    • Use a hair dryer to lightly heat the perimeter of the rear glass.

    • Additionally, heat the top-right corner, as there is adhesive further inside of phone in that one spot.

    • Do not hold the hair dryer in one spot on the phone for too long to prevent damage to internal parts of the phone.

    • Apply a suction handle as close to the bottom edge as possible.

    • Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.

    • If you have trouble creating a gap, apply more heat to further soften the adhesive.

    • Insert an opening pick into the gap.

    • Slide the opening pick around the perimeter of the rear glass to slice the adhesive.

    • Insert additional opening picks as you slice the adhesive to prevent the adhesive from resealing.

    • If the adhesive becomes hard to cut, it has most likely cooled down. Use your hair dryer to reheat it.

    • Carefully lift the rear glass up and off of the phone.

    • During reassembly secure the rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

    • Take care not to bend or puncture battery during the removal procedure—a bent battery may leak dangerous chemicals or cause a fire.

    • Remove the battery from the phone by slowly pulling up on the red tabs.

    • If you're having trouble lifting the battery out of its recess, apply a heated iOpener to the screen side for two minutes to loosen the battery adhesive.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.
