Introduction
The guide is also useful if you want to replace the audio jack and/or charging port, since they are both soldered to the daughterboard.
For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
What you need
Step 1
Heat the bottom edge
- Completely power off your phone before you begin.
- Heat an iOpener, then apply it along the bottom 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 because the display and internal battery are both susceptible to heat damage.

Step 2
Separate the bottom adhesive
- Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible.

- Depending on the age of your phone, this may be difficult. If you’re having trouble, apply more heat to the edge and try again.
- Insert an opening pick into the gap.
