Instructions for iPhone 7 Battery Replacement


Step One: Preparation

  1. Keep your iPhone 7 away from any liquid during the repair as the waterproof seal will be compromised until after the repair
  2. Discharge battery to under 25%


Step Two: Open It Up

  1. Remove the two 3.4 mm screws located at the bottom of the phone
  2. Place iOpener in the center of the microwave for 30 seconds
  3. Apply the iOpener to a long edge of your iPhone 7 for approximately 2 minutes
  4. Once the adhesive is softened, apply suction cup on lower half of the front of your iPhone 7 (avoiding the home button)
  5. Pull on the suction cup until a slight gap appears in between the front and back of the phone
  6. Insert the flat end of a spudger and twist to widen the opening
  7. Slide the spudger along the sides of the phone, starting at the lower left and towards the volume buttons
  8. Remove the spudger and slide from the lower right towards the top corner
  9. Pull up on suction cup and open, raising it no more than 10 degrees
  10. Remove suction cup
  11. Slide opening pick underneath the screen on the top edge of the phone
  12. Slightly lift the screen away from the top of the phone
  13. Slide the iPhone 7 screen to the left like a book to open it up
  14. Remove the three tri-point Y000 screws

Don’t pry the two pieces apart as there are small clips that can break.


Step Three: Start the Repair

  1. Remove the lower connector bracket
  2. Use spudger to lift battery connector out of its socket
  3. Slightly bend the connector cable to prevent it from powering up your iPhone while you repair your iPhone 7
  4. Use the flat end of the spudger to disconnect the two lower display connections on the logic board
    • To re-attach, all you have to do it press down on one end until it clicks, then the other end – never the middle
  5. Remove the two 1.3 mm Phillips screws on the bracket over the front panel sensor 
  6. Remove bracket
  7. Disconnect the front panel sensor from its socket on the logic board
    • Reattach by pressing on one end at a time
  8. Remove the display assembly
    • Reapply adhesive around the edges when putting back on
  9. Remove the two 1.9 mm Phillips screws on the barometric vent
  10. Remove the vent
  11. Using the flat end of a spudger, disconnect the Taptic Engine connect from its socket
  12. Remove 1.6 mm Phillips screws (should be three)
  13. Remove the Taptic Engine
  14. Using tweezer, peel back the adhesive strips located on the lower bottom of the battery at a 60 degree angle until it slips out
  15. Hold down on the battery when pulling the second strip


If adhesive strips broke underneath the battery, you’ll need to use your iOpener on the battery for 60 seconds to reheat the adhesive. Then, use a plastic card to pry it up from the left side of the phone.


Step Four: Start the Replacement

  1. Remove the battery
  2. Place in new iPhone 7 battery with new adhesive strips
  3. Go through steps in reverse to put phone back together
  4. Perform a force restart
