Summary

Replace the battery in iPhone 15 Pro when it no longer holds adequate charge or device performance degrades. Batteries are rated for 1000 charge cycles at 80% capacity. This procedure requires opening the device, disconnecting cables, and removing the old battery. Replacement screen adhesive and battery adhesive (if not pre-installed) are required.

Procedure

  1. Drain battery below 25% to prevent fire risk from damaged lithium-ion cells
  2. Power off the device completely
  3. Unplug all cables
  4. Tape over any cracked screen or back glass to protect against injury and ease disassembly
  5. Mark opening picks 3 mm from tip using permanent marker to prevent over-insertion damage
  6. Remove two 7 mm pentalobe screws on either side of charging port using P2 screwdriver
  7. Heat bottom edge with hair dryer or heat gun until hot to touch
  8. Apply suction handle to bottom edge and pull with steady force to create gap
  9. Insert opening pick into gap; slide along bottom edge (max 3 mm depth) to separate adhesive
  10. Heat right edge until hot to touch
  11. Insert pick (max 5 mm depth) around bottom right corner toward power button until feeling hard stop at clip
  12. Rotate pick flat-edge under screen and twist to release right clip
  13. Insert second pick and slide both picks to separate right edge adhesive (max 5 mm depth)
  14. Heat top edge until hot to touch
  15. Separate top edge adhesive with pick (max 3 mm depth) to release two clips
  16. Heat left edge until hot to touch
  17. Separate left edge adhesive with pick (max 2 mm depth) to avoid two screen cables; rotate around top left corner to bottom left
  18. Prop up screen using small box or books; swing up right edge like book cover
  19. Remove six Y000 screws from logic board cover (four 1.6 mm, two 1.3 mm screws)
  20. Rotate logic board cover counterclockwise at bottom; slide top left corner out from under ambient light sensor cable
  21. Disconnect battery press connector from bottom right of logic board using opening pick
  22. Disconnect screen cable from center of logic board
  23. Disconnect ambient light sensor cable from top left corner
  24. Remove screen

Notes

  • Safety: Do not heat phone above hot-to-touch temperature; battery is heat-sensitive
  • Cable locations: Two delicate screen cables are located just above the action button and near middle of left edge
  • Spring contacts: Multiple spring contacts around phone perimeter; do not over-insert picks in these areas
  • Parts pairing: iOS 17.6 and earlier may show replacement part warnings and disable battery health data; iOS 18+ supports calibration via Repair Assistant with authentic Apple batteries
  • Swollen batteries: Take appropriate precautions if battery is visibly swollen
  • Pick depth limits: Bottom edge (3 mm), right edge (5 mm), top edge (3 mm), left edge (2 mm)
  • Reconnection: Press connectors click into place when aligned; ensure flat seating as insulating rubber may prevent full connection appearance
  • Reassembly: Ensure logic board cover top left corner goes under ambient light sensor cable during reinstallation
