iPhone X Charging Port Replacement: Full Walkthrough for Repair Shops

The iPhone X was Apple's first iPhone with a stacked logic board, and the charging port flex is routed through three layers of bracket. Get one screw wrong and you crack the board-side pads. Walk through the full repair here.

Tools you need

  • Pentalobe P2 driver for the bottom screws
  • Tri-point Y000 driver for internal brackets
  • Phillips #000 for the port bracket
  • Heating pad or hot air at 65–80 °C
  • Plastic picks, suction cup, spudger, tweezers
  • Isopropyl, fresh water-seal adhesive

Budget 50–60 minutes for the first attempt; experienced techs cut it to 30.

Step-by-step

  1. Power off, remove bottom pentalobes, heat the lower edge 2 minutes
  2. Suction-cup the bottom, lift the display, open like a book to the left (the top flex cables are short — do not pry past 90°)
  3. Disconnect the battery first
  4. Remove the display assembly completely to access the lower bracket
  5. Unclip the antenna line, unscrew the port bracket (four screws, three different lengths — lay them out on a magnet pad)
  6. Lift the old charging port flex out — note the microphone gasket, transfer it if the new flex lacks one
  7. Seat the new flex, route the antenna line back, torque the three screw sizes back in their original positions
  8. Reconnect battery last, then perform the five tests below before sealing

The five post-repair tests

  • Charge test: 0% to 80% within 30 minutes via a 20 W adapter
  • Sync test: iTunes / Finder recognition
  • Mic test: voice memo records clean audio at 30 cm
  • Speaker test: speakerphone and bottom loud speaker both play
  • Audio routing test: Siri responds when spoken to at arm's length

If any of those fail, the most common cause is the antenna line not seated in its channel — not a bad flex. Re-seat before reordering.

Common mistakes

  • Mixing the three bracket screw sizes — the board-side pads crack under wrong torque
  • Forgetting the water seal — warranty arguments in three months
  • Skipping the battery disconnect — shorting the board pads destroys the phone

The full iPhone X parts range, including port flexes and water seals, ships with per-unit QC from Shenzhen.

FAQ

iPhone X or iPhone XS charging port — same part? Footprint is the same, but connector pinouts differ subtly. Order by exact model from the charging port collection to avoid a phantom "not charging" comeback.

What MOQ for testing a new supplier's port? 10 pieces mixed is enough to evaluate connector feel and gasket quality on the bench.
