Introduction

This guide shows the procedure on the cellular/LTE version of the watch, but the GPS-only version is similar.

Note: The battery replacement procedure for the 40 mm Series 6 Apple Watch differs slightly from the 44 mm version. This guide shows how to replace the battery for both sizes.

Before you begin, make sure you have the appropriate replacement battery for your watch.

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

You’ll need replacement adhesive to reattach components when reassembling the device.

What you need

Step 1

              Power down the watch
  • Before starting repairs, take your watch off the charger and power it down.
  • If your touchscreen is broken and you can’t power off the watch, use this alternate method to power it down.

Step 2

              Safety Requirements
  • Because the gap between the screen and watch body is so thin, a sharp blade is needed to separate the two. Read the following warnings carefully before proceeding.
  • Protect your fingers by keeping them completely clear of the knife. If in doubt, protect your free hand with a heavy glove, such as a leather shop glove or gardening glove.
  • Be careful not to apply too much pressure, as this might cause the knife to slip and cut you, or damage the watch.
  • Wear eye protection. The knife or glass may break, sending pieces flying.
  • Attach or remove the watch band as needed to provide more control as you make repairs.

Step 3

              Soften the display adhesive
  • Prepare an iOpener (or use a hair dryer or heat gun) and heat the face of the watch to loosen the display adhesive.
  • Leave the iOpener on the watch for at least two minutes to fully heat the screen and soften the adhesive holding it to the case.
  • You may need to reheat the iOpener and repeat this procedure several times until the display adhesive softens.

Step 4

              Display opening
  • Place the edge of a curved blade into the thin gap between the display and the outer case. Start at the short side of the display, most distant to the digital crown.
  • Press firmly straight down into the gap.
  • Once inserted, tilt the blade to pry the display open slightly.

Step 8

  • Place the watch on a flat surface and use an opening pick to slice through any remaining adhesive.
  • Try not to slice near the watch crown to prevent damaging the display cables. If you must slice near the crown, don’t insert the opening pick deeper than 1/16th of an inch (~2 mm).
  • Slide an opening pick under the opposite display edge of the watch crown.
  • Twist the opening pick to loosen the display off the watch case.
  • Don’t try to remove the display. It is still connected to the watch assembly.

Step 11

              Determine which procedure to follow
  • From this point, the battery removal procedure for the 40 mm watch differs slightly from the 44 mm version.
  • If you’re replacing the battery for a 40 mm watch, continue with this step.
  • If you’re replacing the battery for a 44 mm watch, continue with this step.

Step 12

              Pry up the battery
  • The following four steps show how to remove the battery from a 40 mm Apple Watch Series 6.
  • Insert an opening pick between the battery and the Taptic Engine.
  • Use constant, steady pressure to slowly pry the battery up, separating it from the adhesive securing it to the mainboard.
  • Make sure you don’t puncture or deform the battery, as it can catch fire and/or explode if damaged.
  • Don’t try to remove the battery all the way yet. It is still connected to the watch assembly.

If you are reusing your old battery during reassembly, you can reuse the existing adhesive to secure the battery during reassembly.

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your Apple Watch Series 6, follow these instructions in reverse order. Apply a little bit of high isopropyl alcohol (>90%) to a Q-tip or use a cleaning pad to gently remove the leftover adhesive on the edges of the watch case and the screen before installing new adhesive.

For optimal performance, calibrate your newly installed battery after completing this guide.
