Apple Watch Series 6 Battery Replacement

Use this guide to replace a worn-out or dead battery in your Apple Watch Series 6.

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.
