Use this guide to remove or replace the battery on your Sony WH-1000XM3 headphones.

If your battery is swollen, take appropriate precautions.

For your safety, discharge your battery below 25% before disassembling your headphones. 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.

  1. Before beginning any repairs, turn off your headphones. The earcup cushions of the Sony WH-1000XM3 are held in place by small plastic clips and it's the same removal procedure for both, the left and the right cushion. In case you want to replace the battery you're required to remove the RIGHT earcup cushion.

    • Pry up the battery intermittently to work it away from its adhesive.

    • Remove the battery.

    • Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

    • Remove old adhesive backings before installing new adhesive and clean the relevant areas with isopropyl alcohol (>90%).

    • If your replacement battery does not come with replacement adhesive 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 place where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

Abschluss

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

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

Thank you! This is a very detailed and helpful guide. I especially appreciated the battery calibration tip at the end of it! The battery removal was probably the most difficult part, as the adhesive was strong. Slowly working the opening pick under the battery as directed did the trick, though.
