Introduction
Follow this guide to replace the battery on the Sony WH-1000XM4 wireless headphones.
Most single-celled lithium-ion replacement batteries with the same battery connector should work—as long as they physically fit.
Note: If you’re having battery charging problems, follow this procedure to disassemble your headphones, disconnect the battery for 15 minutes, reconnect it, and see if the problem is fixed before replacing the battery.
To minimize risk of damage, turn on your headphones and allow the battery to fully discharge before starting this procedure. If a charged lithium-ion battery is accidentally punctured, a dangerous and uncontrollable fire may result. If your battery looks puffy or swollen, take extra precautions.
What you need

Place your headphones onto a work surface, ear pads facing up.

Insert the flat end of a spudger into the gap you've created, between the edge of the cushion and the frame.
-
Pivot the spudger down to unclip the long edge of the ear pad.
-
-
-
-
Align the cushion over the speaker and press them firmly together to snap it into place.

Press around the entire edge of the cushion, making sure all the clips have engaged.
