Sony WF-1000XM3 Battery Drains Quickly

WF-1000XM3 is a pair of unwired, earbud-style headphones that charge in a pocket-sized travel case. It has been observed that the usage life in between charges in the travel case has diminished to the point where the earbuds need to be charged often.

The Sony WF-1000XM3 earbud use life is most likely caused by the health of the battery units within each individual earbud, and they are most likely in need of replacement. To replace the battery, the face plate of each earbud must be removed, and the old battery must be replaced with a new cell. The old battery is attached to a metal clip that hold the battery cell in the earbud unit with adhesive, and it must be removed and replaced with a new cell.
