How does wireless charging affect the WF-1000XM4 battery life?

Use a commercially available wireless charging pad that meets the Qi standard to reduce possible damage and maintain battery life:

• After charging is complete and the charging indicator light turns off, disconnect the AC adapter cable from the charging pad and remove the charging case.
• Avoid charging or storing the headphones in a high-temperature environment. Being exposed to high temperatures for a long time may reduce the battery life.
• Remove any covers or accessories attached to the charging case when charging with the wireless charging pad to avoid damaging the battery and reducing battery life.
