4. Test the battery when playing music.
ANC is turned on by default. If you want to test the playtime in Normal mode, switch to Normal mode first.
Normal: 10 hours of playtime for earbuds and 50 hours for the charging case.
ANC: 8 hours of playtime for earbuds and 40 hours for the charging case.
Transparency: 8 hours of playtime for earbuds and 40 hours for the charging case.
LDAC and ANC Mode: 5 hours of playtime for earbuds and 25 hours for the charging case.
LDAC On (ANC Off): 6 hours of playtime for earbuds and 30 hours for the charging case.
Calls (ANC Off): 4.5 hours of use.
