Battery charging tips and precautions
If there is sweat or liquid on the charging contacts, corrosion may occur on the
contacts. When there is sweat or liquid on the charging terminal or earbuds,
clean them before charging the battery.
Using a power source other than the charger, such as a computer, may result in
a slower charging speed due to a lower electric current.
While charging, the earbuds and the charging case may heat up. This is normal
and should not aect the earbuds’ lifespan or performance. If the battery gets
hotter than usual, the charger may stop charging.
If the earbuds and the charging case are completely discharged, it may take a
while for them to start charging.
If the earbuds and charging case are not charging properly, take them with the
charger to a Samsung Service Center.
Avoid bending the charger. Doing so may damage or reduce the lifespan of the
charger. Never use a damaged charger.
For more information about the battery, such as the usage time, refer to the
Samsung website (samsung.com).
