Your earbuds come equipped with high-performance lithium-ion batteries and battery life span is affected by charging and usage. Follow the guidelines below to keep your batteries in great condition for as long possible.
-
Avoid using fast chargers if possible. Fast charging causes stress on the battery and will degrade it.
-
Avoid letting the battery drain completely or charging it when it’s already full. Try to keep the charge between 30% and 80%.
-
If the earbuds are stored for a long time, it’s recommended to charge the earbuds to about half-charge and then do a factory reset. Store the earbuds and case in a cool, dark, and dry place.
-
Avoid using or charging the earbuds in hot and unventilated places, 45°C/113°F and above.
-
Avoid charging the battery at low temperatures, below 10°C/50°F and using the earbuds below 0°C/32°F.
-
Avoid strong mechanical shocks such as dropping the earbuds or case on hard surfaces as it might harm the batteries.
