Here are the steps:

1) Use the earbuds regularly to avoid over-discharge which can harm the lifespan of the earbuds' battery. We recommend using Liberty 3 Pro at least once a month.

2) Charge the earbuds after you use them. In order to improve the battery's lifespan, do not always wait until there's 20% power remaining or less to charge them.

3) If you are storing the charging case, make sure there are at least 2 lights that light up on the case to ensure there is enough power.

4) Open the charging case's lid at least once a month to ensure the earbuds start charging. 

5) Regularly clean the charging pins on the earbuds and charging case.

6) Keep the ear tips clean. 

7) If it comes into contact with liquid, use a hairdryer on the 'cool' setting to dry the case.
