How do you find the battery level?

Hi, You can check the battery level on the phone and app, the earbuds will also remind you of the battery level by voice. When the earbud battery is only 20% left, it will remind you by voice. If you want to see a more detailed battery percentage, you can download the oladance app on Google Play/App Store. The earbuds will remind you by musicalized reminder sound when the earbuds are low battery level if you have downloaded the newest firmware( version).
