Hi, RONIAL
Thank you very much for your valuable feedback! We're truly grateful for your suggestions. The battery level of the earbuds can be viewed directly on your phone. If you're having trouble locating it, we recommend downloading our app — MojawaFit. With the app, you’ll be able to check the battery levels of both the earbuds and the charging case more easily, and also enjoy more convenient control and adjustment directly from your phone. Your input is very important to us, and we’ll continue working to improve your experience. Thanks again!
