How can both the buds have the same battery level?

I've used the left bud for more than 30 mins before I used the right bud together with it.

Hmmmm isn't that strange? 

When the battery is low, it specifies which bud has the lower battery level. And it's usually the right bud that dies first.

Hi, EllisKai!

Thanks for asking this question here! This is a completely normal operation. Only the earbud with the lower battery level is shown in the Galaxy Wearable app when there is no or slight difference between the two buds. This doesn't mean that the two buds have the same battery level. It just means that there's no significant difference between the battery levels of the two buds. If the battery levels of both buds are significantly higher, then the two battery levels of both buds will be shown on the Galaxy Wearable app.

I hope this brief explanation helps in understanding how the visual battery representation works in the Galaxy Wearable app.
