How to see battery level (percentage) in Nebula II?

Simple question… I’ve been searching in the settings, apps, forum and Google, but haven’t found the answer. Google Assistant always says it’s 42%, not much helpful.
I also wonder about the light indicator on the power button. Is it green for over 95%, then yellow or blue? What do those colors exactly mean?

@_Daniel Thanks for your inquiry. For Capsule II, it doesn’t have the feature of showing battery level in percentage and we apologize for the inconvenience caused.

Below are the indicator reference:

Flashing red: low battery
Solid red: charging
Solid green: Fully charged
