We are currently working on adding this functionality to the Nordic Thingy:52 App, and it will be added in a future release. The Thingy:52 already have the battery-service, so it's possible to “manually” read it using nRF-Connect.
@shanestarita From the FW code, there does appear to be a undocumented battery level service 0x180F for the service ID, battery level char is 0x2A19. Not sure it works, hope this helps.
I see battery level in the 2.0.0 firmware as a battery icon with % of max charge upper left of the flyout menu. Would also be nice to have the icon change when charging is occuring.
