I see there was another JELOS update yesterday, 20240121, for all devices. Woot! Under the Change Log, there is "Fixes a long standing issue with RK3566 devices causing drain after being charged while devices are powered off." So no longer coming back to the RGB30 after a few days of non-use and seeing it's nearly dead? That will be awesome!
Sincere thanks to the developers of JELOS for all their hard work.
