If I’m correct, the battery will charge up to 100% and then stops charging, while still connected to the adapter.
It would be great to have an option to stop charging at 80% (or any other value) when connected to the adapter.
The battery will degrade faster when charged up to 100% multiple times.
When you mainly use the projector with the power adaptor it would be great that the battery charges up to 80% (instead of 100%) and then stops charging while still connected to the power adapter.
Or if it’s easier to implement, just a toggle to stop charging the battery (as suggested by ThunderStrk)
This way you can prolong the battery life during the lifespan of the projector.
