If you are in W10M, install interop tools and enable offline charging in tweaks. It will trigger the offline charging

i'm using this phone since 2014 to now. and updated to Win Mobile 10. ( no official update just using 830 image. yeah working like a charm

unfortunately not any Lumia device can charge when offline mode.
