I'm not 100% sure, but after the 2.29 firmware update, my Nokia BL-5C battery goes flat even when it is not powered on for two weeks or so. At first I thought simply a bad battery and tried another one (approx. same age), but this went zero as well. Before the firmware update, that first battery never depleted that fast. FYI those batteries are from my old Nokia phone and I stored them separately at 100% I guess. When used for the first time inside the RK008 in March 2024, it was still around 80%!
That's why I think it has something to do with the new firmware but could be wrong of course. I will now charge both batteries again 100% and update within 2-3 weeks if they are also deplete when NOT inside the RK008.
