@dos As a point of comparison, i did the exact same 30 min workout on my #FLX1 in the same conditions, only gapless + flatpak app for a more apples to apples comparison. There wasnt any lag at all and no music cutout during the scan. Used about 9%/30mins so 18%/hour estimated. So not too far off but the big difference is the FLX1 has really good standby so even if the workout is at the end of the day its more likely that you will have enough juice at that time.
