@Korkkiruuvi: when you compare with Android, is it with AOSP9 or something else? I don't know whether AOSP9 is available for download, but that would be closest to compare with. Although, I haven't worked on USB audio and don't plan to as there is no hardware to test it nor use it.

@lal: while I have XZ2c for development/backup, haven't used it as a daily driver and cannot comment on battery life. XZ2, with my usage, can probably last 2 days. Frequently, I don't swing from 100->20, but keep it in the range 30-80. Looking at the stats, it is about 40% battery per 24h with my usage
