Burst playbacknori decodes a stretch of music ahead, then lets the CPU sleep until the buffer runs low.

Measured on Android 16 ARM64 emulator (a16b), 2026-10-14, nori 0.6.0-beta.5 (perf build), Symfonium 15.1.0, Musly 2.0.2, Navic v1.0.0-alpha59. Two five-minute runs of real music across five formats, screen off; five force-stopped launches. These are emulator measurements, not phone battery-life figures. Method and raw results.
