AAC and SBC each allow up to 30 hours with ANC on or 40 hours with ANC and Ambient Sound Mode off. LC3 over compatible LE Audio has the same 30/40-hour claims. LDAC allows 26 hours with ANC on or 36 hours with both noise-control modes off. Powered analog playback allows 28 hours with ANC on or 38 hours with both modes off. Each named codec is retained in its own row. Sony warns that Equalizer, DSEE Extreme, Speak-to-Chat, Service Link, and other changes to default app modes reduce these maxima. Playback volume and LDAC bitrate are unspecified. Communication durations are excluded. The 25 to 35°C footnote attaches to the quick-charge estimates, so it is not assigned as a continuous-runtime test condition.
