5.3Headphone battery life is the playback time without recharging, measured in hours. Manufacturers measure without active noise cancellation (ANC), at medium volume (50-70%) and usually with the AAC codec, as these parameters affect battery consumption. Actual time may vary from 1% to 50%, depending on volume, active noise cancellation features enabled, codec (LDAC or other) and environmental conditions (cold, hot). It is important to consider not only the claimed playback time, but also the charging time and fast charging support.
