Charging for 10 minutes using wired charging or when the charging case has more than 80% battery, with the volume adjusted to 50%, music in AAC encoding format, and noise cancellation turned off, can provide 4 hours of battery life. Actual battery life is influenced by factors such as volume, audio source, environmental interference, product features, and usage habits.

**Battery life and charging data come from Huawei labs with the following testing conditions: volume set to 50%, AAC format used, and default settings for other functions. The test results are for reference only. Actual usage may vary depending on the volume level, audio source, connected devices, environmental interference, enabled features, and usage habits.

Music playback (with noise cancellation enabled): 7 hours after a full charge and 35 hours when used with the charging case*

Music playback (with noise cancellation disabled): 10 hours after a full charge and 50 hours when used with the charging case**

*Battery life data comes from Huawei lab tests, in which audio was played at a 50% volume level and with ANC disabled in AAC mode, and while using a HUAWEI Pura 70. The default settings were used for other features. Actual battery life may vary depending on the volume level, audio source, environmental interference, product features, and usage habits.

**Battery life data comes from Huawei lab tests, in which audio was played at a 50% volume level and with Wind noise reduction mode disabled but ANC enabled in AAC mode, and while using a HUAWEI Pura 70.
