With ANC enabled, one earbud charge ran 9 h 53 min, converted to hours. The linked general testing article does not specify the original test codec, host, level or ANC strength, so those settings remain unknown. This is a named reference test sample, not a measurement of every later production revision. The maker current 8 h ANC claim uses different published default/50-percent conditions, so the figures are not assumed directly comparable. The review case 50-hour discussion is not stored as a measured total.

App 3.2.7 and later is the maker recommendation for full features, without asserting that this is the latest app version. Windows conferencing guidance specifically names the Hands-Free endpoint.

The non-LDAC codec is not named, so AAC or SBC is not guessed. Tests use Anker laboratory default settings and 50 percent volume. The text normal-mode qualifier is not applied to ANC/LDAC rows as a contradictory operating setting. Call row is the separately stated ANC-off 4.5 h. ANC-on calls 4 h cannot be distinguished by the call enum, so are qualified here rather than duplicated with no visible ANC distinction. Case figures mean earbuds plus case recharges, as explicitly confirmed by the original manual, not extra case runtime alone.

90min1Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Charging FAQ directly reports around 1.5 hours to fully charge the earbuds, converted to 90 minutes. Approximate maker estimate, with adapter and initial percentage not separately stated.
Charging guidance
The maker estimates about 1.5 hours for a full earbud charge in the case, about 3 hours for the case by cable, or 3.5 hours for the case wirelessly. Ten minutes of charging is claimed to provide four hours of earbud playback. The manual lists a 5 V / 0.8 A input. Use a certified USB-C charging cable and fully dry the buds and charging port first. ANC, LDAC, calls and volume affect runtime. LDAC and multipoint cannot be used together.2Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Component-specific full-charge times come from the current maker FAQ. The original manual table only says up to 3 hours without component scope, so that generic table alone does not establish earbud-only timing. Input 5 V / 0.8 A is literal. No accepted charging watts are derived. Current A3947C guide separately lists a compatible Anker A2337 30 W adapter, which is not a bundled adapter or device input rating.
