Overview
- GalaxyClub’s finding, echoed by SamMobile and Gizmodo, indicates the Buds 4 Pro charging case is rated at 515mAh versus 500mAh for Buds 3 series cases, which could translate to roughly 530mAh advertised.
- The real-world playtime impact of the case’s larger battery is not yet known, with the Buds 3 Pro case previously offering about 23 hours of extra listening with ANC off as a reference point.
- Leaked One UI 8.5 assets referencing the codenames “Handel” and “Bach” suggest Buds 4 and Buds 4 Pro are in the works, though any implied audio‑fidelity focus remains speculative.
- It is unclear whether the non‑Pro Buds 4 case will see the same battery increase, and no additional specifications have been confirmed.
- No release date has been announced, with some reports pointing to a possible rollout next year, as the lineup is expected to face Apple’s AirPods Pro 3, which offer health features such as heart‑rate monitoring.
