Overview
- GalaxyClub’s filing points to a 515mAh rated battery for the Buds 4 Pro case, likely advertised around 530mAh, up from the Buds 3 series’ 500mAh rated (about 515mAh advertised).
- The reported boost applies to the charging case rather than the earbuds themselves, and real-world endurance gains are not yet clear.
- For context, the Buds 3 Pro case delivers roughly 23 hours of additional playtime with noise canceling off, which suggests any increase may be incremental.
- Leaked One UI 8.5 assets reference codenames “Handel” and “Bach” and show an icon hinting at a possible redesign, though these details remain unconfirmed.
- Coverage frames the upcoming buds against Apple’s AirPods Pro 3 with health-tracking features, while rumors place a potential launch in early 2026 alongside the Galaxy S26, which Samsung has not confirmed.
