Overview
- Android Authority identified the figures in One UI 8.5 code, which SamMobile and Android Headlines reported as 42mAh per Buds 4 earbud and 57mAh per Buds 4 Pro earbud.
- Compared with current models, the Buds 4 would drop from the Buds 3’s 48mAh, while the Buds 4 Pro would rise from the Buds 3 Pro’s 53mAh.
- Outlets note that real-world endurance will depend on chipset efficiency, ANC implementation, radios, and software power management rather than capacity alone.
- Related leaks point to a flatter-stem design, a horizontally opening case with a locator button and beeper, and features such as 360 Audio, Adaptive Noise Control, head gestures, improved Interpreter, Phone Locator, and Quick Pairing.
- Reporting frames these details as unconfirmed pre-launch leaks with an expected early-2026 Galaxy Unpacked debut alongside the Galaxy S26 series.
