A fresh leak has added to the growing anticipation around Samsung’s next-generation wireless earbuds, the Galaxy Buds4 Pro and standard Buds4. After earlier reports showcased design changes and a shift toward a more premium aesthetic, the latest information highlights notable improvements in the battery capacity of the upcoming models.
According to leaked documentation circulating in tech forums and social channels, the Galaxy Buds4 Pro will feature a 57mAh battery in each earbud. This marks an increase over the 53mAh capacity found in the Galaxy Buds3 Pro, suggesting Samsung is prioritising longer playtime and improved endurance without dramatically altering weight or form factor.
Analysts believe that even a modest improvement in battery size could translate into meaningful changes in usability, especially when paired with efficiency gains from Samsung’s updated chipset, audio optimisations, or AI-powered features expected to ship with the 2026 lineup. Enthusiasts are already speculating that longer ANC performance and extended call times may be key areas of enhancement.
The standard Galaxy Buds4 are also rumoured to receive battery upgrades, although exact capacities have not been publicly disclosed. Early renders and supply chain talks point to a familiar shape with subtle refinements, with Samsung reportedly aiming to align both models more closely with its flagship ecosystem of foldables and Galaxy AI devices.
Battery life has increasingly become a competitive differentiator in the wireless audio market, where premium models must balance lightweight design with advanced features such as adaptive ANC, dynamic EQ, beamforming microphones, and spatial audio. Incremental improvements are often crucial, especially for consumers seeking all-day usage without charging anxiety.
The leaks arrive ahead of Samsung’s next major hardware cycle, expected in early 2026, where the company may launch multiple products including earbuds, foldable smartphones, and AI-enabled accessories. With rivals such as Apple, Sony, and Google also pushing mid-cycle upgrades, Samsung appears determined to strengthen its position in the high-end audio segment.
While specifics on pricing, colour variants, and new features have yet to surface, the latest leak signals that Samsung is continuing its iterative approach to hardware upgrades rather than radical redesigns. For users who prioritise endurance and premium sound, the Galaxy Buds4 Pro could emerge as a substantial step forward.
