Rumors suggest that Samsung is finally preparing significant changes to the battery capacity of its high-end smartphones. The Galaxy S25 Ultra, launched in 2025, maintained the traditional 5,000 mAh of the Ultra line since the S20 Ultra. However, recent leaks suggest that the Galaxy S26 Ultra, expected in January 2026, could bring a higher capacity.
Speculations indicate a 5,200 mAh battery for the premium model. Essa change represents a modest increase, but marks the breaking of the 5,000 mAh barrier in the company’s flagships.
- Increase allows greater autonomy in intense use.
- Chinese competitors already offer batteries above 6,000 mAh in premium models.
- Samsung prioritizes software optimizations and energy efficiency.
Battery history on line Ultra
The Samsung adopts 5,000 mAh in the Ultra models since 2020.
This choice balances thickness, weight and battery life. The Galaxy S25 Ultra performed well in tests, with up to 17 hours of continuous use, thanks to the efficient Snapdragon 8 Elite processor.
For the S26 Ultra, the increase to 5,200 mAh comes with possible improvements in fast charging, with rumors of 60W support.
Advances in the entry line
The Samsung tests greater capabilities in affordable models.
The Galaxy A07 5G, recently certified at Anatel at Brasil, features a 6,000 mAh battery. Isso surpasses the 5,000 mAh of the A06 5G and A07 4G.
The entry-level model gains an extra 1,000 mAh, offering up to two days of moderate use.
This strategy introduces larger batteries into budget devices before flagships, similar to the early adoption of punch-hole screens.
Comparison with competitors
Rival brands advance battery technologies.
Companies like Xiaomi, Vivo and OnePlus use silicon-carbon cells for capacities above 6,000 mAh or 7,000 mAh in flagships.
Samsung adopts a cautious approach, prioritizing safety and gradual energy density.
- Galaxy S26 Ultra: 5,200 mAh possible with faster charging.
- Chinese models: often 6,000 mAh or more, with charging above 100W.
- iPhone 16 Pro Max: around 4,685 mAh, focused on efficiency.
Expectations for Loading
Rumors point to developments in the charging of the S26 Ultra.
The model can support 60W wired, compared to the current 45W, reducing recharging time.
Wireless charging remains at around 25W, with Qi2 compatibility.
Tests in emerging markets
The Galaxy A07 5G with 6,000 mAh is aimed at regions like Brasil and Índia.
There, prolonged autonomy is valued in affordable devices.
Brazilian certification confirms the component, with launch scheduled for the coming weeks.
These changes indicate that Samsung responds to criticism about stagnation in flagship batteries. The small increase in S26 Ultra signals future adjustments, while the A line advances more quickly.
