Samsung Galaxy S26 Ultra Battery Upgrades to 5200 mAh
Samsung Galaxy S26 Ultra Set for Major Battery Upgrade: 5200 mAh and 60W Fast Charging
Samsung is finally giving the Galaxy S series Ultra a long-awaited boost in battery performance. After five generations with the same 5000 mAh battery and a maximum 45W fast charge, the upcoming Galaxy S26 Ultra is rumored to feature a larger 5200 mAh battery and faster 60W charging, signaling a significant step forward for power users.
Battery Upgrade Details
According to leaks from Weibo insider Instant Digital, the Galaxy S26 Ultra will feature a 5200 mAh battery, an increase of 4% over the S25 Ultra. While modest, this marks the first battery expansion in the Ultra series in several years. Reports from PhoneArena and TechRadar suggest this upgrade will provide longer screen-on times, especially when paired with the efficient Snapdragon 8 Elite Gen 5 chipset.
The fast charging system is also improving. Chunvn8888 reports that the device will start charging at 55W from 0–15%, then reduce to 45W up to 70%, allowing a 0–80% charge in just 30 minutes, significantly faster than the S25 Ultra. This improvement addresses long-standing user complaints about slow charging speeds.
Launch Date and Location
The Galaxy S26 Ultra is expected to launch alongside the S26 and S26 Plus at Galaxy Unpacked 2026 in San Francisco, on February 25, 2026, according to Money Today and NotebookCheck. Samsung reportedly chose the city to highlight the AI capabilities of its flagship series, aligning with the company’s focus on AI-powered mobile experiences.
Market Context and Competition
This battery and charging upgrade appears aimed at keeping pace with competitors like the iPhone 17 Pro Max, which also boasts a 5000 mAh battery. Some reports from Chinese certification boards list a slightly smaller 4855 mAh cell, but multiple leaks confirm the 5200 mAh figure as the likely reality.
With faster charging and extended battery life, the S26 Ultra is poised to become a standout flagship in a highly competitive early-2026 smartphone market.
