JAKARTA - The Samsung Galaxy S25 Ultra will launch soon, but the public must be ready to be disappointed. Because this flagship phone may not experience an increase in battery, it remains at 5,000mAh capacity and 45W charging. The slimmer S25 Ultra design is thought to be the reason for the absence of an increase in batteries, due to the difficulty of inserting a larger battery into a thinner phone.

While there is no increase in battery, the new Snapdragon 8 Gen 4 processor can increase battery life due to better power efficiency. The Galaxy S25 Ultra seems to be another example of Samsung's inability in terms of batteries.

Trusted leaker Ice Universe shared on X that Samsung is expected to deliver the successor to the Galaxy S24 Ultra with the same battery capacity and charging speed as the previous top-of-the-line variant.

This means the Galaxy S25 Ultra is estimated to remain with a 5,000mAh battery. So, don't be surprised if the battery life is almost the same as the previous model.

Attaching to the same battery capacity in Ultra line while competitors continue to innovate weakening Ultra brand image as technology leader. Continuing this in 2025 is not what you expect from flagship devices.

The Galaxy S25 Ultra is also expected to retain the same 45W fast charging as its predecessor. While that's better than Apple's offerings, it's still less than any other favorite Android phone that drives charging speeds of more than 100W.

When the Galaxy S20 Ultra debuted in 2020, its 5,000mAh battery and 45W charging set new standards for flagship phones. These features are lowered to the Galaxy S21 and S22 Ultra. Unfortunately, it seems that the Galaxy S25 Ultra will continue this trend without increasing batteries.

However, the slimmer design of the Galaxy S25 Ultra may explain the absence of an increase in batteries. Imposing a larger battery into a thinner phone while retaining advanced camera systems and other internal components is a tough engineering challenge.

Even without an increase in battery capacity, the Galaxy S25 Ultra is expected to provide a better battery life than its predecessor. Thanks to the Snapdragon 8 Gen 4 processor, which was built with TSMC's advanced 3nm technology, this phone should be more power efficient, allowing for longer use with one charge.

Previous rumors also suggested that Samsung might use AI to improve battery performance. However, be wise to take this claim with the current grain of salt, as the official release of the Galaxy S25 Ultra is still a few months away.
