The Importance of Battery Innovation in Samsung’s Galaxy S Ultra Series

Every year, Samsung unveils a new Galaxy S Ultra model with enhancements in camera quality, display brightness, and chip power. However, a crucial aspect that remains stagnant is the battery.

Since the release of the Galaxy S20 Ultra in 2020, Samsung has continued to use the same 5000mAh battery in all its subsequent Galaxy S Ultra devices, with no signs of improvement.

Reports indicate that the upcoming Galaxy S26 Ultra, set to be announced on 25 February, will likely maintain the 5000mAh capacity or see a slight increase to around 5400mAh.

Unfortunately, this falls short compared to competitors offering batteries ranging from 6000mAh to 8000mAh.

While Samsung and Apple have remained stagnant in battery innovation, competitors have taken the lead in this overlooked area.

For instance, the recent OnePlus 15 boasts a massive 7300mAh battery, while the Oppo Find X9 Pro features a substantial 7500mAh battery. These brands have embraced silicon-carbon battery technology, offering more power without increasing bulk.

The lithium-ion battery issue

Opposing Samsung’s conventional lithium-ion cells, competitors have adopted silicon-carbon batteries by replacing part of the graphite in the anode with silicon. This chemistry allows for greater power capacity without a larger footprint.

These silicon-carbon batteries not only excel on paper but also in real-world usage. They offer longer battery life and faster charging capabilities, providing users with extended usage on a single charge.

While Samsung may attribute its adherence to lithium-ion batteries to concerns about silicon expansion during charging, competitors have proven the reliability and efficiency of silicon-carbon batteries.

For Samsung enthusiasts, the lack of a significant battery upgrade in the upcoming S26 Ultra model is disappointing. In the ever-evolving landscape of smartphone technology, meaningful upgrades in essential areas like battery performance are crucial.

Enhanced processors and advanced cameras are appealing, but a device that can last a full day on a single charge significantly impacts user experience. Samsung may eventually need to adopt silicon-carbon batteries to stay competitive and enhance its market appeal.
