The Galaxy S25 Ultra would ultimately not benefit from a new battery technology inspired by electric cars: stacked batteries. For reasons of reducing production costs, Samsung would have preferred to postpone the use of this method of manufacturing accumulators until 2026.
We are still far from the official presentation of the Galaxy S25. However, rumors about them have multiplied on the web in recent weeks. This April 29, 2024, for example, we learned that future smartphones from the South Korean firm could be equipped with a Cortex-X5, a powerful new generation CPU core from ARM.
We also know that the S25s will offer many features based on AI. For good reason, the manufacturer would have sealed a partnership with Google to integrate into its devices the next Gemini Nano 2 chip from the Mountain View firm. We could therefore expect more advanced Galaxy AI functions such as better voice interactions, a more intelligent photo section or even AI apps dedicated to productivity.
Concerning batteries, we have known for several months now that Samsung SDI, the manufacturer’s subsidiary specializing in accumulators, is working on a new manufacturing method. It is supposed to offer higher energy density (+10% according to estimates) via a different arrangement of cells. These are stacked batteries, a technology already used by Samsung “in the manufacture of Gen 5 batteries for electric cars”.
No stacked batteries on the Galaxy S25 Ultra
And while this technology was originally supposed to be used on the Galaxy S24 Ultra, Samsung preferred to change its mind. Logically, we could therefore expect its arrival on the Galaxy S25 Ultra. However, if we are to believe information from renowned insider Sawyer Galox on X, it wouldn’t be for this generation either.
According to him, if the use of stacked batteries was actually considered for the Galaxy S25 Ultra, the firm would have finally changed its mind. The same would apply to the integration of 65W fast charging. Samsung would have preferred to delay the arrival of these technologies on the S26 Ultra instead, the idea being to reduce the manufacturing costs of its next high-end smartphone.
The more than likely use of Snapdragon 8 Gen 4 on future S25s could also justify this change of heart on the part of Samsung. For good reason, Qualcomm has already confirmed that its next generation of chips will be more expensive. With a more expensive processor, the manufacturer may have decided it was wise to postpone some equally expensive upgrades.
