Galaxy S25 Ultra may not offer stacked battery tech after all

Samsung Galaxy S23 Ultra Review AM AH 11

According to a report from South Korea in April last year, Samsung was working on a new battery technology. It is said to offer a higher energy density with a different arrangement of the cells hinting an even longer battery life for the Galaxy flagships. The stacked battery technology was first expected to come with the Galaxy S24 Ultra. However, it didn’t come with this year’s Ultra flagship. Then people were expecting the stacked battery to come with the Galaxy S25 Ultra.

Samsung may push back the stacked battery and faster charging to 2026

It’s been a while since the company has been working on the new battery tech and they also should have made some progress on developing an improved stacked battery pack for the Galaxy S25 Ultra. An upgraded 65W charging is also expected with next year’s Galaxy flagship.

However, a new rumor from Sawyer Galox on X states that Samsung may not apply the stacked battery tech on next year’s Galaxy S25 Ultra as well. The tipster is expecting Samsung to push back the new battery technology until 2026. Important to mention, that EV manufacturers have already adopted this new tech. According to the rumor, the company has also changed its mind regarding the higher 65w charging.

According to the tipster, the reason behind pushing back Galaxy S25 Ultra’s stacked battery tech and 65w charging is reducing the cost.

While Samsung’s current flagship is still one of the best in terms of battery life among Android devices and iPhones, charging is undeniably an aspect where it fails to keep up with the Chinese OEMs.

A more efficient chip should still improve battery life

Earlier, there were expectations for a bigger 5,500mAh battery capacity in this year’s Ultra flagship. With the same battery technology and capacity, the Galaxy S24 Ultra still offers a significantly improved battery life thanks to the more efficient Snapdragon 8 Gen 3 chip. According to battery Tom’s Hardware’s benchmark test, the Galaxy S24 Ultra achieves 16 hours and 45 minutes of runtime as compared to the 13-hour mark that the predecessor achieved on their testing.

As Wccftech noted, the Snapdragon 8 Gen 4 could be a reason behind Samsung’s delaying improvements in other aspects. A Qualcomm executive has confirmed that the next generation flagship chip will be more expensive than the Snapdragon 8 Gen 3 and this year’s Ultra flagship already costs $1300.
