Samsung Galaxy S24 Ultra: New battery to charge with 65 watts

With the introduction of stacked batteries in the Galaxy S24 series, Samsung finally wants to achieve higher charging speeds than 45 watts.

Samsung launched its first smartphone with 45-watt wired charging support in 2019 – the Galaxy Note10+. Nothing has changed since then. And even the modest 45 watts are still quite rare among the current Samsung phones. Things could finally change with the advent of stacked batteries, a technology inherited from electric cars. These are set to make their debut in the Samsung Galaxy S24 series.

However, not in all three models. According to a tipster on Twitter, the Stacked Battery will be included in the Samsung Galaxy S24 Ultra and possibly the Galaxy S24+. It depends on the supply chain – currently Samsung only tests batteries manufactured in a Chinese factory. The originally planned plant in Cheonan, South Korea, is still waiting for the production equipment to arrive.

One of the advantages of stacked batteries is faster charging. The Galaxy S24 Ultra is said to be able to digest up to 65 watts, compared to 45 watts for the current Galaxy S23 Ultra. According to reports, both the Ultra and the S24+ will have batteries with a capacity of 5,000 mAh. However, the Ultra will have additional cooling to achieve the higher charging speed.

There may not be enough production capacity to also upgrade the small Galaxy S24, which could stay at 25 watts for another year. However, as soon as the stacked battery technology has proven itself and the delivery bottlenecks have been eliminated, it could also be used in the future foldable Galaxy Z Flip6 and Z Fold6. By the way, Apple will probably use stacked batteries for all iPhone 15 models.
