Samsung Galaxy S24 Ultra (and iPhone 15 series) tipped to launch with upgraded EV-inspired battery tech
Samsung may have chosen to leave the Galaxy Note name behind; nevertheless, the S Pen-toting S23 Ultra has inherited the nearly 4-year-old 10+'s maximum charging speed. The OEM calls the persistent, yet stagnating, 45W rate a "Super Fast Charging" standard for smartphones - regardless of how many other brands race ahead with technology that can charge batteries of the same size as the premium Ultra variant in half the time or less, using similar USB type-C ports.
However, things might finally start to improve for the Galaxy S24 Ultra on its release. The leaker RGcloudS backs it to introduce a new type of battery, developed by Samsung's SDI division for faster and more reliable charging. This is because it apparently ports the advanced stacked structure also designed with electric cars in mind to Android smartphones for the first time.
Samsung's inaugural stacked battery is now believed to feature in the S23 Ultra's successor - and that of the S23+ if it is very, very lucky. That detail sounds reasonable - until it meets with the concurrent rumor that Apple has upgraded the iPhone 15 and 15 Plus to the same technology as well as the higher-end 15 Pro and Pro Max.
Then again, the S24 Ultra just might be able to call the equally cutting-edge "cooling gel" thermal management system for its new battery its own. Nevertheless, for all this putative (and long overdue) advancement in Samsung mobile device power tech, it is also slated to raise the Ultra's top charging speed to no more than 65W - thereby still lagging behind even mid-rangers from other brands in 2023.
