It looks like Apple may introduce a new battery technology with the iPhone 15 that could provide a huge competitive advantage. One of the latest rumors says that Samsung is having trouble producing stacked batteries for the Galaxy S24 series, which will be released early next year. But the same source claims that all iPhone 15 batteries will be piled up, which could mean Apple’s iPhones will be the only phones with this new battery technology in 2023.
A leaker on Twitter going by the name RGcloudS says Samsung won’t be able to equip the Galaxy S24 models with stacked batteries. This source also reported on the news that Apple has secured stacked batteries for all iPhone 15 units.
This isn’t the first time we’ve heard that Samsung’s battery division is trying to bring stacked battery technology to smartphones. Interestingly, the leaker said that the new Samsung high-end phone will support 65W fast charging. It’s unclear if the charging speed is related to stacked battery technology. But electric cars also benefit from stacked battery technology, and one of the most important things for EVs is fast charging.
What is a stacked battery?
Stacked batteries refer to a new design that changes the way batteries are manufactured. Instead of rolling various materials in a battery, stacked batteries stack (stack) them on top of each other. This design change allows manufacturers to create batteries that are more efficient in terms of the space they need to occupy. Stacked batteries are more compact and allow for increased energy density. Recent reports claim an increase in energy intensity of up to 10%.
The overvaluation of space inside mobile phones further increases the importance of this technology for mobile phone manufacturers. Rumors that iPhones have increased in thickness also support the claim that Apple aims to increase battery life.
Finally, the EU’s desire to make it easier to remove and replace batteries in devices sold in the region may also be one of the reasons Apple switched battery technology. If iPhones can prove to offer excellent battery health after hundreds of charge cycles, Apple could be specifically exempted from this new rule, and stacked batteries could help.
The same rules will apply to Samsung and anyone who wants to launch devices with built-in batteries. Therefore, Samsung may also be examining this technology. The batteries produced by Samsung SDI can also be used in many non-Samsung devices.
Still, we’ll have to wait until September to see if the iPhone 15 has stacked batteries.
