Will the iPhone 15 series have fast charging power exceeding 30W with stacked batteries?

【Phoneauto News】On July 24th, it was reported that Apple plans to use stacked battery technology in the iPhone 15 series. This battery technology can reduce heat generation, improve charging speed and battery life, and provide more available power. In simple terms, the iPhone 15 series with stacked battery technology not only has a more durable battery, but also faster charging speed. The power may reach 40W, which can be considered a huge improvement. It is said that the next generation of Samsung’s flagship phones will also adopt this battery technology.

Previously, there were leaks that the battery capacity of the iPhone 15 series has been greatly increased. The battery capacity of the iPhone 15 is 3877mAh, the iPhone 15 Plus is 4912mAh, the iPhone 15 Pro is 3650mAh, and the top-of-the-line iPhone 15 Pro Max is 4852mAh. This is much larger than the battery of the iPhone 14 and even catches up with the battery capacity of some Android phones.

Now it seems that the iPhone 15 series is not using the original battery technology route, but the latest stacked battery technology. I wonder if this will also improve the thinness of the iPhone 15 Pro series.

New energy vehicles and smartphones can sometimes learn from each other’s ideas. Stacked batteries have been widely used in the field of electric vehicles due to their high energy density.

It is understood that the stacked battery unit uses laminated manufacturing technology, where the battery components and separators are folded into a zigzag shape. This structure means that it has a higher energy density compared to wound batteries, and the heat is distributed more evenly, resulting in a relatively longer battery life. However, smartphones are much smaller electronic devices, and it requires more precise manufacturing technology to make the battery in this structure.
