# **Discover the breakthrough battery technology coming to iPhone 15** **Stacked battery technology is supposed to bring a breakthrough in the smartphone industry that has many limitations on battery life.** Low battery notifications on smartphones are something that many people find annoying, especially if there is no charger nearby. So the emergence of the stacked battery technology that companies like Samsung and Apple are aiming for promises to offer many benefits. Conventional rechargeable batteries are made using the rolling method, which involves rolling the battery components into a cylinder. While this method has worked for many years, stacked batteries can provide even greater charging capacity. It is a technology that uses a stacked structure, or stacked cell. So how is this achieved? By stacking layers of positive and negative poles on top of each other, the electrodes inside the battery are folded to form a Z shape. This process, known as lamination, allows for greater battery density, high capacity, and longer battery life. Furthermore, stacked batteries can save space, a limited resource in today’s thin and light smartphones. Stacked batteries are often found in modern electric vehicles, with a design that looks different from a smartphone, but will have the same structure and idea. ## Advantages With the current level of smartphone usage, especially running software, the battery can run out quite quickly. Some devices do not even have a full day of operation to recharge the battery. Increasing the battery capacity can help, but it will take up more space and add weight to the machine. This is where stacked batteries come in handy, as their increased density allows a longer charge to last without much size. The result is a longer battery life. Furthermore, stacked batteries could make modern smartphones safer and more sustainable because they are adaptable and can be modified easily if something goes wrong.

Not only the iPhone 15 series, but sources also indicate the upcoming Galaxy S24 Ultra may also adopt stacked battery technology. The source says that the batteries of the Galaxy S24+ and S24 Ultra are both 5,000 mAh, but it is not clear whether the Galaxy S24+ will use a stacked structure. Besides, the Galaxy S24 Ultra with stacked battery technology will reach 65W fast charging, a huge leap over the 45W maximum charging speed achieved by the Galaxy S23 Ultra. However, Samsung’s product will only be released in early 2024, so the iPhone 15 is likely to be the first smartphone to adopt stacked battery technology and usher in a huge step forward in the industry, allowing batteries to last a whole week. #iphone #piniphone
