Stacked battery: here is the new technology for the iPhone 15 and Galaxy S24

The past few weeks have been filled with rumors, leaks, and some solid hints about some of the new features and technology that will debut on the next generation of iPhones. In fact, as we get closer to Apple’s fall event and the upcoming iPhone 15, we have more and more solid clues about them.

We are now aware of the possibility of using the new stacked battery technology, or stacked battery in industry jargon to increase battery performance. By all indications, it will be the same technology that Samsung will use for the next generation of Android mobile phones, the Samsung Galaxy S24, which will arrive only in 2024.

At stake is innovative battery management technology, something already used by the automotive industry in its electric vehicles, with several advantages. The biggest one is actually the increase in battery life as well as the average autonomy of this power cell.

With that in mind, we have now compiled some curiosities and main aspects of how this stacked battery technology works. After all, this could be some of the biggest news for Apple’s upcoming iPhone 15 coming in September.

Two smaller cells instead of a single large battery

The concept is very simple. Instead of a single 5,000 mAh capacity battery (for example), we will have two batteries of about 2,500 mAh each. In practice, this allows you to increase the charging speed of the batteries, and can also increase the overall autonomy of the mobile device.

This is because it is possible to use more than one power cell, housed whenever possible within the mobile device. Thus, it may be possible to increase the overall autonomy of the mobile telephone, without necessarily increasing its thickness.

For example, we can put two smaller cells next to each other, arranged side by side, instead of one large, thicker battery. The goal is to fit as much battery power capacity as possible into a compact space.

At the same time, it is also possible to reduce the charging time of these batteries, since in practice we will have smaller power cells. As such, they will charge faster, even if the total power of the charge does not increase exponentially.

Samsung Galaxy S24 can use this battery technology

Like the upcoming Apple iPhone 15, the Samsung Galaxy S24 could also employ stacked battery technology. The motivation for this will be the same, a greater capacity (about 5,000 mAh in the Galaxy S24), without increasing the thickness.

In view of the above, in the Samsung Galaxy S24 we have a general increase in battery capacity. Something that is also expected for next-generation iOS phones, Apple’s iPhone 15 that will arrive next September.

On the other hand, the Samsung Galaxy S24 generation should only be presented in February 2024, which is still several months away, but it is certainly already in the final stages of development.

In short, we have longer battery life in the latest generation smartphones. Something that was already expected is certain, however, it must also be attributed to the increasingly efficient processors, along with these new technologies for the battery.

In any case, the truth is that the duration between charges continues to be one of the biggest, if not the biggest concern for mobile device users. Therefore, anything that can help improve this aspect will necessarily be welcome.
