iPhone 15 Pro and 15 Pro Max: The batteries are so big, you’ll forget to charge your phone
Smartphone manufacturers are constantly in search of longer battery life. This isn’t new for Apple, and with rumors swirling around the iPhone 15 Pro and 15 Pro Max, we’re eagerly awaiting their advancements in this crucial field.
Significant upgrades are on the horizon for Apple’s flagship smartphones, featuring a more durable titanium frame and the inclusion of USB-C, but we’re particularly excited to witness their extended longevity in battery life with the iPhone 15 Pro Max.
There are several reasons for this, which we’ll delve into below. Last year’s iPhone 14 Pro Max secured a place in our top 5 list for best phone battery life, showcasing itself as a true flagship phone. In Tom’s Guide battery test, it reached an impressive 13 hours and 39 minutes, including continuous web browsing at 150 nits screen brightness.
While it was enough to earn a spot in the top 5, it still falls short of the Asus ROG Phone 7 Ultimate’s 18 hours and 32 minutes. We can see the gap closing with the iPhone 15 Pro series, especially as we consider all the significant upgrades that Apple had in store for its new smartphones. Here’s why.
Big Battery, Prolonged Performance Undoubtedly, larger batteries would contribute to improving the battery life of the iPhone 15 Pro. It’s quite possible, considering all the rumors, that the iPhone 15 Pro and 15 Pro Max could feature even bigger battery cells. They’re rumored to house 3,650mAh and 4,852mAh battery packs respectively, potentially making the iPhone’s largest battery yet. In comparison, the iPhone 14 Pro holds a 3,200mAh battery, while the iPhone 14 Pro Max boasts a 4,323mAh cell.
By simply combining larger batteries, we can expect to see extended performance with the iPhone 15 Pro and 15 Pro Max. While larger batteries inherently add bulk to the phone’s size and weight, Apple might introduce a new battery technology that can address this concern.
Advantages of Stacked Batteries: Higher Density Batteries today are being crafted in entirely new ways, departing from conventional norms. A possibility that could enhance the long life of the iPhone 15 Pro and 15 Pro Max’s batteries is the use of stacked batteries, similar to those utilized by many electric vehicles.
These batteries are built in a way that minimizes wasted space while creating room for more active material. As compared to current smartphone batteries, iPhones could benefit from higher power density without compromising on thinness. However, introducing this new battery technology does come with a downside – the increased power density could lead to higher heat generation.
There’s no guarantee that we’ll see stacked batteries on the iPhone 15 Pro series, but Apple would need to come up with a solution to handle heat buildup more efficiently.
Power Efficiency of A17 Bionic While larger batteries can naturally result in better battery life for the iPhone 15 Pro and 15 Pro Max, there’s something else that could play a role – the power efficiency of the A17 Bionic chip. The buzz surrounding Apple’s silicon is that it will debut with the iPhone 15 Pro series, and it’s noteworthy because it will be Apple’s first chip built on the 3-nanometer process.
We could potentially witness a 35% increase in power efficiency in the battery life of the iPhone 15 Pro and 15 Pro Max due to the A17 Bionic chip. This is because the 3nm manufacturing process of the A17 Bionic can fit more transistors in the same space compared to the 3nm process of the A16 Bionic chip that debuts with the iPhone 14 and 14 Pro Max. This, undoubtedly, would benefit not only the processing power of the iPhone 15 Pro series but also its battery life.
