We’ve heard a lot of rumors about the iPhone 15, and the latest one to catch our attention pertains to a new type of battery technology that Apple could introduce with the flagship handset set to launch in September.
According to seasoned tipster @rgclouds (via BGR), all four iPhone 15 models will come with a stacked battery design. This is already being used in electric vehicles, and – as the name suggests – means that battery components are stacked on top of each other.
This means, in theory, the battery can be packed more tightly and provide a higher energy density. The problem is that batteries tend to run hotter, so getting it to work properly inside the iPhone will require some careful engineering.
Assuming Apple’s engineers can get it right, we could see improved battery life in the iPhone 15 series. It could also mean that the batteries are physically smaller, allowing more room inside the phone chassis for other components (or cooling mechanisms).
limited introduction
The leak doesn’t tell us much about this stacked battery technology. The technology apparently remains “limited” so it’s possible it’s not being fully implemented this time around while Apple works out some glitches.
The same source further says that iPhones with 40W wired and 20W MagSafe charging have been tested (up from 20W wired and 15W MagSafe on the iPhone 14 series) – adding that these speeds may not reach the iPhone 16. ,
We should mention that, as we’ve reported earlier, the Samsung Galaxy S24 Ultra is rumored to get the same stacked battery technology, along with increased charging speeds.
Another reason why the iPhone 15 handsets may offer better battery life than their predecessors is the introduction of the Apple A17 chip and the improved efficiency it offers. We should know for sure when these phones launch towards the end of the year.
