Apple’s iPhone 15 model, which has not yet been released, has been the subject of a lot of speculation lately. Apple’s next flagship iPhone offerings are said to have great charging speed potential. Apple’s iPhone 15 is said to come with a multi-layer battery, thanks to a major upgrade in battery technology. The multi-layered approach is expected to extend battery life and allow the iPhone 15 to charge up to 40W.

The iPhone 14 now has a maximum charging speed of 30W, and the jump to 40W is quite significant. @RGcloudS, a Twitter commentator, says that increasing the wired power to 40W for the iPhone 15 could result in charging speeds of up to 20W via MagSafe. But since some speculation links the tech to the iPhone 16, there’s no guarantee that the new tech will appear on the iPhone 15. It is also believed that Apple’s switch to USB-C will increase the charging speed for the next generation iPhone.

Stacked battery is in the way, but limited

Probably only for 24U and 24+
or just 24U

Meanwhile,
apple used it on all iP15 series

24U and 24+ 5000 MaH “rated”

But 24U stacked construction is different
They applied cooling gel to cool it. For 65W and stability https://t.co/8khM2oAToc

However, it is clear that there are several other reasons for the possible increase in the charging speed of the iPhone 15. First, the bundled battery could mean that Apple may have circumvented the overheating issue in such a scenario. However, 40W charging is still far from the gold standard of over 100W charging speeds.

The announcement of the iPhone 15 is scheduled for September 2023. Expect more speculation about the iPhone 15 as the release date approaches. The model is expected to highlight the durability and performance Apple is known for.
