Rumors suggest that the iPhone 17 Air will be the thinnest model Apple has ever released. To achieve this slim design, the company has made some compromises, including potential reductions in battery capacity. However, speculation indicates that Apple may utilize high-density batteries to offset this limitation.

Despite these efforts, there are concerns that the company might need to introduce a battery case specifically for the iPhone 17 Air. A report from The Information indicates that internal testing has revealed that only 60% to 70% of users will be able to use the iPhone 17 Air for a full day without needing to recharge. In comparison, other current iPhone models achieve a better performance rate of 80% to 90%.

This significant disparity raises concerns about the battery life of the new device. To address this issue, Apple is reportedly planning to release a battery case as a separate accessory. While the company has offered battery cases in the past, they were eventually discontinued, along with the MagSafe Battery Pack.

This leaves iPhone users looking for additional battery solutions with few options, as many may need to turn to third-party products. Another point of concern is the forthcoming foldable iPhone, rumored to be launching in 2026. The iPhone 17 Air is said to be a testing ground for the design principles Apple hopes to implement in its foldable model.

The intention is to create a thin device by utilizing compact components. Apple seems to be aiming for improved battery technology similar to that of competitors like OPPO, which has successfully used silicon-carbon batteries for enhanced performance. However, if the iPhone 17 Air’s battery issues persist, it raises alarms about the potential battery performance of the foldable iPhone as well.
