Apple’s Foldable iPhone Set to Redefine Battery Standards
Apple is poised to make a significant impact in the foldable smartphone market with its upcoming device, rumored to feature the largest battery ever seen in an iPhone. According to the leaker Fixed Focus Digital, the foldable iPhone’s battery capacity could exceed 5,500 mAh, surpassing the 5,088 mAh battery of the current iPhone 17 Pro Max.

This substantial battery capacity is expected to outshine competitors. For instance, the Google Pixel 10 Pro Fold houses a 5,015 mAh battery, while the Samsung Galaxy Z Fold 7 comes with a 4,400 mAh battery. Apple’s focus on enhancing battery life is evident, with reports indicating that the company is testing batteries ranging from 5,400 to 5,800 mAh for its foldable device.

To achieve this, Apple is reportedly utilizing high-density battery cells, a technology that allows for greater energy storage without increasing the physical size of the battery. This approach aligns with Apple’s commitment to maintaining sleek and lightweight designs while delivering superior performance.

In addition to the impressive battery, the foldable iPhone is expected to feature a 7.8-inch crease-free inner display and a 5.5-inch cover display. The device is also rumored to incorporate Touch ID integrated into the side button, a departure from the Face ID system used in recent models.

Apple’s emphasis on battery life extends beyond capacity. The company is reportedly refining the display driver integrated circuit (IC) to enhance power efficiency. By reducing the display driver IC from 28nm to 16nm, Apple aims to lower power consumption, thereby extending battery life without compromising the device’s slim profile.

The foldable iPhone is expected to launch alongside the iPhone 18 Pro and iPhone 18 Pro Max later this year. With its combination of advanced battery technology, innovative design, and powerful hardware, Apple’s entry into the foldable smartphone market is set to redefine user expectations and set new industry standards.
