Apple's upcoming iPhone 17 Air could be one of the lightest smartphones on the market at just 145g, but it may sacrifice battery life for a thinner profile.
Rumors suggest the iPhone 17 Air will feature a slim 5.5mm design and a 6.6-inch display, weighing less than iPhone 16e and iPhone SE 2, but with a relatively small 2,800mAh battery.
The leaked details mention a possibility of a 15-20% increase in battery capacity with a higher-density cell, but the use of silicon-carbide batteries like some Android manufacturers is not confirmed.
Apple is expected to employ under-the-hood optimizations and power-efficient components in the iPhone 17 Air to enhance battery life, similar to the approach taken with the iPhone 16e, and may introduce a battery case to address potential battery constraints.
