Overview

• Leaks from Instant Digital and leaker yeux1122 indicate the iPhone 17 Air’s battery capacity will be around 2,800 mAh, falling below the 3,000 mAh mark.
• The ultra-thin 5.5 mm chassis constrains internal space for the battery, making it the slimmest iPhone design to date at the expense of endurance.
• Internal tests reportedly found that only 60 percent to 70 percent of users would achieve a full day’s use on a single charge, compared with 80 percent to 90 percent for other iPhone 17 models.
• iOS 26’s new Adaptive Power Mode is designed to make real-time performance adjustments to extend battery life on the iPhone 17 Air.
• An optional Smart Battery Case accessory will be offered to provide additional runtime for users who need extra charge.
