Apple’s $99 iPhone Battery Pack Extends Life to 40 Hours

Apple has launched a new MagSafe battery pack. It is designed specifically for the ultra-thin iPhone Air. The accessory became available for purchase on Tuesday, September 9, 2025.

The $99 battery aims to solve the power constraints of the slim new iPhone model. It promises to significantly extend daily usage without adding bulk.

Specifications and Performance Enhancements

The new MagSafe Battery provides up to 12W of wireless charging. When connected to a power adapter and the iPhone Air simultaneously, it delivers a faster 20W charge.

Apple claims the accessory can add up to 65 percent more charge. This extends video playback to 40 hours. Streaming video runtime increases to 35 hours.

According to Apple, this makes the iPhone Air’s total battery life longer than any other iPhone model. The battery pack is described as thin and pocket-friendly.

Compatibility and Market Position

The product listing notes compatibility only with the iPhone Air. This suggests it may not fit iPhone 17 Pro models due to their larger camera bumps.

This move highlights Apple’s strategy for its thinnest iPhone ever. It offers a solution for users who prioritize design but need more power.

The battery pack provides a flexible power solution. Users can choose between portability and extended battery life as needed.

The new iPhone Air MagSafe Battery offers a practical solution for power-hungry users. It effectively complements the device’s sleek design. This accessory ensures the ultra-thin iPhone remains practical for all-day use.
