Tim Cook Promises Extended Battery Life for the New iPhone Air: Details Inside

Apple’s Communication Challenge with the New iPhone Air

Apple faces the challenge of explaining to potential iPhone Air customers that the reduction in battery life does not match the reduction in its thickness, which is just 5.64 mm. Apple has innovated in several ways to maximize battery size while reducing the phone’s power consumption. This includes removing the SIM card tray and incorporating the new C1X modem as well as Apple’s first self-designed Wi-Fi and Bluetooth chip, named Apple N1.

Battery life was the first topic Jim Cramer brought up with Tim Cook during an interview at a new Corning production line, which makes glass for iPhones and Apple Watches, when Cook showed him the iPhone Air. Cook’s response was brief but reassuring:

The battery life is outstanding. You’re going to love the battery life. […] We’ve rethought everything from the ground up. It’s only compatible with eSIM, which allowed us to enlarge the battery where the physical SIM card used to be. It’s an incredible innovation.

Specifically, the iPhone Air features a battery capacity of 3,149 mAh, compared to 3,692 mAh for the iPhone 17, 4,252 mAh for the iPhone 17 Pro, and 5,088 mAh for the iPhone 17 Pro Max. Until actual tests are conducted, one must rely on Apple’s estimated battery life based on video playback and streaming:

• iPhone 17: 30 h in playback, 27 h in streaming

• iPhone 17 Air: 27 h in playback, 22 h in streaming

• iPhone 17 Pro: 31 h in playback, 28 h in streaming

• iPhone 17 Pro Max: 37 h in playback, 33 h in streaming

Although the iPhone Air’s battery life is slightly less compared to other models in the lineup, the difference isn’t as significant as one might expect. Moreover, it’s important to note that the new iPhone 17 range has a generally improved battery life compared to previous Apple smartphones. Contrary to what one might think, the iPhone Air’s battery life surpasses many older models, better than the iPhone 15 Plus, nearly on par with the iPhone 16 Plus, and identical to the iPhone 16 Pro. Here’s a comparison with previous generations:

• iPhone 16: 22 h in playback, 18 h in streaming

• iPhone 16 Plus: 27 h in playback, 24 h in streaming

• iPhone 16 Pro: 27 h in playback, 22 h in streaming

• iPhone 16 Pro Max: 33 h in playback, 29 h in streaming

• iPhone 14/15: 20 h in playback, 16 h in streaming

• iPhone 14/15 Plus: 26 h in playback, 20 h in streaming

• iPhone 14/15 Pro: 23 h in playback, 20 h in streaming

• iPhone 14/15 Pro Max: 29 h in playback, 25 h in streaming

• iPhone 13 mini: 17 h in playback, 13 h in streaming

• iPhone 13: 19 h in playback, 15 h in streaming

• iPhone 13 Pro: 22 h in playback, 20 h in streaming

• iPhone 13 Pro Max: 28 h in playback, 25 h in streaming

• iPhone 12 mini: 15 h in playback, 12 h in streaming

• iPhone 12: 17 h in playback, 11 h in streaming

• iPhone 12 Pro: 17 h in playback, 11 h in streaming

• iPhone 12 Pro Max: 20 h in playback, 12 h in streaming
