Here’s how iPhone 17 Air battery could stack up against previous iPhones

A new leak over the weekend has revealed what appears to be battery capacities for every new iPhone 17 model, including the ultra-thin iPhone 17 Air. Here’s how the reported iPhone 17 Air battery capacity stacks up against previous iPhone models.

Leaked iPhone 17 Air battery capacity vs. prior iPhone models

iPhone 17 Air will be the flashiest new model this year, with its ultra-thin design offering something fresh after years of more ‘boring’ updates.

Battery life has long been the biggest question mark with the model, but now the battery capacity has apparently leaked.

iPhone 17 Air will have a 3,149mAh battery, per leaked specs.

This compares to the iPhone 17’s 3,692, 17 Pro’s 4,252, and 17 Pro Max’s 5,088.

Battery capacity is far from the only factor that determines overall battery performance. But it can still give us a helpful ballpark of what to expect.

Here’s how the 17 Air’s 3,149mAh number compares to prior iPhones:

iPhone 17 Air will have a 6.6-inch display—a size that has never previously existed for the iPhone.

Apple’s Plus models are the closest equivalents with 6.7-inch displays.

However, iPhone 17 Air will include ProMotion support with a variable 120Hz refresh rate. That’s something the Plus line never had—making direct comparisons tough. The 6.3-inch iPhone 16 Pro might be a helpful second reference point.

It will be interesting to see how much Apple talks about the iPhone 17 Air’s battery in its presentation. My guess is that they’ll make a vague reference to “great all-day battery life” without specifics. But we’ll soon find out.

How are you feeling about iPhone 17 Air’s battery after seeing how this comparison? Let us know in the comments.
