Just ahead of Apple’s September event, tomorrow, confirmed regulatory filings reveal that the Apple iPhone 17 range will feature significantly larger batteries. The standout model is the Apple iPhone 17 Pro, which jumps from 3582 mAH in the Apple iPhone 16 Pro to 4252 mAH, marking an 18.7% increase. The new 4252 mAH battery could mean up to four extra hours of daily usage compared to its predecessor. This leap positions the Apple iPhone 17 Pro as potentially offering more longevity than the current Apple iPhone 16 Pro Max.
Pro Max breaks the 5000 mAH barrier
For the first time, an Apple iPhone will exceed 5000 mAH. The Apple iPhone 17 Pro Max reaches 5088 mAH, up 8.6% year-on-year, likely making it the longest-lasting smartphone on the market.
Efficiency improvements with A19 chip
The Apple iPhone 17 series will also benefit from the new A19 chip, built on TSMC’s advanced 3-nanometer process. With no major display changes expected, efficiency gains should further extend battery performance.
Secondary market impact is significant
For the secondary market, larger batteries represent higher residual values. Used Apple iPhones with stronger batteries are easier to resell, as marketplace thresholds often accept 80% to 85% battery health. Fewer replacements mean reduced e-waste and lower costs for refurbishers.
Trade-offs with smaller models
The Apple iPhone 17 Air, designed with a thinner profile, will only feature a 3149 mAH battery, 17% smaller than the standard Apple iPhone 17. While better than early rumors suggested, it remains less competitive for longevity compared to the Pro models.
