While the wait for the iPhone 15 series continues, information about new models continues to come. It looks like the iPhone 15 models will have a significantly larger battery capacity than the current iPhone 14 models. Considering the developments in production technology, the iPhone 15 seems to be strong in battery life.

According to a Foxconn employee who spoke to ITHome, the iPhone 15 will have a battery 18 percent larger, the iPhone 15 Plus and iPhone 15 Pro 14 percent, and the iPhone 15 Pro Max 12 percent larger. If true, these changes mean that the iPhone 15 Plus will further increase its battery capacity lead over the Pro Max model, while the iPhone 15 Pro will remain the iPhone with the smallest battery.

iPhone 14: 3,279mAh iPhone 15: 3,877mAh

iPhone 14 Plus: 4,325mAh iPhone 15 Plus: 4,912mAh

iPhone 14 Pro: 3,200mAh iPhone 15 Pro: 3,650mAh

iPhone 14 Pro Max: 4,323mAh iPhone 15 Pro Max: 4,852mAh

The credibility of these claims is uncertain, but the claimed capacities seem reasonable, especially given the fact that this year's iPhone models are expected to be slightly thicker, providing more internal space for larger batteries. Along with the efficiency improvements of the Apple A16 and A17 Bionic chips, it seems highly likely that the entire iPhone lineup will have battery life improvements this year.

ITHome also says that the iPhone 15 Pro, allegedly from Foxconn and circulating on Weibo, will be offered for sale with 256GB of storage as standard. It should also be noted that the basic capacity in the current models is 128GB. This will also be an important distinction between the Pro and non-Pro models, as the iPhone 15 and iPhone 15 Plus are still expected to have 128GB of storage.
