Recent rumors suggest that the upcoming iPhone 15 lineup will feature significantly larger batteries across all models, potentially resulting in longer battery life compared to the iPhone 14 series. According to an alleged Foxconn worker speaking to ITHome, the iPhone 15 is said to have an 18% larger battery, the iPhone 15 Plus and iPhone 15 Pro a 14% larger battery, and the iPhone 15 Pro Max a 12% larger battery.

Here are the rumored battery capacities for each iPhone 15 model:

iPhone 15: 3,877mAh (vs 3,279mAh on iPhone 14)
iPhone 15 Plus: 4,912mAh (vs 4,325mAh on iPhone 14 Plus)
iPhone 15 Pro: 3,650mAh (vs 3,200mAh on iPhone 14 Pro)
iPhone 15 Pro Max: 4,852mAh (vs 4,323mAh on iPhone 14 Pro Max)

While this is the first battery-related rumor for the iPhone 15 lineup, it aligns with expectations given the efficiency improvements typically associated with Apple’s new chipsets. The iPhone 15 and iPhone 15 Plus are rumored to inherit the A16 Bionic chip from the iPhone 14 Pro and iPhone 14 Pro Max, while the iPhone 15 Pro and iPhone 15 Pro Max are likely to feature the more efficient A17 Bionic chip.
