Apple hasn't revealed specific battery capacities, but latest info suggests there's no improvement in battery life for the iPhone 15 series.
Early this morning (9/13), Apple officially unveiled its new iPhone lineup, including the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. Despite notable upgrades, the iPhone 15 series might leave many feeling underwhelmed, especially regarding battery life.

According to figures released by Apple, the battery life on the iPhone 15 lineup - both the Pro and standard models, remains unchanged from the previous generation. Additionally, these phones only support 20W wired fast charging, similar to the iPhone 14 lineup.

Therefore, to know the exact battery capacity of the iPhone 15 series, we'll have to wait until these products are widely released and someone 'opens up' to investigate.


In reality, if Apple has altered the battery capacity of the iPhone 15 lineup, it's likely they've made them smaller. The iPhone 15 and 15 Plus come with the A16 Bionic processor, while the iPhone 15 Pro and 15 Pro Max are equipped with the entirely new A17 Pro 3nm chip.

Apple has spent quite some time emphasizing that these chipsets are more power-efficient than previous generation models. So why does the battery life of the iPhone 15 resemble that of the iPhone 14 from 2022? Clearly, the most reasonable answer is that the iPhone 15 series has a smaller battery capacity (in mAh) compared to its predecessor generation.
