According to reports, the battery life of the iPhone 15 series is expected to be longer than previous generations, able to meet users' daily use needs and allowing users to enjoy a longer-lasting battery life experience.

Recently, the entire Internet has been rumored that the battery capacity of Apple’s iPhone 15 series is twice that previously expected.

What is the expected battery life of the iPhone 15 series? Is the battery life of the iPhone 15 series really that great?

Apple updated its support document yesterday, which states that the batteries of Apple iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max have been tested 1,000 times under ideal conditions. After a charging cycle, it still retains 80% of its original capacity.
