Probably the most welcomed feature announced for the iPhone 13 is a bigger battery. Apple didn't share the size, but claims that the new battery along with iOS 15, the A15 chip and updated display adds 2.5 hours of battery life to the iPhone 13 (compared to the iPhone 12).  The iPhone 13 Mini should get an 1.5 hours more than the iPhone 12 Mini. That's a significant increase: The battery life on the iPhone 12 Mini was a compromise some people weren't willing to make. So it's exciting to see the new Mini get such a big bump in just a year. Apple says that the Pro models should see a similar increase in battery life with the iPhone 13 Pro getting 2.5 hours more and the 13 Pro Max getting an additional 1.5 hours.
