In an unusual turn of events in the smartphone world recently, it appears that the battery life of the iPhone 15 is actually better than Apple had originally claimed

It is rare for details of a device to change after launch, especially if the changes are dramatic However, the battery life of the iPhone 15 appears to be more than double what was originally claimed, although Apple has yet to mention what caused this change to occur

According to a report by 9to5Mac, Apple has retested the iPhone 15 and iPhone 15 Pro (and 15 Plus and 15 Pro Max) batteries and now claims they can maintain at least 80% of their original capacity after 1,000 charge cycles

We tested the iPhone 15 series batteries and found that both the iPhone 15 Plus and iPhone 15 Pro Max are on our Best Smartphone Battery Life list, and all last relatively very long

When Apple mentions charging cycles, it means charging the phone to 100% and then letting it naturally drain to 0% The battery naturally decays over time, reducing the amount of charge it can hold, even though the phone shows 100% In other words, the more time that passes, the longer the phone will be out of service However, battery testing is difficult and rarely yields a concrete answer, as many factors can change the results

The main question now is how and why this occurred Apple has yet to comment, so we do not know if the battery is simply better than originally announced, or if Apple has changed the way it tests its batteries Apple has had some issues with battery life in the past For example, iPhone 14 users noticed that their phones' batteries were losing health after less than a year of use, and the infamous "Battery Gate" controversy, which was settled this year

However, this remains great news for those who want to keep using their iPhone as long as possible before upgrading
