As Apple‘s biggest system update this year, iOS 15.4 has attracted the attention of many fruit fans. Many people upgraded iOS 15.4 for the first time, hoping to enjoy the excellent experience brought by the new system earlier.

The part of the fruit fans who have not been upgraded is estimated to be frightened by the battery life of iOS 15.4. Has the battery life of iOS 15.4 really rolled over? Is iOS 15.4 worth upgrading? We can look at the actual test of the iPhone‘s battery life that supports upgrading to iOS15.4 and then come to a conclusion.

For comparison, let’s first look at the battery life of the major iPhones in the iOS15.3 system:

The first generation of iPhone SE has a total battery life of 2 hours and 47 minutes;

iPhone6s: 2 hours and 29 minutes of total battery life;

iPhone13: The total battery life is 8 hours and 13 minutes;

After reading the battery life performance of the major iPhones in iOS15.3, let‘s take a look at their performance in iOS15.4:

iPhone SE first generation: total battery life of 2 hours and 52 minutes;

iPhone6s: total battery life of 3 hours and 13 minutes;

iPhone7: Total battery life is 3 hours and 33 minutes;

iPhone SE 2nd Generation: Total battery life is 3 hours and 48 minutes.

Comparing the battery life of iOS 15.3 and iOS 15.4, iOS 15.4 did not cause a significant drop in battery life. Although some models did experience a 5-15 minute battery life shortening, they did not drop by 50 minutes as claimed on the Internet. % is such an exaggeration. On the other hand, the battery life of the iPhone 6s, iPhone 12, iPhone 13 and iPhone SE 2 increased by an average of 10-30 minutes after upgrading to iOS 15.4.

In response to the problem of crazy power failure, Apple also responded accordingly: iOS 15.4 brings a lot of new features, within 48 hours after installing the new system, the application and mobile phone functions need to be adjusted, and the battery life changes. is normal. You can use it for a while, and if you have any questions, you can contact the official website at any time.

Apple‘s explanation is not unreasonable. Many mobile phones need to perform a lot of read and write operations and function adjustments in the first few days after updating the new system. Therefore, the power consumption will increase significantly in the first few days. After the adjustment of the functions of the mobile phone is completed, the battery life will return to normal.

At least in the big picture, iOS 15.4 is still great and well worth the upgrade.
