IAppleBytes has released a video measuring battery life on an iPhone with iOS 15.0.2 installed. The test results of iPhone 13 are also released. Many models of iPhones tested tend to have a modest improvement in battery life.
Do you have a battery with iOS 15.0.2 that fixes bugs and vulnerabilities?
Released on October 11, local time, iOS 15.0.2 addresses multiple bugs and fixes serious vulnerabilities.
The battery capacity of the iPhone that installs iOS 15.0.2 and measures the battery life is as follows compared to when it was new.
- iPhone SE (1st generation): 97%
- iPhone6s: 100%
- iPhone7: 100%
- iPhone8: 99%
- iPhone XR: 92%
- iPhone11: 100%
- iPhone SE (2nd generation): 88%
- iPhone13: 100%
In conducting the test, we turned off the automatic adjustment of the display brightness, unified the brightness to 25%, and performed the battery test of the benchmark test application Geekbench 4.

The time it took to reach zero battery and the battery test score by GeekBench 4 are as follows.

In addition, since the test of iPhone SE (2nd generation) ended in the middle, valid data has not been obtained.
Battery score of iPhone 13 is outstanding, each model is improving
Here is a graph that lists the battery scores of successive iOS versions by iPhone model. The score of iPhone 13 is outstanding.
Here are the scores for iPhone SE and iPhone 6s. The iPhone SE is slightly improved in iOS 15.0.2, and the iPhone 6s is flat.
Here are the scores for iPhone 7 and iPhone 8. The iPhone 7 has a slightly lower score on iOS 15.0.2, and the iPhone 8 has improved slightly.
Here are the scores for iPhone XR and iPhone 11. Improvements can be seen on both iPhone XR and iPhone 11.
Here are the scores for iPhone SE (2nd generation) and iPhone 13. The iPhone SE (2nd generation) was not compared because the test ended in the middle, and the iPhone 13 has further improved the score from iOS 15.0.1.
iOS 15.0.2 is also promising from a battery perspective
Regarding the test results, iApple Bytes evaluated that iOS 15.0.2 is a promising version from the viewpoint of battery life as the battery life has improved in each model except for a slight score drop in iPhone 7. doing.
For the iPhone SE (2nd generation), which encountered the first situation where the test was forcibly terminated in the middle, the test was terminated halfway because the maximum battery capacity was reduced from 90% until iOS 15.0.1 to 88% compared to when it was new. While questioning whether it is, he said he would consider replacing the battery or replacing it with the iPhone 12.
