The official version battery life test of iOS 18 and 17.7 is here. Which one should I choose?

In the middle of this month, Apple released the official versions of iOS 18 and iOS 17.7. iOS 18 has added many new features, but many friends are hesitant to upgrade, worrying about the battery life after the upgrade.

Now, foreign blogger iAppleBytes has brought us the battery life tests of the two official versions of iOS 18 and iOS 17.7. Let’s take a look!

The testing method is the same as before. iAppleBytes found six iPhone models, namely iPhone SE 2020, iPhone XR, iPhone 11, iPhone 12, iPhone 13, iPhone 15, etc.

iAppleBytes still uses the battery testing function provided by the GeekBench tool to compare the running scores and automatic shutdown time of six iPhones after upgrading to iOS 18 and iOS 17.7 systems respectively.

Before the test, the screen brightness of each phone was adjusted to 25%, and the automatic brightness adjustment function was turned off (maintaining the same settings as when testing previous iOS versions). The battery health was basically maintained above 90%. Each iPhone ran GeekBench from a full charge until it automatically shut down.

The test results are as follows:

Compared with iOS 17.6.1, the battery life of various iPhones when running iOS 17.7 is not much different, and they are basically in a stable state. The results of iOS 18 show that the battery life of new models is even worse than that of iOS 17.7, especially the iPhone 15, which lags behind by 20 minutes.

On the contrary, the battery life of the two long-lasting models, iPhone XR and iPhone 12, has been improved after upgrading to iOS 18.

However, it should be noted that the test results of GeekBench are different from actual daily use, so these data are for reference only. In fact, every time Apple updates a version, users will have different opinions on battery life. After all, everyone's usage is different.

Friends who have upgraded to the official versions of iOS 18 or iOS 17.7, how are you using them now? You can share your experience in the comment section!
