Apple released iOS 12.1.4 last week, primarily to fix the Group FaceTime bug. We have often seen interim updates increase iPhones’ battery life due to optimizations and other tweaks. However, the opposite can also happen, so the YouTube channel iAppleBytes carried out the iOS 12.1.4 battery life test to find out whether the latest iOS update has affected battery life.

iOS 12.1.4 Battery Life Test Shows Marginal or No Improvement

iAppleBytes conducted the popular Geekbench battery life benchmark test on an iPhone 5s, iPhone 6, iPhone 6s, iPhone 7 and iPhone 8 running on the latest version of iOS. The channel regularly performs this test on the latest version, and whenever the next one is released, it runs the tests again and releases an update.

After performing the iOS 12.1.4 battery life test, iAppleBytes compared the results with those from the iOS 12.1.3 test. Overall, the iOS 12.1.4 battery life test showed a very marginal improvement over the previous version of iOS. The biggest gainer was the iPhone 8, which gained six minutes after updating to iOS 12.1.4. However, that’s not a big gain when you consider how long it takes the entire battery to drain.

You can see the comparison video in its entirety here:

It makes sense that there would be no improvement or a very marginal one, considering the lack of feature-related changes between the two iOS releases. Speed test videos for iOS 12.1.4 yielded similar results as well, indicating no major changes in the speeds between the two versions.

The speed and battery life tests essentially verify that the iOS 12.1.4 update contains only bug fixes. Apple is expected to release iOS 12.2 later this month or in early March, so hopefully we will see some battery improvements then.

Fixes a Few Bugs, but Triggers More for Some

Apple’s iOS 12.1.4 update addresses the Group FaceTime bug, which captured many headlines last week. The issue with FaceTime allowed users to eavesdrop on others even when their call was not answered. In other words, the caller could hear everything on the other line just by calling, even if the receiver had not accepted the call.

Apple was widely criticized for the bug. To ensure that the issue causes no further problems, Apple disabled the feature for everyone at the time. Now the latest update re-enables the feature for all.
