iOS 12.4 comes with a series of big increases for iPhone battery life, the Apple company seems to have achieved unexpected improvements for its customers. In the video clip above you can see a performance test regarding the battery life of iPhone phones, and iOS 12.4 is much better than iOS 12.3.1.
iOS 12.4 offers an autonomy of up to 34 minutes of better use compared to iOS 12.3.1, and this means a 10% increase for users. 34 minutes of usage, especially for older iPhone models, is a substantial upgrade in iOS 12.4, and many people will enjoy this change.
iOS 12.4 did not have any changes presented in the list of changes for the battery autonomy of iPhone phones, but here they are, and they are very large. In the video clip above, we haven't tested Apple's latest premium iPhones either, but iOS 12.4 most certainly brings increases in battery life for them as well.
