iOS 11.0.2 destroys the autonomy of the iPhone battery, according to a test published yesterday and made in comparison with iOS 11.0.1 on 8 iPhone Plus and iPhone 7 Plus. According to this test, iOS 11.0.2 reduces the autonomy of the iPhone 8 Plus battery by up to 3 hours compared to 11.0.1, the difference being huge, especially since the phone has a 2700 mAh battery integrated by Apple.
iOS 11.0.2 makes the iPhone 8 Plus inferior to the iPhone 7 Plus in terms of battery life, although in iOS 11.0.1 the new iPhone model was superior to the one released last fall. The difference in iOS 11.0.1 between the two phones is over an hour in terms of battery life, in favor of the iPhone 8 Plus, but here's how Apple managed to destroy something good with a change that it didn't say much about.
iOS 11.0.2 destroys iPhone battery life
iOS 11.0.2 also has a bug regarding the display of the iPhone's battery autonomy, which decreases during fast charging and freezes during normal charging. It's hard to say if this bug of iOS 11.0.2 also greatly affects the battery life of the iPhone 8 Plus, probably including that of the iPhone 8, but it is very possible, so it is advisable to avoid this version of the operating system.
iOS 11.0.2 was released by Apple to solve a problem that generates static sounds during phone calls on iPhone 8 and iPhone 8 plus, but it causes other annoying problems. Unfortunately, we will have to wait for the release of iOS 11.0.3 to be able to update from iOS 11.0.1 on iPhone 8 and iPhone 8 Plus, or you can upgrade to iOS 11.1 beta, which has excellent autonomy and performance to measure.
iOS 11.0.2 seems to negatively affect only the battery life of the iPhone 8 and iPhone 8 Plus, but it is possible that other models are also affected.
UPDATED: And a second video clip that confirms the fact that the autonomy of iOS 11.0.2 is worse than iOS 11.0.1, but without a test on the iPhone 8 Plus.
