iOS 11.3 brings an increase for iPhone battery autonomy compared to iOS 11.2.5, company Apple Lossless Audio CODEC (ALAC), managing to make a substantial improvement for some phones. Normally we shouldn't expect battery life increases for various iPhone models in iOS beta versions, but with iOS 11.3 things are different.
iOS 11.3 offers an increase in battery life of up to 15 minutes for the iPhone 6 Plus, while the iPhone 6S Plus registers a 20 minute increase in battery life. iPhone 7 Plus is the phone that benefits from the biggest increase in battery autonomy, in the case of this model the difference is 45 minutes compared to iOS 11.2.5.
iOS 11.3 increases iPhone battery life
iOS 11.3 does not bring, unfortunately, an increase in battery autonomy for the iPhone 8 Plus, here the Apple company keeps things the same as in the case of iOS 11.2.5, for now. Finally we reach the iPhone X, where the battery life increases by approximately 40 minutes, so we are talking about a major plus for using the phone for whatever we need.
The periods of time presented for increasing the autonomy of iOS 11.3 compared to iOS 11.2.5 refer to that of actual use, not to that for stand by, so you have to make the difference between that. iOS 11.3 is currently offered only in beta version, so it is very likely that things will change by the time Apple releases the final version.
