Apple released an update to its mobile software platform last week. As it turned out, iOS 17.1.1 not only fixed unpleasant crashes, but also introduced new ones.

Thematic resource iAppleBytes published a video in which five different iPhone models were tested with iOS 16.7, iOS 17.1 and iOS 17.1.1 installed. As a result, they found that iOS 17.1.1 reduced battery life. There was a decrease of 14-18 minutes on iPhone XR and iPhone 12, and 44 and 52 minutes on iPhone 11 and 13.

Users who installed the update complain about the battery draining very quickly on the network. He points out that smartphones sell out in just a few hours. There are also complaints about overheating. Here are some similar reviews:

iOS 17.1.1’s battery life sucks!

However, as ZDNet points out, installing a new operating system on an iPhone runs many processes in the background, from indexing to recalibrating the battery, and this process can take hours or even days. As a result, all this may give the impression that the battery is draining faster, when in reality it is not.
