iPhone 4s iOS 9.1 Problems
iOS 9.1 problems continue to plague the iPhone 4s.
Over the past two weeks, we've been monitoring complaints about iPhone 4s users. iPhone 4s iOS 9.1 problems include issues with lag and slowdown, problems with battery life, issues with Wi-Fi and Bluetooth connectivity, problems with various applications, problems with Apple Music, and more.
Most of these problems are affecting a tiny fraction of iPhone 4s owners though there are a few (the lag issues, for instance) that are a little more widespread.
These problems are why we recommend doing a little prep work ahead of your install. You can't predict if you'll see issues so you'll want to be extremely careful with iOS 9.1 and your device. For more on iOS 9.1 problems, head here.
