iPhone 5 iOS 9.1 Release: 10 Things to Watch For

iOS 9.1 Beta 4 Performance

You'll want to keep a close eye on the iOS 9.1 beta 4 and its performance. 

The features are great but you're really going to want to examine feedback about the update's performance. This way, you'll be a little more prepared for the public release, whenever it arrives. 

One of the best places to track down feedback is YouTube. We're already seeing early feedback emerge and we'll likely see more arrive this week. These videos will give you a feel for how the update is handling ahead of release. 

Do this if you decide not to install the iOS 9.1 beta on your own device.
