iPhone 5s iOS 9.3 Update: 5 Important Details

You Will Get Night Shift

The iOS 9.3 update is coming with a feature called Night Shift. Night Shift is similar to F.lux for Mac in that it reduces the amount of blue light coming from your display in an effort to help you sleep better at night.

Night Shift is arguably the most exciting feature coming with iOS 9.3 but it's not going to be available for every single iPhone model. Only some names are making the cut. 

The iPhone 5 won't get Night Shift but the iPhone 5s will be getting Night Shift with iOS 9.3. That's a huge relief for those of you still holding onto the iPhone 5s because it means that you won't have to jailbreak your device to get the feature. 

If you want to get a feel for the Night Shift feature ahead of the iOS 9.3 release date, take a look at F.lux for Mac.
