It seems to happen every time. Apple releases a new operating system - this time it's iOS 9.3 - and something goes awry. This time, users are frustrated with the much-hyped Night Shift, an app that changes the screen colors at night to reduce the blue light, which in turn is supposed to help you get a better night's sleep.
If you find yourself tossing and turning in bed, though, it might be because you were checking the latest Facebook posts or watching a movie just a little while earlier. Typically, you want to stop using your gadgets one to two hours before hitting the sack, because the blue light it emits fools your body into thinking its daytime.
Apple's Night Shift uses your gadget's GPS and clock to figure out when it's nighttime and changes the screen tint to warmer colors, meaning you will sleep soundly. ... Except that Night Shift doesn't necessarily work the way Apple says it does. For example:
- Night Shift will not work with iPhones made before 2013. That means the iPhone 5 and 5c and the first four generations of the iPad.
- Night Shift will not work in Low Power Mode.
- A display expert told Forbes it's useless, saying "I’ve looked into this before and it’s more of a placebo effect."
Apple has not yet responded to these claims, but regardless, Apple users should still upgrade to iOS 9.3. If anything, you need the security updates. In iOS 9.3 the Notes app is now password-protected and the apps for Health, News, Education and CarPlay also got updates, with significant improvements in Apple Music and Maps.
In order to update your iPhone or iPad, go to Settings>>General>>Software Update.
