Apple found that a lot of people were using their smartphones before going to bed, and apparently, white light is very bad for one's eyes in the dark. The blue light filter feature was introduced by Apple for users using their phones at night. Warmer colours are easier on the eyes, helping users avoid eye strain and the splitting headaches that follow. But it turns out that the 'Night Shift' mode has its fair share of limitations which Apple obviously didn't mention during the launch of the updated iOS. Also, according to one of the most sought-after display testers in the industry, the night shift does not fit the standards for a purposeful screen.

There's the compatibility issue

Like any other fanboy, I was pretty excited about the 'Night Shift' mode but as it turned out, the mode wasn't available for my iPhone 5. I agree, with the iPhone 7 set to launch in September, my phone has become pretty slow and doesn't have the processing power required to do most things in vogue. But the thing is, 'Night Shift' practically requires no processing power at all! So that means, iPhone 5, iPhone 5c, the first four generations of iPad and a lot of iPods aren't included in the update. To put it simply, any iPhone, iPad or iPod manufactured before 2014 will not have the update.

This is because Apple decided to code the Night Shift exclusively in 64bit code and devices not using the Apple A7 chipset or newer become incompatible. A very convenient and boringly predictable way of Apple asking you to move on to their newer products.

Low battery? Too bad for you

Even if you look beyond the incredibly annoying compatibility issue, another problem that's been making people talk is its incapability of working in low power mode. It really doesn't add up, does it? The Night Shift mode, since it uses one standard tone of colour, should be drawing less power from the iPhone anyway. Secondly, Night Shift mode is supposed to be used in the night, the time when most are more likely to be running on low power. So why should the battery have any influence on Night Shift?
