Apple iOS 9.3 compatible devices: you can install it on iPhone 4s and later, but Night Shift only works on iPhone 5s and newer

Apple has pushed the iOS 9.3 update to all iPhones that got the iOS 9 update, and that means you can install iOS 9.3 on a huge number of compatible devices: 

the iPhone 4s and later, 
the iPod Touch (5th generation) onwards, 
the iPad 2 and newer, 
and the iPad Mini (1st generation) and later.

If you still haven't received the update, make sure to go into Settings > General > Software Update to see if you can manually prop it to install.

And while the list of compatible devices for the iOS 9.3 is huge, not all of the new iOS 9.3 features are coming to all compatible devices. 

The most talked about new feature, Night Shift, a new mode that will shift colors on your screen towards the red to help reduce the sleep-prohibitive blue colors, will only be available on iPhone 5s or later, iPad Pro, iPad Air or later, iPad mini 2 or later, and iPod touch (6th generation). This means that older devices won't get this neat new improvement.

All the rest of the new iOS 9.3 features, however, should work well on older devices like the iPhone 4s, iPhone 5 and iPod touch 5th gen.

9.3 has improved the fluidity of the phone which was already so fluid.Also the night shift could be manually set which is nice.

So does Night Shift actually desaturate the blue pixels within the GPU or just a filter over the screen? Because if it's the latter i don't see why you need a 64bit chip to do it.

I Think its through GPU rendering. Otherwise just rendering the whole color spectrum and having a filter on top of it would hit on the battery. but I might be wrong. Just a guess.

It wouldn't really affect the battery. There is the software method and hardware method and Apple's implementation is the software kind. It will just reduce blue intensity on a pixel before rendering. They're limiting it to newer phones because that's the Apple tax on people with older devices like with Siri.

Video games look freaken awesome in nightshift. It's not like a filter because the clarity is still there, vibrant colors, vivid - but different tone. It does require that the phone is not on low power mode for this, so it makes you wonder how much hardware is dedicated to this.

9.3 is awesome, lag on my iPad Air is gone, spotlight finally works, task switcher is as fluid as ever. I have always had f.lux Installed so night shift isn't a huge deal for me but the speed is. Kudos Apple for great update

Glad you're enjoying the update. I don't get why there isn't Night Shift support for iPhone 5. Right now, I'm stuck with iOS 9 because of jailbreak.

I do have f.lux. And my phone is heavy with tweaks and themes I don't know why people keep saying Android has more customization UI wise.

You're jailbroken right? Exactly. You can do the same with a rooted Android phone and if I recall. You can do much more.

That 4s is a little champ getting latest software. Hopefully, it's not laggy. I still see people using a 4s. Isn't it time for an updated 3.5 inch iPhone? Shrink that SE and call it SJ.
