Apple recently confirmed an iPhone 6 iOS 9.3 update and it's poised to bring a long list of changes to the former flagship. Today, we want to take a look at a few things iPhone 6 users need to know about their upcoming iOS 9.3 release.

The iPhone 6 is currently on Apple's iOS 9.2.1 update but it won't stay on iOS 9.2.1 forever. Apple's got at least one more big iOS 9 update up its sleeve before it debuts and releases the rumored iOS 10 update for iPhone, iPad and iPod touch.

That update? iOS 9.3.

The iOS 9.3 update is very real and it's heading for the iPhone 6 (and iPhone 6 Plus) at some point down the road. Like the iOS 9.1 and iOS 9.2 milestone update's before it, it's going to be a big one for Apple's original 4.7-inch smartphone.

With an iPhone 6 iOS 9.3 release date inching closer, we want to outline five things you should know, right now, about the iPhone 6 iOS 9.3 update, its highly anticipated release date, and more.

It's still early but we already have a few details regarding the iPhone 6 iOS 9.3 update's performance, features, and more. Here's what you need to know right now.

iPhone 6 iOS 9.3 Performance So Far

Now that the iOS 9.3 beta is progressing, we're starting to get a better feel for the iPhone 6 iOS 9.3 update's performance.

It's still early but the iPhone 6 iOS 9.3 update seems to be holding up quite well in the third version of Apple's beta. 

iPhone 6 iOS 9.3 beta 3 users report that "app load times greatly improved" and that "tapping apps is almost as smooth as iOS 8." We haven't had any major issues with app load times on iOS 9.2.1 but it appears some people have. 

iOS 9.3 beta users are also reporting improvements to the performance of the News application. The app reportedly refreshes "articles and performs much faster." 

If don't plan on trying the iOS 9.3 update early, it would be smart to keep an eye on this feedback as the iOS 9.3 update progresses through the beta. This way, you'll get a feel for the iOS 9.3 update's features and performance ahead of time. 

If you want to try the iPhone 6 iOS 9.3 update right now, you can.

In January, after a short delay, Apple released a public version of the iOS 9.3 update in beta form. The update is available to anyone with a working Apple ID through the Beta Software Program. 

It's a tempting update but remember that early iOS software isn't for everyone. We've put together a list of reasons to try and some reasons to avoid the first iOS 9.3 beta and any upcoming iOS 9.3 betas that Apple releases. 

If you do decide to try the iPhone 6 iOS 9.3 beta, you'll want to take a look at our list of pre-installation tips. They will guide you through the process we typically use. 

Remember, you can always downgrade to iOS 9.2.1 if you decide that you don't like iOS 9.3 and its performance.

You can't downgrade to anything older than that though so if you're on iOS 9.2 or below, you'll want to be sure that the iOS 9.3 beta is right for you.
