Apple’s iOS 11.0.3 update is another maintenance update, but it could have a significant impact on your device’s performance. While some of you might want to install the iOS 11.0.3 update today, others might benefit from waiting a few more hours, a few more days or, in some cases, a few weeks.
Many iPhone and iPad users have been dealing with iOS 11 problems in the aftermath of the iOS 11.0, iOS 11.0.2, and iOS 11.0.2 releases and Apple’s new iOS 11.0.3 update fixes a few of these lingering issues including crackling sounds on the iPhone 7 and iPhone 7 Plus and iPhone 6s display issues.
iOS 11.0.3 isn’t as big as iOS 11.0, but the bug fixer could have an enormous impact on the performance of your iPhone, iPad, or iPod touch. This goes for those of you on iOS 11.0, those of you who upgraded to iOS 11.0.1 or iOS 11.0.2, and those looking to move to iOS 11 for the first time.
iOS 11.0.3 is a bug fix update, but it’s 278MB for the iPhone 7. It’s also significant for other iPhones and Apple’s stable of iPads. (276MB for the iPhone SE, 280MB for the iPhone 7 Plus). Your iOS 11.0.3 download will be much larger if you skipped iOS 11.0, iOS 11.0.1, or iOS 11.0.2.
If iOS 11.0.3 starts causing problems you can try dropping back down to iOS 11.0.1 or iOS 11.0.2. Unfortunately, Apple’s permanently closed off iOS 10 and iOS 11.0 and you can’t go back to anything older than iOS 11.0.1.
This move puts even greater importance on your move to iOS 11.0.3, especially if you’re moving your device up from iOS 10. Once you download iOS 11 on your phone or tablet, there’s no going back.
There are plenty of reasons to consider installing iOS 11.0.3 and iOS 11 right now. That said, there are also some reasons why you might be better off holding out. Temporarily, at least.
If you’re on the fence about upgrading your iPhone, iPad or iPod touch to the latest version of iOS, allow us to walk you through the best reasons to and not to install it right now.
Install iOS 11 for Better Security
If the security of your device is important to you you'll probably want to install iOS 11.0.3 today or sometime in the near future.
The iOS 11.0.3 update doesn't come with any new security patches. It simply features the patches from the iOS 11.0 update. (Note: iOS 11.0.1/iOS 11.0.2 didn't come with any new patches either.)
Apple's initial iOS 11.0 update delivered several patches for potential exploits. These patches address serious vulnerabilities in iOS. If you're coming from iOS 10, the iOS 11.0.3 update delivers eight patches to the iPhone, iPad, and iPod touch.
That's not all. iOS 11 also comes with new security features aimed at keeping your data safe. Elcomsoft recently discovered a change to the way iOS deals with trusted devices.
In iOS 11 you can't establish trust with a PC using fingerprints alone. You'll also need to put in a full passcode in order to gain that trust.
If you skipped previous versions of iOS, your iOS 11.0.3 update will come with an even longer list of security patches.
Apple's iOS 10.3.3 update delivered 24 security patches addressing potential issues with Contacts, Messages, Notifications, and Safari. It also included a patch for a potentially dangerous Wi-Fi exploit called "Broadpwn."
If you skipped iOS 10.3.2 you'll get 23 additional patches in iOS 11.0.3. And if for some reason you missed iOS 10.3, you'll get 60 security patches with your version of iOS 11.0.3.
If you want to protect the data you store on your iPhone, iPad, or iPod touch, you should make your move to iOS 11/iOS 11.0.3 soon. This is particularly important for those of you running older versions of iOS.
