Apple’s new iOS 11.0.3 update is a pretty sizable download, but it shouldn’t take you too long if you’re prepared.
iOS 11.0.2’s been replaced by a brand new iOS 11.0.3 update. iOS 11.0.3 is another bug fix update focused on fixing iOS 11 problems and it’s a fairly sizable download for iOS 11 users.
If you’re upgrading to iOS 11.0.3 from iOS 10.3.3 or an older version, your iOS 11.0.3 update could be over 2GB. If you’re moving to iOS 11.0.3 from iOS 11.o.2, you’re looking at a 278MB download if you own an iPhone 7.
Download sizes will vary based on device and the version of iOS running on your device. iOS 11.0.2 users will see the smallest iOS 11.0.3 download while those coming from older versions of iOS will see a larger update and longer download times. This is because the features and fixes from iOS updates you skipped are baked into iOS 11.0.3.
While some of you might want to hold off on a download today, others are perfectly fine upgrading from iOS 10 (or whatever you’re currently running) to iOS 11.0.3
If you do decide to download iOS 11/iOS 11.0.3 onto your device you’ll want to set aside some quiet time to get the job done. Making the transition from one iOS operating system to another can cause problems so make sure you take your time with the new firmware.
We can’t tell you exactly how long your iOS 11.0.3/iOS 11 update will take because download times always vary from person-to-person, device-to-device.
That said, we can help you approximate how much time to set aside if and when you decide to download the iOS 11 update to your iPhone, iPad, or iPod touch for the first time. We can also help those of you transitioning from iOS 11.0/iOS 11.0.1/iOS 11.0.2 to iOS 11.0.3.
If you’ve prepared for iOS 11 and iOS 11.0.3 and you’re connected to a fast Wi-Fi network, moving from iOS 10 to iOS 11 for the first time could take you less than 20 minutes to complete. If you haven’t done any prep work, the process could take a whole lot longer.
|Sync (Optional)||5-45 minutes|
|Backup and Transfer (Optional)||1-30 minutes|
|iOS 11 Download||15 Minutes to 2 Hours|
|iOS 11 Update||15-30 Minutes|
|Total iOS 11 Update Time||30 minutes to 2 Hours|
Prepare for iOS 11
If you’re planning to install iOS 11 you’ll want to set aside some time time to prepare yourself, and your device, for the move. A little prep ahead of an install can help to prevent problems and major headaches.
To assist, we’ve put together a guide that will take you step-by-step through the process we take before we install iOS updates on our devices.
These steps could take you a few minutes or they could take you much longer depending on the state of your device and your skill level.
If you haven’t made a proper backup, checked in with your IT department, or dug into the changes in the iOS 11 update, the pre-installation process could take you an hour or more.
You don’t need to follow every step, but make sure you backup your most important files. You’ll want to keep those safe as you move from your version of iOS to iOS 11.
Even if you’re just moving from iOS 11.0/iOS 11.0.1/iOS 11.0.2 to iOS 11.0.3 you’ll still want to spend some time prepping yourself, and your device, for the move.
iOS 11 Download Time
Once you’ve properly prepared it’ll be time to initiate the iOS 11 download. The exact iOS 11 download size will, again, depend on your device and current version of iOS. The iOS 11 download time will depend on your connection.
If you’re coming from iOS 10, the iOS 11 download could be over 2GB. It’s a substantial download, but it shouldn’t take you too long provided you’re connected to a high speed network. If you’re connected to high speed Wi-Fi your iOS 11 download should only take a few minutes.
If you’re coming to iOS 11 from an older version of iOS, expect your download to be bigger due to the updates you missed along the way. This will also increase the download time.
If you’re moving from iOS 11.0, iOS 11.0.1, or iOS 11.0.2 to iOS 11.0.3, you can expect a smaller download and a shorter download time.
Our iPhone 7’s iOS 11.0.3 download, a 278MB file, took just a minute to complete.
iOS 11 Installation Time
Once you’ve successfully downloaded iOS 11 from Apple’s servers the update will need to install on your device. This could take awhile depending on your device and situation.
The iOS 11 installation process could take upwards of 10 minutes to complete if you’re coming from Apple’s iOS 10.3.3 update.
If you’re coming from something older, your installation could take 15 minutes or longer depending on the version of iOS you’re running.
Your phone or tablet might reboot itself a couple of times as the installation starts finishing up so don’t be alarmed. This is normal.
If you are moving from iOS 11.0/iOS 11.0.1/iOS 11.0.2 to iOS 11.0.3 you can expect a shorter installation time. Our iPhone 7 completed the installation in about five minutes.
Once your installation finishes up you might think your work is done. It’s not.
After the installation is complete you might need to spend time logging into iCloud and various apps and services. iOS updates will sometimes log you out.
You’ll want to spend time checking your important data (photos, music, etc) to ensure that it’s all still there. We also recommend testing your core apps and services to ensure that they’re agreeable with iOS 11 and iOS 11.0.3.
You should also poke around for bugs and monitor your device’s performance (battery life, Wi-Fi and Bluetooth connectivity, etc).
If you do run into a problem with Apple’s new update, take a look at our list of fixes for common iOS 11 problems. You might find what you’re looking for there.
Install iOS 11.3 for Better Security
iOS 11.3 also includes a new privacy feature. When an Apple feature wants to use your personal information, an icon now appears with a link to access detailed information about how your data will be used and protected.
If you're running iOS 11.2.5 or older, you're exposed to an issue that lets people send a specific character that will crash an iOS-powered device and block access to the Messages app. It can also block apps like Facebook Messenger, Gmail, Outlook, and WhatsApp.
The iOS 11.2.6 update's main purpose was to patch up this issue. If you skipped iOS 11.2.6, you'll get these enhancements with iOS 11.3.
If you're running iOS 11.2.2 or below and receive a certain GitHub link through your Messages app, your iPhone or iPad can lockup or respring. The Messages app will also become unusable.
If you're on iOS 11.2.1, your iOS 11.3 update includes security improvements to Safari and WebKit to mitigate the effects of Spectre. If you're running an older version of iOS, your iOS 11.3 update will come with a lot more.
Apple's iOS 11.2 update fixed several problems, but it also brought problems of its own including a potentially nasty zero-day iOS HomeKit vulnerability.
The vulnerability, discovered by Tian Zhang, allowed for unauthorized control of HomeKit accessories including garage door openers and smart locks.
Apple quickly rolled out a server-side fix, but the company restored full functionality with the release of iOS 11.2.1. If you skipped iOS 11.2.1 and use HomeKit, you should download iOS 11.3.
If you skipped iOS 11.2, you'll get a few more patches with your iOS 11.3 update. Apple's iOS 11.2 update delivered 11 patches including one for Mail and one for Wi-Fi.
The iOS 11.2 and iOS 11.2.1 updates also patched up a widespread security issue called "Meltdown." Apple says its analysis suggests it "has the most potential to be exploited."
Meltdown affects all iOS 11 powered devices so we highly recommend downloading iOS 11.3 if you skipped iOS 11.2.
If you skipped iOS 11.1.2, iOS 11.1.1, and iOS 11.1, you'll get additional patches with your iOS 11.3 update.
The iOS 11.1 update delivered eight security patches including a fix for a serious Wi-Fi vulnerability called KRACK or Key Reinstallation Attack. KRACK is an exploit that targets the common WPA2 encryption protocol.
If you're just now making to move from iOS 10 (or whatever you're on) to iOS 11, your iOS 11.3 update will come with additional security features.
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 older versions of iOS, your iOS 11.3 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 with iOS 11.3. And if for some reason you missed iOS 10.3, you'll get 60 security patches with your iOS 11.3 update.
If you want to protect the data you store on your iPhone, iPad, or iPod touch, you should make your move to iOS 11 and iOS 11.3 soon.
This is particularly important for those of you running older versions of iOS.
