1. Make a backup of your device

There're 3 common ways to perform this task:

Method 1. Back up with iCloud: stay connected to WiFi until backup finishes -> Settings -> iCloud -> Backup -> turn on iCloud Backup -> hit Back Up Now. Once completed, you'd better go to Storage to check whether the backup is ok.

Method 2. Back up via iTunes: connect your device to computer and launch iTunes -> select your device in iTunes -> select Summary from the left sidebar -> tap on Back Up Now and click Done when it is finished.

Method 3. Backup data via third-party software like WinX MediaTrans. This tool is a top-notch iOS file manager and also an ace iTunes alternative, capable of backing up iDevice photos, music, videos, eBooks, iTunes purchased music/movies/audio books, and more to computer and other storage devices.

2. Free up space if necessary

iOS 11 update requires between 1GB and 2GB of free space on your device. So, make sure you have enough space. If your space is limited, you can delete some useless content or apps or take other measures to clean up your iPhone iPad iPod.

3. Make sure your battery is enough

Your battery is supposed to be at least 60% charged to ensure the whole iOS 11 update. To be on the safe side, keep plugging in the power supply until update is finished.

4. Connect to WiFi

WiFi connection is required if you choose to process iOS 11 update wirelessly on your iOS device. If you've some troubles about WiFi connection, check how to fix iPhone not connecting to WiFi.

Then, we come to the steps to update to iOS 11. Two methods are available for you.

update to iOS 11 over the air

Method 1. Download and install iOS 11 on your iPhone iPad iPod over the air

Step 1. Open Settings, tap on General, and then click Software Update. And then your device will check for new updates immediately, and will display the latest iOS version available for your device with detailed introduction and the amount of storage space required.

Step 2. Hit Download and Install at the bottom, if iOS 11 is ready. Download time depends on WiFi speed and the amount of traffic Apple's servers are seeing. After downloading iOS 11, you can update now by taping Install, or update later by taping Later or choosing Install Tonight or Remind Me Later. Do remember to plug in power before going to bed if you opt for installing tonight. If iOS 11 doesn't show up, it means that iOS 11 isn't available now or not supported by your device.

Note: Over the air update isn't suitable for jailbroken iPhone.

download and update iOS 11 with iTunes

Method 2. Update to iOS 11 using iTunes

If you can't update to iOS 11 wirelessly for certain reason, such as WiFi is not working and you have a jailbroken iPhone, iTunes is the way to go.

Step 1. Connect your iPhone iPad or iPod to a computer via USB cable. And make sure the computer has installed the latest version of iTunes.

Step 2. Launch iTunes, and select your device.

Step 3. Click Summary located at the left column and then hit Check for Update. Then, choose Download and Update, and tick Agree to confirm. If you're required to enter passcode, just do it.

iOS 11 Update Guide: How to Fix Errors While/After Upgrading to iOS 11?

Here we will list top 5 common iOS 11 update errors and throw out corresponding solutions.

unable to check for update when updating to iOS 11

1. Unable to Check for Update/Unable to Verify Update

When we update to iOS 11 over the air, we may see one of the following error messages:
"Unable to Check for Update. An error occurred checking for a software update."
"Unable to Verify Update. iOS failed verification because you are no longer connected to the Internet."

Solution: Click "Try Again" or "Retry" under the same network. If it doesn't work, you should connect your device to a different network, and try again. If this error still occurs, you're suggested to remove the update file and download it again. To remove it, you should do as follows: tap on Settings -> General -> Storage & iCloud Usage -> Manage Storage -> Find the iOS update, tap it and click Delete.

iOS 11 update OTA doesn't complete error

2. iOS 11 update OTA doesn't complete

Update requires quite a long time especially when your network is slow, your device has a number of files, and lots of people are doing update. But if the update never completes and the progress bar stays the same point for a very long time, you need to take some measures.

Solution: Turn off your device and later restart it to let the update complete.

iOS 11 Software Update Failed

3. Software Update Failed

One of the most common iOS 11 update problems when updating over the air is "Software Update Failed". People will see a message like below:
"Software Update Failed. An error occurred downloading iOS 11"

1. Try again after a few hours or longer time. Apple servers will bear the huge amount of traffic once the new iOS 11 is released. Thus, servers may fail to respond to some requests successfully. So, wait for some time and try again when there's less traffic.
2. Abandon over the air update, and perform iOS 11 update via iTunes as replacement.
3. Update to iOS 11 using iOS 10 IPSW file. Note that this method is recommended to advanced users only.

iphone stuck at recovery mode when updating to iOS 11

4. Stuck at recovery mode

This is a common error when we update to iOS 11 and jailbreak iOS 11 devices.

1. Shut down your device and restart it later. Then, check if this iOS 11 update error is fixed.
2. Restore your device from iTunes: update iTunes to the latest version and open it, connect your device to computer via USB cable, and then you will see an error message saying that it has detected a device in Recovery Mode. Then, click Ok on the pop-up error, navigate to iTunes, click on your device, select Summary, and tap on Restore device button. What is worth mentioning is that you may lose data and settings of your device if you haven't backed up your device.

iPhone battery drains faster after updating to iOS 11

5. iPhone Battery Drain

This is another common complaint after we upgrade to a new iOS. A standard iPhone is rated for 10 to 12 hours of battery life while chatting and surfing the web. However, some people may see abnormal battery drain after updating to iOS 11. Battery drains fast even without using.

1. Wait for a day or so. Update will expend a lot of power to download, search and do other things, so it needs some time to go back to normal. Wait for a day and see if it will return to normal level. If not, try other fixes.
2. Restart your device.
3. Check app battery usage and force quit a rogue app. To check battery usage, you should go to Settings-> Battery -> Show Detailed Usage -> Last 7 Days. And then you will see the battery usage of each app. Check if there's an app whose background time is much longer than on screen time. If there is, exit it from the background. If it keeps doing this, reinstall it or choose an alternative.
4. Turn on Low Power Mode.

Generally speaking, if you come across an error when using iTunes to update to iOS 11, you're likely to fix it by: updating iTunes to the latest version, updating your computer, plugging your device directly into computer's USB port instead of an attached keyboard or USB hub, restarting computer and iOS device, checking your computer's security software, and trying update again.

If you still can't troubleshoot your problems caused by iOS 11 update, you can ask help from Apple.
