The iOS 11 update is listed as 1.7GB in size, but you need to prepare more space for that. According to experts, you will need at least 4GB of storage space before comfortably upgrading. 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.

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.

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

Here we will list top 7 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"

Solutions:
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.

4. Stuck at recovery mode

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

Solutions:
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.

Solutions:
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.

cannot send email after updating to iOS 11

6. Cannot Send Mail. The message was rejected by the server.

After updating to iOS 11, Outlook.com, Office 365, and Exchange 2016 account holders reported that they cannot send or reply to emails using Apple's native Mail app in iOS 11. Instead, they receive an error message "Cannot Send Mail. The message was rejected by the server."

Solutions:
Currently, Apple and Microsoft are still working together to resolve the problem occurring after updating to iOS 11. A fix isn't delivered, but Microsoft offers the following workaround:
[1] Download the free Outlook for iOS client from the App Store;
[2] Ask the system administrator to disable HTTP/2 in Windows Server 2016, if you use the iOS 11 Mail app to sync data from Exchange Server 2016 that is running on Windows Server 2016.

iOS 11 freezing iPhone iPad

7. iOS 11 freezing phone

Many people reported that their iPhones, from iPhone 5s to iPhone 7 Plus, freeze randomly during normal use after updating to iOS 11, on Apple community and other sites.

Solutions:
1. Force your non-responsive iPhone or iPad to reboot.
2. Reset All Settings to fix iOS 11 freezing iPhone/iPad problem: go to Settings -> Reset -> Reset All Settings. Type in password if required. After doing this, you will only lose your preference for AirDrop, Bluetooth, Wi-Fi, privacy and other settings rather than the apps, media files on your iOS 11 iPhone/iPad.
3. Downgrade iOS 11 back to iOS 10.

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.
