[Update] iOS 15 for the iPhone - New update technology and possible problems

The public version of iOS 15 was out yesterday. It can now be installed on all compatible Apple iPhone models. But should you install the new operating system? Or is it advisable to wait for the first update to avoid possible errors? In search of answers to these questions, I have studied a few articles on other sites. You can find my summary here. You can also find some more information about the iOS 15 update on the Apple iPhone.

Preview: Create an encrypted backup on the Mac / PC

As with any major update or system upgrade, it is advisable to create a backup beforehand. Regardless of whether you want to update your Mac to macOS 12 Monterey or update your iPhone to iOS 15, a backup saves your data and enables you to easily reset it in the event that something goes wrong. 

By the way, the iPhone backup should be encrypted so that your passwords are also backed up. If you choose a non-encrypted backup, the login data for websites and apps will not be saved for security reasons. You can do the iPhone backup on the Apple Mac via the Finder or on the Windows PC via iTunes.

iPhone settings: Here you can find the update to iOS 15

Once you have created the backup, you can devote yourself to the update to iOS 15, which you can find in the iPhone settings. It hides a little inconspicuously, even on highly compatible devices like the iPhone 12. This is the best way to proceed:

  1. Opens the Settings-App on your Apple iPhone
  2. Tap on the point in the list General
  3. Now choose the point software update
  4. Type below under Also available "Update to iOS 15"
  5. Chooses Download and install and follow the instructions on the display
You can find the update to iOS 15 on the iPhone via Settings> General> Software update> Update to iOS 15. The screenshots were taken on the iPhone 12 Pro with iOS 14.8.

New update technology for iPhones with little storage capacity

With iOS 15 and watchOS 8, Apple provides the solution to a problem that has long been addressed by users: system updates when there is little free memory. If the current system, the installed apps and stored data did not release enough gigabytes, there was a problem so far. IPhone SE (1st Gen) users with only 16 GB can tell a thing or two about it.

With the current versions this should now be a thing of the past. The new operating system should now be able to be installed even with less than 500 MB free memory. This becomes possible because the apps are backed up and then deleted. With the space gained, the new OS is installed and then the apps are reloaded. 

Update: Messages about iOS 15 errors, bugs and problems

Below you will find more general problems and bugs that can affect the iPhone with iOS 15. Here I have collected a few more specific bugs, bug reports and objections that I have noticed in the last few days through articles from various sources. Next to the respective mention you will find the corresponding source (in brackets):

  • Message "iPhone Storage Almost Full" or "iPhone Storage Almost Full", although there is sufficient storage space on the iPhone (Source)
  • Display of more free memory than is actually available or more memory space than the device actually has (Source)
  • Control of the AirPods Pro via Siri does not work (Source)
  • Muting the iPhone also prevents app audio (Source)
  • Problems with the mail app (see comments on this post)

I haven't really noticed a problem with iOS 15 myself. Only one strange bug occurred after upgrading the iPhone operating system: If I start an audiobook in the Audible app and switch off the display, the playback is paused. Only after I quit and restart the app can I continue playback even when the display is switched off. I read on the net that the bug has been around for a long time; I don't understand why it only appears on iOS 15.

Problems with iOS 15 on iPhone

As mentioned at the beginning, I searched the net for a few articles with known iOS 15 problems. I noticed a few things that you can see in the following list. Some are more general complaints that come with pretty much every operating system upgrade, while others are more specific:

  • Problems with download and / or installation (if the system gets stuck, use a hard Reset)
  • Browser-based conference services, e.g. B. BigBlueButton (BBB), could be extremely quiet even at 100% volume
  • The cellular reception could be disturbed or unusually weak (try switching airplane mode on and off, restarting the iPhone or resetting network settings)
  • Problems in the display or delays in the user interface (a simple restart may help here)
  • You may experience problems with AirPlay
  • You may experience problems with Touch ID or Face ID
  • An abnormally high battery load could appear
  • Possible problems with Bluetooth, WiFi, third-party apps, iMessage, CarPlay, etc.

The problems listed do not have to occur, but they could. Some can be resolved by simply rebooting or resetting certain settings. If you have made a backup, in the worst case scenario, you can simply reset your iPhone to iOS 14.

    It is a shame that not all new functions are available worldwide. For example, the "visual lookup" feature in the photo app is only available in the USA.
    Only the reason for this restriction is not clear to you.

    Otherwise, the update is relatively successful in my opinion. I couldn't understand or find any of the errors described in the article. Only my wife's iWatch hung up after the update, which was fixed after a restart.

    I have an iPad mini 5. Since the iOS 15 update, the email program no longer works, so emails can no longer be sent and retrieved. I usually use Spark and Outlook. The battery is empty very quickly and does not even take 5 hours with normal use. Safari takes longer to load. Sometimes pages hang up - rather unusual for Apple. Some pages don't even load ... Hope for an update, it should have left it at "14" for now. But would not be of any use now.

      In the first few days after the update, this can happen with the battery every now and then. I would also do a reboot to see if it helps with the other issues. If not, then maybe an encrypted backup, reset iPad and then restore the backup. That also solves one or the other problem.

    The iPhone Se (1st generation) does not have a notification tone for mail although it is activated!
    Otherwise well done!

    "If you've made a backup, in the worst case scenario, you can simply reset your iPhone to iOS 14."

    Is that really true ? I can remember that some time ago resetting the iOS from an iTunes backup was not possible, but special ... _Restore.ipsw files had to be installed.

    Or am I confusing something?

      Hello Carlo! Unfortunately, I don't have an iPhone with iOS 14 to test it with, but I think if you've done a full backup it should be possible.
