Most Common iOS 15 Problems and How to Fix Them

With iOS 15 having just landed on our devices, it’s to be expected that there will be some bugs and performance issues while users start to test it and push it to its limits, we see this with every update. Although the new update was of course Beta tested, it’s often impossible to catch every problem, and Apple will be looking to fix issues as they arise.

But that doesn’t help us right now, does it! So what are the current issues with iOS 15 that we’re aware of so far? Some users are experiencing issues with installation and Touch ID, whereas others are reporting problems with UI lag, battery drain, and Wi-fi connections. Although some of these are the same as the ones we’ve seen in iOS 14, some of these are also brand new issues.

Although some of these issues will see you having to wait for an update, or perhaps even taken to an expert at your local Apple store, many of these can actually be fixed by yourself without having to stress. Let’s take a look at the first of these now.

Fix: #1 Installation Problems

Installation Problems

The first of these potential issues you may be experiencing is problems with the actual installation process itself. Fortunately, this can be easily rectified by performing a hard reset on your iPhone. Once your iPhone is restarted, simply try again and repeat the process if necessary.

Sometimes you’ll find that the download is taking much longer than it’s meant to. To fix this, pause the download. After giving it several minutes, try again. If it’s still not working after that, check you’re not having issues with your Wifi router.

Fix: #2 Excessive Battery Drain

Excessive Battery Drain

The second issue we’re going to look at is excessive battery drain. First off, you’re going to want to turn off any apps that may be running in the background and draining the battery. By this, we mean automatic updates. Don’t download large files when not connected to a charger, or play games for extended periods of time. If all of the standard battery fixes aren’t working for you, there is of course a chance you may have a faulty battery. If you’re unsure or need further assistance with a particularly bad battery, you should contact Apple and get yourself a replacement. You can either pop into a store and speak to an Apple Genius or contact customer support over the phone or email.

Fix: #3 Bluetooth Issues

Bluetooth Issues

Another issue you may experience issues with your Bluetooth after installing iOS 15. This is not all that uncommon, as we have seen similar issues with previous updates. Here are some of the fixes that have worked for us when previously encountered.

First off, you need to go to your Settings, then Bluetooth. Then select the connection by pressing the ‘i’ in the circle. Now all you have to do is press ‘Forget this Device’, then try to reconnect. Chances are this will fix the issue. If not . . .

Go back to your Settings. Select General, then Reset, then Reset Network Settings. Doing this will not start the process of resetting your network settings. You should bear in mind that your iPhone will also forget any passwords to any Wifi’s you have been using, so you’ll need to reconnect to everything.

You can also try resetting your iPhone to factory settings. To do this, tap Settings, General, Reset, Reset All Settings. As with the previous issues, you should seek a customer support agent if none of these steps are fixing the problem for you.

Fix: #4 WiFi issues

WiFi issues

It is possible that after installing iOS 15 you may experience issues with your WiFi speeds or connections. There are several things that you can do to fix this, so let’s take a look at them now.

First off, you should do the usual trick of unplugging your router and plugging it back in. If this doesn’t work for you, or if you can’t get access to the WiFi you’re currently connected to, you should go to your iPhone’s Settings. From there you can force your iPhone to forget the WiFi network then try to reconnect as we did in the previous issue. To do this with the WiFi, from Settings, select the WiFi connection you wish to forget by pressing the ‘i’ next to it. Then, press ‘Forget This Network’.

Hopefully, this worked. If not, follow the steps in the Bluetooth issues steps above to reset your iPhone’s Network Settings. And again, if the problem persists, seek the advice of an Apple expert.

Fix: #5 No Service Issue

WiFi issues

Next up is the ‘No Service’ issue that several people seem to be getting after installing iOS 15.

The first thing you’ll want to make sure of before you commit to any resets or settings changes is if there’s a general cellular outage in your area. You can actually do this online within minutes if you go to Down Detector, and rule that out as the cause of the problem.

If it’s definitely a problem with your iPhone, the first thing you should do is restart your phone and see if that fixes the issue. If it persists, try turning airplane mode on, then off again.

The final fix for this issue is to turn your Cellular Data off then on again. To do this, go to Settings, then Cellular, then toggle the Cellular to off. After a minute, turn it back on.

Fix: #6 FaceTime Issues

FaceTime Issues

Yet another issue we’ve been hearing about is problems with sending or receiving FaceTime calls. An easy way to tell if this is a problem with your device rather than an issue with Apple is if there’s a green symbol next to FaceTime. Double-check your phone is connected to a stable WiFi source, or that you have a good signal.

A quick fix is to go into your Settings, then FaceTime. Now, if you see ‘Waiting for Activation’, you should turn FaceTime off then on again. If this doesn’t work, reset your phone.

You should also head into your settings and make sure that your FaceTime is toggled on for use with your Cellular Data.

Fix: #7 & #8 App Issues and Visual Voicemail Issues

Airplane mode

Several users are reporting issues with Apps as well as visual voicemail issues after installing iOS 15.

The first thing you should do is to restart your phone. If this doesn’t fix either of the issues, you should check if any of the apps have updates available in the App Store. This is recommended because developers will have to adjust their apps to make sure they work with iOS 15, meaning there’s a chance it’s not your iPhone at fault. You can either try deleting the app and reinstalling, or contact the developers directly. To fix the visual voicemail issue, you should listen to the voicemail all the way through, then close the phone app before reopening it. This should fix the problem. If it doesn’t, restart your iPhone.

Fix: #9 & #10 Random Reboots & GPS Issues

GPS issues

And last but by no means least, are the issues of random rebooting and problems with the GPS after installing iOS 15. Thankfully, a quick restart of your device may fix this. Sometimes you may encounter problems with your iPhone if it’s been a significant period of time since the last time it was turned off.

You should then update any and all applications that require it, and contact an Apple Genius if the problem persists. As with previous steps, you can also try toggling your Airplane mode off then on again after thirty seconds.

One last thing to check with your GPS is that it still has ‘permission’ to use your location, which is located in Location Permissions. To check this, go to Settings, Privacy, Locations Services. Select the app that is causing you grief and check that you don’t have the ‘never’ option selected. If it is selected, the GPS will not work no matter what you try.

Still not working? Try turning Location Services off, then back on after thirty seconds. To do this, go to Settings, Privacy, Location Services, then toggle it off. After thirty seconds, toggle it back on again.

One final fix you can try to get your GPS up and running again is to reset your Network Settings. To do this: Go to Settings, General, Reset, Reset Network Settings. Note that you will have to enter any passwords for WiFi that may have previously been connected.

A Summary

 Now you’ve seen all of the most common issues and problems with iOS 15 and how to fix them, but you should keep in mind that the issue may at times be with Apple themselves. Whenever a new update comes out, there are going to be an issue, but you can rest assured that Apple is working on fixes for them from the moment they come to their attention. If you’re not convinced it’s not an issue with your iPhone, there’s no harm in taking it into your locale Apple store to get it checked out by an Apple Genius.
