Common iOS 15 problems and solutions

Below, we’ll explain the top iOS 15 problems along with any fixes that have been figured out so far. Some of the issues are solved by simply updating to the latest version of iOS; when we note that an update addressed the issue, consider it fixed for every later version of iOS unless we say otherwise.

Some iPhones Won’t Charge in iOS 15

If you’ve got an iPhone 11 or iPhone 12 , you might encounter some charging problems with iOS 15.

Simply put, it sounds like there are times when these models of phones simply won’t charge. The reason for this is unknown, but it seems to be a simple software issue that will probably be fixed in the near future.

However, there’s a way to fix it before then. As long as you make sure that you see the charging symbol and hear a beep when you put your lightning cable in, then you’re fine. Otherwise, don’t trust that your phone is charging.

What to do?

Dealing with a phone that has stopped charging can be extremely frustrating. But do not worry. You may easily fix it. If your phone refuses to charge the battery, here is what you can do:

  1. Is your iPhone plugged in? Yes, this is pretty obvious but check anyway. Make sure that your iPhone is plugged in properly and it is connected to a power source. Furthermore, make sure that you hook up everything as it should be. Check each contact. There should be only a very minimal wiggle room.
  2. Inspect your cables and adapter. Make sure that you are using the charging accessories that came with the iPhone.
    Alternatively, make sure that your accessories are Apple certified. You may see a “This Accessory Is Not Supported By This Device” message.
    In addition, make sure that:
    your cable or adapter are not damaged. If it’s faulty, do not use the damaged accessories. Use another cable or adapter.
  3. Check the power source. It is possible that your iPhone or your cable and adapter may not be faulty, the problem may be the power outlet. You may want to plug your iPhone to a different power source:
    If you’re trying to charge from the wall, try even a different socket. Make sure that the wall outlet is not faulty.
    If you’re charging from a USB port, plug your iPhone to a different port and if the problem persist, plug your device directly into a wall socket.
  4. Is your charging port dirty? One of the causes of your iPhone’s charging problem in iOS 15 is dust, lint, and debris. It is possible that this dust and dirt can prevent the connector from establishing an electrical connection. This means that it is possible the lightning port may be clogged. This can cause your charger port to stop working. Try cleaning out the port with a toothpick, and then try charging your iPhone again.
  5. Is wireless charging not working? If wireless charging is not working, please do the following:
    If your iPhone has a thick case, take it off.
    Place your iPhone in the middle of the charger.
    Ensure that your wireless charger is properly plugged to a power source.
  6. Check for updates. make sure that your iPhone is running the latest version of iOS 15. Updating your iPhone is easy.
    Head to Settings > General > Software Update. If there is an update available, follow the onscreen prompts to install the updates on your iPhone.


Plenty of users have complained on social media and forums about losing Wi-Fi after upgrading to iOS 15. Wifi connection problems always crop up alongside a new iOS release, and iOS 15 has been no different—it must be something about the application of a brand new software layer that confuses your iPhone (or the networks that it’s connecting to), often resulting in dropped or unstable connections.

In the case of iOS 15, one of the most widely reported problems has been issues with dropped wifi connections. According to numerous users, iPhones running iOS 15 tend to lose their connections to wireless internet and then refuse to reestablish the link, which causes problems for just about everything you could want to do on a smartphone.

What to do?

  1. Simply restart your iPhone: (Settings > General > Shut down>
  2. Enable Airplane mode, wait a a minute, and then turn it off (Settings > Airplane Mode).
  3. Ensure that you are not too far from your Wi-Fi router/modem and your iPhone is within range and can get strong signals.
  4. Make sure that your iPhone is running the latest version of iOS 15. Head to Settings > General > Software Update.
  5. You may try forgetting your Wi-Fi network. And then reconnect. Here is how: Head to Settings > Wi-Fi > tap the i > Forget This Network to rejoin your network.
  6. If you are using a VPN, disconnect it and then try again (Settings > VPN).
  7. Reset network settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Please note that resetting network settings will delete all of your network settings, for example, your saved Wi-Fi passwords will be deleted.
  8. Restart router: Restart your router. Simply unplug it from the power outlet, leave it unplugged for a a few seconds and then plug it back in.
  9. Update your router and modem with the latest firmware: You may want to check the manufacturers documentation.
  10. See if there’s an internet outage: Maybe the internet is down in your area. Contact your Internet service provider or cable company. It is possible that they may be experiencing an outage. See if there is an issue with your account. Maybe you forgot to pay your bill and they disconnected your Internet. Simply contact them.

iPhone showing ‘no service’

Are you losing cellular service on your iPhone in areas you’ve previously had signal?

This issue doesn’t impact all users, but it has been reported on Apple’s forums multiple times with very similar circumstances, where it limits your phone’s signal more than before you upgraded the software.

What to do?

  1. Undertake a carrier settings update: Move to an area where you know you have previously had coverage with your cellular provider. If you get signal at home, you should be able to do this from there. You should then go to the Settings app, tap on General and then tap on About. If there is an update available, you will then be able to apply it there under carrier settings. If that hasn’t resolved your issue, try the troubleshooting tips below.
  2. Check your settings: Let’s check basic settings. The following settings will disable cellular and Wi-Fi service if they are enabled.
    Make sure that Airplane Mode is not enabled. (Settings > Airplane Mode)
    Make sure that Cellular Data is not disabled. (Settings > Cellular > Cellular Data)
    Are you traveling internationally? You may see this message if Data Roaming is disabled. Go to Settings > Cellular > Cellular Data Options > Data Roaming and enable this.
  3. Check-in with your carrier: Contact your carrier (Verizon, AT&T, T Mobile etc). Perhaps they are experiencing a temporary outage that may be affecting your iPhone services. When you call them, if this is the issue, they may provide an estimated time of repair completion. Furthermore, even if your carrier is not experiencing outages, it is possible that your wireless service is suspended or even canceled. Contact your current cellular network provider.
  4. Update your iPhone: Your problem that causes the no service problem could be a common problem affecting a lot of users, due to iOS software bugs. If this is the case, Apple fixes these bugs quickly. So simply update your iPhone to the latest version of iOS. Go to Settings > General > Software Update. And if there is an update available, update your phone.
  5. Check your SIM card: Is your SIM card placed properly? It may be out of place. Perhaps it is damaged? You may want to remove your SIM card and place it back. Here is how:
    Turn off your iPhone
    Find the SIM tray
    There is a hole beside the tray
    Using a paper clip, push in and open the TrayRemove SIM and Insert
    Remove the SIM card
    Check your SIM card, does it look damaged. If it is damaged, contact your current carrier fort further support. Does it look dirty. If it is dirty, you may want to clean with a clean lint-free cloth.
    If it is not damaged, place the SÄ°M in the tray and insert the tray back in.
    Turn on your phone
  6. Reset network settings: To do this, you should head to the Settings app, tap on General, tap on Transfer or Reset iPhone, select reset and then tap on Reset Network Settings. Be aware that this will mean your phone forgets your Wi-Fi passwords, but it may be worth that small annoyance to try to fix the issue.

If this hasn’t worked, take a look at the guide on how to troubleshoot iOS 15 cellular data issues.

Otherwise, you may have to wait until Apple rolls out a new update.
