iPhone not working after an update? This is why

Software updates are designed to correct bugs and improve your iPhone’s overall performance. However, after updating iOS, you may experience difficulties such as frequent crashes, unresponsive behavior, some apps not operating correctly, or sluggish performance on your iPhone. These flaws can degrade your entire experience rather than enhance your device’s functionality. You’ve come to the right place if you’re having troubles with your iPhone following an update.

This article will be divided into several sections because the term “iPhone not working” is general. For instance, the first section will cover the phone not turning on at all, the second section will discuss connection issues such as being unable to call someone, and the third section will discuss memory and so on.

iPhone not working after recent update – Fixed

To begin, let’s mention the possible causes of your phone not turning on and then go on to the solutions.

Possible causes of phone not turning on

  • Your device’s battery has died
  • Mobile operating system has crashed
  • The firmware has become corrupted.
  • Hardware issues

Let’s get to the good stuff now: the solutions.

Try recharging

If your iPhone won’t switch on following an update, it is most probable that the battery is entirely depleted. So, plug your iPhone into an original or MFI certified lightning cable and a reliable power source to charge it.

If your phone powers on but you’re encountering connectivity issues, such as being unable to make calls, move to the following step.

Network and connectivity issues

It’s possible that after updating iOS, you are unable to make a call from your phone. If this is the case, there are four simple and effective solutions available to you.

Restart your phone

If your phone is also not working properly after a software update, rebooting is the first solution that comes into mind. This is one of the simplest and most successful ways to fix a range of issues on any phone, including iPhones.

After restarting, check how your iPhone is acting; if the problem persists, proceed to the next step.

Toggle Airplane Mode

Toggle Airplane mode by heading to the Control Center and tapping the Airplane Mode symbol. Then, wait 5-10 seconds before tapping the icon a second time.

Make sure you’re in the area with strong network coverage

If the problem persists, it is possible that you are not in an area with no network service. First, check whether your friend’s and family’s phones have reception. You may also need to restart your iPhone or activate and reactive Airplane mode.

Reset iPhone network settings

After ensuring that network coverage available, the solution is to fix network issues by resetting the network settings on your device. In some cases, after updating iOS, issues related to connectivity rise, and they can be fixed by restarting the network settings. To do so:

  • Go to Settings, and then tap General.
  • After that, choose Reset and then tap Reset Network Settings.

After resetting the network settings, restart the phone to determine whether the issue has been resolved. If the problem is network-related, it is most probable that resetting the network will fix it.

Turn on and off Bluetooth or Wi-Fi a few times

Bluetooth and Wi-Fi connectivity issues were pretty common with iOS 14. Anyway,  Try disabling and reactivating your phone’s Bluetooth and Wi-Fi settings several times to see if this fixes your problem. If the solution was unsuccessful, restart the phone and check that the issue has been resolved. In most circumstances, restarting the device solves the problem.

However, in some instances, the issue may result from the update itself, and the manufacturer will provide a minor patch soon afterward.

Issues related to apps and memory

Apps and memory issues are common in phones after updating the firmware, and this is due to the re-indexing of the data. Follow the methods outlined below to resolve these issues.

Update or reinstall the apps

If you’ve recently updated and are experiencing problems with running apps, you should give your iPhone some time to adjust to the new version of iOS. This is due to the fact that when you update the software on your iPhone, your device will need to incorporate the new system as well as re-index the data.

After a few hours and a phone restart, if the problem persists, it is time to reinstall or update the malfunctioning app. It is worth noting that, as a result of out-of-date apps not being compatible with the most recent version of iOS, several issues may develop following the iOS upgrade.

Free up internal memory space

If your iPhone has become too slow following an update, you should check and manage your iPhone’s internal memory. Some iOS updates contain files in complex formats or large sizes, which might take a lot of storage on your iPhone. Delete unnecessary files and clear the cache to restore the smooth experience you enjoyed with your iPhone.

Factory reset your iPhone

This is your last resort if your iPhone keeps crashing or freezing even after you’ve tried the instructions in this article. However, don’t jump right into this method. Always back up your data before doing a factory reset so that you can restore it later.

Take your phone to a Apple Store

Suppose you’ve tried everything, and your iPhone still doesn’t work after an update. In that case, there’s a high possibility something is wrong with the internal components of your smartphone. for example, liquids or anything may have damaged your iPhone. In such cases, the best course of action is to take your iPhone to an Apple store and have it inspected.


The methods we’ve given in this article will most likely fix your iPhone not working after an update issue. However, if you are unlucky and continue to experience difficulties, you must consider the possibility that something is wrong with your iPhone’s hardware and is unrelated to the update.
