The iPhone is one of the most advanced smartphones on the market, but that doesn’t mean it’s bug-free. Over time, it’s normal for users to experience some glitches, ranging from slowness to issues with Face ID or the battery. Additionally, there may also be issues with the apps we download.
Fortunately, many of these problems can be solved, and you don’t need to be an expert to resolve them. Below, we’ll show you the most common iPhone errors and how to fix them yourself, something you can try it yourself before going to the service center.
The most common iPhone errors
Has this happened to you? Users have always suffered from certain problems with the iPhone. Some of them are among the most common across all generations of the family. Here’s a list of 10 of them.
1. The iPhone is running slower than usual
Over time, your system may become bloated. This could be due to a pending update, full storage, resource-intensive applications, or simply too many processes.
2. Apps close by themselves
If you notice certain apps closing unexpectedly, they probably need an update or reinstallation. If the issue occurs with multiple apps, it could be related to your iOS version.
3. The battery lasts much less
Battery degradation is inevitable over time. Constantly charging it to 100%, overheating, and intensive use can accelerate its deterioration.
4. You’re running out of storage
Many users face this problem, especially those with limited-storage models. Photos, videos, and apps take up a lot of space.
5. The iPhone gets too hot
If your iPhone gets hot for no apparent reason, it could be due to an iOS bug or a poorly optimized app. It can also happen when using it while charging or when exposed to sunlight.
6. Face ID or Touch ID not working properly
If unlocking fails, it’s likely that the sensor is dirty or damaged. It could also be due to a bump or scratch on the front camera or home button.
7. The microphone is not heard well
If your voice sounds muffled or cannot be heard during calls, check that the microphone grille is clean and free of dirt or moisture.
8. Black Screen (Black Screen of Death)
Your iPhone appears to be on, vibrates, and rings, but the screen remains black. This is a more common problem than it seems, and it can be fixed.

How to solve the most common errors
The most common errors sometimes have equally common solutions. Before going to Apple for assistance, you can try some very effective solutions:
1. Keep your iPhone updated
Going to Settings > General > Software Update will allow you to install the latest version of iOS and fix any issues.
2. Restart your iPhone
Turning your device off and on may free up memory and resolve temporary errors.
3. Update or reinstall problematic apps
If a specific app crashes, check if it has a newer version or delete and reinstall it.
4. Free up storage space
In Settings > General > iPhone Storage, you can see which apps are taking up the most space and delete them if you’re not using them.
5. Clean your iPhone
Use a microfiber cloth and isopropyl alcohol to clean the sensors, microphone, and camera.
6. Manage background updates
Go to Settings > General > Background App Refresh and disable unnecessary apps to improve battery life and performance.
7. Force restart
Quickly press volume up, then volume down, and hold the side button until you see the Apple logo.
8. Restore iPhone from scratch
If all else fails, back up your data and go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
9. Contact Apple Support
If the problem persists, it’s best to contact Apple Support or visit an Apple Store for further evaluation.
If you notice that the problem you’re experiencing has become more frequent or the previous solutions aren’t adequate, you should seek professional assistance from Apple for a professional solution or, if applicable, to process your warranty if applicable.
