The problem of being unable to update iOS15 occurs. The common reasons are as follows: 5. You can check whether your iPhone has the following conditions:

iOS is not compatible with the iPhone, which means that the iOS system Doesn't work on iPhone.

Due to rapid battery drain or unstable network, we encountered interruptions when updating the game. This situation may cause us some trouble, but we can take some measures to solve the problem. First of all, when our power is almost exhausted, we can consider connecting a charger or using a mobile power supply to charge the phone. This ensures that the phone has enough power to continue updating the game. Secondly, if we encounter network instability when updating the game, we can try to reconnect to Wi-Fi or switch to data traffic. Sometimes, unstable network signal may be caused by our location or poor network conditions. By reconnecting or switching networks, it is possible to resolve this issue and continue updating the game. In short, the battery is running out or the network is unstable, which may cause game updates to be interrupted, but by connecting a charger, using a power bank, or reconnecting to the network, it is possible to solve this problem and continue to enjoy the game.

When we use iPhone, we sometimes encounter a problem, that is, the size of the new iOS system exceeds the remaining storage space of our iPhone. This means that we cannot install the latest iOS system directly through software updates on the phone. In order to solve this problem, we can try the following methods: 1. Clean up storage space: First, we can delete some unnecessary files and applications to free up some storage space. You can check which apps are taking up a lot of space and decide whether to delete them by opening Settings - General - Storage and iCloud Usage. 2. Use iTunes to update: If our iPhone does not have enough storage space to directly update the iOS system, we can try to use iTunes to update. First, we need to connect the iPhone to our computer and open iTunes. Then, on the device page, select the Summary tab and click the Check for Updates button. If a new iOS system version is available, iTunes will prompt us to update. Before updating, iTunes will provide an option to back up our iPhone data in case something unexpected happens during the update process. 3. Reset iPhone and restore backup: If the above two methods don't work, we can try to restore iPhone to factory settings and restore our data from backup. This will delete all data on the phone and reset it to factory condition. After completing the recovery, we can choose to recover data from the previous backup, including applications, photos, contacts, etc. In general, when the remaining storage space of our iPhone is not enough to install the latest iOS system, we can solve this problem by clearing the storage space, using iTunes to update, or resetting the iPhone and restoring the backup. I hope the above methods can help everyone!

Open [Settings]-[General]-[iPhone Storage Space] to check the storage space usage of your iPhone, and then update again when there is sufficient memory.

Since the iOS update takes a long time, make sure the network is stable to avoid interrupting the update process and causing the iPhone update to fail.

Open the [Settings] menu of the device, and then find the [Unlimited LAN] option. In this option, we need to choose a WiFi with a good network signal to connect.

Method 4: Force restart iPhone

When we encounter some basic iOS system failures, such as stuck black screen, recovery mode, etc., we can try to use force restart to fix it. Force restarting is a simple yet effective method. In this case, we don’t need to worry about data loss because force restart just restarts the device and does not make any changes to the data. So, if you encounter these problems, you might as well try a force restart first, which may solve your problems.

Different models of iPhone have different force restart methods. You can try force restarting your iPhone in the following situations: 1. iPhone 6s and earlier models: Press and hold the Home button and Sleep/Wake button at the same time until the Apple logo appears. 2. iPhone 7 and iPhone 7 Plus: Press and hold the Volume Down key and Sleep/Wake key at the same time until the Apple logo appears. 3. iPhone 8, iPhone 8 Plus, and iPhone X: Follow these steps: - Press the volume up key quickly. - Press the volume down key quickly. - Press and hold the side button until the Apple logo appears. 4. iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max: Follow these steps: - Press the volume up key quickly. - Press the volume down key quickly. - Press and hold the side button until the Apple logo appears. Please note that before performing a force restart, make sure your iPhone is connected to a power source and has sufficient power. If your iPhone still does not work properly after force restarting, it is recommended that you contact Apple customer service or go to an Apple authorized repair service center for help.

Full-screen models (iphone8 and later): Quickly press the volume up and down keys respectively, and then continue to press the power key until the Apple logo reappears after the device goes black, then release all keys;

iPhone 7, iPhone 7 Plus, etc.: Press and hold the top (or side) button and the volume down button at the same time until the Apple logo reappears after the device goes black, then release all buttons;

In models before iPhone 7, if you encounter some problems, such as device failure or need to restart, you can follow the steps below: 1. Press and hold the Home button and the power button on the device at the same time; 2. Wait for the device’s screen to turn black, and then the Apple logo reappears; 3. After seeing the Apple logo, you can release all the buttons. This way, your device will restart and the issue may be resolved. This method worked very well on previous iPhone models and I hope it will be helpful to you.
