Many iPhone users find that their iPhone Wi-Fi will automatically turn on, usually after the system software is updated to iOS, restart the iPhone, or restart the iPhone. This frustrates many iPhone users because not everyone wants to enable Wi-Fi for a variety of reasons, especially when bringing their personal iPhone to areas with public, corporate, medical or government networks, such as workplaces, companies, or other public places (such as medical institutions or government agencies), they do not want to connect to those networks. A common solution is to keep Wi-Fi off (or forgetting the network), but many users find that iPhones turn on Wi-Fi on by themselves.

Let's explore together why iPhone Wi-Fi is turned on automatically and how to prevent this from happening. Yes, this is generally applicable to iPad users and iPadOS as well.

Why does iPhone Wi-Fi automatically turn on?

Many iPhone users have discovered that the iPhone will usually turn on Wi-Fi automatically when the system software iOS is updated, restarted, forced restarted, or turned off.

This may be intentional for Apple, as it has been widely documented and complained over the years, and while Apple's own support website has complained a lot, this behavior remains in the latest iOS update.

The iPhone automatically re-turns Wi-Fi may be to be able to install available updates, perform iCloud synchronization tasks (such as uploading iCloud photos), and other tasks and behaviors that use network connections. Cellular connections are also present, of course, but iPhones may be more inclined to use Wi-Fi networks that are usually faster, more stable and less susceptible to bandwidth limitations.

So, assuming this behavior is expected and expected, how can you prevent the iPhone from automatically enabling Wi-Fi on its own? Let's look at a little trick.

How to prevent iPhone from automatically enabling Wi-Fi after updating/booting/rebooting?

The easiest way to prevent iPhone from turning on Wi-Fi on its own after system updates, system boots up, or device restarts is to enable airplane mode first:

1. Before restarting or turning off the iPhone, slide down the Control Center and clicking the Airplane Mode icon to enable Airplane Mode – Airplane Mode disables all connections, including Wi-Fi and Bluetooth.

2. After the iPhone restarts, return to Control Center and turn off Airplane Mode—Wi-Fi will try to turn on again, but please quickly click to disable it and prevent Wi-Fi from turning on by itself.

This is a workaround to prevent Wi-Fi from enabling itself, and it does work, although you may have to try a few times before you can understand the switches in the flight mode and the network connections associated with it.

Why didn't Apple fix this so that if Wi-Fi on iPhone is off, it stays off?

There are a lot of public complaints and posts about this issue on the Apple discussion board, and Apple certainly knows about this frustrating situation, but since there are no changes or fixes, it can be speculated that this is the expected behavior.

Similarly, iPhones perform many tasks that require network connections, and generally, Wi-Fi connections are more stable, faster, more reliable than cellular networks, and have fewer bandwidth limitations. Therefore, it can be assumed that the iPhone will automatically turn on Wi-Fi during boot and restart so that it can perform necessary network-related tasks without relying as fully on cellular connections as possible.
