Apple added Control Center in iOS as part of a new quick menu in iOS 7. On your Apple iPhone or iPad, you can swipe up from any screen and enable/disable various services. One such service is Wi-Fi. While the Control Center makes managing Wi-Fi and other connectivity options on your iPhone quick and easy, most people don’t fully grasp how it works. That’s one reason why users can’t help but wonder how their iOS Wi-Fi turns on automatically.
You may have turned off Wi-Fi to use mobile data or save battery when you leave a known network. Realizing that turning off Wi-Fi doesn’t actually turn it off can interfere with how your battery drains and why the Wi-Fi network turns on automatically.
Let’s understand it in more detail.
How does the Control Center work?
The Control Center is designed as an easy-to-access menu where you can toggle a range of services like Wi-Fi, Bluetooth, and turn the flashlight on and off from anywhere on the screen. Disabling Wi-Fi from the Control Center will only disconnect your smartphone from the connected Wi-Fi network/router for about a day. It won’t turn off Wi-Fi service on its own, and after 24 hours, your iPhone or iPad will automatically connect to that Wi-Fi network.
Your iPhone will disconnect from your Wi-Fi router or hotspot and use temporary cellular data instead. Wi-Fi is still on. You can check that from Settings. Turn off Wi-Fi and open Settings > Wi-Fi to check.
You will notice the message ‘Disconnecting nearby Wi-Fi until tomorrow’ when you use the Control Center to turn it off. That’s why your iPhone reconnects to the saved Wi-Fi network even though you turned it off or should I say disconnected it.
In short, disabling Wi-Fi from the Control Center will disconnect the connection temporarily or only for 24 hours. If you want to turn it off completely, go to Settings > Wi-Fi to turn it off completely. On the other hand, if your cellular data connection is interrupted, the iPhone can fall back to the Wi-Fi network.
Why doesn’t Control Center turn off Wi-Fi completely
A lot of thought seems to have gone behind this reasoning. Wi-Fi is used for more than just connecting to the internet and surfing the web. Wi-Fi and Bluetooth are required to use options like AirDrop, AirPlay, Apple Watch, Mobile Hotspot, and other connected services. Turning off Wi-Fi will interrupt one of those services. That’s why disabling the option from Control Center to disconnect from Wi-Fi is temporary and not entirely sensible.
Turn off Wi-Fi properly
Use Settings if you want to turn off Wi-Fi forever. That will prevent iOS from automatically turning on Wi-Fi later. Go to Settings > Wi-Fi and disable this option. As discussed above, other features that depend on Wi-Fi will also stop working.
Note: Wi-Fi will automatically turn on and connect to the saved Wi-Fi network if you restart iPhone. That’s regardless of which method you use to turn off Wi-Fi.
Auto-join is disabled until
When you use Control Center to disconnect from Wi-Fi, it won’t automatically reconnect to the network until:
- It’s 5 am where you live (local time)
- You restart your iPhone
- You move to a new place
- You connect to a Wi-Fi network from Settings
- You turn on Wi-Fi from Control Center
Now you know why your iPhone automatically connects to the Wi-Fi network in the morning even if you turned it off at night. You should convert it, not disconnect it.
What happens to Wi-Fi in Airplane Mode
I don’t recommend using Airplane mode to turn off Wi-Fi. That will also turn off all other network connectivity options like Cellular, GPS, Bluetooth, and cellular data services.
Forget the Wi-Fi network
One way to keep Wi-Fi on and still make sure your iPhone doesn’t automatically reconnect to a Wi-Fi network is to use the ‘forget network’ option.
Step 1: Open Settings > Wi-Fi and select the name of the Wi-Fi network you are connecting to. For example, it could be your home or office router.
Step 2: Tap on Forget this network option and confirm when asked.
Note that you will need to re-enter the Wi-Fi password to join the network. Make sure you have it. Even better is when you disable Auto-Join and enable the Low Data Mode option in the same menu. That way you won’t have to forget the network and thus have to re-enter the password. Just turn off Wi-Fi from the Control Center and turn off Auto-Join. Your iPhone will not automatically reconnect to the selected Wi-Fi. When you connect manually by re-enabling Auto-Join, it consumes little data.
Using Wi-Fi Assist
Wi-Fi support will force the phone to use mobile data in case Wi-Fi is slow or not working at all. Instead, many users turn off Wi-Fi from the Control Center and then wonder how their Wi-Fi automatically reconnects.
Go to Cellular Data in Settings and scroll to the bottom of the screen to find the Wi-Fi Assist option. Enable it to enjoy uninterrupted internet even when Wi-Fi is not working properly. No need to launch Control Center and go through Wi-Fi settings over and over.
Connect the world
The Control Center acts as a window for the most commonly used and essential features. It is suitable for enabling and disabling services from any screen on the iPhone. The Wi-Fi option is one of them. Considering how ubiquitous Wi-Fi is these days, turning it off only momentarily disconnects Wi-Fi instead of disabling it. Now, you know why iOS keeps connecting to Wi-Fi networks.
