Disabling Wi-Fi on your smartphone is a simple but important step that helps conserve battery life, avoid unnecessary data usage, and protect data on public networks. Many users are accustomed to using mobile internet when the Wi-Fi signal is weak or absent, but not everyone knows that even when connected but inactive, Wi-Fi continues to consume power. In this article, we'll cover all the possible ways to disable Wi-Fi on devices running Android And iOS, including hidden functions and process automation.
Regardless of the phone model, be it Samsung Galaxy S23, iPhone 15 Pro or budget Xiaomi Redmi — the algorithm of actions remains almost identical. However, there are nuances related to the operating system version and manufacturer. For example, on some devices Huawei or OnePlus The settings menu may differ, but the general principle remains the same. If you frequently switch between networks or want to optimize battery life, this guide will be a helpful guide.
The article will also discuss why Wi-Fi sometimes fails to turn off using standard methods and how to solve this problem. For example, On some Android firmware versions (especially custom ones), the Wi-Fi module may automatically turn on when connecting to a known network, even if you turned it off manually.This behavior can be adjusted through additional settings or third-party applications.
═══
Method 1: Disable Wi-Fi via the notification panel
The fastest and most intuitive method is to use the notification panel (also known as the "curtain"). This method works on all modern smartphones, regardless of brand and OS version.
On Android:
- Swipe down from the top of the screen to open the notification panel.
- If the Quick Settings widgets don't appear, swipe down again (twice on some devices).
- Find the icon Wi-Fi (usually stylized as a network signal or antenna) and tap it. If the icon is highlighted, it means the module is active.
On iOS (iPhone):
- Swipe down from the top right corner of the screen (on models with Face ID) or from bottom to top (on models with a button Home).
- Find the Wi-Fi icon in the control panel and press it. The blue light will disappear, confirming the disconnection.
Please note: On some devices Android (For example, Xiaomi or Oppo) A long press on the Wi-Fi icon in the notification shade opens the network settings menu. To simply turn off the module, just tap it briefly.
Method 2: Disable Wi-Fi in your phone settings
If the notification panel is unavailable for some reason (for example, due to a system crash or work profile restrictions), you can disable Wi-Fi through the settings menu. This method is universal and works even on older versions. Android (starting from Android 4.0) And iOS (starting from iOS 7).
For Android:
- Open the app
Settings(gear icon). - Go to the section
Network and Internet(on some devices -ConnectionsorWi-Fi). - Tap on the item
Wi-Fi. - Move the slider to the position
Off(or uncheck if the interface is outdated).
For iOS:
- Launch
Settings. - Select a section
Wi-Fi. - Move the slider to the gray position (on the left).
On some firmware versions Android (For example, MIUI from Xiaomi) There may be an additional option in the Wi-Fi menu Advanced settings, where you can disable automatic connections to known networks. This is useful if your phone accidentally turns on Wi-Fi in the background.
☑️ Check for Wi-Fi disconnection
Method 3: Disable Wi-Fi using your voice assistant
Modern smartphones support voice control, which is convenient when your hands are full or the screen is locked. Voice assistants Google Assistant (For Android) And Siri (For iOS) allow you to turn off Wi-Fi with one command.
For Android (Google Assistant):
- Activate the assistant by saying
Okay, Google.or by holding the buttonHome(on older devices). - Tell:
Turn off Wi-FiorTurn off your wireless network. - Confirm the action if required.
For iOS (Siri):
- Hold down the side button (on iPhone X and newer) or button
Home(on older models) to invoke Siri. - Tell:
Turn off Wi-Fi. - Siri will execute the command and notify you that the shutdown was successful.
Voice control is convenient, but it has limitations. For example, on some devices Android You may need to unlock the screen to execute the command. It's also worth remembering that voice assistants only work with an active internet connection (via a mobile network or a previously connected Wi-Fi network), making this method useless in airplane mode.
Method 4: Automatically turn off Wi-Fi on a schedule
If you want Wi-Fi to turn off at a specific time (for example, at night to save battery or during work hours to improve concentration), you can set up an automation. Standard tools or third-party apps are suitable for this.
On Android:
- 📱 Through "Sleep Mode": Some firmware (for example, EMUI on Huawei) allow you to turn off Wi-Fi at night. Go to
Settings → Battery → Sleep Modeand set up a schedule. - 🤖 Using the app MacroDroidCreate a macro with the "Time of Day" condition and the "Turn off Wi-Fi" action. The app is free, but has paid features.
- ⚙️ Through Tasker: This powerful automation tool allows you to create complex scenarios, such as turning off Wi-Fi when connected to a charger or when the battery level is low.
On iOS:
- 🕒 Short-term access: IN
Settings → Wi-FiTap on the connected network and enable the optionShort-term accessThis won't turn off Wi-Fi completely, but it will limit its use. - 🔄 Automation in Shortcuts: Create a shortcut with the action "Set Wi-Fi" and set it to run at a time or event (for example, when leaving the house).
Automatic shutdown is convenient, but requires preliminary configuration. Android This often requires superuser rights (root), if you use advanced tools like TaskerOn . iOS opportunities are limited by politics Apple, so full automation is only available through workarounds.
Why might Wi-Fi turn on by itself?
On some Android devices, the "Wi-Fi Assist" or "Adaptive Wi-Fi" feature automatically connects to known networks to save mobile data. Disable these options in your Wi-Fi settings.
Method 5: Disable Wi-Fi in Airplane Mode
Airplane mode (Airplane mode) disables all wireless modules, including Wi-Fi, mobile network, Bluetooth And GPSThis is a radical method, but it is guaranteed to disable Wi-Fi, even if standard methods fail.
How to enable airplane mode:
- 📲 On Android: swipe down on the curtain and tap on the airplane icon or go to
Settings → Network & Internet → Airplane Mode. - ✈️ On iOS: open the control panel and click on the airplane icon or go to
Settings → Airplane Mode.
Once airplane mode is activated, all wireless connections will be disabled. To restore Wi-Fi only (for example, to use the internet without a mobile network), you can manually enable it in the settings without exiting airplane mode. Android this is done through Settings → Network & Internet → Wi-Fi, on iOS - through Settings → Wi-Fi.
⚠️ Attention: In airplane mode it also turns off Bluetooth And GPS, which may interfere with the use of wireless headphones or navigation apps. If you need to use only Wi-Fi, enable it manually after activating Airplane Mode.
What to do if Wi-Fi won't turn off?
Sometimes users encounter a situation where Wi-Fi won't deactivate using standard methods. This may be due to software glitches, viruses, or firmware issues. Here are a few ways to resolve this:

FAQ: Frequently asked questions about disabling Wi-Fi on your phone
Is it possible to turn off Wi-Fi on a child's phone remotely?
Yes, if you have a parental control app installed on your device (e.g. Google Family Link, Kaspersky Safe Kids or Qustodio). These programs allow you to restrict Wi-Fi access according to a schedule or manually via a web interface. Also, some routers (for example, ASUS or TP-Link) support the "Parental Control" function, where you can block network access for a specific device by MAC address.
Why does Wi-Fi turn on by itself even though I turned it off?
This happens because of functions like Adaptive Wi-Fi (Android) or Wi-Fi Assist (iOS) that automatically connect to known networks to save mobile data. Disable these options in your Wi-Fi settings. A battery optimizer or a third-party app (e.g., Facebook or WhatsApp, which check the connection in the background). Check the app permissions in Settings → Applications.
How to turn off Wi-Fi on a phone without a screen (if the display is broken)?
If the screen does not respond to touch, but the phone turns on, try:
- Connect your phone to your computer and use the program Vysor or scrcpy for PC control.
- If there is access to USB debugging, turn off Wi-Fi via
ADBcommand:adb shell svc wifi disable - On iPhone You can try voice control via Siri (if the "Hey Siri" feature is enabled).
- As a last resort, remove the SIM card and use another phone for remote control (via a Google or iCloud account).
