Your iPhone constantly tracks your physical location using a combination of GPS satellites, Bluetooth beacons, and local Wi-Fi networks. It feeds this data to Apple Maps for navigation, to the Weather app for local forecasts, and to third-party apps like Uber or Yelp. If you value your privacy, or if you simply want to dramatically extend your battery life while traveling, you can turn this tracking off.
Apple provides incredible, granular control over your location data. You can choose to obliterate the GPS signal entirely (the master kill switch), or you can surgically block specific apps from seeing where you are.
Method 1: The Master Kill Switch (Turn Off All Location Services)
If you want to go completely off the grid, you can turn off the iPhone’s GPS hardware entirely. This is the fastest way to save battery, but be warned: doing this will break Apple Maps, prevent you from finding local restaurants, and stop you from geotagging your photographs.
- Open the main iOS Settings app (the grey gear icon).
- Scroll down and tap on Privacy & Security (it has a blue icon with a white hand).
- At the very top of the screen, tap on Location Services.
- You will see a master toggle switch labeled “Location Services.”
- Tap the switch to turn it Grey (Off).
- A warning pop-up will appear. It explains that Location Services will be completely disabled across all apps, but will temporarily turn itself back on if you call Emergency Services (like 911).
- Tap Turn Off to confirm.
Your iPhone is now blind to its physical location.
Method 2: Surgical Blocking (Turn Off Location for Specific Apps)
Most users do not want to break Apple Maps; they just want to stop Facebook, Instagram, or a random flashlight app from tracking them. You can revoke GPS privileges on an app-by-app basis.
- Open Settings > Privacy & Security > Location Services.
- Ensure the master switch at the top is turned ON.
- Scroll down the screen to see a massive list of every single app installed on your phone.
- Find the specific app you want to block (e.g., Facebook) and tap it.
- You will see a list of access options. Select Never.
That specific app can no longer access your GPS data, but your navigation apps will continue to function normally.
Method 3: The “Precise Location” Blur
Sometimes, an app genuinely needs to know roughly where you are to function, but it absolutely does not need to know your exact street address. (For example, a weather app needs to know what city you are in, but it doesn’t need to know which bedroom of your house you are standing in).
Apple allows you to artificially blur your location data, feeding the app a generalized 10-mile radius instead of a pinpoint GPS coordinate.
- Open Settings > Privacy & Security > Location Services.
- Tap on the app you want to restrict (e.g., The Weather Channel).
- Ensure the access is set to “While Using the App.”
- Look at the bottom of the screen for a toggle switch labeled Precise Location.
- Turn this switch Grey (Off).
The app will now only receive your general city/zip code data, drastically improving your privacy while allowing the app to remain functional.
Method 4: Stop Sharing Location with Friends and Family
If you have previously allowed a spouse or friend to track your physical movements using the “Find My” app or iMessage, turning off GPS will make it look like your phone is dead or broken. You can quietly stop sharing your location with them without turning off your GPS hardware.
- Open the Find My app.
- Tap the Me tab at the bottom right corner of the screen.
- Look for the toggle switch labeled Share My Location.
- Turn it Grey (Off).
Your friends will no longer be able to track your dot on their map, but you can still use your GPS for your own personal navigation.
