Switch Off Phone Tracking: Many smartphone users believe that if their smartphone is switched off, their location cannot be tracked. However, even a switched-off smartphone can reveal your location.

Switch Off Phone Tracking: Smartphones have become an essential part of our lives today; wherever we go, our phone goes with us. Consequently, people often switch off their phones for security or privacy reasons, believing that once the phone is off, no one can track their location. But this is not true, as your phone can still reveal your location even when switched off. There are several ways to track a location even without internet access.

The phone doesn't fully 'sleep' even when switched off.

When you switch off your phone, you might think it has shut down completely, but that is not actually the case. Even after the phone is turned off, certain internal components continue to operate on very low power—a state known as "low-power mode." As a result, the phone's Bluetooth and certain sensors remain active, even though the screen is dark and the device appears to be off. Apple was the first to implement this technology robustly in its iPhones, and Google subsequently introduced it for Android phones as well. Essentially, when your iPhone or modern Android phone is switched off, it continues to emit a hidden Bluetooth signal to its surroundings. For instance, if your switched-off phone is nearby and another active iPhone or Android phone passes by, your inactive phone sends a secret signal to the active one. That active phone then transmits your inactive phone's location to the company's server via the internet, allowing the precise location of your switched-off phone to be determined.

New Bluetooth and chipset technology

Older phones used to become completely inactive when switched off, but modern smartphones utilize a technology known as "Bluetooth beacons." Furthermore, the phone's core chip is designed to transmit faint signals for months without draining the entire battery. This is why the phone can be located even if it is stolen or switched off. Even if a phone lacks this specific technology, the police can still determine the last known location of a switched-off phone; this is because, while powered on, the phone remains connected to nearby mobile towers—a process known as triangulation. Once the phone is turned off, the mobile service provider records the details of the tower to which the phone was last connected, providing an estimate of the area where it was switched off.

How to avoid this

If someone wants to ensure their phone cannot be tracked at all after being switched off, there are only two options: physically removing the battery—which is not possible with modern phones—or placing the phone in a specialized pouch or bag that blocks all radio and Bluetooth signals from escaping.
