Do you turn off Bluetooth and NFC when not using them?
Bluetooth has become an integral technology for smart devices and cell phones. As a wireless adhesive that connects smart devices, it’s something most of us likely leave on all day when connected to headphones or smartwatches.
NFC is now also available on more and more devices. Not initially available on most low-end devices, it enables mobile payment and device coupling. It has become a different technology without which phones would feel ill-equipped.
Should you leave these radios on all day?
There is a case for turning off bluetooth when not in use. The security mind would argue that cranking provides potential attackers with yet another vector. Both Bluetooth and NFC discharge the battery in the background, albeit in a tiny, almost negligible amount.
Likewise, leaving the technology on is solid. Bluetooth has become an essential part of fighting the COVID-19 pandemic. The Exposure Notification API uses them to contact the trace and ensure that users are notified when they may have been exposed to the virus. Leaving Bluetooth and NFC just got more convenient, especially if you own wearables.
