Is leaving Bluetooth on a security risk?
Some say that Bluetooth technology is dying out, but that is far from the truth. But while Bluetooth allows for an automatic and wireless connection, it can also be a major security risk, as it leaves data vulnerable to interception. Hackers often use a Bluetooth connection to spread malicious files and viruses.
Does leaving Bluetooth on drain battery?
Many people recommend disabling Bluetooth on your phone to get better battery life. In our testing, having Bluetooth on but not actively connected to a device used a negligible amount of battery power over several hours.
Why should you turn off your Bluetooth?
Turn Bluetooth off when not in use. Keeping it active enables hackers to discover what other devices you connected to before, spoof one of those devices, and gain access to your device.
Why you shouldn’t use Bluetooth?
In fact, at this year’s DEF CON researchers showed off the ability to use Bluetooth to identify vulnerable digital speakers. Once identified, hackers could take control of the devices and force them to play “dangerous” sounds that could lead to hearing loss in anyone unfortunate enough to be nearby.
