Bluetooth is a popular wireless technology that allows connecting devices such as headphones, speakers, keyboards, smartwatches and sharing data between devices. However, keeping Bluetooth on even when not in use can bring many potential risks and harms.
Protecting equipment from the risk of attack
When you are Bluetooth enabled, your phone or computer can always be detected by other surrounding devices. If left unused for a long time, the device will easily become the target of bad guys. They can take advantage of security vulnerabilities to break in, steal data, track you, or remotely control some functions.
Saving batteries and increasing device performance
Bluetooth will continuously search and wait to connect to surrounding devices when turned on. This activity, although underground, still consumes system resources and battery energy, especially on smartphones or laptops. turning off Bluetooth when not in use will significantly reduce battery consumption, contributing to prolonging the device's usage time during the day and increasing battery life in the long term.
Avoid signal interference and connection errors
Bluetooth works on the same frequency as Wi-Fi (2.4GHz), so if turned on continuously, it can signal interference, slow down Wi-Fi connection or affect other wireless devices. In addition, when Bluetooth is always on, the device can automatically connect to an older speaker, headphone or device that you do not intend to use, causing trouble in some situations.
Preventing unwanted data sharing
In public places, there may be cases where others intentionally send files, images or malware via Bluetooth. If you do not pay attention and accidentally accept, the device may be infected with a virus or personal data leakage. Turning off Bluetooth when not in use is a simple but effective way to prevent this risk.
