Bluetooth Myths: People are mistaking rumors about Bluetooth for the truth. For instance, many believe that keeping Bluetooth turned on drains the battery quickly; however, the reality is that it has a negligible impact on battery life.

Bluetooth Myths: Gone are the days when you had to connect a cable from your computer to your smartphone just to listen to music. Now, neither do earbuds require a cable to connect to a smartphone, nor do controllers need one to link up with a gaming console. Wired connections now seem like relics of the past. All of this has been made possible thanks to Bluetooth connectivity. Because of Bluetooth, devices are more interconnected than ever before. From smartphones to smart homes, Bluetooth is being utilized everywhere. However, amidst this widespread adoption, several rumors regarding Bluetooth have also circulated among the public—rumors that are completely unfounded. Today, we are going to debunk some of these common myths surrounding Bluetooth and reveal the actual facts behind them.

Myth: Bluetooth Earbuds Cause Brain Cancer

Many people believe that using Bluetooth earbuds can lead to brain cancer. While it is true that Bluetooth devices emit a certain amount of radiation, there is absolutely no evidence to suggest that this causes brain cancer. Bluetooth earbuds emit non-ionizing radiation. This type of radiation does not possess enough energy to strip electrons from atoms within human cells. In addition to Bluetooth, Wi-Fi and radio waves also emit similar forms of radiation, and to date, there is no evidence indicating that these have any adverse effects on the human brain.

Myth: Keeping Bluetooth On Drains the Phone Battery Quickly

If you have heard that keeping Bluetooth enabled on your phone or other devices causes the battery to drain rapidly, that notion is entirely incorrect. Keeping Bluetooth turned on consumes very little battery power. An earlier test revealed that after keeping Bluetooth continuously active for 26 hours, the battery level dropped by a mere 1.8 percent. Moreover, newer versions of Bluetooth technology have since been introduced that consume even less battery power. However, keeping Bluetooth continuously enabled poses a risk of certain threats, such as Bluejacking.

Myth: Bluetooth devices have a limited range.

Many people claim that Bluetooth devices have a limited range—meaning that if the distance between two Bluetooth devices becomes too great, the connection drops. This assertion is not entirely accurate. In reality, smartphones, headphones, and wearables typically utilize Bluetooth Class 2. To minimize power consumption, its range is limited to 33 feet. There is also a second standard known as Bluetooth Class 1, which is used in high-end headphones, industrial laptops, robotics systems, ECG monitors, and similar devices. Its range extends to over 300 feet.
