Is it dangerous to have Bluetooth always on?

Our mobile phone takes advantage of all kinds of connections, be it the 4G or 5G connection, WiFi, NFC or Bluetooth. The latter is one of the most used by users because it is used to keep a device connected to the smartphone, such as a smart watch or bracelet. Hence, many bet on leaving it on constantly, although this is a very serious mistake that you should stop making.

In this post we are going to reveal the danger of not deactivating this technology, which is really useful, but it can also cause problems in the future. The problem that this entails is that your wearables may not receive information belonging to the terminal, so you must be the one who decides whether or not it is worth doing or not.

Is it dangerous to have Bluetooth always on

What happens when you leave Bluetooth on

As we have already mentioned and as you may know, Bluetooth connectivity allows you to establish a link between two or more devices to transfer files, listen to music in the case of wireless headphones or connect a smart watch to receive data. This has its advantages, but unfortunately it also has negative consequences that we will explore below.

Waste of battery

The first and most logical drawback is that with Bluetooth always on, energy consumption is constant. Of course, having more devices linked means more wear and tear, but even without them, the battery will be significantly reduced.

This can be detrimental in the event that the autonomy of your phone was already suffering from before. So turning off Bluetooth is more than recommended in this case. Otherwise, it is quite likely that you will not be able to enjoy the full capacity of the battery.

Bluetooth cybercriminal attacks

Among the main problems that arise when Bluetooth remains active are those related to hackers . These look for any way to access our data and this technology is ideal for it because they can take advantage of and attack the data of both devices.

The cybercriminal takes advantage of the connection to view the information and in the event that he manages to gain access to our mobile, he could control it or obtain personal data . A compelling reason to disable this property when not in use.

Security breaches

If you have a smartphone of a certain age, it is easier for attackers to access your device through Bluetooth. This is because previous generations did not boast of the Bluetooth 4.0 and 5.0 standard , versions in which to gain access to the terminal they need our permission.

In contrast, previous versions did not offer this option, but another person could connect without any permission involved. This generates security gaps that a hacker can squeeze as there is no barrier and the worst thing is that you would not even realize it at first.

Nonstop data

This is an issue that directly connects with the previous two and is that Bluetooth transfers data continuously without interference. The reason this happens is because the system must share the UUID , an identifier whose purpose is to allow the connection of other devices.

In the event that a user manages to get hold of this UUID, they would be in serious trouble, since the cybercriminal could locate the location of the mobile . Without a doubt, it is a facet that affects privacy and that must be taken into account.
