Owners of a device whose “blue tooth” feature is always on may encounter various problems without even knowing why. The Bluetooth logo also carries a secret message from the developers.
An always-on Bluetooth adapter threatens modern smartphone owners with hacker attacks, rapid battery wear and slower device operation. The iTechua portal writes about the nuances of using this module.
Bluetooth was once very popular in push-button phones. People were sending photos and music through this wireless module, which supports communication between devices from a distance of about 10 meters. Later its glory faded somewhat, because the Internet appeared for data transfer and it became easier and faster to send files through different storage possibilities, and now through the popular Telegram messenger. But the advent of smartwatches and a wide range of wireless headphones has made Bluetooth popular again.
So what are the dangers of Bluetooth?
Those who actively use Bluetooth, for example, sports enthusiasts or music lovers, know all its nuances and do not fall into any traps. However, most people do not even pay attention to whether the Bluetooth icon is active or not.
Moreover, a large portion of users do not know anything about this screen or see it by randomly scrolling on the screen (moving their finger on the screen). But that’s not the point, the fact is that many users always have Bluetooth in their smartphones, even if the wireless data transfer function is not used.
When the module is turned on, it waits to connect to another device. It is also in advanced search mode, which requires constant energy, which means it wastes battery power. Moreover, connecting to another Bluetooth device reduces the data transfer cost, but it is the fruitless search efforts that waste the battery reserve the most.
It’s worth noting that the always-on Wi-Fi module in your smartphone does the same thing; It searches for wireless routers and consumes energy to do so. Of course, it is very convenient to come home without the hassle of getting Internet from your home router, but if you want to save battery, turn off the Wi-Fi module outside.
Of course, this module is unlikely to completely drain your battery, but it will definitely force you to connect to the outlet more often. Each battery has its own charge/discharge limit (approximately 500 cycles), which means the battery will consume its energy storage capacity much faster than you expect and you will have to go to the workshop to replace the battery.
The second important point is security. Under certain conditions, you can connect to your smartphone via Bluetooth and do whatever you want. For example, access important information, make calls, or even read SMS. The more modern the version of Bluetooth, the less these risks are, but not completely; This should also be kept in mind and only turned on if you really need it.
Owners of weak budget smartphones can slightly speed up the device by turning off Bluetooth. The fact is that the operating system spends some of its resources on supporting the adapter.
As a result, experts recommend maintaining “wireless hygiene”. Most likely, no hacker will be able to break into your smartphone due to always-on Bluetooth or Wi-Fi modules, but why would you want to have a device that constantly wastes energy “nowhere” and causes premature battery depletion?
Hidden message in the logo
By the way, if you don’t know, this wireless protocol was created by Scandinavians Sven Mattisson and Jim Kardach, who worked on this technology in the late 1990s. The creators realized they needed to come up with something memorable that would also emphasize their national identity. Naturally, the conversation turned to the Vikings, and both engineers remembered the famous king of Denmark, Harald “Bluetooth” Gormsson, who, according to legend, had a problem with his teeth, but was famous not for that, but for uniting Norway and Denmark. .
Developers encrypted the name of the king in the logo. They combined the Norwegian letter “H”, which resembles our letter “F”, with the letter “B”. This is how the logo was created in honor of the famous Viking king.
