The bluetooth connection of our iPhone is really important when it comes to our phone working exactly as it should. A connection that we can disable, yes, but the question is why? On the one hand we can speak of battery, on the other of safety, even of privacy.
But Do we really gain anything by turning off the bluetooth of our iPhone? The truth is, by weighing the advantages and disadvantages, we lose. Quite, in fact, because our iPhone’s bluetooth connection is specifically designed to work permanently.
Many advantages and a small inconvenience
Let’s focus on something. When we activate the airplane mode on our iPhone, by default the bluetooth connection is active. This is Apple’s approach to this wireless radio connection. And there are reasons, because the bluetooth connection on our iPhone takes care of connecting and transferring data with our Apple Watch, connecting with the AirPods every time we use them, locating our AirTag accessories, turning off the always-on screen. of the iPhone 14 when leaving the room with our watch, to allow us to locate a lost iPhone, even when it is turned off, and a long one etc.
One of the main reasons for turning off bluetooth is battery drain. It is true that there is a battery consumption, but we are talking about 1% per day. Totally negligible consumptionespecially taking into account the advantages that this active connection offers us.
Another of the reasons cited for turning off the bluetooth of our iPhone is privacy. It is true that in a Xiaomi device, leaving the Bluetooth of your Xiaomi mobile on all day can bring you problems in terms of privacy. These devices constantly broadcast the device’s Universaly Unique Identifier (UUID) via Bluetooth, but iPhones don’t.
As Apple exposes in this support documentLow-energy Bluetooth on our iPhone uses address randomization drastically reduce the ability to follow a bluetooth device for a while by frequently changing direction Of the device. Only when we connect to a device with our iPhone and both exchange the identity resolution key, that device can resolve the private key to establish the connection.
So, and as we started by saying, what is the advantage of turning off the bluetooth connection on the iPhone? We can only talk about that 1% battery. The disadvantages are, however, not being able to use the AirPods, forcing our Apple Watch to use Wi-Fi or mobile data networks and preventing us from locating a lost device in case of need. turns out leaving our iPhone’s Bluetooth on all day is a good idea.
