Turn off Bluetooth to save battery? It might not make a difference..

A battery management is one of the daily challenges in the life of any holder of a modern mobile phone and, with electronic devices being increasingly connected to each other, the Bluetooth connection also becomes increasingly necessary to make the “bridge” between different gadgets.

There are those who choose to have Bluetooth always activated and, on the other hand, who choose to turn on only when this connection is needed and turn it off as soon as possible – arguing that they do it to save battery.

However, is there real gains for battery autonomy to be constantly turning Bluetooth on and off the phone? Well, according to an analysis of android Authority websiteit seems to make little sense.

The publication tested this hypothesis in 2020 with five different mobile phones – Samsung Galaxy S20 Plus, Huawei P40 Pro, ZTE Azon 11, Xiaomi Poco F2 Pro and Realme X3 Superzoom – and found that, on average, battery consumption was only 1.8% higher than when Bluetooth is off.

With the natural advancement of technology and improved energy efficiency of mobile phones at hardware and software level, it is natural that current mobile devices are even better at reducing the impact of Bluetooth connection on battery autonomy.

The convenience of having Bluetooth always enabled means you can connect your phone to the car, headphones and wireless speakers with fluidity, without constantly going to the settings panel to enable and disable this functionality.

This convenience is even highlighted by Apple in one of its customer support pages, noting that some of the most useful features of your products are only available by enabling Bluetooth (and Wi-Fi) connection.
