Although current phones have improved a lot in energy efficiency, there are still small adjustments that can make a difference in battery life. One of the simplest and most effective is deactivate bluetooth when you’re not using it. It may sound like a advice from another era, but the truth is that it works.
Many people leave it on all day for comfort, to have wireless hearing aids, the smart watch or even the car, without noticing that habit drains energy little by little.
Why disable Bluetooth helps save energy?
There is the idea that keeping the bluetooth activated does not spend battery if it is not connected to anything. And although in part it is true, because the current versions use Bluetooth Low Energy (BLE) technology, which is much more efficient, There is still a consumption that accumulates with the passing of the hours.
Tests performed on different devices have shown that, keeping the active Bluetooth without connection, the phone can lose up to a 2 % extra battery in a single day. It may seem little, but if you add to other factors – high, constant notifications, mobile networks – that percentage can make the difference between arriving with 15 % load or running out of battery before getting home.
In addition, there is a situation in which this expense becomes more evident: when you are in places with many Bluetooth devices around. In a big city, your phone is constantly detecting signs of beacons, trackers and nearby gadgets. This activity makes cell radio work more, which translates into an additional consumption that you can clearly notice.
When to turn it on and when to turn it off

If you are going to listen to music with your wireless hearing aids, synchronize your smartwatch or connect the phone to the car, light it without problem. But once you finish, get it again. This simple gesture can give you additional autonomy hoursespecially if you usually spend a lot of time away or do not have a charger always by hand.
In fact, battery optimization experts include it among the basic tips to prolong the useful life of smartphones. As well as reducing brightness, activating savings or closing applications that consume in the background, Managing the use of Bluetooth consciously can become a habit that your battery will appreciate.

- In areas with high device density, turn it off, it prevents the phone from having it looking for and connecting, something that does faster the load.
- If your priority is to arrive with drums at the end of the day, each adjustment adds, and this is one of the easiest to apply.
In the end, it is not about turning off everything and living disconnected, but about applying a little common sense.
