How much Bluetooth does the phone battery consume?

Does Bluetooth drain the phone battery? All wireless technologies require energy, but there are various stories and theories about their energy consumption. Despite advances in Bluetooth technology, it is still a relatively common belief that turning off Bluetooth, WiFi, NFC, and other technologies can dramatically increase the phone's battery life.

Does Bluetooth drain the phone battery? All wireless technologies require energy, but there are various stories and theories about their energy consumption. Despite advances in Bluetooth technology, it is still a relatively common belief that turning off Bluetooth, WiFi, NFC, and other technologies can dramatically increase the phone's battery life.

Many users They are used to these things and old habits can hardly be abandoned. But is it really necessary to turn off Bluetooth and WiFi on the phone? Exactly how much battery power is wasted when not using Bluetooth but keeping it on? What about Bluetooth music playback and its impact on energy consumption?

To answer these questions, the Android Authority site has performed a number of experiments using several different phones, which we will discuss below.

How to perform the test

The first test is a typical battery drain scenario to discover Whether turning off Bluetooth will increase battery life. To do this, two sets of experiments were performed. In the first test set, the Bluetooth test is off, and in the next test set, the Bluetooth is turned on but left unused to check the results of both cases.

The first test itself consists of three cycles. The first cycle consists of 90 minutes of surfing, then 90 minutes of sleep mode, and then again 90 minutes of surfing. For the second cycle, the handsets are put to sleep for 16 hours, and in the third cycle, the first cycle is repeated.

In the second set of experiments, the use of Bluetooth is simulated to investigate the effect of Bluetooth on battery charge consumption. In this set of experiments, apart from 4-hour video playback, the modes related to Bluetooth off, Bluetooth on but without using it, and finally video audio playback via Bluetooth using the SBC audio codec have been investigated.

For these experiments, the screen brightness is set to 200 nits. Also, mobile internet, NFC and other features have been disabled and Wi-Fi is only enabled in the first scenario. Also, all the tables you can see below are based on the average of the results to increase the accuracy of the results.

Does turning off Bluetooth increase the battery life of the phone?

During the 26-hour test period, keep Bluetooth on and do not use it in the end It consumes 1.8% more energy than the battery. On average, select handsets consume 49.4% of their battery during the test when the Bluetooth is off, which is up to 51.2% when the Bluetooth is on.

There should be a slight difference between the handsets. Mention also tested. Huawei P40 Pro and Poco F2 Pro had the biggest difference between turning Bluetooth on and off with a charge difference of 3%. Meanwhile, the Galaxy S20 and the SuperSum Rymi have a slightly smaller difference between the two modes, showing just how little Bluetooth really has on battery life. For a closer look, you can see the chart below.

In any case, the tests performed Others prove the fact that if Bluetooth is turned on but not used, it automatically enters sleep mode. When the phone is turned on and you are using it, the phone Bluetooth looks for gadgets. So you do not need to worry about turning on or off the phone's Bluetooth before going to bed.

How much battery power does Bluetooth consume?

We proved in the previous section If Bluetooth is turned on but not used, it has almost no effect on battery consumption. But how much does battery consumption increase when we actively use Bluetooth? In the second series of tests, with a 4-hour video playback, the small difference in battery power consumption again draws attention.

A comparison between off and on Bluetooth off during 4-hour video playback shows that only 1.6% consumption is seen. We consume more battery. In other words, this result means that for the entire charging time of these phones, we will see an average charge difference of 6.6%. It should be noted that in this scenario, the phone is always playing video, which seems unlikely in the real world.

Battery charge consumption in three different modes when playing 4 hours of video

In this test, many differences were found between different handsets. The Galaxy S20 Plus has recorded the same result in both Bluetooth on and off. The worst performance is related to the X3 Superzoom Riley, which consumed 4% more power in 4 hours in two modes.

The reason for this difference is probably the software and hardware optimization of these phones. Although the difference in power consumption of any of these phones is not exactly the same, but in the worst case, there is not much difference.

  • Myths and realities of fast charging smartphones

Does using bluetooth headphones drain the phone battery?

BingMag.com How much Bluetooth does the phone battery consume?

Bluetooth is the most important use for headphones, so many users are concerned about increased battery power during such uses. The results of this study show that Bluetooth audio playback consumes the same amount of energy as speakerphone or wired headphones. On average, these phones consume only 0.2% more power when playing audio via Bluetooth. Meanwhile, the Galaxy S20 Plus and Poco F2 Pro did not record any significant changes in battery consumption during the 4 hours of video playback.

The main reason for this is the Bluetooth algorithms used by the processors. Digital Signal (DSP) is implemented in smartphones and can reduce the power consumption of this technology.

Last word

Although not all aspects of using Bluetooth were tested in this experiment, there is still information on how Bluetooth affects battery life. It gives us good. One of the most important results is that Bluetooth does not affect the battery life of the phone when it is not working. Therefore, there is no need to turn off the phone's Bluetooth while sleeping.

Most users will not notice an increase in battery power if they forget to turn off Bluetooth. Of course, if you want to prevent the phone from connecting to other gadgets unintentionally or you are worried about the security of your phone, turning off Bluetooth is recommended.

Finally, in answer to the main question of this article, we must say that Bluetooth in different situations It consumes very little power, so it's best not to worry about it.
