Technology is developing very quickly. One consequence of this is that advice or truths we thought we knew about certain technologies are no longer as true as they were a few years ago. We saw this a while back with some tips to extend your smartphone’s battery life. Tips that sometimes we dragged from the days when batteries were different. The same goes for another common tip that recommends turning off Bluetooth to reduce battery drain.
Actually the confusion turn off bluetooth or not It has its own reason for various reasons that get confused over time. But let’s unravel this thread through recommendations made by the smartphone manufacturers themselves and based on their analysis in specialized media Android control. His findings apply to both Android phones and iPhones.
And it is that disabling Bluetooth is useful for something, but not always for what people usually recommend. Let’s see the test results on battery usage and whether Bluetooth is disabled or not, the difference between having it off, on or in usewhere does the confusion come from and why it is worth turning off or not turning off Bluetooth on a smartphone.
Battery use and disable bluetooth or not
We said that in Android control they put to the test five smartphones Android 2020 to check what battery usage Bluetooth technology makes, very popular lately with wireless headphones, smartwatches and bracelets or wireless game controllers. Bluetooth battery is the reason your phone the last few hours? Devices used in the test Samsung Galaxy S20 Plus, Huawei P40 Pro, ZTE Axon 11, Xiaomi Poco F2 Pro D Superzoom Realme X3.
first test or test consisted of three loading cycles. First, 90 minutes of web browsing, 90 minutes of rest, and another 90 minutes of web browsing. They then left the phones lying around for 16 hours. And finally, the first cycle was repeated. second test consisted of playing video for 4 hours. With Bluetooth off, on but not in use, and finally with Bluetooth in use. And to avoid imbalances, they set the brightness to 200 nits on all devices, disabled mobile data and NFC and they left WiFi only for the first test.
results? In the first test saving on battery usage it was 1.8%. That is, with Bluetooth turned off, the phones consumed 49.4% of the battery when browsing the Internet. With Bluetooth enabled but not in use, consumption was 51.2%. Let’s go to, another 10 or 15 minutes of life useful on your phone if you are going to disable Bluetooth. It may seem like a little or a lot, it depends on everyone.
And with him bluetooth in use? In a test of playing four hours of video with Bluetooth turned off, 22.6% of the battery was consumed. With Bluetooth turned on but not in use – 24.2%. And when using Bluetooth – 22.8%. In this test, the people in charge say that each phone gave different results. That is each manufacturer makes its own improvements to use Bluetooth via Android.
As for explaining why the consumption of Bluetooth in smartphones is so low, the answer is: the worst part is taken by the connected device, be it a bracelet, watch or headphones. In addition, smartphones and other devices today often use Bluetooth Low Energy or Bluetooth Low Energy. It’s precisely designed to consume less battery while maintaining the same coverage.
Bluetooth Disable Confusion
In this moment. dowhy is it recommended turn off bluetooth to save battery? Although the analysis we have seen has its pros and cons, it is quite reliable. And we can be left with the conclusion that yes there is minimal battery saverbut hardly noticeable. In the test, the savings are between 10 and 15 minutes on a device that can run 5 hours with the screen on. If you’re okay, then go ahead. Or better yet, let’s see when to turn it off and/or when to leave it on.
reasons for leave bluetooth on:
- You have Bluetooth devices connected to your smartphone.
- In addition to being connected, you use them.
- You usually use them daily, although not always.
- Geolocation and sports devices consume less power.
At this last moment, if you use smart bracelets or watches, their battery lasts less when you deactivate Bluetooth on your smartphone. Apple, for example, says this on its official website: “If you turn off Bluetooth on the iPhone, Apple Watch consumes more power. For the best connection between the two devices, keep Bluetooth on your iPhone turned off.”
reasons for turn off bluetooth:
- No Bluetooth devices are connected to your phone.
- You won’t be using Bluetooth devices anytime soon.
One explanation for why we think turning off Bluetooth saves battery power is that this tip yes it is useful in case of wifi and mobile data. Almost all manufacturers recommend turning off the WiFi connection if you are not going to use it. And that you turn off mobile data if the coverage is bad. It is these two technologies those that drain the battery the most next to the screen. And since Bluetooth technology is technically very similar to WiFi, hence the confusion.
So should we turn it off or not?
Now we know what happens to battery usage when Bluetooth is turned off. We also know where this myth came from and what time we should turn Bluetooth on or off. But there is Another reason so that this wireless technology is not activated. And it has to do with security.
The US Federal Communications Commission, the agency responsible for regulate communications cable, radio, television, satellite, Internet and other wireless technologies, contains a number of recommendations on the use of WiFi and Bluetooth from a security point of view. Specific, FCC recommends turning off Bluetooth if you are not going to use The reason is that this technology can be used to scan connected devices or get information from the phone if it can connect via Bluetooth.
Another FCC recommendation is that we use Bluetooth in stealth mode instead of the normal visible mode. In the second case, the device can be detected by outsiders. And while Bluetooth technology and your phone have security measures in place, all precautions are small.
