Many friends in the process of using the Xiaomi mi band 4 or Mi band 3 is quite worried about one thing: the mobile phone Bluetooth is often turned on, will be too power-consuming, so the very useful Mi band unlock function, music control function, even massage notifications in the Mi band has been turned off directly, what a pity. Let's take a look at Bluetooth 4.0 and decide whether to turn off Bluetooth!

Although Xiaomi Mi band 4 already supports Bluetooth 5.0, most smart band and smartwatches on the market support Bluetooth 4.0 and above. So today, we talk about Bluetooth 4.0.

1. Bluetooth is on all the time. Will it cost a lot of electricity?

No, Bluetooth 4.0 on the phone is for low power consumption.

2. Why can only mobile phones with Bluetooth 4.0 or above be configured to use Xiaomi Mi band?

Because the Mi band use Bluetooth 4.0 BLE technology, the mobile phone must be adapted to the corresponding Bluetooth module to establish a normal connection, mainly in order to save power on the smart bracelet.

3. What is Bluetooth 4.0 BLE technology?

Bluetooth low energy consumption (BLE) technology is a low-cost, short-distance, interoperable wireless technology, working in the license-free 2.4GHz ISM radio frequency band. It has been designed as an ultra-low power (ULP) wireless technology from the very beginning. It uses many intelligent means to minimize power consumption.

4. After saying so much, I still feel like I'm charging for Bluetooth.

All right, let's turn on your phone switch and see what else you've turned on besides Bluetooth: generally speaking, turn on GPS, turn on WiFi, turn on the network location service, even make and answer calls where the service signal is bad. Using the 3G\ 4G network, the brightness of the display screen will be adjusted to the highest level, which will greatly consume the power of the mobile phone. The amount of electricity consumed by Bluetooth is really negligible.

5. No, I must turn off my cell phone Bluetooth when I use my Mi band 4!

It is also possible to turn on Bluetooth to establish synchronization only when you need to view motion data. Do you really want to do this?

6. What are the functions of the Mi band that cannot be used after Bluetooth is turned off?

Unlock your phone, call reminder, message reminder will fail, other such as vibration alarm clock, motion data records are not affected. But we strongly do not recommend it.

7. Can the Mi band work alone without the phone, such as going out for a run only with a smart bracelet?

Of course, it can store a week's worth of motion data separately, and when the Mi band is close to the phone, the APP on the phone is automatically synchronized, which is very convenient.

8. How far is the effective distance for unlocking the phone screen?

It can be unlocked within a range of 2 to 3 meters, and we do not think it is good enough. Mi band team are considering reducing the unlocking distance of the bracelet in order to better protect the safety of the mobile phone. Bluetooth signal is fluctuating, the unlock distance is far and near is normal, and there is a certain direction, for example, if you put the bracelet behind you, the signal may be blocked by the body and can not unlock the screen lock of the mobile phone.

9. If a mobile phone be connected to a smart band and can it be connected to a Bluetooth speaker, Bluetooth headset or car device at the same time?

Yes, it is possible for the above mobile phone Bluetooth to connect to many of the above devices at the same time.

Read at here, do you no longer have a misunderstanding about Bluetooth? Just turn on the Bluetooth in your mobile phone and enjoy the convenience that Xiaomi Mi band 4 brings to our lives!
