Are you still turn off the Bluetooth while using Xiaomi Mi band 4?

Are you still turn off the Bluetooth while using Xiaomi Mi band 4?

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.

Q9 Smart Watch

 

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

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?

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.

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.
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.
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!
