I remember the last time I tried Mi Band 4 and found that it has improved many basic items, such as screen brightness, area for displaying information, vibration intensity, tightness with the wristband, waterproofness, remote control music, etc.

Some basic items of Mi Band 5 have been slightly improved, and the more difference is the addition of functions and supported sports.

Let’s first refer to the specification comparison. The power and usage time are less than that of the fourth generation, but 14 days is quite a long time.

Can wristbands be shared?

The wristband of Mi Band 4 can be used for Mi Band 5, but if it is marked as the wristband of Mi Band 5, it cannot be used for the fourth generation.

The reason is not because of the different sizes, but because of the different widths of the grooves of the BP5324A . After comparison, we can see that the grooves of the Mi Band 5 are wider, so the side of the wristband is also wide, so it is just plugged in. It does not enter the bracelet 4, but the relatively narrow fourth-generation bracelet can still be stuck on the bracelet 5.

Simply put, the old wristband can be used for new rice grains, but the new wristband cannot be used for old rice grains.

No need to pull rice grains for charging

The Mi Band 5 has changed the charging method to a magnetic type. Although it still needs a dedicated charger, it is not necessary to remove the rice grains like the Mi Band 4. It can be charged directly on the wristband, which is much more convenient. .

Hey, the charging contacts look very similar, can I just buy the charging head of the Mi Band 5 to charge the Band 4?

Hmm...if you have a way to get the charging head to suck and hold it in place, yes.

If you take a paper clip and touch the charging head of Xiaomi Mi Band 5 near the charging point, you will find that there is magnetic attraction, but the Mi Band 4 does not have any rice grains, so the charging head cannot be fixed. The problem is here, otherwise according to hand pressure Live and test, it can be charged when it is connected to the power...

Is the screen brightness better in sunlight?

The digital specifications of the screen brightness of Xiaomi Mi Band 5 are relatively high, but the difference is not obvious to the naked eye (my fourth-generation bracelet is very rarely worn, so there is no need to consider the problem of brightness decline). Having said that, in fact The brightness of Xiaomi Mi Band 5, whether it is a black background or a white background, can be seen in the sun. And the screen cover is flat, and there is no reflection interference.

Has the vibration intensity changed?

I really want to be a little difficult to express, let's compare the vibration of the incoming call notification. The vibration force seems to be a little bigger, and it feels the same when you wear it on your hand, but everyone's perception is different, you can still refer to the video to see if it looks ideal.

Is the font and area of the displayed message different?

Yes, for text messages, Mi Band 4 can display 40 characters, and Mi Band 5 can display 45 characters, one more line. But the font size is still the same, and the built-in settings cannot adjust the displayed font size.

LINE's call notification?

Xiaomi Mi Band 5 is equipped with an Android mobile phone, and the default is still unable to notify the incoming call (iPhone can), but it can be solved through a third-party program. Users of Mi Band 4 can also try it out.

Go to Google Play to download and install "Notify & Fitness for Mi Band"

After opening, there will be a Bluetooth connection with the bracelet, as well as the steps to allow permissions such as self-start, notification, etc., follow the steps first, so as not to miss the notification. Then click the envelope icon in the top row to enter the application setting page, and then select "Call".

Click on "Call", you can see a lot of options, whether you need to open it or not, you can study slowly, but the key is to open "Voip call", after setting it, you can try it, you should find that on the bracelet You can now receive notification of incoming calls from LINE.

Phone disconnect notification?

This Xiaomi Mi Band 5 also has no built-in, and relies on a third-party APP, like the above set of "Notify & Fitness for Mi Band".

Click the hamburger Menu icon in the upper left corner and select "Bracelet Settings". Swipe down and you will see the setting of "lost connection", just open it. Similarly, you can also set the notification after the connection is restored. However, I found that sometimes I left the disconnection, and when I came back to the mobile phone, I had to turn on the mobile phone screen and the bracelet would automatically restore the connection. Do you have any solutions?

Heart rate accuracy?

This time, Xiaomi Mi Band 5 advertises that the heart rate accuracy is 50% higher than that of the previous generation. I don't have a heart rate belt strapped to my chest, so I used the Apple Watch as a comparison, and the measurement results after pressing start at the same time are quite close. It seems that the heart rate accuracy of the Xiaomi Mi Band 5 is not bad.

The charging becomes more convenient, the screen is slightly larger and the brightness is increased. It is a very practical change. Other basic functions such as settings and notifications do not seem to be very different from the Mi Band 4. However, there are still many internal updates, such as the dial and remote control. Taking pictures, more indoor sports such as elliptical machine and skipping rope, as well as health functions such as stress detection, recording sporadic naps, etc.

In addition to being cute, the surface can be customized

When the Xiaomi Mi Band 5 was released, it was mentioned that it provides more than 100 well-known two-dimensional portrait surfaces, including SpongeBob SquarePants, Conan, Evangelion... etc. This is also not available in the surface store of the Mi Band 4, but Taiwan does not Do you know if it can be downloaded or not, will there be copyright restrictions? Ask at the press conference.

After my Chinese version of Xiaomi Mi Band 5 is connected to my mobile phone, I only see the surface of SpongeBob SquarePants..

After changing the non-black surface, I found the size of the display screen (the first time I thought it was not very big...). Looking at the design, some patterns squeeze the space of the text, and some numbers look small.

The built-in surface can be customized, which is also added to the Mi Band 5. You can choose what small items to display on the surface, weather, heart rate, step count, calories, battery... and so on.

Remote control photography is remote control photography

Xiaomi Mi Band 4 added the function of remote control music. In this generation, remote control photography is added, but it is really a simple remote control photography. After turning on the camera first, then pressing the shutter remotely with the wristband to take pictures. Video recording is included, and remote switching between front and rear cameras is not included.

More health detection

Health detection has also added a lot of things, including women's health records during menstrual period, stress monitoring, breathing training, detection of PAI vitality index for a week, etc.

Stress detection and breathing training are basically the same. Use heart rate variability data to clip some calculation models to infer pressure. If you feel nervous, do a set of rhythmic deep breathing with breathing training, adjust it, office workers need it every day~

After getting through the annoying pressure, Xiaomi Mi Band 5 also provides a record called "PAI Vitality Index", which is called personal physiological activity data.

It is an index calculated based on heart rate, daily activity frequency, and personal physical data. Simply put, it is a health data that is moving depending on whether you are alive or not. The above is helpful for reducing cardiovascular disease.

This is a project that is detected every day and accumulated for a week to see if you have reached the goal. As long as you do some activities that increase your heart rate, you will get PAI points, and it will also recommend you what activities to do. It is a relatively friendly and approachable health steward Bar.

Sports test... I can't do it alone, I will arrange it and hope to have a chance to shoot.

Seeing this, unless your Mi Band 4 has a problem with the power and screen, people who are not doing indoor exercise (huh? I mean the gym kind) may not necessarily need to switch to Mi Band 5. But it still has some attractive points, such as charging without plucking rice grains, recording noon naps, PAI index, which is also positive, and recording skipping rope is very practical... etc., but because the built-in power becomes less , it may still depend on your usage, and then see if the 14-day battery indicated on the Mi Band 5 is sufficient.
