How to charge a fitness bracelet? Recommendations and ground rules

The update of the legendary line caused not only delight among fans, but also many questions. How justified is the transition from three to four? Has the battery life of Xiaomi Mi Smart Band 4 increased? The younger "brother" had serious problems with charge control. Frequent notifications, training mode, interval heart rate measurement and other functions quickly reduced precious percentages, and it was necessary to use the power source so that the device did not discharge to zero.

The manufacturer increased the battery capacity of the four to 135 mAh. The previous model was equipped with a 110 mAh battery. Is this update enough for a power-hungry OLED display with a relatively large screen? Let's figure it out in practice.

Charging the bracelet

In the basic package, the package with the Mi Band 2 bracelet contains:

1. The bracelet strap is made of high-quality soft material, pleasant to the touch.
2. A tracker inserted into a special groove on the strap. There it is tightly fixed and the risk of it falling out is minimal.
3. The “charging” itself is a cable with a USB plug on one side and a compartment for inserting a tracker on the other.

It’s worth saying right away that the three LEDs (for version 1s, version 2 has a display screen) available on the tracker perform a variety of functions, but as for the charge of the device, they are the ones that indicate its level. One LED on - 30%, two - 60%, three - 100%. This display system greatly simplifies the life of the device owner.

Statistics show that one charging procedure is enough for the bracelet to work for about 1 month. A large number of its synchronizations with a smartphone and intensive use of the active mode during excessive physical exertion can cause faster discharge. Such figures seem disproportionate when you consider how long it takes to charge the Xiaomi Mi Band 2 - about 2 hours.

Charging the device is quite simple:

1. You need to remove the tracker from the compartment on the strap.
2. Then you need to turn the contacts inside the compartment on the USB charging cable and insert it, fixing it tightly.
3. The cable is connected to a free USB port on the computer or to a power outlet via a special adapter.

Check contacts

If the Mi Band is not charging, first check the contacts of the tracker. As practice shows, for some reason the contacts on Xiaomi bracelets oxidize quite quickly. Most likely, the reason is that the capsule is not securely fixed in the strap and, as a result, moisture enters there, oxidizing the contacts, as a result of which the bracelet stops connecting to the cable. Therefore, they need to be cleaned, while doing everything very carefully, without using abrasive materials or any chemicals. In addition, you need to clean the contacts on the charging cable itself, which comes with the bracelet. This should be done with a soft cloth, after lightly moistening it with alcohol. After completing the cleaning, check whether the problem has been resolved - whether the bracelet turns on and whether its energy is being replenished. If your Xiaomi Mi Band 2 or Xiaomi Mi Band 1s bracelet still does not charge, proceed to the next step.

How to charge Xiaomi Redmi Airdots wireless device

To understand how to properly charge your Airdots, you need to understand its charge indication system. The percentage of the current charge of the headphones can be seen on the screen of your smartphone, but the amount of charge of the box itself is very problematic to understand.

To recharge Xiaomi headphones, you need to insert them into the charging box. It is impossible to mix up the left and right earphones, since they simply cannot be inserted into the wrong places.

You can't go wrong with headphones inserted into the box.

All you have to do is connect the micro USB charging cable with one end into the charging box, and the other into the USB port of the charger, PC or tablet.

Connect the cord to the micro USB connector

During charging, both the box and the headphones light up with a red indicator.

While charging, the headphones glow red

When the case is charging, it will stop glowing red and you can turn it off. The average charging time for Xiaomi Redmi Airdots is within 1.5-2 hours.

The box glows red while charging

On some headphone models, when the box is recharged, the color of the indicator will change from red to white.

How to do without a “native” device

Although the bracelet's charging cable is of high quality, it may stop working over time. If you don’t have a new cord yet, but the device already needs to be charged, you can do without it. This does not require any special effort, just follow these steps:

1. Take any working USB cable.
2. Expose the black and red wires.
3. Press them tightly to the contacts of the tracker capsule.
4. Connect the cable to the computer connector.

It must be remembered that this method is dangerous: if you do something wrong, the device will fail, and it can only be used as a last resort.

This is how charging is done without the original cable

The process and regularity of charging the gadget

After the release of the new bracelet from Xiaomi, consumers wanted to know how much charge the Mi Band 3 holds. Compared to Band 2, the previous model.

It has a larger battery capacity (110 mAh versus 70 mAh), which is why hopes were pinned on the new device that it would have greater autonomy and hold a charge better.

However, when using basic functionality and disabling options such as constant application notifications, a device charged to 100% lasts for 2-3 weeks of wireless use.

Let's look at how to charge the Xiaomi Mi Band 3 bracelet. The device comes with a USB cable, one end of which is inserted into the corresponding socket on it, and the other is used to connect to the charge source.

There are 3 ways in total:

• Using the charger included with the bracelet and connected to an outlet similar to similar devices for phones;
• By connecting the USB port on one side to the capsule, on the other to the connector of a computer or laptop;
• Using PowerBank - the manufacturer evaluates this method as the most preferable due to the supply of low current (5 V). Owners note that this method also reduces the rate of charge consumption, so the device can operate for a longer time without recharging. Using PB and a USB cable, you can also charge other devices - smartphones, players, etc.

If you are just going to buy a device, you need to know that devices arrive in stores discharged. The first time after purchase, charging continues for two hours.

When you connect the device to current, you can recognize the charging process in progress by the Charging inscription on the display. Upon completion of the operation, the inscription will change to Fully charged.

How long does it take to charge

Exactly how long it will take to fully charge the device depends on the battery capacity, as well as the specific model. On average, this process takes from 2 to 4 hours. Many devices do not have special protection against overcharging, therefore, the manufacturer does not recommend leaving them in a power outlet for a long time. Failure to follow these rules can quickly put the bracelet out of working order and significantly reduce the battery capacity (we will see this problem in the form of a quickly discharging battery).

Advice! To extend the life of the fitness tracker, the manufacturer recommends that you carefully study the documentation before use.

Mi Band 2 features

This fitness bracelet has wide functionality and therefore can be used in various cases.

Thanks to step counting, you can use Xiaomi Mi Band 2 for running and sports. The built-in accelerometer and gyroscope are responsible for this function. They determine the movements and movements of the device in space, and the software recognizes steps from all this activity and counts them.

Another opportunity that uses these functional elements is a smart alarm clock. In this mode, the bracelet analyzes the phases of sleep. The alarm goes off when the body is ready to wake up.

How does Mi Band 2 detect sleep stages? Similar to steps - this uses the built-in accelerometer and gyroscope. In the rapid phase of sleep, when the body can wake up alert and rested, the body moves a lot. In slow mode, the body practically does not move. The bracelet detects when its sleeping owner begins to move a lot - that is, enters the REM sleep phase - and turns on the alarm.

Another function of the bracelet is heart rate detection. The Mi Band 2 heart rate monitor uses technology to analyze the light transmission of human body tissue to calculate your pulse. To count your heart rate, you need to press the corresponding button in the Mi Fit application.

The display displays notifications from programs, time, during calls - the contact name, as well as some other information, including the measured pulse.

Among the capabilities of the Mi Band 2, which can be expanded by installing third-party applications, are a stopwatch, a timer, analysis of movements in training for certain sports, and much more. Of course, the bracelet can be used with various programs like Sleep as Android or Runtastic for tracking physical activity - if the user needs it and the capabilities of the standard companion application are not enough.

Consequences

There is an opinion among users that using an accelerated battery replenishment cycle leads to rapid wear. To date this has not been proven. In addition, manufacturers and scientists are constantly improving technology and chargers, which should automatically turn off QC mode when overheated.

So, in 2022, the next version from Qualcomm was presented – Quick Charge 4+. According to the manufacturers, the 2750 mAh battery will be half charged in 15 minutes.

And then, what difference does it make how quickly your battery can “disappear” if in a couple of years your phone inevitably becomes obsolete and requires replacement.

But Xiaomi does not recommend using the QC adapter with conventional devices where there is no fast charging icon on the screen. In this case, an increased voltage or current at the output will really ruin your gadget and it will stop turning on.

Why it won't charge, probable problems and ways to solve them

During operation, some difficulties may arise with charging and use:

• the bracelet is not charging, that is, the corresponding indicator does not light up;
• the device incorrectly displays the current charge level;
• the gadget does not turn on even after charging;
• The tracker turns off abruptly when there is still battery charge.

You can solve problems in the following ways:

• First of all, it is recommended to restart the device. Often problems are software in nature rather than hardware;
• if this does not help, you can try to untie the bracelet from the smartphone to which it is connected, and then reboot again;
• if the problem cannot be solved, you need to contact a specialized workshop for diagnostics. The battery may need to be replaced;
• try using another charger that matches the parameters, since the problem may be with it, it simply does not charge the gadget.

It is believed that problems with incorrect charge display can be solved through a software update, that is, by flashing the bracelet. Sometimes this really helps, but it is strongly not recommended to do it yourself.

If the bracelet is still under factory warranty, it is recommended to contact the store and use it. However, it is worth remembering that using an unsuitable charger may result in the case being considered out of warranty. Subsequent repairs, if possible, will be carried out at our own expense.

Video instruction

Have you ever encountered any sports bracelets before and just reading it is not enough to understand the intricate wiring and straps? In this case, check out our video, which describes in detail all the first steps with the new Mi Band 2 and the entire process of charging it.

Visually perceived information will help you almost instantly understand the intricacies of the fitness bracelet, and will make further work with it comfortable and easy.

It has a non-standard charging port with a special adapter that comes included. The device holds a charge from a month to three. And with such a long break between charges, it will not be difficult for many to lose the original USB charging adapter. While the adapter is not lost, connect it to the USB port and use a tester to see where the plus and where the minus are. I’ll show you where each contact is from different angles:

There is nothing fancy in the adapter, except for direct wiring from the plus and minus of the USB port with spring-loaded contacts. So if the adapter is lost, just connect 5 Volts to the plus and minus of the device.

Simply throwing wires onto the device, and even holding it while waiting for it to charge, is inconvenient. Therefore, you can make a small device from a regular miniUSB cable.

Using pliers, we straighten the outer casing of the miniUSB connector, the contacts became available to us. Plus on one edge, minus on the other (if you put the contacts up and look from the side of the connector, then the plus is on the left, the minus is on the right). And it’s better to tear off the three central ones altogether, in order to avoid shorting either 5V or minus to them. the outermost ones can be slightly bent upward.

Now you just need to fix the connector in a horizontal position and place the contacts on top of the contacts to charge the device. The procedure is a jewelry one (watch the video at the end), since balance is difficult to find, but still doable. The main thing is not to reverse the polarity! It’s better to sign both here and there at once, so as not to get confused.

Setting up the Xiaomi Mi Band 2 fitness bracelet

Setting up the device is quite simple.

How to turn on Xiaomi Mi Band 2?

The fitness bracelet turns on automatically. It must be fully charged (this will take approximately 1.5 hours) via the USB connector of the computer from the cable that comes with the device. After this, the bracelet will be automatically activated and will be ready to pair with your smartphone via Bluetooth.

How to link Mi Band 2 to your phone?

For the bracelet to work, you will need to install a special Mi Fit application from the company store - Google Play Market for Android smartphones and AppStore for iOS devices. Then you need to turn on Bluetooth on your smartphone. After this, you can open the Mi Fit application.

To connect the bracelet to the phone and any other operations, you will need a Mi account. If available, you must log in to the application. If you don't have an account yet, you can create one directly from the Mi Fit app using your email address. After registering in the Mi network, authorization will occur automatically.

The app will then prompt you to connect to the bracelet. You need to select your device on the pairing screen in the MiFit app. After this, for some time (usually less than a minute), the program will synchronize with the bracelet, and upon completion of this process, Mi Band 2 can be used.

It is not recommended to disable Bluetooth on your smartphone. The memory in the bracelet itself is small (enough for about 12 days of activity), so it needs to constantly upload data to the application.

How to set up Xiaomi Mi Band 2

All Xiaomi Mi Band 2 settings are made from the proprietary Mi Fit companion application.

You can set the following options:

• Bracelet position: left or right hand. When this setting is set correctly, the device will count steps more accurately;
• Information displayed on the bracelet display: time and date, steps, distance traveled, calories burned, pulse, battery charge. If you do not need to show any of this, this option can be disabled;
• Time display format – large clock or small clock with date;
• Turn on the display by raising your hand. If this item is active, the bracelet's screen will light up when you look at it. If disabled, the display will always be on. It is recommended to activate this parameter - this will increase the battery life of the bracelet;
• Using the heart rate monitor in sleep tracking mode. If the parameter is enabled, the bracelet will turn on the alarm at the most appropriate time, but this will increase battery consumption.

In fact, all these settings should be turned on or off based on your personal preferences.

Some bracelet features can be configured in another menu. Among such functions of Mi Band 2 is displaying the name of the caller, SMS text and other notifications. And they are configured directly in the “Notifications” menu.

In this menu, you can select which notifications will be broadcast to the bracelet. Among those available:

• Incoming call. The bracelet will vibrate when there is a call and try to display the contact's name;
• Alarm. We are talking about those applications that are recognized by the Android operating system as alarm clocks (for example, those installed in Google Clock or the stock clock application are recognized, but those configured in Solid Alarm Clock Extreme are not);
• Notifications from third-party applications. The icon of the program that sent the notification is displayed on the screen;
• Inactivity alerts. If the bracelet has not registered activity for too long - well, that is, the user has been sitting for too long without moving - it will vibrate and remind you that it would be a good idea to walk around a little;
• SMS messages. The bracelet will show an icon and try to display text;
• Alarm clock set on the bracelet itself via the Mi Fit application;
• Goal achievement notifications. For example, if the user sets himself the task of walking 10,000 steps per day, the bracelet will vibrate when this number is reached.

You can also set the time at which the bracelet will stop bothering you with notifications.

It is worth remembering that in most cases the bracelet does not correctly display the caller’s name and message text if they are typed in Cyrillic (in Russian). This is due to the fact that the device was not officially supplied to the Russian Federation, and Xiaomi does not have a representative office in our country. Therefore, support for the Cyrillic alphabet was simply not added to the bracelet firmware and application capabilities.

Ways to increase autonomy

Despite the ability of smartwatches to work in offline mode for a long time, many users do not have enough time. In order to increase the autonomy of your device, you can disable some of its functions, for example:

• Synchronizing the bracelet with a smartphone (if it is used, for example, only to view the time, count steps, calories and distance, or to measure heart rate in real time);
• Disable or reduce heart rate measurement;
• Disable notifications from not the most important applications;
• Decrease display brightness;
• Disable screen activation by raising your wrist.

By turning off all these energy-consuming functions, the device will be able to work longer.

How to understand that the bracelet is charged

You can find out about the percentage of charge by the indicators: one LED is on - the bracelet is charged within 30-60%, two are on - 60-99%, three - 100%.

Of course, this kind of data on the charge percentage is quite superficial, and for greater accuracy, the developers have invented a very useful application called Mi
Fit
. The program works ideally with a smart bracelet, tracking the number of steps taken, weight fluctuations, bedtime, its duration and quality. The application perfectly performs all its options on Android devices, but there is also a version for iPhones.

And to find out if the battery is ready for use, just go to the “Profile”

, where your personal information and the number of gadgets connected to your smartphone will be indicated. Next to the required Mi Band 2, find the charging percentage.

And the easiest way: almost always, when connected to a power source, a corresponding icon and the amount of charge at the moment appears on the tracker’s sensor.

Charging Mi Band 5 all subsequent times

Replenishing the charge level is always carried out according to the same scheme. The same power sources are used here and the duration of the procedure is maintained. The only difference from the very first charging of Mi Bend 5 is that you do not need to remove the protective films.

When and how to connect the cable

It is recommended to send Mi Bend 5 for a charge replenishment session only in cases where the user has time to wait until it reaches 100%. Each gadget owner will have to determine the frequency of this process independently. In this case, everything depends on the number of active functions and, as a result, the rate of battery discharge.

You can connect the cable to charge the tracker according to the instructions described above.

How to use the Mi Band 2 bracelet

After the initial setup, the bracelet becomes completely ready for use, so usually instructions in Russian or a user manual for Xiaomi Mi Band 2 are not required. Additional manipulations are necessary only in some cases.

How to reboot Mi Band 2?

There is no usual way to reboot the Mi Band 2. The easiest option is to wait until it is completely discharged. This will be similar to a soft reboot.

To speed up the reboot, you can use an unsafe method. Just put the bracelet capsule in the freezer for a couple of hours. But you should not do this, as this may damage the device.

How to set up a smart alarm clock on Xiaomi Mi Band 2?

In the latest versions of the Mi Fit app, Xiaomi has removed the smart alarm function. Therefore, to activate this feature, you will need to use third-party applications. One of them is Xsmart (download for Android).

• Setting up a smart alarm clock is as follows:
• Set up all necessary alarms in third-party applications (system clock, third-party applications, Mi Fit, etc.); Install Xsmart;
• Open Mi Fit, select Profile, then Devices – and copy the mac address of the bracelet;
• In Xsmart, enter the mac address of the bracelet in the appropriate field and click “Check”;
• Set up alarms in the Xsmart application itself and make sure that the Xsmart item is installed next to each of them.

That's it, smart alarm clocks are set up. In the future, you will only need to turn them on and off, as well as change the time - and all this as needed.

How to reset Mi Band 2 to factory settings?

Without a special flasher (hardware, that is, a separate device) - no way. The bracelet remembers the Mi account to which it is linked, and also stores some information about the user’s last physical activity.

Similar to a "soft reboot", you can do a "soft reset". To do this you will need:

• Open the Mi Fit application, there Profile, on this screen in the “Devices” section find your bracelet;
• Click the “Disable” button located at the very bottom;
• Agree with all application warnings;
• Wait until the bracelet is completely discharged.

After this, it will be in close to factory condition and can be transferred to another person.

An unsafe alternative is a short-term electric shock to the charging contacts of the bracelet. To do this, you will need a piezo generator, which can be removed from a piezo lighter. Its contact must be placed against one of the charging contacts of the bracelet capsule, and the button must be pressed to create a spark.

ATTENTION! This method is not recommended for use as it may damage the Xiaomi Mi Band 2!

How to disconnect Xiaomi Mi Band 2 from your phone?

If you only need to unlink the bracelet from your Mi account, you can use the instructions above. If you need to break the Bluetooth pairing of your smartphone and device, you need to do the following:

• On your smartphone, open the Bluetooth settings (Settings – Bluetooth);
• Find your bracelet among those already paired and click on the icon with the “gear” symbol next to its name;
• Click the “Delete” button in the window that opens.

All. The smartphone will no longer connect to the bracelet. The device itself will begin to vibrate as if the connection is lost.

This method does not delete the Mi account from the bracelet and does not break the binding, so you will not be able to transfer the device to someone.

Tips for extending the life of the bracelet battery

Having learned how to charge Mi Band 5, you should also pay attention to tips that will help make your device more durable. And although the capsule where the battery is installed is very small, problems with it if handled carelessly can be great.

Today's progress has already stepped far forward, and now users do not need to discharge the device immediately after purchase to zero, and then immediately charge it to maximum. Now the task of the owners of such innovations is the opposite - not to bring the charge to 0% .

When sending the device for charging, it still makes sense to wait for the level to reach 100% In this case, this is explained by the ability to use the tracker longer in the future.

Among other things, it is worth remembering that the procedure for connecting the magnetic head to the capsule is correct. These elements do not need to be pressed together or moved when they are already connected. Due to magnetic inserts, the head automatically moves into the correct position, and excessive user movements can only damage the connectors.

And the final, no less important point is charge optimization . This procedure is simple, but every owner of a fitness bracelet should do it. It largely affects the condition of the battery and does not require special skills.

Charge optimization

A procedure such as optimization is carried out at several points. To do this, the user is recommended to perform the following steps:

• increase the automatic heart rate measurement interval;
• reduce screen brightness indoors;
• do not connect the tracker to several applications at the same time;
• use standard dials more often than those made independently.

How to charge Xiaomi Mi Band 2

To charge the fitness bracelet, it is recommended to use the included charger for Xaiomi Mi Band 2, which connects to the USB port of a computer or laptop. It is undesirable to use network units designed for more than 500-700 mA output current. The battery in the bracelet is not designed to be charged with such high currents.

To charge, you need to remove the bracelet capsule from the strap and install it in the appropriate adapter. It is necessary to rotate the capsule so that its charging contacts are in contact with the charging contacts of the adapter.

How long does it take to charge Mi Band 2?

It takes about an hour and a half to charge the fitness bracelet from scratch (if the power source is a computer USB port). The current battery charge level can be viewed in the Mi Fit app.

If you use more powerful power supplies with Xiaomi Mi Band 2, charging time will decrease. But this will increase wear on the battery, which will lead to faster discharge in the future.

Discharges quickly

One of the most common problems with smart devices is poor battery life. If the issue is not a technical malfunction of the device, then you can try to eliminate the cause on your own.

The first step is to calibrate the battery. After arriving from the store, put the bracelet on charge and let it “eat up” to its heart’s content. Do not discharge the device to zero and completely turn off.

Do not use interval heart rate measurement unless necessary. Starting a heart rate measurement every minute will affect battery life.

Choose the optimal brightness level. 3 sticks are enough indoors, 4-5 outdoors. If the bracelet is lying idle in the evening, then there is no point in turning on the night mode.

Avoid using third-party software. Some users complain that Mi band Master affects battery consumption. If you notice a connection between the program and autonomy, switch to the official Mi Fit.

Do not use a custom watch face. Users noticed a connection between a non-standard watchface and accelerated battery consumption

We have collected the results of using the gadget, which were shared by the owners. The numbers are very different.
