Fitness bracelet Mi Band 2 does not charge and does not turn on

Problems with the battery or charging process

Firmware problems

Sometimes, after charging for a long time, the fitness bracelet does not respond to button presses. You can solve this problem: reinstall the firmware or restart your smartphone or bracelet.

In the first case, the procedure is as follows:

• Unlink the device in the Mi Fit app.
• Reinstall Mi Fit.
• Add the bracelet to the application and wait for it to turn on.

Therefore, you need to discharge the battery. To do this quickly, you need:

1. Put the device in the freezer and wait until the Mi Fit app stops finding it.
2. Remove the bracelet, wrap it in cloth and leave in a warm place for 2-3 hours.
3. Connect to the charger for 10-12 hours.

Cleaning contacts

The problem that fitness bracelet users most often encounter is the inability to charge the device. What should you do when your bracelet is not charging? In most cases, you can fix this problem with fairly simple steps. The methods we offer can be used by all users: those who are technically savvy and those who are not.

So, as we wrote earlier, in some cases the problem is on the surface, and in order for the device to work again, you will need to carry out simple manipulations. When figuring out what the problem might be, the very first thing you should pay attention to is mechanical damage. When your bracelet is not charging, inspect the external electrical connections to see if there is an open circuit somewhere. As for the Xiaomi Mi Band, it does not have many such connections.

Perhaps oxidation of the contacts occurred, which was the cause of the breakdown. If you encounter a similar problem, then you need to thoroughly clean the contacts. Usually this method will help eliminate the problem. It is worth noting that the contacts oxidize due to moisture entering the device. Of course, the manufacturer itself claims that the fitness bracelet is waterproof, but if you wet it day after day, take a shower with it, etc., the contacts may oxidize. Upon closer inspection of the device, you can see that the strap and the module are not completely tightly connected. To prevent contact oxidation, it is better not to wet the bracelet, even though the manufacturer allows it.

Hardware problems

The Xiaomi Mi Band 2 bracelet has a fragile screen and therefore, after accidental impacts or liquid getting inside, the device continues to be detected by the Mi Fit application, but does not display an image on the display. This can only be fixed at a repair shop.

If the device has not been dropped and the methods listed do not fix the problem, then it is defective and can be returned to the store.

To summarize, we can say that in most cases the bracelet does not turn on due to a deep battery discharge and buggy firmware, and any user can fix the problem.

The Xiaomi Mi Band 2 bracelet does not turn on immediately after purchase or after use has expired - a common problem with gadgets. Smart watches that will help the user organize a healthy lifestyle and keep track of physical activity have become a fashionable addition to any smartphone. Such a digital device can not only notify you about the number of steps taken and heart rate, but also display notifications from the phone on the screen, informing the owner about all changes without the need to constantly check the device. Problems with the tracker can occur for a number of reasons.

What to do if the Xiaomi Mi Band 3 fitness bracelet does not charge

There are several factors that may contribute to disruption of the charging process:

• using the wrong cable;
• There are different types of USB ports on a computer, for example, connecting the tracker to the USB HUB connector is not recommended, because in this case the device will not charge;
• it is necessary to control the current level, for example, it is not recommended to connect a tracker if the value of this parameter exceeds 700 mA; if this condition is violated, the battery capacity gradually decreases;
• The reason for the charging process failure may be a faulty USB cable connector or a break in the wires under the braid; to check, you need to connect the tracker to another gadget or move the plug to an adjacent socket.

If it is necessary to clean the contacts from dust, use a lint-free cloth soaked in alcohol. Sometimes you may see the battery icon flashing on the screen for a longer period than is acceptable (2.5 hours or more). These watches do not have an automatic shutdown function when the charge increases to the maximum. For this reason, you need to independently monitor the status of the device. When the battery icon continues to flash on the screen, the charging process is not working properly. You need to check the cable for damage.

Today's article is devoted to an issue that interests many owners of the Xiaomi Mi Band fitness bracelet. Judging by the reviews on various forums, many users of this fitness bracelet are faced with a problem when, for some unknown reason, the Xiaomi Mi Band stops working. Based on our personal experience, we decided to offer you several ways to help “revive” your bracelet.

We suggest that you first remember the main characteristics of the Xiaomi Mi Band fitness bracelet, and then move on to ways to solve the problem.

Causes and troubleshooting

After being removed from the box, the device is completely inoperable and most likely the reason for this behavior lies in the discharged battery. There are exceptions when a new fitness tracker is delivered in a faulty condition. How to distinguish a breakdown from a battery that simply does not want to charge? There are several main features:

1. Complete discharge - refusal to charge can occur due to a long absence of connection and as a result of a complete drop in battery charge.
2. The screen is broken - Mi Band 2 bracelets are characterized by a problematic display. A problem with the screen may appear on a brand new gadget; it is recommended to solve it immediately.
3. Malfunction - the tracker has turned off, does not turn on, and the point is not that it is discharged, which means the device is faulty.

How to properly charge the bracelet

According to the manufacturer, the life of one battery of the bracelet should last for a long time. The technical specifications indicate a period of about 1 month. This is assuming that the device is used daily.

However, if the user connects the bracelet to the phone too often and increases the declared load, it may run out 2-5 days earlier. It is worth noting that a full charging cycle to 100 percent takes only 2 hours.

Charging the Xiaomi fitness tracker is carried out according to the following scheme:

1. Release the bracelet capsule from the strap.
2. Place the tracker into the adapter with the side where the contacts are.
3. Carefully secure the structure.
4. Connect the adapter to a power bank, wall outlet, or other power source.
5. Wait for the tracker to start flashing and vibrating. This indicates the start of the charging process.

Note! Owners of the new Xiaomi Mi Band 2 bracelets must wait until the battery is completely discharged before charging for the first time.

If the gadget does not want to charge, you need to find the cause of the breakdown or purchase a new bracelet. The tracker battery cannot be replaced. Let's see what steps you can take to fix the problem.

Cool the bracelet

Everyone knows that it is almost impossible to get to the insides of the Mi bracelet. However, there is one way that allows you to indirectly influence the “filling” of the Xiaomi Mi Band, the effectiveness of which has already been confirmed by many users of the tracker: to get rid of the problem when Mi does not want to replenish the energy charge, it is recommended to place it in the refrigerator for a while. The mechanism of action of this method is such that the cold helps the gadget discharge faster, as a result of which the Mi Band turns off. As a result, a kind of “reset to zero” occurs, that is, a system reboot, as a result of which many problems are solved, including the problem of charging the gadget. Some time after the tracker has been removed from the refrigerator, it automatically turns on, and most often after that it works like new.

How long does the bracelet need to stay in the refrigerator? There are many different options described on the forums, ranging from 2 hours and up to a day. Most likely, the capsule is completely discharged when the Mi Fit program installed on the smartphone no longer detects it.

Checking the integrity of contacts

First of all, you need to check whether the power supply to which you connect the capsule is working. Try plugging in or connecting another device to the power bank, such as a mobile phone. If charging has started, we look for reasons in the bracelet itself, namely in the contacts.

Due to the fact that the owners of the bracelets play sports in them and constantly wear them on their hands, the external elements may oxidize. The reason for this may be increased sweating or external moisture.

Most likely the capsule was not securely fastened in the strap. However, the instructions for the bracelet indicate that it is waterproof. But you cannot swim in it in the pool for more than 30 minutes.

When moisture gets into the body of the Xiaomi bracelet, a chemical reaction occurs. As a result, the contacts oxidize and the device begins to malfunction when connected to the power supply. A characteristic orange coating may even appear on the contacts.

If such a situation occurs, the manufacturer recommends cleaning the contacts yourself. This must be done carefully and carefully. Do not use harsh materials or chemical solutions to remove oxidation from elements.

It is best to take a piece of soft cloth, after moistening it with alcohol. At the end of the procedure, thoroughly dry the contacts and try charging it again. If cleaning does not give the desired results, try the following method.

It is important to know! Damage to the contacts can also cause the bracelet to fall or be hit hard. After this, it may sit down faster and not turn on after successful charging.

Causes of problems at work and their solutions

A device malfunction must have a cause and a solution.

Water penetration into the device

Here are some possible ones:

1. Water penetration . Moisture, repeatedly penetrating into the device, contributes to the oxidation of contacts. You should not wear the bracelet again near sources of water - wash dishes in it, swim in the pool or take a shower if it is not suitable for this. Wiping the contacts can correct the situation, but this may not always work.
2. Discharge . The fitness tracker could simply have discharged to its maximum possible level. This happens when the device is not used for a long time, it is transferred somewhere for a long time, etc. You need to be patient and wait for the highest charging percentage.
3. The charging cable is not included with the device . Using a different charging cable may cause the Xiaomi to malfunction; you should only connect the bracelet to the original charger.
4. Problems with settings . Xiaomi may suddenly stop charging and working due to incorrect settings. The best effect on its contents is cold. It can help restart the device.
5. Manufacturer defect . Unfortunately, a non-working device may actually be defective. The problem may be poor brightness settings, incompatibility of the charger and Xiaomi itself, etc. Poorly produced goods are subject to mandatory return or replacement, since the manufacturer provides a guarantee for its products.

Contact the service center

No one guarantees that cleaning contacts and freezing will lead to the desired results. If the battery of the Mi Band 2 continues to discharge quickly, it must be taken to a service center for diagnostics. A complete list of authorized workshops can be found on the company’s official website www.mi.com/ru. Don't forget to indicate your city in the settings so that the information is displayed correctly.

You don't have to worry that cleaning the contacts and cooling the bracelet will affect the warranty period. Such manipulations will not be reflected in any way on the state of the tracker, unless you are overzealous in your endeavors.

If such problems appear a month after purchase, do not delay contacting the service center. It is quite possible that you received an initially deformed bracelet and it will be replaced under warranty. In addition, professionals have repeatedly encountered such requests and know exactly why the problem occurred and how to fix it.

Important! When contacting the service center, you must take your warranty card and sales receipt with you. If you still have the box, grab that too.

The screen does not work on Mi Band 4

One of the main reasons why the watch does not turn on is considered to be a broken screen. The fourth generation of trackers has an OLED display , which is very susceptible to damage, which distinguishes it from elements made using other technologies.

If the touchscreen (display, touch button) does not work, even if the watch is charged, the reason most likely lies in the state of the screen. To check the validity of the assumption, you just need to try connecting the device to your phone using Mi Fit. When your smartphone detects a new gadget and vibrates the second one, you should be sure that the device itself is working, but the sensor is not responding to it. In this case, it is advisable to take the Bend to the seller and demand a replacement of the product.

A problem with the display may well appear while using the gadget if it is handled incorrectly. To prevent , you should adhere to the following rules:

1. Do not immerse the capsule at great depths for a long time. Users often complain that Mi Bend 4 does not work in the pool. In fact, the tracker is capable of performing its functions, but if water gets inside, the screen fails.
2. Do not drop the device. The fragile watch case can be damaged even if dropped from a minimum height, so you should handle it carefully.
3. Keep the display clean. To ensure the screen is in normal condition, you should stick a film on it or regularly wipe it with a damp and dry cloth to remove dust and other contaminants.

Repairing the display yourself, as a rule, leads to complete failure of the Mi Band 4, so in this situation it is better to contact a service center.

What to do if the bracelet is charged but does not turn on

In the end, I would like to talk about another common problem with the Xiaomi Mi Band 2 bracelet. What should you do if the tracker is charged, but does not want to turn on after being fully charged?

1. Place the device next to your smartphone and leave it in this position overnight. Sometimes batteries go into a so-called “coma” caused by being fully charged. In this case, the tracker must be connected to a power source. As users note, after some time the device comes to life and begins to function as before.
2. Check if the bracelet display is broken. Connect the tracker via the official application to your smartphone. If it vibrates, then everything is fine. The device is ready for use.
3. Try charging the tracker by connecting it to your computer via a USB cable. In some cases, this brings him back to life.

If the bracelet has been charging for a long time, but still does not turn on, try reflashing it. This is done like this:

• Unpair the bracelet from the mobile application.
• Remove Fit Mi from your smartphone.
• Redownload the application.
• Your tracker must independently download the 4pda file with the new firmware and reboot.
• Activate search on your device.

After such actions, the bracelet begins to work like new. You can clearly see all the ways to repair a fitness tracker in a review video on the YouTube platform:

Now you know what to do if the Xiaomi Mi Band 2 bracelet does not charge. Each of the above methods shows its effectiveness, but does not guarantee success, with the exception of contacting a service center. However, in the latter case, you will only be able to benefit from the legal guarantee if you comply with all obligations.

Xiaomi mi band 2 does not charge after being completely discharged - what to do?

It is necessary to check the serviceability and functioning of the battery. This is done by connecting the device to a special charging unit. This can be done by using a USB cable pre-connected to your phone or PC. If the device's battery is good, the charging indicator will automatically display. After it is completely filled, the bracelet is ready for use.

You will need to perform a few simple steps. They will allow you to identify the cause and correct the breakdown. Here's what you need to do:

1. If the charger shows a fully discharged position, you will need to leave it connected to the power source. It is advisable not to turn off the device all night. In the morning it starts working normally.
2. The display has failed. You can easily deal with the problem. You should connect the bracelet to your phone. The gadget will vibrate, which will indicate its readiness for full-fledged work. If positive dynamics do not occur, you will have to send the tracker for repair or replace the battery.
3. The device is faulty. You must act under warranty. The buyer has the right to request a replacement of the first bracelet or a refund of the money paid.

Usually, after a complete discharge, the problem can be resolved. The main condition here is to allow the battery to charge overnight. It is worth contacting repairmen after a thorough check of the charging. Their contacts can be found on the official websites of company representatives.
