Photo from AliExpress.com The Xiaomi Mi Band 2 smart bracelet is used to monitor certain characteristics of the body.
It allows you to measure your pulse, heartbeat, roughly calculate calories burned and make other measurements, and view statistics.
The gadget is quite small in size; therefore, the battery used in it cannot be of significant volume either.
You can charge the Xiaomi Mi Band 2 fitness bracelet from the mains. Despite the small size and capacity of the battery, you can use the watch without charging for quite a long time.
The bottom line is that energy consumption is also relatively low, the device is made with maximum energy efficiency and economy, and allows functions to be turned on and off, depending on need.
Is it possible without a charger?
Most modern electronic devices use a standard device for replenishing energy, the so-called micro-USB. You can connect it to your computer or insert an adapter block and plug it into an outlet.
The limited dimensions of the tracker do not allow the use of just such a device, so the manufacturers resorted to some tricks. The connector is located so that it can only be used when the tracker is disconnected from the strap.

You won't be able to charge your gadget without a charger. You must connect to the tracker and then turn it on to the network or computer. However, such cables are sold freely, so finding an analogue is not difficult.
There are some craftsmen who can charge the device by disconnecting the wires and directly connecting a non-original charger. However, you should not resort to this method if you lack technical skills, as this may lead to damage to the device, which will not be considered a warranty case.

How to determine the current charge level
Before recharging, you need to check what the battery level is. You can do this in two ways:
- Check through the standard menu. You need to press the button located near the screen several times in a row until the desired submenu appears indicating the battery level.
- Go to the Mi Fit app and check the battery level there. The method will only work when the connection and binding to the smartphone have already been completed.
Interesting! You can also use third-party applications from other developers to check, however, the manufacturer does not guarantee accurate information when using such methods.
How long should I charge?
Any electronic device requires a certain amount of time to charge. Most often this is several hours, but it all depends on the size of the battery and the power of the charger.
At first glance, it seems that the question of how long to charge a gadget directly depends on the size of its battery, but not everything is so simple. There are many configurations and models, technical parameters and characteristics.

Charging the Xiaomi Mi Band 2 takes about two hours on average. The battery capacity is small, but the charge is supplied gradually so that the gadget and its battery do not fail, which is why the process takes so long.
For the first time
The initial charging differs little from subsequent ones. Users note that in practice, the initial supply of energy may take a little longer, up to several hours, but such reviews are not always found. It is better to perform initial charging completely, up to 100%.
Attention! Some people advise completely discharging the battery before charging it for the first time. Previously, such methods were justified due to the materials used in the batteries, but now it is just an additional precaution.
All subsequent
All subsequent times, it is also recommended to fully charge the battery. The bottom line is that any battery has a limited lifespan, as well as a limited number of recharge cycles. Modern devices have become much more energy efficient and reliable, but they are still limited.
Therefore, it is better to charge the Xiaomi Mi Band 2 watch, as well as other models, including 1s, when the charge is already low. Partial recharging will only reduce the service life.
It is not recommended to leave the device charging overnight or for any other long period of time, as this can lead to overheating and breakdown.
Pedometer
When walking, it works properly, counts steps and shows the approximate distance traveled. But with some activity without walking, for example, when hammering nails, the number of steps also increases. When you turn on the device for the first time, the program suggests a daily step count based on your data (age, weight and height).
She offered me 8000 steps and I agreed to it. When you reach your daily norm, the tracker will vibrate intensely and show on the screen what looks like a medal. There is also such a feature for motivation as statistics between users. You can see how many people you have bypassed by activity
How to understand that the gadget is charged
You can also check the current charge level in one of two ways, that is, by pressing the control button the required number of times or by looking at the charge in a special application.
The first method seems to be more reliable, as it shows information in real time. The phone may not update the latest information in a timely manner. So, sometimes you will need to completely turn off and turn on the application to update the information.
How long should devices last autonomously?
The battery life of any electronic device depends on its battery capacity and energy efficiency. In the case of Xiaomi Mi Band 2, you can extend the operating time on a single charge to one month.
The tracker's battery is small, but power consumption is also considered low. This allows you to use the watch for such a long period of time.
However, it is worth remembering that the more functions are enabled on the gadget, the faster the battery will drain. If you disconnect the device from the smartphone and use it only autonomously, the period will be maximum. If you enable all functions, connections, add heart rate tracking, sleep monitoring and other features, then in some cases the period is reduced to one week.
Top 5 record holders for operating time without recharging
The Xiaomi Mi Band 2 device is considered one of the most popular fitness trackers on the market. The success of the model was guaranteed due to its good functionality, low cost, and long-term operation without recharging. But this is not the only device that can work for a long time without connecting to the network:
- Xiaomi Mi Band 2 is considered one of the record holders in terms of price/quality ratio; it can work from the network for up to a month, and in some cases more. There have been cases where the device worked offline twice as long.
- Xiaomi Mi Band 3 is a newer model from the same manufacturer. The battery installed in it is approximately the same, but the functionality is a little wider. If you use it in standalone mode, it will work about the same; if you turn on all functions, the charge will run out a little earlier, but not significantly.
- Xiaomi Mijia Hey Plus is an older model, many mistakenly mistook it for Xiaomi Mi Band 4. The battery is slightly larger compared to previous models, but the functionality is also different. When using all functions, on average the charge lasts for 2-3 weeks, which is a pretty good result.
- Huawei Band 3 Pro is a model from one of the competitors. Capable of working for quite a long time, on average about two weeks.
- Huami Amazfit Bip is not considered new, but its battery is quite effective. Can work up to a month.
Important! Considering the fact that fitness bracelets are designed for long-term offline use, battery capacity is considered an important point. But you shouldn’t chase only this parameter. Working without recharging for a week will be more than enough.
Xiaomi Mi Band 2 and phone: a great addition
Two devices such as a mobile phone and a fitness bracelet can be “friends.”
- If suddenly someone calls or receives a message on the phone, the bracelet will immediately tell the owner about this - it will begin to vibrate (the older generation will immediately remember pagers). It also reports notifications on social networks. True, for this I studied the instructions quite a bit, and had to master some settings (then I deleted the program - it was too distracting).
- If your phone is “hidden” somewhere at a distance of closer than 5 m, you can easily unlock it... with a bracelet! The same bluetooth will come in handy.
- The gadget has a built-in storage device that receives statistical information. But it needs to be reset to another device (for example, a phone) at least once a week to a week and a half so that the data does not clog the accessory’s memory.
There is no way to do this without applications, so there must be a “link” to a phone or tablet, smartphone, or computer. This makes it easier and faster to work with your indicators.
Be sure to read this before connecting the tracker to the network
Any battery requires special treatment, as it has limited potential. The device cannot charge forever; sooner or later its efficiency will begin to decline.
Before starting operation, you should pay attention to the following points:
- The initial charge must be carried out completely, up to 100%. This will not only test it, but also provide an additional chance of durability;
- The first time, it is advisable to completely discharge the device until it turns off. This is difficult to do, given the low power consumption; turning on all functions will help, which will also allow you to check them;
- You shouldn’t constantly recharge the gadget, it’s better to bring the charge to 100%. Not everyone agrees with this statement, but most experts advise adhering to this rule to ensure maximum durability;
- During use, it is better to use only the original charger or with the same parameters.
Some of these recommendations are considered precautions only, but following them will increase the chance that the tracker will operate for the maximum amount of time with significant effectiveness.
Disadvantages of the Xiaomi Mi Band 2 version
There is no type of technology without flaws, and this smart device is no exception.
For example, the pulse is not measured automatically, but only after the heart rate monitor is activated (you need to press the button before doing this). There are other gaps:
- Unfortunately, extra steps can be gained by accident - if you vigorously wave your arms throughout the day.
- The gadget is held tightly, it is almost impossible to lose it. But if you want to make such a present for the owner of a thin wrist (or, for example, a child), a non-original belt will come in handy - they have more holes that help fix the device on the hand. The same straps come in other colors and are even available with prints!
- If you are a fan of social networks such as VKontakte or Rugram, you will have to forget about the possibility of incoming notifications for now. They are not recognized by Chinese technology, but Xiaomi is more loyal to other social networks (European and American).
For some, the lack of an analytical base in this bracelet may be disappointing. He does not make forecasts, does not calculate possible options for how many steps still need to be taken, etc. Only a statement of facts. But, as for me, this is enough! Nothing extra!
Main conclusions
Xiaomi Mi Band 2 (Xiaomi Mi Band 2) can be used for a fairly long period of time without additional charging. The manufacturer has optimally configured power consumption, despite the limited capacity of the battery used. But the duration of use will depend not only on the battery, but also on the functions used.
It is important to use the charger correctly. It is best to use what is included in the kit, or choose a cord that fully meets the technical parameters. This will ensure maximum safety and durability.
