In modern smartphones, the option of fast charging is actively used. However, not all devices receive such a useful function. Only owners of mid-range and flagship devices can quickly charge their phones.
But not in the case of Xiaomi. The Chinese company supplies even budget gadgets with Quick Charge technology. It is known for certain that almost all Xiaomi devices of the Redmi line have this option. What can we say about the flagships of the company.
This is a feature that reduces the time until the smartphone's battery is fully charged. It is actively used in cases where there is almost no time for charging. In 15-20 minutes, the device can be fully charged. There are several generations of fast charging technology.
- Quickcharge0. It was announced by Qualcomm in 2013. It allowed you to charge your smartphone in 40% less time than when charging. in the usual way. This technology was equipped with top-end Snapdragon processors at that time.
- Quickcharge0. Was born in 2015. It allows you to charge the device up to 60% in half an hour. This is an excellent result. 2015 flagships got this option along with the latest Snapdragon. To carry out such a fast charge, you need a 9 V block with a power of 2 A.
- Quickcharge0. It is characterized by the presence of intelligent voltage control technology. The processor can choose the most optimal voltage for a certain period of time. In half an hour, you can charge the battery up to 70%.
- Quickcharge0. On the this moment top-end Qualcomm Snapdragon 835 processors have this technology on board. Now the device can be charged from 0 to 50% in just 15 minutes. This is an excellent result. But it is available only to flagships.
So, phones with the fast charging option can be fully charged in just half an hour. But this statement is true for devices with the latest version of this option and the flagship processor on board.
In other cases, it is quite possible to charge the smartphone battery up to 60% in 30 minutes. And this is a good result. If time is sorely lacking, then a little more than half the charge is a big deal.
What devices support the technology?
In the case of Xiaomi, the answer is ambiguous. Often the manufacturer does not declare the presence of such an option in a smartphone, but it is present. However, there is an official list of supported devices. We will rely on it.
- Quickcharge0. This version of the technology is supported by Redmi Note Prime, Redmi 2 Pro, Redmi 2 Prime and Redmi 2 in the regular version. But this list should be supplemented, since almost all devices of the Redmi line have a fast charging mode.
- Quickcharge0. This version is available for all devices of the Mi line. Including Plus, Note and LTE versions. QC 3.0 also has on board the fashion device Mi Mix. And the "most resistant" Mi Max has a newer version at its disposal.
- Quickcharge0. The third version is supported by gadgets such as Mi Mix 2, Mi6, Mi5, Mi 5S Plus, Mi Note 2 and the standard version of Mi Mix. The list is not particularly long, but it lists the most technically advanced gadgets.
- Quickcharge0. And here there is no list at all. So far, only one smartphone can be recorded in it. The latest flagship is Mi 7. It is he who is equipped with a Qualcomm Snapdragon 835 processor and fast charging technology of the corresponding version.
If the device you need is not on the list, then do not be discouraged. It's possible that the smartphone supports the technology, but is simply not placed on this list. It is easy to check: you can connect a charger for 9V and 2A. If an icon appears depicting a lightning bolt in a circle, then there is definitely a QC.
As for the popular Redmi 4X, the manufacturer did not provide up-to-date information about it. But many users report that the fast charging mode is present. Exactly the same story with Redmi 5A, Redmi 3, Redmi Pro, Mi A1, Redmi 4 and Redmi 4A. Support is available. But not announced.
How to enable fast charging on Xiaomi?
For this, certain conditions must be met. In any case, enabling fast charging on a Xiaomi smartphone is very easy. And it doesn't matter what version of the device: Redmi, Mi or Pocophone. So, what do you need to enable Quick Charge mode?
- Charger. It is required to use only the original Xiaomi charger with a voltage of 9 V and a power of 2 A. If this is not the case, then nothing will come of it. Other charging does not support this technology. And Xiaomi has its own characteristics.
- Official firmware. This option does not work on custom firmware. Therefore, it is mandatory to have the official MIUI from Xiaomi. Even "pure Android" won't work. Although it works several times faster.
- Installed updates. The operating system of the smartphone must be updated to latest version. it required condition. Phones with older firmware may not support Quick Charge.
If all requirements are met, then you just need to connect the original charger to the device. An icon depicting a lightning bolt in a circle should appear in the status bar. This is the symbol for fast charging.
Conclusion
Quickly charge your smartphone modern realities very simple. The main thing is that he has on board a processor with support for Quick Charge mode. Charging time can be reduced by 60%. And this is not the limit.
New flagships will charge even faster. And over time this technology will migrate to cheaper smartphones. In the future, Qualcomm plans to develop a new generation of Quick Charge. And it will be a real sensation.
Until recently, fast charging has been an exclusive advantage of smartphones based on Android OS. Apple Corporation albeit very late, but still recently released a new series of devices that also support this technology.
Despite the fact that Quick Charge has been implemented in many smartphones based on Qualcomm processors for quite a long time, many users who have picked up gadgets with support for this technology for the first time have many questions about the principle of its operation and the effect on the battery. Our article will help you understand this subtle issue that interests many Xiaomi smartphone owners.
Quick Charge is a technology that allows you to charge the battery for a much shorter period of time compared to conventional charging and with absolutely no harm to it.
The bottom line is that the charging unit supplies current with a voltage significantly higher than the standard 5V. So, Xiaomi smartphones are equipped with blocks with an output voltage of 12V. That is, the usual cable of the complete charger is simply connected to the smartphone, but the battery fills up literally before our eyes. And, accordingly, when you connect a third-party charger, your Xiaomi charges at the usual speed.
The emergence of this technology was the result of an increase in the capacity of batteries modern devices while increasing their performance and increasing charge consumption. Another important factor of influence is the pace of human life, at which charging a smartphone for more than 3 hours has become simply an unaffordable luxury.
Modern mobile devices are powered by lithium-ion and lithium-polymer batteries, which are based on the thinnest metal electrodes, the space between which is filled with liquid or solid electrolyte. When you connect the charger to the phone, electrochemical processes of charge accumulation begin to flow in the battery. Accordingly, at the moment of disconnection, the battery switches to the mode of returning the accumulated charge to the consumer, that is, to the phone itself. The bottom line is that these processes have their own speed and cannot be performed faster without harming the battery cell.
If it was previously believed that the batteries of mobile devices can safely accept a current of 11W (5V * 2A), allowing you to accumulate about 2000 mAh in the battery for an hour, then thanks to modern ones, other results have been achieved. It turned out that lithium-based batteries are able, without the risk of degradation, to perceive the current strength corresponding to their capacity. That is, with a capacity of 3000 mAh, you can supply a current of 3 amperes (A), which is equal to 3000 milliamps (mA), and at 5V voltage - 15W. But increasing the current strength requires the use of other conductors and is fraught with additional heating of the battery. Therefore, it was decided to increase the current power by increasing the voltage while maintaining the current strength.
The first manufacturer to introduce the fast charging function was Qualcomm, which began to apply the developed technology in the production of Snapdragon mobile processors.
Which Xiaomi smartphones support the technology?
There are several versions of Qualcomm's Quick Charge technology. Accordingly, all Xiaomi devices, depending on the supported version of fast charging, are divided into the following categories:
QC1.0:
- Redmi Note Prime;
- Redmi 2 Pro;
- Redmi 2 Prime;
- Redmi 2.
QC2.0:
- Mi Mix;
- Mi 4c;
- Mi 4i;
- Mi 4;
- Mi 4 LTE;
- Mi 5 Plus;
- Mi 5;
- Mi note;
- Mi 3.
QC3.0:
- Mi Mix 2;
- Mi 6;
- Mi Mix;
- Mi 5s Plus;
- Mi note 2.
In some forums, users report that Xiaomi devices that are not included in the list of those that support fast charging can formally be charged from specialized units that produce voltages of more than 5V. However, this does not mean that the phone will actually charge faster.
Results on the example of Redmi Note 3S
As an example, consider the charge graphs of the Xiaomi Redmi Note 3S smartphone with a 4100 mAh battery, which does not support Quick Charge. In the course of the study, the smartphone was charged using a complete unit, as well as QC 2.0 and QC 3.0.
The following results are obtained:
For convenience, the data obtained are summarized in the table:
According to the charge graphs, the smartphone has formal support for fast charging mode, since during connection it requests a voltage of 9V from QC 2.0 and about 6.5V from QC 3.0. However, the impact on charging speed is negligible. This can be explained by software limitations - the battery charge controller does not pass current power above 11W.
How is the charging process?
Fast charging does not require activation or inclusion. It's just a technology that can be supported by the device.
If your Xiaomi is included in the list of devices listed above, it means that Quick Charge is supported out of the box and along with the phone you also purchased a specialized charger.
Attention! Xiaomi chargers supporting Quick Charge of any generation are certified by Qualcomm. However, there are manufacturers who have chosen their way of the samurai. They developed their own fast charging technology, but with their own battery controllers and chargers. Accordingly, their performance is radically different.
Using a charger from another manufacturer to charge your Xiaomi is highly discouraged - at least you won’t be able to quickly charge your smartphone. In the worst case, you will have to contact the service to replace the burned-out battery controller, or even the nearest electronics store to replace the damaged smartphone. It's all about lithium batteries, which do not tolerate neglect and currents that do not correspond to passport ones.
At the moment the fast charging unit is connected to the smartphone, the latter starts to "communicate" with the charging unit, requesting the necessary voltage depending on the current amount of charge. So, in the range from 0 to 80%, the maximum voltage of the charging current is requested - about 12V. This allows you to charge the battery up to 80% in just 30-35 minutes. After reaching the limit, the charging unit switches to the normal current supply mode with a voltage of 5V. This is necessary to ensure the normal functioning of the phone's battery and its premature failure.
Thus, from 0 to 80% the phone charges in 35 minutes, and from 80 to 100% - in another, on average, in 30 minutes. This allows you to restore the phone's battery at a crucial moment when you need to urgently run on business, and your electronic friend complains about a low empty battery and threatens to leave his owner without communication right in the middle of the working day.
After the first appeared mobile phone, the main problem for developers was the question of its operating time in different modes. If at the dawn of this industry such a question did not become an edge, then with the advent of more "smart" devices, it became important to extend the phone's operating time for the maximum possible period. Nowadays, Xiaomi devices are slowly conquering the world, and in the article we will talk about their proper charging using the example of one of the most successful smartphones - Xiaomi Redmi 3S. How to charge at the beginning of use specifically this device and all the others, we will try to explain in as much detail as possible.
Reasons for fast discharge
As it used to be, so now the phones were discharged quickly and there is no getting away from this. The only paradox is that today's phones are hundreds of times more productive than their ancestors. Yes, the batteries have become better, their capacity has increased three, four, or even more times, but the charge costs have also increased. Cause in large numbers operations performed by them and whatever you do, the device will not be able to work for more than 6-7 hours at full load. But there is one important point which we must talk about.
Incorrect use of the battery causes it to hold a charge less and discharge faster. Solving this problem can be quite simple. The Xiaomi Redmi 3S considered in the article, when used at full power, will last about four hours and this is normal, it is important for us to figure out how not to lose this shape over time. You probably noticed that after six months or a year, the phone is no longer capable of its previous continuous operation. In order to avoid such an unpleasant outcome, we will figure out how to charge the Xiaomi Redmi 3S battery correctly.
We warn you in advance against using non-original chargers. In addition to the fact that they can cause the charge controller in the phone to malfunction, break it down, but there are also known cases of fire.
Proper battery bleeding
An old and long-proven method tells us that after buying a device, it is necessary to fully charge and discharge the device three times in order to “harden” the battery, using all its power. We offer more modern version such pumping, because the batteries are now different than they were before. Immediately after purchasing Xiaomi Redmi 3S, you need to put it on a long charge. Farther:
- after the purchased phone has been charging for at least 12 hours, unplug the cable and turn on the switched off device;
- put it on charge again, which should last about 1 hour;
- remove from the charger and turn off the phone for a few minutes;
- now already turned off, charge it for about an hour;
- after the done manipulations, you can turn on the phone and use it.
Now your Xiaomi Redmi 3S should be ready for a long and high-quality work that does not “kill” the shutter speed and battery power.
Fast charging and its consequences
Many people claim that fast charging your phone ruins its battery, but this is not true. Entire laboratories work on this technology with scientists conducting thousands of tests, during which they try to give us something more. There's already talk in inventor circles that we won't have long to wait for phones to charge instantly. It is unlikely that such a jump in this matter can be called one that is aimed at the deliberate "killing" of batteries. Xiaomi Redmi 3S does not have a fast charging function, and even with a special cable, the difference in the charging process with a regular cable is not significant. So if you wanted to try this method with your phone, you can not spend money on it.
Is Power Bank Harmful
As for the conversations around the Xiaomi Power Bank, we can safely say that such a device will not cause any harm to your phone. In general, it is worth noting that current batteries have a built-in controller that does not allow damage to the battery by charging it, since this very controller monitors the current supply, its voltage and other parameters.
conclusions
The main problem of rapid loss of charge or obsolescence of the battery is its improper use, and in order to try to prevent these moments, it is necessary to carry out a series of procedures for the first charge of the battery after buying the phone. You don't even need to know how to properly charge your device, as it's better to take care of how to use it properly. Disable as needed Mobile Internet, Wi-Fi, do not install animated wallpapers, constantly clean the RAM, turn on the automatic brightness mode, do not unlock the phone when not needed. In short, treat the device with care and it, like its battery, will last you a very long time.
Now visitors to RuleSmart often ask the question of such a plan, they say, how to enable fast charging on a smartphone. Of course, there are those who want to turn it off. In both cases, all this looks quite interesting, if not comical.
First, let's figure out what's what. Fast charging technology allows you to increase the speed of filling the battery capacity, often by a multiple. This technology is relevant, for the most part, for batteries with a capacity of over 3000 mAh. Everything below does not make sense, you can use 1A there.
How to enable fast charging
If your smartphone does not support this technology, then nothing. Well, you cannot enable software that is not supported by hardware. But do not worry, you can take a more powerful power supply, if 1A is supplied with the kit, then take 2 A and the charging time will be reduced by about half. But do not forget that this will not add “life” to the battery, but will shorten its operational life.
Now let's move on to the technology itself. In fact, the "chip" is called Quick Charge - this is the development of Qualcomm, which became the first among the fast charging standards. The technology is based on increasing the current strength. Nothing new, just minor software improvements with a minimum of hardware movement.
- Quick Charge 2.0: up to 50% battery charge in approximately 30 minutes
- Quick Charge 3.0: battery charges up to 80% in about 35 minutes
- Quick Charge 4.0: 20% more efficient than the previous version and almost does not heat up the case.
All the "shamanism" is concentrated in the power supply itself, while the control is at the mercy of the processor (from Qualcomm, of course). Significant hardware work was carried out here.
The main function of Quick Charge is to recognize the current state of the battery and adjust the power supply correctly. In this case, charging from 0 to 60% will be much faster than charging from 60 to 100%. In this scenario, from 0 to 50% of the battery will “fill up” in 30 minutes, and thoughtful power regulation will not allow high voltage and current to harm the battery.
Which smartphones support fast charging?
Such smartphones include, for example, Xiaomi Mi6, Xiaomi Mi Max, HTC 10, Meizu MX6, LG G6, Moto X Force, Galaxy S8 and many others. In any case, the Qualcomm website provides an exhaustive list.
How to turn off fast charging
Not every device can boast the ability to programmatically disable fast charging. However, if there is such an opportunity, then just go to the Settings-Battery (Power or Battery) section, there you can configure the whole thing. In addition, you can simply start using a regular adapter with 1A, which will charge your gadget for a long time, but will not reduce the battery life as much. By the way, fast charging also leads to excessive heating, which is not good.
Smartphones have become part of Everyday life modern man. To be in touch, you need to take care of the battery of the device. However, there is not always an extra 3-4 hours to fully charge the device. To solve this problem, the developers have created a fast charging function, which we will explain in more detail.
What is fast charging? This is any charger that feeds the smartphone more than 10 watts.
What charger do you have? Let's check!
Take your power supply and pay attention to the parameters A (amps) and B (volts);
multiply the indicated values.
If the result is more than 10, then your unit supports fast charging.
It is important to remember that there different types fast chargers and blocks, which may not match the model of your smartphone. Because for Xiaomi phones we recommend using fast charging from Qualcomm.
But sometimes it's not only the recharge unit, but also the smartphone itself - not all models support the implementation of fast charging. Xiaomi has a fast charging function in almost all devices of the Mi line.
Using the icon in the status bar (if your phone has a proprietary MIUI shell), you can find out how your smartphone is charging:
lightning - the battery is charged in the usual way;
Lightning in a mug - fast charging.
While using fast charging, the smartphone and the power supply transmit information to each other using a special protocol. Why is he good?
· safety;
* If the smartphone's temperature rises too much during fast charging, the unit will reduce power.
Smart monitoring of charging data.
The unit changes the voltage depending on the level of battery charge. It is safe and harmless to smartphone battery.
If you use conventional charging, the battery will function well after 1000 charge cycles, using fast charging - about 800 cycles.
