How to speed up the charging process of your smartphone. How to properly charge devices on the Android platform

To increase time battery life gadgets on Android, manufacturers are forced to increase battery capacity. But at the same time the charging time Android devices becomes longer. And the question is becoming more and more urgent - how to enable fast charging and check whether it supports this function your device?

What is Quick Charge?

A phone that goes off at the wrong time is already the reason for a bad mood for almost everyone modern man. There are several ways to “reanimate” a phone. This is an adapter for a battery, a powerbank, or an adapter with a function Quick Charge. Let's look at Quick Charge in more detail.

Quick Charge is modern development from Qualcomm, which pioneered fast charging standards. This technology works by increasing the current supplied to the battery from the power supply.

There are already three Quick Charge updates:

1. Quick Charge 2.0. The battery is charged to 50% in approximately 30 minutes
2. Quick Charge 3.0. The battery charges to 80% in about 35 minutes
3. Quick Charge 4.0. According to research, it is more effective previous version by 20% and almost does not heat the case. The current voltage is selected individually for each gadget and charging period

Most of the technology is in the power supply, and the processor is responsible for controlling current and voltage.

Fast charging function

The main function of Quick Charge is to recognize the current state of the battery and properly regulate the power supply of the gadget. Thanks to this, charging from 0 to 60% will be much faster than from 60 to 100%. This makes it possible to charge the device from 0 to 50% in 30 minutes. Proper power regulation will not allow high voltage and current will harm the battery.

How to enable fast charging

When purchasing a new smartphone, many users begin to understand it and wonder how to enable fast charging. In order to quickly charge the device, you need a smartphone itself that supports this function, powerful block power supply, which also supports accelerated charging and a USB cable. No additional measures are needed. The function is activated automatically during charging, provided that the device supports Quick Charge.

On at the moment There are already quite a few smartphones that support this function. Namely: Xiaomi Mi6, Xiaomi Mi Max, HTC 10, Meizu MX6, LG G6, Moto X Force, Galaxy S8 and so on. More full list can be viewed on the Qualcomm website.

How to disable fast charging

Quick Charge is a great feature that allows you to charge your phone many times faster. But there is one negative point in it, which poses a significant threat. This is heating of the body and insides of the gadget, which can cause permanent damage.

Not all devices have the option to disable fast charging. Some firmwares have it. To check for this feature, go to the battery settings menu. If you cannot disable the function programmatically, then there are two options for resolving the issue:

1. change
2. buy a less powerful one charger

If you enable fast charging, what's the harm?

It has long been no secret that slower charging is more gentle on the battery than fast charging. A side effect of fast charging is that the case heats up. High temperature almost always has a bad effect on any electronic devices. And yet, at the moment there is no absolute evidence that frequent use of fast charging Quick Charge negatively affects the performance of the battery and the device as a whole.

The average lifespan of a smartphone is about 1.5-2 years. During this time, the user will not have time to exhaust all battery resources. The wear and tear will be the same as using a conventional charger.

If you have any questions regarding Quick Charge, write in the comments.

Answers to questions

Fast charging does not work. What could be the reason?

Make sure your device and power adapter support Quick function Charge. Also, the malfunction of the function is affected by a possible breakdown of the smartphone, adapter or USB cable.

Perhaps every person has encountered an unpleasant situation when, before leaving home for an important meeting, they suddenly discovered that the charge in the mobile phone battery was almost exhausted. Moreover, there was sorely not enough time to charge it. It is not surprising that the question of how to charge a phone very quickly worries every second owner. mobile device. Fortunately, there is still an effective answer to this. This is exactly what we will talk about today. It’s worth noting right away that you shouldn’t expect any miracles.

Change the power source

A charger is always included with every mobile phone. Its task is extremely simple: convert the alternating mains voltage of 220 Volts into direct voltage and reduce it to a certain value determined by the features of the device model used. If you carefully study the data provided on the charging case, you can see Input/Output there. For an owner interested in how to charge a phone very quickly, the data presented in the second line is most valuable. For example, it could be "5V/300mA". What does this mean? The first number indicates the output voltage. In the vast majority of chargers from modern mobile phones, it is always equal to five volts. This is done for compatibility with the computer standard which provides exactly the same 5 V.

Now everyone knows how to charge a phone without charging - just connect it to the appropriate port system unit or laptop. But the second number is the charger’s output to the phone per unit of time. Depending on the charger model, given value can range from 300 mA to 1.2 A. Those who do not want to read further about how to charge their phone faster can be advised to simply replace the charger with one in which the current is higher than in the “native” one.

Amps and battery

One of the characteristics of any battery is that it indicates the amount of accumulated For example, a battery with a capacity of 1 Amp after complete discharge will be able to recover to its original state in 1 hour, provided that the charger supplies it with a current of 1 A. Accordingly, a charger that produces 300 mA will charge such a battery in about 3 hours. IN in this case Capacitance is usually specified in watts rather than milliamps. You can find out the battery current simple division power per voltage. It would seem that it is enough to replace low-current charging with a more powerful one - and you don’t have to think about how to charge your phone faster. However, this does not give results in all cases.

Features of charging replacement

Sometimes from people who at one time studied how to quickly charge an Android (phone), you can hear that if you change the “native” charger with a low current to a more powerful model, then you can disable your mobile phone. This statement is only partly true. In modern mobile devices communication, a special microcontroller is used to regulate the amount of current supplied to the battery. That is, if the “native” charger produces 300 mA, and it is replaced with a model with 1 A, then you may encounter a situation where the controller will limit the incoming current to 300 mA. The difference in this case is dissipated as heat. From all of the above, the conclusion follows: if after the phone began to get very hot, then from this simple way need to refuse.

Use the updated version

Those who are interested in how to quickly charge a phone should know that there are two universal serial bus standards in the world - USB 2.0 and 3.0 (older versions are practically no longer found). One difference is the amount of current that can be transferred through the corresponding port. In the second version, its value reaches 500 mA. But in the newer revision 3.0, not only the data exchange speeds were changed, but also the power circuit, making it possible to transmit as much as 900 mA through such a USB port. Thus, one of the effective and safe options How to charge a phone without charging is to connect the mobile phone to a computer USB 3.0 connector and watch the process of filling the battery. Since the port itself in the standards is externally the same, to determine which is which, it is recommended to use the instructions for motherboard or laptop. Some manufacturers highlight the newer, third version of the nest in color, but this is rather an exception. In principle, this method similar to replacing the charger with a more powerful one.

Take advantage of the software feature

For those who are looking for effective way To find out how to charge your phone faster, we can advise you to look through the instructions for the computer board. In many modern solutions Manufacturers provide the possibility of accelerated charging battery mobile phone For example, Asus offers proprietary technology proudly called AiCharger. Although there is nothing revolutionary about it, it still works. You just need to install the application of the same name and connect your phone to the port. In this case, the current passing through the connector increases to 1-1.2 A. A similar mechanism is offered by the Gigabyte company. On boards from this manufacturer, the function of increasing the current per port is called On/Off Charge (sometimes 3x USB power boost). True, the phone will have to be connected to certain connectors, which are indicated in the instructions. These features are still inferior in terms of ease of use to simply replacing the charger.

Buy a special USB cable

Everyone knows what a standard Universal Serial Bus wire looks like. However, owners of external hard drives and floppy drives are familiar with modified USB cords made in the shape of the letter Y. On one side of such a wire there is a plug connected to the device (phone, CD drive), and on the other there are two connectors connected to free USB connectors on the computer. This is a kind of “tee”. When using it, the output current almost doubles. That is, for USB 3.0 you can theoretically get 1800 mA. The disadvantage of this charging method is that not everyone has a Y-wire on hand.

Turn off your device

There is a completely effective solution to charge your phone faster. Many mobile phone owners do not charge their electronic assistant quite correctly. Speed ​​up this process possible by simple shutdown power supply to the phone while charging the battery. Sometimes this gives an almost twofold reduction in the time spent.

Long enough mobile phones wasn't needed accelerated charging. Why, if the device was connected to the charger only once every three to four days? But with the advent of smartphones, everything changed. These devices have increased energy consumption. As a result, we have become accustomed to the fact that in most cases they need to be charged every night. But what if you forgot to connect your gadget to the charger in the evening, and you have to go to work in the morning? It is in such situations that it saves fast charging. While you brush your teeth, make your bed and get ready for work, the battery will be recharged by 50% or even more. Let's talk about this technology in a little more detail.

Any battery operates on the principle of an electromechanical process. It runs in both directions - the battery can receive energy, storing it, or release it. Over the years, engineers have tried different chemical current sources. Previously used nickel And lead, now all batteries for mobile phones are based on lithium. They can be lithium-ion or lithium-polymer - it doesn't matter at all, since fast charging technology works with both types of batteries. The main advantage of lithium is that it does not have a “memory effect”. As a result, you don’t have to wait for the moment when your smartphone is completely discharged. Yes, and you don’t have to charge it to 100%. If not for this fact, fast charging would be useless. As for the disadvantages lithium batteries, then they consist in a gradual loss of capacity and fire hazard.

IN modern smartphones put batteries with a capacity from 2000 to 7000 mAh. The nominal battery voltage is most often 3.5-3.7 V. When the battery is fully charged, the voltage can be increased to 4.2 V, which allows increasing the performance of the processor and some other components. As for charging the battery itself, it used to be very simple - the current was supplied with a strictly defined power until the charge level reached approximately 90%. Then the power was gradually reduced so as not to “overcharge” the battery; this was done by a special controller. And so on until reaching 100 percent charge. As a result, the charging time was 2-2.5 hours, depending on the battery capacity.

How does fast charging work?

The company was the first to try to change something Qualcomm. In 2012, it introduced the first version of the technology Quick Charge. According to the idea of ​​the manufacturer of mobile chipsets, at the first stage the charger should produce a current of the maximum possible power. And when the battery controller realized that the charge level had reached a certain level, the power was reduced.

How does fast charging differ from regular charging? Let's look at this with an example. Let's take the most common phone charger (pictured above). On its body we will see the inscription: “Output 5V/1A”. This means that the device outputs a maximum current of 5 volts and 1 ampere. Output power such a charge is approximately 5 watts. Technology Quick Charge 1.0 changed little. Smartphones that support it have learned to accept electricity with a current of 2 A. All other parameters of the charger remain the same. Assuming the same battery capacity fully charged carried out 30% faster.

The second version of the technology from Qualcomm turned out to be much more interesting. It consists in an even closer interaction between the battery controller and the charger. From now on, the current could reach 3 A. Also, now the voltage changed during charging - at first it was 12 V, then decreased to 9 V, and finally dropped to the standard 5 V. Compared to using a traditional charger, the process was accelerated by 60 %! The disadvantage of this technology is the high cost of the charger, because it has a special chip built into it. However, most consumers do not care about this, because most often the charger is included with the smartphone, and the need to buy a new one arises extremely rarely.

In September 2016, Qualcomm introduced the technology Quick Charge 3.0. The chargers and battery controllers that have it are even smarter. Now the optimal voltage is selected individually for specific device and battery charge level. The voltage now varies from 3.6 to 20 V. The change step is only 200 mV. As a result, the third version of the technology turned out to be 38% more efficient than the second. Snapdragon 430, 617, 618, 620 and 820 processors received Quick Charge support.

Versatility

Not all smartphones are equipped with a Qualcomm processor. Fortunately, in different devices on Android based There are also other fast charging technologies. Almost all of them work according to the principles described above. In this case, the phone can be connected to a high-performance charger from another manufacturer - nothing will happen to it. In some cases, its power controller will allow you to charge your smartphone at an accelerated pace. In other cases, recharging will proceed in the traditional mode - with a current of 1 or 2 A. In any case, the charger will not harm the device.

However, it is better to use the charger that came in the kit. There have been cases all over the world when the battery caught fire for some reason. This was caused by a Chinese charger and a low-quality USB cable.

Special mention should be made of products under the brand OPPO. It uses a unique technology VOOC Flash Charging. The batteries of smartphones equipped with it have eight contacts. Electricity enters the battery with a current of 4.5 A and a voltage of 5 V. The battery consists of several cells and the current is evenly distributed between them. As a result, recharging occurs very quickly. The manufacturer also claims that its technology is more gentle on the battery without reducing its service life.

Is fast charging harmful to your phone?

What scares some people the most is that fast charging of a smartphone is carried out using increased current. It seems to them that the battery does not tolerate such treatment. Allegedly, in just a year it will have to be changed. Indeed, the first fast charging technologies had an unpleasant feature. The working capacity of the battery quickly decreases if the smartphone is used too actively, charging it once or even twice a day. However, a lot of water has passed under the bridge since 2012, and now everything has changed.

Modern technologies allow the power controller to accept electricity in the amount required by the battery at a particular second. Current and voltage never exceed threshold values. All this is confirmed by numerous experiments from independent experts. They showed that the battery capacity drops at the same rate as when using a conventional charger. Therefore, you can not be afraid to use fast charging - it will only make your life easier.

How to disable fast charging?

If you are still afraid of fast charging, then your further actions depend on how fresh your smartphone is. The fact is that on modern devices, support for this technology is implemented at the controller and firmware level. It is most often impossible to disable fast charging in such gadgets. The only way out is to purchase another charger that does not support fast charging technology.

Well, on smartphones from 2012-2014 you can still disable this function. This is done in " Settings", in the section " Battery" On Samsung devices, you may need to visit pre-installed application Smart Manager.

AC adapters with fast charging for Samsung and Apple

The South Korean company Samsung equips many of its smartphones with support for proprietary fast charging technology. The corresponding adapter is supplied with the device. However, some users lose this little accessory, while others require additional “charging”, for example, for use at work. In short, it would be surprising if the South Korean giant did not sell power adapters separately.

IN Russian stores Products with support for fast charging from Samsung cost from 1200 to 1500 rubles - this is quite an adequate price. Adapters are available with or without cable. What also differs is what kind of connector the wire is equipped with - there have been options with it for quite a long time, since flagships have just such a socket. Largest quantity of the “charges” being carried out are colored in white. But if you try, you can also find a black version on sale, which is much less common.

AC adapters supporting fast charging on AliExpress

The most famous Chinese online store offers many accessories for smartphones. Including in its vastness you can find power adapters with support for fast charging. For example, it is delivered directly from a warehouse in Russia network charging Fonken, with miniature dimensions. The device is primarily intended for smartphones and tablets that support Qualcomm Quick Charge 3.0 technology. The cost of the accessory is approximately 500 rubles. Not bad, especially considering that it comes with a meter-long USB cable with a high-quality braid.

The adapter from Tiegem also supports the same fast charging technology. This device is already priced at 800 rubles, but it is much more versatile. The fact is that you can connect up to two gadgets to this charger - this is exactly the number of USB ports built here. The current is 2.4 A and the power is 30 W. This charger is ideal for products from Huawei and other large companies.

Of course, this is not a complete list of power adapters sold through AliExpress. Here you can find the most accessories different forms and colors. There are even solutions with five connectors! Also, for some time now, the Chinese online store allows you to buy original products from the same Samsung - South Korean adapters are now also included in the AliExpress assortment.

Smartphone users, regardless of “religion,” i.e., what device (iOs or Android) you have in your hands, know that you shouldn’t leave home with an empty battery. What to do when there are only a few minutes left before you go to work or run errands. In today's article we will find the answer to a pressing question: how to quickly charge your phone so that it works for at least 3-4 hours. Let us warn you right away that we do not live in a fairy tale and it will not be possible to fill the battery to 100% in 30 seconds; such technologies are at the development stage.

Manufacturers Android gadgets have repeatedly announced the so-called “Fast Charge” function. Samsung, Motorola, HTC tried to solve the problem of quickly charging a smartphone without killing the device’s battery, some of them succeeded, but for the general mass it remained at the level of marketing illusions.

For example, Samsung Galaxy S5 can be charged up to 30% within 15 minutes from zero percent, a good indicator, but still not the ultimate dream of many users. Unfortunately, Apple company does not announce such a function in its devices, but it is there! Fast charging of the legendary iPhone has become especially relevant with the release of the energy-intensive iPhone 6, 6 Plus, 7, 7 Plus onto the market, let alone the 8 iPhone model, which is said to have a capacity of 3000 mAh.

Since the vast majority of devices do not have a built-in emergency charging function, below we will look at how to quickly charge almost any phone in 10 minutes, give examples and even attached video instructions.

We use a powerful power source

The first thing that comes to mind is to take a more powerful power adapter, the decision is correct, but you need to know some life hacks.

Not many people know that the iPad comes with a powerful charger that produces 2.1 amperes; with its help you can charge not only iOS devices, but also Android smartphones, be it Galaxy series or any other. You just have to temporarily replace the standard iPad cord with a lighting connector, with micro USB Fortunately, the adapter has a USB connector.

If you don’t have such a power source, no problem; you can purchase a power supply that produces a minimum of 2.1 amperes at any store like Svyaznoy or Euroset. There are a lot of similar devices, the main thing is not to buy cheap ones Chinese fakes. They only work for a couple of months and the saddest thing is that they do not produce the declared current, and there are also voltage surges.

To understand how long it takes to fill a phone battery with energy, you need to be able to correctly calculate the charging time. It sounds more complicated than it actually is.

The principle of the charger is quite simple: when the charger is connected to a network with a voltage of 220 Volts, the voltage drops to 5 V and is converted into D.C.. To calculate how long it will take to charge a smartphone battery, it is enough to know the capacity in mAh and the output current of the unit. Let's take, for example, the common output values ​​of 5 V and 1000 mA, this means that with a battery capacity of 1000 mAh, it will take about 1 hour to fill the battery to 100%. For standard smartphone, charging time will be approximately 2-3 hours, provided that an original charger with a calibrated output voltage is used.

Software tools

Specialized programs will help not only if there is an urgent need to charge your smartphone (iPhone or Samsung, it doesn’t matter, there are similar tools for all platforms), but also in cases when the battery on the phone quickly and unexpectedly discharges. Let's figure out how to save battery power for each platform separately.

Android platform

How can you save battery power using the DU Battery Saver and avast battery saver applications for the Android platform?

The DU Battery Saver app can manage power profile settings. Modern interface and many useful options, will help you save a lot of cell phone energy. The operating time increases by 10-30% if you strictly follow all the tips and pop-up hints.

Avast battery saver does not lag behind in functionality, Samsung owners You just have to install it to extend the life of the device by a few hours. The application will help optimize the power supply schemes of the Android OS.

iOS platform

The iPhone Mobile Doctor pro application will help you figure out which application or interface is eating up your device’s battery so much. An excellent informative program for those who like to control their device completely.

Other ways to recharge your battery

There are a lot of banal and at the same time unusual ways filling the battery of the device with energy. Let's look at some of them.

We use a computer or laptop

How can you charge your phone without using a charger? It's simple, connect the cord to the port computer usb. Some laptop and PC models have a special connector with increased output voltage, up to 2.1 amperes. This will answer the question of many users smart gadgets How to quickly charge any phone from a computer via USB. The charging time in this case will be no more than 2 hours, for iOS and Android smartphones.

We charge the battery directly

Connecting any charger directly to the battery will help restore the battery’s operation, even if the power controller on your iPhone or Samsung has burned out. To do this, you need to connect the battery contacts to the so-called “frog”.

How to charge a phone with a frog - at the top of the video you can see how, using the antennae of the charger, the phone's battery is charged directly, without the use of additional harnesses and controllers.

So it’s quite possible to charge your phone’s battery without having the phone itself, you just need to know what means to use for this.

Turn on power saving mode or airplane mode

Enabling the energy saving mode for iPhones and Android devices will help reduce the charging time of the smartphone's battery by 20-30%, i.e. in real terms it will be 20-30 minutes. If you need to fill the indicator to only 30-40 percent, it will take no more than 30 minutes, with airplane mode turned on.

Airplane mode disables network search functions, turns off wireless interfaces wi-fi, bluetooth, GPS. All this significantly affects the power consumption of the device, therefore, the battery charges at an accelerated pace.

Question and answer

Is it possible to charge regular phone charging with higher or higher current?

Yes you can, but you have to be careful. Too much high voltage The power controller can be damaged; replacing this module is expensive. You should not exceed the current by more than two or three times, the battery will not be able to take more, but it is quite possible to burn the microcircuits.

Is it true that fast charging kills a li-ion battery?

If you use high-quality accessories, it is not possible to kill your smartphone battery. But if you conduct experiments and charge with a current of 3-4 amperes, then 100% you will have problems with the battery. Perhaps he will survive several cycles, but the consequences will be sad, in any case.

An adapter with increased current can only be used in emergency cases, so as not to kill the iPhone before the warranty expires.

How can I charge my phone through headphones?

No, this is only possible for some devices, for example, the iPod has this function. Such technologies also exist for smartphones, but they have not gained popularity due to their lack of ease of use by the end user.

How to charge a Samsung phone or iPhone via wifi?

There is no such possibility. Power controllers capable of detecting microwaves have not yet been invented. wifi radiation transmitters and convert them into energy to power batteries in sufficient quantities. If someone is trying to sell you something or sell you a service to remake an iPhone or Samsung, you are looking at a charlatan. Most likely he will simply destroy the device and disappear with the money.

Video

Leave him alone

Put your phone down and stop using it. The main reason why a phone's battery drains is because of its large and stunning screen. The more you use it, the more the battery will drain. Stop checking email, don't meddle in text messages while the phone is charging. Leave your phone alone.

Turn on Airplane Mode

Turning on Airplane Mode will speed up your phone's charging speed, but you won't be able to receive notifications or calls while in Airplane mode. The less your phone tries to do, the faster it will charge. Putting your phone in airplane mode disables its ability to generate wireless radio signals, thereby limiting the phone's functionality. This way the battery charges faster.

Turn it off

Turning off your phone is much more effective than putting it into airplane mode. The logic here is similar to what was said earlier. The screen is the main battery drain. Using your phone while charging slows down the charging process. To charge your phone faster, turn it off. However, you will not be able to receive SMS, calls or any other notifications. But it may be a small sacrifice if you want to charge your phone as quickly as possible.

Do not charge it using the computer's USB port

When connected to USB ports computer, the phone will charge, but this process will not occur correctly, that is, your phone will charge, but not at the same speed as if it were from a normal charger. In USB specifications 1.0 and 2.0, the port is capable of delivering up to 0.5A. In USB 3.0 specification, it can supply current up to 0.9A. But the dedicated charging port can offer up to 1.5A. USB 3.1 can supply up to 3A. Do you see the difference? So it's better to rely on a dedicated charger if you're in a hurry.

Do not use a wireless charger

Without a doubt wireless charging quite slow. This is why it is not recommended to use a wireless charger if you are in a hurry. However, the exception is fast wireless charging. It's more efficient than charging via USB, but still no better than a regular wired charger.

Buy a power bank

A power bank won't help you charge your phone faster, but it will give you the ability to charge your phone on the go. This can solve the problem of low battery and low time. Power banks are portable, i.e. They're easy to carry around, so you don't have to worry about forgetting to charge your phone. Yes, but don't forget to charge your power bank.
