All About Samsung Fast Charging. User Guide

Samsung fast charging is one of the innovations of the well-known Korean brand, which significantly speeds up the process of charging a mobile device. Users are happy to use it, because it is so pleasant. not to wait several hours until the battery is fully charged, but to get the result within less than an hour. However, few people know how this option works, how it can be configured and even disabled.

What is Fast Charging in a Samsung smartphone

A standard charger in modern smartphones has a capacity of 10 watts. In phones with support for Fast Charge charging, the declared power of the adapter is 20 watts (in practice, this figure rarely exceeds 18 watts) Accordingly, the more the power of the unit increases, the faster the battery is charged.

How Samsung Fast Charging Works

The Samsung Adaptive Fast Charging technology is based on a stepwise change in current rates depending on the percentage of battery charge. The lower the percentage of charge, the more power is delivered by the adapter.

As the percentage of charging increases, the current setting in the adapter changes. The power gradually decreases to 10 watts at a 95% charge level. In this case, the decrease does not occur smoothly, but in stages. This significantly reduces the efficiency of recharging the battery, since the controller does not fully control the current changes. This bug was fixed in the updated Quick Charge 3.0 standards and all subsequent versions. the voltage during such charging changes in 0.2 volt steps, which is more efficient and safer for the phone battery.

Quick Charge compatible

Samsung Fast Charging is compatible with any Quick Charge-enabled device. With this adapter, you can charge any device with the Quick Charge 2.0 or Quick Charge 3.0 logo. In this case, keep in mind that the process will take place according to the standard of the 2nd version. A smooth power change will not work in this case, and the phone will charge a little slower than on the adapter of the third version.

Missing fast charging on Samsung. reasons and what to do?

To begin with, we note that a full battery charge within the terms stated by the manufacturer is guaranteed only if during the process you do not use the phone and separate applications are not running on it in the background. Any running process will decrease the speed of the process to one degree or another, depending on the energy consumption of the application processes. Most of all, the charge is taken up by the turned on screen and running multimedia files. If you notice that the phone is charging too slowly. check if you have any additional services or applications enabled.

Also check if the option is active using the special section in the settings, which was mentioned above. You may have previously accidentally or intentionally disabled it.

If charging is pathologically slow or does not work at all, check the serviceability of the adapter itself using another device, and the connector on the phone using another cable. If you notice a malfunction, contact the service center to fix the breakdown.

How to enable fast charging on Samsung

If you have recently disabled the option, you can do this in the system settings. Using the example of disabling the option, consider how to reverse this process.

Fast Charge is a unique technology that makes our life much easier. Many people are still afraid to use it, believing that it harms the phone’s battery and wears it out faster. However, numerous tests and tens of thousands of satisfied customers prove that this option works exclusively for the benefit of the user.

Using Fast Charging on Samsung Phones

No matter what smartphone you use, you will constantly monitor the battery level and regularly connect your mobile device to a power source. Different models of mobile devices take different time to replenish the battery. Fast charging technology helps to reduce it. Today, more and more Android and iOS devices are receiving this feature. From the name of this technology, it follows that, subject to certain rules, the phone can be charged up to 80% in just half an hour.

Some Galaxy S10 phones (S10, S10 Plus and S10e) use a 15W charger (Qualcomm QuickCharge 2.0 technology), Samsung Fast Charge for the Galaxy S10 5G is rated at 25W, and the S20 and Note 10 adapter supports 45W The standard charger, with which most phones are charged, has 10 watts.

Quick Charge Basics

So, we know how batteries are charged and discharged. But fast charging is different from normal charging, and in order to understand how it works, you have to learn a little about what a battery charge controller is. You will also have to remember from the school physics course that voltage is measured in volts, current is in amperes, and watts are a unit of measure for power, that is, the amount of energy that is consumed per unit of time.

Higher amperage and higher voltage charge the batteries faster. But when it comes to the battery, these parameters are limited.

Smartphone batteries are recharged when an electric current flows through them. But it must be remembered that the battery cannot take on infinitely much current; at peak loads, it breaks down and collapses. This is where you need a device such as a charge controller. This controller protects the battery from dangerous current peaks. It regulates the flow of electricity that goes into and out of the battery. Simply put, controllers regulate the current (in amperes) at which the charging process takes place, measuring both the strength and the voltage. They do not allow critical exceeding the permissible parameters that can damage the battery.

Acceptable / standard values ​​for USB charging are shown in the table below.

Voltage Current strength Max. power
USB 1.0 5 in 0.5 A 2.5 watts
USB 2.0 5 in 0.5 A 2.5 watts
USB 3.0 5 in 0.5 / 0.9 A 4.5 watts
USB 3.1 (USB-C USB-PD) 5–20 V 0.5 A / 0.9 A / 1.5 A / 3 A / 5 A 100 watts

How to Activate or Deactivate Fast Charging on Samsung Phone

You can enable or disable the fast charging function in the settings. There are two ways to get into the settings on Samsung phones:

  • lower the notification curtain and tap the gear icon, then open the “Settings” section;
  • tap on the “Settings” application icon, which is located on the home screen of the phone.

In the settings, open the “Optimization” section, then go to the “Battery” section (the icon in the lower left corner). The next step is to go to “Advanced Settings”. To enter this menu, find three dots in the upper corner on the right side of the screen and click on them. In the “Additional settings” there is an item “Fast charging”. Turn it on by sliding the slider all the way to the right. If fast charging is already on, and you want to turn it off, then put the slider in the extreme left position.

Samsung Adaptive Fast Charging

  • the technology is used in the vast majority of Samsung devices;
  • technology compatible with Quick Charge 2.0.

Disadvantage. there is some conservatism of the manufacturer regarding the further improvement of this standard.

Initially, Samsung only used Adaptive Fast Charging on its Galaxy series devices. Unlike Quick Charge and other rapidly evolving standards, adaptive charging is fully compatible with the Exynos on-chip system commonly found in devices intended for sale in the global market. Adaptability implies the ability to vary the process for different conditions. As for charging, in this case, its power changes / adjusts. When the battery is heavily discharged, it charges with increased power. As soon as the battery reaches a sufficient level, the power decreases, but not smoothly, but in steps.

There are several charging options available for Samsung devices today. Now it is not only 18 watts, but also 25, and even 45 watts. Support for higher indicators was carried out not in hardware, but at the firmware level.

If a Samsung phone owner intends to use Adaptive Fast Charge for their device, they must additionally purchase a certified cable and adapter. By the way, there are also devices for car and regular fast wireless charging on sale. However, most Samsung smartphones support Quick Charge compatible accessories.

How Standard Charging Works

Let’s remember the main points: every mobile phone is powered by a rechargeable battery, and each battery functions according to more or less the same principle. It consists in the fact that the battery has two electrodes. positive and negative, anode and cathode. The electrodes are immersed in electrolyte. This is a special liquid that is a catalyst for physicochemical processes, during which the movement of electrons from the anode to the cathode occurs. When electrons move, an electric current is generated, which feeds the battery and charges it.

In disposable batteries, which cannot be recharged, the chemical reactions that trigger the flow of electrons only occur once. After that, the batteries become unusable. But in a lithium-ion battery with reusable charging cycles, as used in a smartphone, these reactions are renewable. During the period when the battery is gradually discharged, chemical reactions generate electricity. When the battery is recharged, these reactions, on the contrary, absorb energy.

Fast charging standard

USB Power Delivery (USB-PD) technology has become the standard for fast charging. It was developed several years ago to transfer power in larger quantities. The maximum power of USB-PD, as we can see in the table, is up to 100 watts. Consequently, from the USB-PD connector, you can charge not only smartphones, but also some laptops that are equipped with USB-C.

The advantage of the USB-PD standard is that portable chargers that have a USB-C port can serve as a power source for other gadgets, or, conversely, these chargers can take charge for themselves, being powered by energy from third-party devices. USB-PD chargers are capable of transferring energy at high speed, for example, to a smartphone battery. And then, also at the highest speed, charge the laptop.

Different manufacturers use the USB-PD standard in different ways, each has its own pros and cons.

Why fast charging doesn’t work

Often on the Internet, owners complain that the smartphone has stopped working normally. fast charging has disappeared. When the phone has a “fast charge”, but this function does not turn on or suddenly stops working, you need to find out the cause of the problem. There may be several reasons why the device takes longer to charge than usual:

  • use of non-certified accessories. adapter and cable;
  • physical malfunction of the phone connector or adapter / cable for connecting power;
  • deactivated (in software settings) fast charging function;
  • using the phone while charging (screen backlight on, running apps).

What can be done to make the smartphone charge quickly? First of all, check if the corresponding option is enabled in the “Settings” section. Then stop applications running in the background and do not use your phone while it is charging. Purchase and continue to use only manufacturer-approved accessories.

As a conclusion, we can say that Samsung Adaptive Fast Charge technology is an innovation that is very much in demand in modern conditions, which, if used correctly, does not harm a mobile device and allows the phone to be prepared for further work much faster.

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 in the kit, then take 2 A and the charging time will be approximately halved. But do not forget that this will not add “life” to the battery “, but will shorten its operating life.
Now let’s move on to considering the technology itself. In fact, the “trick” 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 small software improvements with a minimum of movement on the “hardware”.

  • Quick Charge 2.0: Recharges the battery to 50% in approximately 30 minutes
  • Quick Charge 3.0: the battery is charged 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 unit itself, while the control is left to the mercy of the processor (from Qualcomm, of course). Substantial hardware work has been done here.
The main function of Quick Charge is to recognize the current state of the battery and properly adjust the power supply. In this case, charging from 0 to 60% will be much faster than charging from 60 to 100%. In this situation, from 0 to 50% the battery will be “filled” in 30 minutes, and thoughtful power regulation will not allow high voltage and current to harm the battery.

Which smartphones support fast charging?

These 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 of.

How to enable or disable fast charging on Android (instruction)

Now visitors to RulSmart often ask a 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, it all looks interesting enough, 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 multiples. 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 disable fast charging

Not every device can boast of the ability to programmatically disable fast charging. Nevertheless, 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 shorten the battery life so much. By the way, fast charging also leads to excessive heating, which is not good.

Huawei has exclusive fast charging SuperCharge

The Chinese electronics manufacturer began developing its fast charging protocol even before the trade wars and disagreements with other countries. Like many others, it is based on Quick Charge 2.0 and is backward compatible with that standard.

SuperCharge has been supported by all of the company’s smartphones for the past few years. In this case, the charge comes from a 25W power supply, the voltage does not rise above 5V, and the current strength changes from 4.5 to 5A.

Fast charging trick All Samsung Devices 101% Working trick

SuperCharge only works with Huawei-branded AC adapters or external batteries, no third-party certification for compatible accessories.

⚡ Record rates of charging using this technology are considered to be charging a 4200 mAh battery from 0 to 100% in 1 hour and 10 minutes.

How to disable fast wired charging on Samsung a50

As for how to turn it off, after the way to turn it on is described, I doubt that an instruction is also needed for this.

Just move the slider from right to left so that it changes from blue active to gray inactive. Success.

Fast charging: general information

Today, a conventional charger delivers 10 watts of power. If your phone supports fast charging, the battery can be recharged with a high power adapter. In theory, the power can be 20 watts, but in practice, manufacturers are limited to 18 watts. The higher the power, the faster the battery charges.

The first fast charging technology was developed by Qualcomm, which introduced the Quick Charge 1.0 standard in 2013. Today, the QC 1.0 standard is not used, since it has been replaced by more efficient technologies, from QC 2.0 to QC 4. There is even Quick Charge 5.0, but there are no smartphones supporting this protocol at the beginning of 2019 yet.

Since Quick Charge is a proprietary technology that requires royalties to be transferred, the Korean company has developed its own Samsung Adaptive Fast Charging standard. Samsung Fast Charging is based on the Quick Charge 2.0 standard and is compatible with QC certified chargers.

Samsung Fast Charge for Galaxy: The Complete Guide!

Many Samsung smartphones support fast charging, and this raises a number of concerns for some users. The main issues are related to the safety of the technology itself and the life of the battery, which is being charged at an accelerated rate. The compatibility of Samsung fast charging with Quick Charge and alternative technologies from other manufacturers raises a lot of questions.

In this post, we will give answers to the most common questions, and at the same time we will tell you how you can turn off Samsung Fast Charging at the operating system level, and how to turn it back on.

Do I need to disable the fast charging function?

You can turn off Samsung fast charging, but it’s hardly advisable. Overheating does not threaten your smartphone, unless you charge your Samsung Galaxy on a windowsill, on a car dashboard under the sun, or on a couch under a pillow. By the way, in all these cases, disabling fast charging does not protect against critical overheating.

If you’re playing, flipping through Instagram, chatting on social media, or watching a TV show while charging, your Samsung Galaxy will automatically go into normal charge mode and start charging slowly. You don’t need to forcibly disable fast charging in the settings.

The heating of the Samsung Galaxy at this moment is due to the simultaneous operation of the processor, screen, various controllers and the battery, but not fast charging.!

Forcing Samsung Fast Charging to turn off is a redundant preventative measure, but it can still be used in some cases. For example, if you’re charging your Samsung Galaxy in the evening, when speed doesn’t matter anymore. In such a situation, you can turn off fast charging just as unnecessary.

Tips for Proper Battery Use

It became clear how to charge the gadget as quickly as possible. Is it possible that the precious charge that the battery has received can be used especially carefully?

Dear friends! I hope you figured out the issue, disabling fast charging on the phone.

How to enable Fast Charge on your Samsung smartphone

One of the characteristics of a smartphone. the battery capacity, today is becoming one of the most important parameters of a mobile device. Therefore, if we paraphrase the phrase from the song of the water carrier from the legendary Soviet film “Volga-Volga”, then for modern smartphones it will sound like this: “And without a charge you are not there, and not syudy!”.

The battery life and the rate of its consumption depend on the time of independent operation of the smartphone. And if you are in an area where there is no access to an outlet with the inscription “220 V”, then after a while your smartphone may turn into a rather nice flat box, from which there will be no sense. there is no telephone connection, no Internet. no toys to play with.

Therefore, an ordinary electrical outlet for our phone becomes source of life-giving current, where it can be “saturated” with energy. And here, the faster your phone is charged, the sooner you will receive the long-awaited “mobility” of your communication device.

How to turn fast charging on and off on Samsung Galaxy?

How to disable Fast Charging on Samsung Galaxy (S7, S8, S9 and any other model)? Why you need to disable and enable fast charging?

Everyone loves when their devices charge quickly, right? This is why so-called fast charging technology is so popular. at the moment, almost every phone manufacturer has its own version. However, in some cases, fast charging may not be the best solution.

Thankfully Samsung understands the need to disable this option on the fly, and there is a way to do it on Galaxy devices running Marshmallow (and other Android versions) such as S9, S8, S7 / Edge, S6 Edge, S6 and Note 5.

Why you need to disable Fast Charging on Samsung Galaxy?

But before we start, let’s take a closer look at the reasons, because I know a lot of people don’t understand: why would anyone want to disable fast charging on Samsung? There are several reasons, but the main one is heat, or rather, overheating. Fast charging uses a lot of current in a short time, so the device can easily overheat.

If it sits on a nightstand in a cool, ventilated area, this may not be a problem. But if the phone is on your lap while you are driving and the sun is falling on you, the device can get quite hot

On the other hand, devices like the Galaxy S7 / Edge with wireless charging have a fan in the charging cradle that can turn on when in use. Some people hear this faint noise and find it annoying, and disabling Fast Wireless Charging prevents it from occurring.

How to Disable or Enable Fast Charging on Samsung Galaxy?

Now that you know why you should enable or disable fast charging on Samsung, let’s take a look at how you can do it. The good news is incredibly easy and you are just a few taps away from success.

I’m using the Galaxy S7 Edge for this tutorial, but the process is pretty much the same for all Galaxy devices. just keep in mind that if the device doesn’t have wireless charging, the menu might look slightly different.

The first thing to do is go to the Settings menu by pulling down the notification bar and touching the cog icon in the upper right corner.

Scroll down the menu until you see Optimization. Click on it.

Now go to the bottom of this menu. Depending on the device, there are one or two options here: “Fast Charging” and “Fast Wireless Charging”. Toggling the slider to the right of any option enables / disables it.

It’s especially good that Samsung has separated these options so that you can choose to continue to charge quickly via the cable, but disable this feature for wireless charging, or vice versa. As you wish.

Why Sometimes Fast Charging Doesn’t Work on Samsung?

Even when this feature is enabled, the phone won’t always charge quickly, as noted by Samsung users. If you use your phone while charging or leave the screen on, it will charge much more slowly. It takes about three hours to fully charge a Galaxy S8 with the screen on. the same as a “regular” charge.

“Remember, just because you see the Quick Charge icon when you are using your device does not mean that you are really getting the maximum charge. This does not happen until the screen is turned off ”.

You will not find this helpful tip in the Galaxy manual.

And this isn’t the first time something gets in the way of fast charging. Google Pixel disables fast charging when the phone’s internal temperature goes over a certain threshold.

In my time with the Galaxy S8 Plus, I noticed a significant difference in how quickly it charges if I use the battery at the same time. But it never dawned on me that fast charging doesn’t really work when the screen is on or the phone is in use.

In this case, if you need to quickly charge your Galaxy S8 before you go on the road or out for a walk, it is better to turn it on and leave it alone for a while.
