Samsung phones that support wireless charging

enable, wireless, charging, Samsung

These are, of course, the latest flagship Galaxy S9 and S9 Plus, as well as last year’s Note Galaxy series.

Fortunately, induction charging was also available in slightly older devices. Galaxy S8, S8 Plus, and S7 and S7 Edge supported.

If someone is using older devices, there is nothing stopping the Galaxy S6 from charging this way. Unfortunately, this technology cannot be found in devices from the middle and lower price shelves of the Samsung.

As a result, in phones like a8 2018, a7 2018, a5 2017, a6, a9, j7, a3, j6, j5, j4 or j6, wireless charging is not supported, but on Samsung Galaxy Note 8 Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge, Note 5, no problem.

Does Samsung a8 2018 / a7 2018 / a5 2017 / a7 2018 / a6 / a9 / j7 / a3 2017 / j6 / s7 / j5 / j4 / j6 / s6 / c8 support wireless charging

Wireless charging is incredibly convenient, although it is not without its drawbacks, and although only a few phones support it, you can even turn it on at all How to do it I showed in the video at the bottom of the entry.

To make this decision easier, I’ve prepared a list of Samsung smartphones that support wireless charging. you can charge wirelessly.

Although the phenomenon of electromagnetic induction has been known since the middle of the nineteenth century, it is only now becoming generally accepted.

Unfortunately, the process is very slow, so most of the equipment is still powered by cables.

Induction devices are an extremely convenient solution, but there is one “but”. Samsung phones can be charged in this way if they support one of the charging technologies. “Qi” or “PMA”.

The first one, you will see in Apple, Xiaomi or LG, and the second is mainly supported by Samsung phones. Therefore, when choosing, be careful not to run into an incompatible smartphone.

ALL Galaxy PHONES: MISSING FAST WIRELESS CHARGE IN SETTINGS? FIXED! Galaxy S7, S8, S9, S10, etc

Samsung has been trying to promote wireless charging technology in its phone models for several years.

ATTENTION: if the manufacturer of your phone has not installed wireless charging, then you can do it yourself for any smartphone. details here.

Samsung wireless chargers. better or worse than traditional chargers

Mobile phones offer new technological solutions every year. Wireless charging isn’t new, but it’s no longer the standard when it comes to smartphones and tablets.

Wireless chargers are becoming more popular, but not as popular as NFC or LTE data transfer. What are the pros and cons of such recharging our batteries?

Some of you will probably notice that the method of recharging power in smartphones and tablets is not entirely wireless.

After all, the base must still be connected with a cable to a power source. It’s hard to disagree with this fact.

Going further along this line of reasoning, we can come to the conclusion that buying a universal docking station with microUSB output will lead to the same.

over, it will be a cheaper alternative. This is largely true. Probably the only practical difference is the need to properly connect a smartphone or tablet.

For wireless chargers, just place your phone on it. We will probably see more differences as soon as this technology becomes more developed and refined.

The main disadvantages of wireless chargers are longer battery life and more heat generated during the process.

These issues are obviously known to the organizations working on this technology and can be expected to be largely addressed in the near future.

Missing “Fast Wireless Charging” SOLVED! Galaxy S7, S8, S9, S10, Note 8, 9, 10, 10 Plus

Perhaps in the near future we will be charging our mobile gadgets on tables in cafes, chairs in cinemas or while traveling by train or bus. Success.

Which smartphones support fast charging?

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 mA / h. 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 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 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). Significant 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 “fill” in 30 minutes, and thoughtful power regulation will not allow high voltage and current to harm the battery.

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 Settings. Battery (Power or Battery), 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.

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 many 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 internal temperature of the phone 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 go for a walk, it is better to turn it on and leave it alone for a while.

Which smartphones support wireless charging

Samsung is among the leaders in the number of Qi-enabled smartphones released. Here is a list of Galaxy phones that come with it:

  • Note 5, Note 8, Note 9;
  • S6 / S6 Edge;
  • S7 / S7 Edge;
  • S8 / S8 Plus;
  • S9 / S9 Plus;
  • S10e / S10 / S10 Plus;
  • Note 10 / Note 10 (Note 10 Lite. no);
  • Z Flip;
  • Fold;
  • S20 / S20 Plus / S20 Ultra.

Accordingly, other Samsung Galaxy smartphones do not support wireless charging. Including the following Galaxy models from the list:

  • A8, A10, A30S, A31, A40, A41, A50, A51, A71;
  • M21, M31;
  • J3, J5, J7, etc.

Note! Even if your phone doesn’t support Qi technology, it’s easy to fix. There are special receivers for Qi, which are installed under the cover of the gadget or case. With their help, the gadget can be charged wirelessly.

Wireless charging technology on Samsung phones, which models support

Today, there are so many household appliances in apartments that the wires literally entangle the walls and get in the way. In this regard, Samsung is releasing phones with wireless charging. That is, in order to connect the gadget to power, you just need to install it on the charging station. Next, let’s take a look at how a wireless charger works and which Samsung Galaxy smartphones have it.

How wireless charging works

The technology of its operation is based on the principle of electromagnetic induction. And the standard describing the technology is called Qi.

The charging station is connected to the mains and converts the energy into an electromagnetic field. To receive energy, a Qi-receiver must be installed inside the gadget. The material of the phone case is also of great importance. Often models that support Qi technology have a glass or ceramic back cover.

Pros and cons of wireless charging

We figured out the principles of the technology. Now about its advantages:

  • there is no need to constantly connect the smartphone to the charging cable. You just need to place the device on the station and turn it on;
  • When using wireless charging, the state of the smartphone remains better than in the case of wired charging. And this is due to the fact that the cable connector does not wear out;
  • smartphones that support Qi have their own cooling system. It protects the battery from overheating. over, there is a ventilation system on the body of the product. Through it, the exhaust air is removed from the device;
  • Samsung charger fits any model that supports Qi.

Despite all the advantages, such charging also has disadvantages:

  • The charging station transfers energy to the battery 2–3 times slower than using a cable. And this significantly increases the time spent on food;
  • while charging, the user cannot move the smartphone away from the station more than 3-5 cm, which creates certain inconveniences. In addition, the battery recharge rate is slow, so the phone will not be able to perform resource-intensive tasks.

How to use Samsung Wireless Charger

The principle of operation of Qi technology is quite simple. In order to use it, you do not need to install additional software or special applications. ALGorithm:

  • put the smartphone back cover on the center of the station. A notification will appear on the screen about the estimated completion time of the process (depending on the conditions);
  • at the end of charging, disconnect the gadget from the power.

Observe the following precautions when powering the battery from the station:

  • do not connect the phone to the station if there is material between them that conducts current (magnet, metal, etc.);
  • use only original chargers, as Chinese fakes can harm the battery’s performance;
  • do not place the smartphone on the charging station in a case if it contains a card with a chip, RFID tag, etc.

It is also not recommended to perform resource-intensive tasks while charging (for example, run games at high settings), since the battery will quickly overheat.

As it turns out, wireless charging is easy and convenient to use. If the speed of battery replenishment is primarily important for you, then we recommend using a cable and an adapter, since the Qi standard is inferior to a classic charger in this indicator.
