Samsung Phones with Wireless Charging
Let’s talk about the Samsung phones with wireless charging and how the feature works. Wireless charging is not a new innovation but it has just only started becoming a thing in smartphones a few years back. The technology is not yet matured but it has improved year over year and manufacturers only put it on their flagship devices.

Wireless Charging in Samsung Phones
The first smartphones with wireless charging are the Samsung S6 series and almost all their flagship phones since then have come with this charging feature. Even till now, wireless charging is only available on Samsung S series and Note Series.
With wireless charging, you will be able to charge your phone without using physically plugging a cable into the charging port using electromagnetic induction.
So, how does this work, you might ask? Well, it involves the use of a silver-plated copper coil that both phone and charging pad has.
When you placed the part (usually the back) that contains the coil on the part of the pad that contains the coil, an electromagnetic field is created from which the phone generates an electric current which it then uses to charge its battery.
Just like normal charging, wireless charging has different standards but the most common one is Qi charging and it is the same one being used on Samsung phones.
Some of the phones with this technology also have reverse wireless charging which allows you to charge other devices such as phones, wireless earphones, smartwatches, etc.
It is hard to expect a wireless charging of like 45 Watts from Samsung when even the Samsung phones with the fastest wire charging are at 45 Watts. Hopefully, things will change in 2022.
Final Thought
Until the launch of the Google Pixel in 2020, it was believed that your phone must have a glass back for wireless charging to work, well not anymore. However as there are advantages to wireless charging, there are also disadvantages.
Some of which you can easily avoid such as the charging speed. Most of the latest Samsung phones with wireless charging support up to 15 watts (not that it is very fast) but that is only if you use a wireless charging pad made for Samsung.
Other disadvantages include:
- You cannot use the phone while charging it because immediately after the coils are no more aligned, the device stops charging. Which to some extent is not really a disadvantage in the sense that you are not even supposed to be using your phone while charging.
- It is slow. If you buy a charging pad that is not for Samsung phones, the charging speed will be 5 watts. Even if you do have a compatible pad, the highest it can go at least for now is 15 watts. Compare that with 25 watts and 45 watts of normal charging.
- It can damage items with magnetic stripes such as your credit card. This can happen if you are charging through a case and the case houses any of those items.
It is worth stating that wireless charging is still only available on Samsung flagships. The S and the Note Series. I will like to see it on the A series especially the upper mid-range.
