The telephone in the 21st century is a device that has changed our lives. Thanks to him, we were able to learn new things, share photos, videos, audio over great distances with a single movement.

fingers, build routes, track the location of the desired bus, publish in

social networks, count the number of steps and much more. But a few decades ago, at the beginning of its formation, mobile technologies were completely different. Owners

good physical shape was required in order to be comfortable enough to use heavy and

bulky gadgets. In addition, it was necessary to have access to an electrical outlet in order to

use the first mobile devices, since batteries were not yet built into them. Sounds difficult, doesn’t it?

Fortunately, technology has come incredibly far since then, with a particularly large qualitative increase occurring over the past ten years. Mobile devices have become smaller, more powerful and far more useful. They have penetrated all areas of our lives, and their role continues to grow.

The availability of all kinds of smartphones, tablets, e-readers, now even smart watches and, in the near future, smart glasses, contributes to their rapid spread around the world. And, of course, all these billions of mobile devices have a serious impact on the quality of our lives. But this is now, and what will happen next is an interesting question.

In this article, we will try to analyze the most likely ways for the further development of the smartphone.

First, there will be a change in the structure of the battery. They will be flexible and multi-cell. For several years now, there has been news that scientists have discovered a way to create flexible batteries. It is the release of flexible batteries that will make it possible to produce flexible phones.

Smartphone batteries will remain lithium. This is facilitated by the growing demand for electric vehicles, which require a lot of high-capacity batteries.

Research into lithium cells will further increase charge storage density to accommodate more amp-hours in the same size.

Since the problem of accepting large charging currents for lithium still does not seem to be easily solved, multi-cell batteries will become popular. The use of multi-cell batteries will increase the speed of fast charging. This means that it takes only 6 minutes to charge a smartphone with such a 9 Wh (about 2500 mAh) battery from 0 to 100%.

Wireless charging technology will also improve. The power of induction pads should grow, smartphones of the future will charge wirelessly faster. Also

it is very likely that a standard will appear that allows you to charge the device at a distance from the station.

Of course, we are not talking about ten meters, but by 2050 devices should appear that can cover part of the room with an electromagnetic field.

Secondly, the capabilities of smartphones will become wider. Progress is expected in the field of VR and AR technologies. Virtual reality tools will become more popular, there will be more content, its quality

will increase. Augmented reality in 5-7 years will already be commonplace, thanks to an increase in the number of cameras and sensors, the AR capabilities of smartphones will expand.

To increase the level of data protection, manufacturers will develop new, more advanced ways to lock smartphones. In order to unlock the smartphone, the owner will only need to take it in his hand, putting his finger in the scanner area, and just look at the screen. In this case, the chance of unlocking by an outsider will be zero, since this will have to

fake a face, a print and a pattern on the eye at the same time.

Thirdly, it is supposed to control the power of thought. Previously, the main way to interact with the phone was the physical keyboard. Over time, it was replaced by touch screens, which

we use today. Thanks to voice assistants, we can now interact with our devices simply by using our voice.

As the next step in this evolution, the use of the power of thought suggests itself.

This technology will allow you to mentally complete any task that you are currently solving with a tap or voice. You can open the app of your choice, play a specific video, send a text, control the screen brightness, or create a clip from the videos you’ve taken. Such smartphones could be used much faster. You no longer have to search for an app to open it or drag your finger to the top of the screen to touch it. You could complete any task in the blink of an eye.

We are still far from having something like this become a reality, but scientists are making progress in this area. Back in 2017, a division of Facebook was developing technology that allows people to type with their minds. The predicted typing speed was 100 words per minute, which is about five times faster than typing on our current smartphones. The good news is that someone is already trying to develop a technology that could play a big role in our lives sometime in the future.

Fourth, it will be possible to choose a color while using a smartphone. After all, choosing a color when buying a smartphone can be difficult. Black, silver and white are more classic but also boring. Red, green, or purple hues stand out, but can give devices a toy, less solid look. With the smartphones of the future, you may no longer have to choose.

Imagine a phone with a transparent glass-like back that completely absorbs light.

The device will have one or more LEDs inside, the color of which can be changed in the phone settings. When you select orange, the entire back cover completely absorbs the light of that color and looks exactly the same as if

she was dyed.

This technology will allow you to switch between different colors as often as you like. This feature can also be set to automatically change colors on a daily basis. WITH

several LEDs inside, arranged in a certain way, you can also create gradient colors.

The next assumption is the alternation of display types. OLED screens are great for watching videos and playing games, but not for reading, for which e-ink screens, as in

e-books are a much better option. Eyes do not strain after several hours of reading, and you can also read outdoors, in direct sunlight. Sure, features like night mode filter out blue light and can even turn the screen to monochrome, but OLED displays still can’t come close to e-ink technology in terms of readability.

Imagine that the smartphones of the future could combine OLED and e-ink technologies, which would probably kill e-readers as a device class. With a simple click on

settings, you can turn the OLED display into an e-ink screen for reading books, articles and various documents, while all this light will not hit your eyes. Screen with

e-ink is also much less power hungry, which can result in longer battery life.

These were some of the main assumptions about the functionality and appearance of the smartphone of the future, but let’s consider the situation if it is not a phone, but something else. For example, glasses. They will use bone conduction technology or something even more high-tech. They will also be able to play music, offer turn-by-turn navigation, and read emails and texts you’ve received. All these things can also

displayed in front of your eyes using AR technology.

Of course, the glasses should have a built-in camera. When you want to take a picture, a frame will appear in front of your eyes,

showing exactly what the camera will capture. Say something like “click” in your head and the shot is taken. With AR technology, the glasses will project a screen/image in front of

you, allowing you to watch your favorite shows, play games, view camera pictures and web pages. It turns out that you do not have to buy a separate TV, which

save money as well as space in your home.

Many companies are already working in the field of smart and connected glasses. In addition to Google, a few years ago, Intel demonstrated smart glasses that project in front of

you the flow of information (direction hints, notifications…). But, unfortunately, she has already abandoned this technology. North, backed by Amazon, was working on a similar

idea in their Focals glasses. However, Google later bought the company and closed the project.

In addition, there are mixed reality headsets such as the Microsoft HoloLens that display holograms in front of your eyes, although they are currently aimed at business users. In principle, we have considered the most probable outcomes of events and development of technologies. Through

a few decades, let’s see what of this turned out to be true, and what will come true in the near future.
