Plastic SIM cards are already dying a slow death. The future is eSIM technology. It is a separate chip that is built into the phone. What will change from using plastic SIM cards? Does the new modern eSIM technology have any pitfalls?

Fast charging is a technology that allows you to charge your phone more efficiently. Whereas previously the smartphone needed three hours to charge 100%, today less than half the time for the same battery size is just enough.

Modern smartphones have all sorts of fun features, but plugging in the charger and cable every day does get annoying. Read our tips to learn how to set up wireless charging so you can keep your phone powered 24/7.

A mobile phone is water resistant if it meets a certified level of durability that allows total immersion. When it comes to mobile phones, it is the specification of the IP67, IP68, or IP69 Ingress Protection rating.

IP68 indicates the degree of protection of a device that is fully protected against dust and can also withstand immersion in water for more than 30 minutes or in a depth exceeding 1m. However, the specific conditions are determined by the manufacturer.

Often dubbed the display of the future, OLED displays are usually found on premium products. They offer high quality, a broad range of colours, low power consumption, high brightness, and excellent black colour reproduction. As a result, OLED displays are easy to view even in bright sunlight. Another advantage is the wide viewing angle, which reaches nearly 180 degrees.

The wide-angle lens allows the device to take photos at a wider angle than the phone' s primary lens. Therefore you will be able to fit such things into picture, for which you would normally need to take a few steps back and that is not always possible, for example indoors.

A telephoto lens is a lens that allows you to “bring“ a distant object closer to your phone without physically approaching it. Most mobile phones zoom in two to five times.

Optical stabilization is a mechanism inside the lens that eliminates the effects of camera / lens shake on the captured image. This is done by moving the optical system inside the lens. It is often referred to as OIS (Optical Image Stabilizer). It reduces the camera shake and blur, for example at slow shutter speeds or long focal length lenses.

Zoom is the ability of the lens to bring distant objects closer. It is possible to change and adjust the focal length of the lens. The closer your subject is (shooting at a longer focal length), the more it reduces the aperture and the more likely it is for the final image to be affected by camera shake.

NFC (Near Field Communication) is a wireless communication used to establish a connection between portable devices, over a very short distance, only up to 4cm. Previously, NFC was used to transfer photos and videos, but you'll often hear about it in connection with contactless payments.

Bluetooth is the communication tool used by a huge amount of electronics. Learn how the frequency signal is generated and how it's used. In a simple overview of the different versions, we will show how Bluetooth has evolved and been refined. You can also learn something about the specifications and security of this communication standard.

A device that receives a GPS signal to determine and record a location. GPS modules can be found in car and motorcycle navigation systems, cyclocomputers, sporttesters and GPS locators.

Fifth generation of mobile networks, so-called 5G, is a new standard whose parameters significantly exceed the current 4G networks. It brings up to a tenfold increase in speed, which together with a reduction in response time guarantees a highly stable Internet connection for virtually any device.

LTE (Long Term Evolution) marks the next generation of mobile data networks. This is an intermediate step between 3G and 4G. Although manufacturers and operators sometimes mistakenly refer to it as 4G, it is not a full 4G network. That's for LTE Advanced. The maximum theoretical data transfer rate is up to 175Mbps for download and up to 57.6Mbps for sending data in one frequency band. 

NanoSIM is the smallest, most advanced type of SIM card.

Plastic SIM cards are already dying a slow death. The future is eSIM technology. It is a separate chip that is built into the phone. What will change from using plastic SIM cards? Does the new modern eSIM technology have any pitfalls?

The Lightning connector is used with iPhone models and various Apple products. It's a tiny (8-pin) duplex port that carries both digital signal and power. The proprietary Apple cable has a Lightning connector on one end (the one plugged into the phone) and a standard USB connector on the other, making it compatible with a PC or car charger. The iPhone 7 also uses it as a headphone jack adapter.

A digital compass (magnetic sensor) detects the earth's magnetic field to determine the cardinal points. This enables the phone to correctly rotate the map to fit your orientation.

Accelerometers and G-Sensors are motion sensors that determine the tilt in space. The phone uses it to know which way it is being held, e.g. portrait, landscape or upside down.

The motion of a gyroscope rotates in space on all three axes. In this case, it determines the direction in which you are moving your phone.

An ambient light sensor that monitors the ambient light levels and dynamically adjusts the display backlight intensity. A practical and handy feature, it is part of most modern phones. It turns the display brightness to the maximum in bright sunlight and dims the backlight in the dark. This makes the phone’s display perfectly readable in all lighting conditions without straining your eyes.

The vast majority of modern mobile phones are equipped with a proximity sensor. Its task is to evaluate the distance of an object from the sensor. Once the object gets close, the telephone activates a particular function. One of the most common is the function to turn off the screen and the touch layer when the user dials a phone number and places the phone close to his ear.
